-			   Groff Bug Report
-
-Please read the PROBLEMS file before sending in a bug report.
-
-Please fill in all fields, even if you think they are not relevant.
-
-Please delete the text in brackets before sending it in.
-
-Please report separate bugs separately.
-
-Send the completed form to bug-groff@gnu.org
-
-GROFF VERSION:
-[The version of groff you are using.  For example, `1.05']
-
-MACHINE:
-[The machine you are using.  For example, `Sun SPARCstation 2']
-
-OS:
-[The operating system you are using.  For example, `SunOS 4.1.1']
-
-COMPILER:
-[The compiler you are used to compile groff.  For example, `g++ 1.40.3']
-
-INPUT FILES:
-[Include all the files necessary to reproduce the problem that are not
-part of the standard groff distribution.  This includes font
-description files, DESC files and macro files (with the exception of
-the -ms and -mm macros: we have them).  Send them as a shell archive or
-as a uuencoded, compressed tar file.
-
-It's easier for us if you can provide an example that doesn't depend on
-any macro package, but obviously if you're reporting a problem with a
-macro package that won't be possible.  Also a short example is more
-convenient than a long one, but don't worry if you can't find a short
-example.  Don't say something like ``any file that X'': Always send a
-definite example.]
-
-COMMAND LINE:
-[The command line that we should run in order to observe the bug.  For
-example, `gtroff -Tps bug.tr'.  If the command line uses -ms or -mm,
-say whether these refer to the groff versions or the Unix versions of
-the macros.]
-
-DESCRIPTION OF INCORRECT BEHAVIOUR:
-[What goes wrong when that command line is run?  For example, `gtroff
-gets a segmentation fault', or `The output looks bad because the bar
-over the x is too long and is too far over to the left.'  If you get an
-error message, include it here without modification: Don't edit it to
-make it more readable.]
-
-SUGGESTED FIX [optional]:
-[If you can suggest a fix for the problem, include a context diff here. 
-But don't delay sending in a bug report in the hope of finding a fix. 
-Guesses about the cause of the bug are not usually helpful.]

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-     51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	    How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year  name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-
-	Another round in fixing getopt problems.  Hopefully the last one!
-	This time we use the getopt stuff from gnulib and define a prefix
-	unconditionally so that there are no collisions with any other
-	getopt implementations.  This is a slight waste of space in case
-	we already use a GNU getopt implementation, but on
-	the other hand it really simplifies life.
-
-	* src/include/getopt.h: Use gnulib version.
-
-	* src/include/getopt_int.h: Use gnulib version.
-
-	* src/include/groff-getopt.h: Removed.  Obsolete now.
-
-	* src/include/lib.h: Regarding getopt, don't handle any platform
-	specially; just include getopt.h.
-	(__GETOPT_PREFIX): Define (before getopt.h).
-
-	* src/include/Makefile.sub (HDRS): Updated.
-
-	* src/libs/libgroff/getopt1.c, src/libs/libgroff/getopt.c: Use
-	gnulib version.
-
-	* src/libs/libgroff/Makefile.sub (EXTRA_CFLAGS): Set

-
-	* src/utils/pfbtops/pfbtops.c, src/utils/xtotroff/xtotroff.c
-	(__GETOPT_PREFIX): Define (before getopt.h).
-
-2005-06-21  Werner LEMBERG  <wl@gnu.org>
-
-	* src/include/lib.h: Provide a fix for Mac OS X to not include

-
-2005-06-20  Denis M. Wilson  <dmw@oxytropis.plus.com>
-
-	* font/devps/prologue.ps (EP): Dont' use `bind'.  Reason: Using
-	`bind' to define a procedure which contains `showpage' means that an
-	invocation of `showpage' may execute wrongly (the exact effect
-	depending on the interpreter).  Not usually a problem except under
-	transformations, such as combining pages.
-	(PEND): Don't call `clear'.  Reason: Using `clear' in the definition
-	of /PEND means that stack underflow will occur if the stack is
-	deliberately non-empty before document inclusion.  If included
-	files are found to be generally badly behaved, we could replace the
-	`clear' with `mark' in /PBEGIN and `cleartomark' in /PEND (I've
-	never found this necessary).
-
-2005-06-20  Jörgen Grahn  <jgrahn@algonet.se>
-
-	* src/preproc/soelim/soelim.cpp (do_file): Append trailing zero
-	earlier to get correct error message.
-
-2005-06-16  Bernd Warken
-	* src/roff/nroff/nroff.sh: Add support for iso-8859-15.
-
-2005-06-15  Werner LEMBERG  <wl@gnu.org>
-
-	Another try to update getopt files.  This time we add a dummy
-	gettext.h file to satisfy the dependency.
-
-	* src/include/getopt.h, src/libs/libgroff/getopt.c,
-	src/libs/libgroff/getopt1.c: Updated from GNU libc CVS.
-
-	* src/include/getopt_int.h: New file (from GNU libc CVS).
-
-	* src/include/gettext.h: Dummy file which just defines a gettext()
-	macro.
-
-	* src/include/groff-getopt.h: Updated.
-
-	* src/include/Makefile.sub (HDRS): Add getopt_int.h and gettext.h.
-
-
-	* src/libs/libdriver/input.cpp (IntArray): Remove superfluous
-	`const' keywords in return value.
-

-
-	These patches modify the indentation implementation to use `<p
-	style=margin-left: n%>'.  Many thanks to Peter and Larry for
-	suggesting this solution.  Grohtml only uses tables for `.IP' and
-	related tags when the first operand has a short width.
-
-	Similarly, they modify all vertical space code.  By default, grohtml
-	sets up a style sheet which uses no vertical space between `table',
-	`pre', and `p' tags.  It forces spaces when it needs them using
-	`style="margin-top: 1em"'.

-	2004-09-19.
-
-2004-09-23  Werner LEMBERG  <wl@gnu.org>
-
-	* tmac/an-old.tmac (ne): Using default scaling operator.
-
-2004-09-19  Keith Marshall  <keith.d.marshall@ntlworld.com>
-
-	This change implements the following features:
-
-	PORPHANS
-	  New numeric register: Defines number of lines following LP, PP,
-	  QP, IP or XP, which must be kept together, before any automatic
-	  page break.  If insufficient space remains on the current page, a
-	  page break is forced before the new paragraph begins.
-
-	HORPHANS
-	  New numeric register: Sets number of lines of following paragraph
-	  which must be kept with a heading, defined by NH or SH, before any
-	  automatic page break.  If insufficient space remains on the
-	  current page, a page break is forced before the heading.
-
-	GROWPS
-	  (Thanks to Joerg van den Hoff, for this idea).
-
-	  New numeric register: Sets the first level of heading (set with
-	  NH), which will keep the same point size as body text; e.g. if
-	  GROWPS is set to 3, .NH 3, .NH 4, ... will produce headings at the
-	  point size specified by \n[PS], but .NH 2 and .NH 1 will have
-	  progressively larger point sizes, determined by \n[PSINCR] (see
-	  below).
-
-	PSINCR
-	  New numeric register: Sets the point size increment for each level
-	  of heading, (set with NH), below the threshold level set by
-	  GROWPS; e.g. if \n[PS] = 10, \n[GROWPS] = 3 and \n[PSINCR] = 2.0p,
-	  then .NH 1 will produce 14pt headings, .NH 2 will produce 12pt,
-	  and all other levels will remain at 10pt, (because \n[PS] = 10).
-
-	SH
-	  Existing macro now accepts a numeric argument, to make heading
-	  size match that of NH with same argument value, when the
-	  GROWPS/PSINCR feature is enabled.
-
-	SN-DOT
-	  New string, set by NH macro, replaces the existing (undocumented)
-	  use of SN, to represent the assigned section number.
-
-	SN-NO-DOT
-	  New string, set by NH macro, represents the assigned section
-	  number, but omits the terminal period (periods at intermediate
-	  levels are retained).
-
-	SN
-	  String set by NH macro, originally undocumented, now implemented
-	  as an alias for SN-DOT (which reproduces original behaviour).
-
-	* tmac/s.tmac (PORPHANS): New register.
-	(par*start): Use it.
-	(HORPHANS, GROWPS, PSINCR): New registers.
-	(SH-NO-TAG, @SH): Use them.

-	is extremely time-consuming to produce, given that HP's metric
-	files are very rudimentary.

-	the hyphenation algorithm to make it more flexible (e.g. allowing

-	languages like German would benefit).

-
-2000-02-06  Werner LEMBERG  <wl@gnu.org>
-
-	I've considerably modified the directory structure of the
-	distribution to get a more vertical layout.  For example, the number
-	of top level directories has been reduced from 42 to 6.
-
-	As a consequence, many changes, especially to the makefiles, were
-	necessary:
-
-	* The makefile variables `top_builddir' and `top_srcdir' have been
-	introduced.  Virtually all relative paths have been replaced with
-	absolute ones using these two variables.
-
-	* Dependencies (in the files `Makefile.dep') are no longer part of
-	the distribution.  Instead, they are created during a `make install'
-	in the build directory.
-
-	* aclocal.m4 (GROFF_SRCDIR, GROFF_BUILDDIR): Two new functions to
-	make `top_srcdir' and `top_builddir' absolute.
-
-	Some other changes:
-
-	* Man pages now depend on the files `VERSION' and `REVISION'.
-
-	* The added shell script `mkinstalldirs' will replace `mkdir' in
-	almost all cases.
-
-	* VERSION: Version number increased to 1.16.
-
-2000-02-04  Werner LEMBERG  <wl@gnu.org>
-
-	* grops/psrm.cc (read_one_of): Fixed pointer incrementation.
-
-	* Makefile.in: Removed $(tmac_m) since it is no longer needed
-	(after an update of the mm stuff).
-
-	* troff/Makefile.sub (majorminor.cc): Fix dependencies.
-
-2000-02-03  Werner LEMBERG  <wl@gnu.org>
-
-	The .psbb request will now also accept Mac PS images (i.e. using LF
-	as the EOL character).
-
-	* troff/input.cc (ps_get_line): New function, taken from psrm.cc
-	(with slight modifications).
-	* troff/input.cc (do_ps_file): Use it.
-
-	* test-groff: Add grohtml and grolj4 output devices to PATH.
-
-2000-01-30  Werner LEMBERG  <wl@gnu.org>
-
-	* NEWS, MORE.STUFF: Updated.
-
-2000-01-30  Cary D. Renzema  <caryr@dollar.mxim.com>
-

-
-	* pic/lex.cc, pic/pic.y: Implement it.
-	* pic/pic.man: Document it.
-	* pic/pic.cc, pic/pic.tab.h: Regenerated (with yacc).
-
-2000-01-30  Werner LEMBERG  <wl@gnu.org>
-
-	Add a new request `.psbb'.  This does exactly what the external
-	program psbb did.  It scans a PostScript image file for a
-	%%BoundingBox comment and extracts the bounding box values (in
-	PostScript units) which	are then stored in the four new (read-only)
-	number registers `llx', `lly', `urx', and `ury'.
-
-	This will allow the usage of the .PSPIC macro without worrying
-	about unsafe behaviour of groff, i.e., it will work without the
-	`-U' switch of groff.
-
-	* troff/input.cc: Implement it.
-	* tmac/tmac.pspic: Use it.
-	* troff/troff.man, grops/grops.man, NEWS: Document it.
-	* psbb/*, Makefile.in: Remove it since it is no longer needed.
-
-	This is bloody C code simply adapted from psbb.c!  Any improvements
-	welcome.

-
-	Removed obsolete .LINK macro completely.
-
-	The macros .URL, .FTP, and .MAILTO now accept a third argument which
-	will be immediately appended to the second argument (to be used with
-	punctuation, for example).
-
-	Disabled .CDFTP macro temporarily for security reasons.
-
-	* tmac/groff_markup.man: Complete revision for latest changes in
-	tmac.arkup -- note that it does not yet format correctly with
-	grohtml :-(

-
-	Fixing a bug which prevented proper end-of-sentence recognition
-	between an `unformatted' box and the following text.  As a
-	consequence, vertical line distances are no longer preserved in
-	boxes after a call to `.unformat' -- because boxes aren't
-	line-oriented (contrary to diversions), this doesn't make sense

-
-2001-02-13  Werner LEMBERG  <wl@gnu.org>
-
-	Redesigned the `unformat' request.  It is no longer connected with
-	`asciify' but rather uses new `reread()' methods if the `unformat'
-	flag is set.  Additionally, the handling of space characters after
-	unformatting has been fixed so that they retain their width.
-
-	* src/roff/troff/node.h (width_list): New structure to store
-	original widths of spaces.
-	(node): Added `unformat' member.

-	`orig_width'.
-	(word_space_node::~word_space_node): New destructor.

-	to handle nodes specially if `unformat' flag is set.
-	(do_asciify_macro): Renamed back to ...
-	(asciify_macro): This.
-	(unformat_macro): New implementation to simply set the `unformat'
-	flag.
-
-	* MORE.STUFF: Added more info about deroff.
-
-2001-02-08  Werner LEMBERG  <wl@gnu.org>
-
-	* src/roff/troff/node.h (unbreakable_space_node, hmotion_node,
-	space_char_hmotion_node, overstrike_node): Add `get_hyphen_list()'
-	and `add_self()' methods to avoid hyphenation.  For example, the
-	hyphen list for `foo\0\0bar' was `foobar', causing insertion of a
-	soft hyphen after `foo'.  Now the hyphen list is correctly
-	`foo<ignore><ignore>bar'.

-	TOKEN_NODE).  This also fixes a hyphenation problem with boxes
-	(after a call to the `unformat' request).

-
-	First cut of the new html device driver.  Changes to pre-html and
-	the new grohtml are too numerous to be documented here.
-
-	Stuff related to `html' has been renamed to `html-old' and `html2'
-	stuff has been renamed to `html' (including directories).  The new
-	html device driver is therefore invoked as `-Thtml'.

-	(`.in', `.fl', etc.) to html driver.

-	Three new functions (.html-begin, .html-end, and .html-image) for
-	better html handling: `html-begin' will execute the remaining line
-	if at the outermost nesting level, increasing an internal counter.
-	`html-end' does the same but decreases the internal counter.
-	`html_image' puts its arguments into a special node (suppress_node)
-	to define an image region.

-	(define_macro_indirect): New function.

-
-2000-09-11  Werner LEMBERG  <wl@gnu.org>
-
-	Implementing two new requests .tm1 and .tmc: The former is similar
-	to .tm but can output leading spaces; its syntax is similar to
-	defining a string, i.e., a `"' can be used to mark the beginning of
-	the string to be written to stderr: `.tm1 " test'.  The latter is
-	similar to .tm1 but doesn't write out a final newline character.

-
-	Redesigning color support in troff.  Colors are no longer

-	space-related nodes, the background color would be changed too late.

-	* src/preproc/eqn/box.cc (box::top_level, box::extra_space): Use
-	`as1' for assigning LINE_STRING (this is `10' usually).  Sun's
-	mm macro package accesses this string register directly.

-2001-10-04  Werner LEMBERG  <wl@gnu.org>
-
-	Implementing color support in troff, pic, grops, and grohtml.  These
-	changes are based on a major patch provided by Gaius Mulley
-	<gaius@glam.ac.uk>.
-
-	New request: `defcolor', supporting rgb, cmy, cmyk, and gray
-	definitions with both hex values and fractions.
-
-	New escapes: \m and \M for drawing and background color,
-	respectively.  This corresponds to the troff output commands `m'
-	and `DF'.
-
-	groff and troff accept command line switch `-c' to disable color
-	output (which is automatically disabled in compatibility mode).
-
-	New scaling indicator `f' for fractions (1f = 65536u).
-
-	New conditional operator `m' to test for defined colors with `if'
-	and `ie'.
-
-	New keywords `color' (or `colour', `colored', `coloured'), `outline'
-	(or `outlined'), and `shaded' added to pic.
-
-	* src/include/color.h: New file.

-		GNU Free Documentation License
-		  Version 1.2, November 2002
-
-
- Copyright (C) 2000,2001,2002  Free Software Foundation, Inc.
-     51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
-0. PREAMBLE
-
-The purpose of this License is to make a manual, textbook, or other
-functional and useful document "free" in the sense of freedom: to
-assure everyone the effective freedom to copy and redistribute it,
-with or without modifying it, either commercially or noncommercially.
-Secondarily, this License preserves for the author and publisher a way
-to get credit for their work, while not being considered responsible
-for modifications made by others.
-
-This License is a kind of "copyleft", which means that derivative
-works of the document must themselves be free in the same sense.  It
-complements the GNU General Public License, which is a copyleft
-license designed for free software.
-
-We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free
-program should come with manuals providing the same freedoms that the
-software does.  But this License is not limited to software manuals;
-it can be used for any textual work, regardless of subject matter or
-whether it is published as a printed book.  We recommend this License
-principally for works whose purpose is instruction or reference.
-
-
-1. APPLICABILITY AND DEFINITIONS
-
-This License applies to any manual or other work, in any medium, that
-contains a notice placed by the copyright holder saying it can be
-distributed under the terms of this License.  Such a notice grants a
-world-wide, royalty-free license, unlimited in duration, to use that
-work under the conditions stated herein.  The "Document", below,
-refers to any such manual or work.  Any member of the public is a
-licensee, and is addressed as "you".  You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-
-A "Modified Version" of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-
-A "Secondary Section" is a named appendix or a front-matter section of
-the Document that deals exclusively with the relationship of the
-publishers or authors of the Document to the Document's overall subject
-(or to related matters) and contains nothing that could fall directly
-within that overall subject.  (Thus, if the Document is in part a
-textbook of mathematics, a Secondary Section may not explain any
-mathematics.)  The relationship could be a matter of historical
-connection with the subject or with related matters, or of legal,
-commercial, philosophical, ethical or political position regarding
-them.
-
-The "Invariant Sections" are certain Secondary Sections whose titles
-are designated, as being those of Invariant Sections, in the notice
-that says that the Document is released under this License.  If a
-section does not fit the above definition of Secondary then it is not
-allowed to be designated as Invariant.  The Document may contain zero
-Invariant Sections.  If the Document does not identify any Invariant
-Sections then there are none.
-
-The "Cover Texts" are certain short passages of text that are listed,
-as Front-Cover Texts or Back-Cover Texts, in the notice that says that
-the Document is released under this License.  A Front-Cover Text may
-be at most 5 words, and a Back-Cover Text may be at most 25 words.
-
-A "Transparent" copy of the Document means a machine-readable copy,
-represented in a format whose specification is available to the
-general public, that is suitable for revising the document
-straightforwardly with generic text editors or (for images composed of
-pixels) generic paint programs or (for drawings) some widely available
-drawing editor, and that is suitable for input to text formatters or
-for automatic translation to a variety of formats suitable for input
-to text formatters.  A copy made in an otherwise Transparent file
-format whose markup, or absence of markup, has been arranged to thwart
-or discourage subsequent modification by readers is not Transparent.
-An image format is not Transparent if used for any substantial amount
-of text.  A copy that is not "Transparent" is called "Opaque".
-
-Examples of suitable formats for Transparent copies include plain
-ASCII without markup, Texinfo input format, LaTeX input format, SGML
-or XML using a publicly available DTD, and standard-conforming simple
-HTML, PostScript or PDF designed for human modification.  Examples of
-transparent image formats include PNG, XCF and JPG.  Opaque formats
-include proprietary formats that can be read and edited only by
-proprietary word processors, SGML or XML for which the DTD and/or
-processing tools are not generally available, and the
-machine-generated HTML, PostScript or PDF produced by some word
-processors for output purposes only.
-
-The "Title Page" means, for a printed book, the title page itself,
-plus such following pages as are needed to hold, legibly, the material
-this License requires to appear in the title page.  For works in
-formats which do not have any title page as such, "Title Page" means
-the text near the most prominent appearance of the work's title,
-preceding the beginning of the body of the text.
-
-A section "Entitled XYZ" means a named subunit of the Document whose
-title either is precisely XYZ or contains XYZ in parentheses following
-text that translates XYZ in another language.  (Here XYZ stands for a
-specific section name mentioned below, such as "Acknowledgements",
-"Dedications", "Endorsements", or "History".)  To "Preserve the Title"
-of such a section when you modify the Document means that it remains a
-section "Entitled XYZ" according to this definition.
-
-The Document may include Warranty Disclaimers next to the notice which
-states that this License applies to the Document.  These Warranty
-Disclaimers are considered to be included by reference in this
-License, but only as regards disclaiming warranties: any other
-implication that these Warranty Disclaimers may have is void and has
-no effect on the meaning of this License.
-
-
-2. VERBATIM COPYING
-
-You may copy and distribute the Document in any medium, either
-commercially or noncommercially, provided that this License, the
-copyright notices, and the license notice saying this License applies
-to the Document are reproduced in all copies, and that you add no other
-conditions whatsoever to those of this License.  You may not use
-technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute.  However, you may accept
-compensation in exchange for copies.  If you distribute a large enough
-number of copies you must also follow the conditions in section 3.
-
-You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-
-
-3. COPYING IN QUANTITY
-
-If you publish printed copies (or copies in media that commonly have
-printed covers) of the Document, numbering more than 100, and the
-Document's license notice requires Cover Texts, you must enclose the
-copies in covers that carry, clearly and legibly, all these Cover
-Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
-the back cover.  Both covers must also clearly and legibly identify
-you as the publisher of these copies.  The front cover must present
-the full title with all words of the title equally prominent and
-visible.  You may add other material on the covers in addition.
-Copying with changes limited to the covers, as long as they preserve
-the title of the Document and satisfy these conditions, can be treated
-as verbatim copying in other respects.
-
-If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-
-If you publish or distribute Opaque copies of the Document numbering
-more than 100, you must either include a machine-readable Transparent
-copy along with each Opaque copy, or state in or with each Opaque copy
-a computer-network location from which the general network-using
-public has access to download using public-standard network protocols
-a complete Transparent copy of the Document, free of added material.
-If you use the latter option, you must take reasonably prudent steps,
-when you begin distribution of Opaque copies in quantity, to ensure
-that this Transparent copy will remain thus accessible at the stated
-location until at least one year after the last time you distribute an
-Opaque copy (directly or through your agents or retailers) of that
-edition to the public.
-
-It is requested, but not required, that you contact the authors of the
-Document well before redistributing any large number of copies, to give
-them a chance to provide you with an updated version of the Document.
-
-
-4. MODIFICATIONS
-
-You may copy and distribute a Modified Version of the Document under
-the conditions of sections 2 and 3 above, provided that you release
-the Modified Version under precisely this License, with the Modified
-Version filling the role of the Document, thus licensing distribution
-and modification of the Modified Version to whoever possesses a copy
-of it.  In addition, you must do these things in the Modified Version:
-
-A. Use in the Title Page (and on the covers, if any) a title distinct
-   from that of the Document, and from those of previous versions
-   (which should, if there were any, be listed in the History section
-   of the Document).  You may use the same title as a previous version
-   if the original publisher of that version gives permission.
-B. List on the Title Page, as authors, one or more persons or entities
-   responsible for authorship of the modifications in the Modified
-   Version, together with at least five of the principal authors of the
-   Document (all of its principal authors, if it has fewer than five),
-   unless they release you from this requirement.
-C. State on the Title page the name of the publisher of the
-   Modified Version, as the publisher.
-D. Preserve all the copyright notices of the Document.
-E. Add an appropriate copyright notice for your modifications
-   adjacent to the other copyright notices.
-F. Include, immediately after the copyright notices, a license notice
-   giving the public permission to use the Modified Version under the
-   terms of this License, in the form shown in the Addendum below.
-G. Preserve in that license notice the full lists of Invariant Sections
-   and required Cover Texts given in the Document's license notice.
-H. Include an unaltered copy of this License.
-I. Preserve the section Entitled "History", Preserve its Title, and add
-   to it an item stating at least the title, year, new authors, and
-   publisher of the Modified Version as given on the Title Page.  If
-   there is no section Entitled "History" in the Document, create one
-   stating the title, year, authors, and publisher of the Document as
-   given on its Title Page, then add an item describing the Modified
-   Version as stated in the previous sentence.
-J. Preserve the network location, if any, given in the Document for
-   public access to a Transparent copy of the Document, and likewise
-   the network locations given in the Document for previous versions
-   it was based on.  These may be placed in the "History" section.
-   You may omit a network location for a work that was published at
-   least four years before the Document itself, or if the original
-   publisher of the version it refers to gives permission.
-K. For any section Entitled "Acknowledgements" or "Dedications",
-   Preserve the Title of the section, and preserve in the section all
-   the substance and tone of each of the contributor acknowledgements
-   and/or dedications given therein.
-L. Preserve all the Invariant Sections of the Document,
-   unaltered in their text and in their titles.  Section numbers
-   or the equivalent are not considered part of the section titles.
-M. Delete any section Entitled "Endorsements".  Such a section
-   may not be included in the Modified Version.
-N. Do not retitle any existing section to be Entitled "Endorsements"
-   or to conflict in title with any Invariant Section.
-O. Preserve any Warranty Disclaimers.
-
-If the Modified Version includes new front-matter sections or
-appendices that qualify as Secondary Sections and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant.  To do this, add their titles to the
-list of Invariant Sections in the Modified Version's license notice.
-These titles must be distinct from any other section titles.
-
-You may add a section Entitled "Endorsements", provided it contains
-nothing but endorsements of your Modified Version by various
-parties--for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-
-You may add a passage of up to five words as a Front-Cover Text, and a
-passage of up to 25 words as a Back-Cover Text, to the end of the list
-of Cover Texts in the Modified Version.  Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or
-through arrangements made by) any one entity.  If the Document already
-includes a cover text for the same cover, previously added by you or
-by arrangement made by the same entity you are acting on behalf of,
-you may not add another; but you may replace the old one, on explicit
-permission from the previous publisher that added the old one.
-
-The author(s) and publisher(s) of the Document do not by this License
-give permission to use their names for publicity for or to assert or
-imply endorsement of any Modified Version.
-
-
-5. COMBINING DOCUMENTS
-
-You may combine the Document with other documents released under this
-License, under the terms defined in section 4 above for modified
-versions, provided that you include in the combination all of the
-Invariant Sections of all of the original documents, unmodified, and
-list them all as Invariant Sections of your combined work in its
-license notice, and that you preserve all their Warranty Disclaimers.
-
-The combined work need only contain one copy of this License, and
-multiple identical Invariant Sections may be replaced with a single
-copy.  If there are multiple Invariant Sections with the same name but
-different contents, make the title of each such section unique by
-adding at the end of it, in parentheses, the name of the original
-author or publisher of that section if known, or else a unique number.
-Make the same adjustment to the section titles in the list of
-Invariant Sections in the license notice of the combined work.
-
-In the combination, you must combine any sections Entitled "History"
-in the various original documents, forming one section Entitled
-"History"; likewise combine any sections Entitled "Acknowledgements",
-and any sections Entitled "Dedications".  You must delete all sections
-Entitled "Endorsements".
-
-
-6. COLLECTIONS OF DOCUMENTS
-
-You may make a collection consisting of the Document and other documents
-released under this License, and replace the individual copies of this
-License in the various documents with a single copy that is included in
-the collection, provided that you follow the rules of this License for
-verbatim copying of each of the documents in all other respects.
-
-You may extract a single document from such a collection, and distribute
-it individually under this License, provided you insert a copy of this
-License into the extracted document, and follow this License in all
-other respects regarding verbatim copying of that document.
-
-
-7. AGGREGATION WITH INDEPENDENT WORKS
-
-A compilation of the Document or its derivatives with other separate
-and independent documents or works, in or on a volume of a storage or
-distribution medium, is called an "aggregate" if the copyright
-resulting from the compilation is not used to limit the legal rights
-of the compilation's users beyond what the individual works permit.
-When the Document is included in an aggregate, this License does not
-apply to the other works in the aggregate which are not themselves
-derivative works of the Document.
-
-If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one half of
-the entire aggregate, the Document's Cover Texts may be placed on
-covers that bracket the Document within the aggregate, or the
-electronic equivalent of covers if the Document is in electronic form.
-Otherwise they must appear on printed covers that bracket the whole
-aggregate.
-
-
-8. TRANSLATION
-
-Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections.  You may include a
-translation of this License, and all the license notices in the
-Document, and any Warranty Disclaimers, provided that you also include
-the original English version of this License and the original versions
-of those notices and disclaimers.  In case of a disagreement between
-the translation and the original version of this License or a notice
-or disclaimer, the original version will prevail.
-
-If a section in the Document is Entitled "Acknowledgements",
-"Dedications", or "History", the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-
-
-9. TERMINATION
-
-You may not copy, modify, sublicense, or distribute the Document except
-as expressly provided for under this License.  Any other attempt to
-copy, modify, sublicense or distribute the Document is void, and will
-automatically terminate your rights under this License.  However,
-parties who have received copies, or rights, from you under this
-License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-
-10. FUTURE REVISIONS OF THIS LICENSE
-
-The Free Software Foundation may publish new, revised versions
-of the GNU Free Documentation License from time to time.  Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.  See
-http://www.gnu.org/copyleft/.
-
-Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License "or any later version" applies to it, you have the option of
-following the terms and conditions either of that specified version or
-of any later version that has been published (not as a draft) by the
-Free Software Foundation.  If the Document does not specify a version
-number of this License, you may choose any version ever published (not
-as a draft) by the Free Software Foundation.
-
-
-ADDENDUM: How to use this License for your documents
-
-To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and
-license notices just after the title page:
-
-    Copyright (c)  YEAR  YOUR NAME.
-    Permission is granted to copy, distribute and/or modify this document
-    under the terms of the GNU Free Documentation License, Version 1.2
-    or any later version published by the Free Software Foundation;
-    with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
-    A copy of the license is included in the section entitled "GNU
-    Free Documentation License".
-
-If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
-replace the "with...Texts." line with this:
-
-    with the Invariant Sections being LIST THEIR TITLES, with the
-    Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
-
-If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-
-If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License,
-to permit their use in free software.

-the files in this directory via patches and a cvs commit.
-
-To upgrade to a newer version of groff, when it is available:
-	1. Unpack the new version into an empty directory.
-	   [Do not make ANY changes to the files.]
-
-	2. Use the command:
-		cvs import -m 'Virgin import of FSF groff v<version>' \

-
-	   For example, to do the import of version 1.19.2, I typed:
-		cvs import -m 'Virgin import of FSF groff v1.19.2' \
-			src/contrib/groff FSF v1_19_2
-
-	3. Follow the instructions printed out in step 2 to resolve any
-	   conflicts between local FreeBSD changes and the newer version.
-
-Do not, under any circumstances, deviate from this procedure.
-
-To make local changes to groff, simply patch and commit to the main
-branch (aka HEAD).  Never make local changes on the FSF branch.
-
-All local changes should be submitted to Werner Lemberg <wl@gnu.org> or

-To install groff, follow the instructions in the file INSTALL.gen.
-
-This file contains information that supplements those instructions.

-
-(For instructions how to build groff with the MinGW tools for
-MS-Windows, see the file README.MinGW.)
-
-groff is written in C++, so you will need a C++ compiler.  The C++
-source files use a suffix of `.cpp', so your C++ compiler must be able
-to handle this.  If you don't already have a C++ compiler, I suggest
-gcc 2.7.1 or later (gcc version 2 includes GNU C++ as well as GNU C).
-From gcc 2.5, it is no longer necessary to install libg++: the C++
-header files needed by groff are created by the gcc installation
-process.  To override configure's choice of C++ compiler, you can set
-the CXX environment variable.
-
-If you have a library that provides a faster malloc than your system's
-usual malloc, it is good idea to include it in LIBS.  For example,
-using the malloc that comes with GNU Emacs version 20 can give a
-worthwhile (and sometimes spectacular) performance improvement.
-
-If you want A4 or letter paper format and the configure script produces
-an incorrect guess, say
-
-  PAGE=xxx ./configure
-
-where `xxx' should be either `A4' or `letter'.  Note that this will only
-affect the paper selection of some device drivers like grops (which can
-be still overridden on the command line).  For compatibility with
-ditroff, the default page length in gtroff is always 11 inches.  The
-page length can be changed with the `pl' request.
-
-When you have built groff, you can use the test-groff script to try
-groff out on one of the man pages.  (Use the .n files not the .man
-files.)  The test-groff script sets up environment variables to allow
-groff to run without being installed.  For example, you could do
-
-  ./test-groff -man -Tascii src/roff/groff/groff.n | less
-
-To get a DVI, PDF, or HTML version of the groff texinfo manual, say `make
-groff.dvi', `make groff.pdf', or `make groff.html', respectively, in the
-`doc' subdirectory (after configuring the groff package).  Note that you
-need texinfo version 4.6 as a prerequisite.  Neither older versions nor
-texinfo 4.7 (due to a bug) will work.
-
-If you have problems, read the PROBLEMS file.  If this doesn't help
-send a bug report using the form in the file BUG-REPORT.

-Installation Instructions
-*************************
-
-Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004 Free
-Software Foundation, Inc.
-
-This file is free documentation; the Free Software Foundation gives
-unlimited permission to copy, distribute and modify it.
-
-Basic Installation
-==================
-
-These are generic installation instructions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  (Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.)
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You only need
-`configure.ac' if you want to change it or regenerate `configure' using
-a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes awhile.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-Compilers and Options
-=====================
-
-Some systems require unusual options for compilation or linking that the
-`configure' script does not know about.  Run `./configure --help' for
-details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   If you have to use a `make' that does not support the `VPATH'
-variable, you have to compile the package for one architecture at a
-time in the source code directory.  After you have installed the
-package for one architecture, use `make distclean' before reconfiguring
-for another architecture.
-
-Installation Names
-==================
-
-By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PREFIX'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-give `configure' the option `--exec-prefix=PREFIX', the package will
-use PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-There may be some features `configure' cannot figure out automatically,
-but needs to determine by the type of machine the package will run on.
-Usually, assuming the package is built to be run on the _same_
-architectures, `configure' can figure that out, but if it prints a
-message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the `--target=TYPE' option to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-If you want to set default values for `configure' scripts to share, you
-can create a site shell script called `config.site' that gives default
-values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-will cause the specified gcc to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-`configure' Invocation
-======================
-
-`configure' recognizes the following options to control how it operates.
-
-`--help'
-`-h'
-     Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to
-     disable caching.
-
-`--config-cache'
-`-C'
-     Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.

-driver).  The actual version can be found as
-
-  ftp://ftp.ffii.org/pub/groff/plot2dev-x.x.tar.gz
-
-troffcvt
---------
-
-From the web page:
-
-  troffcvt is a translator that turns troff input into a form that can be
-  more easily processed.  The troffcvt distribution comes with
-  postprocessors that turn troffcvt into various destination formats such
-  as HTML (Hypertext Markup Language), RTF (Rich Text Format) or plain
-  text.
-
-Note that you need a lot of additional packages to compile troffcvt;
-everything is available from
-
-  http://www.primate.wisc.edu/software/troffcvt/
-
-unroff
-------
-
-From the README file:
-
-  Unroff is a Scheme-based, programmable, extensible troff translator with
-  a back-end for the Hypertext Markup Language.  Unroff is free software
-  and is distributed both as source and as precompiled binaries.
-
-    http://www.informatik.uni-bremen.de/~net/unroff/unroff.html

-miscellaneous
--------------
-
-. Ralph Corderoy's excellent page on troff:
-
-    www.troff.org
-
-  There are links for virtually everything related to troff.
-
-. Dr. Robert Hermann's groff gems are available from
-
-    http://www.eas.slu.edu/People/RBHerrmann/GROFF/index.html
-
-  At present there are examples for
-
-  o creating business cards
-  o using groff to make large format posters for presentations
-
-. Robert Marks's collection of useful macros and scripts is available from
-
-    http://www.agsm.edu.au/~bobm/odds+ends/scripts.html
-
-  Description:
-
-  o `polish': Is a sed (= the Unix stream editor) script that does many
-    things to ASCII text.  Amongst other things, it breaks lines at new
-    sentences, reduces upper-case acronyms by one point size, adds
-    diacriticals, changes simple quotes into smart quotes, and makes a few
-    simple grammar checks.  The best way to see what it does is to run it
-    as a sed script file (or files) on a text file and then compare the
-    output file with the original.
-
-  o `DropCaps' is a troff script which replaces the initial letters of
-    paragraphs immediately after H1 and H2 headings with drop-capitals of
-    specified point size, and automatically flows the text around the new
-    drop cap.
-
-  o `AJM Header' is a set of troff macros used in production of the
-    Australian Journal of Management.  They use the Memorandum Macros (mm)
-    of AT&T, and so should be invoked with the UNIX troff -mm flag; they
-    should also work with the GNU troff -mm flag.
-
-. Thomas Baruchel <baruchel@libertysurf.fr> has developed Meta-tbl, a tbl
-  postprocessor to manipulate table cells (like adding gray shades).  The
-  latest version can be found at
-
-    http://perso.libertysurf.fr/baruchel/
-
-. gpresent, written by Bob Diertens <bobd@science.uva.nl>.  From the README
-  file:
-
-    gpresent is a package for making presentation with groff and acroread.
-    It consist of a set of macros to be used with groff and a post-processor
-    for manipulating the PostScript output of groff.  Without the use of the
-    PAUSE macro, it can also be used for making slides.
-    
-  It is available from
-

-This file describes recent user-visible changes in groff.  Bug fixes are not
-described.  There are more details in the man and info pages.
-
-VERSION 1.19.2
-==============
-
-Troff
------
-
-o Analogously to the .ft and \f pair, two new requests `gcolor' and
-  `fcolor' (which pair with \m and \M, respectively) have been added to
-  set the glyph and background colours.
-
-o A new read-only, string-valued register `.sty' returns the name of the
-  current style.
-
-o Two new conditional operators `F <name>' and `S <name>' have been added.
-  `F' is true if a font <name> exists.  `S' is true if a style <name> has
-  been registered.
-
-o Cyrillic characters have been added to the `utf8' and `html' output
-  devices.
-
-Pic
----
-
-o The `by' argument in a `for' loop can now be negative if it is additive.
-  For the multiplicative case, it must be greater than zero.
-
-Eqn
----
-
-o The following keywords aren't new but haven't been documented previously:
-
-    undef NAME    (to undefine a macro)
-    copy  "FILE"  (a synonym for `include')
-    space n       (to modify the vertical spacing before and after
-                   an equation)
-
-o The following macros aren't new but haven't been documented previously:
-
-    Alpha, ..., Omega   (the same as `ALPHA', ..., `OMEGA')
-    ldots               (three dots on the base line)
-    dollar              (a dollar glyph)
-
-o The following keywords have been extended.  Again, this isn't new but
-  hasn't been documented previously:
-
-    col n { ... }
-    lcol n { ... }
-    rcol n { ... }
-    ccol n { ... }
-    pile n { ... }
-    lpile n { ... }
-    rpile n { ... }
-    cpile n { ... }   (set vertical spacing between rows to N)
-
-Grohtml
--------
-
-o This device driver has been raised to beta stage; its set of tags should
-  be stable now.
-
-o New command line option `-s' to set the base point size.
-
-o New command line option `-S' to set the split level while generating
-  multiple files.
-
-Grotty
-------
-
-o Experimental support for zero-width and double-width characters.
-  
-Gxditview
----------
-
-o On platforms which have the X Window System this program is now built and
-  installed automatically.
-
-Xtotroff
---------
-
-o This program to create font definition files for xditview isn't new but
-  hasn't been installed previously.
-
-Groffer
--------
-
-o A security problem (reported as CAN-2004-0969) has been fixed.
-
-Gdiffmk
--------
-
-o A new script contributed by Mike Bianchi.  It compares two groff, nroff,
-  or troff documents and creates an output with added margin characters
-  (using `.mc') to indicate the differences.
-
-Pdfroff
--------
-
-o A new wrapper script contributed by Keith Marshall to easily create PDF
-  documents with groff.
-
-Macro packages
---------------
-
-o ms.tmac
-
-  . Support for fractional point sizes: A value for the `PS', `VS', `FPS',
-    and `VPS' register larger than or equal to 1000 is always divided by
-    1000.  For example, `.nr PS 10250' sets the document's font size to
-    10.25 points.
-
-  . The `Ds' and `De' macros provided in ms since groff version 1.19 have
-    been removed; the equivalent `DS' and `DE' macros should be used
-    instead.  X11 documents which actually use `Ds' and `De' always load a
-    specific macro file from the X11 distribution (`macros.t') which
-    provides proper definitions for the two macros.
-
-  . The following registers have been added for improving layout control:
-
-    PORPHANS
-      Defines number of lines following `LP', `PP', `QP', `IP' or `XP' which
-      must be kept together, before any automatic page break.
-
-    HORPHANS
-      Sets number of lines of following paragraph which must be kept with a
-      heading, defined by `NH' or `SH', before any automatic page break.
-
-    GROWPS
-      Sets the first level of heading (set with `NH') which will keep the
-      same point size as body text.
-
-    PSINCR
-      Sets the point size increment for each level of heading (set with
-      `NH'), below the threshold level set by `GROWPS'; e.g., if
-      \n[PS] = 10, \n[GROWPS] = 3 and \n[PSINCR] = 2.0p, then `.NH 1' will
-      produce 14pt headings, `.NH 2' will produce 12pt, and all other levels
-      will remain at 10pt (because \n[PS] = 10).
-
-  . The `SH' macro now accepts a numeric argument, to make heading size
-    match that of `NH' with same argument value when the `GROWPS'/`PSINCR'
-    feature is enabled.
-
-  Please refer to the documentation of the ms package for other, minor
-  improvements.
-
-o me.tmac
-
-  The section type set with the `++' request is available in the `_M'
-  register.  This isn't new but hasn't been documented before.
-
-o www.tmac
-
-  The `HR' macro no longer causes an empty line for non-HTML devices.
-
-  A new macro `HEAD' has been added to directly add data to the
-  <head>...</head> block.
-
-  New macros `OLS' and `OLE' to start and end an ordered list.
-
-  New macros `DLS' and `DLE' to start and end a definition list.
-
-Pdfmark
--------
-
-o A new macro package contributed by Keith Marshall which implements PDF
-  marks.  This is in alpha stage currently.
-
-Miscellaneous
--------------
-
-o Two new keywords to the DESC file have been added which are needed for
-  grohtml: `image_generator' and `unscaled_charwidths'.  The former gives
-  the name of the program which creates PNG images, and the latter makes
-  troff always use unscaled character widths.
-
-
-VERSION 1.19.1
-==============
-
-Groff
------
-
-o The argument of the command line option `-I' is now also passed to troff
-  and grops, specifying a directory to search for files on the command line,
-  files named in `so' and `psbb' requests, and files named in \X'ps: file'
-  and \X'ps: import' escapes.
-
-o If option `-V' is used more than once, the commands will be both printed
-  on standard error and run.
-
-Troff
------
-
-o Two new read-only, string-valued registers `.m' and `.M' return the
-  name of the current drawing and background color, respectively.
-
-o New read-only register `.U' which is set to 1 if in safer mode and set
-  to 0 if in unsafe mode.
-
-o An input encoding file for latin-5 (a.k.a. ISO 8859-9) has been added.
-  Example use:
-
-    groff -Tdvi -mlatin5 my_file > my_file.dvi
-
-  Note that some output devices don't support all glyphs of this encoding.
-
-o If the `return' request is called with an argument, it exits twice,
-  namely the current macro and the macro one level higher.  This is
-  used to define a wrapper macro for `return' in trace.tmac.
-
-o For completeness, two new requests have been added: `dei1' and `ami1'.
-  They are equivalent to `dei' and `ami', respectively, but the macros
-  are executed with compatibility mode off (similar to `de1' and `am1').
-
-o New command line option `-I' to specify a directory for files (both
-  those on the command line and those named in `psbb' requests).  This is
-  also handled by the groff wrapper program.
-
-o Since version 1.19 you can say `.vs 0'.  Older versions emit a warning
-  and convert this to `.vs \n[.V]'.
-
-  This hasn't been documented properly.  Note that `.vs 0' isn't saved in a
-  diversion since it doesn't result in vertical motion.
-
-Pic
-___
-
-o Dashed and dotted ellipses have been implemented.
-
-Tbl
----
-
-o New key character `x' to make tbl call a user-defined macro on a table
-  cell.  Patch by Heinz-Jürgen Oertel <hj.oertel@surfeu.de>.
-
-Grap2graph
-----------
-
-o A new script contributed by Eric S. Raymond <esr@thyrsus.com>.  It
-  converts a grap diagram into a cropped image.  Since it uses gs and the
-  PNM library, virtually all graphics formats are available for output.
-  [Note that the grap program itself isn't part of the groff package;
-  see the file MORE.STUFF how to obtain grap.]
-
-Grohtml
--------
-
-o New option `-j' to emit output splitted into multiple files.
-
-Grops
------
-
-o New command line option `-I' to specify a directory to search for files
-  on the command line and files named in \X'ps: import' and \X'ps: file'
-  escapes.  This is also handled by the groff wrapper program.
-
-o The default value for the `broken' keyword in the DESC file is now 0.
-
-Grolj4
-------
-
-o A new man page `lj4_font(5)' documents how fonts are accessed with
-  grolj4.
-
-o The built-in fonts for LJ4 and newer PCL 5 devices have been completely
-  revised, mainly to access as much glyphs as possible.  The provided
-  metric files should be compatible with recent PCL 5 printers also.
-  Additionally, font description files have been added for the Arial and
-  Times New Roman family, the MS symbol, and Wingdings fonts.
-
-Afmtodit
---------
-
-o New option `-x' to prevent use of built-in Adobe Glyph List.
-
-Hpftodit
---------
-
-o Completely revised to handle HP TrueType metric files also.  See the
-  hpftodit manual page for more details.
-
-Groffer
--------
-
-o This version is a rewrite of groffer in many parts, but it is kept in
-  the old single script style.
-
-  New options: --text, --mode text, --tty-viewer, --X, --mode X,
-  --X-viewer, --html, --mode html, --html-view, --apropos-data,
-  --apropos-devel, --apropos-progs.
-
-  New documentation file: README_SH.
-
-  Enhancement of the configuration files and the `apropos' handling.
-
-Macro Packages
---------------
-
-o www.tmac: New macro `JOBNAME' to split output into multiple files.
-
-o In mdoc, multiple calls to `.Lb' are now supported in the LIBRARY
-  section.
-
-
-VERSION 1.19
-============
-
-Troff
------
-
-o Input encoding files for latin-9 (a.k.a. latin-0 and ISO 8859-15) and
-  latin-2 (ISO 8859-2) have been added.  Example use:
-
-    groff -Tdvi -mlatin9 my_file > my_file.dvi
-
-  You still need proper fonts with the necessary glyphs.  Out of the box,
-  the groff package supports latin-9 only for -Tps, -Tdvi, and -Tutf8,
-  and latin-2 only for -Tdvi and -Tutf8.
-
-o Composite glyphs are now supported.  To do this, a subset of the Adobe
-  Glyph List (AGL) Algorithm as described in
-
-    http://partners.adobe.com/asn/tech/type/unicodegn.jsp
-
-  is used to construct glyph names based on Unicode character codes.  The
-  existing groff glyph names are frozen; no glyph names which can't be
-  constructed algorithmically will be added in the future.
-
-  The \[...] escape sequence has been extended to specify multiple glyph
-  components.  Example:
-
-    \[A ho]
-
-  this accesses a glyph with the name `u0041_0328'.
-
-  Some groff glyphs which are useful as composites map to `wrong' Unicode
-  code points.  For example, `ho' maps to U+02DB which is a spacing
-  ogonek, whereas a non-spacing ogonek U+0328 is needed for composite
-  glyphs.  The new request
-
-    .composite from to
-
-  will change the mapping while a composite glyph name is constructed.
-  To make \[A ho] yield the expected result,
-
-    .composite ho u0328
-
-  is needed.  [The new file `composite.tmac' loaded at start-up already
-  contains proper calls to `.composite'.]
-
-  Please refer to the info pages of groff and to the groff_char man page
-  for more details.
-
-o A new request `fschar' has been added to define font-specific fallback
-  characters.  They are searched after the list of fonts declared with the
-  `fspecial' request but before the list of fonts declared with `special'.
-
-o Fallback characters defined with `fschar' can be removed with the
-  new `rfschar' request.
-
-o A new request `schar' has been added to define global fallback
-  characters.  They are searched after the list of fonts declared with the
-  `special' request but before the already mounted special fonts.
-
-o In groff versions 1.18 and 1.18.1, \D'f ...' didn't move the current
-  point horizontally.  Despite of being silly, this change has been
-  reverted for backwards compatibility.  Consequently, the intermediate
-  output command `Df' also moves the position horizontally again.
-
-  \D'f ...' is deprecated since it depends on the horizontal resolution of
-  the output device (given with the `hor' parameter in the DESC file).
-  Use the new \D'Fg ...' escape instead.
-
-o For orthogonality, new \D subcommands to change the fill color are
-  available:
-
-    \D'Fr ...' (rgb)
-    \D'Fc ...' (cmy)
-    \D'Fg ...' (gray)
-    \D'Fk ...' (cmyk)
-    \D'Fd'     (default color)
-
-  The arguments are the same as with the `defcolor' request.  The current
-  position is *not* changed.
-
-o The values set with \H and \S are now available in number registers
-  \n[.height] and \n[.slant], respectively.
-
-o The `.pe' number register isn't new but hasn't been documented before.
-  It is set to 1 during a page ejection caused by the `bp' request.
-
-o The new glyph symbol `tno' is a textual variant of `no'.
-
-o The new glyph symbol `+e' represents U+03F5, GREEK LUNATE EPSILON SYMBOL.
-  (Well, it is not really new since it has been previously supported by
-  grolj4.)  The mapping for both the dvi and lj4 symbol font has been
-  changed accordingly so that Greek small letter epsilon, `*e', has the
-  same glyph shape as with other devices.
-
-Grops
------
-
-o The font `freeeuro.pfa' has been added to provide various default glyph
-  shapes for `eu' and `Eu'.
-
-o It is now possible to access all glyphs in a Type 1 font, not only 256
-  (provided the font file created by afmtodit has proper entries).  grops
-  constructs additional encoding vectors on the fly if necessary.
-
-o The paper size is now emitted via the %%DocumentMedia and PageSize
-  mechanisms so that it is no longer required to tell `gv' or `ps2pdf'
-  about the paper size.  The `broken' flag value 16 omits this feature
-  (the used PostScript command `setpagedevice' is a LanguageLevel 2
-  extension) -- if you intend to further process grops output to get an
-  encapsulated PS (EPS) file you must also use this option.
-
-  Patch by Egil Kvaleberg <egil@kvaleberg.no>.
-
-o Non-slanted PostScript metrics have been changed again; they no longer
-  contain negative left italic correction values.  This assures correct
-  spacing with eqn.
-
-Grodvi
-------
-
-o The font cmtex10 has been added as the special font `SC' to the DVI fonts.
-  It is used as a font-specific special font for CW and CWI.
-
-o New options -l and -p to set landscape orientation and the paper size.
-  grodvi now emits a `papersize' special which is understood by DVI drivers
-  like dvips.
-
-  Consequently, the DESC file should contain a `papersize' keyword.
-
-o The glyph shapes for \[*f] and \[*e] have been exchanged with \[+f] and
-  \[+e], respectively, to be in sync with all other devices.
-
-o Glyphs \[HE] and \[DI] have been replaced with \[u2662] and \[u2661],
-  respectively, since the former two glyphs have a black (filled) shape
-  which grodvi doesn't provide by default (it never has actually).
-
-Grolj4
-------
-
-o The glyphs \[*e] and \[+e] have been exchanged to be in sync with
-  all other devices.
-
-o The glyph \[~=] is now called \[|=].  Similar to other devices, \[~=]
-  is now another name for glyph \[~~].
-
-Grotty
-------
-
-o New option `-r'.  It is similar to the -i option except it tells grotty to
-  use the `reverse video' attribute to render italic fonts.
-
-Pic
----
-
-o New command `figname' to set the name of a picture's output box in TeX
-  mode.
-
-Refer
------
-
-o The environment variable `REFER' to override the name of the default
-  database isn't new but hasn't been documented before.
-
-Soelim
-------
-
-o New option `-r' to avoid emission of `.lf' lines.
-
-o New option `-t' to emit TeX comment lines (giving current file and the
-  line number) instead of `.lf' lines.
-
-Afmtodit
---------
-
-o Unencoded glyphs in an AFM file are output also (since grops can now emit
-  multiple encoding vectors for a single font).
-
-o New option `-m' to prevent negative left italic correction values.
-
-o The mapping and encoding file together with file `DESC' are now searched
-  in the default font directory also.  Please refer to the man page of
-  afmtodit for more details.
-
-Macro Packages
---------------
-
-o Larry Kollar <kollar@alltel.net> and others made the man macros more
-  customizable.
-
-  . New command line options -rFT, -rIN, and -rSN to set the vertical
-    location of the footer line, the body text indentation, and the
-    sub-subheading indentation.
-
-  . New command line option -rHY (similar to the ms macros) to control
-    hyphenation.
-
-  . New macros `.PT' and `.BT' to print the header and footer strings.
-    They can be replaced with a customized version in `man.local'.
-
-  . The string `HF' now holds the typeface to print headings and
-    subheadings.
-
-  . Similar to the ms macros, the LT register now defaults to LL if not
-    explicitly specified on the command line.
-
-o troff's start-up file `troffrc' now includes `papersize.tmac' to set
-  the paper size with the command line option `-dpaper=<size>'.
-
-  Possible values for `<size>' are the same as the predefined `papersize'
-  values in the DESC file (only lowercase; see the groff_font man page)
-  except a7-d7.  An appended `l' (ell) character denotes landscape
-  orientation.  Examples: `a4', `c3l', `letterl'.
-
-  Most output drivers need additional command line switches `-p' and
-  `-l' to override the default paper length and orientation as set in
-  the driver specific DESC file.
-
-  For example, use the following for PS output on A4 paper in landscape
-  orientation:
-
-    groff -Tps -dpaper=a4l -P-pa4 -P-l -ms foo.ms > foo.ps
-
-
-VERSION 1.18.1
-==============
-
-Troff
------
-
-o The non-slanted PostScript font definition files have been regenerated to
-  include left and right italic correction values.  Applying those to a
-  glyph (this is, prepending the glyph with `\,' and appending `\/' to the
-  glyph) sets the glyph width to the real value given by the horizontal
-  bounding box values.  Without those escapes, the advance width for the
-  particular glyph is used (which can differ considerably).
-
-  Most users will neither need this feature nor notice a difference in
-  existing documents (provided \, and \/ is used as advertised, namely for
-  italic fonts only); its main goal is to improve image generation with
-  grohtml.
-
-  This is an experimental change, and feedback is welcome.
-
-Tbl
----
-
-o Added global option `nospaces' to ignore leading and trailing spaces in
-  data items.
-
-Grolbp
-------
-
-o The option -w (--linewidth) has been added (similar to other device
-  drivers) to set the default line width.
-
-Grn
----
-
-o Support for b-spline and Bezier curves has been added.
-
-Groffer
--------
-
-o New option `--shell' to select the shell under which groffer shall run.
-
-Macro Packages
---------------
-
-o The string `Am' (producing an ampersand) has been added to mdoc for
-  compatibility with NetBSD.
-
-o `.IX' is now deprecated for mom; you should use `.IQ' (Indent Quit)
-  instead.
-
-o In mom, new inlines `FWD', `BCK', `UP', and `DOWN' deal with horizontal
-  and vertical movements; please refer to contrib/mom/NEWS for more
-  details.
-
-o New macro ENDNOTES_HDRFTR_CENTER for mom to better control headers.
-
-Miscellaneous
--------------
-
-o The `papersize' keyword in the DESC file now accepts multiple arguments.
-  It is scanned from left to the right, and the first valid argument is
-  used. This makes it possible to provide a fallback paper size.
-
-  Example:
-
-    papersize /etc/papersize a4
-
-o A local font directory has been prepended to the default font path; it
-  defaults to /usr/local/share/groff/site-font.  Similar to the normal
-  font searching process, files must be placed into a devXXX subdirectory,
-  e.g.
-
-    /usr/local/share/groff/site-font/devps/FOO
-
-  for a PostScript font definition file FOO.

-
-Troff
------
-
-o Color support has been added to troff and pic (and to the device drivers
-  grops, grodvi, grotty, and grohtml -- other preprocessors and drivers will
-  follow).  A new function `defcolor' defines colors; the escape sequence
-  `\m' sets the drawing color, the escape sequence `\M' specifies the
-  background color for closed objects created with \D'...' commands.
-  `\m[]' and `\M[]' switch back to the previous color.  `\m' and `\M'
-  correspond to the new troff output command sets starting with `m' and
-  `DF'.  The device-specific default color is called `default' and can't be
-  redefined.
-
-  Use the `color' request to toggle the usage of colors (default is on); the
-  read-only register `.color' is 0 if colors are not active, and non-zero
-  otherwise.
-
-  The old `Df' output command is mapped onto `DFg'; all color output
-  commands don't change the current font position (consequently, `Df'
-  doesn't either).
-
-  Outputting color can be disabled in troff and groff with the option -c
-  (it is always disabled in compatibility mode).  See the section on grotty
-  for the GROFF_NO_SGR environment variable also.
-
-  For defining color components as fractions between 0 and 1, a new scaling
-  indicator `f' has been introduced: 1f = 65536u.  For testing whether a
-  color is defined (with .if and .ie), a new conditional operator `m' is
-  available.
-
-  More details can be found in the groff_diff.7 manual page and in
-  groff.texinfo.
-
-o Similar to \m and \M, \f[] switches back to the previous font.  \fP
-  (and \f[P]) is still valid for backwards compatibility.
-
-o The new escape \F is the same as `.fam'; \F[] switches back to previous
-  family -- \F[P] selects family `P'.
-
-o Two new glyph symbols are available: `eu' is the official Euro symbol;
-  `Eu' is a font-specific glyph variant.
-
-o The new glyph symbols `t+-', `tdi', and `tmu' are textual variants of
-  `+-', `di', and `mu', respectively.
-
-o Latin-1 character 181 (PS name `mu', Unicode name U+00B5 MICRO SIGN) has
-  got the troff glyph name `mc'.
-
-o -Tutf8 is now available on EBCDIC hosts.
-
-o Strings can take arguments, using this syntax: \*[foo arg1 arg2 ...].
-  Example:
-
-    .ds xxx This is a \\$1 test.
-    \*[xxx nice]
-
-o It is now possible to have whitespace between the first and second dot (or
-  the name of the ending macro) to end a macro definition.  Example:
-
-    .de !
-    ..
-    .
-    .de foo
-    .  nop Hello, I'm `foo'.
-    .  nop I will now define `bar'.
-    .  de bar !
-    .    nop Hello, I'm `bar'.
-    .  !
-    ..
-
-o `.fn' is a new string-valued register which returns the (internal) real
-  font name; styles and families are properly concatenated.
-
-o Three new read/write registers `seconds', `minutes', and `hours' contain
-  the current time, set at start-up of troff.  Use the `af' request to
-  control their output format.
-
-o The new request `fchar' can be used to provide fallback characters.  It
-  has the same syntax as the `char' request; the only difference is that a
-  character defined with `.char' hides the glyph with the same name in the
-  current font, whereas a character defined with `.fchar' is checked only if
-  the particular glyph isn't found in the current font.  This test happens
-  before checking special fonts.
-
-o In analogy to the `tmc' request, `.writec' is the same as `.write' but
-  doesn't emit a final newline.
-
-o The new request `itc' is a variant of `.it' for which a line interrupted
-  with \c counts as one input line.
-
-o Two new requests `ds1' and `as1' which are similar to `ds' and `as' but
-  with compatibility mode disabled during expansion of strings defined by
-  them.
-
-o The syntax of the `substring' request has been changed: The first
-  character in a string now has index 0, the last character has index -1.
-  Note that this is an incompatible change.
-
-o To emit strings directly to the intermediate output, a new `output'
-  request has been added; it is similar to `\!' used at the top level.
-
-o `.hpf' has been extended.  It can now handle most TeX hyphenation
-  pattern files without modification.  To do that, the commands \patterns,
-  \hyphenation, and \endinput are recognized.  Please refer to groff_diff.7
-  for more information.
-
-o `hpfcode' is a new request to provide an input encoding mapping for the
-  `hpf' request.
-
-o The new request `hpfa' appends hyphenation patterns (`hpf' replaces
-  already existing patterns).
-
-o A new request `ami' (append macro indirect) has been added.  The first and
-  second parameter of `ami' are taken from string registers rather than
-  directly; this very special request is needed to make `trace.tmac'
-  independent from the escape character (which might even be disabled).
-
-o The new request `sizes' is similar to the `sizes' command in DESC files.
-  It expects the same syntax; the data must be on a single line, and the
-  final `0' can be omitted.
-
-o `trin' (translate input) is a new request which is similar to `tr' with
-  the exception that the `asciify' request will use the character code (if
-  any) before the character translation.  Example:
-
-    .trin ax
-    .di xxx
-    a
-    .br
-    .di
-    .xxx
-    .trin aa
-    .asciify xxx
-    .xxx
-
-  The result is `x a'.  Using `tr', the result would be `x x'.
-
-o The request `pvs' isn't new, but hasn't been documented before.  It
-  adds vertical space after a line has been output.  This makes it an
-  alternative to the `ls' request to produce double-spaced documents.
-  The read-only register `.pvs' holds the current amount of the
-  post-vertical line space.
-
-o For compatibility with plan 9's troff, multiple `pi' requests are
-  supported:
-
-    .pi foo
-    .pi bar
-
-  is now equivalent to
-
-    .pi foo | bar
-
-o A new escape sequence `\O' is available to disable and enable glyph
-  output.  Please see groff_diff.7 and groff.texinfo for more details.
-
-o The escapes `\%', `\&', `\)', and `\:' no longer cause an error in \X;
-  they are ignored now.  Additionally `\ ' and `\~' are converted to
-  single space characters.
-
-o The default tab distance in nroff mode is now 0.8i to be compatible
-  with UNIX troff.
-
-o Using the latin-1 input character 0xAD (soft hyphen) for the `shc'
-  request was a bad idea.  Instead, it is now translated to `\%', and
-  the default hyphenation character is again \[hy].  Note that the glyph
-  \[shc] is not useful for typographic purposes; it only exists to have
-  glyph names for all latin-1 characters.
-
-Macro Packages
---------------
-
-o Peter Schaffter <df191@ncf.ca> has contributed a new major macro package
-  called `mom', mainly for non-scientific writers, which takes care of
-  many typographic issues.  It comes with a complete reference (in HTML
-  format) and some examples.  `mom' has been designed to format documents
-  for PostScript output only.
-
-o Two macros `AT' (AT&T) and `UC' (Univ. of California) have been added to
-  the man macros for compatibility with older BSD releases.
-
-o Both the man and mdoc macro packages now use the LL and LT registers for
-  setting the line and title length, respectively (similar to those
-  registers in the ms macro package).  If not set on the command line or
-  in a macro file loaded before the macro package itself, they default to
-  78n in nroff mode and 6.5i in troff mode.
-
-o The `-xwidth' specifier in the mdoc macro package has been removed.  Its
-  functionality is now integrated directly into `-width'.  Similarly,
-  `-column' has been extended to provide this functionality also.
-
-o A new macro `Ex' has been added to the mdoc macro package to document an
-  exit status.
-
-o The PSPIC macro has been extended to work with DVI output (`pspic.tmac' is
-  now automatically loaded for -Tdvi), using a dvips special to load the EPS
-  file.
-
-o The trace.tmac package now traces calls to `am' also.  Additionally, it
-  works in compatibility mode.
-
-o `troff.1' has been split.  Differences to UNIX troff are now documented
-  in the new man page `groff_diff.7'.
-
-o `groff_mwww.7' has been renamed to `groff_www.7'.  The file mwww.tmac
-  has been removed.
-
-o `groff_ms.7' has been completely rewritten.  It now contains a complete
-  reference to the ms macros.
-
-o `groff_trace.7' documents the trace macro package.
-
-o Changes in www.tmac:
-
-    Note that HTML support is still in alpha change, so it is rather likely
-    that both macro names and macro syntax will change.  Some of the macros
-    mentioned below aren't really new but haven't been documented properly
-    before.
-
-    The following macros have been renamed:
-
-        MAILTO     -> MTO
-        IMAGE      -> IMG
-        LINE       -> HR
-
-    For consistency, the macros `URL', `FTL', and `MTO' now all have the
-    address as the first parameter followed by the description.
-
-    By default, grohtml generates links to all section headings at the top
-    of the document.  Use the new `LK' macro to specify a different place.
-
-    For specifying the background color and a background image, use the
-    new macros `BCL' and `BGIMG', respectively.
-
-    The macro `NHR' has been added; it suppresses the generation of top and
-    bottom rules which grohtml emits by default.
-
-    The new macro `HX' determines the cut-off point for automatic link
-    generation to headings.
-
-    The image position parameter names in `IMG' have been changed to `-L',
-    `-R', and `-C'.
-
-    New macro `PIMG' for inclusion of a PNG image (it will automatically
-    convert it into an EPS file if not -Thtml is used).
-
-    New macro `MPIMG' for putting a PNG image into the left or right margin
-    (it will automatically convert it into an EPS file if not
-    -Thtml is used).
-
-    New macros `HnS', `HnE' to start and end a header line block.
-
-    New macro `DC' to produce dropcap characters.
-
-    New macro `HTL' to generate an HTML title line only but no H1 heading.
-
-    New macros `ULS' and `ULE' to start and end an unordered list.  The new
-    macro `LI' inserts a list item.
-
-Groff
------
-
-o The new command line option `-c' disables color output (which is always
-  disabled in compatibility mode).
-
-Nroff
------
-
-o Two new command line options `-c' and `-C'; the former passes `-c' to
-  grotty (switching to the old output scheme); the latter passes `-C' to
-  groff (enabling compatibility mode).
-
-Pic
----
-
-o New keywords `color' (or `colour', `colored', `coloured'), `outline' (or
-  `outlined'), and `shaded' are available.  `outline' sets the color of the
-  outline, `shaded' the fill color, and `color' sets both.  Example:
-
-    circle shaded "green" outline "black" ;
-
-  Filled arrows always use the outline color for filling.
-
-  Color support for TeX output is not implemented yet.
-
-Pic2graph
----------
-
-o A new script contributed by Eric S. Raymond <esr@thyrsus.com>.  It
-  converts a PIC diagram into a cropped image.  Since it uses gs and the PNM
-  library, virtually all graphics formats are available for output.
-
-Eqn2graph
----------
-
-o A new script contributed by Eric S. Raymond <esr@thyrsus.com>.  It
-  converts an EQN diagram into a cropped image.  Since it uses gs and the PNM
-  library, virtually all graphics formats are available for output.
-
-Groffer
--------
-
-o A new script contributed by Bernd Warken <bwarken@mayn.de>.  It displays
-  groff files and man pages on X and tty, taking care of most parameters
-  automatically.
-
-Grog
-----
-
-o Documents using the mom macro package are recognized.
-
-Grops
------
-
-o Color support has been added.
-
-o A new option `-p' is available to select the output paper size.  It has
-  the same syntax as the new `papersize' keyword in the DESC file.
-
-Grodvi
-------
-
-o By default, font sizes are now available in the range 5-10000pt, similar
-  to PS fonts. If you want the old behaviour (i.e., font sizes at discrete
-  values only), insert the following at the start of your document:
-
-    .if '\*[.T]'dvi' \
-    .  sizes 500 600 700 800 900 1000 1095 1200 1400 1440 1600 \
-             1728 1800 2000 2074 2200 2400 2488 2800 3600
-
-o A new font file HBI (using cmssbxo10; this is slanted sans serif bold
-  extended) has been added.
-
-o Two font families are now available: `T' and `H'.
-
-o EC and TC fonts have been integrated.  Use `-mec' (calling the file
-  ec.tmac) to switch to them.  Those fonts give a much better coverage of
-  the symbols defined by groff than the CM fonts.
-
-  Note that ec.tmac must be called before any language-specific files; it
-  doesn't take care of hcode values.
-
-o Color support has been added.  For drawing commands, colors are translated
-  to gray values currently.
-
-Grotty
-------
-
-o Color support has been added, using the SGR (ISO 6429, sometimes called
-  ANSI color) escape sequences.
-
-o SGR escape sequences are now used by default for underlining and bold
-  printing also, no longer using the backspace character trick.  To revert
-  to the old behaviour, use the `-c' switch.
-
-  Note that you have to use the `-R' option of `less' to make SGR escapes
-  display correctly.  On the other hand, terminal programs and consoles like
-  `xterm' which support SGR sequences natively can directly display the
-  output of grotty.  Consequently, the options `-b', `-B', `-u', and `-U'
-  work only in combination with `-c' and are ignored silently otherwise.
-
-  For the `man' program, it may be necessary to add the `-R' option of
-  `less' to the $PAGER environment variable; alternatively, you can use
-  `man's `-P' option (or adapt its configuration file accordingly).  See
-  man(1) for more details.
-
-o If the environment variable GROFF_NO_SGR is set, SGR output is disabled,
-  reverting to the old behaviour.
-
-o A new special \X'tty: sgr n' has been added; if n is non-zero or missing,
-  enable SGR output (the default).
-
-o If the new option `-i' is used (only in SGR mode), grotty sends escape
-  sequences to set the italic font attribute instead of the underline
-  attribute for italic fonts.  Note that many terminals don't have support
-  for this (including xterm).
-
-Grohtml
--------
-
-o Color support for glyphs has been added.
-
-o New option `-h' to select the style of headings in HTML output.
-
-o New option `-b' to set the background colour to white.
-
-o New options `-a' and `-g' to control the number of bits for anti-aliasing
-  used for text and graphics, respectively.  Default value is 4; 0 means
-  no anti-aliasing.
-
-o groff character/glyph entities now map onto HTML 4 character entities.
-
-Grolbp
-------
-
-o Valid paper sizes are now specified as with the new `papersize' keyword
-  in the DESC file.  Specifically, the old custom paper type format
-  `custAAAxBBB' is no longer supported.
-
-Miscellaneous
--------------
-
-o A new manual page `ditroff.7' is available.
-
-o The groff texinfo manual will now be installed, together with a bunch
-  of examples.
-
-o A new keyword `papersize' has been added to the DESC file format.  Its
-  argument is either
-
-  . a predefined paper format (e.g. `A4' or `letter')
-
-  . a file name pointing to a file which must contain a paper size
-    specification in its first line (e.g. `/etc/papersize')
-
-  . a custom paper size definition like `35c,4i'
-
-  See groff_font(5) for more details.  This keyword only affects the
-  physical dimensions of the output medium; grops, grolj4, and grolbp use it
-  currently.  troff completely ignores it.
-
-VERSION 1.17.2
-==============
-
-This is major bug-fixing release which should replace 1.17.1.
-
-Troff
------
-
-o The `IMAGE' macro in www.tmac has changed: Now the optional 2nd parameter
-  gives the horizontal image location (left, centered, or right), and the
-  optional 3rd and 4th parameter the image dimensions.
-
-VERSION 1.17.1
-==============
-
-This is mainly a bug-fixing release.
-
-Troff
------
-
-o Two new requests `de1' and `am1' which are similar to `de' and `am' but
-  with compatibility mode disabled during expansion of macros defined by
-  them.
-
-o Added request `brp'.  This is the same as `\p'.
-
-o Similar to other versions of troff, the `ns' request now works in all
-  diversions, not only in the top-level one.
-
-o New read-only number register `.ns'.  Returns 1 if in no-space mode,
-  0 otherwise.
-
-Nroff
------
-
-o Options -p (pic) and -t (tbl) added.
-
-o The environment variable GROFF_BIN_PATH is now checked before PATH for
-  finding groff.
-
-Grohtml
--------
-
-o New option `-D dir' to specify a directory in which all images are placed.
-
-o New option `-I stem' to specify an image name stame.  If not given,
-  `grohtml-XXX' is used (`XXX' is the process ID).
-
-VERSION 1.17
-============
-
-Groff
------
-
-o `-mFOO' now searches first for `FOO.tmac' and then for `tmac.FOO'.  The
-  old behaviour has been changed to overcome problems with platforms which
-  have an 8+3 file name limit, and platforms which have other versions of
-  troff installed also.  Additionally, all macro files have been renamed
-  using the latter scheme to avoid 8+3 name clashes.
-
-o The new environment variable GROFF_BIN_PATH is checked for programs groff
-  is calling (preprocessors, troff, and output devices) before PATH.  If not
-  set, it defaults to the directory where the groff binary is located.
-  Previously, it was PATH only.  The nroff script only uses GROFF_BIN_PATH
-  to find the groff binary but passes both the GROFF_BIN_PATH and PATH
-  environment variables to groff.
-
-Troff
------
-
-o The mdoc package has been completely rewritten, using the full power of
-  GNU troff to remove limitations of Unix troff (which is no longer
-  supported).  Most important changes are:
-
-  . No argument limit
-  . Almost all macros are parsed and callable (if it makes sense)
-  . `.Lb': prints library names
-  . `.Nm <punctuation>' now works as expected; `.Nm "" <punctuation>' has
-    been withdrawn
-  . Updated `.St' command
-  . `.Fx': prints FreeBSD
-  . `.Ox': prints OpenBSD
-  . `.Bsx': prints BSD/OS
-  . `.Brq', `.Bro', `.Brc': brace enclosure macros
-  . `.Bd -centered': center lines
-  . `.Bl -xwidth <string>': interpret <string> and use the resulting width
-  . Support for double-sided printing (-rD1 command line switch)
-  . Support for 11pt and 12pt document sizes (-rS11, -rS12 command line
-    switches)
-
-  `groff_mdoc.7' replaces `groff_mdoc.samples.7'; it now completely
-  documents the mdoc package.
-
-  Great care has been taken to assure backwards compatibility.  If you
-  encounter any abnormal results, please report them to bug-groff@gnu.org.
-
-o A new command line option for the `man' macros (similar to the `mdoc'
-  package) has been implemented: `-rcR=1' (now the default in nroff mode)
-  produces one single, very long page instead of multiple pages.  `-rcR=0'
-  deactivates it.
-
-o The `return' request has been added to return immediately from a macro.
-
-o A new request `nop' (no operation) has been added which is similar to
-  `if 1'.  For example,
-
-    .if t \{\
-    Hallo!
-    .\}
-
-  can now be written as
-
-    .if t \{\
-    .  nop Hallo!
-    .\}
-
-o `box' and `boxa' are two new requests which behave similarly to `di' and
-  `da' but don't include a partially filled line (which is restored after
-  ending the diversion).
-
-o The `asciify' request has been extended to `unformat' space characters
-  and some other escape sequences also.
-
-  `\ ' is no longer unformatted as a space but remains an unpaddable,
-  unbreakable space character.
-
-o The new `unformat' request is similar to `asciify' but only handles space
-  characters and tabs specially if the diversion is reread, retaining font
-  information.  This makes it possible to reformat diversions; for example
-  the following
-
-    .ll 3i
-    .
-    a01 a02 a03 a04 a05 a06 a07 a08 a09 a10.
-    .
-    .box box1
-    .ev 1
-    .nf
-    \f[B]b01 b02 b03 b04 b05 b06 b07 b08 b09 b10.\f[P]
-    .br
-    .ev
-    .box
-    .
-    c01 c02 c03 c04 c05 c06 c07 c08 c09 c10.
-    .
-    .unformat box1
-    .box1
-
-  gives
-
-    a01  a02  a03  a04 a05 a06 a07
-    a08 a09 a10.  c01 c02 c03  c04
-    c05  c06 c07 c08 c09 c10.  b01
-    b02 b03 b04 b05  b06  b07  b08
-    b09 b10.
-
-  Without the `unformat' request, space characters are converted to word
-  space nodes which are no longer stretchable, and the result would be
-
-    a01  a02  a03  a04 a05 a06 a07
-    a08 a09 a10.  c01 c02 c03  c04
-    c05  c06 c07 c08 c09 c10.  b01
-    b02 b03 b04 b05 b06 b07 b08
-    b09 b10.
-
-o The new request `linetabs' controls the `line-tabs' mode.  In line-tabs
-  mode, tab distances are computed relative to the (current) output line.
-  Otherwise they are taken relative to the input line.  For example, the
-  following
-
-    .ds x a\t\c
-    .ds y b\t\c
-    .ds z c
-    .ta 1i 3i
-    \*x
-    \*y
-    \*z
-
-  yields
-
-    a         b         c
-
-  In line-tabs mode, the same code gives
-
-    a         b                   c
-
-  The new read-only number register `.linetabs' returns 1 if in line-tabs
-  mode, and 0 otherwise.
-
-o Two new requests `tm1' and `tmc' have been added to improve writing
-  messages to the terminal.  `tm1' is similar to `tm' but allows leading
-  whitespace.  `tmc' is similar to `tm1' but doesn't emit a final newline.
-
-o For compatibility with sqtroff, the request `output' has been added.
-  The behaviour is similar to `\!' at the top-level, that is, it directly
-  inserts its argument into the intermediate output format.  The syntax
-  is similar to .tm1, allowing leading whitespace.
-
-o The new `spreadwarn' request will make troff warn if spaces in an output
-  line are widened by a given limit or more.
-
-o Use `warnscale' to change the scaling indicator troff will use for
-  warning messages.
-
-o A new request `dei' (define indirect) has been added.  The first and
-  second parameter of `dei' are taken from string registers rather than
-  directly; this very special request is needed to make `trace.tmac'
-  independent from the escape character (which might even be disabled).
-
-o It is now possible to save and restore the escape character with two new
-  requests `ecs' and `ecr'.
-
-o The new escape sequence \B'...' is an analogon to `\A': If the string
-  within the delimiters is a valid numeric expression, return character `1',
-  and `0' otherwise.
-
-o The new escape sequence `\:' inserts a zero-width break point.  This is
-  similar to `\%' but without a soft hyphen character.
-
-o The `tr' request can now map characters onto `\~'.
-
-o Calling the `fam' request without an argument switches back to the
-  previous font family.
-
-o The new read-only register `.int' is set to a positive value if the last
-  output line is interrupted (i.e., if the input line contains `\c').
-
-o The `writem' request is not new, but hasn't been documented before.  This
-  is similar to `write' but instead of a string the contents of a given
-  macro or string is written to a stream.
-
-o The read/write number register `hp' to get/set the current horizontal
-  position relative to the input line isn't new but hasn't been documented
-  properly before.
-
-o `\X' and `\Y' are now transparent for end-of-sentence recognition.
-
-o The `cu' request in nroff mode now works as documented (i.e., it
-  underlines spaces also).
-
-Grog
-----
-
-o The grog script now works in non-compatibility mode also (which is the
-  default).  As usual, use the `-C' option to activate compatibility mode.
-
-Grops
------
-
-o A new option `-P' resp. a new environment variable `GROPS_PROLOGUE' has
-  been added to select a different prologue file.
-
-o The effect of the former `-mpsnew' option to access more Type 1 characters
-  is now the default and no longer available.  To get the old behaviour
-  (i.e., emulation of some glyphs by composition) use `-mpsold'.
-
-Miscellaneous
--------------
-
-o For security reasons the following changes have been done:
-
-  . The tmac.safer file has been replaced with a built-in solution; .open,
-    .opena, .pso, .sy, and .pi are completely disabled in safer mode (which
-    is the default); to enable these requests the `-U' command line flag
-    must be used.
-
-  . Files specified with the .mso request or given with the `-m' command
-    line option, and hyphenation patterns loaded with `.hpf' are no longer
-    searched in the current directory by default (besides the usual tmac
-    path).  Instead, the home directory is used.  To add the current
-    directory, either use the `-U' or `-M' command line option or set the
-    GROFF_TMAC_PATH environment variable to an appropriate value.
-
-  . troffrc, troffrc-end, and eqnrc are neither searched in the current nor
-    in the home directory (even if -U is given).  Use -M or GROFF_TMAC_PATH
-    to change that.
-
-  . Similarly, the current directory is no longer part of the font path.
-    Use the `-F' command line option or the GROFF_FONT_PATH environment
-    variable if you really need the current directory.
-
-o groff now installs its data files into /usr/local/share/groff/<version> by
-  default, following the GNU standard.  Additionally, a local tmac directory
-  (by default /usr/local/share/groff/site-tmac) is scanned before the
-  standard tmac directory.  Wrapper files for system-specific macro packages
-  (if necessary) are put into /usr/local/lib/groff/site-tmac; this directory
-  is searched before the local tmac directory.
-
-o All programs now have option `-v' to show the version number; they exit
-  immediately afterwards, following the GNU standards.  Additionally,
-  `--version' and `--help' have been added, doing the obvious actions.
-
-VERSION 1.16.1
-==============
-
-Bug fixes only; no user-visible changes.
-
-VERSION 1.16
-============
-
-Groff
------
-
-The anachronism of calling the man macro package with `-man' has been fixed;
-now you can say `-m man' also. The same is true for `ms', `me', `markup',
-`mandoc', and `mdoc'.
-
-A new switch `-g' for calling `grn' is available.
-
-A new switch `-G' for calling `grap' is available.
-
-EBCDIC support for tty devices has been added.  On such hosts, IBM code page
-1047 is available with -Tcp1047 instead of -Tascii and -Tlatin1 (and, for
-the moment, -Tutf8).  Note that non-tty devices are not yet supported (but
-installed).
-
-Troff
------
-
-A new command line option to the `man' macros is available: `-rSxx' (with
-`xx' either 10, 11, or 12) to set the base document font size to `xx'
-points.  Additionally, `.SH' now produces larger headings than `.SS'.
-
-To solve a problem with the .PSPIC macro which needs the `-U' switch of
-troff to access an external program (psbb), a new request .psbb is now
-available to get the bounding box of a PostScript image file.  The values
-(in PostScript units) are returned in the new read-only number registers
-`llx', `lly', `urx', and `ury'.  Consequently, .PSPIC has been adapted to
-use the new request, and the psbb program has been removed.
-
-A new predefined writable number register, `year', has been added.  It
-contains the current year.
-
-A new read-only register, `.Y', has been added.  It contains the revision
-number of the groff package.
-
-`\fP' now behaves as expected in situations like the following where the
-font `foo' is undefined:
-
-  .B bold text
-  normal text \f[foo]bar\fP normal text
-
-Previously, the text after \fP appeared as bold.
-
-The `substring' request is not new, but hasn't been documented before.
-
-The predefined `.T' string register (which holds the current output device)
-is not new, but hasn't been documented before.
-
-A new request `length' computes the length of a string and returns it in
-a number register.
-
-The macro files `tmac.a4' (for specifying A4 paper format) and `tmac.trace'
-(a debugging aid) are now installed also.
-
-A new resource file, `troffrc-end', is now available.  It is invoked after
-all user-specified macros.  Currently used by the html device to include
-tmac.html; thus no need for users to specify -mhtml anymore.
-
-The soft hyphen character now has a glyph name: `shc'.
-
-The latin-1 character 173 (PS name `periodcentered') has got the troff glyph
-name `pc' and is no longer intermixed with the symbol character `md' (PS
-name `mathdot').
-
-ASCII character 34 (PS name `quotedbl') has got the troff glyph name `dq'
-(which is an alias to character `"').
-
-ASCII character 39 (PS name `quoteright') has got the troff glyph name `cq'
-(which is an alias to character "'").
-
-Some additions to the font description files have been implemented for
-better support of HTML output:
-
-  The new format of lines in the `charset' subsection of font description
-  files is
-
-     name metrics type code [entity_name] [-- comment]
-
-  Currently, only the font description files in devhtml use the optional
-  entity_name string to define glyph entities in HTML.  Everything after the
-  entity_name field is ignored; in case this field isn't used, two hyphen
-  characters are now necessary to start a comment.
-
-  Two new requests are available in DESC files (currently used only with
-  grohtml):
-
-    use_charnames_in_special
-      This command indicates that troff should encode named characters
-      inside special commands.
-
-    pass_filenames
-      requests that troff tells the driver the source file name being
-      processed.  This is achieved by another tcommand: `F filename'.
-
-Grotty
-------
-
-Bruno Haible <haible@clisp.cons.org> contributed support for UTF8 output.
-
-Grohtml
--------
-
-Added .LINE macro to tmac.arkup.
-
-The obsolete `.LINK' macro has been removed.
-
-.URL, .FTP, and .MAILTO macros now accept an optional third argument which
-will be immediately appended to the second argument (to be used with
-punctuation, for example).
-
-Grodvi
-------
-
-The font size 11pt has been changed to 10.95pt (as used in LaTeX 2e).
-
-A new font file CWI (using cmitt10; this is typewriter italic) has been
-added.
-
-Grolbp
-------
-
-A new driver for Canon CAPSL printers (LBP-4 and LBP-8 series laser
-printers).  This code has been contributed by Francisco Andres Verdu
-<pandres@dragonet.es>.
-
-Grn
----
-
-A new preprocessor to process gremlin pictures.  It is based on the
-original Berkeley implementation of grn, written by David Slattengren
-and Barry Roitblat, and has been adapted to groff by Daniel Senderowicz
-<daniel@synchrods.com> and Werner Lemberg <wl@gnu.org>.
-
-Pic
----
-
-Added the `srand' command to set the seed for a new sequence of
-pseudo-random numbers to be returned by `rand'.
-
-Gxditview
----------
-
-Simplified installation: The Imakefile will now be configured (by groff's
-configure script).
-
-Documentation
--------------
-
-Three new man pages are available: groff_tmac.5 (documenting how troff macros
-are accessed and where they are found), groff.7 (a short reference of the GNU
-roff language), and roff.7 (a general survey on GNU troff).
-
-Miscellaneous
--------------
-
-A partial port to win32 (for use with Microsoft Visual C++ 6.0) is now part
-of the distribution.  It has been contributed by Blake McBride
-<blake@florida-software.com>.
-
-More information about programs, macros, documentation, etc., which is
-related to groff has been collected in the file `MORE.STUFF'.
-
-VERSION 1.13, 1.14, 1.15
-========================
-
-Bug fixes only; no user-visible changes.
-
-VERSION 1.12
-============
-
-Finally, there are new maintainers for groff.  Mailing lists and a CVS
-repository are available also. See the file README for details.  Not all
-reported bugs could be fixed, so please send mails again if something is
-still not working.
-
-Most of the installation problems should have vanished now (most
-notably the $(tmac_wrap) bug).
-
-There is now a man page called groff_man.7 which documents the basics of the
--man macros.  It has been originally written by Susan G. Kleinmann
-<sgk@debian.org>.
-
-A (still incomplete) groff reference manual in texinfo format originally
-contributed by Trent A. Fisher <trent@gnurd.portland.or.us>.
-
-me.man and msafer.man have been renamed to groff_me.man
-resp. groff_msafer.man for consistency.
-
-Default strings for macros in doc-common resp. tmac.an no longer contain the
-word `UNIX'.
-
-groff should now be Y2k safe (fixes contributed by Paul Eggert
-<eggert@twinsun.com>).
-
-Following the GNU standards, groff will now use the prefix `/usr/local/' as
-the default instead of replacing an existent groff binary.
-
-groff, troff, nroff, and pic now support the -U flag to activate unsafe
-behaviour (without -msafer); the -S flag for using the -msafer macros is now
-the default.
-
-Grohtml
--------
-
-This is a new output device for producing HTML output contributed by Gaius
-Mulley <gaius@glam.ac.uk>.  It is still very alpha but has been included
-into the distribution so that a lot of people have a chance to test it.  Bug
-reports are highly welcome.
-
-Grolj4
-------
-
-Duplex printing support has been contributed by Jeffrey Copeland
-<jeff@opennt.com>.
-
-Soelim
-------
-
-Added -I option for defining include paths (patch contributed by Peter
-Miller <peterm@jna.com.au>).
-
-Gxditview
----------
-
-Fallback resources added (patch contributed by Larry Jones
-<larry.jones@sdrc.com>).
-
-Will now support 8 gray levels.
-
-mm
---
-
-New version 1.32 (contributed by Joergen Haegg <jh@axis.com>).
-
-VERSION 1.11
-============
-
-Complete documentation for pic is now in the file doc/pic.ms.  It was
-contributed by Eric S. Raymond, <esr@thyrsus.com>, who is emphatically
-*not* volunteering to take over groff as he is way overworked with
-half a dozen other projects.
-
-VERSION 1.10
-============
-
-The directory where data files are installed has been changed from
-/usr/local/lib/groff to /usr/local/share/groff to comply with the
-latest GNU coding standards.
-
-By default groff programs with Unix equivalents are installed with a
-"g" prefix unless there is an existing (non-groff) troff installation.
-
-A new approach is used to make system macro packages available to
-groff.  Instead of simply including /usr/lib/tmac in the list of
-directories searched by groff, the installation process creates for
-each system macro package a wrapper macro package in the groff macro
-directory that references the system macro package.  The groff macro
-packages are now installed with a leading "g" prefix if there is a
-system version of the same macro package, and otherwise without the
-"g" prefix, with the exception that the groff version of -me which is
-always installed as -me.
-
-There is a new device, lj4, for the HP LaserJet 4 (and PCL5
-compatibles).
-
-Groff
------
-
-groff has a -S option that prevents the use of unsafe features in pic
-and troff.  This uses a new -S option of pic and the -msafer macros
-for troff.
-
-Troff
------
-
-The `blm' request specifies a macro to be invoked when a blank line is
-encountered.
-
-Pic
----
-
-A -S (safer) option disables the sh command.
-
-Grops
------
-
-The -m option enables manual feed.
-
-VERSION 1.09
-============
-
-\(rn will now produce a character that has the traditional metrics,
-and will form corners with \(ul and \(br.  This means that it will not
-align properly with \(sr.  Instead there's a new character
-\[radicalex] which aligns with \(sr; this is used by eqn for doing
-square roots.
-
-Troff
------
-
-The `pso' request allows you to read from the standard output of a
-command.
-
-Grops
------
-
-The PSPIC macro has options to allow the horizontal alignment of the
-graphic to be specified.
-
-VERSION 1.08
-============
-
-Troff
------
-
-The escape sequence \V[xxx] will interpolate the value of the
-environment variable xxx.
-
-Tbl
----
-
-The decimalpoint option can be used to specify the character to be
-recognized as the decimal point character in place of the default
-period.
-
-VERSION 1.07
-============
-
-Groff
------
-
-The environment variable GROFF_COMMAND_PREFIX can be used to control
-whether groff looks for `gtroff' or `troff' (similarily for the
-preprocessors.)
-
-Troff
------
-
-Multilingual hyphenation is supported by new `hpf' and `hla' requests,
-and by a `\n[.hla]' number register.  The -H option has been removed.
-Files of hyphenation patterns can have comments.
-
-When a font cannot be found, troff gives a warning (of type `font',
-enabled by default) instead of an error.
-
-There's a new request `trnt' that's like `tr' except that it doesn't
-apply to text transparently throughput into a diversion with \!.
-
-Tbl
----
-
-There is a `nokeep' option which tells tbl not to use diversions to
-try to keep the table on one page.
-
-Eqn
----
-
-Setting the parameter `nroff' to a non-zero value causes `ndefine' to
-behave like `define' and `tdefine' to be ignored.  This is done by
-eqnrc when the current device is ascii or latin1.  There's a `neqn'
-script that just does `eqn -Tascii'.
-
-Grotty
-------
-
-grotty uses whatever page length was specified using the `pl' request
-rather than using the paperlength command in the DESC file.  The
-paperwidth command in the DESC file is also ignored.
-
-VERSION 1.06
-============
-
-The programs in groff that have Unix counterparts can now be installed
-without a leading `g' prefix.  See the `g' variable in the Makefile.
-
-The g?nroff script simulates the nroff command using groff.
-
-New special characters \(+h, \(+f, \(+p, \(Fn, \(Bq, \(bq, \(aq, \(lz,
-\(an.  See groff_char(7).
-
-^L is now a legal input character.
-
-Groff
------
-
-The Xps pseudo-device has disappeared.  Instead there is a new -X
-option that tells groff to use gxditview instead of the usual
-postprocessor. (So instead of -TXps, use -XTps or just -X if your
-default device is ps.)
-
-The postprocessor to be used for a particular device is now specified
-by a `postpro' command in the DESC file rather than being compiled
-into groff.  Similarly the command to be used for printing (with the
--l option) is now specified by a `print' command in the DESC file.
-
-The groff command no longer specifies eqnchar as an input file for
-eqn.  Instead eqn automatically loads a file `eqnrc'.  The groff
-command no longer passes the -D option to eqn.  Instead eqnrc sets the
-draw_lines parameter.
-
-The groff command no longer tells troff to load a device-specific
-macro file.  This is handled instead by the `troffrc' file, which is
-always loaded by troff.
-
-The shell script version of groff has been removed.
-
-Troff
------
-
-The `rchar' request removes a character definition established with `char'.
-
-Compatibility mode is disabled and the escape character is set to `\'
-while a character definition is being processed.
-
-The `\#' escape sequence is like `\"' except that the terminating
-newline is ignored.
-
-The `shc' request tells troff which character to insert (instead of
-the default \(hy) when a word is hyphenated at a line break.
-
-A font name of 0 (zero) in the DESC file will cause no font to be
-mounted on the corresponding font position.  This is useful for
-arranging that special fonts are mounted on positions on which users
-are not likely explicitly to mount fonts.  All groff devices now avoid
-initially mounting fonts on positions 5-9.
-
-The `do' request allows a single request or macro to be interpreted
-with compatibility mode disabled.
-
-troff automatically loads a file `troffrc' before any other input file.
-This can be prevented with the -R option.  This file is responsible
-for loading the device-specific macros.
-
-Pic
----
-
-The -x option has been removed and a -n option has been added.  By
-default, pic now assumes that the postprocessor supports groff
-extensions.  The -n option tells pic to generate output that works
-with ditroff drivers.  The -z option now applies only to TeX mode.
-
-The -p option has been removed. Instead if the -n option is not
-specified, pic generates output that uses \X'ps: ...' if the \n(0p
-register is non-zero and tmac.ps sets this register to 1.
-
-In places where you could 1st or 5th you can now say `i'th or `i+1'th
-(the quotes are required).
-
-Eqn
----
-
-Eqn now automatically reads a file `eqnrc' from the macro directory.
-This performs the same role that the eqnchar files used to.  This can
-be prevented by the -R option.
-
-Setting the draw_lines parameter to a non-zero value causes lines to
-be drawn using \D rather than \l.  The -D option is now obsolete.
-
-`uparrow', `downarrow' and `updownarrow' can be used with `left' and
-`right'.
-
-The amount of extra space added before and after lines containing
-equations can be controlled using the `body_height' and `body_depth'
-parameters.
-
-Grops
------
-
-Font description files have been regenerated from newer AFM files.
-You can get access to the additional characters present in the text
-fonts in newer PostScript printers by using -mpsnew.
-
-The default value of the -b option is specified by a `broken' command
-in the DESC file.
-
-With the -g option, grops will generate PostScript code that guesses
-the page height.  This allows documents to be printed on both letter
-(8.5x11) and A4 paper without change.
-
-Grodvi
-------
-
-ISO Latin-1 characters are available with -Tdvi.  Format groff_char(7)
-with groff -Tdvi for more information.
-
-Grotty
-------
-
-The -mtty-char macros contain additional character definitions for
-use with grotty.
-
-Macros
-------
-
-In previous releases the groff -me macros treated the $r and $R number
-registers in a way that was incompatible with the BSD -me macros.  The
-reason for this was that the approach used by the BSD -me macros does
-not work with low resolution devices such as -TX75 and -TX100.
-However, this caused problems with existing -me documents.  In this
-release, the vertical spacing is controlled by the $v and $V registers
-which have the same meaning as $r and $R in earlier groff releases.
-In addition, if the $r or $R register is set to a value that would be
-correct for for the BSD -me macros and a low resolution device is not
-being used, then an appropriate value for the $v or $V register will
-be derived from the $r or $R register.
-
-The groff -me macros work with -C and (I think) with Unix troff.
-
-For backward compatibility with BSD -me, the \*{ and \*} strings are
-also available as \*[ and \*].  Of course, \*[ will only be usable
-with -C.
-
-The \*T string has been deleted.  Use \*(Tm instead.
-
-Xditview
---------
-
-The `n', Space and Return keys are bound to the Next Page action.  The
-`p', BackSpace and Delete keys are bound to the Previous Page action.
-The `q' key is bound to the Quit action.
-
-The `r' key is bound to a rerasterize action that reruns groff, and
-redisplays the current page.
-
-VERSION 1.05
-============
-
-Pic
----
-
-There is a alternative assignment operator `:=' which interacts
-differently with blocks.
-
-There is a new command `command', which allows the values of variables
-to be passed through to troff or TeX.
-
-The `print' command now accepts multiple arguments.
-
-String comparison expressions (using `==' or `!=') are allowed in more
-contexts.
-
-Grotty
-------
-
-Horizontal and vertical lines drawn with \D'l ...' will be rendered
-using -, | and + characters.  This is intended to give reasonable
-results with boxed tables.  It won't work well with pic.
-
-Macros
-------
-
-The -mdoc macros have been upgraded to the version in the second
-Berkeley networking release.  This version is not completely
-compatible with earlier versions; the old version is still available
-as -mdoc.old.  The grog script has been enhanced so that it can
-usually determine whether a document requires the old or new versions.
-
-With -TX75, -TX100 and -TXps, the PSPIC macro will produce a box
-around where the picture would appear with -Tps.
-
-VERSION 1.04
-============
-
-An implementation of the -mm macros is included.
-
-The directory in which temporary files are created can be controlled
-by setting the GROFF_TMPDIR or TMPDIR environment variables.
-
-Pic
----
-
-Some MS-DOS support (see pic/make-dos-dist).
-
-Grops
------
-
-There are two new \X commands (\X'ps: invis' and \X'ps: endinvis')
-which make it possible to have substitute characters that are
-displayed when previewing with -TXps but ignored when printing with
-grops.
-
-Xditview
---------
-
-Support for scalable fonts.
-
-VERSION 1.03
-============
-
-No changes other than bug fixes.
-
-VERSION 1.02
-============
-
-There is an implementation of refer and associated programs.  groff -R
-preprocesses with grefer; no mechanism is provided for passing
-arguments to grefer because most grefer options have equivalent
-commands which can be included in the file.  grog also supports refer.
-
-There is an alternative perl implementation of the grog script.
-
-The code field in lines in the charset section of font description
-files is now allowed to contain an arbitrary integer (previously it
-was required to lie between 0 and 255).  Currently grops and grodvi
-use only the low order 8 bits of the value.  Grodvi will use the
-complete value; however, this is unlikely to be useful with
-traditional TeX tools (.tfm files only allow 8 bit character codes.)
-
-Left and right double quotes can be obtained with \(lq and \(rq
-respectively.
-
-There is a new program called pfbtops which translates PostScript
-fonts in pfb format to ASCII.
-
-A slightly modified version of the Berkeley tmac.doc is included.
-
-Troff
------
-
-In long escape names the closing ] is now required to be at the same
-input level as the opening [.
-
-The \A'S' escape sequence returns 1 or 0 according as S is or is not
-suitable for use as a name.
-
-\~ produces an unbreakable space that can be stretched when the line
-is adjusted.
-
-The `mso' request is like the `so' request except that it searches for
-the file in the same directories in which tmac.X is searched for when
-the -mX option is given.
-
-The escape sequence `\R' is similar to the `nr' request.

-
-A new `special' primitive allows you to add new types of unary
-constructs by writing a troff macro.
-
-Pic
----
-
-The implementation no longer uses gperf.
-
-Grops
------
-
-The compile-time -DBROKEN_SPOOLER option has been replaced by a
-BROKEN_SPOOLER_FLAGS option.  This allows more precise control over
-how grops should workaround broken spoolers and previewers.  There is
-a new -b option that can change this at run-time.
-
-Grops now generates PostScript that complies with version 3.0 of the
-Document Structuring Convention.
-
-The resource management component of grops (the part that deals with
-imported documents and downloadable fonts) has been rewritten and now
-supports version 3.0 of the Document Structuring Conventions.  The
-%%DocumentFonts comment is no longer supported; you must use the
-%%Document{Needed,Supplied}{Fonts,Resources} comments instead
-(or as well.)
-
-tmac.psatk contains some macros that support the mechanism used by the
-Andrew Toolkit for including PostScript graphics in troff documents.
-
-Xditview
---------
-
-Parts of xditview have been rewritten so that it can be used with the
-output of gtroff -Tps.  groff -TXps will run gtroff -Tps with
-gxditview.
-
-There is a new menu entry `Print' which brings up a dialog box for
-specifying a command with which the file being previewed should be
-printed.
-
-Xditview now uses imake.
-
-VERSION 1.01
-============
-
-The groff command now understands the gtroff `-a' and `-i' options.
-
-With the `m' and `n' scale indicators, the scale factor is rounded
-horizontally before being applied.  This makes (almost) no difference
-for devices with `hor' equal to 1, but it makes groff with -Tascii or
--Tlatin1 behave more like nroff in its treatment of these scale
-indicators.  Accordingly tmac.tty now calls the `nroff' request so
-that the `n' condition will be true.
-
-The device-specific macros (tmac.ps, tmac.dvi, tmac.tty and tmac.X)
-have been made to work at least somewhat with -C.  In particular the
-special characters defined by these macros now work with -C.
-
-groff -Tdvi -p will now pass pic the -x flag; this will enable filling
-of arrowheads and boxes, provided that your dvi driver supports the
-latest version of the tpic specials.
-
-Eqn
----
-
-There is a new `-N' option that tells eqn not to allow newlines in
-delimiters.  This allows eqn to recover better from missing closing
-delimiters.  The groff command will pass on a `-N' option to eqn.
-
-Grops
------
-
-You can now use psfig with grops.  See the file ps/psfig.diff.  I do
-not recommend using psfig for new documents.
-
-The command \X'ps: file F' is similar to \X'ps: exec ...' except that
-the PostScript code is read from the file F instead of being contained
-within the \X command.  This was added to support psfig.
-
-Grodvi
-------
-
-There are font files HB and HI corresponding to cmsssbx10 and cmssi10.
-
-Macros
-------
-
-The groff -me macros now work with the -C option.  As a result, they
-may also work with Unix nroff/troff.
-
-In -me, the $r and $R number registers now contain the line spacing as
-a percentage of the pointsize expressed in units (normally about 120).
-The previous definition was useless with low resolution devices such
-as X75 and X100.
-
-VERSION 1.00
-============
-
-A -ms-like macro-package is now included.
-
-The name for the Icelandic lowercase eth character has been changed
-from \(-d to \(Sd.
-
-Troff
------
-
-There is a new request `nroff', which makes the `n' built-in condition
-true and the `t' built-in condition false; also a new request `troff'
-which undoes the effect of the `nroff' request.  This is intended only
-for backward compatibility: it is usually better to test \n(.H or
-\n(.V or to use the `c' built-in condition.
-
-The \R escape sequence has been deleted.  Use \E instead.
-
-There are `break' and `continue' requests for use with the `while'
-request.
-
-There is a request `hym' that can ensure that when the current
-adjustment mode is not `b' a line will not be hyphenated if it is no
-more than a given amount short, and a request `hys' that can ensure
-that when the current adjustment mode is `b' a line will not be
-hyphenated if it can be justified by adding no more than a given
-amount of extra space to each word space.
-
-There is a request `rj' similar to `ce' that right justifies lines.
-
-A warning of type `space' will be given when a call is made to an
-undefined request or macro with a name longer than two characters, and
-the first two characters of the name make a name that is defined.
-This is intended to find places where a space has been omitted been a
-request or macro and its argument.  This type of warning is enabled by
-default.
-
-Pic
----
-
-A comma is permitted between the arguments to the `reset' command.
-
-For use with TeX, there is a new `-c' option that makes gpic treat
-lines beginning with `.' in a way that is more compatible with tpic
-(but ugly).
-
-Eqn
----
-
-It is no longer necessary to add `space 0' at the beginning of
-complicated equations inside pictures.
-
-`prime' is now treated as an ordinary character, as in Unix eqn.  The
-previous behaviour of `prime' as an operator can now be obtained using
-`opprime'.
-
-Xditview
---------
-
-There are two new devices X75-12 and X100-12 which are the same as X75
-and X100 except that they are optimized for documents that use mostly
-12 point text.
-
-VERSION 0.6
-===========
-
-The installation process has been refined to make it easy for you to
-share groff with someone who has the same type of machine as you but
-does not have a C++ compiler.  See the end of the INSTALL file for
-details.
-
-There is a man page for the tfmtodit program which explains how to use
-your own fonts with groff -Tdvi.
-
-There is a man page for afmtodit which explains how to use your own
-PostScript fonts with groff -Tps.
-
-The \N escape sequence is now fully supported.  It can now be used to
-access any character in a font by its output code, even if it doesn't
-have a groff name.  This is made possible by a convention in the font
-files that a character name of `---' refers to an unnamed character.
-The drivers now all support the `N' command required for this.  The font
-description files have been updated to include unnamed characters.
-
-The `x' command in font description files has been removed: instead
-any unknown commands are automatically made available to the drivers.
-If you constructed your own font files with an earlier version of
-tfmtodit or afmtodit, you must construct them again using the current
-version.
-
-Characters between 0200 and 0237 octal are no longer legal input
-characters.  Note that these are not used in ISO 8859.
-
-A command called `grog' has been added, similar to the `doctype'
-command described in Kernighan and Pike.
-
-Groff
------
-
-The groff command has some new options: -V prints the pipeline
-instead of executing it; -P passes an argument to the postprocessor,
--L passes an argument to the spooler.
-
-There is a C++ implementation of the groff command.  This handles some
-things slightly better than the shell script.  In particular, it can
-correctly handle arguments containing characters that have a special
-meaning to the shell; it can give an error message when child
-processes other than the last in the pipeline terminate abnormally;
-its exit status can take account of the exit statuses of all its child
-processes; it is a little more efficient; when geqn is used, it
-searches for the eqnchar file in the same way that font metric files
-are searched for, rather than expecting to find it in one particular
-directory.
-
-Gtroff
-------
-
-There is font translation feature: For example, you can tell gtroff to
-use font `HR' whenever font `H' is requested with the line
-  .ftr H HR
-This would be useful for a document that uses `H' to refer to
-Helvetica.
-
-There are some new number registers: `.kern' contains the current kern
-mode, `.lg' the current ligature mode, `.x' the major version number,
-`.y' the minor version number, `.ce' the number of lines to be
-centered in the current environment, `.trunc' the amount of vertical
-space truncated by the most recently sprung vertical position trap,
-`.ne' the amount of vertical space needed in the last `ne' request
-that caused a vertical position trap to be sprung.
-
-The `cf' request now behaves sensibly in a diversion.  If used in a
-diversion, it will now arrange for the file to be copied to the output
-when the diversion is reread.
-
-There is a new request `trf' (transparent file) similar to `cf', but
-more like `\!'.
-
-There is a new escape sequence `\Y[xxx]', roughly equivalent to
-`\X'\*[xxx]'', except that the contents of string or macro xxx are not
-interpreted, and xxx may contain newlines.  This requires an output
-format extension; the drivers have been modified to understand this.
-Grops has also been modified to cope with newlines in the arguments to
-\X commands; grops has a new \X command mdef, which is like def except
-that it has a first argument giving the number of definitions.
-
-There is a new warning category `escape' which warns about unknown
-escape sequences.
-
-The `fp' request now takes an optional third argument giving the external
-name of the font.
-
-The `\_' character is now automatically translated to `\(ul' as in troff.
-
-The environment variable `GROFF_HYPHEN' gives the name of the file
-containing the hyphenation patterns.
-
-There is a `\C'xxx'' escape sequence equivalent to `\[xxx]'.
-
-Characters ", ', ), ], *, \(dg are now initially transparent for the purposes
-of end of sentence recognition.
-
-There is an anti-recursion feature in the `char' request, so you can
-say `.char \(bu \s+2\(bu\s-2'.
-
-The limit on the number of font positions has been removed.
-Accordingly `\n[.fp]' never returns 0.
-
-The restriction on the number of numbered environments has been removed.
-
-There is a new escape sequence `\E' that makes it possible to
-guarantee that an escape sequence won't get interpreted in copy-mode.
-The `\R' escape sequence is accordingly now deprecated.
-
-Gpic
-----
-
-Arguments of the form `X anything X' (in the `copy thru', `sh', `for',
-`if' and `define' constructs) can now be of the form `{ anything }'.
-
-If the `linethick' variable is negative (as it now is initially),
-lines will be drawn with a thickness proportional to the current point
-size.
-
-The `rand' function now takes no arguments and returns a number between
-0 and 1.  The old syntax is still supported.
-
-`^' can be used in expressions to indicate exponentiation.
-
-In the `for' construct the argument to the by clause can be prefixed
-by `*' to indicate that the increment is multiplicative.
-
-A bare expression may be used as an attribute.  If the current
-direction is `dir', then an attribute `expr' is equivalent to
-`dir expr'
-
-There is a `sprintf' construct that allows numbers to be formatted and used
-wherever a quoted string can be used.
-
-The height of a text object without an explicit height attribute is
-the number of text strings associated with the object times the value
-of the `textht' variable.
-
-The maximum height and width of a picture is controlled by the
-`maxpswid' and `maxpsht' variables.
-
-Gtbl
-----
-
-Gtbl can now handle gracefully the situation where the `ce' request
-has been applied to a table.
-
-Geqn
-----
-
-The `ifdef' primitive has been generalized.
-
-A tilde accent can be put underneath a box using `utilde'.  This
-defined using a general `uaccent' primitive.
-
-Grops
------
-
-There is a new PostScript font downloading scheme which handles font
-downloading for imported illustrations.  Previously, the name of the
-file containing the font was given in the `x download' line in the
-groff font metric file.  Now, there is a `download' file which says
-for each PostScript font name which file contains that font.  Grops
-can also now handle inter-font dependencies, where one downloadable
-font depends on some other (possibly downloadable) font.
-
-The `T' font has been removed.  The characters it used to provide are
-now provided by `char' definitions in tmac.ps. TSymbol.ps has also
-been removed, and the tweaks it provided are now provided by `char'
-definitions.

-Generic Problems
-================
-
-
-
-* Displaying a man page on a terminal with/without my favourite pager
-  only gives garbage.
-
-groff by default now uses SGR escape sequences (`ANSI color') to
-control the display attributes (bold, underlined, colour) on TTYs. 
-Some terminals (e.g. `kterm') don't understand SGR, and some pagers
-(e.g. older versions of `less' or `less' without the -R option) don't
-understand SGR either.  There are three solutions to fix this, in order
-of preference; please read the grotty man page for more details.
-
-The fourth and probably best option is to update your terminal program
-and pager to versions which can handle SGR.
-
-  1. Set the GROFF_NO_SGR environment variable.
-
-  2. Pass option -c to grotty.
-
-  3. Append the following fragment to the `troffrc' file:
-
-
---- start ---
-.if n \{\
-.  nr _C \n(.C
-.  cp 0
-.
-.  \" The following code sets a top-of-page trap to disable grotty's TTY
-.  \" mode.  Since neither \X nor .output can be used before the first
-.  \" page has started, we must use a trap.  To make it work with troff's
-.  \" -o option, we wait until the first printed page.
-.
-.  de sgr@dummy
-.  .
-.
-.  rn wh wh@old
-.
-.  \" The stand-alone version.  If no other trap is set, we can safely
-.  \" insert the truncated vertical space caused by the trap (if any).
-.  \" Otherwise we assume that the document's main macro package takes
-.  \" care of that.  As soon as the trap has been executed, it is removed.
-.  de1 no@sgr
-.    if \\n[.P] \{\
-.      if (\\n[.t] == \\n[.p]) \{\
-.        rn wh@old wh
-.        rm no@sgr
-.        wh 0
-.        sp \\n[.trunc]
-.        nop \X'tty: sgr 0'
-.        sp -1
-.    \}\}
-.  .
-.
-.  wh@old 0 no@sgr

-.  cp \n[_C]
-.\}
---- end ---

-----------------------------------------------------------------------
-
-* The UTF-8 output of grotty has strange characters for the minus, the
-  hyphen, and the right quote.  Why?
-
-The used Unicode characters (U+2212 for the minus sign and U+2010 for
-the hyphen) are the correct ones, but many programs can't search them
-properly.  The same is true for the right quote (U+201D).  To map those
-characters back to the ASCII characters, insert the following code
-snippet into the `troffrc' configuration file:
-
-.if '\*[.T]'utf8' \{\
-.  char \- \N'45'
-.  char  - \N'45'
-.  char  ' \N'39'
-.\}
-
-
-----------------------------------------------------------------------
-
-* My document says that the current year is 19100, not 2000.
-
-In groff, as in traditional troff, the yr number register yields the
-year minus 1900.  Unfortunately, there is a longstanding bug in the
-Troff User's Manual <http://cm.bell-labs.com/cm/cs/cstr/54.ps.gz>,
-which incorrectly claims that yr is the last two digits of the year.
-This claim was never true of either Unix troff or of groff.
-
-If your text looks like this:
-
-	.\" Wrong:
-	This document was formatted in 19\n(yr.
-
-you can correct it as follows:
-
-	This document was formatted in \n[year].
-
-or, if you want to be portable to older troff versions, as follows:
-
-	.nr y4 1900+\n(yr
-	This document was formatted in \n(y4.
-
-----------------------------------------------------------------------
-
-* groff can't handle my troff document.  It works fine with AT&T
-  troff.
-
-Read the section on incompatibilities in groff_diff(7).  Try using
-the -C option.  Alternatively there's the sed script
-`tmac/fixmacros.sed' which will attempt to edit a file of macros so
-that it can be used with groff without the -C flag.
-
-----------------------------------------------------------------------
-
-* gtroff doesn't understand lines like `.ce99' with no space between
-  the name of the request or macro and the arguments.
-
-gtroff requires a space between macro or request and its arguments
-because it allows the use of long names for macros and requests.  You
-can use the -C option or the `cp' request to put gtroff into a
-compatibility mode in which it is not possible to use long names for
-macros but in which no space is required between macros and their
-arguments.  The use of compatibility mode is strongly discouraged.
-
-----------------------------------------------------------------------
-
-* groff -Tdvi produces dvi files that use fonts at weird
-  magnifications.
-
-Yes, it does.  You may need to compile fonts with Metafont at these
-magnifications.  The CompileFonts script in the devdvi/generate
-directory may help you to do this.  (It will take a *long* time on
-slow computers.)
-
-----------------------------------------------------------------------
-
-* Groff doesn't use the font names I'm used to.
-
-Use the `ftr' request.  See groff_diff(7).
-
-----------------------------------------------------------------------
-
-* pic output is not centered horizontally; pictures sometimes run off
-  the bottom of the page.
-
-The macro package you are using is not supplying appropriate
-definitions of PS and PE.  Give groff a -mpic option.
-
-----------------------------------------------------------------------
-
-* gpic doesn't accept the syntax `chop N M' for chopping both ends of
-  a line.
-
-The correct syntax is `chop N chop M'.
-
-----------------------------------------------------------------------
-
-* With gpic -t, when I print `line ->; box' using a dvi to ps program,
-  the arrow head sticks through into the inside of the box.
-
-The dvi to ps program should be modified to set the line cap and line
-join parameters to 1 while printing tpic specials.
-
-----------------------------------------------------------------------
-
-* gtroff gives warnings about lines like
-  .ev	\" a comment
-  (with a tab after the .ev).
-
-A tab character cannot be used as a substitute for a space character
-(except in one case: between a control character at the beginning of a
-line and the name of a macro or request).  For example, in Unix troff
-
-  .ps	\" restore the previous point size
-
-(with a tab after the .ps) will NOT restore the previous point-size;
-instead it will be silently ignored.  Since this is very likely to be
-an error, gtroff can give a warning about it.  If you want to align
-comments, you can do it like this:
-
-  .ev\"				\" a comment
-
-----------------------------------------------------------------------
-
-* I don't like the page headers and footers produced by groff -man.
-
-There seem to be many different styles of page header and footer
-produced by different versions of the -man macros.  You will need to
-put modified macros from tmac/an-old.tmac into man.local.  More
-information is available in groff_man(7).
-
-----------------------------------------------------------------------
-
-* Where can I get grap?
-
-Ted Faber <faber@lunabase.org> has written a freely available grap:
-
-  http://www.lunabase.org/~faber/Vault/software/grap/
-
-----------------------------------------------------------------------
-
-* The \n(st and \n(sb registers don't seem to work.  I thought \w set
-  them to the height and depth of its argument, but the registers
-  always seem to be 0.
-
-\n(st and \n(sb aren't supposed to give the height and depth of the
-string rather they give the minimum and maximum vertical displacement
-of the baseline.  For example for \v'2u'\v'-3u', \n(st will be 1 and
-\n(sb will be -2.  The height and depth of the string is available in
-the \n[rst] and \n[rsb] registers: these are groff extensions.
-
-----------------------------------------------------------------------
-
-* While formatting a manual page, groff complains about not being able
-  to break lines.  The problem seems to be caused by a line like:
-  .TP \w'label'+2
-
-The -man documentation says that the default scale indicator for TP
-macro is `n'.  The groff -man macros implement this correctly, so that
-the argument will be evaluated as if it were
-
-  \w'label'n+2n
-
-The Unix -man macros don't implement this correctly (probably because
-it's hard to do in Unix troff); they just append `n' to the entire
-argument, so that it will be evaluated as if it were
-
-  \w'label'u+2n
-
-The solution is to fix the manual page:
-
-  .TP \w'label'u+2
-
-----------------------------------------------------------------------
-
-* I'm having problems formatting man pages produced by the perl
-  wrapman script.
-
-Some versions of wrapman have a superfluous blank line before the .TH
-line.  This must be deleted.  Then either use groff -C, or apply the
-following patch:

-Printing and Display Problems
-=============================
-
-
-
-* I'm having problems including PostScript illustrations (EPS) using
-  the PSPIC macro and/or \X'ps: import ...'.
-
-A PostScript document must meet three requirements in order to be
-included with the PSPIC macro: it must comply with the Adobe Document
-Structuring Conventions; it must contain a BoundingBox line; it must
-be `well-behaved'.  The BoundingBox line should be of the form:
-
-  %%BoundingBox: llx lly urx ury
-
-where llx, lly, urx, ury are the coordinates of the lower left x,
-lower left y, upper right x, upper right y of the bounding box of
-marks on the page expressed as integers in the default PostScript
-coordinate system (72 units per inch, origin at bottom left corner).
-
-The most convenient program to get the bounding box of a document is
-the `ps2epsi' script coming with GhostScript.
-
-If you can't use this program, another useful tactic is to print out
-the illustration by itself (you may need to add a `showpage' at the
-end), and physically measure the bounding box.  For more detail on
-these requirements, read the specification of Encapsulated PostScript
-format.  (This is available from the Adobe file server; send a message
-with a body of `help' to ps-file-server@adobe.com.)
-
-If an EPS file to be included via \X'ps: import' does not start with
-`%!PS-Adobe-...', gtroff will still include the file, but grops will
-not add any fonts to the generated output file that are listed in the
-EPS file, even though the files are listed in the `download' file and
-are available in the devps directory.
-
-----------------------------------------------------------------------
-
-* I've configured groff for A4 paper, but gtroff still seems to think
-  that the length of a page (as returned by `\n(.p') is 11 inches.
-
-This is intentional.  The PAGE option during configuration is used
-only by grops.  For compatibility with ditroff, the default page
-length in gtroff is always 11 inches.  The page length can be changed
-with the `pl' request.
-
-A convenient way to set paper dimensions is to use the -dpaper option
-of groff, together with proper -P options for the postprocessor
-(overriding the default).  For example, use the following for PS
-output on A4 paper in landscape orientation:
-
-  groff -Tps -dpaper=a4l -P-pa4 -P-l -ms foo.ms > foo.ps
-
-See groff_tmac(5) for more information.
-
-----------------------------------------------------------------------
-
-* When I print the output of groff -Tps, the output is always shifted
-  up by about 0.7 inches; I'm using 8.5x11 inch paper.
-
-Make sure that the paper size is `letter'.  See groff_tmac(5).
-
-----------------------------------------------------------------------
-
-* When I try to run gxditview, I get the error:
-  Error: Widget viewport has zero width and/or height
-
-This error means you haven't correctly installed the application
-defaults file, GXditview.ad; `make install' does this for you
-automatically, so either you didn't do `make install', or you haven't
-passed a good `--appresdir=<DIR>' argument to groff's configure script.
-
-See the X(7) man page for information how and where application resource
-files have to be located.  Look for the XAPPLRESDIR and XUSERFILESEARCHPATH
-environment variables.
-
-----------------------------------------------------------------------
-
-* When I preview documents using -TX75 or -TX100, the layout is not
-  the same as when I print the document with -Tps: the line and page
-  breaks come in different places.
-
-Use `groff -X -Tps'.
-
-----------------------------------------------------------------------
-
-* When I try to print the output of groff -Tps, I get no output at all
-  from the printer, and the log file shows the error
-  %%[ error: undefined; offendingcommand: BP ]%%
-  I'm using TranScript spooling software.
-
-This is a bug in the page reversal filter in early versions of
-TranScript.  Change the `broken' parameter in
-/usr/local/lib/groff/font/devps/DESC to 7.
-
-----------------------------------------------------------------------
-
-* When I preview groff -Tps output using the Sun OpenWindows 2.0
-  pageview program, all the pages are displayed on top of each other.
-
-This is a defect in pageview.  Change the `broken' parameter in
-/usr/local/lib/groff/font/devps/DESC to 2.
-
-----------------------------------------------------------------------
-
-* With groff -TX75, -TX100 or -X, I can only view the first page.
-
-The left mouse button brings up a menu that allows you to view other
-pages.
-
-----------------------------------------------------------------------
-
-* When I print the output of groff -Tdvi, I just get a black dot in
-  upper left corner.
-
-Some dvi drivers (notably early versions of xtex) do not correctly
-handle dvi files that use a resolution different from that used by dvi
-files produced by TeX.  Try getting a more up to date driver.
-
-----------------------------------------------------------------------
-
-* How can I use groff with an old LaserJet printer that doesn't work
-  with groff -Tlj4?
-
-You have at least 3 options:
-
-- use groff -Tps with GNU Ghostscript;
-
-- use groff -Tdvi with a TeX .dvi to Laserjet driver;
-
-- use groff with the LaserJet driver in Chris Lewis' psroff package
-  (available for ftp from:
-  ftp.uunet.ca:/distrib/chris_lewis/psroff3.0pl17).
-
-----------------------------------------------------------------------
-
-* Groff seems to generate level 3 Postscript, but my printer is only a
-  level 1 or 2 PostScript printer.
-
-In fact groff generates only level 2 PostScript (or rather level 1
-with some extensions; see grops(1) for more information how to disable
-them).  The `%!PS-Adobe-3.0' comment at the beginning of PostScript
-output generated by groff indicates that the file conforms to
-version 3.0 of the Adobe Document Structuring Conventions.  The output
-generated by groff should be printable on any PostScript printer.
-Problems with groff output's not printing are most often caused by the
-spooling system.
-
-
-
-Platform-Dependent Macro Problems
-=================================
-
-
-
-* I get lots of errors when I use groff with the AT&T -mm macros.
-
-Use the groff -mm macros.
-
-----------------------------------------------------------------------
-
-* groff produces wrapper macros for `ms' and friends which call the
-  system's original macros.  Then, to get groff's ms macro package I
-  have to use `-mgs' instead `-ms'.  Can I avoid this?
-
-Yes.  Configure and compile groff as usual, but install it with
-
-  make install tmac_wrap=""
-
-Then no wrapper files are produced, and `-ms' will use groff's `ms'
-macros.
-
-----------------------------------------------------------------------
-
-* I'm having problems formatting HP-UX 9.0 man pages with groff -man.
-
-Copy HP's tmac.an into /usr/local/share/groff/site-tmac/an.tmac, and
-either put `.cp 1' at the beginning or filter it (and any files it
-.so's) through tmac/fixmacros.sed.
-
-----------------------------------------------------------------------
-
-* I get errors using the Unix -ms macros with groff -e -C.
-
-Apply this change:

-
-* I'm having problems formatting Ultrix man pages with groff -man.
-
-The Ultrix man pages use a number of non-standard extensions to the
-Unix man macros.  One solution is to use the Ultrix -man macros with
-groff.  Copy /usr/lib/tmac/tmac.an to
-/usr/local/share/groff/site-tmac/an.tmac and apply the following patch

-----------------------------------------------------------------------
-
-* On an SGI system, how can I make the man command use groff?
-
-From David Hinds <dhinds@allegro.stanford.edu> (some of these steps
-are unnecessary if you install with the `g' Makefile variable defined
-as empty):
-
-Create a script called 'eqn':
-
- > #! /bin/sh
- > if [ ${1:-""} = /usr/pub/eqnchar ] ; then shift ; fi
- > geqn $*
-
-and a script called 'neqn':
-
- > #! /bin/sh
- > if [ ${1:-""} = /usr/pub/eqnchar ] ; then shift ; fi
- > geqn -Tascii $*
-
-and do:
-
- > ln -s gnroff nroff
-
-and edit the end of the gnroff script to be:
-
- > rest=`echo ${1+"$@"} | sed -e 's+/usr/lib/tmac+/usr/local/lib/groff/tmac+'`
- > exec groff -Wall -mtty-char $T $opts $rest
-
-To get PostScript output from 'man -t', you also need to create a
-'psroff' script similar to 'nroff'.  Here are the context diffs:

-Compilation Problems
-====================
-
-
-
-* Compilation dies with
-
-    y.tab.c: In function `int yyparse()':
-    y.tab.c: `size_t' undeclared in namespace `std'
-
-* bison reports conflicts (either on stderr or in the `pic.output'
-  file) while processing `pic.y', and the produced pic binary doesn't
-  work at all.
-
-You need bison version 1.875b or greater.  Alternatively, use yacc or
-byacc.
-
-----------------------------------------------------------------------
-
-* There are many empty `Makefile.dep' files.  Is this a bug?
-
-No.  Real dependency files are created with a `make depend' call.
-
-----------------------------------------------------------------------
-
-* On HP-UX, the compiler complains about missing symbol `alloca'.
-
-Say
-
-  export LDFLAGS=-lPW
-
-before starting the configure script.
-
-----------------------------------------------------------------------
-
-* The configure script fails on OS/390 (z/OS) Unix.
-
-[This has been fixed in z/OS V1R3 (aka OS/390 R13).]
-
-There is a bug in the Language Environment (LE) whereby the test
-program for static destructors fails.  You will see the message
-`configure: error: a working C++ compiler is required'
-
-Applying PTF UQ42006 is supposed to fix this, but the test program is
-still returning the wrong value (1).  To work around this problem, you
-can comment out the following in the configure script (near line 2029).
-This will effectively bypass the test (static constructors and
-destructors do actually work properly):
-
-#if { (eval echo "$as_me:2029: \"$ac_link\"") >&5
-#  (eval $ac_link) 2>&5
-#  ac_status=$?
-#  echo "$as_me:2032: \$? = $ac_status" >&5
-#  (exit $ac_status); } && { ac_try='./conftest$ac_exeext'
-#  { (eval echo "$as_me:2034: \"$ac_try\"") >&5
-#  (eval $ac_try) 2>&5
-#  ac_status=$?
-#  echo "$as_me:2037: \$? = $ac_status" >&5
-#  (exit $ac_status); }; }; then
-#  echo "$as_me:2039: result: yes" >&5
-#echo "${ECHO_T}yes" >&6
-#else
-#  echo "$as_me: program exited with status $ac_status" >&5
-#echo "$as_me: failed program was:" >&5
-#cat conftest.$ac_ext >&5
-#echo "$as_me:2045: result: no" >&5
-#echo "${ECHO_T}no" >&6;{ { echo "$as_me:2046: error: a working C++ compiler is required" >&5
-#echo "$as_me: error: a working C++ compiler is required" >&2;}
-#   { (exit 1); exit 1; }; }
-#fi
-
-----------------------------------------------------------------------
-
-* I get errors when I try to compile groff with DEC C++.
-
-Fix the declaration of write() in <unistd.h> so that the second
-argument is a const char *.  Fix the declaration of open() in
-<sys/file.h> so that the first argument is a const char *.
-
-----------------------------------------------------------------------
-
-* On a host using Unix make (e.g. Solaris), if you are compiling for
-  multiple architectures by building in a subdirectory, the make stops
-  with a message like this:
-
-    make: Fatal error: Don't know how to make target `assert.o'
-
-  or like this:
-
-    make: Fatal error: Can't find /u/src/groff/src/include/Makefile.sub': No such file or directory
-
-This occurs because GNU make and Unix make handle VPATH differently,
-and the groff build relies on GNU make's VPATH handling.
-
-Use GNU make <http://www.gnu.org/software/make/> to work around this.
-In Solaris 8 and 9, GNU make is on the Software Companion CD in
-package SFWgmake and is installed as /opt/sfw/bin/gmake.  Prebuilt
-versions of GNU make for Solaris are also available from
-sunfreeware.com.
-
-----------------------------------------------------------------------
-
-* On Ultrix, the make program stops with the message
-
-    *** Error code 1
-
-    Stop.
-
-  for no apparent reason.
-
-Use GNU make.
-
-----------------------------------------------------------------------
-
-* I'm having problems compiling groff on 386BSD 0.1.
-
-If you're using ash as /bin/sh, you'll need the following patch.

-* While compiling on Xenix, ranlib libgroff.a fails.
-
-The system ranlib can't handle externals longer than 40 characters.
-Use the ranlib included in demon.co.uk:/pub/xenix/g++-1.40.3a.v1
-instead.
-
-----------------------------------------------------------------------
-
-* I get errors when I try to compile groff with Sun C++ version 3 or
-  earlier.
-
-Groff requires header files that are moderately compatible with AT&T
-C++ and ANSI C.  With some versions of Sun C++, the supplied header
-files need some of the following changes to meet this requirement:
-<string.h> must declare the mem* functions, (just add `#include
-<memory.h>' to <string.h>); the first argument to fopen and freopen
-should be declared as `const char *'; the first argument to fread
-should be declared as `void *'; the first argument to fwrite should be
-declared as `const void *'; malloc should be declared to return
-`void *'; in <alloca.h>, the declaration `extern "C" { void
-*__builtin_alloca(int); }' should be added; in <sys/signal.h> the
-return type and the second argument type of signal() should be changed
-to be `void (*)(int)'.
-
-You can either change them in place, or copy them to some other
-directory and include that directory with a -I option.
-
-----------------------------------------------------------------------
-
-* I get errors when I try to compile groff with Forte Development 6
-  or 6u1, or Sun C++ version 5.0 through 5.2.
-
-This is a known problem; see Sun bug #4301919.  See Sun patches
-109482, 109490, 109508, and 109509 for fixes.
-
-----------------------------------------------------------------------
-
-* I get warnings from the Sun linker while using gcc 3.4.0:
-
-  ld: warning: relocation error: R_SPARC_UA32:
-      file groff/src/libs/libgroff/libgroff.a(getopt.o): symbol optarg:
-      external symbolic relocation against non-allocatable
-      section .debug_info; cannot be processed at runtime:
-      relocation ignored
-
-This seems to be a known problem (Sun bugs #4910101 and #4910810,
-filed in September 2003; gcc bug #15599, filed May 2004) without a
-public fix as of this writing.  A work-around is to use option
-`-gstabs+' instead of `-g' (and a high probability that the output is
-only debuggable with gdb but not with Sun's debuggers).
-
-----------------------------------------------------------------------
-
-* I get lots of `numeric overflow' error messages whenever I run
-  groff; I compiled groff with AT&T C++ 2.0 with an ANSI C compiler.
-
-Make sure -DCFRONT_ANSI_BUG is included in DEFINES in the top-level
-Makefile.  If that doesn't solve the problem, define INT_MIN as
--INT_MAX in libgroff/lib.h.
-
-----------------------------------------------------------------------
-
-* When compiling on MacOS X, groff compiles but does not run well,
-  especially `eqn', causing many `can't break line' messages.
-
-Use  ./configure CXX=g++2  then make as usual.

-  tar xzvf groff-<version>.tar.gz
-  cd groff-<version>
-  gunzip -c ../groff-<version>-current.diff.gz | patch -p1
-
-Depending on your requirements, you may need at least some of the
-following tools to build `groff' directly from its source:
-
-  ghostscript
-  the psutils package
-  the netpbm package
-  texinfo 4.8
-  bison >= 1.875b or byacc
-
-Note that `texinfo' and `bison' or `byacc' are required only for
-building from `CVS' sources (either a checked out working copy, or a
-daily snapshot).  They are not required for building from a stable
-release tarball.  Also note that the version numbers stated are the
-minimum supported.  No version of `texinfo' < 4.8 will work, and the
-original release of `bison' 1.875 is known not to work; you *may* find
-that `bison' releases < 1.875 will work, but in case of difficulty,
-please update to a later version *before* posting a bug report.
-
-For *all* sources, you need ghostscript for creation of either `PDF' or
-`HTML' output; the `netpbm' and `psutils' packages are required only for
-`HTML' output.  If you don't intend to produce output in either of these
-formats, then these packages are unnecessary.
-
-In Linux Debian, the installation of `texinfo' is dangerous.  For it
-creates a file `install-info' that will block the system installation.
-So the created `/usr/local/bin/install-info' must be renamed.
-
-The `groff' configure script searches for the X11 headers and
-libraries `Xaw' and `Xmu'.  So the corresponding developer packages of
-your system must be installed, otherwise `groff' does not install
-`gxditview' and the `-TX*' devices.  In Debian, the developer packages
-are `libxaw7-dev' and `libxmu-dev'.
-
-Please report bugs using the form in the file `BUG-REPORT'; the idea of
-this is to make sure that FSF has all the information it needs to fix
-the bug.  At the very least, read the `BUG-REPORT' form and make sure
-that you supply all the information that it asks for.  Even if you are
-not sure that something is a bug, report it using `BUG-REPORT': this will
-enable us to determine whether it really is a bug or not.
-
-Three mailing lists are available:
-
-  bug-groff@gnu.org          for reporting bugs

-  INTRODUCTION
-  ------------
-
-  This file provides recommendations for building a Win32 implementation of
-  GNU Groff, using the MinGW port of GCC for Microsoft (TM) Windows-32
-  platforms.  It is intended to supplement the standard installation
-  instructions (see file INSTALL); it does not replace them.
-
-  You require both the MinGW implementation of GCC and its supporting MSYS
-  toolkit, which provides a Win-32 implementation of the GNU bash shell, and a
-  few other essential utilities; these may be obtained from
-
-    http://sourceforge.net/projects/mingw
-
-  by following the appropriate download links, where they are available as
-  self-extracting executable installation packages.  If installing both from
-  scratch, it is recommended that MinGW is installed first, as the MSYS
-  installer can then automatically set up the proper environment for running
-  MinGW.
-
-  Additionally, if you wish to compile groff with support for its HTML output
-  capability, some additional tools are required as decribed in the section
-  PREREQUISITES FOR HTML OUTPUT later in this file.
-
-
-  BUILDING GROFF WITH MINGW
-  -------------------------
-
-  Assuming that you have obtained the appropriate groff distribution, and that
-  you are already running an MSYS shell, then the configuration, compilation,
-  and installation of groff, using MinGW, is performed in much the same way as
-  it is described in the INSTALL file, which is provided with the groff
-  distribution.  The installation steps are summarised below:
-
-  1. Change working directory to any suitable location where you may unpack
-     the groff distribution; you must be authorized for write access.
-     Approximately 30MB of free disk space are needed.
-
-  2. Unpack the groff distribution:
-
-       tar xzf <download-path>/groff-<version>.tar.gz
-
-     This creates a new sub-directory, groff-<version>, containing an image of
-     the groff source tree.  You should now change directory, to make this
-     ./groff-<version> your working directory.
-
-  3. If you are intending to build groff with support for HTML output, then
-     you must now ensure that the prerequisites described in the later section
-     PREREQUISITES FOR HTML OUTPUT are satisfied, before proceeding to build
-     groff; in particular, please ensure that all required support programs
-     are installed in the current PATH.
-
-  4. You are now ready to configure, build, and install groff.  This is
-     accomplished using the conventional procedure, as described in the file
-     INSTALL, i.e.
-
-       ./configure --prefix=<win32-install-path> ...
-       make
-       make install
-
-     Please observe the syntax for the configure command, indicated above; the
-     default value for --prefix is not suitable for use with MinGW, so the
-     --prefix=<win32-install-path> option must be specified, where
-     <win32-install-path> is the chosen MS-Windows directory in which the
-     groff application files are to be installed (see the later section
-     entitled CHOOSING AN INSTALLATION PATH).  Any other desired configuration
-     options may also be specified, as described in the standard groff
-     installation instructions.
-
-  5. After completing the above, groff should be successfully installed; the
-     build directory is no longer required; it may be simply deleted in its
-     entirety.  Alternatively, you may choose to keep it, but to remove all
-     files which can be reproduced later, by repeating the configure, make and
-     make install steps; this is readily accomplished by the command
-
-       make distclean
-
-
-  This completes the installation of groff; please read the final sections of
-  this file, GROFF RUNTIME ENVIRONMENT and CAVEATS AND BUGS, for advice on
-  setting up the runtime environment, and avoiding known runtime problems,
-  before running groff.
-
-
-  CHOOSING AN INSTALLATION PATH
-  -----------------------------
-
-  It may be noted that the above instructions indicate that the ./configure
-  command must be invoked with an argument specifying a preference for
-  --prefix=<win32-install-path>, whereas the standard groff installation
-  instructions indicate that this may be omitted, in which case it defaults to
-  --prefix=/usr/local.
-
-  In the case of building with MinGW, the default behaviour of configure is
-  not appropriate for the following reasons.
-
-  o The MSYS environment creates a virtual UNIX-like file system, with its
-    root mapped to the actual MS-Windows directory where MSYS itself is
-    installed; /usr is also mapped to this MSYS installation directory.
-
-  o All of the MSYS tools, and the MinGW implementation of GCC, refer to files
-    via this virtual file system representation; thus, if the
-    --prefix=<win32-install-path> is not specified when groff is configured,
-    `make install' causes groff to be installed in <MSYS-install-path>/local.
-
-  o groff needs to know its own installation path, so that it can locate its
-    own installed components.  This information is compiled in, using the
-    exact form specified with the --prefix=<win32-install-path> option to
-    configure.
-
-  o Knowledge of the MSYS virtual file system is not imparted to groff; it
-    expects the compiled-in path to its components to be a fully qualified
-    MS-Windows path name (although UNIX-style slashes are permitted, and
-    preferred to the MS-Windows style backslashes, to demarcate the directory
-    hierarchy).  Thus, when configuring groff, if
-    --prefix=<win32-install-path> is not correctly specified, then the
-    installed groff application looks for its components in /usr/local, and
-    most likely doesn't find them, because they are actually installed in
-    <MSYS-install-path>/local.
-
-  It is actually convenient, but by no means a requirement, to have groff
-  installed in the /usr/local directory of the MSYS virtual file system; this
-  makes it easy to invoke groff from the MSYS shell, since the virtual
-  /usr/local/bin is normally added automatically to the PATH (the default
-  PATH, as set in MSYS's /etc/profile), when MSYS is started.
-
-  In order to install groff into MSYS's /usr/local directory, it is necessary
-  to specify the fully qualified absolute MS-Windows path to this directory,
-  when configuring groff, i.e.
-
-    ./configure --prefix=<MSYS-install-path>/local ...
-
-  For example, on a system where MSYS is installed in the MS-Windows directory
-  D:\MSYS\1.0, the MSYS virtual path /usr/local resolves to the absolute
-  MS-Windows native path D:\MSYS\1.0\local (the /usr component of the MSYS
-  virtual path does not appear in the resolved absolute native path name since
-  MSYS maps this directly to the root of the MSYS virtual file system).  Thus,
-  the --prefix option should be specified to configure as
-
-    ./configure --prefix=D:/MSYS/1.0/local ...
-
-  Note that the backslash characters, which appear in the native MS-Windows
-  form of the path name, are replaced by UNIX-style slashes in the argument to
-  configure; this is the preferred syntax.
-
-  Also note that the MS-Windows device designator (D: in this instance) is
-  prepended to the specified path, in the normal MS-Windows format, and that,
-  since upper and lower case distinctions are ignored in MS-Windows path
-  names, any combination of upper and lower case is acceptable.
-
-
-  PREREQUISITES FOR HTML OUTPUT
-  -----------------------------
-
-  If you intend to use groff for production of HTML output, then there are a
-  few dependencies which must be satisfied.  Ideally, these should be resolved
-  before attempting to configure and build groff, since the configuration
-  script does check them.
-
-  In order to produce HTML output, you first require a working implementation
-  of Ghostscript; either the AFPL Ghostscript or the GNU Ghostscript
-  implementation for MS-Windows should be suitable, depending on your
-  licensing preference.  It is highly recommended to use version 8.11 or
-  higher due to bugs in older versions.  These may be obtained, in the form of
-  self-installing binary packages, by following the download links for the
-  chosen licensing option, from http://sourceforge.net/projects/ghostscript.
-
-  Please note that these packages install the Ghostscript interpreter required
-  by groff in the ./bin subdirectory of the Ghostscript installation
-  directory, with the name gswin32c.exe.  However, groff expects this
-  interpreter to be located in the system PATH, with the name gs.exe.  Thus,
-  to ensure that groff can correctly locate the Ghostscript interpreter, it is
-  recommended that the file gswin32c.exe should be copied from the Ghostscript
-  installation directory to the MSYS /usr/local/bin directory, where it should
-  be renamed to gs.exe.
-
-  In addition to a working Ghostscript interpreter, you also require several
-  image manipulation utilities, all of which may be scavenged from various
-  packages available from http://sourceforge.net/projects/gnuwin32, and which
-  should be installed in the MSYS /usr/local/bin directory, or any other
-  suitable directory which is specified in the PATH.  These additional
-  prerequisites are
-
-    1. from the netpbm-<version>-bin.zip package:
-
-         netpbm.dll
-         pnmcrop.exe
-         pnmcut.exe
-         pnmtopng.exe
-         pnmtops.exe
-
-    2. from the libpng-<version>-bin.zip package:
-
-         libpng.dll
-
-    3. from the zlib-<version>-bin.zip package:
-
-         zlib-1.dll, which must be renamed to zlib.dll
-
-    4. from the psutils-<version>-bin.zip package:
-
-         psselect.exe
-
-  Note that it is not necessary to install the above four packages in their
-  entirety; of course, you may do so if you wish.
-
-
-  GROFF RUNTIME ENVIRONMENT
-  -------------------------
-
-  The runtime environment, provided to groff by MSYS, is essentially the same
-  as would be provided under a UNIX or GNU/Linux operating system; thus, any
-  environment variables which may be used to customize the groff runtime
-  environment have similar effects under MSYS, as they would in UNIX or
-  GNU/Linux, with the exception that any variable specifying a path should
-  adopt the same syntax as a native MS-Windows PATH specification.
-
-  There is, however, one known problem which is associated with the
-  implementation of the MS-Windows file system, and the manner in which the
-  Microsoft runtime library (which is used by the MinGW implementation of GCC)
-  generates names for temporary files.  This known problem arises when groff
-  is invoked with a current working directory which refers to a network share,
-  for which the user does not have write access in the root directory, and
-  there is no environment variable set to define a writeable location for
-  creating temporary files.  When these conditions arise, groff fails with a
-  `permission denied' error, as soon as it tries to create any temporary file.
-
-  To specify the location for creating temporary files, the standard UNIX or
-  GNU/Linux implementation of groff provides the GROFF_TMPDIR or TMPDIR
-  environment variables, whereas MS-Windows applications generally use TMP or
-  TEMP; furthermore, the MS-Windows implementations of Ghostscript apparently
-  support the use of only TEMP or TMPDIR.
-
-  To avoid problems with creation of temporary files, it is recommended that
-  you ensure that both TMP and TEMP are defined, with identical values, to
-  point to a suitable location for creating temporary files; many MS-Windows
-  boxes have them set already, and groff has been adapted to honour them, when
-  built in accordance with the preceding instructions, using MinGW.
-
-
-  CAVEATS AND BUGS
-  ----------------
-
-  There are two known issues, observed when running groff in the MinGW/MSYS
-  environment, which would not affect groff in its native UNIX environment:
-
-  o Running groff with the working directory set to a subdirectory of a
-    network share, where the user does not have write permission in the root
-    directory of the share, causes groff to fail with a `permission denied'
-    exception, if the TMP environment variable is not appropriately defined;
-    it may also be necessary to define the TEMP environment variable, to avoid
-    a similar failure mode, when using the -Thtml output mode of groff.  This
-    problem is more fully discussed in the preceding section, GROFF RUNTIME
-    ENVIRONMENT.
-
-  o When running groff (or nroff) to process standard input, where the
-    standard input stream is obtained directly from the RXVT console provided
-    with MSYS, groff cannot detect the end-of-file condition for the standard
-    input stream, and hangs.  This appears to be caused by a fault in the MSYS
-    implementation of RXVT; it may be worked around by either starting MSYS
-    without RXVT (see the comments in the MSYS.BAT startup script); in this
-    case standard input is terminated by typing <Ctrl-Z> followed by <RETURN>,
-    on a new input line.  Alternatively, if you prefer to use MSYS with RXVT,
-    you can enter the interactive groff command in the form
-
-      cat | groff ...
-
-    in which case <Ctrl-D> terminates the standard input stream, in just the
-    same way it does on a UNIX system; the cat executable provided with MSYS
-    does seem to trap the end-of-file condition, and properly signals groff
-    that the input stream has terminated.

-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

-			  [PREFIX]
-
-By default, \`make install' will install all the files in

-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.

-  CXX         C++ compiler command
-  CXXFLAGS    C++ compiler flags
-  CPP         C preprocessor
-

-   Here is a matrix of mmap possibilities:
-	mmap private not fixed
-	mmap private fixed at somewhere currently unmapped
-	mmap private fixed at somewhere already mapped
-	mmap shared not fixed
-	mmap shared fixed at somewhere currently unmapped
-	mmap shared fixed at somewhere already mapped
-   For private mappings, we should verify that changes cannot be read()
-   back from the file, nor mmap's back from the file at a different
-   address.  (There have been systems where private was not correctly
-   implemented like the infamous i386 svr4.0, and systems where the
-   VM page cache was not coherent with the file system buffer cache
-   like early versions of FreeBSD and possibly contemporary NetBSD.)
-   For shared mappings, we should conversely verify that changes get
-   propagated back to all the places they're supposed to be.
-
-   Grep wants private fixed already mapped.
-   The main things grep needs to know about mmap are:
-   * does it exist and is it safe to write into the mmap'd area
-   * how to use it (BSD variants)  */

-.TH EQN2GRAPH @MAN1EXT@ "@MDATE@" "Groff Version @VERSION@"
-.IX eqn2graph
-.SH NAME
-eqn2graph \- convert an EQN equation into a cropped image
-.
-.
-.SH SYNOPSIS
-.B eqn2graph
-[
-.B \-unsafe
-]
-[
-.BI \-format\  fmt
-]
-.
-.
-.SH DESCRIPTION
-Reads an EQN equation (one line) as input; produces an image
-file (by default in Portable Network Graphics format) suitable for the
-Web as output.
-.P
-Your input EQN code should \fInot\fR have the \&.EQ/.EN preamble that
-that normally precedes it within 
-.BR groff (@MAN1EXT@) 
-macros; nor do you need to have dollar-sign or other delimiters
-around the equation.
-.P
-The output image will be a black-on-white graphic clipped to the
-smallest possible bounding box that contains all the black pixels.
-By specifying command-line options to be passed to 
-.BR convert (1)
-you can give it a border, set the background transparent, set the
-image's pixel density, or perform other useful transformations.
-.P
-This program uses 
-.BR @g@eqn (@MAN1EXT@),
-.BR groff (@MAN1EXT@),
-and the ImageMagick 
-.BR convert (1)
-program.
-These programs must be installed on your system and accessible on your
-$PATH for \fBeqn2graph\fR to work.
-.
-.
-.SH OPTIONS
-.TP
-.B \-unsafe
-Run 
-.BR groff (@MAN1EXT@)
-in the `unsafe' mode enabling the PIC macro
-.B sh
-to execute arbitrary commands.
-The default is to forbid this.
-.TP
-.BI \-format\  fmt
-Specify an output format; the default is PNG (Portable Network Graphics).
-Any format that
-.BR convert (1)
-can emit is supported.
-.PP
-Command-line switches and arguments not listed above are passed to
-.BR convert (1).
-.
-.
-.SH FILES
-.Tp \w'\fB@MACRODIR@/eqnrc'u+2n
-.B @MACRODIR@/eqnrc
-The 
-.BR @g@eqn (@MAN1EXT@)
-initialization file.
-.
-.
-.SH ENVIRONMENT
-.TP
-.B GROFF_TMPDIR
-The directory in which temporary files will be created.
-If this is not set
-.B eqn2graph
-searches the environment variables
-.BR \%TMPDIR ,
-.BR TMP ,
-and
-.B TEMP
-(in that order).
-Otherwise, temporary files will be created in
-.BR /tmp .

-# eqn2graph -- compile EQN equation descriptions to bitmap images
-#
-# by Eric S. Raymond <esr@thyrsus.com>, July 2002
-#
-# In Unixland, the magic is in knowing what to string together...
-#
-# Take an eqn equation on stdin, emit cropped bitmap on stdout.
-# The pic markup should *not* be wrapped in .EQ/.EN, this script will do that.
-# A -U option on the command line enables gpic/groff "unsafe" mode.
-# A -format FOO option changes the image output format to any format
-# supported by convert(1).  All other options are passed to convert(1).
-# The default format is PNG.
-#
-# This is separate from pic2graph because pic processing has some weird
-# clipping effect on the output, mangling equations that are very wide 
-# or deep.  Besides, this tool can supply its own delimiters.
-#
-
-# Requires the groff suite and the ImageMagick tools.  Both are open source.
-# This code is released to the public domain.
-#
-# Here are the assumptions behind the option processing:
-#
-# 1. None of the options of eqn(1) are relevant.
-#
-# 2. Only the -U option of groff(1) is relevant.
-#
-# 3. Many options of convert(1) are potentially relevant, (especially 
-# -density, -interlace, -transparency, -border, and -comment).
-#
-# Thus, we pass -U to groff(1), and everything else to convert(1).

-gdiffmk is approximately a recreation of the original Bell Labs/AT&T diffmk
-command for troff/nroff documents, with enhancements.
-
-It should not be confused with `diffmk' commands that operate on XML.
-
-The inspiration for this code was a Perl 2 version written in 1989 by Randal
-L. Schwartz.  See
-  landfield.com/software/comp.sources.misc/archive-name/volume06/diffmk.p.gz
-
-The command also attempts to reproduce some of the functionality of the old
-`nrchbar' command.  See
-  open-systems.ufl.edu/mirrors/ftp.isc.org/usenet/comp.sources.unix/volume10/nrchbar.Z
-
-Thanks to Werner Lemberg for help in making the package more portable and
-fit into the GNU groff source structure.
-
-Gnu diff(1) with the -Dname option does all of the work and sed(1)
-translates the output into something groff/troff/nroff can handle.
-
-Note the BUGS on the man page.
-
-The `tests' directory contains simple tests.  `runtests run' runs them and
-compares the output against baseline files.  Calling `runtests' without
-argument gives the usage.

-.SH DESCRIPTION
-.B gdiffmk
-compares two
-.BR groff (1),
-.BR nroff (1),
-or
-.BR troff (1)
-documents,
-.I file1
-and
-.IR file2 ,
-and creates an output which is
-.I file2
-with added `margin character' (.mc) commands that indicate the differences.
-.
-.LP
-If the
-.I output
-filename is present,
-the output is written there.
-If it is
-.B \-
-or absent the output is written to the standard output.
-.
-.LP
-If the
-.I file1
-or
-.I file2
-argument is
-.B \-
-the standard input is read for that input.
-Clearly both cannot be
-.BR \- .
-.
-.LP
-Note that the output is not necessarily compatible with all macro packages
-and all preprocessors.
-See the
-.B BUGS
-section below.
-.
-.
-.SH OPTIONS
-.TP
-.BI \-a addmark
-Use the
-.I addmark
-for source lines not in
-.I file1
-but present in
-.IR file2 .
-Default:
-.BR + .
-.
-.TP
-.B \-B
-By default, the deleted texts marked by the
-.B \-D
-option end
-with an added troff break command,
-.BR .br ,
-to ensure that the deletions are marked properly.
-This is the only way to guarantee that deletions and small
-changes get flagged.
-This option directs the program not to insert these breaks; it makes no
-sense to use it without
-.BR \-D .
-.
-.TP
-.BI \-c changemark
-Use the
-.I changemark
-for changed source lines.
-Default:
-.BR | .
-.
-.TP
-.BI \-d deletemark
-Use the
-.I deletemark
-for deleted source lines.
-Default:
-.BR * .
-.
-.TP
-.B \-D
-Show the deleted portions from changed and deleted text.
-Default delimiting marks:
-.BR "[[" " .\&.\&.\&. " "]]" .
-.
-.TP
-.BI \-M "mark1 mark2"
-Change the delimiting marks for the
-.B \-D
-option.
-It makes no sense to use this option without
-.BR \-D .
-.
-.TP
-.BI \-x diffcmd
-Use the
-.I diffcmd
-command to perform the comparison of
-.I file1
-and
-.IR file2 .
-In particular,
-.I diffcmd
-should accept the GNU
-.B diff
-.BI \-D name
-option.
-Default:
-.BR diff (1).
-.
-.TP
-.B \-\-
-All the following arguments are treated as file names,
-even if they begin with
-.BR \- .
-.
-.TP
-.B \-\-help
-Print a usage message on standard error output and exit.
-.
-.TP
-.B \-\-version
-Print version information on the standard output and exit.
-.
-.
-.SH BUGS
-The output is not necessarily compatible with all macro packages
-and all preprocessors.
-A workaround that is often successful against preprocessor problems
-is to run
-.B gdiffmk
-on the output of all the preprocessors instead of the input source.
-.
-.LP
-.B gdiffmk
-relies on the
-.BI \-D name
-option of GNU
-.BR diff (1)
-to make a merged `#ifdef' output format.
-It hasn't been tested whether other versions of
-.BR diff (1)
-do support this option.
-See also the
-.BI \-x diffcmd
-option.
-.
-.LP
-Report bugs to bug-groff@gnu.org.
-Include a complete, self-contained example that will allow the bug to
-be reproduced, and say which version of
-.B gdiffmk
-you are using.

-.TH GRAP2GRAPH @MAN1EXT@ "@MDATE@" "Groff Version @VERSION@"
-.IX grap2graph
-.SH NAME
-grap2graph \- convert a grap diagram into a cropped bitmap image
-.
-.
-.SH SYNOPSIS
-.B grap2graph
-[
-.B \-unsafe
-]
-[
-.BI \-resolution\  M\fR|\fPMxN
-]
-[
-.BI \-format\  fmt
-]
-.
-.
-.SH DESCRIPTION
-Reads a grap program as input; produces an image file (by default in
-Portable Network Graphics format) suitable for the Web as output.
-For a description of the grap language, see
-.BR grap (1).
-.P
-Your graph specification should \fInot\fR be wrapped with the \&.G1 and
-\&.G2 macros that normally guard it within
-.BR groff (@MAN1EXT@)
-macros.
-.P
-The output image will be a black-on-white graphic clipped to the
-smallest possible bounding box that contains all the black pixels.
-By specifying command-line options to be passed to 
-.BR convert (1)
-you can give it a border, set the background transparent, set the
-image's pixel density, or perform other useful transformations.
-.P
-This program uses 
-.BR grap (1),
-.BR @g@pic (@MAN1EXT@),
-.BR groff (@MAN1EXT@),
-and the ImageMagick 
-.BR convert (1)
-program.
-These programs must be installed on your system and accessible on your
-$PATH for \fBgrap2graph\fR to work.
-.
-.
-.SH OPTIONS
-.TP
-.B \-unsafe
-Run 
-.BR @g@pic (@MAN1EXT@)
-and
-.BR groff (@MAN1EXT@)
-in the `unsafe' mode enabling the PIC macro
-.B sh
-to execute arbitrary commands.
-The default is to forbid this.
-.TP
-.BI \-format\  fmt
-Specify an output format; the default is PNG (Portable Network Graphics).
-Any format that
-.BR convert (1)
-can emit is supported.
-.PP
-Command-line switches and arguments not listed above are passed to
-.BR convert (1).
-.
-.
-.SH ENVIRONMENT
-.TP
-.B GROFF_TMPDIR
-The directory in which temporary files will be created.
-If this is not set
-.B grap2graph
-searches the environment variables
-.BR \%TMPDIR ,
-.BR TMP ,
-and
-.B TEMP
-(in that order).
-Otherwise, temporary files will be created in
-.BR /tmp .
-.

-# grap2graph -- compile graph description descriptions to bitmap images
-#
-# by Eric S. Raymond <esr@thyrsus.com>, May 2003
-#
-# In Unixland, the magic is in knowing what to string together...
-#
-# Take grap description on stdin, emit cropped bitmap on stdout.
-# The pic markup should *not* be wrapped in .G1/.G2, this script will do that.
-# A -U option on the command line enables gpic/groff "unsafe" mode.
-# A -format FOO option changes the image output format to any format
-# supported by convert(1).  All other options are passed to convert(1).
-# The default format is PNG.
-#
-
-# Requires the groff suite and the ImageMagick tools.  Both are open source.
-# This code is released to the public domain.
-#
-# Here are the assumptions behind the option processing:
-#
-# 1. None of the options of grap(1) are relevant.
-#
-# 2. Only the -U option of groff(1) is relevant.
-#
-# 3. Many options of convert(1) are potentially relevant, (especially 
-# -density, -interlace, -transparency, -border, and -comment).
-#
-# Thus, we pass -U to groff(1), and everything else to convert(1).

-	* groffer2.sh:
-	- man_do_filespec(): Use $_OPT_SECTIONS of --sections instead of
-	$_MAN_AUTO_SEC if non-empty.  If a section was given on the
-	filespec parameter $_OPT_SECTIONS is ignored.  This differs from
-	`man' which always uses the restricted sections of --sections.
-	This function works for both normal man page search and whatis.
-	- apropos_filespec(): Use --sections for --apropos, but not for
-	--apropos-* because these provide already their own sections.
-
-	### wildcards in filespec arguments
-
-	* groffer2.sh: Wildcards are now accepted.  In `--apropos*' and
-	`--whatis' they are interpreted as wildcard search elements; but
-	in normal display they are only handled as their own character.
-
-	### development; new option
-
-	* groffer2.sh:
-	- --print: New option that prints just its argument for parameter
-	check.
-	- usage(): Add new option.
-	- $_OPT_DO_NOTHING: New variable for do_nothing().  Handle it at
-	the end of main_parse_Args().
-
-	* groffer.man: Add information on --print.
-
-	### safe exit
-
-	* groffer2.sh:
-	- error(): Always exit with $_ERROR.
-	- exit_test(): New function to exit when first exit was hidden by
-	().  Call it after each $().
-
-	### automatic shell determination
-
-	* groffer.sh:
-	- If no option --shell is given perform a test of several shells
-	to automatically start some shell for groffer2.sh.  `ksh' is used
-	first because it can be safely terminated by Ctrl-C.
-	- This can be cancelled by providing --shell=''.
-	- Add test on `sed' program.
-
-	* groffer.man: Revise information on --shell.
-
-	### trap
-
-	* groffer2.sh:
-	- trap_set(): Remove argument.  Instead of $_ALL_EXIT use only
-	signal 0.
-	- trap_unset(): Rename trap_clean().  Instead of $_ALL_EXIT use
-	only signal 0.
-	- $_ALL_EXIT: Remove this variable.
-	- Replace all direct `trap' calls by trap_set().
-	
-	* README_SH: New section `Bugs' on `trap'..
-
-	### user errors, error output without function stack
-
-	* groffer2.sh:
-	- error_user(): New function for user errors.
-	- error(): Remove call of clean_up() because the trap will do it
-	with the exit.  Remove the `kill' commands.  Create a temporary
-	file `.error' that can be tested by exit_test() for a better exit
-	test (especially for shell `ksh').
-	- $_DEBUG_USER_WITH_STACK: New variable to enable function stack
-	output in error_user().
-	- list_from_cmdline(), list_single_from_abbrev(), main_set_mode():
-	Use error_user().
-
-	### test modes on X and tty
-
-	* groffer2,sh:
-	- is_X(), is_not_X(): New functions for checking on X Window.
-	- $_VIEWER_HTML_TTY, $_VIEWER_HTML_X: New variables that split
-	$_VIEWER_HTML.  Add `galeon'.
-	- main_parse_args(): Allow mode change for graphical modes only
-	when in X Window.
-	- _do_display() of main_display(): Create a special run for
-	viewers that run on the terminal; `lynx' is the only one so far.
-
-	### add $GROFFER_MODE to command line
-
-	* groffer.sh:
-	- After the handling of the configuration files integrate
-	$GROFFER_OPT to the command line.
-	- This makes a `set' in the shell determination unnecessary.
-
-	* groffer2.sh:
-	- The debug test gets simpler because quotes are vanished without
-	$GROFFER_OPT.
-	- main_parse_MANOPT(): Prepend $mpm_list to the command line.
-	- main_parse_args(): `set' is unnecessary.
-
-	### debug; new options
-
-	* groffer2.sh:
-	- --debug-all, --debug-lm, --debug-params, --debug-shell,
-	--debug-stacks, --debug-tmpdir, --debug-user: New options.
-	- --debug: Enable all debug variables except $_DEBUG_STACKS and
-	$_DEBUG_LM.  By the new options the smallest abbreviation is now
-	`--debug'.
-	- $_DEBUG_STACKS: Rename $_DEBUG.
-	- $_DEBUG_PRINT_TMPDIR: New debug variable for printing the name
-	of the temporary directory in main_init().
-	- $_OPT_DEBUG: Remove this variable because debug is handled at
-	the early part of the script.
-	- clean_up(): Enlarge $_DEBUG_KEEP_FILES to not deleting the
-	temporary directory.
-	- usage(): Move all development options on a section of its own.
-	- Move the test of rudimentary shell functionality at the
-	beginning of the script.  Add test on `sed'.
-	- Follow this by the debug section.  The determination of all
-	--debug* options can be done without a function.
-
-	* groffer.man: Revise information on --debug and add new options.
-
-	### variables
-
-	* groffer.sh:
-	- $_ERROR: Move the definition of this variable here.
-	- $_GROFF_VERSION: New variable, is set over @...@ construct.
-	- $_OUTPUT_FILE_NAME: Move this variable to groffer2.sh.
-
-	* groffer2.sh:
-	- $_MAN_AUTO_SEC_LIST: Rename $_MAN_AUTO_SEC because it represents
-	a list.
-	- $_MAN_AUTO_SEC_CHARS: New read-only variable for storing
-	$_MAN_AUTO_SEC_LIST in [] construct.  Use it in man_do_filespec()
-	and whatis_filename().
-	- $_SPACE_CASE: New read-only variable with [] on space characters
-	with \ for `case' patterns.  Use it in several functions.
-	- $_SPACE_SED: New read-only variable with [] on space characters
-	for `sed'.  Use it in several functions.
-
-	### options and display
-
-	* groffer2.sh:
-	- list_from_cmdline(): Add test whether the same abbreviation is
-	part of long options with and without arguments.  Give handling of
-	`=' a `case' pattern of its own.
-	- main_display(): Remove unnecessary calls of `clean_up' in order
-	to use `mozilla' without problems.  In _do_display(): Fix -X by
-	providing a different process when $_DISPLAY_PROG is empty.
-	- main_set_mode(): Accept options for viewers as is, without check
-	for program.  Add test whether no program is given for a mode.
-	This avoids unnecessary empty $_DISPLAY_PROG in main_display().
-
-	### viewer programs that run on the terminal (tty); new options
-
-	* groffer2.sh:
-	- $_VIEWER_TERMINAL: New variable that stores whether a viewer was
-	supposed to run on tty.
-	- --dvi-viewer-tty, --html-viewer-tty, --pdf-viewer-tty,
-	--ps-viewer-tty, --tty-viewer-tty, --X-viewer-tty, --x-viewer-tty,
-	--www-viewer-tty: New options for viewers that run on a terminal.
-	- main_parse_args(), _do_display() of main_display(): Use the new
-	options and the new variable.
-	- usage(): Add the new options.
-
-	* groffer.man: Add information on options --*-viewer-tty.
-
-	### other fixes
-
-	* groffer2.sh:
-	- _do_display() of main_display(): Bear errors of `groff' run.
-	- is_not_file: Fix to have exactly one argument.
-	- is_not_prog(): Handle no arguments.
-	- list_has_not(): Fix.
-	- main_do_fileargs(): Remove $mdfa_exitcode.
-	- register_title(): Limit title to 4 elements.
-	- version(): Print the version information to standard output just
-	like `groff' does.
-	- --no-special: New option to disable former calls of `--all',
-	`--apropos*', and `whatis.
-	- --title: Make it an option with argument.

-	* release of groffer 0.9.21
-
-2005-08-02  Bernd Warken
-
-	### @...@ constructs
-
-	* groffer.sh:
-	- $_AT: New variable for `@'.
-	- @...@: Replace the @...@ constructs by variables _AT_..._AT.
-	These constructs are transformed by `make' to useful information.
-	Keep all of these constructs in the first part of groffer.sh.  For
-	a run before a `make' call, the script sets these variables to
-	special values for testing purpose.
-	- $_GROFFER_LIBDIR: Variable pointing to the groffer library
-	directory @libdir@/groff/groffer.
-
-	### Configuration files
-
-	* groffer.sh:
-	- Add test for `$()' construct.
-	- Read and transform the configuration files and execute the
-	emerging commands.  The `sed' script was heavily enlarged to
-	handle line with spaces and quotes.  The emerging script is now
-	called by `eval', so no temporary file is needed.
-	- $_CONF_FILE_ETC, $_CONF_FILE_HOME: New variables for the config
-	files.
-	- $_SQ, $_SP: Move variables for characters before the handling of
-	the configuration files.  Rename $_SQUOTE to $_SQ and $_SPACE to
-	$_SP.
-	- $GROFFER_OPT: Remove cleaning of this variable before the
-	reading of the configuration files.
-
-	* groffer2.sh:
-	- main_init(): Remove the getting of the configuration files.
-
-	### Rewrite the shell determination
-
-	* groffer.sh:
-	- Get rid of all functions in `groffer.sh'.  Rewrite the shell
-	determination with `` and $().
-	- --shell: Shortest abbreviation is `--sh'.  Allow arguments for
-	the shell name.
-	- Allow an empty argument for --shell as shell name to overwrite a
-	specified shell; an empty shell name gets back to the default
-	shell.
-	- The shell determination now inludes the full handling of the
-	config files.  The `--shell' option needs no longer a line
-	starting with `-'.
-
-	### Test of unset
-
-	* groffer.sh:
-	- Remove test of `unset'.
-	- Remove all calls of `unset'.
-	- Use one character names for all variables that are meant to be
-	local in this script.
-
-	* groffer2.sh:
-	- Move the test of `unset' to the testing of rudimentary shell
-	functionality without change.
-
-        ### Allow abbreviations for long options
-
-	* groffer2.sh:
-	- list_has_abbrev(): New function for checking a list having an
-	element with a given abbreviation.
-	- list_get_single_from_abbrev(): New function to retrieve the
-	element having a given abbreviation.
-	- list_from_cmd_line(): For an option abbreviation determine the
-	corresponding long option.
-	- From the man option lists remove the elements that are also in
-	a groffer list.
-	- Allow abbreviation for the early test of --debug.
-
-	* groffer.sh: Allow abbreviation for the early test on --shell.
-	- get_opt_shell(): Rewrite _get_opt_shell() and the shell test
-	around it.
-	- test_on_shell(): Rename function _test_on_shell().
-	- $_SHELL: global variable for the shell to run groffer2.sh.
-
-	### Get rid of `sh -c'
-
-	* groffer2.sh:
-	- main_display(), _do_display(): Remove the `sh -c' calls.  Make
-	the cleanup working without it.
-	- _do_display(): Extend _do_display() such that	it can be used for
-	the pdf mode as well.
-	- _make_pdf(): New subfunction of main_display() for running the
-	additional parts of pdf mode in _do_display().
-	- rm_file(), rm_file_with_debug(), rm_tree(): New functions for
-	removing files and directories.
-
-	### Change directory
-
-	* groffer2.sh:
-	- $_START_DIR: New variable to store the directory at the starting
-	time of the script.
-	- main_display(): Go to the groffer temporary directory to be able
-	to process internal `groff' data like pictures.
-	- clean_up(): Get back to the starting directory.
-
-	### Compatibility with strange shells
-
-	* groffer2.sh:
-	- clean_up(): `zsh' and `posh' had difficulties with `eval'.
-	- is_*(): Add test on empty argument.  Some shells return true on
-	`test -d' etc. with empty argument, while most shells return
-	false.
-	- echo1(); New function to print single line `cat <<EOF'.  Replace
-	all `echo x' by `echo1'.
-	- list_has_abbrev(), list_from_cmdline(): Correction.
-	- main_parse_MANOPT(): Repair and revise.
-	- --do-nothing: New option without output (for development).
-	- Rewrite rudimentary shell functionality near the beginning of
-	the script.
-
-	* groffer.sh, groffer2.sh:
-	- Remove `;' after the commands `if', `while', and `until'.
-
-	### Debugging information
-
-	* groffer2.sh:
-	- $_DEBUG_PRINT_PARAMS: New variable for printing all parameters
-	from the config files, $GROFFER_OPT, and command line after they
-	have been transformed.
-	- $_DEBUG_PRINT_SHELL: New variable for printing the name of the
-	shell found in groff.sh.
-	- main(): Move the landmarks of main-*() into main().
-
-	### Further checks and additions
-
-	* groffer.sh, groffer2.sh:
-	- $_PROGRAM_NAME: Replace this variable by `groffer'.  The program
-	name is now stable.
-	- $_GROFFER_RUN: Remove this variable.  As `groffer.sh' or
-	`groffer' is no longer rerun, this variable is not necessary any
-	more.
-
-	* groffer2.sh:
-	- main_set_resources(): Make the default viewers capable to use
-	arguments in the list.
-	- leave(): Add an argument for given exit code.  Use it where
-	suitable in main_*().
-	- do_filearg(): Add error messages for non-existing files and man
-	pages.
-	- _do_opt_V(): New subfunction of main_display() to handle the
-	output for option `-V'.  `groff -V' is greatly enlarged by
-	`groffer' specific information.
-	- register_title(): Handle file names with spaces.  Replace spaces
-	by `_'.
-	- is_existing(): Add `test -c' for special files.
-	- usage(): Add `=arg' to the options with an argument.  Add option
-	`--tty-viewer'.
-	- kghostview: In the default viewer list, add option
-	`--scale=1.45'.
-	- $_OPTS_CMDLINE_SHORT_NA: Correct a lacking space.
-

-
-	### Split groffer.sh into two files groffer.sh and groffer2.sh.
-
-	* groffer.sh:
-	- Remove the second part of this script.  It is now in
-	groffer2.sh.
-	- $_GROFFER2_SH: New variable to point to the installed position
-	of `groffer2.sh'.  This position is presented using @libdir@.
-
-	* groffer2.sh: New script containing the second part of
-	groffer.sh. This script will be installed in the groffer library
-	directory @libdir@/groff/groffer, this might be
-	/usr/local/lib/groff/groffer/groffer2.sh for example.
-
-	* Makefile.sub:
-	- `groffer': Add replacement of @libdir@.
-	- `install_data': Add the installation of the groffer library
-	directory and groffer2.sh.
-	- `uninstall_sub': Delete the installed `groffer2.sh' and the
-	groffer library directory.
-
-	* README_SH:
-	- Remove the function list.

-	- Documentation of the splitting of the script.
-	- Document the possible abbreviation of options.
-
-	________________________________________________________________
-	* release of groffer 0.9.19
-
-2005-07-07  Bernd Warken
-
-	* groffer.sh: extensions
-	- `mode x': Mode for the equivalent options `--x', `--mode x',
-	`--X' `--mode X', and the default mode.  The default assumes a
-	resolution of 75 dpi.  The default device for a resolution of 75
-	dpi is `X75-12', the default device for a resolution of 100 dpi is
-	`X100'.  The default geometry for the resolution of 100 dpi is set
-	to the width 800 dpi.
-	- `mode X': New mode for option -X only.
-	- `-V': Extent the `groff' output of -V by `groffer' specific
-	information (in main_display()).
-	- register_file(): Replace title `-' by `stdin'.
-	- $_DEBUG_KEEP_FILES: If set to `yes' the files in the temporary
-	directory are not deleted before the end trap.
-
-	* groffer.sh: get `zsh' to work as well
-	- tmp_create(): Use `: >file' for generating an empty file.
-	- rmdir: Replace `rmdir' by `rm -f -r'.
-	- eval: Add `eval' to many commands with variable arguments.
-
-	* groffer.sh: repair `debug'
-	- Print all debug output to stderr.
-	- $_FUNC_STACK: Built function call stack even when $_DEBUG is not
-	set.  Now the arguments are not added.
-	- $_DEBUG: If set to `yes' print 3 call stack events: the function
-	that is added with its arguments is printed with `+++ '
-	(func_push()); the call stack after the addition is printed with
-	`>>> ' (func_push()); the call stack after the removing is printed
-	with `<<< ' (func_pop()).
-	- error(): Always print the function call stack on errors.
-
-	* groffer.sh: Corrections
-	- $_groffer_run: Rename to $_GROFFER_RUN.
-	- $unset: Rename to $_UNSET.
-	- Repair test of `unset'.
-	- Repair test for `--shell'.  The script is now rerun under the
-	shell specified in the option argument.  This can increase the
-	speed.
-
-	* README_SH: `zsh' now works.
-
-	* groffer.man:
-	- Reformulate the information for the `groffer' specific details
-	of option `-V'.
-	- Add information on the debug process.
-	- Add information on the default devices in `x mode'.
-	- Minor corrections.
-
-	________________________________________________________________
-	* release of groffer 0.9.18
-
-2005-07-01  Bernd Warken
-
-	* groffer.sh: further shell compatibility
-	- `echo': Remove options and possible options of `echo' by
-	preceding the argument with a character `x' that is removed by
-	`sed' or replace `echo' by `cat <<EOF'.  `echo -n' seems to be not
-	portable, so it is omitted.
-	- `for': Remove `;' from within `for' (because of ksh).
-	- `ls': Old UNIX systems echoed the error message to standard
-	output.  So handle the output with `sed'.  If the output contains
-	`not found' map it to an empty string.
-	- `true': Replace `true' by command `:'.  Remove test of `true'
-	(because `ash' refuses the redefinition of builtins even in an
-	unreachable `if' branch).
-	- `false': Remove test of `false'; it isn't used any more.
-	- `test': As `test -e' does not exist in Solaris 2.5 replace it by
-	`test -f || test -d'.
-	- `unset': `unset' is said to be not portable.  As `ash' protests
-	against the definition of the function `unset()' in the test of
-	`unset' replace the test by defining `$unset' to `unset' if it
-	exists and to `:' otherwise.  Use `eval $unset' instead of the
-	direct command `unset'.
-	- _get_opt_shell(): Replace `for' loop with `shift' by `while'.
-	- man_search_section(): Replace `for f in filename*' by a test on
-	the existence of `filename*'.
-	- `zsh' interprets `$...'  as `"$..."'.  So `eval' must be called;
-	This cannot be used in `for i in $f', so it must be rewritten as
-	`for i in $(eval set x $f; shift; echo "$@")'
-
-	* groffer.sh:
-	- `--X', `--x', `--mode=X', `--mode=x': Make these options
-	equivalent to choosing an X device by setting `-TX75-12'.  `-X' is
-	still equivalent to `groff -X'.
-	- main_init(): Choose the name of the temporary file by adding a
-	number using `expr' if it exists and cannot be removed.
-	- main_parse_args():Repair some options by replacing `$mpa_mode'
-	by `$_OPT_MODE'.
-	- catz(): Rename it to cat_z() to avoid problem with existing
-	programs.
-	- where(): Rename to where_is().
-	- $_CONFFILES: Rename to $_CONF_FILES.
-	- $_HAS_BZIP: export and preset it.
-
-	* groffer.man:
-	- Document the `X mode' changes.
-	- Add `@g@' to `troff'.
-
-	* README, README_SH, TODO:
-	- Add date line `Latest update:'.
-	- Add `...' quoting to essential terms.
-	- Add Emacs mode at the end.
-
-	* README_SH:
-	- Add documentation on the above compatibility changes.
-	- Add documentation on used commands.
-	- Mention the tested shells.
-
-	* Makefile.sub:
-	Readd `@g@'.

-2005-06-23  Bernd Warken
-
-	* groffer.sh: get rid of `local' in functions (it is not POSIX)
-	- Replace local variables by variable names with a special prefix
-	that is an abbreviation of the corresponding function name (quasi-
-	local variables).
-	- Unset the quasi-local function variables before returning.
-	- _t_e_s_t_f_u_n_c_(): Remove tests for local and global
-	variables.
-	- Add quasi-local variables for saving the content of
-	single-character variables.
-	- Remove some unused local and global variables.
-	- Several variables were forgotten to make local.  They are now
-	made quasi-local.
-
-	* groffer.sh: other corrections
-	- $return_var: New function (after `eval') for an arbitrary
-	return value.
-	- obj*(): Add return modes.
-	- Rewrite tests for `true' and `false'.
-	- Add function names to error calls where it was forgotten.
-	- `for': Replace `for x in "$@"' by `for x'.
-	- `set': Replace `set -- ...' by `set x ...; shift'.
-	- `sed': Replace `\|.*|s|...|...|' by `s|...|...|'.
-
-	* README_SH:
-	- Add information on the removing of `local'.
-	- New section for non-POSIX shell restrictions.

-	user.  If the directory already exists and cannot be removed then
-	append `X' to the directory name.
-	- is_non_empty_file(): fix it to use POSIX `test -s'.

-	- list_from_cmdline(): Simplify the arguments.
-	- As $POSIXLY_CORRECT is internally set to `y' by some GNU
-	`/bin/sh' shells the following 2 fixes are necessary:
-	-- `sed': Empty patterns are not allowed with $POSIXLY_CORRECT
-	set; so move the address information before the `s' command to the
-	pattern after the command, and write `.*' to the address field.

-	to finish the option processing after the first non-option
-	argument; use the flexible GNU mixing of options and file names
-	instead.

-2004-04-24  Bernd Warken
-	________________________________________________________________
-	* release of groffer 0.9.5
-
-	This version is a rewrite of groffer in many parts, but it is kept
-	in the old single script style.
-
-	Overview of new options:
-	--text, --mode text, --tty-viewer,
-	--X, --mode X, --X-viewer, --html, --mode html, --html-view,
-	--apropos-data, --apropos-devel, --apropos-progs
-
-	New file:
-	<groffer-source>/README_SH
-
-
-	******* Extension of the `apropos' handling
-
-        The output of man's `apropos' has grown immensely meanwhile, so it
-	has become inefficient.  Now `groffer' provides new options to get
-	the a selected information from this output.
-
-	* groffer.sh:
-        `--apropos-progs': new option for displaying only information
-        on programs (man page sections 1, 6, and 8)
-        `--apropos-data': new option for displaying only information
-        on documented data (man page sections 4, 5 and 7)
-        `--apropos-devel': new option for displaying only information
-        on development documentation (man page sections 2, 3 and 9)
-        `--apropos': still displays just the output of man's `apropos'
-	program.
-	- Specify all of these options as a single argument option; that
-	makes groffer's `--apropos' option slightly different because
-	the corresponding `man' option does not have arguments,	but takes
-	all file arguments as apropos targets.  So just ignore the `man'
-	options `-k' and `--apropos' in the parsing of $MANOPT.
-	- Exit after processing one `apropos' call.
-
-
-	******* Quasi object oriented function arguments
-
-	An object is the name of an environment variable.  The value of
-	this variable contains the object's content.  This allows to
-	specify function arguments and the calling syntax in a simpler way
-	by letting the first argument be a variable name, usable for input
-	or output.
-
-	Such an object type is `list', the string value of a shell
-	variable arranged in space-separated single-quoted elements, such
-	as $GROFFER_OPT internally.
-
-	* groffer.sh:
-	- Remove list_from_args(), list_element_from_arg()
-	list_from_lists(), list_length(), and list_prepend().
-	They can be replaced by list_append().
-	- All list*() functions are rearranged such that the first
-	argument is a list object, the name of a variable.
-
-
-	******* Simplification of configuration files
-
-	The new syntax of the groffer configuration files is
-	- all lines starting with a `-' character are interpreted as
-	command line options for all calls of groffer; they are collected
-	and prepended to the actual value of $GROFFER_OPT; optional
-	spaces at the beginning.of the line are omitted.
-	- all other lines are interpreted as a shell command and executed
-	in the current shell of the groffer call.
-
-	Precedence:
-	- The command line and the external environment variables such as
-	$GROFFER_OPT of the groffer call have the highest precedence.
-	- This is overwritten by the configuration file in the user's home
-	directory.
-	- The system configuration file in /etc has the lowest
-	precedence.
-
-	* groffer.sh:
-	The configuration files are now called after the determination of
-	the temporary files in main_init().
-
-
-	******* Script file name
-
-	The file name of the script is needed for the several calls during
-	the search for the optimal shell.
-
-	* groffer.sh:
-	- $_GROFFER_SH: replace $_this by $_GROFFER_SH and use $0 for
-	determining the file name of the script for the following calls,
-	instead of the cumbersome @BINDIR@ construction.
-	- Force the script to be called as an executable file, so $0 must
-	contain the program name.
-
-
-	******* Improved temporary file names
-
-	Just like groff, groffer mixes all file parameters into a single
-	output file.  Its name is now constructed as a comma-separated
-	list built from the file name arguments without a leading comma.
-	So a leading comma can be used for the internal temporary file
-	names.
-
-	* groffer.sh:
-	- $_OUTPUT_FILE_NAME: new global variable as basis for the output
-	file name; it is set in main_set_resources().
-        - tmp_create(): use `,name' for temporary files different from
-	output file because the output file name does not start with a
-	comma.  `$$' is not needed anymore.
-	- main_display(): simplification of $_modefile in _do_display()
-	and single display modes.
-	- Add extension `.html' to output file name in html mode.
-	- base_name(): correction for strange positions of `/'.
-
-
-	******* Mode fixes
-
-	* groffer.sh:
-	- Set the main default mode to `x' with groff's	X Window viewer
-	`gxditview'.
-	- Allow 'x' and 'X' in `--mode' for the X Window mode; the same
-	for `--x' and `X', `--x-viewer' and `--X-viewer'.
-	- Make groff's `-X' equivalent to `mode X'.
-	- Fix `--auto', `--mode auto',  and `--default-modes'.
-	- `html' mode: new mode equivalent to `www', add `konqueror' and
-	`lynx' as viewers.
-	- `pdf' mode: fix zoom options for pdf-viewer `xpdf' in
-	main_set_resources(); in main_display() fix the display structure.
-	- Set default X Window resolution to 75dpi.  This is not optimal,
-	but with a higher value the options and resources for some viewers
-	must be optimized.
-	`--text' and `--mode text': new option for text output without a
-	pager.
-	- `--tty-viewer': new option equivalent to `--pager'.
-	- Correct the pagers for `tty' mode.
-	- Fix `groff' mode in main_set_resources() and main_display().
-	- Harmonize `--mode arg' with the equivalent options `--arg'.
-
-
-	******* Fixes for command line options
-
-	* groffer.sh:
-	- list_from_cmdline(): fix the parsing of options with arguments.
-	- Rename $_OPT_TTY_DEVICE to $_OPT_TEXT_DEVICE.
-	- $_OPTS_X_*: new variables for the inhereted X Window variables.
-	- Improve the distribution of the command line options into
-	$_OPTS_GROFFER_*, $_OPTS_GROFF_*, $_OPTS_X_*, and $_OPTS_MAN_*.
-	- $_OPTS_MANOPT_*: new variables for the parsing of $MANOPT.
-	- Correct $_OPTS_CMDLINE_*.
-	- Remove some unused $_OPTS_*.
-	- `--iconic': new option from `-iconic' of the X Window toolkit.
-	- Correct `--rv' to an option without argument.
-	- Minor fixes of other  X Window toolkit options.
-
-
-	******* Other fixes
-
-	* groffer.sh:
-	- is_prog(): allow 0 arguments.
-	- is_not_writable(): new function.
-	- is_*(): fix trailing return codes.
-        - Replace most `test' calls by is_*() functions.
-	- man_setup(): due to bugs in `manpath', prefer
-	manpath_set_from_path() for the determination of the man page path.
-	- man_search_section(): correction of some `for' loops.
-	- Remove export of external non-groffer variables.
-
-
-	******* Documentation
-
-	* groffer.man:
-	- Reorder the option details according to the option origin as
-	groffer, groff, X, and man options.
-	- Add the programming changes information mentioned above.
-	- Support man pages with a dot in their name
-
-	* README_SH: new file
-	Move large parts of the documentation in `groffer.sh' into this
-	file.
-
-	* groffer.sh: usage():
-	- Change the output for `--help' to standard output.
-	- Restructure the information for this help output.
-
-
-	******* Removement of the author's email address
-
-	Because of the extreme spam attacks, the author removed all
-	occurencies of his email address in every file of the groffer
-	source.
-
-2003-01-22  Bernd Warken
-	________________________________________________________________
-	* release of groffer 0.9.4
-
-	* groffer.sh: corrections for some restrictive shells
-	- Possible exit codes in actual `ash' are between 0 and 63.  To
-	handle even deeper restrictions, use 7 as maximal code instead
-	of 255 as replacement for error -1.
-	- Remove variables $_BAD2 and $_BAD3.
-	- Replace `trap' argument `EXIT' by 0 and write new fuctions
-	`trap_clean' and `trap_set' to handle the restrictions of `trap'
-	for some shells.
-	- Correct wrong $MANPATH to $_MAN_PATH in function
-	`man_do_filespec'.
-	- Test existence of directory before deleting it in the
-	`clean_up' definitions.

-	* release of groffer 0.9.3
-
-	* groffer.sh: new temporary subdirectory
-	- Generate temporary subdirectory for storing temporary files
-	with better names in future groffer versions (name:
-	"groffer$$" in usual temporary directory).
-	- Use `umask 000' for temporary files to allow cleaning up
-	for everyone after a system break.
-	- Change both clean_up() functions (for normal shell and
-	for main_display() subshell) to handle the new subdirectory.
-	- clean_up_secondary() and $_TMP_PREFIX are unnecessary now, so
-	they were removed.
-
-	* Makefile.sub: `sed' commands for "groffer:"
-	- Remove "@g@" entry (not used in "groffer.sh").
-	- Add global replace for "@BINDIR@" and "@VERSION@" for future
-	usage.

-	- Remove the 'sed' complaints.
-
-2002-07-15  Bernd Warken
-
-	* groffer.sh: replace `sed' interface by direct `sed'
-	- This improves the performance of the shell programming parts
-	  and shortens the groffer script by about 5%.
-	- Remove functions: string_del_append(), string_del_leading(),
-	  string_del_trailing(), string_flatten(), string_get_before(),
-	  string_get_leading(), string_replace_all(), string_sed_s(),

-	- New option `--shell': stop execution and rerun groffer under
-	  the shell specified in the argument of `--shell'.
-	- If no shell was specified at run-time, `ash' is tried first;
-	  if `ash' is not available continue with the shell with which
-	  groffer was called from the command line, or with the shell
-	  name in the first line of the script, actually `/bin/sh'.
-
-2002-07-12  Bernd Warken
-	________________________________________________________________
-	* fixes for groffer 0.9.0
-
-	* groffer.sh: enhance version information
-	`groffer -v|--version' now print:
-	- groffer's version number and date
-	- the string `is part of '
-	- groff's version information (version number and copyright),
-	  but not groff's `called subprograms' information.
-
-	* groffer.sh: minor fixes
-	- Fix the argument parser to process argument `-' correctly.
-	- Some display programs have trouble with empty input; feed a
-	  line consisting of a single space character in this case for
-	  all display modes (not for source or groff modes).
-

-	________________________________________________________________
-	* release of groffer 0.9.0
-
-	* groffer.sh: new mode `pdf'
-	- PDF (Portable Document Format):
-	  -> Transform groff `ps' output into pdf using `gs'.
-	  -> Pro: PDF viewers provide text searching (!).
-	  -> Con: the transformation is quite slow.
-	  -> Not suitable as an auto mode.
-	- New options `--pdf', `--pdf-viewer', `--mode pdf'.
-	- Standard pdf viewers `xpdf' and `acroread'.
-	- For `xpdf', choose zoom `z 3' for 100 dpi, `z 2' for 75 dpi.
-
-	* groffer.sh: support bzip2 decompression
-	- add test for `bzip2' with necessary options

-	- Document the configuration files in new section `FILES'.
-	- Redesign section `EXAMPLES'.
-	- Remove documentation for `-W'.
-
-	* groffer.sh: new debugging features
-	- Disabled by default; enabled by environment variables.
-	- Add landmark() to catch typos with quotes.
-	- Add a function call stack for suitable functions; implemented
-	  as within the argument checker func_check().
-	- This implies the need to provide `return' with some clean-up
-	  facility; implemented as `eval "$_return_..."'.
-	- Add option `--debug' to enable debugging at run-time.
-	- Actually, the groffer script uses only shell builtins found
-	  in `ash' (a subset of POSIX) and POSIX `sed' as the only
-	  external shell utility.
-
-	* groffer.sh: customization of viewers
-	- In `groff' mode, the groffer viewing facilities are disabled.
-	- The postprocessor option `-P' costumizes the viewer only in
-	  some situations in the `groff' mode, so a new infrastructure
-	  for viewer customization is necessary.
-	- Allow to specify arguments to the viewer programs specified
-	  in `--*-viewer()'.
-	- Implement some of the essential X Toolkit resource options in
-	  groffer, but with use a leading double minus.
-	  -> `--bd': set border color.
-	  -> `--bg', `--background': set background color.
-	  -> `--bw': set border width.
-	  -> `--display': set X display.
-	  -> `--geometry': set size and position of viewer window.
-	  -> `--fg', `--foreground': set foreground color.

-	  -> `--resolution': set X resolution in dpi.
-	  -> `--title': set viewer window title.
-	  -> `--xrm': set X resource.
-	- Remove misnamed option `--xrdb'.
-
-	* groffer.sh: new mode structure
-	- New Postcript mode `ps' (`--ps'):
-	  -> default viewers: gv,ghostview,gs_x11,gs;
-	  -> `--ps-viewer' sets the Postscript viewer.
-	- New mode `www' (`--www') for displaying in a web browser:
-	  -> default browsers: mozilla,netscape,opera,amaya,arena;
-	  -> `--www-viewer' sets the web browser.
-	- New dvi mode (`--dvi'); default viewer `xdvi':
-	  -> default viewers: xdvi,dvilx;
-	  -> `--dvi-viewer' sets the dvi viewer.
-	- New mode `auto':
-	  -> active if no other mode is given or by new option `--auto';
-	  -> selects from a sequence of modes that are tested until one
-	    of them succeeds.
-	  -> the default mode sequence is actually `ps', `x', `tty'.
-	  -> `--default-modes' sets this mode sequence as a comma
-	     separated string of program names, optionally each one
-	     with arguments).
-	- New mode `groff':
-	  -> process input like groff, ignore viewing options.
-	  -> activated by new option `--groff'.
-	  -> automatically active with one of `-V', `-X', `-Z'.
-	- Revise `tty' mode:
-	  -> allow several text devices.
-	  ->
-	- Reorganize the mode management:
-	  -> new mode setting option `--mode'.
-	  -> logically separate source, groff, and display modes.
-	  -> intermediate output mode is now part of mode groff; remove
-	     any special features around `-Z'.
-	- Update usage() to reflect the new option structure.
-
-	* groffer.sh: add configuration files
-	- `/etc/groff/groffer.conf' system-wide configuration.
-	- `${HOME}/.groff/groffer.conf' user configuration.
-	- The configuration file are shell scripts for now; later
-	  implementations can identify this from the `#! /bin/sh' line.
-
-	* groffer.sh: new data structure `list':
-	- Implement a `list' data structure as a string consisting of
-	  single-quoted elements, separated by a space character;
-	  embedded single-quotes are escaped.
-
-	* groffer.sh: new option parser based on `list':
-	- Write new option parser based on `list', compatible to both
-	  POSIX getopts() and GNU getopt().
-	- Long options are now available on GNU and non-GNU systems.
-	- Get rid of POSIX getopts() and GNU getopt().
-	- the `-W--longopt' construct is now obsolete; remove it.
-	- add test/function for `unset'.
-	- Option strings are now implemented as `list's in order to
-	  allow unusual characters in options.
-	- Parse $MANOPT first; translate essential arguments into
-	  groffer options.
-
-	* groffer.man:
-	- determine prompt length for `.Shell_cmd'* dynamically.
-	- naming scheme for static strings and registers changed to
-	  `namespace:macro.variable'.

-	________________________________________________________________
-	* release of groffer 0.7
-
-	* groffer.sh: remove incompatibilities with the `ash' shell:
-	- do not use `!command':
-          -> use `else'
-	  -> write `_not_' equivalents for some functions
-	- do not use `[^]' in `case':
-	  ->  restructure some functions.
-	- only single-character names for loop variables:
-	  -> spoils the paradigm of leading `_' for local variables.
-	- spurious trouble with `for i in ${var}':
-	  -> use `eval set -- ${var}' and `for i in "$@"'
-	- do not change or use $IFS:
-	  -> define new functions string_split() and `path_split()'.
-	  -> result must be processed by `eval set --'.
-	  -> solve conflicts with existing positional parameters.
-	- trouble with exporting external `$GROFF_*' variables:
-	  -> hope that they were exported in the calling shell.
-	- not smart about additional blanks:
-	  -> remove unnecessary white space.
-
-	* groffer.sh: improve run-time speed:
-	- `ash' more than doubles the speed of `bash'.
-	- speed-up `man_setup()'.
-
-
-2002-05-30  Werner Lemberg  <wl@gnu.org>

-	This is almost a complete rewrite since groffer 0.5 .
-	________________________________________________________________
-	* Documentation
-
-	* groffer.man:
-   	- Apply the changes done in www.tmac (.URL and .MTO)
-	- Replace \fP by \f[].
-	- Redesign and rewrite most macros.
-	- Include the documentation for the new features.
-	- Greatly enlarge section ENVIRONMENT
-	- Add examples.
-
-	* TODO:
-	- Start a TODO file with several sections.
-
-	* ChangeLog:
-	Due to the many changes, shorten and rearrange the entries
-	since groffer 0.5 .
-	________________________________________________________________
-	* Shell compatibility
-
-	* groffer.sh:
-	- Due to possible conflicts in old BSD versions, `[]' was
-	  replaced by `test'; the `test' options `-a' and `-o' were
-	  replaced by multiple calls of `test'.
-	- Write interface to the `sed' command `s' to become
-	  independent of the delimiter character.  Rewrite all text
-	  manipulating function to use this new scheme.  The new
-	  functions are named `string_*'.
-	- `tr' is not needed any longer, replaced by `sed'.
-	- `grep' is not needed any longer, mostly replaced by `case'.
-	- Revision of test for `getopt'.
-	- Remove `set -a'; explicitly export variables.
-	- The only external programs used are POSIX `sed' and the
-	  fallback to `apropos'.  All other program calls were
-	  replaced by shell builtins and functions.
-
-	________________________________________________________________
-	* Cosmetics
-
-	* groffer.sh:
-	- Implement a prefix based naming scheme for local variables
-	  and functions (OOP-like).
-	- Introduce variables for white space (better readability with
-	  $IFS).
-	- Store the names of the processed filespecs into a variable
-	  instead of a temporary file.
-	- Error-prone shell constructions were replaced by functions
-	  with a simple interface.
-	- To avoid too long pipes, replace supercat() by do_fileargs();
-	  every input file is handled independently.
-
-	________________________________________________________________
-	* New features:
-	- Add support for more X devices (e.g. X75-12 and X100-12).
-	- Add long option `--intermediate_output' to `-Z'.
-	- Make the options for mode selection clobber each other.
-	- Add option `--mode' with an argument having the following
-	  values:
-	  `X': force displaying in X, same as options `-X';
-	  `tty': display with a pager on text terminal; same as `--tty';
-	  `source', `default', `auto', etc.
-	- Make the handling of the X mode like in groff (e.g. -X -Tps).
-	- Make resolution for gxditview behave like groff (default
-	  75 dpi).
-	- Add environment variable $GROFFER_OPT to preset groffer
-	  options.
-
-	________________________________________________________________
-	* implement most of the functionality of GNU `man'.
-
-	- Add all `man' long options to groffer.
-	- Add all `man' environment variables.
-	- Parse and use content of `$MANOPT'.
-	- The precedence of the options and environment variables
-	  is regulated like in GNU `man'.
-	- Force the option `--manpath' to have a colon-separated
-	  argument like GNU `man'.
-	- Support `man section name' calling convention.
-	- Remove all dependencies on `man -w'.
-
-	* groffer.sh:
-	- Add the new features above.
-	- Rewrite the search algorithm for man pages.
-	- Remove searching with `man -w' (problems with space
-	  characters in file names).
-	- Fix and complement usage().
-	- The filespec parsers gets a function of its own do_manpage().
-
-

-README
-
-The `groffer' program is the easiest way to read documents written in
-some `roff' language, such as the `man pages', the manual pages in
-many operating systems.
-
-
-Input
-
-Input comes from either standard input or command line parameters that
-represent names of exisiting roff files or standardized specifications
-for searching man pages.  All of these can be compressed in a format
-that is decompressible by `gzip', including `.gz', `bz2', and `.Z'.
-
-`groffer' has many built-in `man' functionalities to find and read the
-manual pages on UNIX and similar operating systems.  It accepts the
-information from an installed `man' program, but tries to find a man
-path by itself.
-
-`groffer' bundles all filespec parameters into a single output file in
-the same way as `groff'.  The disadvantage of this is that all file
-name arguments must use the same groff language.  To change this, the
-option parsing must be revised for large parts.  It seems that this
-would create incompatibilities, so the actual option strategy is kept.
-
-
-Output
-
-All input is first sent to `grog' to determine the necessary `groff'
-options and then to `groff'.  So no special `groff' arguments must be
-given.  But all `groff' options can be specified when this seems to be
-appropriate.
-
-The following displaying modes for the output are available:
-- Display formatted input with
--- the X `roff' viewer `gxditview',
--- a Postcript viewer,
--- a PDF viewer,
--- a DVI viewer,
--- a web browser,
--- a pager in a text terminal (tty).
-- Generate `groff' output on stdout without a viewer.
-- Generate the `groff intermediate output' on standard output without
-  postprocessing.
-- Output the source code without any `groff' processing.
-- There are some information outputs without `groff' processing, such
-  as by option `-V' and the `man' like `whatis' and `apropos'
-  outputs.
-
-By default, the program tries to display with `gxditview' as graphical
-device in X; on non-X text terminals, the `tty' text mode with a pager
-is tried by default.
-
-
-Compatibility
-
-`groffer' consists of two shell scripts.  It should run on any POSIX
-or Bourne style shell that supports shell functions.  See file
-`README_SH' for more information.
-
-
-Mailing lists
-
-For reporting bugs of `groffer', groff's free mailing list
-<bug-groff@gnu.org> can be used.
-
-For a general discussion, the mailing list <groff@gnu.org> is more
-useful, but one has to subscribe to this list at
-http://lists.gnu.org/mailman/listinfo/groff.
-
-See the `README' file in the top directory of the `groff' source
-package for more details on these mailing lists.

-Additional description for the shell version of `groffer'
-
-
-Scripts
-
-The shell version of `groffer' contains two files, `groffer.sh' and
-`groffer2.sh'.
-
-`groffer.sh' is a short introductory script without any functions.  I
-can be run with a very poor Bourne shell.  It just contains some basic
-variables, the reading of the configuration files, and the
-determination of the shell for `groffer2.sh'.  This script is
-transformed by `make' into `groffer' which will be installed into
-@bindir@, which is usually /usr/local/bin.
-
-`groffer2.sh' is a long main script with all functions; it is called
-by `groffer.sh' (`groffer' after installation).  It is installed
-unchanged into @libdir@/groff/groffer, which is usually
-/usr/local/lib/groff/groffer.  This script can be called with a
-different shell, using the `groffer' option `--shell'.
-
-
-Options
-
-The `groffer' script provides its own option parser.  It is compatible
-to the usual GNU style command line This includes long option names
-with two signs such as `--option', clusters of short options, the
-mixing of options and non-option file names, the option `--' to close
-the option handling, and it is possible to abbreviate the long option
-names.
-
-The flexible mixing of options and file names in GNU style is always
-possible, even if the environment variable `$POSIXLY_CORRECT' is set
-to a non-empty value.  This disables the rather wicked POSIX behavior
-to terminate option parsing when the first non-option command line
-argument is found.
-
-
-Error Handling
-
-Error handling and exit behavior is complicated by the fact that
-`exit' can only escape from the current shell; trouble occurs in
-subshells.  This was solved by sending kill signals, see $_PROCESS_ID
-and error().
-
-
-Function Definitions in `groffer2.sh'
-
-Each funtion in groffer2.sh has a description that starts with the
-function name and symbols for its arguments in paranthesis `()'.  Each
-`<>' construction gives an argument name that just gives a hint on
-what the argument is meant to be; these argument names are otherwise
-irrelevant.  The `>' sign can be followed by another character that
-shows how many of these arguments are possible.
-
-<arg>      exactly 1 of this argument
-<arg>?     0 or 1 of these arguments
-<arg>*     arbitrarily many such arguments, incl. none
-<arg>+     one or more such arguments
-<arg>...   one or more such arguments
-[...]      optional arguments
-
-A function that starts with an underscore `_' is an internal function
-for some other function.  The internal functions are defined just
-after their corresponding function.
-
-
-External Environment Variables
-
-The groffer.sh script uses the following external system variables.
-It is supposed that these variables are already exported outside of
-groffer.sh; otherwise they do not have a value within the script.
-
-external system environment variables that are explicitly used
-$DISPLAY:		Presets the X display.
-$LANG:			For language specific man pages.
-$LC_ALL:		For language specific man pages.
-$LC_MESSAGES:		For language specific man pages.
-$PAGER:			Paging program for tty mode.
-$PATH:			Path for the programs called (`:' separated list).
-
-groffer native environment variables
-$GROFFER_OPT		preset options for groffer.
-
-all groff environment variables are used, see groff(1)
-$GROFF_BIN_PATH:	Path for all groff programs.
-$GROFF_COMMAND_PREFIX:	'' (normally) or 'g' (several troffs).
-$GROFF_FONT_PATH:	Path to non-default groff fonts.
-$GROFF_TMAC_PATH:	Path to non-default groff macro files.
-$GROFF_TMPDIR:		Directory for groff temporary files.
-$GROFF_TYPESETTER:	Preset default device.
-
-all GNU man environment variables are used, see man(1).
-$MANOPT:		Preset options for man pages.
-$MANPATH:		Search path for man pages (: list).
-$MANROFFSEQ:		Ignored because of grog guessing.
-$MANSECT:		Search man pages only in sections (:).
-$SYSTEM:		Man pages for different OS's (, list).
-
-
-Object-oriented Functions
-
-The groffer script provides an object-oriented construction (OOP).  In
-object-oriented terminology, a type of object is called a `class'; a
-function that handles objects from a class is named `method'.
-
-In the groffer script, the object is a variable name whose content is
-the object's data.  Methods are functions that have an object as first
-argument.
-
-The basic functions for object handling are obj_*().
-
-The class `list' represents an array structure, see list_*().
-
-
-Shell Compatibility
-
-The `groffer' shell scripts are compatible to both the GNU and the
-POSIX shell and utilities.  Care was taken to restrict the programming
-technics used here in order to achieve POSIX compatibility as far back
-as POSIX P1003.2 Draft 11.2 of September 1991.  This draft is
-available at http://www.funet.fi/pub/doc/posix/p1003.2/d11.2 in the
-internet.
-
-The POSIX draft does not include `local' variables for functions.  So
-this concept was replaced by global variables with a prefix that
-differs for each function.  The prefix is chosen from the function
-name.  These quasi-local variables are unset before each return of the
-function.
-
-The `groffer' scripts were tested under the shells `ash', `bash',
-`bash-minimal', `dash', 'ksh', `mksh', `pdksh', 'posh', and `zsh'
-without problems in Linux Debian.  A shell can be tested by the
-`groffer' option `--shell', but that will run only with groffer2.sh.
-To start it directly from the beginning under this shell the following
-command can be used.
-
-  <shell-name> groffer.sh --shell=<shell-name> <argument>...
-
-
-Some shells are not fully POSIX compatible.  For them the following
-restrictions were done.  For more information look at the
-documentation `Portable shells' in the `info' page of `autoconf'
-(look-up in Emacs-Help-Manuals_Info).
-
-- The command parts `then', `else', and `do' must be written each on a
-  line of their own.
-
-- Replace `for i in "$@"' by `for i' and remove internal `;' (kah).
-
-- Replace `set -- ...' by `set x ...; shift'.  After the first
-  non-option argument, all arguments including those starting with `-'
-  are accepted as non-option.  For variables or `$()' constructs with
-  line-breaks, use `eval set' without quotes.  That transforms a
-  line-break within a variable to a space.
-
-- The name of the variable in `for' is chosen as a single character
-  (old ash).  The content of such variables is not safe because it can
-  also occur in other functions.  So it is often stored in an
-  additional quasi-local variable.
-
-- `echo' is not portable on options; some `echo' commands have many
-  options, others have none.  So `echo -n' cannot be used, such that
-  the output of each function has complete lines.  There are two
-  methods to avoid having `-' as the first character of any argument.
-  Either a character such as `x' can be prepended to the argument;
-  this must later on be removed by `sed'.  Otherwise, `echo' can be
-  replaced by `cat <<EOF'.
-
-- `ls' has problems.  Old UNIX systems echoed the error message to
-  standard output.  So handle the output with `sed'.  If the output
-  contains `not found' map it to an empty string.
-
-- As `test -e' is not available in Solaris 2.5 replace it by
-  `test -f || test -d'.
-
-- As `unset' is not supported by all shells replace it by `eval
-  ${_UNSET}' where this variable is `unset' if it exists and `:'
-  otherwise.
-
-- Some shells have problems with options in `eval'.  So quoting must
-  be done right to hide the options from `eval'.
-
-- In backquote calls `` avoid the backquote ` in comments.
-
-- Replace `true' by `:', `false' isn't used.
-
-- Do not redefine builtins as functions (ash).
-
-- Avoid `[^...]' in `case' patterns (ash).
-
-- `trap' does not allow error code 127.
-
-The scripts call the following commands with all options used:
-.
-:
-apropos
-break
-bzip2 -c -d -t
-cat
-catz
-cd
-continue
-echo
-eval
-expr
-grep
-groff -v
-grog -T -X -Z
-gs -c -d -f -q -s
-gzip -c -d -f
-less -r -R
-ls
-man -k --apropos
-mkdir
-mv
-pwd
-return
-rm -f -r
-rmdir
-sed -e -n
-set -e
-sh -c
-shift
-test -c -d -f -r -s -w -x
-trap
-umask
-unset
-
-
-Bugs
-
-If the `groffer' run is interrupted by Crtl-C the clean up is not done
-by all shells.  The `trap' commands work for the shells `bash',
-`bash-minimal', and 'ksh'; they do not work for `ash', `dash',
-`pdksh', `posh', and `zsh'.

-TODO file for `groffer'
-
-File position: <groff-source>/contrib/groffer/TODO
-
-
-####### TODO
-
-Revision:
-
-Optimization:
-- Optimize `man' path determination in manpath_add_lang_sys() for speed
-  by building-up the `man' path only by and by as far as necessary
-  (not trivial).
-- To increase the running speed write part of the `groffer' shell
-  script in C/C++.
-
-Features of external programs:
-- Revise option handling of `grog'.
-
-Documentation:
-- Improve the documentation of the search algorithm for `man' pages in
-  both the `groffer' scripts and the `man' page `groffer.man'.
-- In `groffer.man', add more documentation for parts that were taken
-  over from GNU `man'.
-- The documentation in the headers for some function definitions in
-  `groffer2.sh' needs to be updated.

-.SH DESCRIPTION
-.\" --------------------------------------------------------------------
-.
-The
-.B \%groffer
-program is the easiest way to use
-.BR \%groff (@MAN1EXT@).
-It can display arbitrary documents written in the
-.I \%groff
-language, see
-.BR \%groff (@MAN7EXT@),
-or other
-.I \%roff
-languages, see
-.BR \%roff (@MAN7EXT@),
-that are compatible to the original
-.I \%troff
-language.
-.
-The
-.B \%groffer
-program also includes many of the features for finding and displaying
-the \%\f[CR]Unix\f[] manual pages
-.nh
-.RI ( man\~pages ),
-.hy
-such that it can be used as a replacement for a
-.BR \%man (1)
-program.
-.
-Moreover, compressed files that can be handled by
-.BR \%gzip (1)
-or
-.BR \%bzip2 (1)
-are decompressed on-the-fly.
-.
-.
-.P
-The normal usage is quite simple by supplying a file name or name of a
-.I \%man\~page
-without further options.
-.
-But the option handling has many possibilities for creating special
-behaviors.
-.
-This can be done either in configuration files, with the shell
-environment variable
-.BR \%$GROFFER_OPT ,
-or on the command line.
-.
-.
-.P
-The output can be generated and viewed in several different ways
-available for
-.IR \%groff .
-.
-This includes the
-.I \%groff
-native \%\f[CR]X\~Window\f[] viewer
-.BR \%gxditview (@MAN1EXT@),
-each
-.IR \%Postcript ,
-.IR \%pdf ,
-or
-.I \%dvi
-display program, a web browser by generating
-.I \%html
-in
-.IR \%www\~mode ,
-or several
-.I \%text\~modes
-in text terminals.
-.
-.
-.P
-Most of the options that must be named when running
-.B \%groff
-directly are determined automatically for
-.BR \%groffer ,
-due to the internal usage of the
-.BR \%grog (@MAN1EXT@)
-program.
-.
-But all parts can also be controlled manually by arguments.
-.
-.
-.P
-Several file names can be specified on the command line arguments.
-.
-They are transformed into a single document in the normal way of
-.BR \%groff .
-.
-.
-.P
-Option handling is done in \f[CR]GNU\f[] style.
-.
-Options and file names can be mixed freely.
-.
-The option
-.RB ` \-\- '
-closes the option handling, all following arguments are treated as
-file names.
-.
-Long options can be abbreviated.

-.SH "OPTION DETAILS"
-.\" --------------------------------------------------------------------
-.
-The
-.B \%groffer
-program can usually be run with very few options.
-.
-But for special purposes, it supports many options.
-.
-These can be classified in 5 option classes.
-.
-.
-.P
-All short options of
-.B \%groffer
-are compatible with the short options of
-.BR \%groff (@MAN1EXT@).
-.
-All long options of
-.B \%groffer
-are compatible with the long options of
-.BR \%man (1).
-.
-.
-.\" --------------------------------------------------------------------
-.SS "groffer breaking Options"
-.\" --------------------------------------------------------------------
-.
-As soon as one of these options is found on the command line it is
-executed, printed to standard output, and the running
-.B \%groffer
-is terminated thereafter.
-.
-All other arguments are ignored.
-.
-.
-.Opt_def - h -- help
-Print a helping information with a short explanation of option sto
-standard output.
-.
-.
-.Opt_def - v -- version
-Print version information to standard output.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "groffer Mode Options"
-.\" --------------------------------------------------------------------
-.
-The display mode and the viewer programs are determined by these
-options.
-.
-If none of these mode and viewer options is specified
-.B \%groffer
-tries to find a suitable display mode automatically.
-.
-The default modes are
-.I mode x
-with
-.B gxditview
-in \%\f[CR]X\~Window\f[] and
-.I mode tty
-with device
-.I latin1
-under
-.B less
-on a terminal.
-.
-.
-.P
-There are two kinds of options for viewers.
-.Opt_long \fImode\fP-viewer
-chooses the normal viewer programs that run on their own in
-\%\f[CR]X\~Window\f[], while
-.Opt_long \fImode\fP-viewer-tty
-chooses programs that run on the terminal (on tty).
-.
-Most graphical viewers are programs running in \%\f[CR]X\~Window\f[],
-so there aren't many opportunities to call the tty viewers.
-.
-But they give the chance to view the output source; for example,
-.Opt_long ps\-viewer\-tty=less
-shows the content of the
-.I Postscript
-output with the pager
-.BR less .
-.
-.
-.P
-The \%\f[CR]X\~Window\f[] viewers are not critical, you can use both
-.Opt_long *\-viewer
-and
-.Opt_long *\-viewer\-tty
-for them; with
-.Opt_long *\-viewer\-tty
-the viewer program will not become independently, it just stays
-coupled with
-.BR groffer .
-But the program will not run if you specify a terminal program with
-.Opt_long *\-viewer
-because this viewer will stay in background without a chance to reach
-it.
-.
-So you really need
-.Opt_long *\-viewer\-tty
-for viewers that run on tty.
-.
-.
-.Opt_def -- auto
-Equivalent to
-.Opt_long_arg mode auto .
-.
-.
-.Opt_def -- default
-Reset all configuration from previously processed command line options
-to the default values.
-.
-This is useful to wipe out all former options of the configuration, in
-.Env_var $GROFFER_OPT ,
-and restart option processing using only the rest of the command line.
-.
-.
-.Opt_def -- default\-modes mode1,mode2,\*[Ellipsis]
-Set the sequence of modes for
-.I \%auto\~mode
-to the comma separated list given in the argument.
-.
-See
-.Opt_long mode
-for details on modes.  Display in the default manner; actually, this
-means to try the modes
-.IR x ,
-.IR ps ,
-and
-.I \%tty
-in this sequence.
-.
-.
-.
-.Opt_def -- dvi
-Equivalent to
-.Opt_long_arg mode \%dvi .
-.
-.
-.Opt_def -- dvi\-viewer prog
-Choose an \%\f[CR]X\~Window\f[] viewer program for
-.IR \%dvi\~mode .
-.

-Known \%\f[CR]X\~Window\f[]
-.I \%dvi
-viewers include
-.BR \%xdvi (1)
-and
-.BR \%dvilx (1)
-.
-In each case, arguments can be provided additionally.
-.
-.
-.Opt_def -- dvi\-viewer\-tty prog
-Choose a program running on the terminal for viewing the output of
-.IR \%dvi\~mode .
-.
-This can be a file name or a program to be searched in

-The following mode values are recognized:
-.
-.RS
-.
-.TP
-.Header_CB auto
-Select the automatic determination of the display mode.

-viewing features.
-.
-.
-.TP
-.Header_CB html
-Translate the input into html format and display the result in a web
-browser program.

-or the
-.BR \%acroread (1)
-program.
-.
-PDF has a big advantage because the text is displayed graphically and
-is searchable as well.

-But the standard \%\f[CR]X\~Window\f[] tool
-.BR \%xditview (1)
-can also be chosen with the option
-.Opt_long x\-viewer .
-The default resolution is
-.BR 75\~dpi ,
-but
-.B 100\~dpi
-are also possible.
-.
-The default
-.I groff
-device
-for the resolution of
-.B 75\~dpi
-is
-.BR X75\-12 ,
-for
-.B 100\~dpi
-it is

-temporary directory and the shell name for
-.File_name groffer2.sh
-are printed, the parameters are printed at several steps of
-development, and a function stack is output with function
-\f[CR]error_user()\f[] as well.

-.
-.Opt_def -- print=text
-Just print the argument to standard error.
-.
-This is good for parameter check.
-.
-.
-.Opt_def -- shell "shell_program"
-Specify the shell under which the
-.File_name \%groffer2.sh

-.
-The following of
-.B \%groff
-options have either an additional special meaning within
-.B \%groffer
-or make sense for normal usage.
-.
-.
-.P
-Because of the special outputting behavior of the
-.B \%groff
-option
-.Opt_short Z
-.B \%groffer
-was designed to be switched into
-.I \%groff\~mode ;
-the
-.I \%groffer

-options do not switch the mode, but allow to customize the formatting
-process.
-.
-.
-.Opt_def - a
-This generates an ascii approximation of output in the
-.IR \%text\~modes .
-.
-That could be important when the text pager has problems with control
-sequences in

-.I \%opt_or_arg
-as an option or option argument to the actual
-.B \%groff
-postprocessor.
-.
-.
-.Opt_def - T -- device devname
-.
-This option determines
-.BR \%groff 's
-output device.
-.
-The most important devices are the text output devices for referring
-to the different character sets, such as
-.BR \%ascii ,
-.BR \%utf8 ,
-.BR \%latin1 ,
-and others.
-.
-Each of these arguments switches
-.B \%groffer
-into a
-.I \%text\~mode
-using this device, to
-.I \%mode\~tty
-if the actual mode is not a
-.IR \%text\~mode .

-.
-A
-.I \%filespec
-parameter is an argument that is not an option or option argument.
-.
-It means an input source.
-.
-In
-.BR \%groffer ,
-.I \%filespec
-parameters are a file name or a template for searching
-.IR \%man\~pages .
-.
-These input sources are collected and composed into a single output
-file such as
-.B \%groff
-does.
-.
-.
-.P
-The strange \%\f[CR]POSIX\f[] behavior to regard all arguments behind
-the first non-option argument as
-.I \%filespec
-arguments is ignored.
-.
-The \f[CR]GNU\f[] behavior to recognize options even when mixed with
-.I \%filespec
-arguments is used througout.
-.
-But, as usual, the double minus argument
-.Opt_long
-ends the option handling and interprets all following arguments as
-.I \%filespec
-arguments; so the \%\f[CR]POSIX\f[] behavior can be easily adopted.
-.
-.
-.P
-For the following, it is necessary to know that on each system the
-.I \%man\~pages
-are sorted according to their content into several sections.
-.
-The
-.I classical man sections
-have a single-character name, either a digit from
-.B 1
-to
-.B 9
-or one of the characters
-.B n
-or
-.BR o .
-.
-In the following, a stand-alone character
-.I s
-stands for a
-.IR "classical man section" .
-The internal precedence of
-.B \%man
-for searching
-.I \%man\~pages
-with the same name within several sections goes according to the
-classical single-character sequence.
-.
-On some systems, this single character can be extended by a following
-string.
-.
-But the special
-.B \%groffer
-.I \%man\~page
-facility is based on the classical single character sections.
-.
-.
-.P
-Each
-.I \%filespec
-parameter can have one of the following forms in decreasing sequence.
-.
-.
-.Topic
-No
-.I \%filespec
-parameters means that
-.B \%groffer
-waits for standard input.
-.
-The minus option
-.Opt_short ""
-stands for standard input, too; it can occur several times.
-.
-.
-.Topic
-Next a
-.I \%filespec
-is tested whether it is the path name of an existing file.
-.
-Otherwise it is assumed to be a searching pattern for a
-.IR \%man\~page .
-.
-.
-.Topic
-.BI \%man: name ( section )
-and
-.IB \%name ( section )
-search the \%man\~page
-.I \%name
-in \%man\~section\~\c
-.IR \%section ,
-where
-.I \%section
-can be any string, but it must exist in the
-.I \%man
-system.
-.
-.
-.Topic
-Next some patterns based on the
-.I classical man sections
-are checked.
-.
-.BI \%man: name . s
-and
-.IB \%name . s
-search for a \%man\~page
-.I \%name
-in \%man\~section
-.I s
-if
-.I s
-is a
-.I classical man section
-mentioned above.
-.
-Otherwise a
-.I \%man\~page
-named
-.IR \%name.s
-is searched in the lowest
-.B man\~section .
-.
-.
-.Topic
-Now
-.BI \%man: name
-searches for a
-.I \%man\~page
-in the lowest
-.I \%man\~section
-that has a document called
-.IR \%name .
-.
-.
-.Topic
-The pattern
-.I \%s\~name
-originates from a strange argument parsing of the
-.B man
-program.
-.
-If
-.I s
-is a
-.I classical man section
-interpret it as a search for a
-.I \%man\~page
-called
-.I \%name
-in man\~section
-.IR s ,
-otherwise interpret both
-.I s
-and
-.I \%name
-as two independent
-.I \%filespec
-arguments.
-.
-.
-.Topic
-We are left with the argument
-.I \%name
-which is not an existing file.
-.
-So this searches for the
-.I \%man\~page
-called
-.I \%name
-in the lowest
-.I \%man\~section
-that has a document for this name.
-.
-.
-.P
-Wildcards in
-.I \%filespec
-arguments are only accepted for
-.Opt_long apropos*
-and
-.Opt_long whatis ;
-for normal display, they are interpreted as characters.
-.
-.
-.P
-Several file name arguments can be supplied.
-.
-They are mixed by
-.B \%groff
-into a single document.
-.
-Note that the set of option arguments must fit to all of these file

-.
-The
-.B \%groffer
-program is a shell script that is run through
-.File_name /bin/sh ,
-which can be internally linked to programs like
-.BR \%bash (1).
-The corresponding system environment is automatically effective.
-.
-The following variables have a special meaning for
-.BR \%groffer .
-.
-.
-.TP
-.Env_var $DISPLAY
-If this variable is set this indicates that the \%\f[CR]X\~Window\f[]
-system is running.
-.
-Testing this variable decides on whether graphical or text output is
-generated.
-.
-This variable should not be changed by the user carelessly, but it can
-be used to start the graphical
-.B \%groffer
-on a remote \%\f[CR]X\~Window\f[] terminal.
-.
-For example, depending on your system,
-.B \%groffer
-can be started on the second monitor by the command
-.Shell_cmd DISPLAY=:0.1\~groffer\~ what.ever &
-.
-.
-.TP
-.Env_var $LC_ALL
-.TP+
-.Env_var $LC_MESSAGES
-.TP+
-.Env_var $LANG
-If one of these variables is set (in the above sequence), its content
-is interpreted as the locale, the language to be used, especially when
-retrieving
-\IR \%man\~pages .
-.
-A locale name is typically of the form
-.nh
-.IR language [\c
-.B _\c
-.IR territory [\c
-.B .\c
-.IR codeset [\c
-.B @\c
-.IR modifier ]]],
-.hy
-where
-.I \%language
-is an ISO 639 language code,
-.I \%territory
-is an ISO 3166 country code, and
-.I \%codeset
-is a character set or encoding identifier like ISO-8859-1 or UTF-8;
-see
-.BR \%setlocale (3).
-.
-The locale values \f[CR]C\f[] and \%\f[CR]POSIX\f[]
-stand for the default, i.e. the
-.I \%man\~page
-directories without a language prefix.
-.
-This is the same behavior as when all 3\~variables are unset.

-.Env_var $PATH
-All programs within the

-support for all environment variables documented in
-.BR \%man (1)
-was added to
-.BR \%groffer ,
-but the meaning was slightly modified due to the different approach in
-.BR \%groffer ;
-but the user interface is the same.
-.
-The

-.TP
-.Env_var $EXTENSION
-Restrict the search for
-.I \%man\~pages
-to files having this extension.
-.
-This is overridden by option
-.Opt_long extension ;
-see there for details.
-.
-.
-.TP
-.Env_var $MANOPT
-This variable contains options as a preset for
-.BR \%man (1).
-As not all of these are relevant for
-.B \%groffer
-only the essential parts of its value are extracted.

-because the necessary preprocessors are determined automatically.
-.
-.
-.\" --------------------------------------------------------------------
-.SH "CONFIGURATION FILES"
-.\" --------------------------------------------------------------------
-.
-The
-.B \%groffer
-program can be preconfigured by two configuration files.
-.
-.
-.TP
-.File_name /etc/groff/groffer.conf
-System-wide configuration file for
-.BR \%groffer .
-.
-.
-.TP
-.File_name $HOME/.groff/groffer.conf
-User-specific configuration file for
-.BR \%groffer ,
-where
-.Env_var $HOME
-denotes the user's home directory.
-.
-This file is called after the system-wide configuration file to enable
-overriding by the user.
-.
-.
-.P
-The precedence of option delivery is given in the following.
-.
-The configuration file in
-.File_name /etc
-has the lowest precedence; it is overwritten by the configuration file
-in the home directory; both configuration files are overwritten by the
-environment variable
-.Env_var $GROFFER_OPT ;
-everything is overwritten by the command line.
-.
-.
-.P
-In the configuration files, arbitrary spaces are allowed at the
-beginning of each line, they are just ignored.
-.
-Apart from that, the lines of the configuration lines either start
-with a minus character, all other lines are interpreted as shell
-commands.
-.
-.
-.P
-The lines with the beginning minus are interpreted as
-.B groffer
-options.
-.
-This easily allows to set general
-.B \%groffer
-options that should be used with any call of
-.BR \%groffer .
-.
-Each line can represent a single short option, a short option cluster,
-or a long option with two minus signs, eventually with an argument.
-.
-The argument can be appended either after a space character or an
-equal sign
-.RB ` = '.
-The argument can be surrounded by quotes, but this is not necessary.
-.
-The options from these lines are collected and prepended to the
-existing value of
-.Env_var $GROFFER_OPT
-at the end of each configuration file.
-.
-.
-.P
-After the transformation of the minus lines, the configuration files
-have been transferred into a shell script that is called within
-.B \%groffer
-using the `\c
-.CB \.\~\c
-.IR \%filename '
-shell syntax.
-.
-.
-.P
-It makes sense to use these configuration files for the following
-tasks:
-.
-.Topic
-Preset command line options, such as choosing a
-.I \%mode
-or a viewer.
-.
-These are written into lines starting with a single or double minus
-sign, followed by the option name.
-.
-.Topic
-Preset environment variables recognized by
-.BR \%groffer ;
-but do not forget to export them.
-.
-.Topic
-You can also write a shell function for calling, for example a viewer
-program for some
-.IR \%mode .
-Such a function can be fed into a corresponding
-.Opt_long \f[I]mode\f[]\-viewer
-option.
-.
-.Topic
-Enter
-.Opt_long shell
-to specify a shell for the run of
-.File_name groffer2.sh .
-Some shells run much faster than the standard shell.
-.
-.
-.P
-As an example, consider the following configuration file in
-.File_name ~/.groff/groffer.conf ,
-say.
-.
-.P
-.ft CR
-.nh
-.nf
-# groffer configuration file
-#
-# groffer options that are used in each call of groffer
-\-\-shell=ksh
-\-\-foreground=DarkBlue

-  export DISPLAY='localhost:0.0'
-fi
-date >>~/mygroffer.log
-.fi
-.hy
-.ft
-.
-.
-.P
-The lines starting with
-.B #
-are command lines.
-.
-This configuration sets four
-.B \%groffer
-options (the lines starting with `\-') and runs two shell commands (the
-rest of the script).
-.
-This has the following effects:
-.
-.
-.Topic
-Use
-.B ksh
-as the shell to run the
-.B \%groffer
-script; if it works it should be faster than the usual
-.BR sh .
-.
-.
-.Topic
-Use a text color of
-.B \%DarkBlue
-in all viewers that support this, such as
-.BR \%gxditview .
-.
-.
-.Topic
-Use a resolution of
-.B 100\~dpi
-in all viewers that support this, such as
-.BR \%gxditview .
-.
-By this, the default device in
-.I x mode
-is set to
-.BR X100 .
-.
-.
-.Topic
-Force
-.BR \%gxditview (@MAN1EXT@)
-as the
-.I \%x-mode
-viewer using the geometry option for setting the width to
-.B 900\~dpi
-and the height to
-.BR 1200\~dpi .
-This geometry is suitable for a resolution of
-.BR 100\~dpi .
-.
-.
-.Topic
-If the environment variable
-.Env_var $DISPLAY
-is empty set it to
-.IR localhost:0.0 .
-.
-That allows to start
-.B \%groffer
-in the standard \%\f[CR]X\~Window\f[] display, even when the program
-is called from a text console.

-.
-The usage of
-.B \%groffer
-is very easy.
-.
-Usually, it is just called with a file name or
-.IR \%man\~page .
-.
-The following examples, however, show that
-.B \%groffer
-has much more fancy capabilities.
-.
-.
-.TP
-.Shell_cmd "groffer\~/usr/local/share/doc/groff/meintro.ms.gz"
-Decompress, format and display the compressed file
-.File_name meintro.ms.gz
-in the directory
-.File_name /usr/local/share/doc/groff ,
-using the standard viewer
-.B \%gxditview
-as graphical viewer when in \%\f[CR]X\~Window\f[], or the
-.BR \%less (1)
-pager program when not in \%\f[CR]X\~Window\f[].
-.
-.
-.TP
-.Shell_cmd "groffer\~groff"
-If the file
-.File_name \%./groff
-exists use it as input.
-.

-named
-.B \%groff
-in the smallest possible
-.IR \%man\~section ,
-being section 1 in this case.

-.I \%man\~section
-.BR 7 .
-This section search works only for a digit or a single character from
-a small set.
-.
-.
-.TP
-.Shell_cmd "groffer\~fb.modes"
-If the file
-.File_name ./fb.modes
-does not exist interpret this as a search for the
-.I \%man\~page
-of
-.BR fb.modes .
-As the extension
-.I \%modes
-is not a single character in classical section style the argument is
-not split to a search for
-.BR fb .
-.
-.
-.TP
-.Shell_cmd "groffer\~groff\~\[cq]troff(1)\[cq]\~man:roff"
-.
-The arguments that are not existing files are looked-up as the

-.\" --------------------------------------------------------------------
-.SH "COMPATIBILITY"
-.\" --------------------------------------------------------------------
-.
-The
-.B \%groffer
-program consists of two shell scripts.
-.
-.
-.P
-The starting script is the file
-.File_name \%groffer
-that is installed in a
-.File_name bin
-directory.
-.
-It is generated from the source file
-.File_name \%groffer.sh .
-.
-It is just a short starting script without any functions such that it
-can run on very poor shells.
-.
-.
-.P
-The main part of the
-.B \%groffer
-program is the file
-.File_name groffer2.sh
-that is installed in the
-.I groff
-library directory.
-.
-This script can be run under a different shell by using the
-.B \%groffer
-option
-.Opt_long shell .
-.
-.
-.P
-Both scripts are compatible with both
-\f[CR]GNU\f[] and \%\f[CR]POSIX\f[].
-.
-\%\f[CR]POSIX\f[] compatibility refers to
-\%\f[CR]IEEE\~P1003.2/D11.2\f[] of September 1991, a very early
-version of the \%\f[CR]POSIX\f[] standard that is still freely
-available in the internet at
-.URL http://\:www.funet.fi/\:pub/\:doc/\:posix/\:p1003.2/\:d11.2/\:all \
-"\%POSIX\~P1003.2\~draft\~11.2" .
-.
-.
-.P
-Only a restricted set of shell language elements and shell builtins is
-used to achieve even compatibility with some Bourne shells that are
-not fully \%\f[CR]POSIX\f[] compatible.
-.
-The
-.B \%groffer
-shell scripts were tested on many shells, including the following
-Bourne shells:
-.BR \%ash (1),
-.BR \%bash (1),
-.BR \%dash (1),
-.BR \%ksh (1),
-.BR \%pdksh (1),
-.BR \%posh (1),
-and
-.BR \%zsh (1).
-So it should work on most actual free and commercial operating
-systems.
-.
-.
-.P
-The shell for the run of
-.File_name groffer2.sh
-can be chosen by the option
-.Opt_long shell
-on the command line or the environment variable
-.Env_var $GROFF_OPT .
-If you want to add it to one of the
-.B \%groffer
-configuration files you must write a line starting with
-.Opt_long shell .
-.
-.
-.P
-The
-.B \%groffer
-program provides its own parser for command line arguments that is
-compatible to both \%\f[CR]POSIX\f[]
-.BR \%getopts (1)
-and \%\f[CR]GNU\f[]
-.BR \%getopt (1).
-It can handle option arguments and file names containing white space
-and a large set of special characters.
-.
-The following standard types of options are supported.
-.
-.
-.Topic
-The option consisiting of a single minus
-.Opt_short
-refers to standard input.
-.
-.
-.Topic
-A single minus followed by characters refers to a single character
-option or a combination thereof; for example, the
-.B \%groffer
-short option combination
-.Opt_short Qmfoo
-is equivalent to
-.Opt_short Q\~\-m\~foo .
-.
-.
-.Topic
-Long options are options with names longer than one character; they
-are always preceded by a double minus.
-.
-An option argument can either go to the next command line argument or
-be appended with an equal sign to the argument; for example,
-.Opt_alt -- long=arg
-is equivalent to
-.Opt_alt -- long\~arg .
-.
-.
-.Topic
-An argument of
-.Opt_--
-ends option parsing; all further command line arguments are
-interpreted as
-.I \%filespec
-parameters, i.e. file names or constructs for searching
-.IR \%man\~pages ).
-.
-.
-.Topic
-All command line arguments that are neither options nor option
-arguments are interpreted as
-.I \%filespec
-parameters and stored until option parsing has finished.
-.
-For example, the command line
-.Shell_cmd "groffer file1 -a -o arg file2"
-is equivalent to
-.Shell_cmd "groffer -a -o arg -- file1 file2"
-.
-.
-.P
-The free mixing of options and
-.I \%filespec
-parameters follows the GNU principle.
-.
-That does not fulfill the strange option behavior of \%\f[CR]POSIX\f[]
-that ends option processing as soon as the first non-option argument
-has been reached.
-.
-The end of option processing can be forced by the option
-.RB ` \-\- '
-anyway.

-	* Added number variable Hss
-	* Changed Hps1 and Hps2 to units

-
-	* version 1.30
-	* This is more like a beta-release, bugs might pop up. :-)
-	* last line in TOC was not correctly terminated (missing .br)
-	* changed the indentation for displays, it will now
-	  indent to the current indent, not the one at the definition
-	  of the display.
-	* Equation marks should now work better, indentation also.
-	* included these bug fixes from Larry Jones:
-	*   The documentation for the argument to .AS was incorrect for MT 4.
-	*   \*(EM should be a double-dash for nroff.
-	*   \nS is in points, not units.
-	*   If \nO isn't set, the default page offset should be .75i for nroff
-		and .963i for troff.
-	*   .S D should set the point size to \nS, not 10.
-	*   .S was setting the vertical spacing based on the old point size
-		instead of the new point size.
-	*   Got rid of a spurrious .br that prevented run-in headings from
-		working.
-	*   Reset the .SP counters in pg@header so that spacing on one page
-		won't affect spacing on subsequent pages.
-	*   Allow .AU and .AF with no arguments (real mm does, even though it
-		isn't documented).
-	*   Do .init@reset first thing to initialize the default environment.
-	*   For MT 4, the title should be 4 points larger than the default size,
-		not 12 point.
-	*   The cover environment needs to be initialized.
-	*   Printing the abstract on the first page needs to be controlled by
-		the .AS argument.
-	*   Heading eject should be suppressed if the heading immediately
-		follows the first page stuff (title, author, etc.).
-	*   support for table of contents numbering style (.nr Oc)
-	*   changes the troff empty line height from .25v to .5v
-	*   fixed section page numbering
-	*   fixed a really nasty bug in footnotes that could cause you
-		to lose the page footer completely if the very first
-		footnote on the page occurred at just the wrong place
-

-Beware!
-This may be old information. Trust only the source. :-)
-
-Implementation notes. (Or how to make your own national mm)
-
-Different commands:
-
-COVER [arg]
-MT [arg [addressee]]
-The arg is part of a filename in mm/*.MT or mm/*.cov.
-This file is read when the macro is executed. Therefore it must be
-put before any text output.
-In each file there are definitions of all extra macros needed for the
-cover sheet. MT files is only for compatibility reasons, and has several
-limits due to that it don't know when the cover starts, and cannot
-change sizes. Use COVER for new coversheet macros.
-
-But with MT it is possible to write all of the AT&T covers.
-An example can be found in mm/0.MT.
-
-When writing a new cover using COVER, have in mind that the cover
-should print the page with the COVEND macro. This macro
-should be defined by the new macrofile.
-
-Here is a part of ms.cov:
-> .\"-----------------
-> .de COVEND
-> .sp |4.2c
-> .cov@print-title
-> .cov@print-authors
-> .cov@print-firm
-> .cov@print-abstract
-> .cov@print-date
-This is important, since COVER disables the page header.
-> .pg@enable-top-trap
-Should begin with page one (normally).
-> .bp 1
-And enable the trap at the page footer.
-> .pg@enable-trap
-> ..

-This is mgm, a macro package for groff.
-
-It is supposed to be compatible with the DWB mm macros,
-and has several extensions.
-
-Send bug reports to jh@axis.com with a description of the problem
-and a sample of text which reproduces the error.
-
-Don't forget to mention the version of mgm (look in the beginning
-of m.tmac) and the version of groff.
-
-Any new ideas or improvements are welcome.
-
-Newest version is available here or at the groff CVS repository.
-ftp://ftp.axis.se/pub/groff/mm<something>.gz
-
-You can install mgm as a separate package without the configure in groff
-with the following command:
-
-make -f Makefile.sim install
-
-This README should be bigger :-)
-

-.TH GROFF_MM @MAN7EXT@ "@MDATE@" "Groff Version @VERSION@"
-.SH NAME
-groff_mm \- groff mm macros
-.SH SYNOPSIS
-.B groff
-.B \-m@TMAC_M_PREFIX@m
-[
-.IR options .\|.\|.
-]
-[
-.IR files .\|.\|.
-]
-.SH DESCRIPTION
-The groff mm macros are intended to be compatible with the DWB mm macros
-with the following limitations:
-.TP
-.B \(bu
-no Bell Labs localisms implemented.
-.TP
-.B \(bu
-the macros OK and PM are not implemented.
-.TP
-.B \(bu
-groff mm does not support cut marks
-.LP
-\fBm@TMAC_M_PREFIX@m\fP is intended to be international.
-Therefore it is 
-possible to write short national macrofiles which change all
-english text to the preferred language.
-Use \fBm@TMAC_M_PREFIX@mse\fP as an example.
-.\"########################################################################
-.LP
-A file called \fBlocale\fP or \fIlang\fP\fB_locale\fP is read
-after the initiation of the global variables.
-It is therefore
-possible to localize the macros with companyname and so on.
-.sp
-In this manual square brackets is used to show optional arguments.
-.sp 3
-\fBNumber registers and strings\fP
-.br
-Many macros can be controlled by number registers and strings.
-A number register is assigned with the \fBnr\fP command:
-.br
-\fB\&.nr\fP \fIXXX\fP \fI[+-]n [i]\fP
-.br
-\fBXXX\fP is the name of the register, \fBn\fP is the value to
-be assigned, and \fBi\fP is increment value for auto-increment.
-\fBn\fP can have a plus or minus sign as prefix if an increment
-or decrement of the current value is wanted.
-(Auto-increment or decrement
-occurs if the number register is used with a plus or minus sign,

-.SH INTERNALS
-The letter macros is using different submacros depending on
-the letter type.
-The name of the submacro has the letter type
-as suffix.
-It is therefore possible to define other letter types, either
-in the national macro-file, or as local additions.
-\&\fB.LT\fP will set the number variables \fBPt\fP and \fBPi\fP to 0 and 5.
-The following strings and macros must be defined for a new letter type:
-.TP
-\fBlet@init_\fP\fItype\fP
-This macro is called directly by \fB.LT\fP.
-It is supposed to initialize
-variables and other stuff.
-.TP
-\fBlet@head_\fP\fItype\fP
-This macro prints the letter head, and is called instead of the
-normal page header.
-It is supposed to remove the alias \fBlet@header\fP,
-otherwise it will be called for all pages.
-.TP
-\fBlet@sg_\fP\fItype\ name\ title\ n\ flag\ [arg1\ [arg2\ [...]]]\fP
-\&\fB.SG\fP is calling this macro only for letters, memorandums has
-its own processing.
-\fIname\fP and \fItitle\fP is specified
-thru \fB.WA\fP/\fB.WB\fP.
-\fIn\fP is the counter, 1-max, and
-\fIflag\fP is true for the last name.
-Any other argument to \fB.SG\fP
-is appended.
-.TP
-\fBlet@fc_\fP\fItype\ closing\fP
-This macro is called by \fB.FC\fP, and has the
-formal closing as argument.
-.LP
-\&\fB.LO\fP is implemented as a general option-macro.
-\fB.LO\fP demands
-that a string named \fBLet\fP\fItype\fP is defined, where \fItype\fP
-is the letter type.
-\&\fB.LO\fP will then assign the argument to the string
-variable \fBlet*lo-\fP\fItype\fP.

-.SH SYNOPSIS
-.B mmroff
-[
-.I -x
-]
-.I groff_arguments
-.SH DESCRIPTION
-\fBmmroff\fP is a simple preprocessor for \fBgroff\fP, it is
-used for expanding references in \fBm@TMAC_M_PREFIX@m\fP, see
-\fBgroff_mm(@MAN7EXT@)\fP.
-\fBgroff\fP is executed twice, first with \fB-z\fP and \fB-rRef=1\fR
-to collect all references and then to do the real processing
-when the reference file is up to date.
-.TP
-\fB\-x\fR
-Just create the reference file. This can be used to refresh
-the reference file, it isn't always needed to have accurate
-references and by using this option \fBgroff\fP will only
-be run once.

-
-Version 1.1.6-a
-===============
-
-Mom partially broken when run with groff 1.19.1.  Don't know yet
-what this is, whether bad coding in mom, or a problem with 1.19.1.
-Only solution for now: run mom 1.1.6 with groff 1.18.

-========================================================================
-
-KNOWN PROBLEMS
---------------
-
-The indent macros from the typesetting macro set may not always
-perform well in conjunction with the document processing macros,
-especially when documents are set in columns.  Mostly, this is the
-result of inadequate testing.  There are only so many "who'd want to
-do this anyway?" scenarios I can think of on my own.
-
-Epigraphs at the bottoms of page may sometimes run exactly one line
-deeper than they should.  The alternative (from my point of view) is
-to have them run 1 line shorter than they should.  The problem stems
-from the fact the epigraphs are leaded differently than all other text,
-and there's only so much adjusting that can be done with the whitespace
-surrounding them to get them to bottom align.  Since stylistically,
-epigraphs should never appear at the bottom of a page/column without at
-least some running text beneath them in order to make sense of the role
-they play in page layout, this not likely to be fixed for some time.

-
-*Mon May 16 2005
-
-o Update groff_mom.man.
-
-*Thu May 12 2005
-
-o Added margin notes capability
-
-o Added mom-specific refer support; refer calls can be embedded in
-  running text, sent to footnotes or endnotes, or collected for
-  output on a bibliography page; also added mom-specific refer
-  control macros
-
-o Added bibliography page capability, with full suite of control
-  macros
-
-o Added referencing of footnotes and endnotes by line number
-
-o Added capability to have footnotes run on when footnotes are
-  being referenced by line number
-
-o Added a post footnote space option, in case users want a little
-  space between their footnotes
-
-o Added ENDNOTE_MARKER_STYLE, so user can choose between endnotes
-  identified by a numerical marker in the text, or by line number
-
-o Added control macros to accommodate differing needs for endnotes
-  identified by line number
-
-o Added ENDNOTE_TITLE_SPACE, so user can control starting position
-  of the endnotes page title
-
-o Extended LIST so that it accepts lowercase alpha, uppercase roman
-  numeral and lowercase roman numeral enumerators; also added a
-  "prefix" argument (which comes *after* the separator argument)
-
-o Changed RESET_LIST so that it can reset a list to any number,
-  letter, or roman numeral, instead of just 1, a, A, I and i
-
-o Change to handling of footnote/endnote markers in text; input
-  lines before FOOTNOTE still require \c, but input line after
-  FOOTNOTE OFF must be entered as a literal continuation of the
-  line before FOOTNOTE, including any required word space or
-  punctuation (this so users can get the footnote marker in text
-  either before or after the punctuation without hassle)
-
-o Added QUOTE_AUTOLEAD and BLOCKQUOTE_AUTOLEAD, so user can have
-  quotes and blockquotes leaded differently from running text
-
-o Reworked QUOTE and BLOCKQUOTE to accommodate _AUTOLEAD control;
-  spacing above and below quotes is equalized *on a per quote
-  basis* (not completely happy with this, but at least it gives
-  users some flexibility in designing (block)quotes)
-
-*Fri Mar 18 2005
-
-o Added mom.vim to /examples
-
-*Thu Jan 20 2005
-
-o Added \*[TB+] and \*[B] to give inline functionality of .TN and
-  .EL, respectively.
-
-o Added SECTION and SECTION_CHAR as aliases of LINEBREAK and
-  LINEBREAK_CHAR
-
-o Added a NOBREAK option to PAD, so when PAD is called, it's possible
-  to instruct mom not to advance on the page.
-
-*Wed Jan 19 2005
-
-o New macro, ADD_SPACE, so that extra space can be added at the
-  top of a new page in document processing; the .ns call in HEADER
-  was making additional space impossible
-
-o Reworked handling of ALD/SPACE/SP and LS when they're used at
-  the tops of pages during pure (i.e. non-docprocessing)
-  typesetting.  First lines were still wandering.  Should also be
-  more intuitive: ALD after LS advances the specified distance from
-  the top baseline; LS after ALD doesn't change the position of the
-  first baseline (i.e. merely sets the lead for the text that
-  follows).
-
-*Tue Dec 14 2004
-
-o Fixed a small problem with spacing under quotes when paragraph
-  spacing is turned on.
-
-*Fri Dec 10 2004
-
-o Put all calls in VFP_CHECK inside their own environment.  Without
-  the .ev call, the trap invoked VFP_CHECK was chopping off the
-  first word of the last line before footnotes.
-
-*Dec 6 2004
-
-o Small fixes to elvis_syntax.new (dealing with strings, \{\ and \}
-
-o Changed
-    .    ie \\n[#START] \{\
-    .       if \\n[#DOC_HEADER]=0 \{ . \}
-    .    \}
-  in HEAD to
-    .    ie \\n[#START] \{\
-    .       if \\n[#DOC_HEADER]=0 \{ .RLD 1v \}
-    .    \}
-  so that HEADs at the start of docs with no docheaders falls on
-  the correct baseline.
-
-*Dec 3 2004
-
-o Removed spurious parens from if ( \\n[#TRAP_DISTANCE] < \\n[#DOC_LEAD]*2 )
-  in SUBHEAD.
-
-*Oct 14 2004
-
-o Reworked the LL macro so that the argument can take a prepended +
-  or - sign (i.e. the argument is relative to the current line
-  length).
-
-*Oct 13 2004
-
-o Added an .if \\n(.n=0 if to the ie clause in LS that controls how mom
-  responds to initial LS invocation at page top if T_MARGIN has
-  been set.  Now, if there's text on the "top" baseline, LS behaves
-  as expected when invoked afterwards.
-
-*Oct 11 2004
-
-o Added an ie !r#DOCS clause to the processing of "top baseline"
-  ALDs.  ALD is used extensively (internally) in the document
-  processing macros, and does not need to check--indeed, should not
-  check--for top baseline placement prior to execution.
-
-*Sep 29 2004
-
-o Additions to elvis_syntax.new
-
-*Sep 12 2004
-
-o Small fixes to the documentation.
-
-*Aug 21 2004
-
-o Removed superfluous second arguments from strings UP, DOWN, FWD
-  and BCK
-
-*Aug 8 2004
-
-o Version changed from the 1.1.x series to 1.2.  All of the
-  features I originally wanted mom to have originally have been
-  implemented, and appear to be stable.
-
-o Major overhaul to the setting of page traps and the handling of
-  footnotes, both "normal" footnotes and footnotes that occur
-  inside QUOTE, BLOCKQUOTE and EPIGRAPH.
-
-o Addtion of font "styles" to om.tmac, plus changes to the FAMILY
-  and FT macros to manage them.  New section in the doc appendices
-  on adding fonts and managing the new font styles.
-
-o Mom now uses a "fallback font" whenever there's an illegal call
-  to FAMILY.
-
-o RW and EW now affect only the font in effect.  A change of family
-  or font disables them.
-
-o BR_AT_LINE_KERN now properly does a .brp (spread and break) when
-  used in justified text.
-
-o NEWPAGE, which used to be an alias for .bp, has been moved into
-  its own macro, in order to make it more responsive to some unusal
-  situations.
-
-o Some changes to elvis_syn.new, including that the file extensions
-  recognized by elvis now include both .mom and .tmac.  This makes
-  om.tmac much easier to read.
-
-*Jul 6 2004
-
-o FT and FAM(ILY) reworked to take advantage of if S, if F and
-  \n[.sty] additions to groff (1.19.2).  Warnings are emitted if a
-  style hasn't been registered, or if a font style doesn't exist in
-  the current family.  Invalid .FAM(ILY) calls now use a "fallback"
-  font" (although no warning is issued); fallback is user-settable
-
-o New macro, FALLBACK_FONT.  Not only controls the fallback font
-  for invalid family calls, but also controls whether mom aborts on
-  invalid .FT calls after issuing a warning.
-
-o RW/EW now affect only the current font (or font style)
-
-o BR_AT_LINE_KERN now (properly) does a break-and-spread when text
-  is justified.
-
-o Fairly extensive list of .sty's added to om.tmac.  Hopefully,
-  this will make life easier for users wishing to add new fonts
-  and/or entire new families to their groff site-font/devps
-  directory.
-
-*Jun 6 2004
-
-o Altered kerning slightly for footnote markers in text.  Daggers
-  and double-daggers were getting a bit jammed 
-
-*Fri Jun 4 2004
-
-o Makefile.sub (HTMLDOCFILES, EXAMPLEFILES, PROCESSEDEXAMPLEFILES): Updated.
-
-*Thu Jun 3 2004
-
-o Rewrote the routines dealing with _FAMILY, _FONT, _SIZE, _COLOR
-  and _QUAD.  A single macro for each checks for the calling alias
-  (e.g. TITLE_FAMILY in _FAMILY), and performs the appropriate
-  action.
-
-o All "COLOUR" aliases of "COLOR", no matter where, have been
-  removed.
-
-o Added cover and doc cover page generation.
-
-o Added reference macros COVERTITLE, DOC_COVERTITLE, MISC and
-  COPYRIGHT (for use with covers only)
-
-o Fixed EL and TN so they don't spring page traps; in nofill modes
-  the preceding input line must be terminated by \c.
-
-o Added #T_MARGIN_LEAD_ADJ to DO_B_MARGIN, DO_T_MARGIN and NEWPAGE
-  to ensure accurate placement of first lines on new pages when
-  docprocessing is not taking place.
-
-o Made NEWPAGE it's own macro; formerly just an alias of .bp.
-
-o Made BREAKQUOTE obsolete; rewrote sections of footnote handling,
-  including adding support macros to deal with processing of
-  footnotes that were started inside quotes, blockquotes and
-  epigraphs.
-
-o Added a TERMINATE .em to docprocessing (except letters) to ensure
-  that deferred footnotes print on the last page of a doc.
-
-
-*Mar 15 2004
-
-o Added color support
-
-o Adjusted vertical placement of hyphens around page numbering
-  so that they are better centered on the height of the page
-  number.
-
-o Re-wrote portions of the document processing macros so that tabs
-  behave in a consistent and intuitive manner.  Tab structures are
-  now properly preserved from page to page and column to column.
-
-*Feb 20 2004
-
-o Rewrote the macros associated with DOCTYPE LETTER so that the
-  user can enter DATE, TO and FROM in any order s/he likes.  For
-  backward compatibility, if the older, fixed order (DATE-TO-FROM)
-  is used, the date goes flush right with two linespaces after
-  it, while the other fields go flush left with a single linespace
-  separating them.
-
-o Fixed handling of DOCHEADER OFF <distance> when <distance> fell
-  short of the top margin of running text (the change is actually
-  in the SHIM macro, which is called by DOCHEADER).
-
-o Added a selection of iso 639 two-letter language codes as
-  optional arguments to SMARTQUOTES, so that the use can enter
-  her/his language code to get language specific quoting styles
-
-o Changed the way the strings for \*[ST<n>], \*[ST<n>X], \*[FU<n>]
-  and \*[BU<n>] are read.  Formerly, they were entered literally.
-  Now they're entered as an array.
-
-*Jan 24 2004
-
-o Added lists and associated macros.  Mom now does (nested) lists.
-
-o Added German-style lowered double quotes and two styles of
-  guillemets to SMARTQUOTES.
-
-o Added macro SIZE, intended to be called inline as \*[SIZE <n>].
-  This is to bring mom's inline size change syntax into line with
-  her other inlines.
-
-o Added ESC_CHAR as an alias of .ec
-
-o Added doc entries for lists.
-
-o Updated SMARTQUOTES entry in docs.
-
-o Updated reserved words in docs.
-
-o Fixed a few more typos in docs.
-
-*Tue Oct 21 2003
-
-o Changed \n[#DRAFT] and \n[#REVISION] to strings \*[$DRAFT] and
-  \*[$REVISION], allowing for the possibility of blank entries that
-  don't mess up headers/footers with zeros if user doesn't want any
-  numbers.
-
-o Extended handling of draft and revision numbers and strings in
-  headers/footers for increased flexibility.  It's possible now to
-  have just about any combo of DRAFT_STRING, DRAFT, REVISION_STRING
-  and REVISION, and have them come out in headers/footers as one
-  intuitively expects/wants.
-
-*Fri Jul 25 2003
-
-o Added a .bp after .if \\n[#START]=1 in FOOTER.  Without it,
-  in document processing mode, documents that use *none* of the
-  docprocessing tags (yes, there are times when users want to do
-  this) ignored the footer trap.
-
-*Fri Jun 6 2003
-
-o Changed register #DOCHEADER_LEAD_ADJ to string
-
-*Wed May 21 2003
-
-o DOC_TITLE changed to be used exclusively with DOCTYPE DEFAULT
-
-o Fixed problem with restoration of previous doc pagenum
-  style when endnotes use a different pagenum style (set with
-  ENDNOTES_PAGENUM_STYLE)
-
-o Fixed handling of headers/footers with respect to endnotes.  Now,
-  when either headers or footers are on, mom picks up the correct
-  page header/footer on the last page prior to ENDNOTES, gets the
-  pageheaders correct for endnotes pages *including the last one*,
-  and picks up correct page headers/footers for the subsequent docs
-  after COLLATE
-
-*Sat May 17 2003
-
-o Added TOC (finally) and a nearly complete set of associated
-  control macros
-
-o Added new control macros to endnotes:
-
-  ENDNOTES_STRING_CAPS       - capitalize the endnotes string
-  ENDNOTES_NO_COLUMNS        - allows docs in columns and endnotes not
-  ENDNOTES_PAGENUM_STYLE     - set page numbering style for endnotes
-  ENDNOTES_FIRST_PAGENUMBER  - set first pagenumber for endnotes
-  ENDNOTES_ALLOWS_HEADERS    - page headers on endnotes pages off or on
-  ENDNOTES_NO_FIRST_PAGENUM  - allows non-printing first page number when page footers are being used instead of headers
-  ENDNOTES_SINGLE_SPACE      - for TYPEWRITE, if doc double-spaced
-  SUSPEND/RESTORE_PAGINATION - turns page numbering off for endnotes
-
-o Added an ADJUST option to ENDNOTE_LEAD
-
-o Added DOC_TITLE (like TITLE, but sets document-wide title for collated docs)
-
-o Added HDRFTR_CENTER_PAD, to allow adjustments to placement of
-  HDRFTR_CENTER_STRING
-
-o Added BLANKPAGE macro, to output blank pages (silently numbered)
-
-o Extensive changes to DEFAULTS, START, COLLATE, HEAD, SUBHEAD and
-  PARAHEAD because of new TOC and extended flexibility of ENDNOTES
-  page design
-
-o Fixed DOCHEADER OFF (distance), FINIS
-
------------------------------------------------------------------------
-
-*Sat Feb 22 2003
-
-o (Re)-fixed handling of post epigraph spacing after #START for
-  TYPEWRITE double-spaced.
-
-------------------------------------------------------------------------
-
-*Sun Feb 16 2003
-
-o Added James Ramsey's proposed CHAPTER_TITLE macro, along with his
-  rewritten START macro and his utility macros to make START easier
-  to read.
-
-o Expanded handling of CHAPTER_TITLE to encompass TYPEWRITE, as well as
-  plugging it into the docheaders.  Made CHAPTER_TITLE backwardly
-  compatible so that pre-1.1.5 docs using CHAPTER_STRING to create a
-  chapter title remain unaffected when groffed with 1.1.5.
-
-o Created control macros for CHAPTER_TITLE FAMILY, FONT and SIZE.
-  Added defaults for handling of CHAPTER title to DEFAULTS.  Documented
-  CHAPTER_TITLE and everything that goes along with it.
-
-o Fixed broken draft and revision in headers/footers.
-
-o Fixed \*[RULE] so that it behaves properly with indents and justified
-  copy.
-
-o Fixed/tweaked handling of epigraph spacing in TYPEWRITE.
-
-o Fixed broken spacing of docheaders in TYPEWRITE.
-
-*Mon Feb 3 2003
-
-o Fixed an oversight in CLOSING for DOCTYPE LETTER (closing wasn't
-  being set flush left)
-
-*Sun Sep 29 2002
-
-o Changed .ne in .HEAD when PRINTSTYLE TYPESET from 5 to 4.  With 5,
-  heads required at least 2 lines of text underneath or they'd be
-  defered to the next page, which created too much whitespace at the
-  end of the page.  Heads will now be processed on the same page if the
-  head plus at least one line of text underneath fits.  I figure it's
-  easier for the user to break to a new page manually if this behaviour
-  is unsatisfactory than to massage the page to fix the excess
-  whitespace.
-
-*Sun Aug 25 2002
-
-o Changed .IX to .IQ.  The older form still works, but emits a message
-  advising the user to update to the newer.  (The macro in om.tmac
-  still remains IX; IQ is an alias.)  Docs updated to reflect the
-  change.
-
-*Tue Aug 20 2002
-
-o Added new (better) way to handle inline kerning.  \*[BU #] and
-  \*[FU #] allow passing an argument to the inline string.  The older
-  forms \*[BU#] and \*[FU#] still work, though.
-
-o Changed handling of inline horizontal and vertical movements.
-  Horizontal movements are now done with \*[BCK #<unit>] and
-  \*[FWD #<unit>]; verticals with \*[UP #<unit>] and \*[DOWN #<unit>].
-  The older forms \*[FP#] and \*[BP#] still work (horizontals), as do
-  \*[ALD#] and \*[RLD#] (verticals).
-
-------------------------------------------------------------------------
-
-*Mon Aug 19 2002
-
-o Fixed ENDNOTES so footnotes output properly when ENDNOTES is called
-
-o Added ENDNOTES_HDRFTR_CENTER so that default no-print of header
-  center string on endnotes page(s) when DOCTYPE is CHAPTER can
-  be disabled (i.e. header center will be printed).
-
-*Sat Aug 10 2002
-
-o Added .nf to top of PAD, with a test beforehand for current fill
-  mode.  If fill mode was on, it's restored after PAD completes
-  processing.  Updated reserved.html to include number register
-  #FILL_MODE.
-
-*Fri Jul 12 2002
-
-o More fixes to underlining.
-
-*Fri Jul 5 2002
-
-o Added capability of endnotes and pertinent control macros to om.tmac.
-
-o Added document entries pertaining to endnote macros.
-
-o Incorporated endnote macros into elvis_syntax.
-
-o Small doc fixes.
-
-o Tidied up indenting of om.tmac.
-
-o Fixed handling of underlining of italics in PRINTSTYLE TYPEWRITE
-  (there was a problem with footnotes getting underlined when they
-  shouldn't have been).
-
-o Removed ENDNOTES from TODO
-
-o Fixed the character translations for UNDERLINE so they work properly
-  with digraphs.
-
-*Mon Jul 1 2002
-
-o Expanded docprocessing.html entry "Special Note on Chapters".  Tidied
-  up html a bit.
-
-*Sat Jun 15 2002
-
-o Small fix to PAD to make the use of inlines within the pad string
-  more intuitive.
-
-o Added \*[RULE] ( = \l'\n(.lu' ) so that full measure rules (either to
-  full line length or within tabs) are easier to set.
-
-*Sat Jun 8 2002
-
-o Macro .PS renamed to .PT_SIZE.  Alias .TS removed.
-
-o .tr bits in .CAPS rewritten in the form .tr é\[`E].
-
-o General cleanup of docs to reflect changes
-
-o Small changes/additions to elvis_syn
-
-*Thu Jun 6 2002
-
-o In DOCTYPE, in .if '\\$1'LETTER', added .FOOTER_RIGHT_SIZE +0.
-  Without it, the suite page was printing at the default
-  FOOTER_RIGHT_SIZE of -.5, which didn't look good.
-
-*Wed Jun  5 2002
-
-o Makefile.sub (TFLAG): Add `$(top_builddir)/tmac'.
-
-*Tue Jun  4 2002
-
-o Makefile.sub (groff_bin_dirs): Fix typo (forgotten `src' element).
-
-*Mon Jun  3 2002
-
-o Makefile.sub (uninstall_sub): Don't use `momdocdir' but `htmldocdir'.
-  Add missing backslash.
-
-*Sat Jun  1 2002
-
-o Makefile.in (prepare_make_examples): Test for `penguin.ps', not
-  `examples/penguin.ps'.
-
-*Wed May 29 2002
-
-o Rewrote portions of PAGENUM_STYLE and COPYSTYLE so that PAGENUM_STYLE
-  behaves as advertised.
-
-*Fri May 24 2002
-
-o /Makefile.sub (momdocdir): Removed.
-  (HTMLDOCFILES): Prepend `momdoc/'.
-  (EXTRAEXAMPLEFILES): Removed.  Added entries to...
-  (EXAMPLEFILES): This.
-  (.SUFFIXES, .mom.ps): New.
-  (prepare_make_examples): Updated.
-  (examples/*.ps): Removed; .mom.ps will handle this.
-  (install_data): Updated.  
-
-*Thu May 23 2002
-
-o Applied two small bug fixes to om.tmac (patches 1.1.1a and 1.1.1b).
-
-o mom is now part of groff.
-
-o Some renaming to avoid problems with 8+3 filesystems:
-
-    examples/docprocessing_typeset.mom   -> examples/typeset.mom
-    examples/docprocessing_typewrite.mom -> examples/typewrite.mom
-    examples/typesetting_macros.mom      -> examples/macros.mom
-    examples/penguin_small2_bw.ps        -> examples/penguin.ps
-
-o Removed `INSTALL' and `README' since groff takes care of installation
-  now.
-
-o Added Makefile.sub.
-
-o Added mom.tmac (which simply calls om.tmac).
-
-o Added groff_mom.man for orthogonality; it simply points to the HTML
-  documentation.
-
-*Thu May 16 2002
-
-o Added macro DRAFT_WITH_PAGENUMBER so user can have draft/revision
-  info attached to the pagenumber in COPYSTYLE DRAFT, instead of having
-  it HEADER center.  Always having it HEADER center was creating problems
-  with long doc titles, esp. with PRINTSTYLE TYPEWRITE (which is when
-  COPYSTYLE DRAFT is most likely to be used).  Now user has the choice,
-  in these circumstances, either to reduce HEADER_SIZE, or to displace
-  the draft/revision info.  Also rewrote portions of COPYSTYLE so that
-  if no revision number is given in the reference macros, "Rev. #"
-  doesn't appear when COPYSTYLE DRAFT.
-
-*Fri May 10 2002
-
-o Added capability of user-defined, single string recto/verso
-  headers/footers.
-
-o Added new entries to docs about the above.  Made some additional
-  small changes to toc.html, rectoverso.html, and headfootpage.html
-  to supplement the new entries.
-
-o Small fix to handling of footer separator rule -- was 1 point too low
-  owing to fuzziness of #CAP_HEIGHT as returned by SIZESPECS.
-
-o Added some more useful stuff to elvis_syntax.
-
-*Sun May 05 2002
-
-o Fix to DEFAULTS so that L_MARGIN and R_MARGIN are reprocessed if
-  DOCTYPE LETTER.  R_MARGIN, as set by DOCTYPE LETTER had no preceding
-  PAGEWIDTH or PAPER from which to get #PAGE_WIDTH for figuring out
-  line length.
-
-o Additional fix to DEFAULTS in handling DOCTYPE LETTER so that if user
-  sets line length prior to START, no reprocessing of R_MARGIN occurs.
-  This necessitated adding a new number register: #USER_SET_L_LENGTH
-
-*Sat May 04 23:48:05 EDT 2002
-
-o Added .cflags 4 /\(en -- was driving me nuts that lines wouldn't
-  break after these characters; I'm assuming others feel the same way
-
-* Fri May 03 2002
-
-o Made some small fixes to space handling around quotes, mostly to do
-  with quotes immediately after START and quotes after (sub)heads.
-
-* Wed May 01 2002
-
-o Fixed a small bug that was causing the first .PP after START to begin
-  at the top margin of the page regardless of any type that preceded
-  .PP when docheaders were off.
-
-o Fixed HEADER so that when HEADERS are off the first line of type on
-  pages after the first falls properly at the top margin
-
-*Sat Apr 27 2002
-
-o Renamed docprocessing_macros.mom in /examples to
-  docprocessing_typeset.mom.  Added docprocessing_typewrite.mom, as
-  well as a README file.
-
-o Fixed UNDERLINE_QUOTES (for PRINTSTYLE TYPEWRITE) so they really are
-  on by default as the docs say.
-
-o Changes to doc entry on COLLATE:
-
-    - removed bit about using COLLATE after a cover page (I wrote the
-      entry *before* I wrote the macro!).  Cover pages should be
-      followed by NEWPAGE, not COLLATE.
-
-    - added caution about mixing PRINTSTYLEs
-
-    - added caution about using DOC_FAMILY to change family of all
-      document elements after COLLATE
-
-o Made HEADER_SIZE (and, by extension, FOOTER_SIZE) available to
-  PRINTSTYLE TYPEWRITE.  Changed appropriate doc entries to reflect
-  this.
-
-*Wed Apr 24 2002
-
-o Small change to DO_QUOTE to correct a problem with quotes and
-  blockquotes that fall in the middle of paragraphs (i.e. text after
-  the quote is not a new para).  Basically, added a bit that stores the
-  current para indent, sets para indent to 0, invokes a PP, then
-  restores the original para indent.
-
-o Added new macro, BREAK_QUOTE, to deal with the problem of
-  footnotes in quotes and blockquotes that cross pages or columns.
-
-  Quotes and blockquotes are read into diversions, which means they
-  get their footnote information from the page/column on which they
-  were started.  If a footnoted quote crosses a page/column, what
-  sometimes happens is that the footnote itself is output at the
-  bottom of page/column where the quote started, whereas the text
-  marker for the footnote appears on the next page/column where the
-  quote ends.  Furthermore, the text marker is the one appropriate
-  to the previous page.  BREAK_QUOTE is a workaround.
-
-o Added directory /examples to archive.
-
-o Added typesetting_macros.mom, docprocessing_macros.mom, elvis_syntax
-  and penguin_small2_bw.ps to /examples.
-
-o Added BREAK_QUOTE to docs, made some additions to reserved words
-  list, and corrected a few little doc errors.
-
-*Mon Apr 22 2002
-
-o Added default .L_MARGIN 1i and .R_MARGIN 1i to PAPER, PAGE, and
-  PAGEWIDTH.  L_MARGIN is essential otherwise left indents and tabs
-  don't have a register #L_MARGIN to work with.  The default right
-  margin is a convenience only.  Updated the doc entries for L_MARGIN
-  and R_MARGIN to reflect the change.
-
-*Sun Apr 21 2002
-
-o Changes to COLLATE:
-
-    - added some "resets" (LL, LS, QUAD)
-    - added a check for whether pagination is at page top (either
-      because FOOTERS are on or because PAGENUM_POS was user set).
-      If pagination is on, and PAGENUM_POS is TOP, it's turned off
-      for next page (start of next collated document) and restored
-      for subsequent pages unless PAGENUM_ON_FIRST_PAGE is on, in
-      which case the page number appears at page top.
-
-o The macro TRAPS is always invoked at the end of DEFAULTS (which is
-  called by START).  Formerly, TRAPS was only invoked at the start
-  of a doc, not after COLLATE.  Now runs after COLLATE as well.
-
-o Distance from $DOC_TYPE in DOCTYPE NAMED "<string>" to start of
-  running text was one linespace too deep.  Fixed (in START).
-
-o When 1st arg to PAGENUM_POS was user set to TOP, running text was
-  printing 1 linespace too high, even when PAGINATION was OFF.  Same
-  problem when HEADERS were OFF (i.e. nothing in the header margin at
-  all).  Fixed by removing -\\n[#DOC_LEAD]u from all .sp |\\n[#T_MARGIN]u
-  calls of .el portion after .ie \\n[#HEADERS_ON].
-
-o Added new macro: PAGENUM_ON_FIRST_PAGE.  Normally, when FOOTERS are
-  being used instead of HEADERS, mom doesn't print the page number at
-  the top of the first page of a doc, or the first page of collated
-  docs.  New macro allows user to get mom to put the page number on
-  "first" pages if that's desired.  Updated docs to include the macro.
-
-o More little fixes to docs.
-
-*Thu Apr 18 2002
-
-o Fixed TI (temporary indent) so that it continues to work as expected,
-  even when called while another type of indent is in effect.
-
-*Tue Apr 16 2002
-
-o String tabs weren't working as advertised when set from within
-  a tab.  Fixed.  Two new registers added: #ST_OFFSET and #IN_TAB.
-  String tabs now behave poperly and intuitively when set within tabs.
-
-o Added a note to docs about surrounding \w'...' escape with double-
-  quotes when it's used as an argument to macros
-
-o Added a note to docs that SILENT does not deposit a .br
-
-*Mon Apr 15  2002
-
-o Added new macro BR_AT_LINE_KERN if user wants mom to deposit .br's
-  before .RW and/or .EW.
-
-o Added 1/4 points to inline escapes \*[ALD] and \*[RLD].
-
-o Added 1/4 points to inline escapes \*[FP] and \*[BP]
-
-o Updated docs to reflect the above changes.
-
-*Fri Apr 12 2002
-
-o Fixed .RW and .EW which weren't working because of a missing \ in
-  \\n(.f register.  Also made it so that .RW and .EW affect all fonts
-  in positions 1, 2, 3, and 4 at once, hence line kerning now affects
-  all fonts that appear after it, not just the font that was current at
-  the time of the macros' invocation.
-
-o .SS and .WS now working properly.  .WS no longer has any effect on
-  .SS, which remains constant regardless of .WS.  Furthermore, .SS no
-  longer gets its value by adding \*[$SS_VAR] + \n[.ss].  Instead,
-  it remains constant.  Don't know what I was thinking when I wrote
-  the routine in the first place.
-
-o Updated and rewrote doc entry pertaining to SS
-
-*Wed Apr 10 2002
-
-o Renamed tmac.om to om.tmac to bring macro file's name into line
-  with current groff policy
-
-o Added more standard paper sizes to PAPER.
-
-o Fixed T_MARGIN, LS, and AUTOLEAD so that if T_MARGIN is set before LS
-  or AUTOLEAD at the top of a file, the first line of type falls
-  properly on the baseline set by T_MARGIN.  Previously, LS and
-  AUTOLEAD automatically advanced by the value passed to them before
-  setting the first line of type, meaning that the first line of type
-  fell at T_MARGINu+1v instead of T_MARGIN.
-
-o Updated docs to reflect changes.
-
-o Removed #TEST_FOR_NUMERIC from list of reserved words.
-
-o Added "t" and #T_MARGIN_SET to list of reserved words.
-
-*Sat Apr 6 2002
-
-o Added FACTOR arg to AUTOLEAD, so if user wants autolead to be a factor
-  of point size, instead of being the sum of pointsize + autolead, s/he
-  has the choice.  Incorporated appropriate changes to PS and LS.
-
-o Added new register #AUTOLEAD_FACTOR to reserved words.  Modified
-  comments for AUTOLEAD, PS, and LS to reflect changes.  Also
-  corrected an error where #AUTOLEAD_VALUE had mistakenly been written
-  $AUTOLEAD_VALUE in comments in the macro file, and removed erroneous
-  | <anything>.  Updated AUTOLEAD entry in momdoc/typesetting.html
-  to reflect the changes.
-
-*Wed Apr 3 2002
-
-o Cleaned up html errors in the docs.
-
-o Added "Next," "Prev" and "Top" links to top and bottom of doc files.
-
-o Fixed some typos in the docs.

-Release 1.3
------------
-
-Added line numbering capabilities, with controls.
-
-Footnotes and endnotes can now be referenced by line number.
-
-Added ability to adjust vertical position of the title that appears
-on the first endnotes page.
-
-Footnotes can run on when being referenced by line number.
-
-Footnotes now have a post-footnote spacing option, for adding
-a little space between footnotes.
-
-Extended LIST so it accepts alpha, ROMAN and roman enumerators.
-
-Added margin notes capability.
-
-Added refer support.
-
-Added bibliography page support.
-
-Added QUOTE_AUTOLEAD and BLOCKQUOTE_AUTOLEAD, so user can have
-quotes and blockquotes leaded differently from running text.
-
-Change: the input line immediately after FOOTNOTE OFF must be
-entered as a literal continuation of the line prior to FOOTNOTE,
-including any initial spaces or punctuation marks.  This allows
-for hassle-free placing of footnote markers in running text either
-before or after punctuation marks.
-
-Release 1.2-f
--------------
-
-Added ADD_SPACE, to permit users to insert space at the top of
-running text (after the first page) when using the docprocessing
-macros.
-
-Releases 1.2-a and 1.2-b
-------------------------
-
-My personal email address has changed.  1.2-a and -b have been
-updated to reflect that.  Additionally, I made some small changes
-to the documentation.
-
-Release 1.2
------------
-
-As of 1.2, the recommended version of groff to use with mom has
-been bumped up from groff, 1.18 to groff, 1.19.2.  Although mom will
-continue to work with groff, 1.18, her handling of .FAM(ILY) and .FT
-is now slightly different, therefore users of groff 1.18 may have to
-update documents created with mom so that every .FAM(ILY) request is
-followed by a .FT request before any text is input, otherwise mom
-will set the text after .FAM(ILY) in Courier (until she encounters a
-.FT request).  People running groff, >= 1.19.2 don't have to worry
-about this, but I recommend that, regardless of which version you're
-running, you have a look at the document entries for FAMILY and FT
-in order to see how mom will be handling .FAMILY and .FT from now
-on.
-
-When used with groff >=1.19.2, mom now emits warnings if a style
-hasn't been registered, or if a font style doesn't exist in the
-current family.  Invalid .FAM(ILY) calls now use a "fallback" font"
-(although no warning is issued).  The fallback is user-settable.
-
-Mom's macro file, om.tmac, now sets up a fairly extensive list of
-font "styles," thus expanding the range of arguments that can be
-passed to .FT (formerly, just R, I, B and BI, unless users had
-already rolled their own solution to the problem of extensive type
-families containing fonts like condensed, demibold, black, light, etc).
-Users are advised to read the documentation sections on FAM(ILY),
-FT and FALLBACK_FONT, as well as the new appendix section, "Adding
-PostScript fonts to groff", for information on using mom's style
-extensions (and how to disable them, should they conflict with a
-user's present groff site-font/devps setup).
-
-A new macro, FALLBACK_FONT, has been added.  It controls not only
-the fallback font for invalid .FAMILY calls, but also whether mom
-aborts on invalid .FT calls after issuing a warning, or continues
-processing using the fallback.
-
-Release 1.1.9
--------------
-
-Added the (optional) generation of cover pages and document cover
-pages, plus a full suite of control macros for all cover page
-elements.
-
-Added new reference macros that apply to covers: COVERTITLE,
-DOC_COVERTITLE, COPYRIGHT and MISC.
-
-The need for TRAP OFF/TRAP to deal with ELs and TNs that fall at
-the bottom page has been obsoleted.  However, both EL and TN, when
-invoked in any "nofill" mode (LEFT, RIGHT, CENTER, or the L | R | C
-arguments to TAB_SET or ST when no QUAD argument is given), must now
-have the input line preceding the EL or TN terminated by \c.  Fill
-modes do not have this requirement, i.e. no \c is required.
-
-Footnotes that occur inside quotes, blockquotes and epigraphs now
-work just like regular footnotes, with no user intervention
-required.  This obsoletes the macro BREAK_QUOTE.
-
-Removed all aliases that used the word COLOUR.  Users must use
-COLOR wherever COLOR is needed.  COLOUR, as a replacement/alias, is
-no longer supported.
-
-NEWPAGE, which used to be an alias of .bp, is now its own macro.
-
-Release 1.1.8
--------------
-
-Added text color support.  Users can now define or initialize a color,
-and afterwards change text color with an inline of the form
-\*[<colorname>], or with the macro .COLOR.  In document processing,
-the docelement tag control macros have been expanded to include
-_COLOR, e.g. .HEAD_COLOR <predefined colorname> will colorize
-heads, PAGENUM_COLOR <predefined colorname) will colorize page
-numbering, etc.
-
-Adjusted vertical placement of hyphens around page numbering when
-PAGENUM_STYLE is DIGIT, ROMAN or ALPHA so that the hyphens appear
-properly centered on the page numbering character.
-
-Changed tab handling in document processing so that tab structures
-are preserved from page to page and column to column.
-
-Release 1.1.7-a
----------------
-
-Increased the flexibility of SMARTQUOTES so that they handle quoting
-styles by language, entered as a 2-digit language code argument to
-SMARTQUOTES.  See docs.
-
-Re-wrote the DOCTYPE LETTER macros so that DATE, TO and FROM can be
-entered in any order the user wishes, with output that matches
-input.  (Should have done this in the first place.)
-
-Release 1.1.7
--------------
-
-Finally got around to writing "list" macros.  See the docs.
-
-Added German-style lowered double quotes and two styles of
-guillemets to SMARTQUOTES.
-
-Added macro SIZE, intended to be called inline as \*[SIZE <n>].
-This brings mom's inline size change syntax into line with her other
-inlines.  \*S[<n>] can still be used for the same thing.
-
-The file elvis_syntax (for elvis prior to 2.2h) is no longer being
-maintained.  It was getting messy and long in the tooth.  The
-official elvis syntax file is elvis_syntax.new, which works for
-2.2h of elvis (and higher, one hopes).  elvis users are encouraged
-to update to 2.2h or higher.
-
-Release 1.1.6-e
----------------
-
-Extended handling of draft and revision numbers and strings in
-headers/footers for increased flexibility.  It's possible now to
-have just about any combo of DRAFT_STRING, DRAFT, REVISION_STRING
-and REVISION, and have them come out in headers/footers as one
-intuitively expects/wants.
-
-Also added a new set of syntax highlighting rules for the vi clone,
-elvis.  Version 2-2h-beta of elvis finally made possible the
-highlighting of \*[...] inline escapes, whether or not they're
-separated from surrounding text by spaces.  This is a terrific
-improvement in elvis, and makes for greatly improved readability of
-mom files.
-
-Release 1.1.6-b - 1.1.6d
-------------------------
-
-Trivial changes to documentation and some cleanups of the main
-om.tmac file, including:
-
-Added a .bp after .if \\n[#START]=1 in FOOTER.  Without it,
-in document processing mode, documents that use *none* of the
-docprocessing tags (yes, there are times when users want to do
-this) ignored the footer trap.
-
-Changed register #DOCHEADER_LEAD_ADJ to string
-$DOCHEADER_LEAD_ADJ.  This means that .DOCHEADER_LEAD no longer
-requires a unit of measure; points is assumed.
-
-Release 1.1.6-b
----------------
-
-Added a SHIM macro that calculates and moves to the next "legal"
-baseline during document processing (useful if user starts playing
-around with spacing/leading on a page and needs to get the leading
-back on track).
-
-Fixed handling of DOCHEADER OFF <distance> so that the first line of
-running text falls on a "legal" baseline when <distance> is given.
-
-Release 1.1.6-a
----------------
-
-Problem with groff 1.19.1 fixed by Werner (.return handled arguments
-incorrectly).
-
-Fixed handling of page numbering style restoration in endnotes, so
-that (collated) docs have the correct page numbering style when the
-style has been changed for endnotes (with ENDNOTES_PAGENUM_STYLE).
-
-DOC_TITLE has been made for use exclusively with DOCTYPE DEFAULT.
-
-Fixed handling of headers/footers with respect to endnotes.  Now,
-when either headers or footers are on, mom picks up the correct
-page header/footer on the last page prior to ENDNOTES, gets the
-pageheaders correct for endnotes pages *including the last one*, and
-picks up correct page headers/footers for the subsequent docs after
-COLLATE.
-
-
-Release 1.1.6
--------------
-
-BAD NEWS: mom appears to be crippled in some areas when run with
-groff 1.19.1.  Pending a solution, mom must be run with groff 1.18
-
-***NEW***
-
-Added TOC capabilities.
-
-Extended range of endnotes control macros.  See the documentation
-on endnotes control macros.
-
-Added a new DOC_TITLE macro, to deal with collated documents that
-have an overall title, while each doc has its own separate doc
-title (from TITLE).
-
-
-Release 1.1.5
--------------
-
-***NEW***
-
-Added James Ramsey's CHAPTER_TITLE macro as well as control macros to
-go with it.  Thanks James.  Also from James came a patch to handle
-START differenty which has been incorporated into om.tmac.  Thanks
-again, James.
-
-Some bits and pieces of the docs have been tweaked, but nothing
-changed.  Hopefully, the changes will make parts of the docs easier to
-read and navigate.
-
-***FIXES***
-
-o \*[RULE]
-
-o broken draft and revision in docheaders
-
-o post-epigraph spacing in TYPEWRITE
-
-o header spacing in TYPEWRITE
-
-------------------------------------------------------------------------
-
-Release 1.1.4
--------------
-
-***SIGNIFICANT CHANGE***
-.IX is now deprecated, although it will continue to work as before.
-The new form is .IQ (Indent Quit).  Groff will emit a message advising
-users to update their docs.
-
-***NEW***
-Four new inlines to deal with horizontal and vertical movements:
-
-    o \*[FWD n]
-    o \*[BCK n]
-    o \*[UP n]
-    o \*[DOWN n]
-
-All four require a unit of measure after n.  These inlines are similar
-to the older \*[FPn], \*[BPn], \*[ALDn] and \*[RLDn], however they're
-not restricted to points, and any value can be entered for n (the older
-forms -- which still work -- were restricted to 1 - 36).
-
-***CHANGED***
-Inline kerning can now be accomplished with \*[BU n] and \*[FU n], where
-n, after the space, is the desired number of kern units.  The older
-forms \*[BUn] and \*[FUn] still work, up to 36 units.
-
-------------------------------------------------------------------------
-
-Release 1.1.3c
---------------
-
-***NEW***
-A new macro -- ENDNOTES_HDRFTR_CENTER -- added so that mom's default
-behaviour of not printing the header center string when DOCTYPE is
-CHAPTER can be disabled (i.e. she will print the center string).  The
-macro is user-called with ENDNOTES_HEADER_CENTER or
-ENDNOTES_FOOTER_CENTER.
-
-***FIXES***
-PAD now works as advertised when fill mode is on.
-
-ENDNOTES no longer disables printing of footnotes on last page of
-document body.
-
-Release 1.1.3
--------------
-
-***SIGNIFICANT CHANGE -- PLEASE TAKE NOTE***
-As of 1.1.3, groff must be >= 1.18.
-
-***NEW***
-Added endnotes functionality to mom, along with a slew of macros to
-control how mom prints endnotes pages.  See the html documentation.
-
-***NEW***
-Added inline \*[RULE], which draws a rule to the full measure of the
-current line length ( to be used in place of \h'\n(.lu' ).  Weight of the
-rule is dependent on the point size of type when \#[RULE] is called.
-
-***FIXES***
-PAD -- works more intuitively now when the pad string contains inline
-escapes for font, point size, etc.
-
-UNDERLINE -- fixed character translations of digraphs so they get
-underlined properly.  Also fixed a bug that was causing some footnotes
-to get underlined when UNDERLINE was on in the body of the document.
-
-***UPDATES***
-Html documentation
-elvis_syn
-
-Release 1.1.2a
---------------
-
-***SIGNIFICANT CHANGE -- PLEASE TAKE NOTE***
-In order to help mom toward full groffship, the macro .PS has been
-renamed to .PT_SIZE, and the alias .TS (for .TAB_SET) has been removed.
-.PS and .TS are keywords used by pic and tbl respectively, and the mom
-macros of the same name were in conflict.
-
-Release 1.1.2
--------------
-
-***IT'S OFFICIAL!***
-mom is now an official part of the groff.  New releases will be
-incorporated into the groff package.  I'll still be posting each new
-release on the mom homepage, so there's no need to download all of the
-most recent version of groff just to get a newer mom. :)
-
-***CHANGES***
-Fixed default footer separator rule adjustment so that it's closer to
-the advertised "4 points above the tallest ascender in the footer."
-
-Added more stuff to the elvis_syn file.  Still wouldn't mind someone
-contributing some vim/emacs syntax highlighting.
-
-Added .cflags 4 /\(em to om.tmac.  By default, mom now obligingly
-breaks after / and \(en.
-
-***NEW***
-Macro(s): HEADER_RECTO
-          HEADER_VERSO
-With these macros, users can now define single-string recto/verso
-headers/footers.  HEADER_RECTO (or FOOTER_RECTO) can be used to create
-a one-part header/footer (instead of mom's default three-parters) that
-appears on every page if RECTO_VERSO is OFF or, if RECTO_VERSO is on, if
-no HEADER_VERSO (or FOOTER_VERSO) has been defined.  If a HEADER_VERSO
-(or FOOTER_VERSO) is defined and RECTO_VERSO is on, _RECTO prints on
-even pages and _VERSO on odd pages.
-
-Added macro DRAFT_WITH_PAGENUMBER so user can have draft/revision
-info attached to the pagenumber in COPYSTYLE DRAFT, instead of having
-it HEADER center.  Always having it HEADER center was creating problems
-with long doc titles, esp. with PRINTSTYLE TYPEWRITE (which is when
-COPYSTYLE DRAFT is most likely to be used).
-
-***FIXES***
-No more "can't break line" warnings in DOCTYPE LETTER.
-
-If no REVISION number is given, Rev. 0 no longer appears HEADER_CENTER
-in COPYSTYLE DRAFT
-
-PAGENUM_STYLE now works as advertised.
-
-Release 1.1.1
--------------
-
-***CHANGES***
-Main macro file renamed to om.tmac, in keeping with current groff
-policy.
-
-Now okay to use groff mailing list for mom-related posts
-
-***NEW***
-Toggle macro -- BR_AT_LINE_KERN.  When on, automatically deposits
-a break whenever .RW or .EW are invoked.  Very useful when kerning
-whole lines of rag copy.
-
-***NEW***
-Toggle macro -- PAGENUM_ON_FIRST_PAGE.  Normally, when FOOTERS are
-being used instead of HEADERS, mom doesn't print the page number at
-the top of the first page of a doc, or the first page of collated docs.
-PAGENUM_ON_FIRST_PAGE allows user to get mom to put the page number on
-"first" pages if that's desired.
-
-***NEW***
-Macro -- BREAK_QUOTE -- to deal with problem of footnoted quotes and
-blockquotes that cross a page or column.
-
-***NEW***
-New argument to AUTOLEAD -- FACTOR.  With FACTOR, you can, if you
-wish, enter a factor by which AUTOLEAD multiplies the point size when
-calculating lead automatically.
-
-Improvements
-------------
-
-PAPER now has a much larger selection of common paper sizes.
-
-\*[ALD], \*[RLD], \*[FP] and \*[BP] now accept increments of quarter
-points (expressed as decimal fractions).  \*[RLD1.75], for example,
-reverses 1-3/4 points up on the line.
-
-HEADER_SIZE now available to PRINTSTYLE TYPEWRITE.  This was necessary
-to deal with the problem of excessively long HEADER_LEFT, _CENTER or
-_RIGHT strings.
-
-Fixes
------
-
-T_MARGIN -- can be set before or after LS or AUTOLEAD
-SS       -- remains constant regardless of WS
-WS       -- no longer affects SS
-TI       -- now works as expected even when called while another indent
-            type is in effect
-COLLATE  -- small fixes
-
-Broken .RW and .EW fixed.
-
-String tabs now behave properly when set from within tabs.
-
-UNDERLINE_QUOTES (for PRINTSTYLE TYPEWRITE) are now, in fact, on by
-default as the docs state.

-The files in this directory show mom in action.
-
-If you have downloaded and untarrred a version of mom from her
-homepage, you'll see that none of the example files come with
-corresponding PostScript (.ps) files, as they do with pre-compiled
-versions of groff, or groff built from source.
-
-I haven't included the PostScript output because I want to
-keep the mom archive as lean as possible.  To view the PostScript
-output, process the files with groff and either
-
-    a) send the output to a separate file for previewing with a
-       PostScript viewer such as gv (ghostview), or
-
-    b) to your printer.
-
-Using the file sample_docs.mom as an example, you would
-accomplish a) like this:
-
-    groff -mom -Tps sample_docs.mom > sample_docs.ps
-    gv sample_docs.ps
-
-Accomplishing b) depends on your printer setup, but a fairly
-standard way to do it would be
-
-    groff -mom -Tps sample_docs.mom | lpr
-
-                  or
-
-    groff -mom -Tps -l sample_docs.mom
-
-Note: I don't recommend previewing with gxditview because it doesn't
-render some of mom's effects properly.
-
-The files themselves
---------------------
-
-All are set up for 8.5x11 inch paper (US letter).
-
-***typesetting.mom**
-
-The file, typesetting.mom, demonstrates the use of typesetting tabs,
-string tabs, line padding, multi-columns and various indent styles,
-as well as some of the refinements and fine-tuning available via
-macros and inline escapes.
-
-Because the file also demonstrates a "cutaround" using a small
-picture (of everybody's favourite mascot, Tux), the PostScript file,
-penguin.ps has been included in the directory.
-
-***sample_docs.mom***
-
-The file, sample_docs.mom, shows examples of three of the document
-styles available with the mom's document processing macros, as well
-as demonstrating the use of COLLATE.
-
-The PRINTSTYLE of this file is TYPESET, to give you an idea of mom's
-default behaviour when typesetting a document.
-
-The last sample, set in 2 columns, shows off mom's flexibility
-when it comes to designing documents.
-
-If you'd like to see how mom handles exactly the same file when the
-PRINTSTYLE is TYPEWRITE (i.e. typewritten, double-spaced), simply
-change
-
-    .PRINTSTYLE TYPESET
-
-to
-
-    .PRINTSTYLE TYPEWRITE
-
-near the top of the file. 
-
-***letter.mom***
-
-This is just the tutorial example from the momdocs, ready for
-previewing.
-
-***elvis_syntax.new***
-
-For those who use the vi clone, elvis, you can paste this file into
-your elvis.syn.  Provided your mom documents have the extension
-.mom, they'll come out with colorized syntax highlighting.  The
-rules in elvis_syntax aren't exhaustive, but they go a LONG way to
-making mom files more readable.
-
-The file elvis_syntax (for pre-2.2h versions of elvis) is no longer
-being maintained.  Users are encouraged to update to elvis 2.2h or
-higher, and to use elvis_syntax.new for mom highlighting.
-
-I'll be very happy if someone decides to send me syntax highlighting
-rules for emacs. :)
-
-***mom.vim***
-
-Christian V. J. Brüssow has kindly contributed a set of mom syntax
-highlighting rules for use with vim.  Copy the file to your
-~/.vim/syntax directory, then, if your vim isn't already set up to
-do so, enable mom syntax highlighting with
-
-    :syntax enable
-
-or
-
-    :syntax on
-
-Please note: I don't use vim, so I won't be making changes to this
-file myself.  Christian Brüssow is the maintainer of the ruleset,
-which is available on the Web at
-
-    http://www.cvjb.de/comp/vim/mom.vim
-
-Contact Christian (cvjb@cvjb.de) if you have any suggestions or
-requests.

-.GREETING
-Dear Mr. Barrières,
-.PP
-It has come to my attention that you have been lobbying the
-US government to prohibit the use of open source software by
-endeavouring to outlaw so-called "warranty free" applications.
-.PP
-I feel it is my duty to inform you that the success of your
-operating system with its embedded web browser relies heavily
-on open source programs and protocols, most notably TCP/IP.
-.PP
-Therefore, in the interests of your corporation's fiscal health,
-I strongly advise that you withdraw support for any US
-legislation that would cripple or render illegal open source
-development.
-.CLOSING
-Sincerely,

-\# This file contains three greeked documents collated together:
-\#
-\#   i) two pages of a novelist's outline
-\#  ii) two pages of a chapter using COPYSTYLE DRAFT
-\# iii) three pages of an academic paper, set in two columns
-\#
-\# Mom's defaults are used throughout, except for iii), which
-\# demonstrates some of the ways you can design your own documents.
-\#
-\# Since the text throughout is greeked, and groff doesn't know how
-\# to hyphenate all that pseudo-latinate nonsense, I've inserted
-\# discretionary hyphens (\%) into a large number of the the words.
-\# Normally, this isn't necessary.
-\#
-\# The PRINTSTYLE is TYPESET.  If you'd like to see what mom does
-\# with the documents when the PRINTSTYLE is TYPEWRITE, change
-\# PRINTSTYLE TYPESET, below, to PRINTSTYLE TYPEWRITE.  Also, in the
-\# third example, comment out PARA_INDENT and QUOTE_INDENT (lines
-\# 332 and 333).
-\#
-\# ===================================================================
-\#
-\# First, a sample "NAMED" document--in this case, an outline.
-\# A novelist wouldn't normally write an outline with numbered heads,
-\# subheads and paraheads.  I've turned the feature on merely to

-\# Please notice, too, the use of "\&" before "..."  Whenever an

-.SH DESCRIPTION
-.
-.B mom
-(\[lq]my own macros\[rq], \[lq]my other macros\[rq], \[lq]maximum
-overdrive macros\[rq], .\|.\|.\&) is a macro set for groff, designed
-primarily to format documents for PostScript output.
-.PP
-.B mom
-provides two categories of macros: macros for typesetting and macros
-for document processing.
-The typesetting macros provide access to groff's typesetting power in
-ways that are simpler to master and to use than groff's primitives.
-The document processing macros provide customizable markup
-\[lq]tags\[rq] that allow the user to design and output
-professional-looking documents with a minimum of typesetting
-intervention.
-.PP
-mom comes with her own (very) complete documentation in HTML format.

-    <h2><u>Further notes on this documentation</u></h2>
-</a>
-
-Some <strong>mom</strong> users are sure to ask: &quot;Why is this
-documentation in html?  If <strong>mom</strong>'s so great, why not
-typeset the whole thing to show her off?  And if groff's so great,
-why not write a man page?&quot;
-<p>
-Valid questions, to be sure, and <strong>mom</strong> has
-answers.  (Okay -- I have answers, but I speak for
-<strong>mom</strong>.)
-<p>
-The documentation is in html because I still find it the best tool
-for navigating lengthy manuals.  Html, with its anchors and links,
-came into being precisely so people could do something they'd never
-been able to with the printed word: instantly track down internal
-and external references in a document.
-<p>
-To me, it's essential that people reading <strong>mom</strong>'s
-documentation never have difficulty finding precisely the macro
-they need for a particular task.  Equally, when reading up on
-a macro, they should never be presented with terms or other
-macro names for which they cannot instantly find accurate explanations.
-Short of having written the documentation in TeX for the info browser
-(and TeX bloat is one of the reasons I prefer to typeset with groff),
-I can think of no better way to achieve the kind of truly useful
-documentation I wanted than html.
-<p>
-Another reason for html is that working with <strong>mom</strong>
-necessarily involves creating files inside a text editor.  I use
-elvis, a truly fabulous vi clone that does a terrific job of rendering
-basic (text only) html.  I may have written <strong>mom</strong>,
-but I still regularly call on her documentation.  Elvis, with its
-html capabilities, lets me write and format <strong>mom</strong>
-documents AND peruse her documentation, clicking on links as
-necessary, without ever leaving the comfy confines of my
-text editor.
-<p>
-Not everyone, of course, uses an editor with html capabilities.
-For them, firing up a browser is obviously necessary for reading
-<strong>mom</strong>'s documentation.  Browsers being what they are,
-and not everyone on the globe having the cash for muscle machines
-to run Galeon, or Konqueror or Mozilla, their browser
-needs to be fast and light--and probably &quot;text-only&quot;.
-<p>
-Some <strong>mom</strong> users may notice the absence of graphics,
-frames, and (for the most part) tables in this documentation.  The
-reason is simple: text-only browsers.  People who, for whatever
-reason (choice or necessity), use lynx, or links or w3m to read
-the documentation must be able to make sense of it.  All of it.
-Graphical examples of <strong>mom</strong> in action might have made
-some parts of the documentation easier to write, but would have
-excluded text-only browser users.  And it goes without saying that
-the documentation looks fine if you're reading it in a graphical
-browser.

-<a name="FONTS">
-    <h2><u>Adding PostScript fonts to groff</u></h2>
-</a>
-
-<a name="SMALL_NOTE"></a>
-<em><strong>Small note:</strong> the term &lt;prefix&gt; in this
-section refers to the directory in which groff is installed,
-typically something like /usr/share/groff/&lt;version#&gt;
-(for distro-specific, pre-compiled groff packages) or
-/usr/local/share/groff/&lt;version#&gt; (if you've built groff
-from source).</em>
-<p>
-Groff comes with a small library of PostScript
-<a href="definitions.html#TERMS_FAMILY">families</a>
-(see the
-<a href="typesetting.html#FAMILY">FAMILY</a>
-macro for a list).  The families have four
-<a href="definitions.html#TERMS_FONT">fonts</a>
-associated with them.  These fonts are a combination of
-<a href="definitions.html#TERMS_WEIGHT">weight</a>
-and
-<a href="definitions.html#TERMS_SHAPE">shape</a>:
-<br>
-<ul>
-	<li><strong>R</strong> (Roman, usually Medium weight),
-	<li><strong>I</strong> (Italic, usually Medium weight),
-	<li><strong>B</strong> (Bold, usually Roman shape) and
-	<li><strong>BI</strong> (Bold Italic).
-</ul>
-<p>
-If you do a lot of document processing or typesetting with
-<strong>mom</strong>, you'll find, sooner or later, that these
-families and their associated fonts aren't sufficient.  You'll want
-to supplement them, either with more fonts for the families already
-provided--"Damn!  I need Helvetica Bold Condensed Italic!"--or with
-entire new families.
-<p>
-Without going into the gory details (yet), while it's true that
-adding fonts to groff is a relatively straightforward
-process, extending existing families or adding new ones requires
-some planning.
-<p>
-The traditional approach to extending groff families has been
-to create new families for non-default weights and
-shapes (e.g.  Light, which is a weight; Condensed, which is a
-shape), then to associate them with groff's predefined <strong>R,
-I, B</strong> and <strong>BI</strong> font styles.  An example
-of this can be seen in the groff PostScript font library itself
-(&lt;prefix&gt;/font/devps/): there's one &quot;family&quot; for
-Helvetica (HR, HI, HB, HBI) and another for Helvetica Narrow (HNR,
-HNI, HNB, HNBI).
-<p>
-The difficulty with this approach is that typographers
-tend to think of &quot;families&quot; as referring to the
-entire set of font weights and shapes associated with a
-particular family name.  For example, when a typesetter says
-&quot;the Helvetica family&quot;, s/he is including the <a
-href="definitions.html#TERMS_WEIGHT">weights</a> Helvetica Thin,
-Helvetic Light, Helvetica Regular, Helvetica Bold, Helvetica Heavy,
-etc, and all their associated
-<a href="definitions.html#TERMS_SHAPE">shapes</a>
-(Roman,
-Italic, Condensed, Narrow, Extended, Outline, etc).
-<p>
-Thus, intuitively, when a typesetter gives <strong>mom</strong> a
-<kbd>.FAM(ILY)</kbd> directive, s/he reasonably expects that any
-subsequent <kbd>.FT</kbd> directive will access the desired font
-from the Helvetica family--without the need to state explicitly both
-family and font to <kbd>.FT</kbd>, as it is explained one can do in
-the
-<a href="typesetting.html#FAMILY">FAMILY</a>
-and
-<a href="typesetting.html#FONT">FT</a>
-sections of these documents.
-<p>
-If one had, say, the fonts, Helvetica Light Roman
-and Helvetica Light Italic as well as Helvetica Light Condensed
-Roman and Helvetica Light Condensed Italic, the traditional
-approach would require two &quot;partial&quot; families: HLR/HLI and
-HLCDR/HLCDI.  Accessing these family/font combos
-routinely throughout a document would then require
-changing family (with <kbd>.FAM(ILY)</kbd>) and selecting the
-desired font (with <kbd>.FT R</kbd> or <kbd>.FT I</kbd>), or
-passing <kbd>.FT</kbd> the lengthy family+fontname (.e.g. <kbd>.FT
-HLCDI</kbd>).
-<p>
-Fortunately, groff provides a mechanism whereby it's possible to
-extend the basic <strong>R, I, B</strong> and <strong>BI</strong>
-fonts (&quot;styles&quot; in groff-speak) so that one can, in
-fact, create extensive type families, and access all the fonts
-in them with <kbd>.ft</kbd> (groff) or <kbd>.FT</kbd> (mom).
-<p>
-<strong>mom</strong> uses this mechanism to offer, in addition to
-groff's default PostScript font styles, the following:
-<p>
-<a name="STYLE_EXTENSIONS"></a>
-<pre>
-Mom's extensions to groff's basic font styles
-=============================================
-
-	L      =  Light Roman
-	LI     =  Light Italic
-	LCD    =  Light Condensed Roman
-	LCDI   =  Light Condensed Italic
-	LEX    =  Light Extended Roman
-	LEXI   =  Light Extended Italic
-	CD     =  Medium/Book Condensed Roman
-	CDI    =  Medium/Book Condensed Italic
-	EX     =  Medium/Book Extended Roman
-	EXI    =  Medium/Book Extended Italic
-	DB     =  DemiBold Roman
-	DBI    =  DemiBold Italic
-	BCD    =  Bold Condensed Roman
-	BCDI   =  Bold Condensed Italic
-	BEX    =  Bold Extended Roman
-	BEXI   =  Bold Extended Italic
-	HV     =  Heavy Roman
-	HVI    =  Heavy Italic
-	HVCD   =  Heavy Condensed Roman
-	HVCDI  =  Heavy Condensed Italic
-	HVEX   =  Heavy Extended Roman
-	HVEXI  =  Heavy Extended Italic
-	BL     =  Black Roman
-	BLI    =  Black Italic
-	BLCD   =  Black Condensed Roman
-	BLCDI  =  Black Condensed Italic
-	BLEX   =  Black Extended Roman
-	BLEXI  =  Black Extended Italic
-	UBL    =  Ultra-Black Roman
-	UBLI   =  Ultra-Black Italic
-</pre>
-
-Thus, with <strong>mom</strong>, if you've installed, say, some
-extra Helvetica fonts and named them according to the convention FS
-(where &quot;F&quot; means family and &quot;S&quot; means font
-style), once having entered
-<p>
-<pre>
-	.FAMILY H
-	  or
-	.FAM H
-</pre>
-
-you can access any of those Helvetica fonts simply by
-passing the correct argument from the list above to
-<a href="typesetting.html#FONT">FT</a>.
-<p>
-For example, if you were working in Medium Roman (<kbd>.FT R</kbd>)
-and you needed Medium Condensed Italic for a while (assuming it's
-installed), you'd just type
-<p>
-<pre>
-	.FT CDI
-</pre>
-
-to access the Medium Condensed Italic font from the Helvetica
-family.
-<p>
-<strong>Mom</strong>'s list of font styles doesn't pretend to
-be exhaustive, but rather tries to cover the basic weight/shape
-combinations likely to be found in any reasonably complete type
-family.
-<p>
-The actual extension names are arbitrary and can be used in a
-flexible manner.  For example, if you create a family that has a
-DemiBold font (DB) but no Bold font (B), you might find it more
-convenient to give the DemiBold font the extension &quot;B&quot;.
-Equally, if the family has an ExtraBold font, you might find it more
-convenient to use the extension &quot;HV&quot; (Heavy).
-<a name="REGISTER_STYLE"></a>
-<p>
-However, you may, at needs, want to add to <strong>mom</strong>'s
-list of font styles.  You can do this by editing the file, om.tmac.
-Near the top, you'll see lines of the form
-<p>
-<pre>
-	.sty \n[.fp] L       \" Light Roman
-	.sty \n[.fp] LI      \" Light Italic
-	.sty \n[.fp] LCD     \" Light Condensed Roman
-</pre>
-
-Simply add your new font style by imitating what you see and
-plugging in your new font style (having, of course, first created the
-font, correctly named, in groff's PostScript font directory; see
-<a href="#HOWTO">How to create a PostScript font for use with groff</a>).
-<p>
-For example, if you already have some fonts from the Univers
-family installed and have called the family UN, you might decide at
-some point to add the Bold Outline font (UNBO).  In which case,
-you'd add
-<p>
-<pre>
-	.sty \n[.fp] BO      \" Bold Outline
-</pre>
-
-to the <kbd>.sty \n[.fp] &lt;font style&gt;</kbd> list in om.tmac.
-<p>
-Be careful, though, that any styles you add do not conflict
-with <strong><u>family</u></strong> names that already exist.
-&quot;C&quot;, for example, conflicts with the Courier family
-(CR, CI, CB, CI).  Were you to create a font style &quot;C&quot;,
-thinking that <kbd>.FT C</kbd> would give you access to font style
-once you'd given a <kbd>.FAM(ILY)</kbd> directive, you'd get a nasty
-surprise: your type would come out in Courier Roman!
-<p>
-<strong>VERY IMPORTANT NOTE: mom</strong>'s font extensions are
-not &quot;user-space&quot; controllable via a macro.  If you've
-been using groff for a long time, and have already rolled your own
-solution to adding PostScript families, fonts, weights, shapes, etc. to
-groff, you may find that <strong>mom</strong>'s font extensions
-conflict with your own scheme.  Should that be the case, comment out
-the <kbd>.sty \n[.fp] &lt;font style&gt;</kbd> lines found near the
-top of the om.tmac file.
-
-<a name="HOWTO"><h3><u>How to create a PostScript font for use with groff</u></h3></a>
-These instructions aren't meant to cover all possibilities, merely
-to present one way of making PostScript families/fonts available to
-groff and <strong>mom</strong>.
-<p>
-GNU/Linux distributions being what they are, directory locations may
-differ and the presence of some executables can't be guaranteed.
-I run a Debian system.  The instructions reflect that.  Users of
-other distros will have to interpret them according to the way their
-distro operates.
-<p>
-What you need before you start:
-<br>
-<ul>
-	<li>groff, version 1.18 or higher
-		<br>
-		(Debian package: groff)
-	<li>a full installation of gs and associated tools
-		<br>
-		(Debian package: gs or gs-gpl)
-	<li>a library of gs fonts
-		<br>
-		(Debian package: gsfonts)
-	<li>a utility for converting TrueType fonts to Type1 fonts
-		<br>
-		(Debian package: ttf2pt1)
-	<li>a font manager
-		<br>
-		(Debian packages: defoma, psfontmgr, dfontmgr)
-	<li>perl
-		<br>
-		(Debian package: perl)
-</ul>
-<br>
-A reasonably complete installation of any major GNU/Linux distro
-should already have these on your system, except perhaps for the
-utility to convert TrueType fonts to Type1 fonts.
-<p>
-Initial preparation (you only have to do this once):
-<br>
-<ol>
-	<li>If you don't already have one, create a directory in your
-		home directory to hold new fonts.  Any directory name will do.
-		I use ~/Fonts, with subdirectories for Type1, TrueType and Groff
-		fonts.
-<a name="SITE-FONT"></a>
-	<li>Locate the groff directory, site-font.  The exact location is
-		difficult to predict, owing to differences between distros
-		and whether you're using a pre-packaged groff or have built
-		it from source.  Some typical locations are
-		<br>
-		<ul>
-			<li>/usr/share/groff,
-			<li>/usr/local/share/groff
-			<li>/etc/groff
-		</ul>
-		<p>
-		If you can't find the site-font directory, locate
-		groff's site-tmac directory, and, as root, create site-font
-		in the same directory as the one that holds site-tmac.
-		E.g., if you find site-tmac in /usr/share/groff, create
-		site-font in /usr/share/groff.
-	<li>Locate the file <kbd>&lt;prefix&gt;/font/devps/generate/textmap</kbd>
-        and symlink it to <kbd>textmap</kbd> in the directory that
-        contains your personal collection of PostScript fonts.  (See the
-		<a href="#SMALL_NOTE">Small Note</a>,
-		above, for the meaning of &lt;prefix&gt;).  On my system,
-		at the time of writing, &lt;prefix&gt; is
-		/usr/local/share/groff/1.19.2/, therefore, I symlink it in
-		~/Fonts/Type1 with
-		<br>
-		<pre>
-ln -s /usr/local/share/groff/1.19.2/font/devps/generate/textmap textmap
-		</pre>
-	<li>Locate the file &lt;prefix&gt;/font/devps/text.enc and
-		symlink it to <kbd>text.enc</kbd> in your personal font
-		directory.  On my system, in ~/Fonts/Type1
-		<pre>
-ln -s /usr/local/share/groff/1.19.2/font/devps/text.enc text.enc
-		</pre>
-	<li>Make sure you know which directory/ies holds your gs fonts.
-		You'll need the information later.  On a Debian box, some
-		typical locations are
-		<br>
-		<ul>
-			<li>/usr/lib/ghostscript/fonts
-			<li>/usr/share/ghostscript/fonts
-			<li>/usr/share/fonts/type1/gsfonts
-		</ul>
-</ol>
-<br>
-Font creation/installation:
-<br>
-<ol>
-	<li>Acquire the font in either Type1 (.pfb) or TrueType
-		(.ttf) format.
-	<li>Place the font in your personal font directory; for me,
-		that's ~/Fonts/Type1 or ~/Fonts/TrueType.
-	<li>In your personal font directory, run one of the following:
-		<br>
-		<ul>
-			<li>For Type1 fonts
-			<br>
-			<ul>
-				<li><kbd>getafm fontfilename.pfb | gsnd - > fontfilename.afm</kbd>
-					<br>
-					For Type1 fonts, this will generate something called
-					an .afm (Adobe Font Metrics) file, which is
-					required to create PostScript fonts for groff.
-			</ul>
-			<li>For TrueType fonts
-			<br>
-			<ul>
-				<li><kbd>ttf2pt1 \-b fontfilename.ttf</kbd>
-				<br>
-				For TrueType fonts, this will generate a PostScript
-				.pfb file as well as an .afm file.
-			</ul>
-		</ul>
-	<li>Still in your personal font directory, run
-		<br>
-		<ul>
-			<li><kbd>afmtodit -e text.enc fontfilename.afm textmap GROFF_FONTNAME</kbd>
-		</ul>
-		<p>
-		Q: <em>How do I choose a GROFF_FONTNAME?</em>
-		<p>
-		A: Start by considering the
-		<a href="definitions.html#TERMS_FAMILY">family</a>
-		to which the font belongs.  If you're adding to a family that
-		already exists in groff's &lt;prefix&gt;/font/devps
-		directory, that will be the first part of the font name.
-		(See
-		<a href="typesetting.html#FAMILY">here</a>
-		for a list of families already installed, along with their groff
-		names.)  Add to that name the appropriate weight/style extension,
-		listed
-		<a href="#STYLE_EXTENSIONS">here</a>.
-		<p>
-		For example, if you're adding Helvetica Light Roman, your
-		GROFF_FONTNAME would be <strong>HL</strong>.  If you're
-		adding Helvetica Light Italic, your GROFF_FONTNAME would be
-		<strong>HLI</strong>.
-		<p>
-		If you're adding a font not already in groff's PostScript
-		families, first choose a meaningful name for the
-		<a name="definitions.html#TERMS_FAMILY">family</a>
-		to which the font belongs.  The name can be anything you like.  If,
-		for example, the family is Garamond, you could choose GARAMOND,
-		GARA, GD, or even just plain G as the family name.  Then tack on the
-		appropriate style/weight extension.  Thus, if you were installing
-		Garamond Bold Condensed Italic and had chosen <strong>GD</strong>
-		as the family name for Garamond, your GROFF_FONTNAME would be
-		<strong>GDBCDI</strong>.
-		<p>
-		In <strong>mom</strong>, you can then access the Garamond
-		family with <kbd>.FAM GD</kbd>, and the Bold Condensed
-		Italic font wth <kbd>.FT BCDI</kbd>.
-		<p>
-		<strong>Note:</strong> The family name need not be in upper
-		case, and there's no limit to the length of the name.
-		&quot;Garamond&quot;, for example, could be the name you
-		give the Garamond family.  In fact, you might find it
-		preferable, since a) you wouldn't have to remember how
-		you'd named the family, and b) should you be scanning
-		your
-		<a href="#SITE-FONT">site-font directory</a>,
-		something like GaramondBCDI will be more meaningful than,
-		say, GDBCDI. 
-	<li>Copy or move GROFF_FONTNAME to your
-		<a href="#SITE-FONT">site-font directory</a>,
-		or change to the site-font directory and make a symlink to
-		GROFF_FONTNAME in your personal directory.
-	<li>Copy or move the .pfb file to the directory that
-		holds your gs fonts, or change to that directory and make a
-		symlink to the .pfb file in your personal directory.
-	<li>Do whatever your system or distro requires in order to
-		register the new PostScript font (the .pfb file).  On a
-		Debian system, as root, you can run dfontmgr for a
-		graphical interface that will take care of registering the
-		font.
-</ol>
-<p>
-Written out in full, adding fonts looks like a lot of work.  It
-isn't.  Basically, it's just:
-<br>
-<ul>
-	<li>acquire the font
-	<li>generate an .afm file for the font
-	<li>create the groff font
-	<li>put the groff font in &lt;prefix&gt;/font/devps
-	<li>make sure gs knows about the font
-</ul>
-<br>
-After you've done it a couple of times, it all makes sense, and is
-really quite easy.  Not to mention that once you understand the
-process, you can write a bash script to automate the process.
-Here's an example, which you can adapt to your own needs.  The
-script requires an argument (the .pfb filename), then prompts for
-the GROFF_FONTNAME.
-<p>
-<pre>
-#! /bin/bash
-
-# A script for installing Type1 fonts.
-#
-# Builds .afm files from .pfb files, generates a groff font from the
-# .afm file, makes a symlink in /usr/lib/ghostscript/font/ to the
-# .pfb file, and a symlink in site-font to the groff font
-
-# .pfb filename, stripped of .pfb extension
-FONT=`basename $1 .pfb`
-
-# Directory holding my personal collection of type1 fonts
-FONTDIR="$HOME/Fonts/Type1"
-
-# Directory holding system ghostscript fonts
-GS_FONTDIR="/usr/lib/ghostscript/fonts"
-
-# Location of site-font/devps
-GROFF_SITE_FONTDIR="/usr/local/share/groff/site-font/devps"
-
-# Personal groff fonts directory
-GROFF_FONTS="$HOME/Fonts/Groff"
-
-# Symlinks to textmap and text.enc
-TEXTMAP="$FONTDIR/textmap"
-TEXTENC="$FONTDIR/text.enc"
-
-if [ ! `pwd` = "$FONTDIR" ] ; then
-    echo "Changing into $FONTDIR directory.."
-    cd $FONTDIR
-    sleep 1
-else
-	sleep 1
-fi
-
-echo -n "Groff name for this font: "
-read FONTNAME
-sleep 1
-
-echo "Getting .afm.."
-getafm $FONT.pfb | gsnd - > $FONT.afm
-sleep 1

-	<h2><u>Some reflections on mom</u></h2>
-</a>
-
-<p>
-<strong>Mom</strong>, as a complete macro set, had her origins
-in a &quot;library&quot; of groff routines I wrote over the
-years to handle various aspects of typesetting and document
-processing that weren't adequately covered by ms, me, mm, and so
-on.  Typically, I'd use the library to cobble together macro
-sets for new challenges as they came my way.
-<p>
-If, as Eric Raymond asserts, open source begins with a programmer
-scratching a personal itch, then <strong>mom</strong> can truly be
-called open source, even if, a mere humble set of macros standing on
-the shoulders of a giant named troff, she isn't programming at all.
-<p>
-As a writer living in a perpetual state of penury, all the computers
-I've ever owned have been hand-me-downs -- several generations
-out-of-date and &quot;resource challenged&quot;.  Disk space has
-always been an issue, as has processor speed and available RAM.
-One of the reasons I run GNU/Linux is that it has helped enormously
-to get the most out of my poor little boxes.  (It has been pointed
-out to me that NetBSD might be an even better choice of operating
-systems for computers with limited resources.)
-<p>
-In Linux-land, the choice of typesetting systems basically comes down
-to groff or TeX.  Both are wonderful -- monumental achievements if you
-ask me -- and both have their own particular strengths.  However, for
-people in my financial position (and there are millions of us around
-the globe, in both developed and developing countries), TeX and groff
-have one big difference: size.  TeX is huge.  Even its most ardent
-supporters agree it suffers from bloat, on top of being complex and
-unwieldy to manage.  Groff is tiny by comparison, occupying minimal
-disk space and having only a small memory footprint while at the same
-time being flexible and powerful, typographically speaking.  I've run
-it successfully on a 386 with 8 megs of RAM and a 250 meg hard disk.
-<p>
-However, groff has always had a liability: it's incredibly geeky.
-Owing to its very long history, it -- and its &quot;power users&quot;
--- have remained stuck in a time warp.  Most common macro packages
-still look as they did in those decades when memory was exorbitantly
-expensive and every byte mattered.  Documentation -- not always
-easy to find -- is written as if all readers are computer whizzes,
-or at least have a university degree in one of the higher sciences.
-<p>
-By no means a stupid man, nor unfamiliar with the precepts of
-programming, I've more than once torn my hair out over the terseness and
-ambiguity of groff's documentation.  Making sense of certain primitives
-has often involved days of testing, interpreting the documentation
-instead of just using the primitive.
-<p>
-(ADDENDUM to the previous two paragraphs:  A tremendous amount of
-effort has gone into creating a groff manual that can be read with
-"info," as well as creating truly useful man pages.  The info
-manual is clear and well-written, so my comments are actually out
-of date.  I leave them in for the benefit of groff newbies, who may
-still find the documents a bit intimidating.)
-<p>
-For some time now, groff users and macro writers have had the
-option to use &quot;long&quot; names, yet have mostly chosen not to.
-With long names, it's possible to create macro sets that are humanly
-readable and easy to interpret, encouraging development and evolution.
-What's more, the macros themselves need not be terse, intimidating,
-and easily forgotten 1- or 2-letter commands inserted in the body
-of a document.  They can be sensible and helpful to everyone, groff
-newbies and old hands alike.
-<p>
-<strong>Mom</strong>'s macro file, om.tmac, uses long names, aliases,
-and a host of other groff goodies that have become part of the
-whole groff picture under the unflagging guidance of groff's current
-maintainer, Werner Lemberg.  Nearly every macro, number register and
-string is &quot;recognizable&quot; simply by its name.  The file is
-heavily commented.  A consistent, if idiosyncratic, indenting style
-is used as well, significantly improving readability.  Anyone
-wanting to futz around with <strong>mom</strong>'s macros should be
-able to do so with a minimum of head scratching.

-	<h2><u>Introduction to coloured text</u></h2>
-</a>
-
-<strong>Mom</strong>'s support for coloured text is straightforward.
-You begin by telling <strong>mom</strong> about the colours you want
-with
-<a href="#NEWCOLOR">NEWCOLOR</a>
-or
-<a href="#XCOLOR">XCOLOR</a>.
-Afterward, any time you want text to be coloured, you either colour
-it with an
-<a href="definitions.html#TERMS_INLINES">inline escape</a>
-that contains the colour name (e.g. <kbd>\*[red]</kbd> or
-<kbd>\*[blue]</kbd>) or invoke the macro,
-<a href="#COLOR">COLOR</a>,
-with the name of the colour you want.
-<a name="COLOR_EXAMPLE"></a>
-<p>
-For example, say you want to have the name &quot;Jack&quot; in the
-sentence &quot;All work and no play makes Jack a dull boy&quot;
-appear in yellow.  You'd begin by telling <strong>mom</strong> about
-the colour, yellow.  There are two ways of doing this; see
-<a href="#NEWCOLOR">NEWCOLOR</a>
-and
-<a href="#XCOLOR">XCOLOR</a>
-for a full explanation of the difference between the two.  If you
-use <strong>XCOLOR</strong>, you'd enter this:
-<p>
-<pre>
-	.XCOLOR yellow
-</pre>
-
-If you use <strong>NEWCOLOR</strong>, you might enter
-<p>
-<pre>
-	.NEWCOLOR yellow RGB #FFFF00
-</pre>
-
-<a name="COLOR_EXAMPLE2"></a>
-After &quot;defining&quot; (or &quot;initializing&quot;) the colour
-&quot;yellow&quot;, you'd colourize the name, Jack, either with an
-inline escape
-<p>
-<pre>
-	All work and no play makes \*[yellow]Jack\*[black] a dull boy.
-</pre>
-
-or with the <strong>COLOR</strong> macro
-<p>
-<pre>
-	All work and no play makes
-	.COLOR yellow
-	Jack
-	.COLOR black
-	a dull boy.
-</pre>
-
-Notice, in both examples, that a) you have to set the colour back to
-black after &quot;Jack&quot;, and b) you don't have to define or
-intialize the colour, black.  <strong>Mom</strong> predefines
-&quot;black&quot;, &quot;BLACK&quot;, &quot;white&quot; and
-&quot;WHITE&quot; for you.
-<p>
-For information on using colour during
-<a href="docprocessing.html#INTRO_MACROS_DOCPROCESSING">document processing</a>,
-see
-<a href="docprocessing.html#COLOR">Colour support in document processing</a>.
-<p>
-<strong>Please note: Mom</strong>'s colour support is for text only.
-She doesn't support &quot;fill&quot; (or &quot;background&quot;)
-colour for drawn objects.  Please also note that if you're
-accustomed to using groff's <kbd>.defcolor</kbd> to define colours,
-and groff's inline <kbd>\m[&lt;colorname&gt;]</kbd> to call them, you may
-continue to do so without confusing <strong>mom</strong>.

-<br>
-<nobr>Macro: <strong>NEWCOLOR</strong> &lt;colour name&gt; [&lt;colour scheme&gt;] &lt;colour components&gt;</nobr>
-
-<p>
-<strong>NEWCOLOR</strong> lets you create a colour, rather like an
-artist mixing paint on a palette.  The colour isn't used
-immediately; <strong>NEWCOLOR</strong> merely tells
-<strong>mom</strong> how to mix the colour when you need it.  If
-you haven't invoked <strong>NEWCOLOR</strong> (or
-<a href="#XCOLOR">XCOLOR</a>),
-<strong>mom</strong> doesn't have a clue what you mean when you
-reference a colour (with 
-<a href="#COLOR">COLOR</a>
-or
-<a href="#COLOR_INLINE">\*[&lt;color name&gt;]</a>).
-<p>
-The first argument to <strong>NEWCOLOR</strong> is a name for your
-colour.  It can be anything you like--provided it's just one word
-long--and can be caps, lower case, or any combination of the two.
-<p>
-The second argument, which is entirely optional, is the &quot;colour
-scheme&quot; you want <strong>mom</strong> to use when mixing the
-colour.  Valid arguments are <strong>RGB</strong> (3 components,
-red green blue), <strong>CYM</strong> (3 components cyan yellow
-magenta), <strong>CMYK</strong> (4 components cyan magenta yellow
-black) or <strong>GRAY</strong> (1 component).  If you omit the
-second argument, <strong>mom</strong> assumes you want RGB.
-<p>
-The final argument is the components of your colour.  This can be
-hexadecimal string starting with a pound sign (#) (for colour values
-in the 0-255 range) or two pound signs (##) (for colour values
-in the 0-65535 range), or it can be a series of decimal digits,
-separated by spaces, one digit per component, with the argument
-enclosed in double quotes.  (If this is all gibberish to you, see
-<a href="#COLOR_TIP">Tips for newbies</a>.)
-<p>
-Thus, to tell <strong>mom</strong> about a colour named
-&quot;YELLOW&quot;, you could enter one of the following:
-<p>
-<pre>
-	.NEWCOLOR YELLOW #FFFF00         \"or ##FFFFFFFF0000 or "1 1 0"
-	.NEWCOLOR YELLOW RGB #FFFF00     \"or ##FFFFFFFF0000 or "1 1 0"
-	.NEWCOLOR YELLOW CYM #00FF00     \"or ##0000FFFF0000 or "0 1 0"
-	.NEWCOLOR YELLOW CYMK #00FF0000  \"or ##0000FFFF00000000 or "1 1 0"
-</pre>
-
-After you've told <strong>mom</strong> about a colour, you can then get
-her to set text in that colour either with the inline escape
-<a href="#COLOR_INLINE">\*[&lt;colorname&gt;]</a>
-or the macro
-<a href="#COLOR">COLOR</a>.
-(See the
-<a href="#COLOR_EXAMPLE">example</a>,
-above.)
-<br>
-<h3><u>Tips for newbies</u></h3>
-Colour manipulation can be tremendously confusing if you don't have
-a background in graphic arts or computing.  My advice, if color
-intimidates you, is to stick to using <strong>mom</strong>'s
-default RGB colour scheme, and to fire up a color chooser that
-gives you the RGB values you want for the colour you select.  Plug
-those values into the components argument to
-<strong>NEWCOLOR</strong>, and you'll get the colour you want.
-Both the KDE and gnome desktops have colour selectors that provide
-you with the shorter RGB hexadecimal string.  If you're not running
-KDE or gnome, the X utility, xcolorsel, provides you with a similar
-functionality, although it only provides RGB values for 256
-pre-defined colours.  If you use xcolorsel, be sure to click the
-button &quot;Display format&quot; and select &quot;8 bit truncated
-rgb&quot;.
-<p>
-Alternatively, you can use <strong>mom</strong>'s simpler
-<a href="#XCOLOR">XCOLOR</a>
-macro to initialize one of the 256 pre-defined X colours by
-supplying the name of the color as an argument.
-<br>
-
-<!---XCOLOR--->
-
-<hr width="33%" align="left">
-<a name="XCOLOR"><h3><u>Initializing a colour with XCOLOR</u></h3>
-<br>
-<nobr>Macro: <strong>XCOLOR</strong> &lt;X color name&gt; [&lt;alias&gt;]</nobr>
-<br>
-<em>*&lt;X color name&gt; must be all one word, all lower case.
-<br>
-(See
-<a href="#XCOLOR_NAMES">Finding X color names</a>
-for how to get a list of valid colour names.)
-</em>
-<p>
-<strong>XCOLOR</strong> is similar to <strong>NEWCOLOR</strong> in
-that it tells <strong>mom</strong> to initialize a colour, but it's
-easier to use.  All you have to do is pass it, as an argument, the
-legal name of one of the 256 pre-defined X colours.  The name must
-be all one word, and, breaking with <strong>mom</strong> policy, it
-must be entered in lower case.
-<p>
-For example, if you want to intialize the X colour, coral, all you
-have to do is enter
-<br>
-<pre>
-	.XCOLOR coral
-</pre>
-
-Afterwards
-<p>
-<pre>
-	.COLOR coral
-</pre>
-
-will colourize subsequent text coral until you instruct
-<strong>mom</strong> to return to black, or some other pre-defined
-initialized colour.  (The
-<a href="definitions.html#TERMS_INLINES">inline escape</a>
-<kbd>\*[coral]</kbd> will equally colourize text coral after you've
-initialized the colour with <strong>XCOLOR</strong>.)
-<p>
-The downside of <strong>XCOLOR</strong> is that you can't create
-custom colours.  This restriction, however, is mitigated by the
-fact that for many users, 256 colours is more than enough to play
-around with.
-<p>
-While some X colours have fanciful names (peachpuff, papayawhip,
-thistle, snow), many are self-explanatory and self-descriptive in
-ordinary colour terms.  &quot;blue&quot; is pure (rgb) blue,
-&quot;green&quot; is pure (rgb) green, and so on.  Furthermore, for
-many X colors, there exist four variants, each representing
-increasingly darker shades of the same colour.  For example,
-&quot;blue&quot; (and &quot;blue1&quot;) are the brightest forms of
-(rgb) blue; &quot;blue2&quot;, &quot;blue3&quot; and &quot;blue4&quot;
-are increasingly darker shades of the same blue.  For that reason,
-you may find <strong>XCOLOR</strong> is a better choice than
-<strong>NEWCOLOR</strong> when it comes to initializing common
-colors.
-<p>
-The whimsical nature of X colour names sometimes makes for names
-that are long to type in, e.g. &quot;mediumspringgreen&quot;.
-The optional second argument to <strong>XCOLOR</strong> allows you
-to come up with more convenient name by which to reference the
-colour.  For example, you could enter
-<p>
-<pre>
-	.XCOLOR mediumspringgreen mygreen
-	    or
-	.XCOLOR mediumspringgreen MYGREEN
-</pre>
-
-so that whenever you want text mediumspringgreen-ed, you can use
-either <kbd>.COLOR mygreen</kbd> (or <kbd>.COLOR MYGREEN</kbd>) or
-the inline escape <kbd>\*[mygreen]</kbd> (or
-<kbd>\*[MYGREEN]</kbd>.)
-<p>
-<a name="XCOLOR_NAMES"><h3><u>Finding X color names</u></h3></a>
-<br>
-There are two ways of finding the names of the pre-defined X
-colours.  One is to consult the file, rgb.txt, included with
-all X11 installations.  The location of the file on a Debian
-GNU/Linux distribution is typically /etc/X11/rgb.txt.  Other
-distributions and other X installations may have the file in
-another location.  The file lists the colour names, but doesn't
-show you what the colours actually look like.
-<p>
-A better way to get the colour names, as well as to see what the
-colours look like, is to fire up a colour chooser (like xcolorsel)
-that both lists the colour names and shows a swatch of the colour
-as well.
-<p>
-Whichever method you use to find X color names, remember that the
-names, passed as arguments to <strong>XCOLOR</strong>, <em>must</em>
-be all one word, all in lower case.

-<p>
-<a name="COLOR_INLINE"></a>
-Once you've told <strong>mom</strong> about a colour (via
-<strong>NEWCOLOR</strong> or <strong>XCOLOR</strong>), you use either
-the macro, <strong>COLOR</strong>, or the
-<a href="definitions.html#TERMS_INLINES">inline escape</a>,
-<kbd>\*[&lt;colorname&gt;]</kbd>, to cause <strong>mom</strong> to

-<p>
-<strong>NOTE:</strong> You can use the

-However, you must remember to reset the colour at the end of the

-<p>
-Furthermore, if you use <kbd>\*[&lt;colorname&gt;]</kbd> in the

-the numbers themselves will not be coloured, only the text you
-passed the macro.  If you wish the numbers to be colourized as
-well, you must explicitly tell <strong>mom</strong> that you wish
-all of the head(s), subhead(s) or parahead(s), including the
-numbers, colourized by invoking the appropriate

-<a name="COVER_INTRO"><h2><u>Introduction to cover pages</u></h2></a>
-<p>
-As of version 1.19 of <strong>mom</strong>, you can now have cover
-pages generated automatically.
-<p>
-Though identical in treatment, <strong>mom</strong> provides two
-kinds of cover pages: section cover pages (which I shall refer to
-simply as &quot;cover pages&quot;) and document cover pages
-(&quot;doc covers&quot;).
-<p>
-A document cover page
-(<a href="#DOC_COVER">doc cover</a>)
-is what you'd most likely use at the start of a <a
-href="rectoverso.html#COLLATE_INTRO">collated</a> document, where
-you might want the name of the complete document, the author(s) and
-the copyright line to appear.  Another place you might use a doc
-cover is for a novel, where you want the title of the novel, not
-the chapter title or chapter number, as the first cover page.
-<p>
-A section
-<a href="#COVER">cover</a>
-page is what you'd use for cover pages that separate sections of a
-collated document.  A section cover page (but not a doc cover page)
-in a collated document could, for example, simply read &quot;PART
-I&quot;.
-<p>
-In non-collated documents (say, an essay) you can use either a
-section cover or a doc cover to generate a cover sheet.
-<p>
-In addition, nothing prevents you from generating both a doc cover
-page and a section cover page for every document in a collated
-document.  Or you can selectively disable the automatic generation
-of either doc covers or section covers in a collated document,
-on-the-fly.
-<p>
-<a name="PLEASE"><strong>Important note:</strong></a>
-automatic generation of cover or doc cover pages after the first
-one(s) only takes place if you are working with collated documents.
-<strong>Mom</strong> provides no mechanism for saying &quot;print
-a section cover here even though I'm still working on the same
-(non-collated) document.&quot;
-
-<a name="DESC"><h3><u>Description of what mom does on cover pages</u></h3></a>
-
-By default, <strong>mom</strong> typesets cover (and doc cover)
-pages identically to
-<a href="definitions.html#TERMS_DOCHEADER">docheaders</a>
-(see
-<a href="docprocessing.html#DOCHEADER_CONTROL">How to change the look of docheaders</a>
-for a description of what a docheader looks like).  The only
-differences are
-<br>
-<ul>
-	<li>the position on the page where the information is output
-	<li>the (optional) addition of copyright and miscellaneous
-		information
-	<li>there's no running text underneath
-</ul>
-
-<p>
-You tell <strong>mom</strong> what you want to appear on the cover
-pages through the arguments you pass to
-<a href="#COVER">COVER</a>
-and/or
-<a href="#COVER">DOC_COVER</a>.
-Provided you have already given <strong>mom</strong> the
-appropriate references macro (e.g.
-<a href="docprocessing.html#TITLE">TITLE</a>
-or
-<a href="docprocessing.html#AUTHOR">AUTHOR</a>),
-she will output cover (and doc cover) pages identically to how she
-would output docheaders containing the same information.
-<p>
-By default, <strong>mom</strong> starts cover (and doc cover) pages
-one-third of the way down the page.  This can be changed through
-the use of the control macros
-<a href="#COVER_CONTROL_INDEX">COVER_ADVANCE/DOC_COVER_ADVANCE</a>.
-<p>
-If you request copyright information (and have already given
-<strong>mom</strong> the reference macro,
-<a href="docprocessing.html#COPYRIGHT">COPYRIGHT</a>),
-she sets it, by default, in a smaller
-<a href="definitions.html#TERMS_PS">point size</a>
-in the bottom right hand corner of the cover (or doc cover) page.
-The default point size and the position can be controlled
-with
-<a href="#COVER_CONTROL_INDEX">COVER_COPYRIGHT_SIZE/DOC_COVER_COPYRIGHT_SIZE</a>
-and
-<a href="#COVER_CONTROL_INDEX">COVER_COPYRIGHT_QUAD/DOC_COVER_COPYRIGHT_QUAD</a>.
-<p>
-Similarly, if you request miscellaneous information (and have already given
-<strong>mom</strong> the reference macro,
-<a href="docprocessing.html#MISC">MISC</a>),
-she sets it, by default, in a smaller point size in the bottom left
-hand corner of the cover (or doc cover) page.  The default point
-size is dependent on
-<strong>COVER_COPYRIGHT_SIZE/DOC_COVER_COPYRIGHT_SIZE</strong>,
-but the position can be controlled with
-<a href="#COVER_CONTROL_INDEX">COVER_MISC_QUAD/DOC_COVER_MISC_QUAD</a>.
-
-<a name="PAGINATION"></a>
-<p>
-<strong>NOTE: mom</strong> does not set any
-<a href="definitions.html#TERMS_HEADER">headers</a>
-or
-<a href="definitions.html#TERMS_FOOTER">footers</a>
-on cover pages.  Neither does she set any page numbers.  From the
-point of pagination, cover (and doc cover) pages are considered
-&quot;null&quot; pages; if you wish them to be included in the
-pagination scheme (even though no page numbers appear), you must
-set the page number of each first page following a
-<a href="rectoverso.html#COLLATE">COLLATE</a>
-manually with
-<a href="headfootpage.html#PAGENUMBER">PAGENUMBER</a>.
-
-<a name="DESIGN"></a>
-<p>
-Finally, if you want to design your own cover page(s), you can
-always typeset them (using the
-<a href="typesetting.html#MACROS_TYPESETTING">typesetting macros</a>),
-invoke
-<a href="typesetting.html#NEWPAGE">NEWPAGE</a>,
-set up your document <em>in full</em> (see
-<a href="docprocessing.html#DOCPROCESSING_TUT">Tutorial -- Setting up a mom document</a>),
-and lastly invoke
-<a href="docprocessing.html#START">START</a>.
-The cover page (and any typesetting commands on it) will have no
-effect on <strong>mom</strong>'s processing of the document itself,
-the first page of which, moreover, will be numbered &quot;1&quot;
-unless you instruct her otherwise with
-<a href="headfootpage.html#PAGENUMBER">PAGENUMBER</a>.

-	Macro: <strong>COVER</strong>
-	<br>
-	Macro: <strong>DOC_COVER</strong>
-	<br>
-	Required argument: <nobr>TITLE | DOCTITLE | COVERTITLE | CHAPTER | CHAPTER_TITLE | CHAPTER+TITLE</nobr>
-	<br>
-	Optional arguments: <nobr>[ SUBTITLE AUTHOR DOCTYPE COPYRIGHT MISC ]</nobr>
-	<p>
-	<em>*Note: these macros should be placed in the
-	&quot;style-sheet&quot; section of your document setup (see the
-	<a href="docprocessing.html#DOCPROCESSING_TUT">Tutorial -- Setting up a mom document</a>),
-	i.e. after PRINTSTYLE (and/or DOCTYPE and/or COPYSTYLE), but
-	before START.</em>
-
-</a>
-<p>
-<strong>COVER</strong> and <strong>DOC_COVER</strong> behave
-identically.  The reason <strong>mom</strong> provides two macros
-for automatic cover page generation is so that you can have two
-different kinds of covers with different information on each.
-<p>
-Imagine, for a moment, you've written a document comprised of three
-sections.  When you
-<a href="rectoverso.html#COLLATE">COLLATE</a>
-the document for output, you could use <strong>DOC_COVER</strong>
-to generate a cover page that contained the name of the entire
-document, your (the author's) name, and perhaps the copyright date.
-Subsequently, you could use <strong>COVER</strong>, after each
-<strong>COLLATE</strong> but before each
-<a href="docprocessing.html#START">START</a>,
-to generate a cover page (or cover &quot;sheet&quot;, if you prefer)
-containing just the name of the section.
-<br>
-
-<a name="REQUIRED"><h3><u>The required argument</u></h3></a>
-
-Both <strong>COVER</strong> and <strong>DOC_COVER</strong>, whenever
-invoked, require a first argument, as listed above.  This first argument
-will become the first bit of information <strong>mom</strong>
-prints on the cover (or doc cover) page (i.e. it will be the
-&quot;title&quot;).
-<p>
-In order for the information to appear, you must, of course, first
-have given <strong>mom</strong> the appropriate
-<a href="docprocessing.html#REFERENCE_MACROS">reference macro</a>.
-A list of arguments with their equivalent reference macros follows.
-<br>
-
-<dl>
-<dt>TITLE
-<dd>-means the argument you gave to
-<a href="docprocessing.html#TITLE">TITLE</a>
-<dt>DOCTITLE
-<dd>-means the argument you gave to
-<a href="docprocessing.html#DOCTITLE">DOCTITLE</a>
-<dt>COVERTITLE
-<dd>-means the argument you gave to
-<a href="docprocessing.html#COVERTITLE">COVERTITLE</a>
-or
-<a href="docprocessing.html#DOC_COVERTITLE">DOC_COVERTITLE</a>
-<dt>CHAPTER, CHAPTER_TITLE, CHAPTER+TITLE
-<dd>-see below (How the CHAPTER argument and friends work)
-</dl>
-<br>
-
-<a name="CHAPTER"><h3><u>How the CHAPTER argument and friends work</u></h3></a>
-
-<kbd>CHAPTER</kbd>, by itself, will print the <a
-href="docprocessing.html#CHAPTER_STRING">CHAPTER_STRING</a> as well
-as the chapter number that you gave to
-<a href="docprocessing.html#CHAPTER">CHAPTER</a>.
-For example, assuming a vanilla setup for your chapter
-<p>
-<pre>
-	\# Reference macros
-	.CHAPTER 1
-	.CHAPTER_TITLE "The Bonny Blue Yonder"
-	&lt;other stuff&gt;
-	.COVER CHAPTER \" (or .DOC_COVER CHAPTER)
-	.START
-</pre>
-
-will simply print
-<p>
-<pre>
-	Chapter 1
-</pre>
-
-<kbd>CHAPTER_TITLE</kbd> will print the chapter title you
-gave to
-<a href="docprocessing.html#CHAPTER_TITLE">CHAPTER_TITLE</a>.
-For example, assuming a vanilla setup for your chapter
-<p>
-<pre>
-	\# Reference macros
-	.CHAPTER 1
-	.CHAPTER_TITLE "The Bonny Blue Yonder"
-	&lt;other stuff&gt;
-	.COVER CHAPTER_TITLE \" (or .DOC_COVER CHAPTER_TITLE)
-	.START
-</pre>
-
-will simply print
-<p>
-<pre>
-	The Bonny Blue Yonder
-</pre>
-
-<p>
-<kbd>CHAPTER+TITLE</kbd> will print <strong>both</strong> the
-chapter string + number AND the chapter title.  For example,
-assuming a vanilla setup for your chapter
-<p>
-<pre>
-	\# Reference macros
-	.CHAPTER 1
-	.CHAPTER_TITLE "The Bonny Blue Yonder"
-	&lt;other stuff&gt;
-	.COVER CHAPTER+TITLE \" (or .DOC_COVER CHAPTER+TITLE)
-	.START
-</pre>
-
-will print
-<p>
-<pre>
-	      Chapter 1
-	The Bonny Blue Yonder
-</pre>
-
-<a name="OPTIONAL"><h3><u>The optional arguments</u></h3></a>
-
-The remainder of the arguments to <strong>COVER</strong> and
-<strong>DOC_COVER</strong> are optional.  They refer specifically
-to the information you gave the
-<a href="docprocessing.html#REFERENCE_MACROS">reference macros</a>
-bearing the same name as the arguments.
-<p>
-You may enter as many or as few as you would like to see on your
-cover (or doc cover) page.  The only hitch is--PAY ATTENTION,
-CLASS!--they must be entered in the order given above.  For
-example, if you want <kbd>TITLE</kbd>, <kbd>AUTHOR</kbd>,
-<kbd>COPYRIGHT</kbd> and <kbd>MISC</kbd>
-<p>
-<pre>
-	.COVER TITLE AUTHOR COPYRIGHT MISC
-</pre>
-
-is correct, while
-<p>
-<pre>
-	.COVER TITLE AUTHOR MISC COPYRIGHT
-</pre>
-
-is not.
-<br>
-
-<a name="DOCTYPE"><h3><u>What the DOCTYPE argument means</u></h3></a>
-
-When you pass <strong>COVER</strong> or <strong>DOC_COVER</strong>
-the argument, <kbd>DOCTYPE</kbd>, it refers to the argument you
-gave to
-<a href="docprocessing.html#DOCTYPE">DOCTYPE</a>&nbsp;<kbd>NAMED</kbd>.
-For example, if, in your
-<a href="docprocessing.html#DOCSTYLE_MACROS">docstyle macros</a>
-you gave a
-<p>
-<pre>
-	.DOCTYPE NAMED "Abstract"
-</pre>
-
-the argument, <kbd>DOCTYPE</kbd>, in the <strong>COVER</strong> or
-<strong>DOC_COVER</strong> macros, would mean that you wanted the
-word, Abstract, to appear on the cover (or doc cover), just as it
-would in the 
-<a href="docprocessing.html#DOCHEADER">docheader</a>.
-<br>
-

-	<nobr>Macro: <strong>COVERS</strong> &lt;toggle&gt;</nobr>
-	<br>
-	<nobr>Macro: <strong>DOC_COVERS</strong> &lt;toggle&gt;</nobr>
-</a>
-<p>
-By default, if you give <strong>mom</strong> a
-<a href="#COVER">COVER</a>
-or
-<a href="#DOC_COVER">DOC_COVER</a>
-macro, she will print it.  In a document that contains sections,
-articles or chapters formerly treated as &quot;one-off's&quot; but
-now being
-<a href="rectoverso.html#COLLATE_INTRO">collated</a>,
-such behaviour may not be desirable.
-<p>
-<strong>Mom</strong> lets you selectively enable or disable the
-generation of covers and/or doc covers with the toggle macros
-<strong>COVERS</strong> and <strong>DOC_COVERS</strong>.  Because
-they're toggle macros, simply invoking them by themselves enables
-automatic cover (or doc cover) generation, while invoking them
-with any argument at all (<strong>OFF, QUIT, X</strong>, etc)
-disables cover (or doc cover) generation.
-<p>
-<strong>NOTE:</strong> You must place these macros prior to any
-instance of
-<a href="docprocessing.html#START">START</a>.  Since they're
-&quot;on&quot; by default, there's no need to use them if you want
-covers.  However, if you don't, especially in the kind of scenario
-described above, the best place to put them (most likely with an
-<strong>OFF, NO, X</strong>, etc. argument), is immediately after the
-first invocation of <strong>START</strong>.  By doing so, you ensure
-they precede all subsequent instances of <strong>START</strong>.

-<a name="COVER_CONTROL"><h3><u>Control macros--changing the defaults for covers and document covers</u></h3></a>
-The default typographic appearance of the items on a cover (or doc
-cover) page is identical to that of the items in a
-<a href="definitions.html#TERMS_DOCHEADER">docheader</a>.
-(See
-<a href="docprocessing.html#DOCHEADER_CONTROL">How to change the look of docheaders</a>
-for a description of the defaults.)
-<p>
-<a href="docprocessing.html#COPYRIGHT">COPYRIGHT</a>

-which do not appear in docheaders, have the following default
-characteristics:

-	<li>The copyright line is set in the bottom right hand corner
-		of the page, 2
-		<a href="definitions.html#TERMS_PS">point sizes</a>
-		smaller than the size of
-		<a href="definitions.html#TERMS_RUNNING">running text</a>
-	<li>The &quot;misc&quot; line is set in the bottom left hand
-		corner of the page, in the same family, font and point size
-		as the copyright line.
-</ol>
-<p>
-With the exception of the copyright and &quot;misc&quot; lines, the
-defaults for the entirety of cover (and doc cover) pages, and all
-the elements thereon, can be changed with control macros whose
-behaviour and arguments are identical to

-<dl>
-<dt><a name="TERMS_ASCENDER"><em>Ascender</em></a>
-<dd>The portion of a letter that extends above the bowl.  For example,
-the letters a, c, and e have no ascenders.  The letters b, d, and h
-do.
-
-<dt><a name="TERMS_BASELINE"><em>Baseline</em></a>
-<dd>The imaginary line on which the bottoms of capital letters and the
-bowls of lower case letters rest.
-
-<dt><a name="TERMS_BALLOTBOX"><em>Ballot box</em></a>
-<dd>An unfilled square, usually
-<a href="#TERMS_CAPHEIGHT">cap-height</a>
-in size, typically placed beside items in a checklist.
-
-<dt><a name="TERMS_BULLET"><em>Bullet</em></a>
-<dd>A small, filled circle typically found beside items or points in
-a list.
-
-<dt><a name="TERMS_CAPHEIGHT"><em>Cap-height</em></a>
-<dd>The height of the tallest capital letter in a given
-<a href="#TERMS_FONT">font</a>
-at the current
-<a href="#TERMS_PS">point size</a>.
-
-<dt><a name="TERMS_DESCENDER"><em>Descender</em></a>
-<dd>The portion of a letter that extends beneath the
-<a href="#TERMS_BASELINE">baseline</a>
-(j, q, y are letters with descenders).
-
-<dt><a name="TERMS_DISCRETIONARYHYPHEN"><em>Discretionary hyphen</em></a>
-<dd>A symbol inserted between two syllables of a word that indicates to a
-typesetting program the legal hyphenation points in the word.  Normally,
-if hyphenation is turned on, groff knows where to hyphenate words.
-However, hyphenation being what it is (in English, at any rate),
-groff doesn't always get it right.  Discretionary hyphens make sure
-it does.  In the event that the word doesn't need to be hyphenated
-at all, groff leaves them alone.  In groff, the discretionary hyphen is
-entered with
-<p>
-<pre>
-	\%
-</pre>
-
-(backslash followed by a percent).
-
-<dt><a name="TERMS_DROPCAP"><em>Drop cap</em></a>
-<dd>A large, usually upper-case letter that introduces the first
-paragraph of a document or section thereof.  The top of the drop
-cap usually lines up with the top of the first line of the
-paragraph, and typically &quot;drops&quot; several lines lower.
-Text adjacent to the drop cap is indented to the right of the
-letter until the bottom of the drop cap is reached, at which
-point text reverts to the left margin.
-
-<dt><a name="TERMS_EM"><em>Em/en</em></a>
-<dd>An em is a relative measurement equal to the width of the
-letter M at a given
-<a href="#TERMS_PS">point size</a>
-in a given
-<a href="#TERMS_FONT">font</a>.
-Since most Ms are designed square, an em is usually (but sometimes
-erroneously) considered to be the same size as the current point
-size (i.e. if the point size of the type is 12, one em equals 12
-points).  An en is equal to the width of a letter N (historically
-2/3 of an em, although groff treats an en as 1/2 of an em).
-Typically, ems and ens are used to measure indents, or to define the
-length of dashes (long hyphens).
-
-<dt><a name="TERMS_FAMILY"><em>Family</em></a>
-<dd>The collective name by which a collection of
-<a href="#TERMS_FONT">fonts</a>
-are known, e.g.  Helvetica, Times Roman, Garamond.
-
-<dt><a name="TERMS_FIGURESPACE"><em>Figure space/Digit space</em></a>
-<dd>A
-<a href="#TERMS_FIXEDWIDTHSPACE">fixed width space</a>
-that has the width of one digit.  Used for aligning numerals in,
-say, columns or numbered lists.  In groff, the figure space is
-entered with
-<p>
-<pre>
-	\0
-</pre>
-
-(backslash followed by a zero).
-
-<dt><a name="TERMS_FIXEDWIDTHSPACE"><em>Fixed width space</em></a>
-<dd>Equal to
-<a href="#TERMS_WORDSPACE">word space</a>,
-but does not expand or contract when text is
-<a href="#TERMS_JUST">justified</a>.
-In groff, fixed width space is entered with
-<p>
-<pre>
-	\&lt;space&gt;
-</pre>
-
-where &lt;space&gt; means "hit the spacebar on your keyboard."
-
-<dt><a name="TERMS_FONT"><em>Font</em></a>
-<dd>The specific
-<a href="#TERMS_WEIGHT">weight</a>
-and
-<a href="#TERMS_SHAPE">shape</a>
-of type within a
-<a href="#TERMS_FAMILY">family</a>,
-e.g. light, medium, bold (which are weights), and roman, italic,
-condensed (which are shapes).  By default, groff knows of four fonts
-within its default set of families: R (medium roman), I (medium
-italic), B (bold roman) and BI (bold italic).
-
-<dt><a name="TERMS_FORCE"><em>Force justify
-</em></a>
-<dd>Sometimes, in
-<a href="#TERMS_JUST">justified</a>
-text, a line needs to be broken short of the right margin.  Force
-justifying means telling a typesetting program (like groff) that you
-want the line broken early AND that you want the line's word spacing
-stretched to force the line flush with the right margin.
-
-<dt><a name="TERMS_GUTTER"><em>Gutter</em></a>
-<dd>The vertical whitespace separating columns of type.
-
-<dt><a name="TERMS_JUST"><em>Justify/justification</em></a>
-<dd>Lines of type are justified when they're flush at both the left and
-right margins.  Justification is the act of making both margins flush.
-Some people use the terms "left justified" and "right justified"
-to mean type where only the left (or right) margins align.  I don't.
-See
-<a href="#TERMS_QUAD">quad</a>.
-
-<dt><a name="TERMS_KERN"><em>Kerning</em></a>
-<dd>Moving pairs of letters closer together to remove excess
-whitespace between them.  In the days before phototypesetting,
-type was set from small, rectangular blocks of wood or metal, each
-block having exactly one letter.  Because the edge of each block
-determined the edge of each letter, certain letter combinations (TA,
-for example) didn't fit together well and had to be mortised by hand
-to bring them visually closer.  Modern typesetting systems usually
-take care of kerning automatically, but they're far from perfect.
-Professional typesetters still devote a lot of time to fitting letters
-and punctuation together properly.
-
-<dt><a name="TERMS_KERNUNIT"><em>Kern Units</em></a>
-<dd>A relative distance equal to 1/36 of the current
-<a href="#TERMS_PS">point size</a>.
-Used between individual letters
-for
-<a href="#TERMS_KERN">kerning</a>.
-Different typesetting systems use different values (1/54 is
-popular), and sometimes call kern units by a different name.
-<p>
-<strong>Experts:
-<br></strong>A kern unit has nothing to do with groff
-machine units.
-
-<dt><a name="TERMS_LEADING"><em>Lead/leading</em></a>
-<dd>The distance from the
-<a href="#TERMS_BASELINE">baseline</a>
-of one line of type to the line of type immediately beneath it.
-Pronounced "ledding."  Also called line spacing.  Usually measured
-in
-<a href="#TERMS_PICASPOINTS">points</a>.
-<p>
-<em>In case you're interested...</em> In previous centuries,
-lines of type were separated by thin strips of--you guessed
-it--lead.  Lines of type that had no lead between them were said to
-be &quot;set solid.&quot; Once you began separating them with strips
-of lead, they were said to be &quot;leaded&quot;, and the spacing was
-expressed in terms of the number of
-<a href="#TERMS_PICASPOINTS">points</a>
-of lead.  For this reason, &quot;leading&quot; and &quot;line
-spacing&quot; aren't, historically speaking, synonymous.  If type
-was set 10 on 12, for example, the leading was 2 points, not 12.
-Nowadays, however, the two terms are used interchangeably to mean
-the distance from baseline to baseline.
-
-<dt><a name="TERMS_LEADER"><em>Leaders</em></a>
-<dd>Single characters used to fill lines, usually to their end.
-So called because they &quot;lead&quot; the eye from one element
-of the page to another.  For example, in the following (brief)
-Table of Contents, the periods (dots) are leaders.
-<p>
-<pre>
-	Foreword............... 2
-	Chapter 1.............. 5
-	Chapter 2.............. 38
-	Chapter 3.............. 60
-</pre>
-
-<dt><a name="TERMS_LIGATURES"><em>Ligature</em></a>
-<dd>Ligatures are letters joined together to form a single character.
-The commonest are fi, fl, ff, ffi and ffl.  Others are ae and oe.
-Occasionally, one sees an st ligature, but this is archaic and
-quite rare.
-
-<dt><a name="TERMS_PICASPOINTS"><em>Picas/Points</em></a>
-<dd>There are twelve points in a pica, and six picas in an inch
-(hence 72 points to the inch).  In the same way that gem-dealers
-have always used their own system of measurement for weight (carats),
-typographers have always used their own system of measurement for type.
-
-<dt><a name="TERMS_PS"><em>Point Size</em></a>
-<dd>The nominal size of type, measured in
-<a href="#TERMS_PICASPOINTS">points</a>
-from the bottom of the longest
-<a href="#TERMS_DESCENDER">descender</a>
-to the top of the highest
-<a href="#TERMS_ASCENDER">ascender</a>.
-In reality, type is always fractionally smaller than its point size.
-
-<dt><a name="TERMS_QUAD"><em>Quad</em></a>
-<dd>When only one margin of type is flush, lines of type are quadded in
-the direction of the flush margin.  Therefore, quad left means the
-left margin is flush, the right isn't.  Quad right means the right
-margin is flush, the left isn't.  Quad centre means neither the left
-nor the right margin is flush; rather, lines of type are quadded on
-both sides so that type appears centred on the page.
-
-<dt><a name="TERMS_RAG"><em>Rag</em></a>
-<dd>Describes a margin that isn't flush.  Rag right means the right
-margin isn't flush.  Rag left means the left margin isn't flush.
-The expression "flush left/rag right" is sometimes used to describe
-type that is
-<a href="#TERMS_QUAD">quadded</a>
-left.
-
-<dt><a name="TERMS_SHAPE"><em>Shape</em></a>
-<dd>The degree of slant and/or the width of characters.
-(Technically speaking, this is not a proper typesetting term;
-however, it may help clarify some concepts presented in these
-documents.)
-<p>
-Some typical shapes are:
-<ul>
-	<li>&quot;Roman&quot;, which has no slant, and has letterforms of
-		average width
-	<li>&quot;Italic&quot;, which is slanted, and has letterforms
-		of average width
-	<li>&quot;Condensed&quot;, which has no slant, but has
-		letterforms narrower than the average represented by Roman
-	<li>&quot;Condensed Italic&quot;, which is slanted, with letterforms narrower
-		than average
-</ul>
-The term
-<a href="#TERMS_FONT">font</a>,
-as it is used in these documents, refers to a combination of
-<a href="#TERMS_WEIGHT">weight</a>
-and shape.
-
-<dt><a name="TERMS_SOLID"><em>Solid/set solid</em></a>
-<dd>When no
-<a href="#TERMS_LEADING">lead</a>
-is added between lines of type (i.e. the
-<a href="#TERMS_PS">point size</a>
-and linespacing are the same), the lines are said to be &quot;set
-solid.&quot;
-
-<dt><a name="TERMS_TRACKKERNING"><em>Track kerning/Line kerning</em></a>
-<dd>Sometimes, it's advantageous to increase or decrease the amount of
-space between every letter in a line by an equal (usually small)
-amount, in order to fit more (or fewer) characters on the line.
-The correct term is letter spacing, but track kerning and line kerning
-(and sometimes, just "kerning") have come to mean the same thing.
-
-<dt><a name="TERMS_UNBREAKABLESPACE"><em>Unbreakable space</em></a>
-<dd>Equal to
-<a href="#TERMS_WORDSPACE">word space</a>,
-however words separated by an unbreakable space will always be kept
-together on the same line.  Expands and contracts like word space.
-Useful for proper names, which one should, whenever possible, avoid
-splitting onto two lines.  In groff, unbreakable space is entered
-with
-<p>
-<pre>
-	\~
-</pre>
-
-(backslash followed by a tilde).
-
-<dt><a name="TERMS_WEIGHT"><em>Weight</em></a>
-<dd>The thickness of the strokes of letterforms.  Medium and Book
-have average thicknesses and are the weights used for most of the
-text in books, magazines, newspapers, etc.  Light has strokes
-slightly thinner than Medium or Book, but is still acceptable for
-most text.  Semibold, Bold, Heavy and Black all have strokes of
-increasing thickness, making them suitable for heads, subheads,
-headlines and the like.
-
-<dt><a name="TERMS_WORDSPACE"><em>Word space</em></a>
-<dd>The amount of whitespace between words.  When text is
-<a href="#TERMS_JUST">justified</a>,
-word space expands or contracts to make the margins flush.
-
-<dt><a name="TERMS_XHEIGHT"><em>x-height</em></a>
-<dd>The height of a lower case letter x in a given font at a given
-point size.  Generally used to mean the average height of the bowl
-of lower case letters.

-to do its job.  For example, in the macro
-<p>
-<pre>
-	.PT_SIZE 12
-</pre>

-<dd>Instructions to groff that appear on a line by themselves,
-which means that &quot;control lines&quot; are either
-<a href="#TERMS_MACROS">macros</a>
-or groff
-<a href="#TERMS_PRIMITIVES">primitives</a>.

-<dd>Automatic
-<a href="#TERMS_JUST">justification</a>
-or
-<a href="#TERMS_QUAD">quadding</a>.
-In fill mode, the ends of lines as they appear in your text editor
-are ignored.  Instead, words from adjoining
-<a href="#TERMS_INPUTLINE">input lines</a>
-are added one at a time to the output line until no more words fit.
-Then, depending whether text is to be
-<a href="#TERMS_JUST">justified</a>
-or
-<a href="#TERMS_QUAD">quadded</a>
-(left, right, or centre), and depending on whether automatic
-hyphenation is turned on, groff attempts to hyphenate the last word,
-or, barring that, spreads and breaks the line (when justification
-is turned on) or breaks and quads the line (when quadding is turned
-on).
-<p>
-<a name="TERMS_NOFILL"></a>
-Nofill mode (non-filled text) means that groff respects the ends

-
-<dt><a name="TERMS_INLINES"><em>Inline escapes</em></a>
-<dd>Instructions issued to groff that appear as part of an
-<a href="#TERMS_INPUTLINE">input line</a>
-(as opposed to
-<a href="#TERMS_MACROS">macros</a>,
-which must appear on a line by themselves).  Inline escapes are
-always introduced by the backslash character.  For example,
-<p>
-<pre>
-	A line of text with the word T\*[BU 2]oronto in it
-</pre>
-
-contains the inline escape \*[BU 2] (which means &quot;move the letter
-'o' 2
-<a href="#TERMS_KERNUNIT">kern units</a>
-closer to the letter 'T'&quot;).
-<p>
-<strong>Mom</strong>'s inline escapes always take the form
-<strong>\*[</strong><i>ESCAPE</i><strong>]</strong>, where <i>ESCAPE</i>
-is composed of capital letters, sometimes followed immediately
-by a digit, sometimes followed by a space and a
-<a href="#TERMS_NUMERICARGUMENT">numeric argument</a>.
-<strong>Groff</strong>'s escapes begin with the backslash character
-but typically have no star and are in lower case.  For example, the
-<strong>mom</strong> escapes to move forward 6 points on a line are
-either
-<p>
-<pre>
-	\*[FP6]&nbsp;&nbsp;or&nbsp;&nbsp;\*[FWD 6p]
-</pre>
-
-while the <strong>groff</strong> escape for the same thing is
-<p>
-<pre>
-	\h'6p'
-</pre>
-
-<dt><a name="TERMS_INPUTLINE"><em>Input line</em></a>
-<dd>A line of text as it appears in your text editor.
-
-<dt><a name="TERMS_MACROS"><em>Macros</em></a>
-<dd>Instructions embedded in a document that determine how groff processes
-the text for output.  <strong>mom</strong>'s macros always begin with a
-period, on a line by themselves, and must be typed in capital letters.
-Typically, macros contain complex commands issued to groff--behind
-the scenes--via groff
-<a href="#TERMS_PRIMITIVES">primitives</a>.
-
-<dt><a name="TERMS_UNITS"><em>Machine units</em></a>
-<dd>A machine unit is 1/1000 of a
-<a href="#TERMS_PICASPOINTS">point</a>
-when the groff device is ps. (&quot;ps&quot; means
-&quot;PostScript&quot;--the default device for which groff
-prepares output, and the device for which <strong>mom</strong> was
-specifically designed.)
-
-<dt><a name="TERMS_NUMERICARGUMENT"><em>Numeric argument</em></a>
-<dd>An
-<a href="#TERMS_ARGUMENT">argument</a>
-that has the form of a digit.  Numeric arguments can be built out
-of arithmetic expressions using +, -, *, and / for plus, minus,
-times, and divided-by respectively.  If a numeric argument requires
-a
-<a href="#TERMS_UNITOFMEASURE">unit of measure</a>,
-a unit of measure must be appended to <em>every</em> digit in the
-argument.  For example:
-<p>
-<pre>
-	.ALD 1i-1v
-</pre>
-
-<strong>NOTE:</strong> groff does not respect the order of operations,
-but rather evaluates arithmetic expressions from left to right.
-Parentheses must be used to circumvent this peculiarity.  Not to
-worry, though.  The likelihood of more than just the occasional plus
-or minus sign when using <strong>mom</strong>'s macros is slim.
-
-<dt><a name="TERMS_OUTPUTLINE"><em>Output line</em></a>
-<dd>A line of text as it appears in output copy.
-
-<dt><a name="TERMS_PRIMITIVES"><em>Primitives</em></a>
-<dd>The two-letter, lower case instructions groff uses as its
-native command language, and out of which macros are built.
-
-<dt><a name="TERMS_STRINGARGUMENT"><em>String Argument</em></a>
-<dd>Technically, any
-<a href="#TERMS_ARGUMENTS">argument</a>
-that is not numeric.  In this documentation, string argument means
-an argument that requires the user to input text.  For example, in
-the
-<a href="#TERMS_MACROS">macro</a>
-<p>
-<pre>
-	.TITLE "My Pulitzer Novel"
-</pre>
-
-&quot;My Pulitzer Novel&quot; is a string argument.
-<p>
-Because string arguments must be enclosed by double-quotes, you can't
-use double-quotes as part of the string argument.  If you need
-double-quotes to be part of a string argument, use the
-<a href="#TERMS_INLINES">inline escapes</a>
-<strong>\(lq</strong> and <strong>\(rq</strong> (leftquote and rightquote
-respectively) in place of the double-quote character (").
-
-<dt><a name="TERMS_UNITOFMEASURE"><em>Unit of measure</em></a>
-<dd>The single letter after a
-<a href="#TERMS_NUMERICARGUMENT">numeric argument</a>
-that tells <strong>mom</strong> what measurement scale the argument
-should use.  Common valid units are:
-<p>
-<table valign="baseline" summary="unitsofmeasure">
-<tr><td><strong>i</strong><td> = <td>inches
-<tr><td><strong>p</strong><td> = <td>points
-<tr><td><strong>P</strong><td> = <td>picas
-<tr><td><strong>c</strong><td> = <td>centimetres
-<tr><td><strong>m</strong><td> = <td>ems
-<tr><td><strong>n</strong><td> = <td>ens
-<tr><td><strong>v</strong><td> = <td>the current leading (line space)</td></tr>
-</table>
-<br>
-<dd>Units of measure must come immediately after the numeric argument (i.e.
-with no space between the argument and the unit of measure), like this:
-<p>
-<pre>
-	.ALD 2v
-	.LL  39P
-	.IL  1i
-</pre>
-
-The above example advances 2 line spaces and sets the line length to
-39 picas with a left indent of 1 inch.
-<p>
-<strong>IMPORTANT:</strong> Most <strong>mom</strong> macros
-that set the size or measure of something MUST be given a unit of
-measure.  <strong>mom</strong>'s macros do not have default units
-of measure.  There are a couple of exceptions, the most notable of
-which are <strong>PT_SIZE</strong> and <strong>LS</strong>.  Both use
-<a href="#TERMS_PICASPOINTS">points</a>
-as the default unit of measure, which means
-you don't have to append &quot;p&quot; to their argument.
-<p>
-You can enter decimal values for any unit of measure.  Different units
-may be combined by adding them together (e.g. 1.5i+2m, which gives a
-measure of 1-1/2 inches plus 2 ems).
-<p>
-<strong>NOTE:</strong> a pica is composed of 12 points,
-therefore 12.5 picas is 12 picas and 6 points, not 12 picas
-and 5 points.  If you want 12 picas and 5 points, you have to
-enter the measure as 12P+5p.
-
-<dt><a name="TERMS_ZEROWIDTHCHARACTER"><em>Zero-width character</em></a>
-<dd>The
-<a href="#TERMS_INLINES">inline escape</a>
-that allows you to print a literal period, apostrophe and, if
-<a href="#TERMS_OUTPUTLINE">output lines</a>
-are
-<a href="#TERMS_FILLED">filled</a>,
-a space that falls at the beginning of an
-<a href="#TERMS_INPUTLINE">input line</a>.
-It looks like this:
-<p>
-<pre>
-	\&amp;
-</pre>
-
-(backslash followed by an ampersand).
-<p>
-Normally, groff interprets a period (or an apostrophe) at the beginning
-of an input line as meaning that what follows is a
-<a href="#TERMS_CONTROLLINES">control line</a>.
-In fill modes, groff treats a space at the beginning of an input
-line as meaning &quot;start a new line and put a space at the
-beginning of it.&quot; If you want groff to interpret periods and
-apostrophes at the beginning of input lines literally (i.e. print
-them), or spaces at the beginning of input lines as just garden
-variety word spaces, you must start the line with the zero-width
-character.

-	<h2><u>Introduction to the document element tags</u></h2>
-</a>
-
-Once you've completed the setup for a document (see
-<a href="docprocessing.html#DOCPROCESSING_TUT">Setting up a mom document</a>),
-formatting it is a snap.  Simply invoke the appropriate tag for
-each document element as you need it.  The tags are macros that
-tell <strong>mom</strong>, &quot;This is a paragraph, this
-is a subhead, this is a footnote,&quot; and so on.
-<p>
-The list of tags is actually quite small -- ideal for the users
-<strong>mom</strong> brought herself into being for (see
-<a href="intro.html#INTRO_INTRO">Who mom is meant for</a>).
-However, the list of macros that control the appearance of the
-tags upon output is extensive.  Generally, for each tag,
-there are
-<a href="definitions.html#TERMS_CONTROLMACRO">control macros</a>
-for the tag's family, font and point size.  Where appropriate, there
-are macros to control leading, indents, quad and special features
-as well.
-<p>
-<strong>Mom</strong> has tasteful defaults for all the tags, hence you
-only use the control macros when you want to change the way
-she does things.  This is usually done prior to
-<a href="docprocessing.html#START">START</a>,
-but can, in fact, be done at any time in the course of a document.
-Any change to a tag's style affects all subsequent invocations of
-the tag.
-<p>
-
-<a name="DOCELEMENT_CONTROL"><h3><u>Control macros -- changing defaults</u></h3></a>
-
-<p>
-The control macros for document processing tags let you
-&quot;design&quot; the look of all the parts of your documents --
-should you wish.  At a bare minimum, all tags have macros to change
-<strong>mom</strong>'s defaults for family, font, point size and
-colour.  Where appropriate, there are macros to control leading,
-indents and quad as well.
-<p>
-In addition, many tags have special macros to control features that
-are pertinent to those tags alone.  Have a look at the section dealing
-with any particular tag to find out what macros control the tag,
-and what <strong>mom</strong>'s defaults for the tag are.
-<p>
-The control macros may be used at any time during the course of
-a document (i.e. before or after
-<a href="docprocessing.html#START">START</a>).  The changes you
-make alter all subsequent invocations of the affected tag until
-you make another change, either by passing new arguments to the
-tag's control macro, or toggling a particular feature of the tag on
-or off.
-<p>
-And don't forget: the
-<a href="typesetting.html#MACROS_TYPESETTING">typesetting macros</a>
-can be used at any time, including inside
-<a href="definitions.html#TERMS_TOGGLE">toggle</a>
-tags (affecting only that particular invocation of the tag).
-Equally,
-<a href="definitions.html#TERMS_INLINES">inline escapes</a>
-can be used in tags that take
-<a href="definitions.html#TERMS_STRINGARGUMENT">string arguments.</a>
-<p>
-<strong>IMPORTANT NOTE:</strong> The family, font, point size,
-colour and leading control macros have no effect in
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE TYPEWRITE</a>,
-which sets EVERYTHING in Courier roman, 12/24 (i.e. 12-point type on
-a linespace of 24 points).
-<p>
-Please also note that the defaults listed
-with the control macros apply only to
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE TYPESET</a>
-unless a default for <strong>TYPEWRITE</strong> is also given.
-<p>
-<strong>A WORD OF ADVICE:</strong> Get familiar with
-<strong>mom</strong> at her default settings before exploring the
-control macros.  Put her through her paces.  See how she behaves.
-Get to know what she feels like and how she looks, both in your text
-editor and on the printed page.  Then, if you don't like something,
-use this documentation to find the precise macro you need to change it.
-There are tons of control macros.  Reading up on them and trying to
-remember them all might lead you to think that <strong>mom</strong>
-is complex and unwieldy, which is not only untrue, but would offend
-her mightily.
-<p>
-
-<a name="CONTROL_MACRO_ARGS"><h3><u>Arguments to the control macros</u></h3></a>
-
-<h3>Family and font</h3>
-The arguments to the control macros that end in
-<strong>_FAMILY</strong> or <strong>_FONT</strong> are the same
-as for
-<a href="typesetting.html#FAMILY">FAMILY</a>
-and
-<a href="typesetting.html#FONT">FT</a>.
-
-<h3>Point size</h3>
-Control macros that end in <strong>_SIZE</strong> always take
-the form <kbd>+digit</kbd> or <kbd>-digit</kbd> where digit is
-the number of
-<a href="definitions.html#TERMS_PICASPOINTS">points</a>
-larger (+) or smaller (-) than the point size of paragraphs
-you want the document element to be.  For example, to change
-subheads to 1-1/2 points larger than the type in paragraphs, do
-<p>
-<pre>
-	.SUBHEAD_SIZE +1.5
-</pre>
-
-There's no need for a
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-with the <strong>_SIZE</strong> control macros; points is assumed.
-
-<h3>Colour</h3>
-Control macros that end in <strong>_COLOR</strong> take as their
-argument a colour name pre-defined (or &quot;initialized&quot;)
-with
-<a href="color.html#NEWCOLOR">NEWCOLOR</a>
-or
-<a href="color.html#XCOLOR">XCOLOR</a>.
-For example, if you want your heads to be red, once you've defined
-or initialized the color, red,
-<p>
-<pre>
-	.HEAD_COLOR red
-</pre>
-
-will turn your heads red.
-
-<h3>Lead/linespacing</h3>
-Control macros that end in <strong>_AUTOLEAD</strong> take the
-same argument as
-<a href="typesetting.html#AUTOLEAD">AUTOLEAD</a>,
-viz. a digit that represents the number of points to add to the
-tag's point size to arrive at its
-<a href="definitions.html#TERMS_LEADING">lead</a>.
-For example, to set footnotes
-<a href="definitions.html#TERMS_SOLID">solid</a>, do
-<p>
-<pre>
-	.FOOTNOTE_AUTOLEAD 0
-</pre>
-
-To set footnotes with a 1-point lead (i.e. with the line spacing
-one point greater than the footnote's point size), do
-<p>
-<pre>
-	.FOOTNOTE_AUTOLEAD 1
-</pre>
-
-<h3><a name="CONTROL_INDENTS">Indents</a></h3>
-Except for <strong>PARA_INDENT</strong>, the argument to the control
-macros that end
-in <strong>_INDENT</strong> is always a single digit (whole numbers
-only; no decimal fractions) with no
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-appended to it.  The digit represents by how much you want the
-size of the paragraph first-line indent multiplied to achieve the
-correct indent for a particular tag.
-
-<h3>Quad/justification style</h3>
-Control macros that end in <strong>_QUAD</strong> take the same
-arguments as
-<a href="typesetting.html#QUAD">QUAD</a>.

-If a block-style epigraph runs to more than one paragraph (unlikely,

-<ul>
-	<li><a href="#PP">Tag: PP</a>
-	<li><a href="#PP_CONTROL">Paragraph control macros</a>
-</ul>
-<p>
-The paragraph macro is the one you use most often.  Consequently,
-it's one of most powerful, yet simplest to use -- just the letters
-<strong>PP</strong>.  No arguments, nothing.  Just <kbd>.PP</kbd>
-on a line by itself any time, in any document element, tells
-<strong>mom</strong> you want to start a new paragraph.  The spacing
-and indent appropriate to where you are in your document are taken
-care of automatically.
-<p>
-By default, <strong>mom</strong> does not indent the first paragraph
-of a document, nor paragraphs that fall immediately after
-<a href="#HEAD_INTRO">heads</a>
-or
-<a href="#SUBHEAD_INTRO">subheads</a>.
-The first paragraphs of blockquotes and block-style epigraphs are
-also not indented.  This behaviour can be changed with the control
-macro
-<a href="#PARA_INDENT_FIRST">INDENT_FIRST_PARAS</a>.
-<p>
-In contrast to some other macro packages, <strong>mom</strong> does not
-deposit a blank line between paragraphs.  If you want her to do so, use
-the control macro <strong>PARA_SPACE</strong>.  (I don't recommend
-using this macro with
-<a href="typesetting.html#PRINTSTYLE">PRINTSTYLE TYPEWRITE</a>.)
-<p>
-Note that <strong>mom</strong> does not provide &quot;orphan
-control&quot; for paragraphs (i.e. even if only one line of a paragraph
-fits at the bottom of a page, she will set it on that page).  The
-reason for this is that writers of fiction often have single-line
-paragraphs (e.g. in dialogue).  Groff's simplistic orphan control
-will break these one-liners -- if they fall at the bottom of the page
--- to a new page, which is not what you want.
-<p>
-<strong>TIP:</strong> The last thing you want while you're writing
-and editing drafts of a document (particularly stories and chapters)
-is a text file cluttered up with <strong>PP</strong>'s.  The visual
-interruption in the flow of text is a serious obstacle to creativity
-and critiquing.
-<p>
-I use the tab key on my keyboard to indent paragraphs when I'm writing,
-producing a text file that looks pretty much like what you see on
-a printed page.  When it comes time to format and print the file,
-I run it through a sed script that (amongst other things) converts
-the character generated by the tab key (<kbd>^I</kbd>) into <code>.PP</code>
-(plus a new line), and pipe the output to groff for processing and
-printing.
-<p>
-Another solution is to insert a blank line between paragraphs.
-The blank lines can then be sedded out at print time as above, or,
-more conveniently, you can use the <code>.blm</code>
-<a href="definitions.html#TERMS_PRIMITIVES">primitive</a>
-(blank line macro) to instruct groff (and <strong>mom</strong>)
-that blank lines should be interpreted as <strong>PP</strong>'s.
-<p>
-<pre>
-	.blm PP
-</pre>
-tells groff that all blank lines are really the macro <strong>PP</strong>.

-prior to

-<a href="docprocessing.html#DOC_FAMILY">DOC_FAMILY</a>
-afterwards.  Please note that both globally affect the family of
-every element in the document.
-<p>
-If you wish to change the family for regular
-text paragraphs only, invoke <strong>FAMILY</strong> immediately

-which takes the same argument as
-<a href="typesetting.html#FONT">FT</a>.
-<strong>PP_FONT</strong> may be used before or after

-<a href="#FOOTNOTE_INTRO">footnotes</a>

-
-<a name="PP_COLOR"><h3><u>3. Paragraph colour</u></h3></a>
-<p>
-<strong>Mom</strong> has no special control macro for colourizing
-paragraphs.  If you wish a colourized paragraph, you must use the
-macro,
-<a href="color.html#COLOR">COLOR</a>,
-or the
-<a href="definitions.html#TERMS_INLINE">inline escape</a>,
-<a href="color.html#COLOR_INLINE">\*[&lt;colorname&gt;]</a>,
-<em>after</em> <strong>.PP</strong>.  The colour must be one
-pre-defined (or &quot;initialized&quot;) with
-<a href="color.html#NEWCOLOR">NEWCOLOR</a>
-or
-<a href="color.html#XCOLOR">XCOLOR</a>.
-<p>
-Please note that unless you change the colour back to it's default
-(usually black) at the end of the paragraph, all subsequent
-paragraphs will be set in the new colour, although most other
-elements of your document will continue to be set in the default
-colour (usually black).
-<p>
-For example, assuming you have defined the colour, blue,
-<p>
-<pre>
-	.PP
-	.COLOR blue
-	&lt;first paragraph&gt;
-	.HEAD "Monty Python"
-	.SUBHEAD "The Origins of Spam"
-	.PP
-	&lt;second paragraph&gt;
-</pre>
-
-the first paragraph will be blue, the head and subhead will be in
-the document's default colour (usually black), and the second
-paragraph will be in blue.
-<p>
-The one document element that is affected by changing the colour
-of paragraphs are
-<a href="#PARAHEAD">paraheads</a>,
-since they are attached directly to the body of paragraphs.  In
-other words, if you change the colour of a paragraph and do not
-reset the paragraph colour back to its default, subsequent paraheads
-will appear in the same colour as your paragraphs unless you have
-explicitly told <strong>mom</strong> you want a pre-defined (or
-&quot;initialized&quot;) color (usually black) for your paraheads.
-<p>
-See the footnote to
-<a href="#PARAHEAD_COLOR">.PARAHEAD_COLOR</a>.
-
-<a name="PP_LEADING"><h3><u>4. Leading</u></h3></a>
-<p>
-The paragraph

-prior to

-afterwards.  Please note that either method globally affects the
-leading and spacing of every document element (except
-<a href="definitions.html#TERMS_HEADER">headers</a>
-and
-<a href="definitions.html#TERMS_FOOTER">footers</a>).
-<p>
-If you wish to change the leading of regular text paragraphs only,
-invoke <strong>LS</strong> immediately after <strong>PP</strong> in
-EVERY paragraph whose leading you wish to change.
-<p>
-<strong>HYPER-IMPORTANT NOTE:</strong> It is extremely unwise to change
-paragraph leading with <strong>LS</strong>, as it will, in all cases,
-screw up <strong>mom</strong>'s ability to balance the bottom margin
-of pages.  Should you absolutely need to change paragraph leading
-with <strong>LS</strong>, and subsequently want <strong>mom</strong>
-to get back on the right leading track, use the
-<a href="docprocessing.html#SHIM">SHIM</a>
-macro.

-<p>
-The first-line indent of paragraphs is controlled by
-<strong>PARA_INDENT</strong>, which takes one argument: the size
-of the indent.  <strong>PARA_INDENT</strong> may be used before
-or after
-<a href="docprocessing.html#START">START</a>.
-A
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-is required; fractional sizes are allowed.  Thus, to set the paragraph
-indent to 4-1/2
-<a href="definitions.html#TERMS_EM">ems</a>, do
-<p>
-<pre>
-	.PARA_INDENT 4.5m
-</pre>
-
-In addition to establishing the basic first line-indent of
-paragraphs, <strong>PARA_INDENT</strong> also affects
-<a href="#EPIGRAPH_INTRO">epigraphs</a>,
-<a href="#QUOTE_INTRO">quotes</a>
-and
-<a href="#BLOCKQUOTE_INTRO">blockquotes</a>,
-whose overall indenting from the left and (where applicable) right
-margins is relative to <strong>PARA_INDENT</strong>.  Furthermore, the
-first-line indent of paragraphs within these document elements (as well
-as footnotes) is also relative to <strong>PARA_INDENT</strong> (always
-1/2 of <strong>PARA_INDENT)</strong>), hence they are also affected.
-<p>
-<strong>Mom</strong>'s default <strong>PARA_INDENT</strong> is 2
-ems for
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE_TYPESET</a>

-<a name="PARA_INDENT_FIRST"><h3><u>7. Indenting initial paragraphs -- INDENT_FIRST_PARAS</u></h3></a>
-<p>
-By default, <strong>mom</strong> does not indent the first paragraph

-<a href="#EPIGRAPH_INTRO">epigraphs</a>,
-<a href="#BLOCKQUOTE_INTRO">blockquotes</a>
-or
-<a href="#FOOTNOTE_INTRO">footnotes</a>
-that run to more than one paragraph.
-<a name="INDENT_FIRST_PARAS"></a>
-<p>
-If you wish to have first paragraphs indented, invoke the macro
-<strong>.INDENT_FIRST_PARAS</strong> with no argument, either
-before or after
-<a href="docprocessing.html#START">START</a>.
-<strong>INDENT_FIRST_PARAS</strong> is a toggle macro, therefore

-<p>
-
-<a name="PP_SPACE"><h3><u>8. Spacing paragraphs -- PARA_SPACE</u></h3></a>
-<p>
-By default, <strong>mom</strong> does not insert a blank line

-before or after
-<a href="docprocessing.html#START">START</a>.
-<strong>PARA_SPACE</strong> is a toggle macro, therefore passing
-it any argument (<strong>OFF, QUIT, Q, X</strong>...) cancels its
-effect, meaning that paragraphs will once again NOT be separated by
-a blank line.
-<p>
-<strong>NOTE:</strong> If <strong>PARA_SPACE</strong> is on,
-<strong>mom</strong> spaces only those paragraphs that come after
-an &quot;initial&quot; paragraph.  Initial paragraphs are those
-that come immediately after the

-(The first paragraph after these document elements requires no
-blank line to separate it from other paragraphs.)
-<p>
-Sometimes, you can be fairly deep into a document before using
-<strong>.PP</strong> for the first time, and when you do, because
-<strong>mom</strong> is still waiting for that &quot;initial&quot;
-paragraph, she doesn't space it with a blank line, even though
-you expect her to.  The simple workaround for this is to invoke

-The argument to <strong>HEAD</strong> is the text of the head,

-<strong>NOTE:</strong> If a head falls near the bottom of an output page

-<strong>LINEBREAK_CHAR</strong> determines what <strong>mom</strong>
-prints when <strong>LINEBREAK</strong> is invoked.  It takes 3
-optional arguments: the character you want deposited at the line
-break, the number of times you want the character repeated, and a
-vertical adjustment factor.
-<p>
-The first argument is any legal groff character (e.g. <kbd>*</kbd>
-[an asterisk], <kbd>\(dg</kbd> [a dagger], <kbd>\f(ZD\N'141\fP</kbd>
-[an arbitrary character from Zapf Dingbats], <kbd>\l'4P'</kbd>
-[a 4-pica long rule]).  <strong>Mom</strong> sets the character
-centred on the current line length.  (See &quot;man groff_char&quot;
-for a list of all legal groff characters.)
-<p>
-The second argument is the number of times to repeat the character.
-<p>
-The third argument is a +|- value by which to raise (+) or lower (-)
-the character in order to make it appear visually centred between
-sections of text.  This lets you make vertical adjustments
-to characters that don't sit on the
-<a href="definitions.html#TERMS_BASELINE">baseline</a>
-(such as asterisks).  The argument must be preceded by a plus or
-minus sign, and must include a unit of measure.
-<p>
-If you enter <strong>LINEBREAK_CHAR</strong> with no arguments,
-sections of text will be separated by two blank lines when you invoke
-<strong>LINEBREAK</strong>.
-<p>
-<strong>Mom</strong>'s default for <strong>LINEBREAK_CHAR</strong> is
-<p>
-<pre>
-	.LINEBREAK_CHAR * 3 -3p
-</pre>
-
-i.e. three asterisks, lowered 3 points from their normal vertical
-position (for
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE TYPESET</a>;
-the vertical adjustment is -2 points for

-(See

-<p>
-Since <strong>mom</strong> originally came into being to serve
-the needs of creative writers (i.e. novelists, short story
-writers, etc. -- not to cast aspersions on the creativity of
-mathematicians and programmers), she sets quotes in italics
-<a href="docprocessing.html#PRINTSTYLE">(PRINTSTYLE TYPESET)</a>
-or underlined
-<a href="docprocessing.html#PRINTSTYLE">(PRINTSTYLE TYPEWRITE)</a>,
-indented from the left margin.  Obviously, she's thinking
-&quot;quotes from poetry or song lyrics&quot;, but with the
-<a href="#QUOTE_CONTROL">quote control macros</a>
-you can change her defaults so <strong>QUOTE</strong> serves other
-needs, e.g. entering verbatim snippets of programming code, command
-line instructions, and so on.  (See the
-<a href="#QUOTE_TIP">tip</a>
-below for suggestions about including programming code snippets in
-documents.)
-<p>
-<a name="QUOTE_SPACING"></a>
-Besides indenting quotes, <strong>mom</strong> further sets them
-off from
-<a href="definitions.html#TERMS_RUNNING">running text</a>
-with a small amount of vertical whitespace top and bottom.  In
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE TYPEWRITE</a>,
-this is always one full linespace.  In
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE TYPESET</a>,
-it's 1/2 of the prevailing
-<a href="definitions.html#TERMS_LEADING">leading</a>
-if the quote fits fully on the page (i.e. with running text above
-and below it), otherwise it's a full linespace either above or below
-as is necessary to balance the page to the bottom margin.  This
-behaviour can be changed with the control macro
-<a href="#ALWAYS_FULLSPACE_QUOTES">ALWAYS_FULLSPACE_QUOTES</a>.
-<p>
-<strong>NOTE:</strong> <strong>ALWAYS_FULLSPACE_QUOTES</strong>
-applies to both
-<a href="#QUOTE">QUOTE</a>
-and
-<a href="#BLOCKQUOTE">BLOCKQUOTE</a>,
-as does the control macro
-<a href="#QUOTE_INDENT">QUOTE_INDENT</a>.
-<p>
-<strong>Version 1.3: mom</strong>'s handling of the vertical
-whitespace around quotes has changed slightly.  In versions prior
-to 1.3, it was not possible to alter the
-<a href="definitions.html#TERMS_LEADING">leading</a>
-of quotes and blockquotes (which was the same as the document
-leading), ensuring that the vertical whitespace remained consistent,
-as described above.  In 1.3 and later, it is possible to change the
-leading of quotes and blockquote via
-the <strong>QUOTE_AUTOLEAD</strong> and
-<strong>BLOCKQUOTE_AUTOLEAD</strong>macro.  Now, if your quote
-(or blockquote) leading differs from the document leading,
-<strong>mom</strong> attempts to observe the same rules for vertical
-whitespace outlined above; however, she will also insert a small,
-flexible amount of extra whitespace around the quotes to make sure
-the whitespace is equal, top and bottom.  Since she does this on a
-quote by quote basis, rather than by figuring out how much extra
-whitespace is needed to adjust <em>all</em> quotes on a page,
-the spacing around multiple quotes on the same page will differ
-slightly, although each will be balanced between lines of normal
-<a href="definitions.html#TERMS_RUNNING">running text</a>,
-top and bottom.  (The inability to scan an entire page and insert
-equalized whitespace at marked places is a limitation of groff,
-which, by and large, works in a linear, line by line fashion.)
-If you don't provide <strong>mom</strong> with a
-<strong>QUOTE_AUTOLEAD</strong>, quotes are leaded at the default
-for normal running text, meaning that multiple quotes on the same
-page are all spaced identically.
-<p>
-<a name="QUOTE_TIP"><strong>TIP:</strong></a>
-If you want to include snippets of programming code in
-<strong>mom</strong> documents, you may come acropper of the fact
-that groff (and <strong>mom</strong>'s) escape character is the
-backslash.  In order for <strong>mom</strong> not to interpret
-backslashes that occur in code snippets as escapes, you have to
-tell <strong>mom</strong> that the backslash character is
-(temporarily) no longer the escape character.  The easiest way
-to do this is to set the escape character to something else for
-the duration of the code snippet.  You accomplish this with
-<strong>ESC_CHAR</strong>, like this:
-<p>
-<pre>
-	.ESC_CHAR c
-</pre>
-
-where &quot;c&quot;, above, is the alternate escape character
-(which should be a character that does not appear in the code).  To
-set the escape character back to the backslash, simply invoke
-<strong>.ESC_CHAR</strong> by itself (i.e. with no argument).
-<p>
-Because <strong>mom</strong>, by default, sets the text after
-<strong>.QUOTE</strong> in italic (for <strong>PRINTSTYLE
-TYPESET</strong>) or underlined (for <strong>PRINTSTYLE
-TYPEWRITE</strong>), you'll want to change that behaviour as
-well.  Therefore, a recipe for setting verbatim code snippets using
-<strong>QUOTE</strong> could be (assuming you want a fixed width
-font like Courier):
-<p>
-<pre>
-	\# You only need the first two lines before the first invocation
-	\# of QUOTE.  They stay in effect for all subsequent invocations.
-	\#
-	.QUOTE_FONT       CR    \" Set quote font to Courier roman
-	.UNDERLINE_QUOTES OFF   \" Don't underline quotes in TYPEWRITE
-	.QUOTE
-	.ESC_CHAR ^             \" Change escape character to ^
-	&lt;code snippet&gt;
-	.ESC_CHAR               \" Restore escape character to \

-<p>
-Lists are points or items of interest or importance that are
-separated from
-<a href="definitions.html#TERMS_RUNNING">running text</a>
-by enumerators.  Some typical enumerators are
-<a href="definitions.html#TERMS_EM">en-dashes</a>,
-<a href="definitions.html#TERMS_BULLET">bullets</a>,
-digits and letters.
-<p>
-Setting lists with <strong>mom</strong> is easy.  First, you
-initialize a list with the <strong>LIST</strong> macro.  Then, for
-every item in the list, you invoke the macro, <strong>ITEM</strong>,
-followed by the text of the item.  When a list is finished, you
-exit the list with <strong>LIST OFF</strong> (or
-<strong>QUIT</strong>, <strong>END</strong>, <strong>BACK</strong>,
-etc.)
-<p>
-By default <strong>mom</strong> starts each list with the enumerator
-flush with the left margin of running text that comes before it,
-like this:
-<p>
-<pre>
-	My daily schedule needs organizing.  I can't
-	seem to get everything done I want.
-	o an hour's worth of exercise
-	o time to prepare at least one healthy
-	  meal per day
-	o reading time
-	o work on mom
-	o writing
-	  - changes from publisher
-	  - current novel
-	o a couple of hours at the piano
-</pre>
-
-In other words, <strong>mom</strong> does not, by default, indent
-entire lists.  Indenting a list is controlled by the macro,
-<a href="#SHIFT_LIST">SHIFT_LIST</a>.
-(This is a design decision; there are too many instances where a
-default indent is not desirable.)  Equally, <strong>mom</strong>
-does not add any extra space above or below lists.
-<p>
-Lists can be nested (as in the example above).  In other words, you
-can set lists within lists, each with an enumerator (and possibly,
-indent) of your choosing.  In nested lists, each invocation of
-<strong>LIST OFF</strong> (you may prefer to use <strong>LIST
-BACK</strong>) takes you back to the previous depth (or
-level) of list, with that list's enumerator and indent intact.  The
-final <strong>LIST OFF</strong> exits lists completely and returns
-you to the left margin of running text.
-<p>
-Finally, lists can be used in documents created with either the
-document processing macros or just the typesetting macros.

-<p>
-<strong>NOTE:</strong> Every time you invoke <strong>LIST</strong>

-stores the enumerator, separator and indent for any list you return
-<em>backwards</em> to (i.e. with <strong>LIST OFF</strong>), but
-does not store any information for lists you move <em>forward</em>

-
-<h3><u>The first argument--enumerator style</u></h3>
-<p>
-The optional arguments <strong>BULLET</strong>,
-<strong>DASH</strong>, <strong>DIGIT</strong> (for
-Arabic numerals), <strong>ALPHA</strong> (for uppercase
-letters), <strong>alpha</strong> (for lowercase letters),
-<strong>ROMAN&lt;n&gt;</strong> (for uppercase roman numerals),
-<strong>roman&lt;n&gt;</strong> (for lowercase roman numerals) tell
-<strong>mom</strong> what kind of enumerator to use for a given
-list.
-<p>
-The arguments, <strong>ROMAN&lt;n&gt;</strong> and
-<strong>roman&lt;n&gt;</strong>, are special.  You must append to
-them a digit (arabic, e.g.  "1" or "9" or "17") saying how many items
-a particular roman-numeralled <strong>LIST</strong> is going to
-have. <strong>Mom</strong> requires this information in order to
-align roman numerals sensibly, and will abort--with a message--if
-you don't provide it.
-<p>
-A roman-numeralled list containing, say, five items, would be set
-up like this:
-<p>
-<pre>
-	.LIST roman5        producing        i)   Item 1.
-	.ITEM                                ii)  Item 2.
-	Item 1.                              iii) Item 3.
-	.ITEM                                iv)  Item 4.
-	Item 2.                              v)   Item 5.
-	.ITEM
-	Item 3
-	.ITEM
-	Item 4
-	.ITEM
-	Item 5
-</pre>
-
-<p>
-The argument, <strong>USER</strong>, lets you make up your own
-enumerator, and must be followed by a second argument: what you'd
-like the enumerator to look like.  For example, if you want a list
-enumerated with
-<strong>=&gt;</strong>,
-<p>
-<pre>
-	.LIST USER =&gt;
-	.ITEM
-	A list item
-</pre>
-
-will produce
-<p>
-<pre>
-	=&gt; A list item
-</pre>
-
-<strong>Please note:</strong> if the argument to
-<strong>USER</strong> contains spaces, you must enclose the argument
-in double quotes.
-
-<br>
-
-<h3><u>The second argument--separator style</u></h3>
-<p>
-If you choose <strong>DIGIT</strong>, <strong>ALPHA</strong>,
-<strong>alpha</strong>, <strong>ROMAN&lt;n&gt;</strong>, or
-<strong>roman&lt;n&gt;</strong>, you may enter the optional
-argument, <strong>separator</strong>, to say what kind of separator
-you want after the enumerator.  The separator can be anything you
-like.  The default for <strong>DIGIT</strong> is a period (dot),
-like this:
-<p>
-<pre>
-	1. A list item
-</pre>
-
-The default separator for <strong>ALPHA</strong>,
-<strong>alpha</strong>, <strong>ROMAN&lt;n&gt;</strong> and
-<strong>roman&lt;n&gt;</strong> is a right parenthesis, like this:
-<p>
-<pre>
-	a) An alpha-ed list item
-	b) A second alpha-ed list item
-
-	   or
-
-	i)  A roman-ed list item
-	ii) A second roman-ed item
-</pre>
-
-If you'd prefer, say, digits with right-parenthesis separators
-instead of the default period, you'd do
-<p>
-<pre>
-	.LIST DIGIT )
-	.ITEM
-	A numberd list item
-</pre>
-
-which would produce
-<p>
-<pre>
-	1) A numbered list item
-</pre>
-
-<strong>Please note: BULLET</strong>, <strong>DASH</strong> and
-<strong>USER</strong> do not take a separator.
-<br>
-
-<h3><u>The third argument--prefix style</u></h3>
-<p>
-Additionally, you may give a prefix (i.e. a character that comes
-<em>before</em> the enumerator) when your enumerator style for a
-particular list is <strong>DIGIT</strong>, <strong>ALPHA</strong>,
-<strong>alpha</strong>, <strong>ROMAN&lt;n&gt;</strong>
-or <strong>roman&lt;n&gt;</strong>.  In the arguments to
-<strong>LIST</strong>, the prefix comes <em>after</em> the
-separator, which may seem counter-intuitive, so please be careful.
-<p>
-A prefix can be anything you like.  Most likely, you'll want some
-kind of open-bracket, such as a left parenthesis.  If, for example,
-you want a <strong>DIGIT</strong> list with the numbers enclosed in
-parentheses, you'd enter
-<p>
-<pre>
-	.LIST DIGIT ) (
-	.ITEM
-	The first item on the list.
-	.ITEM
-	The second item on the list.

-<a name="RESET_LIST"><h3><u>2. Resetting an initialized list's enumerator -- RESET_LIST</u></h3></a>
-<p>
-In nested lists, if your choice of list enumerator for a given
-level of list is <strong>DIGIT</strong>, <strong>ALPHA</strong>,
-<strong>alpha</strong>, <strong>ROMAN</strong> or
-<strong>roman</strong>, you may sometimes want to reset the list's
-enumerator when you return to that list.  Consider the following:
-<p>
-<pre>
-	Things to do religiously each and every day:
-	1. Take care of the dog
-	   a) walk every day
-	   b) brush once a week
-	      - trim around the eyes every fourth brushing
-	      - don't forget to check nails
-	2. Feed the cat
-	   a) soft food on Mon., Wed. and Fri.
-	   b) dry food on Tues., Thurs. and Sat.
-	   c) canned tuna on Sunday
-</pre>
-
-Normally, within a nested list, when you return to an
-incrementally-enumerated list, the enumerator continues incrementing
-from where it left off.  That means, in the example above, the
-normal state of affairs for the alpha'ed list under &quot;2.  Feed
-the cat&quot; would be c), d) and e).  The solution, in such a case,
-is simply to reset the enumerator --before <strong>ITEM</strong>!--
-with the macro, <strong>RESET_LIST</strong>.
-<p>
-By default, with no argument, <strong>RESET_LIST</strong> resets the
-enumerator to 1, A, a, I or i depending on the style of enumerator.
-You may, if you wish, pass <strong>RESET_LISTS</strong> a numeric
-argument representing the starting enumerator for the reset (if
-different from "1"), although I can't at present think of a use for
-this feature.
-<p>
-<a name="PAD_LIST_DIGITS"><h3><u>3. Padding digit enumerators (PAD_LIST_DIGITS)</a></u></h3></a>
-<p>
-<strong><u>Arabic digits</u></strong>
-<p>
-When your choice of enumerators is <strong>DIGIT</strong> AND the
-number of items in the list exceeds nine (9), you have to make a
-design decision: should <strong>mom</strong> leave room for the
-extra numeral in two-numeral digits to the right or the left of
-the single-numeral digits?
-<p>
-If you want the extra space to the right, invoke the macro,
-<strong>.PAD_LIST_DIGITS</strong> (with no argument), after
-<strong>LIST</strong> and before <strong>ITEM</strong>.  This will
-produce something like
-<p>
-<pre>
-	8.  List item
-	9.  List item
-	10. List item
-</pre>
-
-If you want the extra space to the left, invoke
-<strong>PAD_LIST_DIGITS</strong> with the single argument,
-<strong>LEFT</strong>, which will produce
-<p>
-<pre>
-	 8. List item
-	 9. List item
-	10. List item
-</pre>
-
-Of course, if the number of items in the list is less than ten
-(10), there's no need for <strong>PAD_LIST_DIGITS</strong>.
-<p>
-<strong><u>Roman numerals</u></strong>
-<p>
-By default, <strong>mom</strong> sets roman numerals in lists flush
-left.  The <strong>&lt;n&gt;</strong> argument appended to
-<strong>ROMAN&lt;n&gt;</strong> or <strong>roman&lt;n&gt;</strong>
-allows her to calculate how much space to put after each numeral in
-order to ensure that the text of items lines up properly.
-<p>
-If you'd like the roman numerals to line up flush right (i.e. be
-padded "left"), simply invoke <strong>PAD_LIST_DIGITS</strong>
-<kbd>LEFT</kbd> after <strong>LIST</strong> <kbd>ROMAN&lt;n&gt;</kbd>
-or <strong>LIST</strong> <kbd>roman&lt;n&gt;</kbd> amd before

-<strong>Mom</strong>'s line-numbering capabilities are not as flexible

-that groff's underlying line-numbering
-<a href="definitions.html#TERMS_PRIMITIVEX">primitive</a>,

-<strong>NUMBER_LINES</strong> does what it says: prints line
-numbers, to the left of
-<a href="definitions.html#TERMS_OUTPUTLINE">output lines</a>
-of paragraph text.  One of the chief reasons for wanting numbered
-lines is in order to identify footnotes or endnotes by line number
-instead of by a marker in the text.  (See
-<a href="#FOOTNOTE_LINENUMBERS">.FOOTNOTE_MARKER_STYLE LINE</a>
-for instructions on line-numbered footnotes, and
-<a href="#ENDNOTE_MARKER_STYLE">.ENDNOTE_MARKER_STYLE</a>
-for instructions on line-numbered endnotes.)
-<p>
-Every time you invoke <strong>NUMBER_LINES</strong>, unless you are
-using the arguments <strong>OFF</strong> (<strong>QUIT</strong>,
-<strong>END</strong>, <strong>X</strong>, etc.) or
-<strong>RESUME</strong> you must, at a minimum, pass it one
-argument, namely the number (digit) you want the <em>next</em>
-<a href="definitions.html#TERMS_OUTPUTLINE">output line</a>
-to have.  For example,
-<pre>
-	.NUMBER_LINES 3
-</pre>
-
-will prepend the number, 3, to the next output line.
-<p>
-Normally, of course, you will number lines of text starting at 1.
-All you have to do in that case is ensure that
-<pre>
-	.NUMBER_LINES 1
-</pre>
-
-precedes your first line of input text, which will also be the
-first line of output text.
-<p>
-You can alter <strong>mom</strong>'s default line numbering
-behaviour (see
-<a href="#NUMBER_LINES_DEFAULT">above</a>)
-with the optional arguments <strong>&lt;which lines to
-number&gt;</strong> and <strong>&lt;gutter&gt;</strong>.
-<p>
-<strong>&lt;which lines to number&gt;</strong> instructs
-<strong>NUMBER_LINES</strong> to number only certain lines, e.g.
-every two lines or every five lines.  If you want, say, only every
-five lines to have a prepended number, you'd do
-<pre>
-	.NUMBER_LINES 1 5
-</pre>
-
-<strong>GOTCHA!</strong>  The argument to <strong>&lt;which
-lines to number&gt;</strong> only numbers those lines that are
-multiples of the argument.  Hence, in the above example, line
-number "1" will <em>not</em> be numbered, since "1" is not a
-multiple of "5".
-<p>
-If you wanted line number "1" to be numbered, you'd have to invoke
-<kbd>.NUMBER_LINES 1 1</kbd> before the first output line, then
-study your <em>output</em> copy and determine where best to insert
-the following in your <em>input</em> copy:
-<pre>
-	.NUMBER_LINES \n(ln 5
-</pre>
-
-(The escape, <kbd>\n(ln</kbd>, ensures that
-<strong>NUMBER_LINES</strong> automatically supplies the correct
-value for the first argument, <strong>&lt;start
-number&gt;</strong>.)
-<p>
-Following this recipe, line number 1 will be numbered; subsequently,
-only line numbers that are multiples of 5 will be numbered.  A
-little experimentation may be required to determine the best place
-for it.
-<p>
-The optional argument, <strong>&lt;gutter&gt;</strong>, tells
-<strong>mom</strong> how much space to put between the line numbers
-and the running text.
-<p>
-<strong>Note</strong>: when giving a value for
-<strong>&lt;gutter&gt;</strong>, you cannot skip the
-<strong>&lt;which lines to number&gt;</strong> argument.  Either
-fill in the desired value, or use two double-quotes
-(<strong>""</strong>) to have <strong>mom</strong> use the value
-formerly in effect.
-<p>
-<strong>&lt;gutter&gt;</strong> does not require (or even accept) a
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>.
-The argument you pass to it is the number of
-<a href="definitions.html#TERMS_FIGURESPACE">figure spaces</a>
-you want between line numbers and running text.
-<strong>Mom</strong>'s default gutter is two figure spaces.  If
-you'd like a wider gutter, say, four figures spaces, you'd do
-<pre>
-	.NUMBER_LINES 1 1 4
-	                |
-	                +-- Notice you *must* supply a value
-	                    for the 2nd argument in order to supply
-	                    a value for the 3rd.
-</pre>
-
-<p>
-After you've set up line-numbering, <strong>NUMBER_LINES</strong>
-can be used to control line numbering.
-<br>
-<h3><u>Line-numbering control</u></h3>
-<p>
-<strong>NUMBER_LINES OFF</strong> (or <strong>END, QUIT, X,</strong> etc.)
-turns line-numbering off.
-<p>
-Sometimes, you merely want to suspend line-numbering.  In that case,
-turn line numbering off with <strong>NUMBER_LINES OFF</strong>.
-Later, when you want it to resume, enter
-<pre>
-	.NUMBER_LINES RESUME
-</pre>
-
-Line numbering will resume exactly where it left off.  If this is
-not what you want--say you want to reset the line number to "1"--simply
-invoke <strong>NUMBER_LINES</strong> with whatever arguments
-are needed for the desired result.
-<p>
-<strong>Extra Notes:</strong>
-<br>
-<ol>
-    <li>In document processing, you may invoke <strong>NUMBER_LINES</strong>
-        either before or after <strong>START</strong>.
-        <strong>Mom</strong> doesn't care.
-    <li>If you're collating documents with
-        <a href="rectoverso.html#COLLATE">COLLATE</a>,
-        you should re-invoke, at a minimum, <kbd>.NUMBER_LINES
-        1</kbd> for each collated document, in order to ensure that
-        each begins with the number "1" prepended to the first line
-        (unless, of course, that is not what you want).
-    <li>Occasionally, you may want to change the current gutter
-        between line numbers and running text without knowing
-        what the next output line number should be.  Since
-        <strong>NUMBER_LINES</strong> requires this number
-        as its first argument, in such instances, pass
-        <strong>NUMBER_LINES</strong> as its first argument the
-        escape <kbd>\n(ln</kbd>.
-        <p>
-        For example, if you were numbering every 5 lines with a
-        gutter of 2 (figure spaces) and you needed to change the
-        gutter to 4 (figures spaces),
-        <p>
-        <kbd>&nbsp;&nbsp;&nbsp;&nbsp;.NUMBER_LINES \n(ln 5 4</kbd>
-        <p>
-        would do the trick.
-    <li>If you're using margin notes in a document, be sure to set
-        the gutter for margin notes wide enough to allow room for
-        the line numbers.
-    <li><strong>Mom</strong> (groff, actually), only numbers lines
-        <em>to the left of text</em>.  For aesthetic reason,
-        therefore, the use of line numbering when setting a document
-        in columns is discouraged.  However, should you wish to
-        number lines when setting in columns, make sure the
-        <a href="definitions.html#TERMS_GUTTER">gutter(s)</a>
-        between columns is wide enough to leave room for the
-        numbers.

-behaviour of <em>suspending</em> incrementing of line numbers during
-the output of blockquotes.)  This allows you to embed line-numbered
-footnotes inside blockquotes and have the line number "label" in the
-footnote come out sensibly.
-<p>
-Once having turned <strong>NUMBER_BLOCKQUOTE_LINES</strong> on, you
-may disable it with <strong>NUMBER_BLOCKQUOTE_LINES OFF</strong> (or
-<strong>QUIT</strong>, <strong>END</strong>, <strong>X</strong>,
-etc).
-<p>
-
-<a name="NUMBER_LINES_QUOTES"><h3><u>3. Setting up line numbering in quotes and blockquotes on a case by case basis</u></h3></a>
-<p>
-Sometimes, you may want quotes or blockquotes to have a different
-line numbering scheme from the one used in the rest of the
-document.  Or, you may want line numbering enabled only inside a
-particular quote or blockquote.  A common reason for this would be
-if you were using the
-<a href="#QUOTE">QUOTE</a>
-macro to insert lines of programming code into a document.  (See
-<a href="#QUOTE_TIP">here</a>
-for suggestions about including programming code snippets in
-documents.)
-<p>
-To enable line numbering within quotes or blockquotes on a case by
-case basis, simply invoke <strong>NUMBER_LINES</strong>, with the
-arguments you need, immediately after entering <strong>QUOTE</strong>
-or <strong>BLOCKQUOTE</strong>.  (<strong>NUMBER_QUOTE_LINES</strong>
-and/or <strong>NUMBER_BLOCKQUOTE_LINES</strong> should be turned
-off if you're doing this.)  The quote or blockquote will then be
-line-numbered according to your specifications: the starting line
-number of the quote or blockquote will be the one you give as a
-first argument to <strong>NUMBER_LINES</strong>; which lines to
-number will be the value you pass to <strong>&lt;which lines to
-number&gt;</strong> (defaults to "1"); line numbers will hang
-to the left of the quote or blockquote, separated from the quote or
-blockquote by <strong>&lt;gutter&gt;</strong> (defaults to "2").
-<p>
-As soon as <strong>QUOTE</strong> or <strong>BLOCKQUOTE</strong> is
-turned off, line numbering ceases, not only with respect to
-subsequent paragraph text (if they are not being line-numbered),
-but also for any subsequent invocation of <strong>QUOTE</strong> or
-<strong>BLOCKQUOTE</strong>.  In other words, you must re-enable
-quote or blockquote line-numbering inside every instance of
-<strong>QUOTE</strong> or <strong>BLOCKQUOTE</strong> when
-line-numbering either of them on a case by case basis.

-For something so complex behind the scenes, footnotes are easy to use.
-You just type, for example

-<pre>
-	...the doctrines of Identity as urged by Schelling\c

-<p>
-(Note the obligatory use of the <strong>\c</strong>
-<a href="definitions.html#TERMS_INLINES">inline escape</a>.
-It is required when your

-<strong>LINE</strong>, or when footnote markers have been disabled
-with
-<a href="#FOOTNOTE_MARKERS">.FOOTNOTE_MARKERS</a>
-<strong>OFF</strong>.)
-<p>
-<strong>***Version 1.3 change***</strong>
-<p>
-As of version 1.3, the manner of entering the line
-<em>after</em> <strong>.FOOTNOTE OFF</strong> has changed
-to accommodate users' differing wishes with respect to
-the order of punctuation and footnote markers.  The
-correct way to enter the line after <strong>.FOOTNOTE
-OFF</strong>--<strong><em><u>ONLY</u></em></strong> if your
-<a href="#FOOTNOTE_MARKER_STYLE">FOOTNOTE_MARKER_STYLE</a> is
-<strong>STAR</strong> or <strong>NUMBER</strong>--is to input
-it as if it's literally a continuation of the line before
-<strong>.FOOTNOTE</strong>, and therefore begins with either a space
-or a punctuation mark, as in the two following examples.
-<p>
-<pre>
-	   Example 1					  Example 2
-	   ---------                      ---------
-

-	 broken up with a comma.		, broken up with a comma.
-
-	(last line begins with			(last line begins with
-	 a literal space)				 the comma and a space)
-</pre>
-
-If your <strong>FOOTNOTE_MARKER_STYLE</strong> is line, none of
-this is a concern.
-<p>
-<strong>***End of version 1.3 change***</strong>
-<p>
-After you invoke <strong>FOOTNOTE</strong>, <strong>mom</strong>
-takes care of everything: putting footnote markers in the body of
-the document, keeping track of how many footnotes are on the page,
-identifying the footnotes themselves appropriately, balancing them
-properly with the bottom margin, deferring footnotes that don't fit
-on the page...  Even if you're using
-<a href="columns.html#COLUMNS">COLUMNS</a>,
-<strong>mom</strong> knows what to do, and Does The Right Thing.
-<p>
-Footnotes can be sly little beasts, though.  If you're writing a
-document that's footnote-heavy, you might want to read the following.
-<p>
-
-<a name="FOOTNOTE_BEHAVIOUR"><h3><u>Footnote behaviour</u></h3></a>
-<p>
-By default, <strong>mom</strong> marks footnotes with alternating
-stars (asterisks), daggers, and double-daggers.  The first footnote
-gets a star, the second a dagger, the third a double-dagger, the
-fourth two stars, the fifth two daggers, etc.  If you prefer
-numbered footnotes, rest assured <strong>mom</strong> is happy to
-oblige.
-<p>
-A small amount of vertical whitespace and a short horizontal rule
-separate footnotes from the document body.  The amount of whitespace
-varies slightly from page to page depending on the number of lines
-in the footnotes. <strong>Mom</strong> tries for a nice balance
-between too little whitespace and too much, but when push comes to
-shove, she'll usually opt for ample over cramped.  The last lines of
-footnotes are always flush with the document's bottom margin.
-<a name="FOOTNOTE_RULES"></a>
-<p>
-If <strong>mom</strong> sees that a portion of a footnote cannot
-be fit on its page, she carries that portion over to the next
-page.  If an entire footnote can't be fit on its page (i.e.
-<strong>FOOTNOTE</strong> has been called too close to the bottom),
-she defers the footnote to the next page, but sets it with the
-appropriate marker from the previous page.
-<p>
-When footnotes occur within cited text, for example a
-<a href="#QUOTE">QUOTE</a>
-or a
-<a href="#BLOCKQUOTE">BLOCKQUOTE</a>,
-<strong>mom</strong> will usually opt for deferring the footnote
-over to the next page if it allows her to complete the cited text
-on one page.
-<p>
-In the unfortunate happenstance that a deferred footnote is the
-only footnote on its page (i.e. it's marked in the document body with
-a star) and the page it's deferred to has its own footnotes,
-<strong>mom</strong> separates the deferred footnote from the page's
-proper footnote(s) with a blank line.  This avoids the confusion that
-might result from readers seeing two footnote entries on the same page
-identified by a single star (or the number 1 if you've requested
-numbered footnotes that begin at 1 on every page).  The blank line
-makes it clear that the first footnote entry belongs to the previous
-page.
-<p>
-In the circumstance where a deferred footnote is not the only one
-on its page, and is consequently marked by something other than a
-single star, there's no confusion and <strong>mom</strong> doesn't
-bother with the blank line.  (By convention, the first footnote on
-a page is always marked with a single star, so if readers see, say,
-a dagger or double-dagger marking the first footnote entry, they'll
-know the entry belongs to the previous page).
-<p>
-Very exceptionally, two footnotes may have to be deferred (e.g. one
-occurs on the second to last line of a page, and another on the
-last line).  In such a circumstance, <strong>mom</strong> does not
-add a blank after the second deferred footnote.  If you'd like a
-blank line separating both deferred footnotes from any footnotes
-proper to the page the deferred ones were moved to, add the space
-manually by putting a 
-<a href="typesetting.html#SPACE">.SPACE</a>
-command at the end of the footnote text, before
-<strong>FOOTNOTE OFF</strong> (or <strong>FOOTNOTE X, QUIT,
-EXIT, etc...</strong>).
-<p>
-Obviously, deferred footnotes aren't an issue if you request numbered
-footnotes that increase incrementally throughout the whole document --
-yet another convenience <strong>mom</strong> has thought of.
-<p>
-While <strong>mom</strong>'s handling of footnotes is
-sophisticated, and tries to take nearly every imaginable situation
-under which they might occur into account, some situations are
-simply impossible from a typographic standpoint.  For example, if
-you have a
-<a href="#HEAD">HEAD</a>
-near the bottom of the page AND that page has some footnotes on it,
-<strong>mom</strong> may simply not have room to set any text under
-the head (normally, she insists on having room for at least one line
-of text beneath a head).  In such an instance, <strong>mom</strong>
-will either set the head, with nothing under it but footnotes,
-or transfer the head to the next page.  Either way, you'll have a
-gaping hole at the bottom of the page.  It's a sort of typographic
-Catch-22, and can only be resolved by you, the writer or formatter
-of the document, adjusting the type on the offending page so as to
-circumvent the problem.
-<p>
-<strong>NOTE:</strong> Exceptionally, you may encounter problems with footnotes inside
-quotes and blockquotes that cross a page or column.  See <a
-href="#BREAK_QUOTE">BREAK_QUOTE</a>
-for a solution.
-<p>
-
-<h3><u><a name="FN_AND_PUNCT">Footnote markers and punctuation in the running text</a></u></h3>
-
-<p>
-As of version 1.3, the manner of entering the line <em>after</em>
-<strong>.FOOTNOTE OFF</strong> has changed.  The correct way to
-enter the line after <strong>.FOOTNOTE OFF</strong> now is to
-input it as if it's literally a continuation of the line before
-<strong>.FOOTNOTE</strong>, and therefore begins with either a space
-or a punctuation mark, as in the two following examples.
-<p>
-<pre>
-	   Example 1					  Example 2
-	   ---------                      ---------
-

-	 broken up with a comma.		, broken up with a comma.
-
-	(last line begins with			(last line begins with
-	 a literal space)				 the comma and a space)
-</pre>
-
-Care must be taken, though, if the punctuation mark that begins the
-line after <strong>FOOTNOTE OFF</strong> is a period (dot).  You
-<strong><em><u>must</u></em></strong> begin such lines with
-<strong>\&.</strong>, like this:
-<p>
-<pre>
-	end of a sentence\c
-	.FOOTNOTE
-	A footnote line.
-	.FOOTNOTE OFF
-	\&.  A new sentence...
-</pre>
-
-If you omit the <strong>\&.</strong>, the line will vanish!

-<strong>FOOTNOTE</strong> is a toggle macro, therefore invoking it

-<p>
-
-<a name="FOOTNOTE_MARKER_STYLE"><h3><u>3. Footnote marker style -- FOOTNOTE_MARKER_STYLE</u></h3></a>
-<p>
-<strong>Mom</strong> gives you two choices of footnote marker style:
-star+dagger (see 
-<a href="#FOOTNOTE_BEHAVIOUR">footnote behaviour</a>
-above), or numbered.
-<p>
-<strong>.FOOTNOTE_MARKER_STYLE STAR</strong> gives you star+dagger
-(the default).  There is a limit of 10 footnotes per page with
-this style.
-<p>
-<strong>.FOOTNOTE_MARKER_STYLE NUMBER</strong> gives you superscript
-numbers, both in the document body and in the footnote entries
-themselves.  By default, footnote numbers increase incrementally
-(prev. footnote number + 1) throughout the whole document.  You can
-ask <strong>mom</strong> to start each page's footnote numbers at 1
-with <strong>.RESET_FOOTNOTE_NUMBER</strong>
-(<a href="#RESET_FOOTNOTE_NUMBER">see below</a>.)
-<a name="FOOTNOTE_LINENUMBERS"><p></a>
-<p>
-<strong>.FOOTNOTE_MARKER_STYLE LINE</strong> lets you have
-footnotes which are identified by line number, rather than by a
-marker in the text.  (Note that
-<a href="#NUMBER_LINES">NUMBER_LINES</a>
-must be enabled in order to use this marker style.)
-<p>
-With <strong>FOOTNOTE_MARKER_STYLE LINE</strong>, <strong>mom</strong>
-will identify footnotes either by single line numbers, or line
-ranges.  If what you want is a single line number, you need only
-invoke <strong>.FOOTNOTE</strong>, <em>without terminating the text
-line before it with</em> <strong>\c</strong>, at the appropriate
-place in running text.
-<p>
-If you want a range of line numbers (e.g.&nbsp;[5-11]&nbsp;),
-insert, directly into the first line of the range you want, the
-<a href="definitions.html#TERMS_INLINES">inline escape</a>,
-<strong>\*[FN-MARK]</strong>.  For the terminating line number of
-the range, you need only invoke <strong>.FOOTNOTE</strong>, (again,
-without attaching <strong>\c</strong> to the text line before it).
-<strong>Mom</strong> is smart enough to figure out that where
-<strong>FOOTNOTE</strong> was invoked represents the terminating
-line number.  Range-numbered footnotes are always output on the page
-where <strong>FOOTNOTE</strong> was invoked, not the page where
-<strong>\*[FN-MARK]</strong> appears (subject, of course, to the
-rules for footnotes that fall too close to the bottom of a page, as
-outlined
-<a href="#FOOTNOTE_RULES">here</a>).
-<a name="FOOTNOTE_LINENUMBER_BRACKETS"></a>
-<p>
-<strong>Mom</strong>, by default, puts footnote line numbers inside
-square brackets.  The style of the brackets may be changed with
-the macro, <strong>FOOTNOTE_LINENUMBER_BRACKETS</strong>, which
-takes one of three possible arguments: <strong>PARENS</strong>
-("round" brackets), <strong>SQUARE</strong> (the default) or
-<strong>BRACES</strong> (curly braces).  If you prefer a
-shortform, the arguments, <strong>(</strong>, <strong>[</strong> or
-<strong>{</strong> may be used instead.
-<a name="FOOTNOTE_LINENUMBER_SEPARATOR"></a>
-<p>
-If you don't want the numbers enclosed in brackets, you may tell
-<strong>mom</strong> to use a "separator" instead.  A common
-separator would be the colon, but it can be anything you like.  The
-macro to do this is <strong>FOOTNOTE_LINENUMBER_SEPARATOR</strong>,
-which takes, as its single argument, the separator you want.  For
-safety and consistency's sake, ALWAYS enclose the argument in
-double-quotes.
-<p>
-The separator can be composed of any legal groff character, or any
-combination of characters. <strong>A word of caution:</strong> when
-using a separator, <strong>mom</strong> doesn't insert a space
-after the separator.  Hence, if you want the space (you probably
-do), you must make the space part of the argument you pass to
-<strong>FOOTNOTE_LINENUMBER_SEPARATOR</strong>.  For example,
-to get a colon separator with a space after it, you'd do
-<p>
-<pre>
-	.FOOTNOTE_LINENUMBER_SEPARATOR ": "
-</pre>
-
-<a name="FOOTNOTES_RUN_ON"><strong><u>RUN-ON FOOTNOTES</u></strong></a>
-<p>
-Finally, if your footnote marker style is <strong>LINE</strong>, you
-may instruct <strong>mom</strong> to do "run-on style" footnotes.
-Run-on footnotes do not treat footnotes as discrete entities, i.e.
-on a line by themselves.  Rather, each footnote is separated from
-the footnote before it by a space, so that the footnotes on any
-given page form a continuous block, like lines in a paragraph.  The
-macro to get
-<strong>mom</strong> to run footnotes on is
-<strong>.FOOTNOTES_RUN_ON</strong>.  Invoked by itself, it turns
-the feature on.  Invoked with any other argument
-(<strong>OFF</strong>, <strong>NO</strong>, etc.), it turns the
-feature off.  It is generally NOT a good idea to turn the feature
-on and off during the course of a single document.  If you do,
-<strong>mom</strong> will issue a warning if there's going to be a
-problem.  However, it is always perfectly safe to enable/disable the
-feature after
-<a href="rectoverso.html#COLLATE">COLLATE</a>.
-<p>
-The usual reason for wanting run-on footnotes is that you're
-using them to hold many, short references.  (See
-<a href="refer.html#TOP">here</a>
-for instructions on using the <strong>groff</strong> program,
-<strong>refer</strong>, to set up references.)
-
-<p>
-
-<a name="RESET_FOOTNOTE_NUMBER"><h3><u>4. Reset footnote number -- RESET_FOOTNOTE_NUMBER</u></h3></a>
-<p>
-<strong>.RESET_FOOTNOTE_NUMBER</strong>, by itself, resets
-footnote numbering so that the next footnote you enter is
-numbered 1.
-<p>
-<strong>.RESET_FOOTNOTE_NUMBER PAGE</strong> tells
-<strong>mom</strong> to start every page's footnote numbering at 1.
-<p>
-
-<a name="FOOTNOTE_SPACE"><h3><u>5. Inter-footnote spacing -- FOOTNOTE_SPACE</u></h3></a>
-<p>
-If you'd like a little extra space between footnotes, you can have
-<strong>mom</strong> put it in for you by invoking
-<strong>.FOOTNOTE_SPACE</strong> with an argument representing the
-amount of extra space you'd like.  The argument to
-<strong>FOOTNOTE_SPACE</strong> requires a
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>.
-<p>
-In the following example, footnotes will be separated from each
-other by 3
-<a href="definitions.html#TERMS_PICASPOINTS">points</a>.
-<pre>
-	.FOOTNOTE_SPACE 3p
-</pre>
-
-<a name="FOOTNOTE_RULE"><h3><u>6. Footnote rule -- FOOTNOTE_RULE</u></h3></a>
-<p>
-If you don't want a footnote separator rule, toggle it off with
-<strong>.FOOTNOTE_RULE OFF</strong> (or <strong>END,
-QUIT, X</strong>...).  Toggle it back on by invoking
-<strong>.FOOTNOTE_RULE</strong> with no argument.  The default is to
-print the rule.
-<p>
-
-<a name="FOOTNOTE_RULE_LENGTH"><h3><u>7. Footnote rule length -- FOOTNOTE_RULE_LENGTH</u></h3></a>
-<p>
-If you want to change the length of the footnote separator rule,
-invoke <strong>.FOOTNOTE_RULE_LENGTH</strong> with a length, like
-this,
-<pre>
-	.FOOTNOTE_RULE_LENGTH 1i
-</pre>
-
-which sets the length to 1 inch.  Note that a
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-is required.  The default is 4
-<a href="definitions.html#TERMS_PICASPOINTS">picas</a>
-for both
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLES</a>.
-<p>
-
-<a name="FOOTNOTE_RULE_ADJ"><h3><u>8. Adjust vertical position of footnote separator rule -- FOOTNOTE_RULE_ADJ</u></h3></a>
-<p>
-The footnote separator rule is actually a baseline rule that falls
-on the
-<a href="definitions.html#TERMS_BASELINE">baseline</a>
-of the first line of a page's footnotes.  By default,
-<strong>mom</strong> raises the rule 3
-<a href="definitions.html#TERMS_PICASPOINTS">points</a>
-from the baseline so that the separator and the footnotes don't
-look jammed together.  If you'd prefer a different vertical
-adjustment, invoke <strong>.FOOTNOTE_RULE_ADJ</strong> with the
-amount you'd like.  For example
-<p>
-<pre>
-	.FOOTNOTE_RULE_ADJ 4.25p
-</pre>
-
-raises the rule by 4-1/4 points.  Note that you can only raise
-the rule, not lower it.  A
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-is required.
-<p>
-<strong>Tip:</strong> If your document
-<a href="definitions.html#TERMS_LEADING">leading</a>
-is 2
-<a href="definitions.html#TERMS_PICASPOINTS">points</a>
-or less (e.g your
-<a href="definitions.html#TERMS_PS">point size</a>
-is 10 and your linespacing is 10, 11, or 12, lowering
-<strong>mom</strong>'s default footnote rule adjustment will
-almost certainly give you nicer looking results than leaving
-the adjustment at the default.  Furthermore, you can invoke
-<strong>FOOTNOTE_RULE_ADJ</strong> on any page in which footnotes
-appear, or in any column, so that the placement of the footnote rule
-can be changed on-the-fly, should you wish to do so.

-Embedding endnotes into <strong>mom</strong> documents is accomplished
-the same way as embedding
-<a href="#FOOTNOTE_INTRO">footnotes</a>.  The example below is
-identical to the one shown in the
-<a href="#FOOTNOTE_EXAMPLE">introduction to footnotes</a>,
-except that <kbd>.FOOTNOTE</kbd> has been replaced with

-<a href="definitions.html#TERMS_INLINES">inline escape</a>
-when your
-<a href="#ENDNOTE_MARKER_STYLE">ENDNOTE_MARKER_STYLE</a>
-is <strong>NUMBER</strong> (which marks endnotes references in

-with superscript numbers).  When the marker style is
-<strong>LINE</strong>, you must <em>not</em> use the
-<strong>\c</strong> escape.
-<p>
-<strong>***Version 1.3 change***</strong>
-<p>
-As of version 1.3, the manner of entering the line <em>after</em>
-<strong>.ENDNOTE OFF</strong> has changed to accommodate users'
-differing wishes with respect to the order of punctuation and
-endnote markers.  The correct way to enter the line after
-<strong>.ENDNOTE OFF</strong>--but <strong><em><u>NOT</u></em></strong>
-if your
-<a href="#ENDNOTE_MARKER_STYLE">ENDNOTE_MARKER_STYLE</a>
-is <strong>LINE</strong>--is to input it as if it's literally
-a continuation of the line before <strong>.ENDNOTE</strong>, and
-therefore begins with either a space or a punctuation mark, as in
-the two following examples.

-
-<strong>***End version 1.3 change***</strong>
-<p>
-Endnotes differ from footnotes in two ways (other than the fact that
-endnotes come at the end of a document whereas footnotes appear in the
-body of the document):
-<br>
-<ol>
-    <li>When your <strong>ENDNOTE_MARKER_STYLE</strong> is
-        <strong>NUMBER</strong>, endnotes are always numbered
-        incrementally, starting at "1".
-	<li>Endnotes MUST be output explicitly; <strong>mom</strong> does
-		not output them for you.  In
-		<a href="rectoverso.html#COLLATE">collated</a>
-		documents, this allows you to choose whether you
-		want the endnotes to appear at the end of each chapter or
-        article in a document, or grouped together at the very end
-        of the document.
-</ol>
-<p>
-Within endnotes, you may use the document element tags
-<a href="#PP">PP</a>,
-<a href="#QUOTE">QUOTE</a>
-and
-<a href="#BLOCKQUOTE">BLOCKQUOTE</a>.
-This provides the flexibility to create endnotes that run to several
-paragraphs, as well as to embed cited text within endnotes.
-<p>
-Should you wish to change the appearance of quotes or blockquotes that
-appear within endnotes, you may do so with the
-<a href="#QUOTE_CONTROL">quote control macros</a>
-or
-<a href="#BLOCKQUOTE_CONTROL">blockquote control macros</a>.
-HOWEVER... you must make the changes <em>within</em> each endnote, prior
-to invoking <strong>QUOTE</strong> or <strong>BLOCKQUOTE</strong>, and
-undo them prior to terminating the endnote (i.e. before <strong>ENDNOTE
-OFF</strong>), otherwise the changes will affect subsequent quotes and
-blockquotes that appear in the document body as well.
-<p>
-
-<a name="ENDNOTE_BEHAVIOUR"><h3><u>Endnote behaviour</u></h3></a>
-<br>
-When you output endnotes (with
-<a href="#ENDNOTES">ENDNOTES</a>),
-<strong>mom</strong> finishes processing the last page of your document,
-then breaks to a new page for printing the endnotes.  If the document
-type is
-<a href="docprocessing.html#DOCTYPE">CHAPTER</a>,
-the centre part of the
-<a href="definitions.html#TERMS_HEADER">header</a>
-(or footer), which, by default, contains a chapter number or title, is
-removed.
-<p>
-By default, <strong>mom</strong> starts the endnotes page with a
-bold, centred, double-underscored head, &quot;ENDNOTES&quot;.
-Underneath--flush left, bold, and underscored--she prints the document
-title (or, in the case of chapters, the chapter number or title).  She
-then prints the endnotes.  Each endnote is identified by its appropriate
-number, in bold, right aligned to two placeholders.  The text of the
-endnotes themselves is indented to the right of the numbers.
-<p>
-If the endnotes are grouped together at the end of a collated document,
-each section of the document that contains endnotes is identified by its
-own unique title (or chapter number or title), bold, flush left, and
-underscored.
-<p>
-Of course, all the defaults, as well as the overall style of the
-endnotes page, can be changed with the
-<a href="#ENDNOTE_CONTROL">endnote control macros</a>.
-The attentive will notice that endnotes have an awful lot of control
-macros.  This is because endnotes are like a mini-document unto
-themselves, and therefore need not be bound by the style parameters of
-the body of the document.
-<p>
-
-<a name="ENDNOTE_SPACING">
-	<h3><u>A Note on Endnote Spacing</u></h3>
-</a>
-<br>
-On the endnotes page(s), each new endnote is separated from the
-previous endnote by a full line space.  This can result in a bottom
-margin that hangs, and is the one instance, other than the use of
-<a href="#PP_SPACE">PARA_SPACE</a>,
-where <strong>mom</strong> allows unequal bottom alignment of pages.
-Should you wish to correct this, by adding or subtracting small amounts
-of space between endnotes that appear together on an endnotes page, make
-the adjustment (with
-<a href="typesetting.html#ALD">ALD</a>,
-<a href="typesetting.html#RLD">RLD</a>
-or
-<a href="typesetting.html#SPACE">SPACE</a>)

-<br>
-Formerly (pre 1.1.6), there was no way to set a document in columns
-(see

-you may now do so.  See

-<p>
-<strong>NOTE:</strong> If an endnote runs to more than one paragraph,

-the macro to do this.
-<p>
-Typically, you'll use <strong>ENDNOTES</strong> at the end of
-a document.  If it's a single (i.e. not collated) document,
-<strong>mom</strong> will print the endnotes pertaining to it.  If it's
-a collated document, <strong>mom</strong> will print all the endnotes

-appropriately identified and numbered.
-<p>
-Should you wish to output the endnotes for each section of a collated
-document at the ends of the sections (instead of at the very end of the
-document), simply invoke <strong>ENDNOTES</strong> immediately prior to
-<a href="rectoverso.html#COLLATE">COLLATE</a>.

-
-<a name="ENDNOTE_MARKER_STYLE"><h3><u>*Endnote marker style</u></h3></a>
-<p>
-The macro to control how endnotes are referenced is
-<strong>ENDNOTE_MARKER_STYLE</strong>.
-<p>
-By default, <strong>mom</strong> places superscript numbers in
-<a href="definitions.html#RUNNING">running text</a>
-to identify endnotes.  However, if you have
-<a href="#NUMBER_LINES">line-numbering</a>
-turned on, you may instruct <strong>mom</strong> not to put
-superscript numbers in the running text, but rather to reference
-endnotes by line number.  The command to do this is
-<p>
-<pre>
-	.ENDNOTE_MARKER_STYLE LINE
-</pre>
-
-With <strong>ENDNOTE_MARKER_STYLE LINE</strong>, <strong>mom</strong>
-will identify endnotes either by single line numbers, or line
-ranges.  If what you want is a single line number, you need only
-invoke <strong>.ENDNOTE</strong>, <em>without terminating the text
-line before it with</em> <strong>\c</strong>, at the appropriate
-place in running text.  (Should you wish to revert to
-<strong>mom</strong>'s default behaviour of placing a superscript
-number in the text to identify an endnote, you can invoke
-<strong>ENDNOTE_MARKER_STYLE</strong> with the argument,
-<strong>NUMBER</strong>.  It is not advisable to switch marker
-styles within a single document, for aesthetic reasons, but there
-is nothing to prevent you from doing so.)
-<p>
-If you want a range of line numbers (e.g.&nbsp;[5-11]&nbsp;),
-insert, directly into the first line of the range you want, the
-<a href="definitions.html#TERMS_INLINES">inline escape</a>,
-<strong>\*[EN-MARK]</strong>.  For the terminating line number of
-the range, you need only invoke <strong>.ENDNOTE</strong>, (again,
-without attaching <strong>\c</strong> to the text line before it).
-<strong>Mom</strong> is smart enough to figure out that where
-<strong>ENDNOTE</strong> was invoked represents the terminating
-line number.
-<a name="ENDNOTE_LINENUMBER_GAP"></a>
-<p>
-Given the impossibility of knowing, in advance, the "string length"
-of all the line numbers or ranges of line numbers that will be used
-in endnotes (the string length of 12 is two; the string length
-of 12-15 is 5), <strong>mom</strong> cannot "hang" line numbers
-and guarantee that they, and the endnote text, will align in a
-visually pleasing manner.  Consequently, <strong>mom</strong> sets
-the entirety of line-numbered endnotes completely flush left,
-<strong>including the line numbers themselves</strong>.  The line
-numbers (by default, enclosed in square brackets) are separated from
-the beginning of each endnote by a gap, so that a line-numbered
-endnote looks approximately like this:
-<p>
-<pre>
-	[1-2]   Notwithstanding, Frye later asserts that Christianity
-	is "a ghost  with the chains of a foul historical record of
-	cruelty clanking behind it."
-</pre>
-
-The default gap for <strong>PRINTSTYLE TYPESET</strong> and
-<strong>PRINSTYLE TYPEWRITE</strong> is 1.5
-<a href="definitions.html#TERMS_EM">ems</a>.
-You can change the size of the gap with the macro,
-<strong>ENDNOTE_LINENUMBER_GAP</strong>, which takes, as its single
-argument, the size of the gap.  The argument requires a
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>,
-so, for example, to change the gap to 2
-<a href="definitions.html#TERMS_PICASPOINTS">picas</a>,
-you'd do
-<p>
-<pre>
-	.ENDNOTE_LINENUMBER_GAP 2P
-</pre>
-
-<a name="ENDNOTE_LINENUMBER_BRACKETS"></a>
-By default, <strong>mom</strong> puts endnote line numbers inside
-square brackets.  The style of the brackets may be changed with
-the macro, <strong>ENDNOTE_LINENUMBER_BRACKETS</strong>, which
-takes one of three possible arguments: <strong>PARENS</strong>
-("round" brackets), <strong>SQUARE</strong> (the default) or
-<strong>BRACES</strong> (curly braces).  If you prefer a
-shortform, the arguments, <strong>(</strong>, <strong>[</strong> or
-<strong>{</strong> may be used instead.
-<a name="ENDNOTE_LINENUMBER_SEPARATOR"></a>
-<p>
-If you don't want the numbers enclosed in brackets, you may tell
-<strong>mom</strong> to use a "separator" instead.  A common
-separator would be the colon, but it can be anything you like.  The
-macro to do this is <strong>ENDNOTE_LINENUMBER_SEPARATOR</strong>,
-which takes, as its single argument, the separator you want.
-(If the argument contains spaces, don't forget to enclose the
-argument in double-quotes.)  The separator can be composed of
-any legal groff character, or any combination of characters.
-For example, to get a colon separator after the line number in
-line-numbered endnotes, you'd do

-Margin notes are short annotations that appear in either the left
-or right margin of a document.  Sometimes they comment on the text.
-Sometimes they assist in following the "flow" of a document by
-summarizing the subject of a portion of text.  Sometimes they're
-comments to yourself in a draft copy.
-<p>
-The margin notes macros and routines in om.tmac
-(<strong>mom</strong>) are "mommified" versions of the margin notes
-macros and routines written by Werner Lemberg and patched by Gaius
-Mulley.
-<p>
-
-<a name="MARGIN_NOTES_BEHAVIOUR"<h3><u>Margin notes behaviour</u></h3>
-<p>
-First things first: before you enter your first margin note, you
-must "initialize" margin notes with
-<a href="#MN_INIT">MN_INIT</a>.
-<strong>MN_INIT</strong> sets up the style parameters for margin
-notes, including things like
-<a href="definitions.html#TERMS_FONT">font</a>,
-<a href="definitions.html#TERMS_FAMILY">family</a>
-and
-<a href="definitions.html#TERMS_LEADING">leading</a>.
-<p>
-After initializing margin notes, you create margin notes with the
-<a href="#MN">MN</a>
-macro.  Based on the argument you pass <strong>MN</strong>, your
-margin note will go in either the left or the right margin.
-<p>
-Margin notes are tricky from a typographic standpoint with respect
-to vertical placement.  Since the leading of margin notes may
-differ from that of
-<a href="definitions.html#TERMS_RUNNING">running text</a>,
-it's impossible for <strong>mom</strong> to guess whether to align
-the first lines of margin notes with a document
-<a href="definitions.html#TERMS_BASELINE">baseline</a>,
-whether to align the last lines of margin notes with a document
-baseline, or whether to center them, vertically, so that neither
-first nor last line aligns with anything!
-<p>
-Given this difficulty, <strong>mom</strong> always aligns the first
-line of any margin note with a document baseline.  If you want a
-different behaviour, you must adjust the position(s) of margin
-notes yourself, on a note by note basis.  (See
-<a href="#MARGIN_NOTES_VERTICAL">Adjusting the vertical position of margin notes</a>.)
-<p>
-Generally speaking, <strong>mom</strong> tries to place margin
-notes at the point where you invoke the tag,
-<a href="#MN">MN</a>.
-However, in the event that a margin note runs deep, she may not
-be able to place a subsequent margin note exactly where you want.
-In such an instance, <strong>mom</strong> will "shift" the margin
-note down on the page, placing it one (margin note)
-linespace beneath the previous margin note (plus whatever vertical
-space is required to get the first line to line up with a baseline
-of running text).  A warning will be issued, letting you know this
-has happened, and where.
-<p>
-Sometimes, if a margin note has to be shifted down, there simply
-isn't enough room to start the margin note on the page on which
-<strong>MN</strong> is invoked.  In that case, <strong>mom</strong>
-ignores the margin note entirely and issues a warning, letting you
-know what she's done, and where.
-<p>
-In the event that a margin note, sucessfully begun on a page, 
-runs past your bottom margin (or the last line before footnotes
-begin), the margin note will "flow" onto the next page.  If it is a
-"left" margin note, it will continue in the left margin.  If it is a
-"right" margin note, it will continue in the right margin.
-<p>
-If your document is being set in two columns, <strong>mom</strong>
-will sensibly and automatically set all margin notes pertaining
-to the left column in the left margin, and all margin notes
-pertaining to the right column in the right margin, regardless of
-the "direction" argument you give the <strong>MN</strong> tag.  If
-you try to use <strong>MN</strong> in documents of more than two
-columns, <strong>mom</strong> will ignore all margin notes, and
-issue warning for each.
-<p>
-<h3><u><a name="MARGIN_NOTES_VERTICAL">Adjusting the vertical position of margin notes</a></u></h3>
-<p>
-When the
-<a href="definitions.html#TERM_LEADING">leading</a>
-of margin notes differs from the leading used throughout a document,
-you may want to adjust the vertical position of individual margin
-notes.  This is most often going to be the case with margin notes
-that end near the bottom of the page, where you want the last line of
-the margin note to line up with the last line of text on the page.
-<p>
-Adjustments to the vertical position of margin notes must be done
-inside the margin note (i.e. after <strong>MN</strong>), at the
-top, before entering text.  The commands to use are
-\!<a href="typesetting.html#ALD">.ALD</a>
-(to lower the margin note), and
-\!<a href="typesetting.html#RLD">.RLD</a>
-(to raise it).  The <strong>\!</strong> <em>must</em> precede the
-macros, or they won't have any effect.

-</a>
-<p>
-Before you enter your first margin note, you must initialize
-all the parameters associated with margin notes with
-<strong>MN_INIT</strong>.  If you forget to do so,
-<strong>mom</strong> will issue a warning and abort.
-<p>
-The argument list is quite long; an
-explanation of each argument follows.  Any argument whose value you
-want to be the default must be entered as "" (i.e. two
-double-quotes with no space between them).  Defaults for each
-argument are given in the explanation below.
-<p>
-<strong>[ ragged | symmetric ]</strong>
-<br>
-If the first argument is "ragged", both left and right margin notes
-will be flush left.  If the first argument is "symmetric", left
-margin notes will be set flush <em>right</em>, and right margin
-notes will be set flush <em>left</em>.  The effect is something
-like this:
-<p>
-<pre>
-	     A left    This is a meaningless batch        A right
-	margin note    of text whose sole purpose is      margin note
-	  with just    to demonstrate how the sym-        with just
-	a few words    metric argument to MN sets left    a few words
-	     in it.    and right margin notes.            in it.
-</pre>
-
-
-If the argument is omitted,
-or given as "", both left and right margin notes will be set
-justified.  (Justified is usually not a good idea, since the narrow
-measure of margin notes makes pleasing justification a near
-impossibility.)
-<p>
-<strong>left-width</strong>
-<br>
-The width of left margin notes.  A
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-must be appended directly onto the argument.  The default is to set
-left margin notes right out to the edge of the page, which is
-almost certainly not what you want, so you should give a value for
-this argument if using left margin notes.
-<p>
-<strong>right-width</strong>
-<br>
-The width of right margin notes.  A
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-must be appended directly onto the argument.  The default is to set
-right margin notes right out to the edge of the page, which is
-almost certainly not what you want, so you should give a value for
-this argument if using right margin notes.
-<p>
-<strong>gutter</strong>
-<br>
-The

-between margin notes and
-<a href="definitions.html#TERMS_RUNNING">running text</a>.
-A
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-must be appended directly onto the argument.  The gutter applies to
-both left and right margin notes. The default is 1
-<a href="definitions.html#TERMS_EM">em</a>.
-<p>
-<strong>font</strong>
-<br>
-The family+font for margin notes.  Yes, that's right: the family
-PLUS font combo.  For example, if you want Times Roman Medium,
-the argument must be TR.  If you want Palatino Medium Italic, the
-argument must be PI.  The default is the same family+font combo used
-for a document's paragraph text.
-<p>
-<strong>lead</strong>
-<br>
-The
-<a href="definitions.html#TERMS_LEADING">leading</a>
-of margin notes.  <strong>lead</strong> uses
-<a href="definitions.html#TERMS_PICASPOINTS">points</a>
-as its unit of measure, so don't tack a unit of measure onto the
-end of the argument.  The default lead is the same leading as
-is used for paragraph text (i.e. the document's base leading).
-For convenience and clarity, you may also give the word,
-<strong>DOC</strong>, to this argument, which indicates that the
-leading should be the same as the document's base leading.
-<p>
-<strong>colour</strong>
-<br>

-	<li><a href="#TOC_CONTROL">TOC control macros</a>
-</ul>
-
-<p>
-Want a table of contents for your document?  Easy.  Just enter
-<p>
-<pre>
-	.TOC
-</pre>
-
-as the very last macro of your document file. <strong>Mom</strong>
-will have picked up all document titles (in
-<a href="docprocessing.html#COLLATE">collated</a>
-documents), all heads, subheads, and paragraph heads, as well as any
-endnotes pages that have been output, and assigned them the
-appropriate page number (and page numbering style).  Talk about a
-no-brainer!
-
-That said, tables of contents (tocs) have even more control macros
-than endnotes.  As always, the reason for so many control macros is
-so that if you want to change just about any aspect of the toc's
-typographic appearance, you can.  <strong>Mom</strong> is all about
-simplicity AND flexibility.
-<p>
-
-<a name="TOC_BEHAVIOUR"><h3><u>TOC behaviour</u></h3></a>
-<p>
-When you output a toc (with
-<a href="#TOC">TOC</a>),
-<strong>mom</strong> finishes processing the last page of your document,
-then breaks to a new page for printing the toc.
-<p>
-<strong>Mom</strong> follows standard typesetting conventions for
-tables of contents.  To this end, if
-<a href="headfootpage.html#HEADERS">HEADERS</a>
-are on for the document, the first page of the toc has no page
-header, but does have a first page (roman numeral) number, always
-&quot;1&quot;, in the bottom margin.  If
-<a href="headfootpage.html#FOOTERS">FOOTERS</a>
-are on for the document, the first page has neither a footer, nor a
-page number in the top margin.  (If you absolutely must have a page
-footer on the first page of the toc, simply invoke
-<a href="headfootpage.html#FOOTER_ON_FIRST_PAGE">FOOTER_ON_FIRST_PAGE</a>
-immediately before <strong>TOC</strong>.)  Subsequent toc pages have
-both page headers or footers and a page number.
-<p>
-Entries in the toc are hierarchically indented, as you would
-expect.  By default, each type of entry (e.g. a head or a subhead)
-is set in a different font as well.  If any of heads, subheads or
-paragraph heads are numbered in the body of the document, they are
-also numbered in the toc.  Head numbering in the toc is NOT
-concatenated as it is in the body of the document, which would be
-visually redundant in a toc.
-<p>
-Tocs are never set in columns, regardless of whether the rest of
-the document is.  Lastly, if
-<a href="rectoverso.html#RECTO_VERSO">recto/verso</a>
-printing is enabled, the toc respects it.  This sometimes leads to
-tocs that begin with the wrong margins, but the margins can be
-corrected either by outputting a
-<a href="#BLANK_PAGE">BLANKPAGE</a>
-or by using the toc control macro
-<a href="#TOC_RV_SWITCH">TOC_RV_SWITCH</a>.
-<p>
-The overall toc
-<a href="definitions.html#TERMS_FAMILY">family</a>,
-<a href="definitions.html#TERMS_PS">point size</a>
-and
-<a href="definitions.html#TERMS_LEADING">lead</a>
-can be altered with the toc 
-<a href="definitions.html#TERMS_CONTROLMACRO">control macros</a>,
-as can the family,
-<a href="definitions.html#TERMS_FONT">font</a>,
-point size and indent of each type of toc entry (i.e. title, head,
-subhead, paragraph head).  Furthermore, the page numbering style
-can be changed, as can the amount of visual space reserved for toc
-entry page numbers.

-
-sets the base leading of type on the endnotes page to 1/2 inch.

-</a>
-<p>
-By default, <strong>mom</strong> allows room for 3 digits in the
-page number listings of tocs.  If you'd like some other number of
-placeholders, say 2, do
-<p>
-<pre>
-	.TOC_PADDING 2
-</pre>
-
-<!---FINIS--->
-
-<hr width="66%" align="left">
-<p>
-<a name="FINIS">
-	Macro: <strong>FINIS</strong>
-</a>
-
-<p>
-The use of <strong>FINIS</strong> is optional, but if you use
-it, it should be the last macro you invoke in a document (before
-<a href="#ENDNOTES">ENDNOTES</a>
-or
-<a href="#TOC">TOC</a>).
-See
-<a href="#FINIS_INTRO">above</a>
-for a description of how <strong>FINIS</strong> behaves.
-<p>
-<strong>NOTE:</strong> If you don't use <strong>FINIS</strong>,
-and you don't want
-<a href="definitions.html#TERMS_FOOTER">footers</a>
-(if they're on) or a page number at the bottom of the last page of
-a document, you have to turn them off manually, as the last two
-lines of your document file, like this:
-<p>
-<pre>
-	.FOOTERS OFF
-	.PAGINATE OFF
-</pre>
-
-<a name="FINIS_STRING"><h3><u>Changing the FINIS string</u></h3></a>
-
-<p>
-By default, <strong>FINIS</strong> prints the word
-END between
-<a href="definitions.html#TERMS_EM">em-dashes</a>.
-If you'd like <strong>mom</strong> to print something else
-between the dashes, use the <strong>FINIS_STRING</strong> macro
-(anywhere in the document prior to <strong>FINIS</strong>).
-<p>
-For example, if your document's in French, you'd do
-<p>
-<pre>
-	.FINIS_STRING "FIN"
-</pre>
-
-Double-quotes must enclose the macro's argument.
-<p>
-<strong>NOTE:</strong> If you pass <strong>FINIS_STRING</strong>
-a blank string, i.e.
-<p>
-<pre>
-	.FINIS_STRING ""
-</pre>
-
-<strong>mom</strong> will still print the em-dashes if you
-invoke <strong>FINIS</strong>.  This, in effect, produces a
-short, centred horizontal rule that terminates the document.
-(In
-<a href="docprocessing.html.#PRINTSTYLE">PRINTSTYLE TYPEWRITE</a>,
-it's a short, dashed line composed of four hyphens.)
-
-<a name="FINIS_COLOR"><h3><u>Changing the FINIS colour</u></h3></a>
-<p>
-Invoking <strong>FINIS_COLOR</strong> with a pre-defined (or
-&quot;initalized&quot;) color changes the colour of both the FINIS
-string and the em-dashes that surround it.  If you use the
-<a href="definitions.html#TERMS_INLINE">inline escape</a>,
-<a href="color.html#COLOR_INLINE">\*[&lt;colorname&gt;]</a>,
-in the argument passed to <strong>FINIS</strong>, only the text
-will be in the new colour; the em-dashes will be in the default
-document colour (usually black).

-<h2><a name="INTRO_MACROS_DOCPROCESSING"><u>Introduction to document processing</u></a></h2>
-
-As explained in
-<a href="intro.html#INTRO_DOCPROCESSING">Document processing with mom</a>,
-document processing uses markup tags to identify document elements
-such as heads, paragraphs, and so on.  The tags are, of course, macros,
-but with sensible, readable names that make them easy to grasp and
-easy to remember.  (And don't forget: if you don't like the
-&quot;official&quot; name of a tag -- too long, cumbersome
-to type in, not &quot;intuitive&quot; enough -- you can change it
-with the
-<a href="goodies.html#ALIAS">ALIAS</a>
-macro.)
-<p>
-In addition to the tags themselves, <strong>mom</strong> has an
-extensive array of macros that control how they look and behave.
-<p>
-Setting up a <strong>mom</strong> doc is a simple, four-part procedure.
-You begin by entering information about the document itself (title,
-subtitle, author, etc.).  Next, you tell <strong>mom</strong> what
-kind of document you're creating (e.g. chapter, letter, abstract,
-etc...) and what kind of output you want (typeset, typewritten,
-draft-style, etc).  Thirdly, you make as many or as few changes to
-<strong>mom</strong>'s default behaviour as you wish.  Lastly, you
-invoke the
-<a href="#START">START</a>
-macro.  Voilà!  You're ready to write.
-<p>
-<hr>
-
-
-<h2><a name="DEFAULTS"><u>Some document defaults</u></a></h2>
-
-As is to be expected, <strong>mom</strong> has defaults for everything.
-If you want to know a particular default, read about it in the
-description of the pertinent tag.
-<p>
-I fear the following may not be adequately covered in the
-documentation.  Just in case, here they are.
-<p>
-<ul>
-	<li>the paper size is 8.5x11 inches
-	<li>the left and right margins are 1-inch
-	<li>the top and bottom margins for document text are plus/minus
-		visually 1-inch
-	<li>pages are numbered; the number appears centred, at the
-		bottom, surrounded by hyphens ( e.g. -6- )
-	<li>the first page of a document begins with a
-		<a href="definitions.html#TERMS_DOCHEADER">document header</a>
-	<li>subsequent pages have
-		<a href="definitions.html#TERMS_HEADER">page headers</a>
-		with a rule underneath
-</ul>
-<p>
-Another way to check up on document processing defaults is to have
-a look at the macro file (om.tmac).  Each macro is preceded by a
-description that (generally) says what its default is (if it has
-one).
-<p>
-<hr>
-
-<a name="LEADING_NOTE">
-	<h2><u>IMPORTANT NOTE on leading/spacing and  bottom margins</u></h2>
-</a>
-
-<strong>Mom</strong> takes evenly-aligned  bottom margins in
-<a href="definitions.html#TERMS_RUNNING">running text</a>
-very seriously.  Only under a very few (exceptional) circumstances
-will she allow a bottom margin to &quot;hang&quot; (i.e. to fall
-short).
-<p>
-In order to ensure even bottom margins, <strong>mom</strong>
-uses the &quot;base&quot; document
-<a href="definitions.html#TERMS_LEADING">leading</a>
-in effect <em>at the start of running text on each page</em> (i.e.
-the leading used in paragraphs) to calculate the spacing of every
-document element.  Prior to invoking
-<a href="#START">START</a>,
-this is set with the
-<a href="typesetting.html#MACROS_TYPESETTING">typesetting macro</a>
-<a href="typesetting.html#LEADING">LS</a>,
-afterwards with the document
-<a href="definitions.html#TERMS_CONTROLMACRO">control macro</a>
-<a href="#DOC_LEAD">DOC_LEAD</a>.
-<p>
-Because <strong>mom</strong> relies so heavily on the base document
-leading, any change to the leading or spacing on a page will almost
-certainly have undesirable consequences on that page's bottom margin
-unless the change is fully compensated for elsewhere on the page.
-<p>
-In other words, if you add a few points of space somewhere on a page,
-you must subtract the same number of points somewhere else on that
-same page, and vice versa.
-<p>
-If it's a question of adding or subtracting full line spaces between
-or within document elements, you can do so by using the &quot;v&quot;
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-with whatever spacing macro you choose --
-<a href="typesetting.html#ALD">ALD</a>,
-<a href="typesetting.html#RLD">RLD</a>,
-<a href="typesetting.html#SPACE">SPACE</a>
--- and <strong>mom</strong> won't object.  &quot;v&quot; means
-&quot;the current leading&quot;, so she isn't confused by it.  And
-since &quot;v&quot; accepts decimal fractions, you can add/subtract
-half linespaces and quarter linespaces with &quot;v&quot; as well,
-<em>provided you compensate for the fractional linespace somewhere
-else on the page</em>.
-<p>
-If all this seems like too much work, <strong>mom</strong>
-provides a special macro to get you out of trouble if you've played
-around with leading and/or spacing.  The macro is called
-<strong>SHIM</strong> (like those little pieces of wood carpenters
-use to get their work even, level and snug), and it's described
-below.
-<p>
-
-<!---SHIM--->
-
-<hr width="66%" align="left">
-<p>
-<a name="SHIM"></a>
-Macro: <strong>SHIM</strong>
-
-<p>
-<strong>SHIM</strong> doesn't take any argument.  Use it whenever
-you've played around with the
-<a href="definitions.html#TERMS_LEADING">leading</a>
-or spacing on a page and you
-need to get <strong>mom</strong>'s document leading back on track.
-<p>
-For example, say you want to insert a picture into a document with
-the special groff macro, <strong>PSPIC</strong> (see the
-<strong>groff_tmac</strong> man page for usage).
-<p>
-Pictures aren't usually conveniently sized in multiples of document
-leading, which means that when you insert the picture, you disrupt
-<strong>mom</strong>'s ordered placement of baselines on the page.
-This will certainly result in a bottom margin that doesn't match the
-bottom margins of your document's other pages.
-<p>
-The solution is to insert <strong>SHIM</strong> after the picture,
-like this:
-<p>
-<pre>
-	&lt;some lines of text&gt;
-	.PSPIC &lt;full path to picture&gt;
-	.SHIM
-	&lt;more lines of text&gt;
-</pre>
-<strong>SHIM</strong> instructs <strong>mom</strong> to insert as
-much or a little space after the picture as is needed to ensure that
-the baseline of the next
-<a href="definitions.html#TERMS_OUTPUTLINE">output line</a>
-falls where <strong>mom</strong> would have put it had you not
-disrupted the normal flow of output lines with the picture.
-<p>
-And say, on previewing the above example, you find that the picture
-doesn't centre nicely between the lines of text, you can always do
-<p>
-<pre>
-	&lt;some lines of text&gt;
-	.RLD 3p
-	.PSPIC &lt;full path to picture&gt;
-	.SHIM
-	&lt;more lines of text&gt;
-</pre>
-
-to raise the picture slightly
-(<strong>R</strong>everse <strong>L</strong>ea<strong>D</strong>
-3 points; see
-<a href="typesetting.html#RLD">RLD</a>),
-and still have <strong>SHIM</strong> ensure that text underneath
-falls exactly where it's supposed to.

-	<h3><u>Tutorial -- Setting up a mom document</u></h3>
-</a>
-There are four &quot;parts&quot; to setting up a <strong>mom</strong>
-doc (three, actually, with one optional).  Before we proceed, though,
-be reassured that something as simple as
-<p>
-<pre>
-	.TITLE     "By the Shores of Lake Attica"
-	.AUTHOR    "Rosemary Winspeare"
-	.PRINTSTYLE TYPESET
-	.START
-</pre>
-
-produces a beautifully typeset 8.5x11 document, with a
-<a href="definitions.html#TERMS_DOCHEADER">docheader</a>
-at the top of page 1,
-<a href="definitions.html#TERMS_HEADER">page headers</a>
-with the title and author on subsequent
-pages, and page numbers at the bottom of each page.  In the course
-of the document, heads, subheads, citations, quotes, epigraphs,
-and so on, all come out looking neat, trim, and professional.
-<p>
-For the purposes of this tutorial, we're going to set up a short
-story -- <em>My Pulitzer Winner</em> by Joe Blow.  Thankfully,
-we don't have to look at story itself, just the setup.
-Joe wants the document
-<p>
-<ul>
-	<li>to be draft 7, revision 39;
-	<li>to use the &quot;default&quot; style of document formatting:
-	<li>to print as draft-style output (instead of &quot;final&quot; copy output);
-	<li>to be typeset, in Helvetica, 12 on 14,
-		<a href="definitions.html#TERMS_RAG">rag-right</a>;
-	<li>to have <a href="definitions.html#TERMS_FOOTER">footers</a>
-		instead of
-		<a href="definitions.html#TERMS_HEADER">headers</a>;
-	<li>to use a single asterisk for
-		<a href="definitions.html#TERMS_LINEBREAK">author linebreaks</a>.
-</ul>
-<p>
-Joe Blow has no taste in typography.  His draft won't look pretty,
-but this is, after all, a tutorial; we're after examples, not beauty.
-<h3><u>Step 1</u></h3>
-
-The first step in setting up any document is giving <strong>mom</strong>
-some reference information.  The reference macros are:
-<p>
-<ul>
-	<li>TITLE
-	<li>DOCTITLE
-	<li>COVERTITLE
-	<li>SUBTITLE
-	<li>AUTHOR
-	<li>CHAPTER -- the chapter number
-	<li>DRAFT -- the draft number
-	<li>REVISION -- the revision number
-	<li>COPYRIGHT -- only used on cover pages
-	<li>MISC -- only used on cover pages
-	<li>COVER_TITLE -- only on cover pages; only if needed
-	<li>DOC_COVER_TITLE -- only on document cover pages; only if needed
-</ul>
-<p>
-You can use as many or as few as you wish, although at a minimum,
-you'll probably fill in <strong>TITLE</strong> (unless the document's
-a letter) and <strong>AUTHOR</strong>.  Order doesn't matter.
-You can separate the
-<a href="definitions.html#TERMS_ARGUMENTS">arguments</a>
-from the macros by any number of spaces.  The following are
-what you'd need to start Joe Blow's story.
-<p>
-<pre>
-	.TITLE    "My Pulitzer Winner"
-	.AUTHOR   "Joe Blow"
-	.DRAFT     7
-	.REVISION  39
-</pre>
-
-<h3><u>Step 2</u></h3>
-
-Once you've given <strong>mom</strong> the reference information she
-needs, you tell her how you want your document formatted.  What kind
-of document is it?  Should it be typeset or typewritten?  Is this
-a &quot;final&quot; copy (for the world to see) or just a draft?
-<strong>Mom</strong> calls the macros that answer these questions
-&quot;the docstyle macros.&quot;  They are:
-<p>
-<ul>
-	<li>DOCTYPE -- the type of document (default, chapter, user-defined, letter)
-	<li>PRINTSTYLE -- typeset or typewritten
-	<li>COPYSTYLE  -- draft or final copy
-</ul>
-<p>
-<strong>Mom</strong> has defaults for <strong>DOCTYPE</strong>
-and <strong>COPYSTYLE</strong>; if they're what you want, you
-don't need to include them here.  However, <strong>PRINTSTYLE</strong>
-has no default and MUST be present in every formatted document.
-If you omit it, <strong>mom</strong> won't process the document AND
-she'll complain (both to stderr and as a single printed sheet with
-a warning).  Moms -- they can be so annoying sometimes. &lt;sigh&gt;
-<p>
-Adding to what we already have, the next bit of setup for Joe
-Blow's story looks like this:
-<p>
-<pre>
-	.TITLE    "My Pulitzer Winner"
-	.AUTHOR   "Joe Blow"
-	.DRAFT     7
-	.REVISION  39
-	\#
-	.DOCTYPE     DEFAULT \"Superfluous; mom uses DOCTYPE DEFAULT by default
-	.PRINTSTYLE  TYPESET
-	.COPYSTYLE   DRAFT
-</pre>
-
-Notice the use of the
-<a href="definitions.html#TERMS_COMMENTLINES">comment line</a>
-( \# ), a handy way to keep groups of macros visually separated
-for easy reading in a text editor.
-
-<h3><u>Step 3</u></h3>
-
-This step -- completely optional -- is where you, the user, take
-charge.  <strong>Mom</strong> has defaults for <em>everything</em>,
-but who's ever satisfied with defaults?  Use any of the <a
-href="typesetting.html#MACROS_TYPESETTING">typesetting macros</a>
-here to change <strong>mom</strong>'s document defaults (paper
-size, margins, family, point size, line space, rag, etc), or
-any of the document processing macros that set/change/control
-the appearance of document elements.  Think of this as the
-&quot;style-sheet &quot; section of a document.  And please note:
-you MUST give <strong>mom</strong> a
-<a href="#PRINTSTYLE">PRINTSTYLE</a>
-directive <strong>before</strong> making any such changes.
-<p>
-Joe Blow wants his story printed in Helvetica, 12 on 14, rag
-right, with
-<a href="definitions.html#TERMS_FOOTER">page footers</a>
-instead of
-<a href="definitions.html#TERMS_HEADER">page headers</a>
-and a single asterisk for the
-<a href="definitions.html#TERMS_LINEBREAK">linebreak</a>
-character.  None of these requirements conforms
-to <strong>mom</strong>'s defaults for the chosen
-<strong>PRINTSTYLE</strong> (TYPESET), so we change them here.
-The setup for Joe Blow's story now looks like this:
-<p>
-<pre>
-	.TITLE    "My Pulitzer Winner"
-	.AUTHOR   "Joe Blow"
-	.DRAFT     7
-	.REVISION  39
-	\#
-	.DOCTYPE     DEFAULT
-	.PRINTSTYLE  TYPESET
-	.COPYSTYLE   DRAFT
-	\#
-	.FAMILY  H
-	.PT_SIZE 12
-	.LS      14
-	.QUAD    LEFT    \"i.e. rag right
-	.FOOTERS
-	.LINEBREAK_CHAR *
-</pre>
-
-<h3><u>Step 4</u></h3>
-The final step in setting up a document is telling <strong>mom</strong>
-to start document processing.  It's a no-brainer, just the single macro
-<strong>START</strong>.  Other than <strong>PRINTSTYLE</strong>, it's
-the only macro required for document processing (although
-I can't guarantee you'll like the results of using just the two).
-<p>
-Here's the complete setup for <em>My Pulitzer Winner</em>:
-<p>
-<pre>
-	.TITLE    "My Pulitzer Winner"
-	.AUTHOR   "Joe Blow"
-	.DRAFT     7
-	.REVISION  39
-	\#
-	.DOCTYPE     DEFAULT
-	.PRINTSTYLE  TYPESET
-	.COPYSTYLE   DRAFT
-	\#
-	.FAMILY   H
-	.PT_SIZE  12
-	.LS       14
-	.QUAD     LEFT    \"i.e. rag right
-	.FOOTERS
-	.LINEBREAK_CHAR *
-	\#
-	.START
-</pre>
-
-As pointed out earlier, Joe Blow is no typographer.  Given that all he
-needs is a printed draft of his work, a simpler setup would have been:
-<p>
-<pre>
-	.TITLE    "My Pulitzer Winner"
-	.AUTHOR   "Joe Blow"
-	.DRAFT     7
-	.REVISION  39
-	\#
-	.PRINTSTYLE  TYPEWRITE
-	.COPYSTYLE   DRAFT
-	\#
-	.START
-</pre>
-
-<kbd>.PRINTSTYLE TYPEWRITE</kbd>, above, means that Joe's work
-will come out &quot;typewritten, double-spaced&quot;, making the
-blue-pencilling he (or someone else) is sure to do much
-easier (which is why many publishers and agents still insist on
-typewritten, double-spaced copy).
-<p>
-When J. Blow stops re-writing and decides to print off a final,
-typeset copy of his work for the world to see, he need only
-make two changes to the (simplified) setup:
-<p>
-<pre>
-	.TITLE    "My Pulitzer Winner"
-	.AUTHOR   "Joe Blow"
-	.DRAFT     7
-	.REVISION  39
-	\#
-	.PRINTSTYLE  TYPESET  \"first change
-	.COPYSTYLE   FINAL    \"second change
-	\#
-	.START
-</pre>
-
-In the above, <kbd>.DRAFT 7, .REVISION 39,</kbd> and <kbd>.COPYSTYLE
-FINAL</kbd> are actually superfluous.  The draft and revision numbers
-aren't used when <strong>COPYSTYLE</strong> is <strong>FINAL</strong>,
-and <strong>COPYSTYLE FINAL</strong> is <strong>mom</strong>'s
-default unless you tell her otherwise.  BUT... to judge from the
-number of drafts already, J. Blow may very well decide his
-&quot;final&quot; version still isn't up to snuff.  Hence, he might
-as well leave in the superfluous macros.  That way, when draft 7,
-rev. 62 becomes draft 8, rev. 1, he'll be ready to tackle his Pulitzer
-winner again.

-If you omit <strong>CHAPTER</strong> when setting up your reference

-If the <strong>COPYSTYLE</strong> is <strong>FINAL</strong> (the

-(i.e. the draft number) beside the word &quot;Draft&quot; in the

-<p>
-<strong>A small word of caution:</strong> If your argument to
-<strong>.DRAFT</strong> is more than one word long, you must
-enclose the argument in double-quotes.
-<p>
-You may, if you wish, invoke <strong>.DRAFT</strong> without an

-like this:
-<p>
-<pre>
-	.DRAFT_STRING "Jet"
-</pre>
-
-Equally, <strong>DRAFT_STRING</strong> can be used to roll your own
-solution to something other than the word &quot;Draft.&quot;  For
-example, you might want &quot;Trial run alpha-three&quot; to appear
-in the headers of a draft version.  You'd accomplish this by doing
-<p>
-<pre>
-	.DRAFT alpha-three
-	.DRAFT_STRING "Trial run
-</pre>
-
-<strong>.DRAFT</strong> without an argument, above, ensures that
-only the <strong>DRAFT_STRING</strong> gets printed.
-<p>
-<strong>NOTE:</strong> If you define both a blank <strong>.DRAFT</strong>
-and a blank <strong>.DRAFT_STRING</strong>, <strong>mom</strong>
-skips the draft field in headers entirely.  If this is what you
-want, this is also the only way to do it.  Simply leaving out
-<strong>.DRAFT</strong> and <strong>.DRAFT_STRING</strong> will

-<strong>REVISION_STRING</strong> macro, like this:
-<p>
-<pre>
-	.REVISION_STRING "Rév."
-</pre>
-
-Additionally, you may sometimes want to make use of
-<strong>mom</strong>'s
-<a href="#COPYSTYLE">COPYSTYLE DRAFT</a>
-but not actually require any draft information.  For example, you
-might like <strong>mom</strong> to indicate only the revision number
-of your document.  The way to do that is to define an empty
-<strong>.DRAFT</strong> and <strong>.DRAFT_STRING</strong> in
-addition to <strong>.REVISION</strong>, like this:
-<p>
-<pre>
-	.DRAFT
-	.DRAFT_STRING
-	.REVISION 2
-</pre>
-
-<p>
-Equally, if you want to roll your own solution to what revision
-information appears in headers, you could do something like this:
-<pre>
-	.DRAFT
-	.DRAFT_STRING
-	.REVISION "two-twenty-two"
-	.REVISION_STRING "Revision"
-</pre>
-
-<p>
-The above, naturally, has no draft information.  If you want to
-roll your own <strong>.DRAFT</strong> and/or
-<strong>.DRAFT_STRING</strong> as well, simply supply arguments to
-either or both.

-<p>
-<strong>CHAPTER</strong> prints &quot;Chapter #&quot; in place of a
-<a href="definitions.html#TERMS_DOCHEADER">docheader</a>
-(# is what you gave to the
-<a href="#REFERENCE_MACROS">reference macro</a>
-<a href="#CHAPTER">CHAPTER</a>).
-If you give the chapter a title with
-<a href="#CHAPTER_TITLE">CHAPTER TITLE</a>,
-<strong>mom</strong> prints &quot;Chapter #&quot; and the title
-underneath.  If you omit the
-<a href="#CHAPTER">CHAPTER</a>
-reference macro but supply a
-<a href="#CHAPTER_TITLE">CHAPTER_TITLE</a>,
-<strong>mom</strong> prints only the chapter title. <em>(*For
-backward compatibility with pre-1.1.5 versions of</em>
-<strong>mom</strong><em>, you can also supply a chapter title by
-omitting the</em> <strong>CHAPTER</strong> <em>reference macro and
-supplying a chapter title with</em>
-<a href="#CHAPTER_STRING">CHAPTER_STRING</a>.)
-<p>
-The page headers in <strong>DOCTYPE CHAPTER</strong> contain the author,
-the title of the book (which you gave with
-<a href="#TITLE">TITLE</a>),
-and &quot;Chapter #&quot; (or the chapter title).  See
-<a href="headfootpage.html#HEADER_STYLE">Default Specs for Headers</a>
-for <strong>mom</strong>'s default type parameters for each part of
-the page header.
-<p>
-<strong>NAMED</strong> takes an additional argument: a name
-for this particular kind of document  (e.g. outline, synopsis,
-abstract, memorandum), enclosed in double-quotes.
-<strong>NAMED</strong> is identical to <strong>DEFAULT</strong>
-except that <strong>mom</strong> prints the argument to
-<strong>NAMED</strong> beneath the
-<a href="definitions.html#TERMS_DOCHEADER">docheader</a>,
-as well as in page headers.
-(See
-<a href="headfootpage.html#HEADER_STYLE">Default specs for headers</a>
-for how <strong>mom</strong> outputs each part of the page header.)
-<p>
-Additionally, if you wish the name of this particular kind of
-document to be coloured, you can pass <strong>DOCTYPE NAMED</strong>
-a third (optional) argument: the name of a colour pre-defined (or
-&quot;initialized&quot;) with
-<a href="color.html#NEWCOLOR">NEWCOLOR</a>
-or
-<a href="color.html#XCOLOR">XCOLOR</a>.
-For example, if you have a doctype named &quot;Warning&quot;, and
-you'd like &quot;Warning&quot; to be in red, assuming you've
-pre-defined (or &quot;initialized&quot;) the color, red, this is
-what the <strong>DOCTYPE</strong> entry would look like:
-<p>
-<pre>
-	.DOCTYPE NAME "Warning" red
-</pre>
-
-<p>
-<strong>LETTER</strong> tells mom you're writing a letter.  See

-<nobr>Macro: <strong>PRINTSTYLE</strong> TYPESET | TYPEWRITE [ SINGLESPACE ]</nobr>
-<br>
-<em>*Required for document processing.</em>
-<br>
-<em>*Must come before any changes to default document style</em>
-
-<p>
-<strong>PRINTSTYLE</strong> tells <strong>mom</strong> whether to typeset
-a document, or to print it out &quot;typewritten, doubled-spaced&quot;.
-<p>
-<strong>THIS MACRO MAY NOT BE OMITTED.</strong>  In order for
-document processing to take place, <strong>mom</strong> requires
-a <strong>PRINTSTYLE</strong>.  If you don't give one,
-<strong>mom</strong> will warn you on stderr and print a single
-page with a nasty message.
-<p>
-Furthermore, <strong>PRINTSTYLE</strong> must come before any
-changes to <strong>mom</strong>'s default typestyle parameters.
-(This applies primarily to, but is by no means restricted to,
-<strong>PRINTSTYLE TYPESET</strong>.)  <strong>PRINTSTYLE</strong>
-sets up complete &quot;templates&quot; that include default
-papersize, margins, family, fonts, point sizes, and so on.
-Therefore, changes to any aspect of document style must come
-afterwards.
-<p>
-<strong>TYPESET</strong>, as the argument implies, typesets documents
-(by default in Times Roman; see
-<a href="#TYPESET_DEFAULTS">TYPESET defaults</a>).
-You have full access to all the
-<a href="typesetting.html#MACROS_TYPESETTING">typesetting macros</a>
-as well as the
-<a href="definitions.html#STYLE_CONTROL">style control macros</a>
-of document processing.
-<p>
-As mentioned above, <strong>PRINTSTYLE TYPESET</strong> must come
-before any changes to <strong>mom</strong>'s default typographic
-settings.  For example,
-
-<pre>
-	.PAPER A4
-	.LS 14
-	.PRINTSTYLE TYPESET
-</pre>
-
-will not changes <strong>mom</strong>'s default paper size to A4,
-nor her default document leading 14 points, whereas
-
-<pre>
-	.PRINTSTYLE TYPESET
-	.PAPER A4
-	.LS 14
-</pre>
-
-will.
-<p>
-With <strong>TYPEWRITE</strong>, <strong>mom</strong> does her best
-to reproduce the look and feel of typewritten, double-spaced copy (see
-<a href="#TYPEWRITE_DEFAULTS">TYPEWRITE defaults</a>).
-<a href="docelement.html#DOCELEMENT_CONTROL">Control macros</a>
-and
-<a href="typesetting.html#INTRO_MACROS_TYPESETTING">typesetting macros</a>
-that alter family, font, point size, and
-<a href="definitions.html#TERMS_LEADING">leading</a>
-are (mostly) ignored.  An important exception is
-<a href="headfootpage.html#HDRFTR_GLOBAL_SIZE">HEADER_SIZE</a>
-(and, by extension, <strong>FOOTER_SIZE</strong>), which allows
-you to reduce the point size of headers/footers should they become
-too crowded.  Most of <strong>mom</strong>'s inlines affecting the
-appearance of type are also ignored (<strong>\*S</strong> is an
-exception; there may be a few others).
-<p>
-In short, <strong>TYPEWRITE</strong> never produces effects other than
-those available on a typewriter.  Don't be fooled by how brainless
-this sounds; <strong>mom</strong> is remarkably sophisticated when
-it comes to conveying the typographic sense of a document within the
-confines of <strong>TYPEWRITE</strong>.
-<p>
-The primary uses of <strong>TYPEWRITE</strong> are: outputting hard
-copy drafts of your work (for editing), and producing documents
-for submission to publishers and agents who (wisely) insist on
-typewritten, double-spaced copy. To get a nicely typeset version of
-work that's in the submission phase of its life (say, to show fellow
-writers for critiquing), simply change <strong>TYPEWRITE</strong>
-to <strong>TYPESET</strong> and print out a copy.
-<p>
-If, for some reason, you would prefer the output of
-<strong>TYPEWRITE</strong> single-spaced, pass <strong>PRINTSTYLE
-TYPEWRITE</strong> the optional argument, <strong>SINGLESPACE</strong>.
-<p>
-If you absolutely must have a leading other than typewriter double-
-or singlespaced, the only way to get it is with the
-<a href="#DOC_LEAD">DOC_LEAD</a>
-macro, and then ONLY if <strong>DOC_LEAD</strong> is set
-<strong>before</strong> you invoke the <strong>START</strong>
-macro.

-includes the
-<a href="typesetting.html#SLANT_INLINE">\*[SLANT]</a>
-<a href="definitions.html#TERMS_INLINES">inline escape</a>
-for pseudo-italics.
-<p>
-If you'd prefer that <strong>mom</strong> were

-you'd like italics and pseudo-italics to come out as italics),
-use the control macros <strong>.ITALIC_MEANS_ITALIC</strong> and
-<strong>.SLANT_MEANS_SLANT</strong>.  Neither requires an
-argument.
-<p>
-Although it's unlikely, should you wish to reverse the sense of
-these macros in the midst of a document,
-<strong>.UNDERLINE_ITALIC</strong> and
-<strong>.UNDERLINE_SLANT</strong> restore underlining of
-italics and pseudo-italics.
-<p>
-<a name="UNDERLINE_QUOTES"></a>
-Additionally, by default, <strong>mom</strong> underlines
-<a href="definitions.html#TERMS_QUOTES">quotes</a>
-(but not
-<a href="definitions.html#TERMS_BLOCKQUOTES">blockquotes</a>)
-in <strong>PRINTSTYLE TYPEWRITE</strong>.
-If you don't like this behaviour, turn it off with

-While most of the

-is an important exception:
-<a href="headfootpage.html#HDRFTR_GLOBAL_SIZE">HEADER_SIZE</a>
-(and by extension, <strong>FOOTER_SIZE</strong>).  This is
-particularly useful for reducing the point size of

-<p>
-<a name="COPYSTYLE"></a>
-<nobr>Macro: <strong>COPYSTYLE</strong> DRAFT | FINAL</nobr>
-
-<p>
-<strong>Mom</strong>'s default <strong>COPYSTYLE</strong> is
-<strong>FINAL</strong>, so you don't have to use this macro unless
-you want to.
-<p>
-<strong>COPYSTYLE DRAFT</strong> exhibits the following behaviour:
-<br>
-<ol>
-	<li>documents start on page 1, whether or not you
-		request a different starting page number with
-		<a href="headfootpage.html#PAGENUMBER">PAGENUMBER</a>
-	<li>page numbers are set in lower case roman numerals
-	<li>the draft number supplied by 
-		<a href="#DRAFT">DRAFT</a>
-		and a revision number, if supplied with 
-		<a href="#REVISION">REVISION</a>
-		(see
-		<a href="#REFERENCE_MACROS">reference macros</a>),
-		appear in the centre part of
-		<a href="definitions.html#TERMS_HEADER">page headers</a>
-		(or footers, depending on which you've selected) along with
-		any other information that normally appears there.
-</ol>
-<p>
-<strong>IMPORTANT:</strong> If you define your own centre part for page
-headers with
-<a href="headfootpage.html#HDRFTR_CENTER">HEADER_CENTER</a>,
-no draft and/or revision number will appear there.  If you want draft
-and revision information in this circumstance, use
-<a href="headfootpage.html#DRAFT_WITH_PAGENUMBER">DRAFT_WITH_PAGENUMBER</a>.
-<p>
-<strong>COPYSTYLE FINAL</strong> differs from <strong>DRAFT</strong> in that:
-<br>
-<ol>
-	<li>it respects the starting page number you give the document
-	<li>page numbers are set in normal (Arabic) digits
-	<li>no draft or revision number appears in the page headers
-</ol>
-<p>
-<strong>NOTE:</strong> The centre part of page headers can get crowded,
-especially with
-<a href="docprocessing.html#DOCTYPE">DOCTYPE CHAPTER</a>
-and
-<a href="docprocessing.html#DOCTYPE">DOCTYPE NAMED</a>,
-when the <strong>COPYSTYLE</strong> is <strong>DRAFT</strong>.
-Three mechanisms are available to overcome this problem.  One is to
-reduce the overall size of headers (with
-<a href="headfootpage.html#HDRFTR_GLOBAL_SIZE">HEADER_SIZE</a>).
-Another, which only works with
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE TYPESET</a>,
-is to reduce the size of the header's centre part only (with
-<a href="headfootpage.html#_SIZE">HEADER_CENTER_SIZE</a>).
-And finally, you can elect to have the draft/revision information
-attached to page numbers instead of having it appear in the centre
-of page headers (see
-<a href="headfootpage.html#DRAFT_WITH_PAGENUMBER">DRAFT_WITH_PAGENUMBER</a>).

-<a name="TYPE_BEFORE_START"><h2><u>Using the typesetting macros prior to START</u></h2></a>
-<p>
-From time to time (or maybe frequently), you'll want the overall
-look of a document to differ from <strong>mom</strong>'s defaults.
-Perhaps you'd like her to use a different
-<a href="definitions.html#TERMS_FAMILY">family</a>,
-or a different overall
-<a href="definitions.html#TERMS_LEADING">leading</a>,
-or have different left and/or right page margins.
-<p>
-To accomplish such alterations, use the appropriate
-<a href="typesetting.html#MACROS_TYPESETTING">typesetting macros</a>
-(listed below) <strong>after</strong>
-<a href="#PRINTSTYLE">PRINTSTYLE</a>
-and <strong>before</strong>
-<a href="#START">START</a>.
-<p>
-More than one user has, quite understandably, not fully grasped
-the significance of the preceding sentence.  The part they've missed
-is &quot;<u>after <strong>PRINTSTYLE</strong></u>&quot;.
-<p>
-Changes to any aspect of the default look and/or formatting
-of a <strong>mom</strong> document must come after
-<strong>PRINTSTYLE</strong>.  For example, it might seem natural to
-set up page margins at the very top of a document with
-<p>
-<pre>
-	.L_MARGIN 1i
-	.R_MARGIN 1.5i
-</pre>
-
-However, when you invoke <strong>.PRINTSTYLE</strong>, those
-margins will be overridden.  The correct place to set margins--and
-all other changes to the look of a document--is <strong>after
-PRINTSTYLE</strong>.
-
-<p>
-<strong>NOTE:</strong> Don't use the macros listed in <a
-href="#DOC_PARAM_MACROS">Changing document-wide typesetting
-parameters after START</a> prior to <strong>START</strong>; they are
-exclusively for use afterwards.
-<p>
-When used before
-<strong>START</strong>,
-the
-<a href="typesetting.html#MACROS_TYPESETTING">typesetting macros</a>
-(below) have the following meanings:
-<p>
-<pre>
-	L_MARGIN       Left margin of pages, including headers/footers
-	R_MARGIN       Right margin of pages, including headers/footers
-	T_MARGIN       The point at which running text (i.e. not
-	               headers/footers or page numbers) starts on each page
-	B_MARGIN*      The point at which running text (i.e. not
-	(see note)     headers/footers or page numbers) ends on each page
-
-	PAGE           If you use PAGE, its final four arguments have the
-	               same meaning as L_ R_ T_ and B_MARGIN (above).
-
-	LL             The line length for everything on the page;
-	               equivalent to setting the right margin with R_MARGIN
-	FAMILY         The family of all type in the document
-	PT_SIZE        The point size of type in paragraphs; mom uses this
-	               to calculate automatic point size changes (e.g. for
-	               heads, footnotes, quotes, headers, etc)
-	LS/AUTOLEAD**  The leading used in paragraphs; all leading and spacing
-	               of running text is calculated from this
-
-	QUAD/JUSTIFY   Affects paragraphs only
-	LEFT           No effect***

-<strong>DOC_LEAD_ADJUST</strong> is a special macro to adjust

-<a href="definitions.html#TERMS_LEADING">leading</a>
-so that bottom margins fall precisely where you expect.
-<p>
-If you invoke <strong>DOC_LEAD_ADJUST</strong>, <strong>mom</strong>

-to the leading until the maximum number of lines at the new leading
-matches the bottom margin.  In most instances, the difference
-between the requested lead and the adjusted lead is
-unnoticeable, and since in almost all cases adjusted leading is
-what you want, it's <strong>mom</strong>'s default.
-<p>
-Should you NOT want adjusted document leading, you MUST turn it

-determine where <strong>mom</strong> ends

-In

-
-This starts the document 1.5 inches from the top of the page PLUS
-whatever spacing adjustment <strong>mom</strong> has to make in
-order to ensure that the first baseline of running text falls on a

-of the first line of type.
-<p>
-<strong>TIP:</strong> Since no document processing happens until
-you invoke
-<a href="#START">START</a>
--- including anything to do with docheaders -- you can typeset
-your own docheader prior to <strong>START</strong> (if you don't
-like the way <strong>mom</strong> does things) and use
-<strong>DOCHEADER OFF</strong> with its optional distance argument
-to ensure that the body of your document starts where you want.
-You can even insert a PostScript file (with <strong>.PSPIC</strong>;

-
-<p>
-With
-<a href="#PRINTSTYLE">PRINTSTYLE TYPEWRITE</a>,
-the look of docheaders is carved in stone.
-In
-<a href="#PRINTSTYLE">PRINTSTYLE TYPESET</a>,
-however, you can make a lot of changes.  Macros that alter docheaders
-MUST come before
-<a href="#START">START</a>.
-<a name="DOCHEADER_DESC"></a>
-<p>
-A typeset docheader has the following characteristics.  Note that
-title, subtitle, author, and document type are what you supply
-with the
-<a href="#REFERENCE_MACROS">reference macros</a>.
-Any you leave out will not appear; <strong>mom</strong> will
-compensate:
-<p>
-<pre>
-	    TITLE         bold, 3.5 points larger than running text (not necessarily caps)
-	   Subtitle       medium, same size as running text
-	      by          medium italic, same size as running text
-	   Author(s)      medium italic, same size as running text
-
-	(Document type)   bold italic, underscored, 3 points larger than running text
-</pre>
-
-If the
-<a href="#DOCTYPE">DOCTYPE</a>
-is CHAPTER,
-<pre>
-	   Chapter #       bold, 4 points larger than running text
-	 Chapter Title     bold italic, 4 points larger than running text
-</pre>
-
-<p>
-The
-<a href="definitions.html#TERMS_FAMILY">family</a>
-is the prevailing family of the whole document.
-<p>
-<strong>NOTE:</strong> If your <strong>DOCTYPE</strong> is
-<strong>CHAPTER</strong> and you have both &quot;Chapter #&quot;
-and a &quot;Chapter Title&quot; (as above), you may find the
-<a href="definitions.html#TERMS_LEADING">leading</a>
-a bit cramped (owing to <strong>mom</strong>'s default docheader
-leading).  If this is the case, you can adjust the leading either
-with
-<a href="#ADJUST_LEADING">DOCHEADER_LEAD</a>
-or by including the

-<p>
-By default, a docheader starts on the same
-<a href="definitions.html#TERMS_BASELINE">baseline</a>
-as
-<a href="definitions.html#TERMS_RUNNING">running text</a>.
-If you'd like it to start somewhere else, use the macro

-(measured from the top edge of the paper to the first baseline
-of the docheader), like this:
-<p>
-<pre>
-	.DOCHEADER_ADVANCE 4P
-</pre>
-
-A
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-is required.
-<p>
-<strong>NOTE:</strong> If
-<a href="headfootpage.html#HEADERS">HEADERS</a>

-margin for
-<a href="definitions.html#TERMS_RUNNING">running text</a>
-(7.5
-<a href="definitions.html#TERMS_PICASPOINTS">picas</a>)
-changes to 6 picas (visually approx. 1 inch).  Since the
-first baseline of the docheader falls on the same baseline
-as the first line of running text (on pages after page 1),
-you might find the docheaders a bit high when headers are off.
-Use
-<a href="#CHANGE_START">DOCHEADER_ADVANCE</a>
-to place them where you want.
-<p>
-
-<a name="DOCHEADER_FAMILY"><h3><u>2. Change the family of the entire docheader</u></h3></a>
-<p>
-By default, <strong>mom</strong> sets the docheader in the same
-family used for 
-<a href="definitions.html#TERMS_RUNNING">running text</a>.
-If you'd prefer to have your docheaders set in a different family,
-invoke <strong>DOCHEADER_FAMILY</strong> with the family you want.
-The argument for <strong>DOCHEADER_FAMILY</strong> is the same as
-for
-<a href="typesetting.html#FAMILY">FAMILY</a>.
-<p>
-For example, <strong>mom</strong>'s default family for running text
-is Times Roman.  If you'd like to keep that default, but have the
-docheaders set entirely in Helvetica,
-<p>
-<pre>
-	.DOCHEADER_FAMILY H
-</pre>
-
-is how you'd do it.
-<p>
-Please note that if you use <strong>DOCHEADER_FAMILY</strong>,
-you can still alter the family of individual parts of the docheader
-with the macros listed
-<a href="#CHANGE_FAMILY">here</a>.
-
-<a name="ADJUST_LEADING"><h3><u>3. Adjust the leading</u></h3></a>
-<p>
-The

-of docheaders is the same as running text (except when
-<a href="#DOCTYPE">DOCTYPE</a>
-is <strong>CHAPTER</strong> <em>and</em> both a chapter number and a
-chapter title have been supplied, in which case the default is 4 points
-more than running text.)
-<p>
-If you'd like your docheaders to have a different leading, say, 2
-points more than the lead of running text, use:
-<p>
-<pre>
-	.DOCHEADER_LEAD +2
-</pre>
-
-Since the leading of docheaders is calculated from the lead of running
-text, a + or - sign is required before the argument (how much to add
-or subtract from the lead of running text).  No 
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-is required; points is assumed.

-            reference macro AND a <strong>CHAPTER_TITLE</strong>
-            macro.  Otherwise, the macro,

-An embedded colour will cause the string to be colourized any time

-<a name="CHANGE_SIZE"><h3><u>7. Adjust the size of docheader elements</u></h3></a>
-<p>
-The following macros let you adjust the point size of each docheader
-element separately.
-<p>
-<strong>Mom</strong> calculates the point size
-of docheader elements from the point size of paragraphs in running
-text, so you must prepend a + or - sign to the argument.  Points is
-assumed as the
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>,
-so there's no need to append a unit to the argument.  Fractional point
-sizes are allowed.
-<p>
-<ul>
-<li><strong>TITLE_SIZE</strong> <nobr>&lt;+/-points&gt;</nobr>
-<br>
-default = +3.5 (+4 if docheader title is &quot;Chapter #&quot;)

-Simply pass the appropriate macro the size adjustment you want.
-<p>
-
-<a name="CHANGE_ATTRIBUTE"><h3><u>8. Change the attribution string (&quot;by&quot;)</u></h3></a>
-<p>
-If you're not writing in English, you can change what
-<strong>mom</strong> prints where &quot;by&quot; appears in
-docheaders.  For example,
-<p>
-<pre>
-	.ATTRIBUTE_STRING "par"
-</pre>
-
-changes &quot;by&quot; to &quot;par&quot;.  If you
-don't want an attribution string at all, simply pass
-<strong>ATTRIBUTE_STRING</strong> an empty argument, like this:
-<p>
-<pre>
-	.ATTRIBUTE_STRING ""
-</pre>
-
-<strong>Mom</strong> will deposit a blank line where the
-attribution string normally appears.
-<p>
-<strong>NOTE:</strong> The type specs for the attribution line
-in docheaders are the same as for the author line.  Although
-it's highly unlikely you'll want the attribution line in a
-different family, font, or point size, you can do so by using
-<a href="definitions.html#TERMS_INLINES">inline escapes</a>
-in the argument to <strong>ATTRIBUTE_STRING</strong>.  For
-example,
-<p>
-<pre>
-	.ATTRIBUTE_STRING "\f[HBI]\*[SIZE -2p] by \*[SIZE +2p]\*[PREV]"
-</pre>
-
-would set &quot;by&quot; in Helvetica bold italic, 2 points
-smaller than normal.

-<!---COLUMNS_INTRO--->
-
-<a name="COLUMNS_INTRO"><h2><u>Setting documents in columns</u></h2></a>
-
-<p>
-Setting documents in columns is easy with <strong>mom</strong>.  (Of
-course she'd say that, but it's true!)  All you have to do is is
-say how many columns you want and how much space you want
-between them (the
-<a href="definitions.html#TERMS_GUTTER">gutters</a>).
-That's it. <strong>Mom</strong> takes care of everything else, from
-soup to nuts.
-<p>
-<strong>SOME WORDS OF ADVICE:</strong>
-<p>
-If you want your type to achieve a pleasing
-<a href="definitions.html#TERMS_JUST">justification</a>
-or
-<a href="definitions.html#TERMS_RAG">rag</a>
-in columns, reduce the point size of type (and probably the
-<a href="definitions.html#TERMS_LEADING">leading</a>
-as well).  <strong>Mom</strong>'s default document point
-size is 12.5, which works well across her default 39
-<a href="definitions.html#TERMS_PICASPOINTS">pica</a>
-full page line length, but with even just two columns on a page,
-the default point size is awkward to work with.
-<p>
-Furthermore, you'll absolutely need to reduce the indents for
-<a href="docelement.html#EPIGRAPH_CONTROL">epigraphs</a>,
-<a href="docelement.html#QUOTE_GENERAL">quotes</a>,
-and
-<a href="docelement.html#BLOCKQUOTE_GENERAL">blockquotes</a>
-(and probably the
-<a href="docelement.html#PARA_INDENT">paragraph first-line indent</a>
-as well).
-<p>

-<!---COLUMNS--->

-<a name="COLUMNS"><h3><u>COLUMNS</u></h3></a>
-<br>
-<nobr>Macro: <strong>COLUMNS</strong> &lt;number of columns&gt; &lt;width of gutters&gt;</nobr>
-<br>
-<em>*Should be the last macro before START
-<br>
-The second argument requires a <a href="#TERMS_UNITOFMEASURE">unit of measure</a></em>
-
-<p>
-<strong>COLUMNS</strong> takes two arguments: the number of
-columns you want on document pages, and the width of the
-<a href="definitions.html#TERMS_GUTTER">gutter</a>
-between them.  For example, to set up a page with two columns
-separated by an 18 point gutter, you'd do
-<p>
-<pre>
-	.COLUMNS 2 18p
-</pre>
-
-Nothing to it, really.  However, as noted above,
-<strong>COLUMNS</strong> should always be the last document
-setup macro prior to
-<a href="#START">START</a>.
-<p>
-<strong>NOTE:</strong> <strong>Mom</strong> ignores columns completely
-when the
-<a href="#PRINTSTYLE">PRINTSTYLE</a>
-is <strong>TYPEWRITE</strong>.	The notion of typewriter-style
-output in columns is just too ghastly for her to bear.

-<h3><u>Using tabs when COLUMNS are enabled</u></h3>

-(both
-<a href="typesetting.html#TYPESETTING_TABS">typesetting tabs</a>
-and
-<a href="typesetting.html#STRING_TABS">string tabs</a>)
-behave as you'd expect during document processing, even when
-<strong>COLUMNS</strong> are enabled.  Tab structures set up
-during document processing carry over from page to page and column
-to column.
-
-<a name="BREAKING_COLUMNS"></a>
-<h3><u>Breaking columns manually</u></h3>
-<strong>Mom</strong> takes care of breaking columns when they reach
-the bottom margin of a page.  However, there may be times you want to
-break the columns yourself.  There are two macros for breaking columns
-manually: <strong>COL_NEXT</strong> and <strong>COL_BREAK</strong>.
-
-<a name="COL_NEXT"></a>
-<p>
-<kbd>.COL_NEXT</kbd> breaks the line just before it,
-<a href="definitions.html#TERMS_QUAD">quads</a>
-it left (assuming the type is justified or quad left), and moves over
-to the top of the next column.  If the column happens to be the last
-(rightmost) one on the page, <strong>mom</strong> starts a new page
-at the &quot;column 1&quot; position.  This is the macro to use when
-you want to start a new column after the end of a paragraph.
-
-<a name="COL_BREAK"></a>
-<p>
-<kbd>.COL_BREAK</kbd> is almost the same, except that
-instead of breaking and quadding the line preceding it,
-she breaks and spreads it (see
-<a href="typesetting.html#SPREAD">SPREAD</a>).
-Use this macro whenever you need to start a new column in the middle
-of a paragraph.
-<p>
-If you need <strong>COL_BREAK</strong> in the middle of a blockquote
-or (god help us) an epigraph, you must do the following in order for
-<strong>COL_BREAK</strong> to work:
-<p>
-<pre>
-	.SPREAD
-	\!.COL_BREAK

-<hr width="66%" align="left">
-<a name="ALIAS"><h3><u>Rename macros</u></h3></a>
-<br>
-<nobr>Macro: <strong>ALIAS</strong> &lt;new name&gt; &lt;old name&gt;</nobr>
-
-<p>
-The <strong>ALIAS</strong> macro may well be your best friend.  With it,
-you can change the name of a macro to anything you like
-(provided the new name is not already being used by
-<strong>mom</strong>; see the
-<a href="reserved.html#RESERVED">list of reserved words</a>).
-<p>
-Groff has always been a bit intimidating for new users because
-its standard macro packages use very terse macro names.
-<strong>Mom</strong> doesn't like people to feel intimidated; she wants
-them to feel welcome.  Consequently, she tries for easy-to-grasp,
-self-explanatory macro names.  However, <strong>mom</strong> knows
-that people have their own ways of thinking, their own preferences,
-their own habits.  Some of her macro names may not suit you; they
-might be too long, or aren't what you automatically think of
-when you want to do a particular thing, or might conflict with habits
-you've developed over the years.
-<p>
-If you don't like one of <strong>mom</strong>'s macro names,
-say, PAGEWIDTH, change it, like this:
-<p>
-<pre>
-	.ALIAS PW PAGEWIDTH
-	       |      |
-	  new__|      |__official
-	 name            name
-</pre>
-
-The first argument to <strong>ALIAS</strong> is the new name you want
-for a macro.  The second is the &quot;official&quot; name by
-which the macro is normally invoked.  After <strong>ALIAS</strong>,
-either can be used.
-<p>
-Note that in <strong>ALIAS</strong>, you do NOT include the period
-(dot) that precedes the macro when it's a
-<a href="definitions.html#TERMS_CONTROLLINES">control line</a>.
-<p>
-<strong>NOTE:</strong> If you use <strong>ALIAS</strong> a lot,
-and always for the same things, consider creating an aliases
-file of the form
-<p>
-<pre>
-	.ALIAS &lt;new name&gt; &lt;old name&gt;
-	.ALIAS &lt;new name&gt; &lt;old name&gt;
-	.ALIAS &lt;new name&gt; &lt;old name&gt;
-	...etc
-</pre>
-
-Put the file someplace convenient and source it at the
-beginning of your documents using the groff
-<a href="definitions.html#TERMS_PRIMITIVES">primitive</a>
-<strong>.so</strong>.  Assuming that you've created an aliases file
-called mom_aliases in your home directory under a directory
-called <code>Mom</code>, you'd source it by placing
-<p>
-<pre>
-	.so /home/&lt;username&gt;/Mom/mom_aliases
-</pre>
-
-at the top of your documents.
-<p>
-If you share documents that make use of an alias file, remember that
-other people don't have the file!  Paste the whole thing at the top
-of your documents, please.
-<p>
-<strong>EXPERTS:</strong> <strong>ALIAS</strong> is an alias of
-<code>.als</code>.  You can use either, or mix 'n' match with
-impunity.
-<p>
-
-<!---SILENT--->
-
-<hr width="66%" align="left">
-<a name="SILENT"><h3><u>Hide input lines from output</u></h3></a>
-<br>
-<nobr>Macro: <strong>SILENT</strong> toggle</nobr>
-<br>
-Alias: <strong>COMMENT</strong>
-
-<p>
-Sometimes, you want to &quot;hide&quot;
-<a href="definitions.html#TERMS_INPUTLINE">input lines</a>
-from final output.  This is most likely to be the case when setting
-up string tabs (see the
-<a href="STRING_TABS_TUT">quickie tutorial on string tabs</a>
-for an example), but there are other places where you might want input
-lines to be invisible as well.  Any place you don't want input lines
-to appear in the output, use the <strong>SILENT</strong> macro.
-<p>
-<strong>SILENT</strong> is a toggle.  Invoking it without an argument
-turns it on; any argument turns it off.  E.g.,
-<p>
-<pre>
-	.SILENT
-	A line of text
-	.SILENT OFF
-</pre>
-
-The line &quot;A line of text&quot; will not appear in the
-output copy.
-<p>
-<strong>SILENT</strong> is aliased as <strong>COMMENT</strong>.
-If you want to insert non-printing comments into your documents,
-you may prefer this.
-<p>
-<strong>NOTE: SILENT</strong> does not automatically break an
-<a href="definitions.html#TERMS_INPUTLINE">input line</a>
-(see
-<a href="typesetting.html#BR">BR</a>)
-when you're in one of the
-<a href="definitions.html#TERMS_FILLED">fill modes</a>
-(<a href="typesetting.html#JUSTIFY">JUSTIFY</a>
-or
-<a href="typesetting.html#QUAD">QUAD L | R | C | J</a>).
-The same applies to tabs
-(<a href="typesetting.html#TAB_SET">typesetting</a>
-or
-<a href="typesetting.html#ST">string</a>)
-to which you've passed the <strong>J</strong> or <strong>QUAD</strong>
-argument.  You must insert <code>.BR</code> yourself, or risk a
-portion of your text disappearing into a black hole.
-<p>
-
-<!---TRAP--->
-
-<hr width="66%" align="left">
-<a name="TRAP"><h3><u>Suspend/re-invoke traps</u></h3></a>
-<br>
-<nobr>Macro: <strong>TRAP</strong> toggle</nobr>
-
-<p>
-Traps are vertical positions on the output page at which you or
-<strong>mom</strong> have instructed groff to start doing
-something automatically.  Commonly, this is near the bottom of
-the page, where automatic behind-the-scenes processing is needed
-in order for one page to finish and another to start.
-<p>
-Sometimes, traps get sprung when you don't want them.  If this
-happens, surround just the offending macros and input lines with
-<p>
-<pre>
-	.TRAP OFF
-	...
-	.TRAP
-</pre>
-
-<strong>TRAP</strong> is a toggle, therefore any argument 
-turns it off (i.e. suspends the trap), and no argument turns it
-(back) on.
-<p>
-
-<!---SMARTQUOTES--->
-
-<hr width="66%" align="left">
-<a name="SMARTQUOTES"><h3><u>Convert typewriter doublequotes to proper doublequotes</u></h3></a>
-<br>
-<nobr>Macro: <strong>SMARTQUOTES</strong> [&lt;off&gt;] [ ,, | &gt;&gt; | &lt;&lt; ]</nobr>
-<br>
-or
-<br>
-<nobr>Macro: <strong>SMARTQUOTES</strong> DA | DE | ES | FR | IT | NL | NO | PT | SV</nobr>
-
-<p>
-If you invoke <strong>SMARTQUOTES</strong> without an argument,
-<strong>mom</strong> converts all instances of the inch-mark,
-(<kbd>"</kbd> -- also called a &quot;doublequote&quot;), into
-the appropriate instances of true Anglo-American open- and
-close-doublequotes.  (See
-<a href="#SQ_INTERNATIONAL">Internationalization</a>
-for how to get SMARTQUOTES to behave correctly for non-English
-quoting styles.)
-<p>
-Typographically, there is a difference between the inch-mark and
-doublequotes -- a BIG difference.  Sadly, typewriters and computer
-keyboards supply only one: the inch-mark.  While using inches for
-doublequotes is, and always has been, acceptable in typewriter-style
-copy, it has never been, and, God willing, never will be acceptable in
-typeset copy.  Failure to turn inches into quotes is the first thing
-a professional typesetter notices in documents prepared by amateurs.
-And you don't want to look like an amateur, do you?
-<p>
-<a name="SQ_INTERNATIONAL"><h3>Internationalization</h3></a>
-<p>
-If you invoke <strong>SMARTQUOTES</strong> with one of the optional
-arguments (<kbd>,,</kbd> or <kbd>&gt;&gt;</kbd> or
-<kbd>&lt;&lt;</kbd>) you can use <kbd>&quot;</kbd> as &quot;cheap&quot;
-open- and close-quotes when inputting text in a language other than
-English, and have <strong>mom</strong> convert them, on output,
-into the chosen open- and close-quote style.
-<p>
-<kbd>,,</kbd> opens quotes with &quot;lowered doublequotes&quot; and
-closes them with &quot;raised doublequotes&quot;, as in this ascii
-approximation:
-<p>
-<pre>
-	,,Hilfe !``
-</pre>
-
-<kbd>&gt;&gt;</kbd> opens quotes with guillemets pointing to the
-right, and closes them with guillemets pointing to the left, as in
-this ascii approximation:
-<p>
-<pre>
-	&gt;&gt;Zurück !&lt;&lt;
-</pre>
-
-<kbd>&lt;&lt;</kbd> opens quotes with guillemets pointing to the
-left, and closes them with guillemets pointing to the right, as in
-this ascii approximation:
-<p>
-<pre>
-	&lt;&lt;Mais monsieur! Je ne suis pas ce genre de fille!&gt;&gt;
-</pre>
-
-Please note: the above arguments to <strong>SMARTQUOTES</strong>
-are literal ASCII characters. <kbd>,,</kbd> is two commas,
-<kbd>&lt;&lt;</kbd> is two less-than signs and <kbd>&gt;&gt;</kbd>
-is two greater-than signs.
-<p>
-Alternatively, you can pass <strong>SMARTQUOTES</strong> the
-two-letter, ISO 639 abbreviation for the language you're writing in,
-and <strong>mom</strong> will output the correct quotes.
-<p>
-<pre>
-	.SMARTQUOTES DA     = Danish      &gt;&gt;text&lt;&lt;
-	.SMARTQUOTES DE     = German      ,,text``
-	.SMARTQUOTES ES     = Spanish     ``text´´
-	.SMARTQUOTES FR     = French      &lt;&lt; text &gt;&gt;
-	.SMARTQUOTES IT     = Italian     &lt;&lt; text &gt;&gt;
-	.SMARTQUOTES NL     = Dutch       ´´text´´
-	.SMARTQUOTES NO     = Norwegian   &lt;&lt;text&gt;&gt;
-	.SMARTQUOTES PT     = Portuguese  &lt;&lt;text&gt;&gt;
-	.SMARTQUOTES SV     = Swedish     &gt;&gt;text&gt;&gt;
-</pre>
-<p>
-Turn <strong>SMARTQUOTES</strong> off by passing it any argument
-<em>not</em> in the argument list (e.g. <strong>OFF</strong>,
-<strong>QUIT</strong>, <strong>X</strong>, etc.)
-<p>
-If you're using the
-<a href="docprocessing.html#DOCPROCESSING">document processing macros</a>
-with
-<a href="#PRINTSTYLE">PRINTSTYLE TYPESET</a>,
-<strong>SMARTQUOTES</strong> is on by default (in the Anglo-American
-style); with
-<a href="#PRINTSTYLE">PRINTSTYLE TYPEWRITE</a>,
-it's off by default (and should probably stay that way).
-<p>
-Finally, if you're fussy about the kerning of quote marks in
-relation to the text they surround, or have special quoting needs,
-you have to enter quote marks by hand using groff's native
-<a href="definitions.html#TERMS_INLINES">inline escapes</a>
-for special characters (see man groff_char for a complete list of
-special characters).  Entering quote marks this way allows you to
-use <strong>mom</strong>'s
-<a href="inlines.html#INLINE_KERNING_MOM">inline kerning escapes</a>
-to fine-tune the look of quotes.
-<p>
-<strong>NOTE:</strong> <strong>SMARTQUOTES</strong> does not work on
-single quotes, which most people input with the apostrophe (found at
-the right-hand end of the &quot;home row&quot; on a QWERTY keyboard).
-Groff will interpret all instances of the apostrophe as an apostrophe,
-making the symbol useless as an open-single-quote.  For open single
-quotes, input the backtick character typically found under the tilde
-on most keyboards.  (Pour nous autres, &quot;backtick&quot; veut dire
-l'accent grave.)
-Here's an example of correct input copy with single quotes:
-<p>
-<pre>
-	"But she said, `I don't want to!'"	
-</pre>
-
-<strong>ADDITIONAL NOTE:</strong> Whether or not you have
-<strong>SMARTQUOTES</strong> turned on, get into the habit of entering
-the foot- and inch-marks, when you need them, with the
-<a href="definitions.html#TERMS_INLINES">inline escapes</a>
-<strong>\*[FOOT]</strong> and <strong>\*[INCH]</strong>, instead
-of <kbd>'</kbd> and <kbd>"</kbd>.
-<p>
-
-<!---CAPS--->
-
-<hr width="66%" align="left">
-<a name="CAPS"><h3><u>Convert to upper case</u></h3></a>
-<br>
-<nobr>Macro: <strong>CAPS</strong> toggle</nobr>
-
-<p>
-<strong>CAPS</strong> converts all lower case letters to upper
-case.  Primarily, it's a support macro used by the
-<a href="docprocessing.html#DOCPROCESSING">document processing macros</a>,
-but you may find it helpful on occasion.  <strong>CAPS</strong>
-is a toggle, therefore no argument turns it on, any argument
-turns it off.
-<p>
-<pre>
-	.CAPS
-	All work and no play makes Jack a dull boy.
-	.CAPS OFF
-</pre>
-
-produces, on output
-<p>
-<pre>
-	ALL WORK AND NO PLAY MAKES JACK A DULL BOY.
-</pre>
-
-<!---STRING--->
-
-<hr width="66%" align="left">
-<a name="STRING"><h3><u>User-defined strings</u></h3></a>
-<br>
-<nobr>Macro: <strong>STRING</strong> &lt;name&gt; &lt;what you want in the string&gt;</nobr>
-
-<p>
-You may find sometimes that you have to type out portions of text
-repeatedly.  If you'd like not to wear out your fingers, you can
-define a &quot;string&quot; that, whenever you call it by name,
-outputs whatever you put into it.
-<p>
-For example, say you're creating a document that repeatedly uses
-the phrase &quot;the Montreal/Windsor corridor&quot;.  Instead of
-typing all that out every time, you could define a string, like
-this:
-<p>
-<pre>
-	.STRING mw the Montreal/Windsor corridor
-</pre>
-
-Once a string is defined, you can call it any time with the
-<a href="definitions.html#INLINES">inline escape</a>
-<kbd>\*[&lt;stringname&gt;]</kbd>.  Using the example string above
-<p>
-<pre>
-	The schedule for trains along \*[mw]:
-</pre>
-
-produces, on output
-<p>
-<pre>
-	The schedule for trains along the Montreal/Windsor corridor:
-</pre>
-
-<strong>NOTE:</strong> Be very careful not to put any spaces at the
-ends of strings you're defining, unless you want them.  Everything
-after the name argument you pass to <strong>STRING</strong> goes
-into the string, including trailing spaces.
-<p>
-<strong>Experts: STRING</strong> is an alias for <strong>ds</strong>.
-You can use either, or mix 'n' match with impunity.
-<p>
-
-<!---UNDERSCORE--->
-
-<hr width="66%" align="left">
-<a name="UNDERSCORE"><h3><u>Single underscore</u></h3></a>
-<br>
-<nobr>Macro: <strong>UNDERSCORE</strong> [ &lt;distance below baseline&gt; ] &quot;&lt;string&gt;&quot;</nobr>
-<br>
-<em>*Optional argument requires a <a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a></em>
-
-<p>
-By default, <strong>UNDERSCORE</strong> places an underscore 2 points
-beneath the required
-<a href="definitions.html#TERMS_STRINGARGUMENT">string argument</a>.
-The string must be enclosed in double-quotes, like this:
-<p>
-<pre>
-	.UNDERSCORE "Unmonitored monopolies breed high prices and poor products."
-</pre>
-
-If you wish to change the distance of the rule from the
-baseline, use the optional argument <i>&lt;distance below
-baseline&gt;</i> (with a unit of measure).
-<p>
-<pre>
-	.UNDERSCORE 3p "Unmonitored monopolies breed high prices and poor products."
-</pre>
-
-The above places the underscore 3 points below the baseline.
-<p>
-<a name="NOTES_UNDERSCORE"></a>
-<strong>NOTES:</strong>
-<br>
-<strong>UNDERSCORE</strong> does not work across line breaks in output
-copy, which is to say that you can't underscore a multi-line passage
-simply by putting the text of the whole thing in the string you pass
-to <strong>UNDERSCORE</strong>.  Each
-<a href="definitions.html#TERMS_OUTPUTLINE">output line</a>
-or portion of an output line you want underscored must be plugged
-separately into <strong>UNDERSCORE</strong>.  Bear in mind, though,
-that underscoring should at best be an occasional effect in typeset
-copy.  If you want to emphasize an entire passage, it's much, much
-better to change fonts (e.g. to italic or bold).
-<p>
-You can easily and successfully underline entire passages in simulated
-typewriter-style copy (i.e. if your font is Courier, or you're using
-the document processing macro
-<a href="#PRINTSTYLE">PRINTSTYLE TYPEWRITE</a>),
-with the
-<a href="#UNDERLINE">UNDERLINE</a>
-macro.  <strong>UNDERLINE</strong> is designed specifically for this
-purpose, but works only with the Courier font.
-<p>
-<strong>Mom</strong> doesn't always get the position and length
-of the underscore precisely right in
-<a href="definitions.html#TERMS_JUST">justified</a>
-copy, although she's fine with all the other
-<a href="definitions.html#TERMS_FILLED">fill modes</a>,
-as well as with the no-fill modes.  As of this writing, I have
-no solution to the occasional problems with justified copy.
-<p>
-<strong>UNDERSCORE</strong> tends to confuse
-<strong>gxditview</strong>, even though the output, when
-printed, looks fine.  Generally, I recommend using <strong>gv</strong>
-to preview files anyway.  See the section on
-<a href="#PREVIEWING">previewing</a>.

-By default, <strong>UNDERSCORE2</strong> places a double underscore

-
-The default distance between the two rules is 2 points.

-If you wish to change the distance of the double underscore from

-<p>
-<pre>
-	.UNDERSCORE2 3p "Unmonitored monopolies breed high prices and poor products."

-<hr width="66%" align="left">
-<a name="PAD"><h3><u>Insert space into lines</u></h3></a>
-<br>
-<nobr>Macro: <strong>PAD</strong> &quot;&lt;string with pad markers inserted&gt;&quot; [NOBREAK]</nobr>
-
-<p>
-With <strong>PAD</strong>, you can insert unspecified amounts of
-whitespace into a line.  The optional <strong>NOBREAK</strong>
-argument tells <strong>mom</strong> not to advance on the page
-after the <strong>PAD</strong> macro has been invoked.
-<p>
-<strong>PAD</strong> calculates the difference between the length of
-text on the line and the distance remaining to its end, then inserts
-the difference (as whitespace) at the place(s) you specify.
-<p>
-Take, for example, the following relatively common typesetting
-situation, found at the bottom of legal agreements:
-<p>
-<pre>
-	Date             Signature                               |
-</pre>
-
-The person signing the agreement is supposed to fill in the date
-as well as a signature.  Space needs to be left for both, but
-the exact amount is neither known, nor important.  All that
-matters is that there be a little space after Date, and rather
-more space after Signature.  (In the above, | represents
-the end of the line at the prevailing line length.)
-<p>
-The
-<a href="#PADMARKER">pad marker</a>
-(see below) is # (the pound or number sign on your keyboard) and
-can be used multiple times in a line.  With that in mind, here's how
-you'd input the Date/Signature line (assuming a length of 30 picas):
-<p>
-<pre>
-	.LL 30P
-	.PAD "Date#Signature###"
-</pre>
-
-When the line is output, the space remaining on the line, after
-&quot;Date&quot; and &quot;Signature&quot; have been taken into
-account, is split into four (because there are four # signs).
-One quarter of the space is inserted between Date and Signature,
-the remainder is inserted after Signature.
-<a name="PAD_EXAMPLE"></a>
-<p>
-One rarely wants merely to insert space in a line; one usually
-wants to fill it with something, hence <strong>PAD</strong> is
-particularly useful in conjunction with
-<a href="#STRING_TABS">string tabs</a>.
-The following uses the Date/Signature example above, but adds
-rules into the whitespace through the use of string tabs and
-<strong>mom</strong>'s
-<a href="definitions.html#TERMS_INLINES">inline escape</a>
-<a href="inlines.html#INLINE_RULE_MOM">\*[RULE]</a>.
-(Instead of <strong>\*[RULE]</strong>,
-groff's line drawing function,
-<a href="inlines.html#INLINE_LINEDRAWING_GROFF">\l</a>
-could be used.)
-<p>
-<pre>
-	.LL 30P
-	.PAD "Date \*[ST1]#\*[ST1X] Signature \*[ST2]###\*[ST2X]" NOBREAK
-	.ST 1 J
-	.ST 2 J
-	.TAB 1
-	\*[RULE]
-	.TN
-	\*[RULE]
-	.TQ
-</pre>
-
-If you're not a typesetter, and if you're new to groff, the
-example probably looks like gibberish.  My apologies.  However,
-remember that typesetting is a craft, and without having studied
-the craft, it takes a while to grasp its concepts.
-<p>
-Basically, what the example does is:
-<br>
-<ol>
-	<li>Pads the Date/Signature line (using the pad marker #),
-		encloses the padded space with two string tabs markers,
-		and outputs the line.
-	<br>
-	<li>Sets the two string tabs (notice the use of
-		<a href="#EL">EL</a>
-		beforehand; you don't want <strong>mom</strong>
-		to advance a line at this point).
-	<br>
-	<li>Calls the first string tab and draws a rule to its full
-		length.
-	<br>
-	<li>Calls the second tab with
-		<a href="#TN">TN</a>
-		(which moves to tab 2 and stays on the same baseline)
-		then draws a rule to the full length of string tab 2.
-</ol>
-<br>
-Often, when setting up string tabs this way, you don't want the
-padded line to print immediately.  To accomplish this, use
-<a href="#SILENT">SILENT</a>.
-See the <a href="#STRING_TABS_TUT">quickie tutorial on string tabs</a>
-for an example.
-<p>
-<strong>NOTE:</strong> Because the pound sign (#) is used as the pad
-marker, you can't use it as a literal part of the pad string.  If you
-need the sign to appear in the text of a padded line, change the pad
-marker with <a href="#PAD_MARKER">PAD_MARKER</a>.  Also, be aware
-that # as a pad marker only applies within the <strong>PAD</strong>
-macro; at all other times it prints literally, just as you'd expect.
-<p>
-Another important consideration when using <strong>PAD</strong> is that
-because the string must be enclosed in double-quotes, you can't use the
-double-quote (&quot;) as part of the string.  The way to circumvent
-this is to use the groff
-<a href="definitions.html#TERMS_INLINES">inline escapes</a>
-<strong>\(lq</strong> and <strong>\(rq</strong> (leftquote and
-rightquote respectively) whenever double-quotes are required in the
-string passed to <strong>PAD</strong>.

-
-<p>
-If you need to change <strong>mom</strong>'s default pad marker

-<a name="LEADER"><h3><u>Inline escape to add leaders to a line</u></h3></a>
-<br>
-Inline: <strong>\*[LEADER]</strong>
-
-<p>
-Whenever you want to fill a line or tab with
-<a href="definitions.html#TERMS_LEADER">leaders</a>,
-use the
-<a href="definitions.html#TERMS_INLINES">inline escape</a>
-<strong>\*[LEADER]</strong>.  The remainder of the line or tab will be
-filled with the leader character.  <strong>Mom</strong>'s
-default leader character is a period (dot), but you can change
-it to any character you like with
-<a href="#LEADER_CHARACTER">LEADER_CHARACTER</a>.
-<p>
-<strong>NOTE:</strong> <strong>\*[LEADER]</strong> fills lines
-or tabs right to their end.  You cannot insert leaders into a
-line or tab and have text following the leader on the same line
-or in the same tab.  Should you wish to achieve such an effect
-typographically, create tabs for each element of the line and
-fill them appropriately with the text and leaders you need.
-<a href="#STRING_TABS">String tabs</a> are perfect for this.  An
-example follows.
-<p>
-<pre>
-	.LL 30P
-	.PAD "Date\*[ST1]#\*[ST1X]Signature\*[ST2]###\*[ST2X]"
-	.EL
-	.ST 1 J
-	.ST 2 J
-	.TAB 1
-	\*[LEADER]
-	.TN
-	\*[LEADER]
-	.TQ
-</pre>
-
-The <strong>PAD</strong> line sets the words Date and Signature,
-and marks string tabs around the pad space inserted in the line.
-The string tabs are then &quot;set&quot;, called, and filled
-with leaders.  The result looks like this:
-<p>
-<pre>
-	Date.............Signature.....................................

-<br>
-<nobr>Macro: <strong>DROPCAP</strong> &lt;dropcap letter&gt; &lt;number of lines to drop&gt; [ COND &lt;percentage&gt; | EXT &lt;percentage&gt; ]</nobr>
-
-<p>
-The first two arguments to <strong>DROPCAP</strong> are the letter you
-want to be the
-<a href="definitions.html#TERMS_DROPCAP">drop cap</a>
-and the number of lines you want it to drop.  By default,
-<strong>mom</strong> uses the current family and font for the drop cap.
-<p>
-The optional argument (COND or EXT) indicates that you want the
-drop cap condensed (narrower) or extended (wider).  If you use
-<strong>COND</strong> or <strong>EXT</strong>, you must follow the
-argument with the percentage of the letter's normal width you want
-it condensed or extended.  No percent sign (%) is required.
-<p>
-<strong>Mom</strong> will do her very best to get the drop cap to
-line up with the first line of text indented beside it, then set
-the correct number of indented lines, and restore your left margin
-when the number of drop cap lines has been reached.
-<p>
-Beginning a paragraph with a drop cap &quot;T&quot; looks
-like this:
-<p>
-<pre>
-	.DROPCAP T 3 COND 90
-	he thousand injuries of Fortunato I had borne as best I
-	could, but when he ventured upon insult, I vowed revenge.
-	You who so well know the nature of my soul will not suppose,
-	however, that I gave utterance to a threat...
-</pre>
-
-The drop cap, slightly condensed but in the current family and font,
-will be three lines tall, with whatever text fills those three
-lines indented to the right of the letter.  The remainder of the
-paragraph's text will revert to the left margin.
-<p>
-<strong>NOTE:</strong> When using the
-<a href="docprocessing.html#DOCPROCESSING">document processing macro</a>
-<a href="#PP">PP</a>,
-<strong>DROPCAP</strong> only works
-<br>
-<ul>
-	<li>with initial paragraphs (i.e. at the start of the document,
-		or after
-		<a href="#HEAD">HEAD</a>),
-	<li>when <strong>DROPCAP</strong> comes immediately after <strong>PP</strong>,
-	<li>and when the
-		<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE</a>
-		is TYPESET.
-</ul>
-<br>
-If these conditions aren't met, <strong>DROPCAP</strong> is silently ignored.
-<p>
-<strong>WARNING:</strong> <strong>DROPCAP</strong> puts a bit of
-a strain on resource-challenged systems.  If you have such a
-system and use drop caps extensively in a document, be prepared
-for a wait while <strong>mom</strong> does her thing.
-
-<h3><a name="DROPCAP_SUPPORT"><u>Support macros for DROPCAP</u></a></h3>
-Drop caps are the bane of most typesetters' existence.  It's
-very difficult to get the size of the drop cap right for the
-number of drop lines, especially if the drop cap is in a
-different family from the prevailing family of running text.
-Not only that, but there's the gutter around the drop cap to
-take into account, plus the fact that the letter may be too wide
-or too narrow to look anything but odd or misplaced.
-<p>
-<strong>Mom</strong> solves the last of these problems with the
-<strong>COND</strong> and <strong>EXT</strong> arguments.  The
-rest she solves with macros that change the default behaviour of
-<strong>DROPCAP</strong>, namely
-<p>
-<a href="#DROPCAP_FAMILY">DROPCAP_FAMILY</a>,
-<br>
-<a href="#DROPCAP_FONT">DROPCAP_FONT</a>,
-<br>
-<a href="#DROPCAP_COLOR">DROPCAP_COLOR</a>,

-<a href="#DROPCAP_ADJUST">DROPCAP_ADJUST</a>
-<br>
-and
-<br>
-<a href="#DROPCAP_GUTTER">DROPCAP_GUTTER</a>.
-<p>
-These macros must, of course, come before you invoke
-<strong>DROPCAP</strong>.
-
-<h3><a name="DROPCAP_FAMILY"><u>DROPCAP_FAMILY</u></a></h3>
-
-Set the drop cap family by giving
-<strong>DROPCAP_FAMILY</strong> the name of the family you want,
-e.g.
-<p>
-<pre>
-	.DROPCAP_FAMILY H
-</pre>
-
-which will set the family to Helvetica for the drop cap only.
-
-<h3><a name="DROPCAP_FONT"><u>DROPCAP_FONT</u></a></h3>
-
-Set the drop cap font by giving
-<strong>DROPCAP_FONT</strong> the name of the font you want,
-e.g.
-<p>
-<pre>
-	.DROPCAP_FONT I
-</pre>
-
-which will set the font to italic for the drop cap only.
-
-<h3><a name="DROPCAP_ADJUST"><u>DROPCAP_ADJUST</u></a></h3>
-
-If the size <strong>mom</strong> calculates for the drop cap
-isn't precisely what you want, you can increase or decrease it
-with <strong>DROPCAP_ADJUST</strong>, like this:
-e.g.
-<p>
-<pre>
-	.DROPCAP_ADJUST +1
-	    or
-	.DROPCAP_ADJUST -.75
-</pre>
-
-<strong>DROPCAP_ADJUST</strong> only understands
-<a href="definitions.html#TERMS_PICASPOINTS">points</a>,
-therefore do not append any
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-to the argument.  And always be sure to prepend the plus or
-minus sign, depending on whether you want the drop cap larger or
-smaller.
-
-
-<h3><a name="DROPCAP_COLOR"><u>DROPCAP_COLOR</u></a></h3>
-
-If you'd like your drop cap colourized, simply invoke
-<strong>DROPCAP_COLOR</strong> with the name of a colour you've already
-created (&quot;initialized&quot;) with
-<a href="color.html#NEWCOLOR">NEWCOLOR</a>
-or
-<a href="color.html#XCOLOR">XCOLOR</a>.  Only the drop cap will be
-colourized; all other text will remain at the current colour
-default (usually black).
-
-<h3><a name="DROPCAP_GUTTER"><u>DROPCAP_GUTTER</u></a></h3>
-
-By default, <strong>mom</strong> puts three points of space
-between the drop cap and the text indented beside it.  If you
-want another value, use <strong>DROPCAP_GUTTER</strong> (with a
-unit of measure), like this:
-<p>
-<pre>
-	.DROPCAP_GUTTER 6p
-</pre>
-

-<p>
-The superscript inlines are primarily used by the

-<strong>NOTE:</strong> <strong>Mom</strong> does a pretty fine job of

-And sorry, there's no <strong>mom</strong> equivalent for subscripts.

-unless otherwise noted, descriptions of headers
-describe footers as well.
-<p>
-Furthermore, any
-<a href="definitions.html#TERMS_CONTROLMACRO">control macro</a>
-that begins with <strong>HEADER_</strong> may be used to control
-footers, simply by replacing <strong>HEADER_</strong> with
-<strong>FOOTER_</strong>.
-<p>
-<strong>Author's note:</strong> Left to their own devices (i.e. if
-you're happy with the way <strong>mom</strong> does things by default),
-headers are something you never have to worry about.  You can skip
-reading this section entirely.  But if you want to change them, be
-advised that headers have more macros to control their appearance than
-any other document element.  The text of this documentation becomes
-correspondingly dense at this point.
-<a name="PAGINATION_NOTE"></a>
-<p>
-<strong>NOTE:</strong> While the single page number that
-<strong>mom</strong> generates in either the top or bottom margin
-above or below running text is technically a kind of header/footer,
-<strong>mom</strong> and this documentation treat it as a
-separate page element.
-<p>
-
-<a name="DESCRIPTION_GENERAL"><h3><u>General description of headers/footers</u></h3></a>
-<p>
-Headers comprise three distinct parts: a left part, a centre part,
-and a right part.  Each part contains text (a &quot;string&quot;)
-that identifies some aspect of the document as a whole.
-<p>
-The left part (&quot;header left&quot;) lines up with the document's
-left margin.  The centre part (&quot;header centre&quot;) is
-centred on the document's line length.  The right part (&quot;header
-right&quot;) lines up with the document's right margin.  Not all parts
-need contain a string, and if you don't want headers at all, you can
-turn them off completely.
-<p>
-<strong>A note to groff experts:</strong> Although
-<strong>mom</strong>'s headers resemble the three-part titles generated
-by <code>.tl</code>, they're in no way related to it, nor based
-upon it.  <code>.tl</code> is not used at all in <strong>mom</strong>.
-<p>
-Normally, <strong>mom</strong> fills headers with strings appropriate
-to the document type selected with
-<a href="docprocessing.html#DOCTYPE">DOCTYPE</a>.
-You can, however, supply whatever strings you like -- including page
-numbers -- to go in any part of headers.  What's more, you can set the
-family, font, size and capitalization style (caps or caps/lower-case)
-for each header part individually.
-<p>
-By default, <strong>mom</strong> prints a horizontal rule beneath
-headers to separate them visually from running text.  In the case of
-footers, the rule is <em>above</em> running text.  You can increase
-or decrease the space between the header and the rule if you like (with
-<a href="#HDRFTR_RULE_GAP">HEADER_RULE_GAP</a>),
-or remove it completely.
-<p>
-
-<a name="HEADER_STYLE"><h3><u>Default specs for headers/footers</u></h3></a>
-<p>
-<strong>Mom</strong> makes small type adjustments to each part of
-the header (left, centre, right) to achieve an aesthetically
-pleasing result.  The defaults are listed below.  (The strings
-<strong>mom</strong> puts by default in each part are explained in
-<a href="docprocessing.html#DOCTYPE">DOCTYPE</a>.)
-<p>
-<strong>NOTE:</strong> Except for capitalization (all caps or
-caps/lower-case), these defaults apply only to
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE TYPESET</a>.
-<p>
-<pre>
-TYPE SPEC    HEADER LEFT         HEADER CENTER       HEADER RIGHT
----------    -----------         -------------       ------------
-Family       document default    document default    document default
-Font         roman               italic              roman
-Colour       (black)             (black)             (black)
-All caps     no                  no                  yes
-Size*        -.5 (points)        -.5 (points)        -2 (points)
-            (-2 if all caps)    (-2 if all caps)    (-.5 if not all caps)
-
-*Relative to the point size of type in paragraphs
-</pre>
-
-You can, of course, change any of the defaults using the appropriate
-control macros.  And should you wish to design headers from the ground
-up, <strong>mom</strong> has a special macro,
-<a href="#HDRFTR_PLAIN">HEADER_PLAIN</a>,
-that removes all type adjustments to headers.  The straightforward
-type specs for paragraphs are used instead, providing a simple
-reference point for any alterations you want to make to the family,
-font, size and capitalization style of any header part.
-<p>
-
-<a name="VERTICAL_SPACING"><h3><u>Vertical placement and spacing of headers/footers</u></h3></a>
-<p>
-As explained in the section on
-<a href="typedocmac.html">typesetting macros in document processing</a>,
-the top and bottom margins of a <strong>mom</strong> document
-are the vertical start and end positions of
-<a href="definitions.html#TERMS_RUNNING">running text</a>,
-not the vertical positions of headers or footers, which, by definition,
-appear in the margins <em>above</em> (or below) running text.
-<p>
-The vertical placement of headers
-is controlled by the macro
-<a href="#HDRFTR_MARGIN">HEADER_MARGIN</a>,
-which establishes the
-<a href="definitions.html">baseline</a>
-position of headers relative to the <em>top</em> edge of the page.
-The header rule, whose position is relative to the header itself,
-is controlled by a separate macro.
-<strong>FOOTER_MARGIN</strong> establishes the baseline position of
-footers relative to the <em>bottom</em> edge of the page.
-<p>
-<a href="#HDRFTR_GAP">HEADER_GAP</a> establishes
-the distance between headers and the <em>start</em> of running text (effectively
-making <strong>HEADER_MARGIN + HEADER_GAP</strong> the top margin of
-running text unless you give <strong>mom</strong> a literal top margin
-(with
-<a href="typesetting.html#T_MARGIN">T_MARGIN</a>),
-in which case she ignores <strong>HEADER_GAP</strong> and starts
-running text at whatever top margin you gave.
-<strong>FOOTER_GAP</strong> and
-<a href="typesetting.html#B_MARGIN">B_MARGIN</a>
-work similarly, except they determine where running text
-<em>ends</em> on the page.  (See
-<a href="#FOOTER_MARGIN">FOOTER MARGIN AND BOTTOM MARGIN -- VERY IMPORTANT!</a>
-for a warning about possible conflicts between the footer margin
-and the bottom margin.)
-<p>
-Confused?  <strong>Mom</strong> apologizes.  It's really quite
-simple.  By default, <strong>mom</strong> sets headers 4-1/2
-<a href="definitions.html#TERMS_PICASPOINTS">picas</a>
-down from the top of the page and starts running text 3 picas (the
-<strong>HEADER_GAP</strong>) beneath that, which means the
-effective top margin of running text is 7-1/2 picas (visually approx. 1
-inch).  If you give <strong>mom</strong> a literal top margin (with
-<a href="typesetting.html#T_MARGIN">T_MARGIN</a>),
-she ignores the <strong>HEADER_GAP</strong> and starts running
-text at whatever top margin you gave.
-<p>
-Footers are treated the same way, the only difference being the
-default distances.  <strong>Mom</strong> sets footers 3 picas up from
-the bottom of the page, and interrupts the processing of running text 3
-picas (the <strong>FOOTER_GAP</strong>) above that (again, visually
-approx. 1 inch).  If you give <strong>mom</strong> a literal bottom
-margin (with <a
-href="typesetting.html#B_MARGIN">B_MARGIN</a>), she ignores the
-<strong>FOOTER_GAP</strong> and interrupts the processing of running
-text at whatever bottom margin you gave.
-<p>
-If <strong>mom</strong> is paginating your document (she
-does, by default, at the bottom of each page), the vertical
-spacing and placement of page numbers, whether at the top
-or the bottom of the page, is managed exactly as if the
-page numbers were headers (or footers), and are controlled
-by the same macros.  See
-<a href="#PAGINATION">Pagination control</a>.

-<p>
-The following are the basic macros for turning

-or
-<a href="definitions.html#TERMS_FOOTER">footers</a>
-on or off.  They should be invoked prior to
-<a href="docprocessing.html#START">START</a>.
-<p>
-By default, <strong>mom</strong> prints page headers.  If you turn
-them off, she will begin
-<a href="definitions.html#TERMS_RUNNING">running text</a>
-on each page with a default top margin of 6
-<a href="definitions.html#TERMS_PICASPOINTS">picas</a>
-unless you have requested a different top margin (with
-<a href="typesetting.html#T_MARGIN">T_MARGIN</a>)
-prior to
-<a href="docprocessing.html#START">START</a>.
-<p>
-Please note that headers and footers are mutually exclusive.  If
-headers are on, footers (but NOT bottom-of-page numbering) are
-automatically turned off.  Equally, if footers are on, headers
-(but NOT top-of-page numbering) are automatically turned off.  Thus, if
-you'd prefer footers in a document, you need only invoke
-<a href="#FOOTERS">FOOTERS</a>;
-there's no need to turn headers off first.

-
-With <strong>mom</strong>'s standard 3-part headers, this isn't
-possible, even when
-<a href="rectoverso.html#RECTO_VERSO">RECTO_VERSO</a>
-is enabled.  <strong>RECTO_VERSO</strong> switches the left and
-right parts of headers on alternate pages, but the centre
-part remains unchanged.
-<p>
-Any time you need distinctly different headers on alternate
-pages, <strong>mom</strong> has macros that let you manually
-design and determine what goes into headers on recto pages, and
-what goes into headers on verso pages.  The macros are
-<a href="#HDRFTR_RECTO">HEADER_RECTO</a>
-and
-<a href="#HDRFTR_VERSO">HEADER_VERSO</a>.
-Both allow you to state whether the header is flush left, centred,
-or flush right, and both take a single
-<a href="definitions.html#TERMS_STRINGARGUMENT">string argument</a>
-with which, by combining text and
-<a href="definitions.html#TERMS_INLINES">inline escapes</a>,
-you can make the headers come out just about any way you want.
-Use of the <strong>\*[PAGE#]</strong> escape is permitted in the
-string argument (see
-<a href="#PAGE_NUMBER_INCL">Including the page number in header-left, -centre or -right</a>),
-and as an added bonus, <strong>mom</strong> provides a special
-mechanism whereby it's possible to &quot;pad&quot; the string as well.

-<br>
-<nobr>Macro: <strong>HEADER_VERSO</strong> LEFT | CENTER | RIGHT &quot;&lt;header verso string&gt;&quot;</nobr>
-<br>
-
-<p>
-<strong>HEADER_RECTO</strong> and <strong>HEADER_VERSO</strong> behave
-identically, hence all references to <strong>HEADER_RECTO</strong>
-in this section also refer to <strong>HEADER_VERSO</strong>.
-Furthermore, <strong>FOOTER_</strong> can be used instead of
-<strong>HEADER_</strong> to set up recto/verso footers.
-<p>
-The first argument to <strong>HEADER_RECTO</strong> is the
-direction in which you want the header
-<a href="definitions.html#TERMS_QUAD">quadded</a>.
-<strong>L, C</strong> and <strong>R</strong> may be used in
-place of <strong>LEFT, CENTER</strong> and
-<strong>RIGHT</strong>.  The second argument is a string,
-surrounded by double-quotes, containing what you want in the
-header.  <strong>HEADER_RECTO</strong> disables <strong>mom</strong>'s
-normal 3-part headers, therefore anything you want in the
-headers must be entered by hand in the string, including colours
-(via the
-<a href="definitions.html#TERMS_INLINES">inline escape</a>
-<a href="color.html#COLOR_INLINE">\*[&lt;colorname&gt;]</a>).
-<p>
-By default, <strong>HEADER_RECTO</strong> is set at the same
-size, and in the same family and font, as paragraph text.  The
-control macros
-<a href="#HDRFTR_GLOBAL_FAMILY">HEADER_FAMILY</a>
-and
-<a href="#HDRFTR_GLOBAL_SIZE">HEADER_SIZE</a>
-may be used to change the default family and size.  Changes to
-the font(s) within the string must be accomplished with the
-<a href="definitions.html#TERMS_INLINES">inline escapes</a>
-<strong>\*[ROM], \*[IT], \*[BD], \*[BDI]</strong> and
-<strong>\*[PREV]</strong> (see
-<a href="inlines.html#INLINE_FONTS_MOM">Changing fonts</a>).
-Additional refinements to the style of the header-recto string,
-including horizontal spacing and/or positioning, can also be made with
-inline escapes.

-To include the current page number in the string, use the
-<strong>\*[PAGE#]</strong> inline.

-
-To pad the string argument passed to <strong>HEADER_RECTO</strong>,
-begin and end the string (inside the double-quotes) with the caret
-character (<kbd>^</kbd>).  Enter the pound sign (<kbd>#</kbd>) at any
-point in the string where you want an equalized amount of whitespace
-inserted.  (If you're unsure what padding is, see
-<a href="goodies.html#PAD">Insert space into lines</a>.)
-Note that if you're padding the string, it doesn't matter what
-quad direction you give <strong>HEADER_RECTO</strong> since
-padding, by its nature, justifies text to the left and right
-margins.
-<p>
-The situation depicted above is accomplished like this:
-<p>
-<pre>
-	.HEADER_RECTO LEFT "^\*[PAGE#]#Title^"
-	.HEADER_VERSO LEFT "^Author#\*[PAGE#]^"
-</pre>
-
-Note that <strong>mom</strong> does not interpret the <kbd>#</kbd>
-in <strong>\*[PAGE#]</strong> as a padding marker (i.e. as a place
-to insert whitespace).
-<p>
-Also, notice that the argument <strong>LEFT</strong> is used in both
-cases.  When padding a header, it doesn't matter whether you use
-LEFT, CENTER or RIGHT as the argument.
-<p>
-Furthermore, should you need a user-defined header of
-the sort provided by <strong>HEADER_RECTO</strong> and
-<strong>HEADER_VERSO</strong> but aren't actually printing
-recto/verso, you can use <strong>HEADER_RECTO</strong> to design the
-header that appears at the top of every page.
-<p>
-<strong>IMPORTANT:</strong> The
-<a href="goodies.html#PAD_MARKER">PAD_MARKER</a>
-macro, which changes the default pad marker (<kbd>#</kbd>) used by
-<a href="goodies.html#PAD">PAD</a>,
-has no effect on the pad marker used in the
-<strong>HEADER_RECTO</strong> string.  If you absolutely must
-have a literal pound sign in your <strong>HEADER_RECTO</strong>
-string, use the escape sequence for the pound sign
-(<kbd>\[sh]</kbd>) where you want the pound sign to go.

-To change the text (the &quot;string&quot;) of the left, centre,
-or right part of headers, invoke the appropriate macro above with
-the string you want.  For example, <strong>mom</strong>, by default,
-prints the document's author in the header-left position.  If your
-document has, say, two authors, and you want both their names to
-appear header-left, change <strong>HEADER_LEFT</strong> like this:
-<p>
-<pre>
-	.HEADER_LEFT "R. Stallman, E. Raymond"
-</pre>
-
-Because the arguments to <strong>HEADER_LEFT, _CENTER,</strong>
-and <strong>_RIGHT</strong> are
-<a href="definitions.html#TERMS_STRINGARGUMENT">string arguments</a>,
-they must be enclosed in double-quotes.
-<p>
-<strong>NOTE:</strong> Replace <strong>HEADER_</strong>, above,
-with <strong>FOOTER_</strong> to change the strings in footers.
-
-<a name="HDRFTR_CENTER_PAD"><h3><u>*Padding the header/footer centre string</u></h3></a>
-<p>
-<nobr>Macro: <strong>HEADER_CENTER_PAD</strong> LEFT | RIGHT &lt;amount of space by which to pad centre string left or right&gt;</nobr>
-<br>
-<em>*Requires a <a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a></em>
-<p>
-By default, <strong>mom</strong> centres the header centre string
-literally on the line length in effect for page headers.  In some
-cases, notably when the header left or header right strings are
-particularly long, the effect isn't pretty.  The offendingly long
-header left or right crowds, or even overprints, the header centre.
-That's where <strong>HEADER_CENTER_PAD</strong> comes in.  With a
-bit of experimentation (yes, you have to preview the document), you
-can use <strong>HEADER_CENTER_PAD</strong> to move the header
-centre string left or right until it looks acceptably centred
-between the two other strings.
-<p>
-For example, say your document is an outline for a novel called "By
-the Shores of Lake Attica."  You've told <strong>mom</strong>
-you want
-<p>
-&nbsp;&nbsp;&nbsp;&nbsp;<a href="docprocessing.html#DOCTYPE">DOCTYPE</a>
-<halign="center">
-<strong>NAMED</strong> "Outline"
-<p>
-but when you preview your work, you see that "Outline", in the
-centre of the page header, is uncomfortably close to the title,
-which is to the right of it.  By invoking
-<p>
-<pre>
-	.HEADER_CENTER_PAD RIGHT 3P
-</pre>
-
-you can scoot the word "Outline" over three
-<a href="definitions.html#TERMS_PICASPOINTS">picas</a>
-to the left (the padding's added to the right of the string)
-so that your head looks nicely spaced out.  Invoking
-<strong>HEADER_CENTER_PAD</strong> with the <strong>LEFT</strong>
-argument obviously puts the padding on the left side of the string.
-<p>
-Most reassuring of all is that if you use
-<strong>HEADER_CENTER_PAD</strong> conjunction with
-<a href="rectoverso.html#RECTO_VERSO">RECTO_VERSO</a>,
-<strong>mom</strong> will pad the centre string appropriately left
-OR right, depending on which page you're on, without you having to
-tell her to do so.

-<p>
-<a name="RESERVED_STRINGS"><h3><u>Using mom's &quot;reserved&quot; strings in header/footer definitions</u></h3></a>
-<p>
-As pointed out in the author's note in the introduction to
-headers/footers, headers and footers are something you don't
-normally have to worry much about.  <strong>Mom</strong> usually
-knows what to do.
-<p>
-However, situations do arise where you need to manipulate what goes
-in the header/footer strings, setting and resetting them as you go
-along.  A case where you might want to do this would be if you want
-to output endnotes at the end of each document in a series of
-<a href="rectoverso.html#COLLATE">collated</a>
-documents, and you want the word "Endnotes" to go in the header
-centre position of the endnotes, but want, say, the
-<a href="docprocessing.html#TITLE">TITLE</a>
-to go back into the centre position for the next output document.
-<p>
-In scenarios like the above, <strong>mom</strong> has a number of
-&quot;reserved&quot; strings that you can plug into the
-<strong>HEADER_LEFT, _CENTER</strong> and <strong>_RIGHT</strong>
-macros.  They are:
-<p>
-<pre>
-	\*[$TITLE]          -- the argument passed to .TITLE
-	\*[$DOCTITLE]       -- the argument passed to .DOCTITLE
-	\*[$AUTHOR_1]       -- the first argument passed to .AUTHOR
-	\*[$CHAPTER_STRING] -- the argument passed to .CHAPTER_STRING,
-	                       if invoked, otherwise, "Chapter"
-	\*[$CHAPTER]        -- the argument (typically a number) passed
-	                       to .CHAPTER
-	\*[$CHAPTER_TITLE]  -- the argument passed to .CHAPTER_TITLE
-</pre>
-
-Returning to the scenario above, first, you'd define a centre
-string for the endnotes page:
-<p>
-<pre>
-	.HEADER_CENTER "Endnotes"
-</pre>
-
-Then, you'd output the endnotes:
-<p>
-<pre>
-	.ENDNOTES
-</pre>
-
-Then, you'd prepare <strong>mom</strong> for the next document:
-<p>
-<pre>
-	.COLLATE
-	.TITLE "New Doc Title"
-	.AUTHOR "Josephine Blough"
-</pre>
-
-Then, you'd redefine the header centre string using the reserved
-string \*[$TITLE], like this:
-<p>
-<pre>
-	.HEADER_CENTER "\*[$TITLE]"
-</pre>
-
-And last, you'd do:
-<p>
-<pre>
-	.START
-</pre>
-
-Voilà!  Any argument you pass to <strong>TITLE</strong> from here
-on in (say, for subsequent documents) is back in the header centre
-position.  Here's the whole routine again:
-<p>
-<pre>
-	.HEADER_CENTER "Endnotes"
-	.ENDNOTES
-	.COLLATE
-	.TITLE         "New Doc Title"
-	.AUTHOR        "Josephine Blough"
-	.HEADER_CENTER "\*[$TITLE]"
-	.START
-</pre>
-
-If need be, you can concatenate the strings, as in the following
-example.
-<p>
-<pre>
-	.HEADER_CENTER "\*[$CHAPTER_STRING] \*[$CHAPTER]"
-</pre>
-
-which, assuming a <strong>.CHAPTER_STRING</strong> of
-&quot;Chapter&quot; and a <strong>.CHAPTER</strong> of
-&quot;2&quot;, would put &quot;Chapter 2&quot; in the header centre
-position.
-<p>
-
-<a name="PAGE_NUMBER_SYMBOL">
-	<h3><u>*Replacing header-left, -CENTER or -right with the page number</u></h3>
-</a>
-<p>
-If you would like to have the current page number to appear 
-header-left, -center, or -right <em>instead</em> of a text
-string, invoke the appropriate macro, above, with the single
-argument <code>#</code> (the &quot;number&quot; or
-&quot;pound&quot; sign).  Do <strong>NOT</strong> use
-double-quotes.  For example,
-<p>
-<pre>

-<strong>_RIGHT</strong>, use the special
-<a href="definitions.html#TERMS_INLINES">inline escape</a>
-<code>\*[PAGE#]</code> in the string argument.
-<p>
-For example, say you have a document that's ten pages long, and
-you want header-right to say "page &lt;whichever&gt; of 10",
-invoke <strong>HEADER_RIGHT</strong> as follows:
-<p>
-<pre>
-	.HEADER_RIGHT "page \*[PAGE#] of 10"
-</pre>
-
-Header-right of page two will read &quot;page 2 of 10&quot;,

-</a>
-
-<a name="INTRO_INLINE_ESCAPES">
-Inline escapes, as described in the
-<a href="definitions.html#TERMS_INLINES">groff terms</a>
-section of this manual, are typesetting commands that appear in
-text
-<a href="definitions.html#TERMS_INPUTLINE">input lines</a>,
-as opposed to macros and other
-<a href="definitions.html#TERMS_CONTROLLINES">control lines</a>
-that must appear on lines by themselves.
-<p>
-Aside from altering type parameters within a line, inlines also
-tell groff about special characters -- em-dashes, bullets,
-<a href="definitions.html#TERMS_FIGURESPACE">figure/digit-width spaces</a>,
-and so on.  It is beyond the scope of this manual to provide a
-complete list of groff's inline functions and special characters.
-I recommend having a look at the
-<a href="intro.html#CANONICAL">canonical reference materials</a>
-should you need more information than is contained herein.
-<p>
-In groff, the escape character is the backslash ( \ ).  Groff interprets
-everything following the backslash as instructions, not literal text,
-until the escape sequence is complete.  Should you need the actual
-backslash character as part of a line of text, simply enter it twice
-( \\ ).  Groff understands that this means "please print a backslash
-character."  (You can also use <strong>\e</strong> to print a literal
-backslash.)
-<p>
-Groff has a number of ways of recognizing what constitutes a complete
-escape sequence.  This is both a boon and a curse; some escape
-sequences have no terminating delimiter and consequently become
-difficult to distinguish from real input text.  Others require
-the use of an opening parenthesis with no corresponding closing
-parenthesis.  Still others need to be enclosed in square brackets.
-<p>
-<strong>Mom</strong> recognizes that certain escapes get used more
-often than others.  For these, she has a consistent input style that
-takes the form \*[...], which makes them stand out well from the text
-of your documents.  These escapes are the ones listed under
-<a href="#INLINES_MOM">Mom's personal inlines</a>.
-<p>
-Despite <strong>mom</strong>'s best intentions, there are still
-a number of typesetting functions that can only be accomplished
-with groff's native inline escapes.  I've listed the ones that
-strike me as essential, but there are many others.  If you want
-to know what they are, please read the
-<a href="intro.html#CANONICAL">canonical reference materials</a>
-pertaining to groff.
-<p>
-<strong>HELPFUL BIT OF INFORMATION:</strong> Inline escapes can be used
-in

-<h2><u>Mom's personal inlines</u></h2>
-
-<a name="INLINE_FONTS_MOM"><h3><u>Changing fonts</u></h3></a>
-
-<p>
-<strong>Mom</strong> provides five escapes for changing fonts
-inline:
-<p>
-<table valign="baseline" cellpadding="10" summary="inlinefonts">
-<tr>
-	<td><strong>\*[ROM]</strong></td>
-	<td>Change font to medium roman</td>
-</tr>
-<tr>
-	<td><strong>\*[IT]</strong></td>
-	<td>Change font to medium italic</td>
-</tr>
-<tr>
-	<td><strong>\*[BD]</strong></td>
-	<td>Change font to bold roman</td>
-</tr>
-<tr>
-	<td><strong>\*[BDI]</strong></td>
-	<td>Change font to bold italic</td>
-</tr>
-<tr>
-	<td><strong>\*[PREV]</strong></td>
-	<td>Revert to previous font</td>
-</tr>
-</table>
-<p>
-These escapes are provided for merely for convenience, legibility,
-and consistency when typesetting with <strong>mom</strong>.  For
-more complete and flexible inline font control, please see
-<a href="#INLINE_FONTS_GROFF">font control with \f</a>.
-
-<p>
-<strong>NOTE:</strong> If you're using the
-<a href="docprocessing.html#DOCPROCESSING">document processing macros</a>,
-inline font changes remain in effect only for the duration of the
-current document element tag.
-<p>
-
-<!---INLINE_SIZE_MOM--->
-
-<hr width="66%" align="left">
-<a name="INLINE_SIZE_MOM"><h3><u>Changing point size</u></h3></a>
-
-<p>
-<strong>Mom</strong> has two inline escapes for changing point
-size:
-<p>
-<pre>
-	\*[SIZE &lt;size&gt;]
-</pre>
-
-and
-<p>
-<pre>
-	\*[S&lt;size&gt;]
-</pre>
-
-where &quot;size&quot; is the new size you want.  You can use
-either; they behave exactly the same way.  For example, to change
-the point size of type inline to 12 points, you could enter either
-<p>
-<pre>
-	\*[SIZE 12]
-</pre>
-
-or
-<p>
-<pre>
-	\*S[12]
-</pre>
-
-The advantage of the first form is that it's easy to remember, and
-follows <strong>mom</strong>'s usual inline syntax.  The advantage
-of the second is that it's more concise.
-<p>
-Notice that in both cases, the new size does not require a
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>;
-<a href="definitions.html#TERMS_PICASPOINTS">points</a>
-is assumed.  However, a unit of measure may be appended to the size
-if that's what you wish.  Fractional sizes are, of course, allowed.
-<p>
-The size given to <strong>\*[SIZE&nbsp;&lt;size&gt;]</strong> or
-<strong>\*S[&lt;size&gt;]</strong> may be expressed in plus or minus
-terms, which can be very useful.  In the following examples, the word
-&quot;mom&quot; will be output 2 points larger than the point size
-of the rest of the line.
-<p>
-<pre>
-	While she isn't perfect, \*S[+2]mom\*S[-2] isn't half bad.
-	While she isn't perfect, \*[SIZE +2]mom\*[SIZE -2] isn't half bad.
-</pre>
-
-<strong>NOTE:</strong> If you're accustomed to groff's usual way
-of handling inline size requests (<kbd>\sN, \s±N, \s(NN, \s±(NN,
-\s[NNN], \s±[NNN]</kbd>), feel free to continue with your old habits.
-<strong>Mom</strong> doesn't care.
-<p>
-
-<!---INLINE_KERNING_MOM--->
-
-<hr width="66%" align="left">
-<a name="INLINE_KERNING_MOM"><h3><u>Pairwise kerning</u></h3></a>
-
-<p>
-Pairwise kerning means moving specific letter pairs closer
-together or further apart (see

-<strong>NOTE:</strong> Whenever you pass <strong>\w'string'</strong>

-<em>do <strong>NOT</strong> add a unit of measure to the \w'string'

-<!---INLINE_LINEDRAWING_GROFF--->

-<hr width="66%" align="left">
-<a name="INLINE_LINEDRAWING_GROFF"><h3><u>Horizontal line drawing function \l</u></h3></a>
-
-<p>
-The <strong>\l'distance'</strong> inline allows you to draw a
-horizontal rule of the specified distance.  You must supply a
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>.
-Therefore, to set a 3-pica rule into a line of text, you'd do
-<p>
-<pre>
-	A line of text with a superfluous \l'3P' 3-pica rule in it.
-</pre>
-
-<strong>\l'3P'</strong> above not only draws the rule, but
-advances 3 picas horizontally as well, just as you'd expect.
-<p>
-For an easy way of drawing rules to the full measure of the current
-line or tab length, see 
-<a href="#INLINE_RULE_MOM">Full measure rules</a>.
-<p>
-The weight (thickness) of rules varies according to the point size
-in effect when you invoke <strong>\l</strong>, but you can't fix
-the weight with any real precision.  A point size of 12 produces
-a tastefully moderate rule weight of between one-half and one
-point (depending on your printer), and is the point size used by
-<strong>mom</strong> for all macros and routines that create rules.
-<p>
-<strong>NOTE:</strong> There are, in addition to <strong>\l</strong>,
-a number of other line-drawing escapes, but frankly, using them for
-typographically precise drawing is a bit like hammering in a nail
-with a screwdriver -- doable, but not recommended.
-<p>
-Groff comes with a number of &quot;preprocessors&quot; designed
-to ease creating rules, boxes, splines, and so on (tbl, pic,
-and friends), but I tend not to use them.  A firm believer
-in the &quot;right tool for the job,&quot; I prefer a vector
-drawing program when I need to combine type with graphic elements
-(say, a complex ruled form).  Inserting the results into a
-document is easy enough with <strong>.PSPIC</strong> (consult

-<p>
-As might be inferred from the above, <strong>mom</strong> is two macro
-packages in one: a set of typesetting macros, and a set of document
-processing macros.  The typesetting macros govern the physical
-aspects of page layout and provide sane, comprehensible control over
-typographic refinements.  The document processing macros let you focus
-on a document's content and logical structure without worrying about
-typesetting or page layout at all.
-<p>
-Because <strong>mom</strong> provides both typesetting and document
-processing macros, it's safe to say she blurs the distinction between
-document processing and document design.  While her basic document style
-comes with pretty spiffy defaults (okay--change &quot;spiffy&quot;
-to &quot;typographically professional&quot;), you can easily control
-how all the various document elements look: titles, page headers and
-footers, page numbering, heads, subheads, footnotes and so on can be
-made to come out exactly the way you want.  And should you need precise
-typographic control over elements in a document that fall outside the
-range of <strong>mom</strong>'s document element tags, you don't have to
-read up on groff
-<a href="definitions.html#TERMS_PRIMITIVES">primitives</a>
-in order to accomplish what you want; the typesetting macros take
-care of that.
-<p>
-
-<a name="INTRO_TYPESETTING">
-	<h2><u>Typesetting with mom</u></h2>
-</a>
-
-<strong>Mom</strong>'s typesetting macros control the basic parameters
-of type: margins, line length, type family, font, point size,
-linespacing, and so on.  In addition, they allow you to move around
-on the page horizontally and vertically, and to set up tabs, indents,
-and columns.  Finally, they let you adjust such typographic details as
-justification style, letter spacing, word spacing, hyphenation, and
-kerning.
-
-<p>
-In terms of typographic control, these macros resemble the
-commands used on dedicated typesetting computers like Compugraphics and
-Linotronics.  Most of them simply give access to groff's typesetting
-primitives in a way that's consistent and easy to use.  A few of
-them (tabs and indents, for example) handle fundamental typesetting
-requirements in ways radically different from groff primitives.
-
-<p>
-With <strong>mom</strong>'s typesetting macros, you can, if you wish,
-create individual output pages that you design from the ground up.
-Provided you have not signalled to <strong>mom</strong> that you
-want document processing (via the
-<a href="docprocessing.html#START">START</a>
-macro; see below), every macro is a literal command that remains in
-effect until you modify it or turn it off.  This means that if you
-want to create flyers, surveys, tabulated forms, curricula vitae and
-so on, you may do so in the good old-fashioned way: one step at a
-time with complete control over every element on the page.
-<p>
-Years of reading various mailing lists dealing with computer
-typesetting (groff, TeX, and friends) have convinced me that no program
-can ever replace the human eye and human input when it comes to high
-quality typesetting.  As of this writing, a thread on the subject of
-&quot;micro typography&quot; in groff has been going on for nearly a
-month.  The reason for the lengthy thread is obvious; words and
-punctuation on the printed page are too variable, too fluid, to be
-rendered flawlessly by any algorithm, no matter how clever.  (For
-whatever it's worth, a similar problem exists with engraving musical
-scores by computer.)
-<p>
-<strong>Mom</strong> does not try to solve the problems posed
-by things like hanging punctuation, left-margin adjustments for
-upper case letters like T and W, and so on.  She merely tries to
-provide tools that allow knowledgeable typesetters to come up with
-solutions to these problems in ways that are easier and more
-intuitive than manipulating groff at the
-<a href="definitions.html#TERMS_PRIMITIVES">primitive</a>
-level.  As a professional typesetter of more than two decades, and a
-writer, I have encountered few situations that cannot be handled by
-<strong>mom</strong>'s typesetting macros.
-<p>
-<strong>Author's note:</strong> One area where groff itself needs
-serious rethinking is in the matter of an algorithm that takes into
-account both word and letter spacing when
-<a href="definitions.html#TERMS_JUST">justifying</a>
-lines.  At present, only word spacing is adjusted, requiring what I
-consider an unnecessary amount of user intervention whenever
-letter spacing is required.
-<p>
-<a name="INTRO_DOCPROCESSING">
-	<h2><u>Document processing with mom</u></h2>
-</a>
-
-<strong>Mom</strong>'s document processing macros let you format
-documents without having to worry about the typographic details.
-In this respect, <strong>mom</strong> is similar to other groff macro
-packages, as well as to html and LaTeX.  Where <strong>mom</strong>
-differs is in the degree of control you have over the look and
-placement of the various elements of a document.  For example, if you
-don't want your heads underlined, or you want them bigger/smaller,
-or you'd prefer them to be in a different font, or you'd rather they
-were flush left instead of centred, you can make the changes easily
-and have them apply to the whole document.  Temporary and one-off
-changes are easy, too.
-<p>
-<strong>Mom</strong> has some nifty features other macro sets
-don't provide.  For example, you can switch between draft-style and
-final-copy output.  If you regularly make submissions to publishers
-and editors who insist on "typewritten, double-spaced," there's a
-special macro--
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE TYPEWRITE</a>
---that changes typeset documents into ones that would make your
-high-school typing teacher proud.  Footnotes, endnotes, tables of
-contents, multiple columns, nested lists, recto/verso printing and
-user designable headers and footers are also part of the fun.
-<p>
-<a name="INTRO_PHILOSOPHY">
-	<h2><u>Mom's philosophy</u></h2>
-</a>
-
-Formatting documents should be easy, from soup to nuts.  Writers need
-to focus on what they're writing, not on how it looks.  From the
-moment you fire up an editor to the moment you add "FINIS"
-to your opus, nothing should interfere with the flow of your words.
-The commands needed to format your work should be easy to remember,
-comprehensible, and stand out well from the text.  There shouldn't
-be too much clutter.  Your documents should be as readable inside a
-text editor as they are on the printed page.
-<p>
-Unfortunately, in computerland, &quot;easy,&quot;
-&quot;comprehensible,&quot; and &quot;readable&quot; often mean
-&quot;you're stuck with what you get.&quot; No document formatting
-system can give you exactly what you want all the time, every time.
-Documents, it seems, always need to be tweaked, either to satisfy a
-typographic whim or to clarify some aspect of their content.
-<p>
-Groff has traditionally solved the problem of formatting vs. tweaking
-by requiring users of the common macro packages (mm, ms, me and their
-offspring) to resort to groff
-<a href="definitions.html#TERMS_PRIMITIVES">primitives</a>
-and
-<a href="definitions.html#TERMS_INLINES">inline escapes</a>
-for their special typesetting needs.  Not to put too fine a point on
-it, groff primitives tend toward the abstruse, and most inline escapes
-are about as readable in-line as an encrypted password.  This does
-not make for happy-camper writers, who either find themselves stuck
-with a document formatting style they don't really like, or are
-forced to learn groff from the ground up--a daunting task, to say
-the least.
-<p>
-<strong>Mom</strong> aims to make creating documents a simple matter,
-but with no corresponding loss of user control.  The document
-processing macros provide an excellent set of defaults, but if
-something is not to your liking, you can change it.  And in combination
-with the typesetting macros, you have all the tools you need to
-massage passages and tweak pages until they look utterly professional.
-<p>
-One rarely hears the word &quot;user interface&quot; in conjunction
-with document processing.  Since the user formatting takes place
-inside a text editor, little thought is given to the look and feel
-of the formatting commands.  <strong>Mom</strong> attempts to rectify
-this by providing users with a consistent, readable &quot;coding&quot;
-style.  Most of the macros (especially in the document processing set)
-have humanly-readable names.  Not only does this speed up learning
-the macros, it makes the sense of what's going on in a document,
-typographically and structurally, easier to decipher.
-<p>
-<strong>Mom</strong> does not try to be all things to all people.
-In contrast to the normal groff philosophy, she does not try to
-produce output that looks good no matter where it's displayed.
-She's designed for printed output, although with
-<a href="#PRINTSTYLE">PRINTSTYLE TYPEWRITE</a>
-she produces acceptable terminal copy.  She makes no attempt to be
-compatible with older versions of troff.
-<p>
-One special feature in <strong>mom</strong>'s design is the attention
-she pays to aligning the bottom margins of every page.  Nothing screams
-&quot;shoddy&quot; in typeset documents louder than bottom margins
-that wander, or, in typesetter jargon, &quot;hang.&quot; There are,
-of course, situations where whitespace at the bottom of a page may
-be desirable (for example, you wouldn't want a head to appear at the
-bottom of the page without some text underneath it), but in all cases
-where hanging bottom margins can be avoided, <strong>mom</strong> does
-avoid them, by clever adjustments to leading (&quot;line spacing&quot;)
-and the spacing between different elements on the page.
-<p>
-<a name="INTRO_DOCUMENTATION">
-	<h2><u>A note on mom's documentation</u></h2>
-</a>
-
-Writing documentation is tough, no doubt about it.  One is never
-quite sure of the user's level of expertise.  Is s/he new to the
-application, new to its underlying protocols and programs, new to
-the operating system, new to computers?  At some point, one has to
-decide who the documentation is for.  Making the wrong decision can
-mean the difference between a program that gets used and a program
-that gets tossed.
-<p>
-<strong>Mom</strong>'s documentation assumes users know their way
-around GNU/Linux.  It further assumes they at least know what groff
-is, even if they don't know much about it.  Lastly, it assumes that
-everyone--groff newbies and experts alike--learns faster from
-a few well-placed examples than from manpage-style reference docs.
-What <strong>mom</strong>'s documentation doesn't assume is that
-you know everything--not about groff, not about typesetting,
-not about document processing.  Even experts have odd lacunae in
-their knowledge base.  Therefore, whenever I suspect that a term
-or procedure will cause head scratching, I offer an explanation.
-And when explanations aren't enough, I offer examples.
-<br>
-
-<a name="CANONICAL"><h3><u>Canonical reference materials</u></h3></a>
-<p>
-The canonical reference materials for groff are
-<strong>cstr54</strong> (a downloadable PostScript copy of which is
-available
-<a href="http://www.kohala.com/start/troff/">here</a>)
-and the <strong>troff</strong> and <strong>groff_diff</strong>
-manpages.  Another excellent source of information (maybe the best)
-is the groff <strong>info</strong> pages, available by typing
-<p>
-<pre>
-	info groff
-</pre>
-
-at the command line (assuming you have <strong>info</strong>
-installed on your system).  And for inputting special characters,
-see <strong>man groff_char.</strong>
-<p>
-I've tried to avoid reiterating the information contained in these
-documents; however, in a few places, this has proved impossible.
-But be forewarned: I have no qualms about sidestepping excruciating
-completeness concerning groff usage; I'm more interested in getting
-<strong>mom</strong> users up and running. <em>Mea culpa.</em>
-<p>
-<strong>Note:</strong> <strong>Mom</strong>'s macro file
-(om.tmac) is heavily commented.  Each macro is preceded by a
-description of its arguments, function and usage, which may
-give you information in addition to what's contained in this
-documentation.
-<p>
-<a name="MACRO_ARGS">
-	<h3><u>How to read macro arguments</u></h3>
-</a>
-
-The concise descriptions of macros in this documentation typically
-look like this:
-<blockquote>
-Macro: <strong>NAME</strong> <nobr>arguments</nobr>
-</blockquote>
-<var>arguments</var> lists the macro's arguments using conventions that
-should be familiar to anyone who has ever read a manpage.  Briefly:
-<p>
-<ol>
-	<li>Macro arguments are separated from each other by spaces.
-	<li>If an argument is surrounded by chevrons
-		(&nbsp;&lt;&nbsp;&gt;&nbsp;), it's a description of the argument,
-		not the argument itself.
-	<li>If an argument begins with or is surrounded by double-quotes, the
-		double quotes MUST be included in the argument.
-	<li>If the user has a choice between several arguments, each of the
-		choices is separated by the pipe character (&nbsp;|&nbsp;),
-		which means &quot;or.&quot;
-	<li>Arguments that are optional are surrounded by square brackets.
-	<li>&lt;off&gt; in an argument list means that any argument
-	    other than those in the argument list turns the macro off.
-</ol>
-
-<a name="TOGGLE_MACRO"><h3><u>Toggle macros</u></h3></a>
-<p>
-Some macros don't require an argument.  They simply start something.
-When you need to turn them off, the same macro with <em>any</em>
-argument will do the trick.  That's right: ANY argument.  This permits
-choosing whatever works for you: OFF, END, QUIT, DONE, Q, X...  Hell,
-it could even be I_LOVE_MOM.
-<p>
-Since these macros toggle things on and off, the argument list
-simply reads
-<blockquote>
-<nobr>toggle</nobr>
-</blockquote>
-<br>
-<hr>
-
-<h3>Example 1: an argument requiring double-quotes</h3>
-<blockquote>
-Macro: <strong>TITLE</strong> <nobr>&quot;&lt;title of document&gt;&quot;</nobr> 
-</blockquote>
-<p>
-The required argument to <strong>TITLE</strong> is the title of your
-document.  Since it's surrounded by double-quotes, you must
-include them in the argument, like this:
-<p>
-<pre>
-	.TITLE "My Pulitzer Novel"
-</pre>
-
-<h3>Example 2: a macro with required and optional arguments</h3>
-<blockquote>
-Macro: <strong>TAB_SET</strong> <nobr>&lt;tab #&gt;  &lt;indent&gt;  &lt;length&gt;  [ L | R | C | J [ QUAD ] ]</nobr> 
-</blockquote>
-<p>
-The first required argument is a number that identifies the tab (say,
-"3").  The second required argument is an indent from the left margin
-(say, 6 picas).  The third required argument is the length of the tab
-(say, 3 picas).  Therefore, at a minimum, when using this macro,
-you would enter:
-<p>
-<pre>
-	.TAB_SET 3 6P 3P
-</pre>
-
-The remaining two arguments are optional.  The first is a single
-letter, either L, R, C or J.  The second, which is itself optional
-after L, R, C or J, is the word QUAD.  Therefore, depending on
-what additional information you wish to pass to the macro,
-you could enter:
-<p>
-<pre>
-	.TAB_SET 3 6P 3P L
-		or
-	.TAB_SET 3 6P 3P L QUAD
-</pre>
-
-<a name="TOGGLE_EXAMPLE"></a>
-<h3>Example 3: a sample toggle macro:</h3>
-<blockquote>
-Macro: <strong>QUOTE</strong> <nobr>toggle</nobr> 
-</blockquote>
-<p>
-<strong>QUOTE</strong> begins a section of quoted text in a document
-and doesn't require an argument.  When the quote's finished,
-you have to tell <strong>mom</strong> it's done.
-<p>
-<pre>
-	.QUOTE
-	So runs my dream, but what am I?
-	An infant crying in the night
-	An infant crying for the light
-	And with no language but a cry.
-	.QUOTE OFF
-</pre>
-
-Alternatively, you could have turned the quote off with END, or
-X, or something else.

-<a name="LETTERS_INTRO">
-	<h2><u>Introduction</u></h2>
-</a>
-
-<strong>Mom</strong>'s simple but effective letter-writing
-macros are a subset of the
-<a href="docprocessing.html#DOCPROCESSING">document processing macros</a>,
-designed to ease the creation of correspondence.
-<p>
-Because the letter macros are a subset of the document
-processing macros, you can use
-<a href="definitions.html#TERMS_CONTROLMACRO">control macros</a>
-to design correspondence to your own specifications.  However,
-<strong>mom</strong> makes no pretence of providing complete design
-flexibility in the matter of letters, which are, after all, simple
-communicative documents whose only real style requirements are that
-they be neat and professional-looking.
-<p>
-<a name="TUTORIAL"><h2><u>Tutorial on writing letters</u></h2></a>
-<p>
-<strong>Mom</strong> letters begin, like all
-<strong>mom</strong>-processed documents, with a
-<a href="docprocessing.html#REFERENCE_MACROS">reference macro</a>
-(in this case,
-<a href="docprocessing.html#AUTHOR">AUTHOR</a>),
-a
-<a href="docprocessing.html#DOCTYPE">DOCTYPE</a>
-(<strong>LETTER</strong>, obviously), the essential
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE</a>
-macro, and
-<a href="docprocessing.html#START">START</a>,
-like this:
-<p>
-<pre>
-	.AUTHOR    "Yannick P. Guique"
-	.DOCTYPE    LETTER
-	.PRINTSTYLE TYPESET
-	.START
-</pre>
-
-<strong>PRINTSTYLE</strong>, above, could also be
-<strong>TYPEWRITE</strong>.  <strong>Mom</strong> has no objection
-to creating letters that look like they were typed on an Underwood
-by a shapely secretary with 1940s gams.
-<p>
-After the <strong>START</strong> macro, you enter headers pertinent to
-your letter: the date, the addressee (in business correspondence,
-typically both name and address), the addresser (that's you; in
-business correspondence, typically both name and address), and a
-greeting (in full, e.g. &quot;Dear Mr. Smith,&quot; or &quot;Dear
-Mr. Smith:&quot;).
-<p>
-The macros for entering the headers are simple (they're not even
-<a href="definitions.html#TERMS_TOGGLE">toggles</a>):
-<p>
-<pre>
-	.DATE
-	.TO
-	.FROM
-	.GREETING
-</pre>
-
-You may enter them in any order you like, except for
-<strong>GREETING</strong>, which must come last.
-<strong>Mom</strong> ignores any headers you omit and spaces the
-letter's opening according to what you do include.  See
-<a href="#LETTERS_DEFAULTS">Default for letters</a>
-to find out how <strong>mom</strong> formats the headers.
-<p>
-(In pre 1.1.7-a releases of <strong>mom</strong>, the order
-of entry was fixed at the above.  This has been changed, although
-if you do follow the above order, <strong>mom</strong> will
-continue to behave exactly as she did in pre 1.1.7-a.)
-<p>
-Once you've filled in what you need to get a letter started, simply
-type the letter, introducing each and every paragraph, including
-the first, with the
-<a href="docelement.html#PP">PP</a>
-macro.
-<p>
-At the end of the letter, should you wish an indented closing
-(&quot;Yours truly,&quot; &quot;Sincerely,&quot; &quot;Hugs and
-kisses&quot;), invoke the macro <strong>CLOSING</strong> on a
-line by itself and follow it with the text of the closing.  
-<strong>N.B.</strong> Don't put your name here; <strong>mom</strong>
-supplies it automatically from <strong>AUTHOR</strong> with
-enough space to leave room for your signature.
-
-<p>
-Assuming our tutorial letter is for business correspondence,
-here's what the complete letter looks like.

-	Dear Mr. Barrières,

-	It has come to my attention that you have been lobbying the

-	.PP
-	I feel it is my duty to inform you that the success of your

-Once you know your way around <strong>mom</strong>, you may find
-this guide preferable to using the Table of Contents.  It lists (I
-hope) all <strong>mom</strong>'s user-space macros.  The links
-point to references found elsewhere in the documentation.
-<p>
-<strong>NOTE:</strong> This guide uses tables extensively.  Better
-make sure you're reading it in a browser that renders them
-sensibly.

-	<h2><u>Introduction to recto/verso</u></h2>
-</a>
-
-Recto/verso printing allows you to set up a <strong>mom</strong>
-document in such a way that it can be printed on both sides of a
-printer sheet and subsequently bound.
-<p>
-With recto/verso, <strong>mom</strong> automatically takes control
-of the following aspects of alternating page layout:
-<br>
-<ul>
-	<li>switching left and right margins (if they're not equal)
-	<li>switching the left and right parts of the default 3-part
-		<a href="definitions.html#TERMS_HEADER">headers</a>
-		or
-		<a href="definitions.html#TERMS_FOOTER">footers</a>
-		(see the
-		<a href="headfootpage.html#DESCRIPTION_GENERAL">General description of headers</a>)
-	<li>switching
-		<a href="headfootpage.html#HDRFTR_RECTOVERSO">HEADER_RECTO</a>
-		and
-		<a href="headfootpage.html#HDRFTR_RECTOVERSO">HEADER_VERSO</a>
-		if user-defined, single string recto/verso headers
-		or footers are used in place of the default 3-part
-		headers or footers
-	<li>switching the page number position (if page numbers are not centred)
-</ul>
-<p>
-It is beyond the scope of this documentation to cover the different
-ways in which you can make your printer print on both sides of a sheet.
-A simple but effective method for those of us with &quot;dumb&quot;
-printers is to open the document (after it's been processed into
-PostScript by groff -- see
-<a href="using.html#USING_INVOKING">How to invoke groff with mom</a>)
-in <strong>gv</strong> (ghostview),
-click the &quot;odd pages&quot; icon, then click &quot;Print
-Marked&quot;.  After printing is complete, rearrange the sheets
-appropriately, put them back in your printer, and have
-<strong>gv</strong> print the &quot;even pages&quot;.  If you prefer to
-work from the command line, check out the man pages for
-<strong>pstops</strong> and <strong>psbook</strong>.  There are other
-programs out there as well to help with two-sided printing.

-Macro: <strong>RECTO_VERSO</strong>
-
-<p>
-If you want <strong>mom</strong> to set up alternating pages for
-recto/verso printing, simply invoke <strong>RECTO_VERSO</strong>
-with no argument.
-<p>
-<strong>NOTE:</strong>
-<br>
-Recto/verso always switches the left and right parts of
-<a href="definitions.html#TERMS_HEADER">headers</a>
-or
-<a href="definitions.html#TERMS_FOOTER">footers</a>
-on odd/even pages.  However, it only switches the left and right
-margins if the margins aren't equal.  Consequently, it is your
-responsibility to set the appropriate differing left and right
-margins with
-<a href="typesetting.html#L_MARGIN">L_MARGIN</a>
-and

-and
-<a href="docprocessing.html#DOC_RIGHT_MARGIN">DOC_RIGHT_MARGIN</a>
-(before or after <strong>START</strong>).
-<p>
-Equally, recto/verso only switches the page number position if page
-numbers aren't centred, which means you have to set the page
-number position with
-<a href="headfootpage.html#PAGENUM_POS">PAGENUM_POS</a>
-(before or after <strong>START</strong>).

-Macro: <strong>SWITCH_HEADERS</strong>
-
-<p>
-<strong>SWITCH_HEADERS</strong> switches the location of the
-header left string (by default, the author) and the header right
-string (by default, the document title).  If you don't like
-<strong>mom</strong>'s default placement of author and title, use
-<strong>SWITCH_HEADERS</strong> to reverse it.
-<p>
-<strong>SWITCH_HEADERS</strong> can also be useful in conjunction
-with
-<a href="#RECTO_VERSO">RECTO_VERSO</a>.
-The assumption of <strong>RECTO_VERSO</strong> is that the first
-page of a document (recto/odd) represents the norm for header-left
-and header-right, meaning that the second (and all subsequent even)
-page(s) of the document exchange header-left and header-right.
-<p>
-If <strong>mom</strong>'s behaviour in this matter is not what
-you want, simply invoke <strong>SWITCH_HEADERS</strong> on the
-first page of your recto/verso document to reverse her default
-treatment of header parts.  The remainder of your document (with

-	<h2><u>Introduction to collating</u></h2>
-</a>
-
-The macro <strong>COLLATE</strong> lets you join documents together.
-Primarily, it's a convenience for printing long documents that
-comprise several chapters, although it could be used for any
-document type (except <strong>LETTER</strong>).
-<p>
-Personally, I prefer to keep chapters in separate files and print
-them out as needed.  However, that means keeping track of the correct
-starting page number for each chapter, a problem circumvented by the
-use of <strong>COLLATE</strong>.
-<p>
-When collating chapters, you need only put <code>.COLLATE</code>
-at the end of a chapter, follow it with any
-<a href="docprocessing.html#REFERENCE_MACROS">reference macros</a>
-needed for the new chapter, e.g.
-<a href="docprocessing.html#CHAPTER">CHAPTER</a>
-or
-<a href="docprocessing.html#CHAPTER_STRING">CHAPTER_STRING</a>
-(have a look at the
-<a href="#CHAPTER_NOTE">Special Note on CHAPTER</a>)
-make any pertinent style changes to the document (unlikely, but
-possible), and re-invoke the
-<a href="docprocessing.html#START">START</a>
-macro.  Your new chapter will begin on a fresh page and behave
-as expected.
-<p>
-<strong>COLLATE</strong> assumes you are collating documents/files
-with similar type-style parameters hence there's no need for
-<strong>PRINTSTYLE</strong> to appear after <strong>COLLATE</strong>,
-although if you're collating documents that were created as separate
-files, chances are the <strong>PRINTSTYLE</strong>'s already there.
-<p>
-<a name="CAUTION"></a>
-<strong><u>Two words of caution:</u></strong>
-<ol>
-	<li>Do not collate documents of differing
-		<strong>PRINTSTYLES</strong> (i.e. don't try to
-		collate a TYPESET document and TYPEWRITE document).
-	<li>Use <strong>DOC_FAMILY</strong> instead of
-		<strong>FAMILY</strong> if, for some reason, you want
-		to change the family of all the document elements after
-		<strong>COLLATE</strong>.  <strong>FAMILY</strong>, by
-		itself, will change the family of paragraph text only.

-	<h2><u>Introduction to bibliographies and references</u></h2>
-</a>
-
-<strong>Mom</strong> provides the ability to automatically format
-and generate bibliography pages, as well as footnote or endnote
-bibliographic references, or references embedded in text.  She
-accomplishes this by working in conjunction with a special
-<strong>groff</strong> program called "refer".
-<p>
-<strong>refer</strong> is a <strong>groff</strong>
-"pre-processor", which is to say that it scans your files looking
-for very specific commands (i.e. lines that begin with a period
-[dot], just like macros and document element tags).  If the
-commands aren't there, <strong>refer</strong> can't do it's job,
-and neither can <strong>mom</strong>.  The scanning is done
-<strong>before</strong> any actual <strong>mom</strong> processing
-occurs.
-<p>
-<strong>refer</strong> is a program that's been around for a long
-time.  It's powerful and has many, many features.  Unfortunately,
-the manpage (<kbd>man refer</kbd>), while complete and accurate, is
-dense and not a good introduction to <strong>refer</strong>.  (It's
-a classic manpage Catch-22: the information it contains is most
-useful only after you already grasp it.)
-<p>
-In order to get <strong>mom</strong> users up and running with
-<strong>refer</strong>, this section of <strong>mom</strong>'s
-documentation focuses exclusively, in a recipe-like manner, on
-what you need to know to use <strong>refer</strong> satisfactorily
-in conjunction with <strong>mom</strong>.  The information and
-instructions are <strong><em><u>not</u></em></strong> to be taken as
-a manual or tutorial on full <strong>refer</strong> usage.  Much has
-been left out, on purpose.
-<p>
-It is tempting to provide two levels of documentation, one for
-users familiar with <strong>refer</strong> and one for newcomers
-to <strong>groff</strong> and <strong>mom</strong>, but such an
-approach may muddy the waters for newcomers. <strong>Mom</strong>'s
-allegiance, first and foremost, is to newcomers.  If you're already
-a <strong>refer</strong> user, the information herein will be useful
-for adapting your current <strong>refer</strong> usage to
-<strong>mom</strong>'s way of doing things.  If you've never used
-<strong>refer</strong>, the information is essential, and, in many
-cases, may be all you need.
-<p>
-(For the benefit of old groff-hands: <strong>refer</strong>
-support in <strong>mom</strong> is heavily based on the
-<strong>refer</strong> module of the ms macros.  The choice
-was deliberate so that those wishing to play around with
-<strong>mom</strong>'s bibliography formatting style would be
-tinkering with the familiar.)
-<p>
-<strong>refer</strong> requires first that you create a
-bibliographic database.  From the information contained in the
-database, <strong>mom</strong> formats and generates bibliographies
-and references in MLA (Modern Language Association) style.  MLA
-style is clean, contemporary and flexible, and is widely used in
-the humanities, where the range of material that has to be
-referenced can run from simple books to live interviews and film.
-<p>
-Once you have created your database, you instruct
-<strong>refer</strong> (and <strong>mom</strong>) to access entries
-in it by supplying keywords from the entries.  Depending on what
-you've instructed <strong>mom</strong> to do, she will put the
-entries--fully and properly formatted with respect to order, punctuation
-and italicization--in footnotes, endnotes, or a full bibliography.
-<p>
-I encourage anyone interested in what MLA style looks like--and, by
-extension, how your bibliographies and references will look after
-<strong>mom</strong> formats them--to check out
-<p>
-<pre>
-	http://www.aresearchguide.com/12biblio.html
-</pre>
-
-or any other website or reference book on MLA style.
-<p>
-<strong>NOTE:</strong> MLA style requires that second and
-subsequent lines of individual references be indented.  <strong>Mom</strong>
-takes care of this for you with a default indent, which
-can be changed with the macro
-<a href="#INDENT_REFS">INDENT_REFS</a>.

-<a name="DB_REF"><h3><u>1. Creating a refer database</u></h3><a>
-<p>
-The first step in using <strong>refer</strong> with
-<strong>mom</strong> is setting up your bibliographic database.
-The database is a file containing separate entries for each
-reference you want to access from your <strong>mom</strong> files.
-The file is <em>not</em> a "mom" file; it is a separate database.
-You may set up individual databases for individual documents, or
-create a large database that contains all the references you'll
-ever need.
-<p>
-Entries ("records") in the database file are separated from each
-other by a single, blank line.  The records themselves are composed
-of single lines ("fields") with no blank lines between them.  Each
-field begins with a percent sign and a single letter (the "field
-identifier") e.g. %A or %T. The letter identifies what part of a
-bibliographic entry the field refers to: Author, Title, Publisher,
-Date, etc.  After the field identifier comes a single space,
-followed by the information appropriate to field.  No punctuation
-should go at the ends of fields; <strong>mom</strong> adds what's
-correct automatically.  Do note, however, that author(s) (%A)
-requires that you enter the author information exactly as you wish
-it to come out (minus the period), including the comma after the
-first author's last name.
-<p>
-Here's a sample database containing two records so you can
-visualize what the above paragraph says:
-<p>
-<pre>
-%A Schweitzer, Albert
-%A C.M. Widor
-%T J.S. Bach
-%l Ernest Newman
-%V Vol 2
-%C London
-%I Adam and Charles Black
-%D 1923
-%O 2 vols
-%K bach vol 2
-
-%A Schaffter, Peter
-%T The Schumann Proof
-%C Toronto
-%I RendezVous Press
-%D 2004
-%K schumann schaffter
-</pre>
-
-The order in which you enter fields doesn't matter.
-<strong>mom</strong> and <strong>refer</strong> will re-arrange
-them in the correct order for you.
-<p>
-The meaning of the letters follows.  There are, with
-<strong>refer</strong>, quite a few--all uppercase--which have, over
-time, come to be "standard". <strong>Mom</strong> respects these.
-However, she adds to the list (mostly the lowercase letters).
-<p>
-<pre>
-	%A Author           -- additional authors may be entered on separate %A
-	                       lines as in first entry of the sample, above; mom 
-	                       and refer will figure out what to do with multiple
-	                       authors according to MLA rules
-	%T Title            -- either the primary title (e.g. of a book), or the
-	                       title of an article (e.g. within a book or
-	                       journal or magazine)
-	%B Book title       -- the title of a book when %T contains the title
-	                       of an article; otherwise, use %T for book
-	                       titles
-	%R Report number    -- for technical reports
-	%J Journal name     -- the name of a journal or magazine when %T
-	                       contains the title of an article
-	%E Editor           -- additional editors may be entered on separate %E
-	                       lines (like authors); mom and refer will figure
-	                       out what to do with them according to MLA rules
-	%e Edition          -- the number of name of a specific edition
-	                       (e.g. Second, 2nd, Collector's, etc.)
-	%V Volume           -- volume number of a journal or series of books
-	%N Journal number   -- journal or magazine number
-	%S Series           -- series name for books or journals that are part of
-	                       a series
-	%C City             -- the city of publication
-	%I Publisher        -- the publisher; %I stands for "Issuer"
-	%D Publication date
-	%P Page number(s)   -- enter page ranges as, e.g., 22-25
-	%G Gov't.
-	   ordering number  -- for government publications
-	%O Other            -- additional information or comments you want
-	                       to appear at the end of the reference
-	%K Keywords         -- any words that will clear up ambiguities
-	                       resulting from database entries that
-	                       contain, say, the same author or the
-	                       same title
-	%d original
-	   publication date -- if different from the date
-	                                   of publication
-	%a additions        -- for books, any additions to the original work,
-					       such as the preface to a new edition or a new
-	                       introduction
-	%t reprint title    -- if different from a work's original title
-	%l translator       -- if the translator is not the editor; if more
-	                        than one translator, this field should contain
-	                        all the names, with appropriate punctuation
-	%r translator
-	   and editor       -- if tr. and ed. are one in the same;
-	%s site name        -- for web sites, the site name
-	%c content
-	   of site          -- for web sites, the content, if unclear
-	                       (i.e. advertisement, cartoon, blog)
-	%o organization     -- for web sites, the organization, group or
-	                       sponsor of the site
-	%a access date      -- for a website, the date you accessed it
-	%u URL              -- for websites, the full URL of the site

-<a name="REF_DISC_HY"></a>
-<strong>Tip:</strong> If you have hyphenation turned on in your
-document (you probably do), <strong>mom</strong> will hyphenate
-your references.  This can be a problem because references
-typically contain several proper names.  Proper names shouldn't be
-hyphenated.  The solution is to prepend to any proper name in the
-database the <strong>groff</strong>
-<a href="definitions.html#TERMS_DISCRETIONARYHYPHEN">discretionary hyphen</a>
-character, <strong>\%</strong>, like this:
-<p>
-<pre>
-	%A Hill, \%Reginald
-</pre>
-
-Alternatively, you can turn hyphenation off entirely in
-references with the macro,
-<a href="#HYPHENATE_REFS">HYPHENATE_REFS</a> <kbd>OFF</kbd>.
-<p>
-
-<a name="RCOMMANDS_REF"><h3><u>2. Required "refer" commands</u></h3><a>
-<p>
-Having set up your database, you now need to put some
-<strong>refer</strong>-specific commands at the top of your
-<strong>mom</strong> file.  You cannot skip this step, nor can you
-"source" these commands with the <strong>groff</strong>
-<a href="definitions.html#TERMS_PRIMITIVES">primitive</a>,
-<strong>.so</strong>.  They <strong><em>must</em></strong>
-appear, exactly as shown, in every file requiring bibliographic
-references.
-<p>
-<strong>refer</strong> commands are introduced with a single
-line containing <kbd>.R1</kbd>, and concluded with a single line
-containing <kbd>.R2</kbd>.  What you put between the <kbd>.R1</kbd>
-and <kbd>.R2</kbd> lines are the commands themselves.  The commands
-should be entered one per line, in lowercase letters, <em><u>with
-no initial period (dot)</u></em>.
-<p>
-Here's an example:
-<p>
-<pre>
-	.R1
-	no-label-in-text
-	no-label-in-reference
-	.R2
-</pre>
-
-There are an awful lot of <strong>refer</strong> commands.  We will
-focus only on those required to get <strong>mom</strong> cooperating
-with <strong>refer</strong>.  If you're interested, study the
-<strong>refer</strong> manpage to discover what other commands are
-available and how to manipulate them.
-<p>
-At a minimum, all <strong>mom</strong> files accessing
-a bibliographic database must contain the following
-<strong>refer</strong> commands, exactly as shown:
-<p>
-<a name="REFER_BLOCK1"></a>
-<pre>
-.R1
-no-label-in-text
-no-label-in-reference
-join-authors ", and " ", " ", and "
-database &lt;full path to the database&gt;
-.R2
-</pre>
-
-The first two commands tell <strong>refer</strong> to let
-<strong>mom</strong> handle everything associated with footnote
-and endnote markers, both in the body of the document, and in the
-footnotes/endnotes themselves.
-<p>
-The third command is required for <strong>mom</strong> to handle
-multiple authors in proper, MLA style.
-<p>
-The last command, <kbd>database</kbd>, assumes you have created
-your own database, and do not otherwise have a system-wide
-"default" database.  "...full path to the database" means the full
-path <em>including</em> the database filename, e.g.
-/home/user/refer/my_database.
-<p> If you're already a <strong>refer</strong> user, feel free to
-enter whatever <strong>refer</strong> commands are necessary to
-access the database(s) you want.
-<p>
-With the above <strong>refer</strong> block, you can embed
-references directly into the text of your document, or have them
-output as footnotes or endnotes.  If you want to "collect"
-references for later output on a bibliography page, the block must
-read:
-<p>
-<pre>
-.R1
-no-label-in-text
-no-label-in-reference
-join-authors ", and " ", " ", and "
-database &lt;full path to the database&gt;
-sort
-accumulate
-.R2
-</pre>
-
-<a name="ACCESSING_REF"><h3><u>3. Accessing references</u></h3><a>
-<p>
-References are accessed by putting keywords, all on one line,
-between the <strong>refer</strong> commands <strong>.[</strong> and
-<strong>.]</strong>.  Both of these commands must appear on separate
-lines, by themselves, like this:
-<p>
-<pre>
-	.[
-	keyword(s)
-	.]
-</pre>
-
-Keywords are any word, or set of words, that identify a database
-record (i.e. a reference) unambiguously. (<strong>refer</strong>
-doesn't like ambiguity.)
-<p>
-If, for example, you want to reference a book by Ray Bradbury,
-and the database contains only one book by Bradbury, a suitable
-keyword would be "Bradbury".  If your database contains several
-books by Bradbury, say, <em>Fahrenheit 451</em> and <em>The Martian
-Chronicles</em>, you could reference them with the keywords, "451"
-and "Martian".  If, in addition to the two books by Bradbury, you
-also had one whose title was <em>The Martian Mission</em>, suitable
-keywords to reference <em>The Martian Chronicles</em> might be:
-<p>
-<pre>
-	.[                or    .[                   or  .[
-	Bradbury Martian        Bradbury Chronicles      Martian Chronicles
-	.]                      .]                       .]
-</pre>
-
-The database field identifier, %K, lets you create special keywords
-for references.  This can be very handy if you need both a "short"
-and a "long" reference to the same work.  The short reference might
-be used in footnotes; the long one in a bibliography.  Consider the
-following:
-<p>
-<pre>
-	%A Isherwood, Christopher      %A Isherwood
-	%T Mr. Norris Changes Trains   %T Mr. Norris Changes Trains
-	%d 1935                        %K Nor short
-	%t The Last of Mr. \%Norris
-	%a Intro. Tom Crawford
-	%C New York
-	%I New Directions
-	%D 1945
-	%K Norris
-
-</pre>
-
-To access the shorter reference, you'd do
-<p>
-<pre>
-	.[
-	Nor short

-</pre>
-
-To access the longer one, you'd do
-<pre>

-<a name="WHERE_REF"><h3><u>4. Telling mom where to put references</u></h3><a>
-<p>
-<strong>Mom</strong> provides several mechanisms for outputting
-references where you want.
-<p>
-<h3>Embedding references in the document body</h3>
-<p>
-References may be embedded in the document body, surrounded by
-parentheses, square brackets, or braces.  Use whichever you prefer,
-following the recipes below.
-<p>
-<pre>
-	Parentheses    Square brackets    Braces
-	-----------    ---------------    ------
-
-	.REF(          .REF[              .REF{
-	.[             .[                 .[
-	keyword(s)     keyword(s)         keyword(s)
-	.]             .]                 .]
-	.REF)          .REF]              .REF}
-</pre>
-
-<h3>Footnote or endnote references</h3>
-<p>
-Most times, you'll probably want references in either footnotes or
-endnotes.  <strong>Mom</strong> provides a simple mechanism whereby
-you can choose which, or even switch back and forth.  The primary
-tag is
-<a href="#REF">REF</a>, which is used like this:
-<p>
-<pre>
-	.REF
-	.[
-	keyword(s)
-	.]
-	.REF
-</pre>
-
-<strong>REF</strong> collects references and outputs them
-where you say with the macros,
-<a href="#FOOTNOTE_REFS">FOOTNOTE_REFS</a>
-or
-<a href="#ENDNOTE_REFS">ENDNOTE_REFS</a>.
-Neither
-<strong>FOOTNOTE_REFS</strong> nor <strong>ENDNOTE_REFS</strong>
-requires an argument.  All they do is tell <strong>REF</strong>,
-whenever it's invoked, where to put the references.
-<p>
-A recipe for footnote references looks like this:
-<pre>
-	.FOOTNOTE_REFS
-	.REF
-	.[
-	keyword(s)
-	.]
-	.REF
-</pre>
-
-When <strong>FOOTNOTE_REFS</strong> are enabled, <strong>REF</strong>
-behaves identically to
-<a href="docelement.html#FOOTNOTE">FOOTNOTE</a>,
-so please read the
-<a href="docelement.html#FOOTNOTE_NOTE">HYPER IMPORTANT NOTE</a>
-found in the document entry for <strong>FOOTNOTE</strong>.
-<p>
-The reference between the first and second <strong>REF</strong>
-will be treated as a footnote, as will all subsequent
-<strong>REF</strong> pairs unless you invoke the macro,
-<strong>ENDNOTE_REFS</strong>.
-<p>
-A recipe for endnote references looks like this:
-<pre>
-	.ENDNOTE_REFS
-	.REF
-	.[
-	keyword(s)
-	.]
-	.REF
-</pre>
-
-The reference between the first and second <strong>REF</strong>
-will be treated as an endnote, as will all subsequent
-<strong>REF</strong> pairs unless you invoke the macro,
-<strong>FOOTNOTE_REFS</strong>.
-<p>
-When <strong>ENDNOTE_REFS</strong> are enabled, <strong>REF</strong>
-behaves identically to
-<a href="docelement.html#FOOTNOTE">ENDNOTE</a>,
-so please read the
-<a href="docelement.html#ENDNOTE_NOTE">HYPER IMPORTANT NOTE</a>
-found in the document entry for <strong>ENDNOTE</strong>.
-<p>
-The innate flexibility of this scheme allows you to have both
-footnote references and endnote references in the same document.
-This would be desirable if, say, you wanted "short" references in
-footnotes, and complete references in endnotes.
-<p>
-
-<a name="COLLECTED_REF"><h3>Collected references</h3></a>
-<p>
-Sometimes, you may want to put references in input text near
-sections of text to which they pertain, but not actually want
-them output until later (typically, on a bibliography page).
-<strong>REF</strong> is used for this, too, but you have to make
-sure your <strong>refer</strong> commands block is set up properly.
-The recipe for this is:
-<p>
-<a name="REFER_BLOCK2"></a>
-<pre>
-.R1
-no-label-in-text
-no-label-in-reference
-join-authors ", and " ", " ", and "
-database &lt;full path to the database&gt;
-sort
-accumulate
-.R2
-</pre>
-
-After this set up, and provided you don't issue a
-<strong>FOOTNOTE_REFS</strong> or <strong>ENDNOTE_REFS</strong>
-command, all reference between <strong>REF</strong> pairs will be
-collected for later output.
-<p>
-As a precaution, <strong>mom</strong> will issue a message the
-first time you call <strong>.REF</strong> if neither
-<strong>FOOTNOTE_REFS</strong> nor <strong>ENDNOTE_REFS</strong> is
-in effect.  If collected references are what you want, and you have
-set up your <strong>.R1 - .R2</strong> block as above, you may
-safely ignore the message.
-<p>
-<strong>LIMITATION:</strong> You cannot combine "collected"
-references (plain <strong>REF</strong>) with <strong>REF</strong>s
-that are instructed to go into footnotes (with
-<strong>FOOTNOTE_REFS</strong>) or endnotes (with
-<strong>ENDNOTE_REFS</strong>).  This is a limitation imposed by
-<strong>refer</strong>, not <strong>mom</strong>.
-
-<a name="BIBLIO_REF"><h3><u>5. Creating bibliography pages</u></h3><a>
-<p>
-Bibliography pages are separate pages, like endnotes, on which
-complete bibliographies are output.  And, like endnotes pages, just
-about every element on them can be designed to your specifications
-with control macros.  (See
-<a href="#BIBLIO_CONTROL_MACROS">Control macros for bibliographies</a>.)
-A bibliography page that uses <strong>mom</strong>'s defaults
-begins with the macro,
-<a href="BIBLIOGRAPHY">BIBLIOGRAPHY</a>,
-like this:
-<p>
-<pre>
-	.BIBLIOGRAPHY
-</pre>
-
-<p>
-Following <strong>BIBLIOGRAPHY</strong>, you have three choices of
-how to proceed.
-<p>
-If you have elected to have references collected from within the
-body of a document (see above,
-<a href="#COLLECTED_REF">Collected references</a>, 
-for instructions), which assumes you have a <strong>refer</strong>
-command block like the one
-<a href="#REFER_BLOCK2">here</a>
-at the top of your document, you need only do
-<p>
-<pre>
-	.BIBLIOGRAPHY
-	.[
-	$LIST$
-	.]
-</pre>
-
-If you want to create the bibliography by hand (which may be the
-case if you've used footnote and/or endnote references throughout
-your document), follow this recipe, which assumes you already have a
-<strong>refer</strong> block like the one
-<a href="#REFER_BLOCK1">here</a>
-at the top of your document:
-<p>
-<pre>
-	.BIBLIOGRAPHY
-	.R1
-	sort
-	accumulate
-	.R2
-	.[          -+
-	keyword(s)   |
-	.]           | "keyword(s)" are keywords identifying the
-	.[           | particular bibliographic reference you want
-	keyword(s)   | from your database.  Order doesn't matter here;
-	.]           | the refer command, sort, takes care of that.
-	.[           |
-	keyword(s)   |
-	.]          -+
-	.[
-	$LIST$
-	.]
-</pre>
-
-Your final choice is to output your whole database.  Again,
-assuming you have a <strong>refer</strong> block like the one
-<a href="#REFER_BLOCK1">here</a> at the top of your file, you need
-only do:
-<p>
-<pre>
-	.BIBLIOGRAPHY
-	.R1
-	bibliography &lt;full path to database&gt;
-	.R2
-</pre>
-
-If you haven't put a <strong>refer</strong> block in
-your file already, you can put the whole thing after
-<strong>BIBLIOGRAPHY</strong>, like this:
-<p>
-<pre>
-	.BIBLIOGRAPHY
-	.R1
-	no-label-in-text                       -+
-	no-label-in-reference                   | These are actually optional
-	database &lt;full path to the database&gt;   -+ 
-	join-authors ", and " ", " ", and "
-	bibliography &lt;full path to database&gt;
-	.R2
-</pre>
-
-Whichever option you choose, <strong>mom</strong> will output a
-full bibliography page, complete with a title (BIBLIOGRAPHY by
-default, but that can be changed).

-<a name="REF"><h3><u>Marking off references for footnotes, endnotes, or collection</u></h3></a>
-<p>
-
-Tag: <strong>REF</strong>
-<p>
-The macro, <strong>REF</strong>, tells <strong>mom</strong> that
-what follows is <strong>refer</strong>-specific, a
-keyword-identified reference from a
-<strong>refer</strong> database.  Depending on whether you've
-issued a
-<a href="#FOOTNOTE_REFS">FOOTNOTE_REFS</a>
-or
-<a href="#ENDNOTE_REFS">ENDNOTE_REFS</a>
-instruction, <strong>REF</strong> also tells <strong>mom</strong>
-where to place the reference.  If <strong>FOOTNOTE_REFS</strong>,
-the reference will be formatted and placed in a footnote.  If
-<strong>ENDNOTE_REFS</strong>, the reference will be collected for
-output as an endnote.  If you have issued neither instruction, the
-reference will be collected for later output, most likely on a
-<a href="#BIBLIOGRAPHY">bibliography page</a>.
-<p>
-Before you use <strong>REF</strong>, you must create a
-<strong>refer</strong> block containing <strong>refer</strong>
-commands (see
-<a href="#RCOMMANDS_REF">Required refer commands</a>
-in the tutorial, above).
-<p>
-<strong>REF</strong> usage always looks like this:
-<p>
-<pre>
-	.REF
-	.[
-	keyword(s)
-	.]
-	.REF
-</pre>
-
-Notice that <strong>REF</strong> "brackets" the
-<strong>refer</strong> call, and never takes an argument.
-<p>
-What <strong>REF</strong> really is is a convenience.  One could,
-for example, put a reference in a footnote by doing
-<p>
-<pre>
-	.FOOTNOTE
-	.[
-	keyword(s)
-	.]
-	.FOOTNOTE OFF
-</pre>
-
-However, if you have a lot of references going into footnotes (or
-endnotes), it's much shorter to type <kbd>.REF/.REF</kbd> than
-<kbd>.FOOTNOTE/.FOOTNOTE OFF</kbd>.  It also helps you
-distinguish--visually, in your input file--between footnotes (or
-endnotes) which are references, and footnotes (or endnotes) which
-are explanatory, or expand on the text.
-<p>
-<strong>Additional arguments:</strong> If you're using
-<strong>REF</strong> to put references in footnotes and your
-footnotes need to be indented, you may (indeed, should) pass
-<strong>REF</strong> the same arguments used to indent footnotes.
-See
-<a href="docelement.html#FOOTNOTE">FOOTNOTE</a>.
-<p>
-<strong>Note:</strong>
-When <strong>REF</strong> is used with
-<a href="#FOOTNOTE_REFS">FOOTNOTE_REFS</a>,
-it behaves identically to
-<a href="docelement.html#FOOTNOTE">FOOTNOTE</a>,

-Invoking it with any other argument (<strong>OFF</strong>,
-<strong>NO</strong>, <strong>X</strong>, etc.) will disable

-<p>
-<nobr>Macro: <strong>BIBLIOGRAPHY_PT_SIZE</strong> &lt;base type size of bibliography&gt;</nobr>
-
-<p>
-Unlike most other control macros that deal with size of document
-elements, <strong>BIBLIOGRAPHY_PT_SIZE</strong> takes as its argument an
-absolute value, relative to nothing.  Therefore, the argument represents
-the size of bibliography type in
-<a href="definitions.html#TERMS_PICASPOINTS">points</a>,
-unless you append an alternative
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>.
-For example,
-<p>
-<pre>
-	.BIBLIOGRAPHY_PT_SIZE 12
-</pre>
-
-sets the base point size of type on the bibliography page to 12
-points, whereas
-<p>
-<pre>
-	.BIBLIOGRAPHY_PT_SIZE .6i
-</pre>
-
-sets the base point size of type on the bibliography page to 1/6 of an
-inch.
-<p>
-The type size set with <strong>BIBLIOGRAPHY_PT_SIZE</strong> is the size of
-type used for the text of the bibliographies, and forms the basis from which
-the point size of other bibliography page elements is calculated.
-<p>
-The default for
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE TYPESET</a>
-is 12.5 points (the same default size used in the body of the document).

-<em>*Does not require a <a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>; points is assumed</em>
-
-<p>
-Unlike most other control macros that deal with leading of document
-elements, <strong>BIBLIOGRAPHY_LEAD</strong> takes as its argument an
-absolute value, relative to nothing.  Therefore, the argument represents
-the
-<a href="definitions.html#TERMS_LEADING">leading</a>
-of endnotes in
-<a href="definitions.html#TERMS_PICASPOINTS">points</a>
-unless you append an alternative
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>.
-For example,
-<p>
-<pre>
-	.BIBLIOGRAPHY_LEAD 14
-</pre>
-
-sets the base leading of type on the bibliography page to 14
-points, whereas
-<p>
-<pre>
-	.BIBLIOGRAPHY_LEAD .5i
-</pre>
-
-sets the base leading of type on the bibliography page to 1/2 inch.
-<p>
-If you want the leading of bibliographies adjusted to fill the page,
-pass <strong>BIBLIOGRAPHY_LEAD</strong> the optional argument
-<strong>ADJUST</strong>.  (See
-<a href="docprocessing.html#DOC_LEAD_ADJUST">DOC_LEAD_ADJUST</a>
-for an explanation of leading adjustment.)
-<p>
-The default for
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE TYPESET</a>
-is 14 points, adjusted.
-<p>
-<strong>NOTE:</strong> Even if you give <strong>mom</strong> a
-<strong>DOC_LEAD_ADJUST OFF</strong> command, she will still, by
-default, adjust bibliography leading.  You MUST enter
-<strong>BIBLIOGRAPHY_LEAD &lt;lead&gt;</strong> with no
-<strong>ADJUST</strong> argument to disable this default behaviour.

-double-spacing, bibliographies are double-spaced.  If your document
-is single-spaced, bibliographies are single-spaced.
-<p>
-If, for some reason, you'd prefer that bibliographies be single-spaced

-By default, <strong>mom</strong> inserts 1 linespaces between

-add a different amount of space, instruct her to do so with the
-macro, <strong>BIBLIOGRAPHY_SPACING</strong>.  Say, for example,
-you'd prefer only 1/2 linespace.  That would be done with
-<p>
-<pre>
-	.BIBLIOGRAPHY_SPACING .5v
-</pre>
-
-As with endnotes pages, owing to the space inserted between bibliography
-entries, bibliography pages may have hanging bottom margins.
-Unlike endnotes pages, <strong>mom</strong> is sad to report that
-there's nothing you can do about this, except a) pray things work

-<strong>mom</strong> sets the bibliographies in columns, too.  However,
-if your document is set in columns and you'd like the bibliographies not
-to be, just invoke <strong>BIBLIOGRAPHY_NO_COLUMNS</strong> with no

-of your document.
-<p>
-If you output bibliographies at the end of each document in a

-Use this macro with caution.  If all bibliographies for several

-<p>
-If you set <strong>BIBLIOGRAPHY_FIRST_PAGENUMBER</strong> in collated

-+++ALIASES+++
-
-Please note:
-
-Prior to version 1.1.9, all macros that included the word COLOR had
-aliases that used COLOUR instead.  This convenience has now been
-removed, in an effort to reduce the size of the om.tmac file.
-
-Furthermore, if you want the convenience, you'll have to edit the
-om.tmac file.  Simply aliasing, say, HEAD_COLOR as HEAD_COLOUR will
-not work, owing to significant changes in the handling of
-docelement control macros that end in _COLOR.

-</a>
-
-During document processing, most of the
-<a href="typesetting.html#MACROS_TYPESETTING">typesetting macros</a>
-affect type in the document globally.  For example, if you turn kerning
-off, pairwise kerning is disabled not only in paragraphs, but
-also in headers, footers, quotes, and so on.
-<p>
-Typesetting macros that alter margins and line lengths affect
-<a href="definitions.html#TERMS_RUNNING">running text</a>
-globally (or at least try to), but leave headers/footers and footnotes
-alone.  (To indent footnotes, see the full explanation of the
-<a href="docelement.html#FOOTNOTE">FOOTNOTE</a>
-macro.)
-<p>
-<strong>Mom</strong>'s tabs
-(both
-<a href="typesetting.html#TYPESETTING_TABS">typesetting tabs</a>
-and
-<a href="typesetting.html#STRING_TABS">string tabs</a>)
-behave as expected in running text during document processing.  Tab
-structures that do not exceed the line length of running text are
-preserved sensibly from page to page, and, if
-<a href="docprocessing.html#COLUMNS">COLUMNS</a>
-are enabled, from column to column.
-<p>
-Some typesetting macros, however, when used during document
-processing, behave in special ways.  These are the macros that deal
-with the basic parameters of type style: horizontal and vertical
-margins, line length,
-<a href="definitions.html#TERMS_FAMILY">family</a>,
-<a href="definitions.html#TERMS_FONT">font</a>,
-<a href="definitions.html#TERMS_PS">point size</a>,
-<a href="definitions.html#TERMS_LEADING">leading</a>,
-and
-<a href="definitions.html#TERMS_QUAD">quad</a>.
-
-<p>
-<strong>Mom</strong> assumes that any changes to these parameters
-stem from a temporary need to set type in a style different from that
-provided by <strong>mom</strong>'s
-<a href="docelement.html#INDEX_DOCELEMENT">document element tags</a>.
-In other words, you need to do a bit of creative typesetting in the
-middle of a document.
-<p>
-The following lists those typesetting macros whose behaviour during
-document processing requires some explanation.
-(Please refer to
-<a href="#TB_MARGINS">Top and bottom margins in document processing</a>
-for information on how <strong>mom</strong> interprets
-<a href="typesetting.html#T_MARGIN">T_MARGIN</a>
-and
-<a href="typesetting.html#B_MARGIN">B_MARGIN</a>
-in document processing.  Additionally, see
-<a href="#ADD_SPACE">ADD_SPACE</a>
-if you encounter the problem of trying to get <strong>mom</strong>
-to put space at the tops of pages after the first.)

-<pre>
-MACRO           EFFECT DURING DOCUMENT PROCESSING
------           ---------------------------------
-
-L_MARGIN        *The left margin of all running text
-                 assumes the new value.
-
-                *The line length remains unaltered.
-
-                *The header and footer left margin
-                 remain at the current document default.
-
-                (You won't use this often by itself.  Most
-                 likely, you'll use it in combination with
-                 R_MARGIN or LL.)
-
-R_MARGIN        *The right margin of all running text
-                 assumes the new value.  In other words,
-                 the line length is altered.
-
-                *The header and footer right margin
-                 remain at the current document default.
-
-LL              *The line length of all running text
-                 is set to the new value.
-
-                *The header and footer line length remain
-                 at the current document default.
-
-FAMILY          *Changes family for the duration of the
-                 current tag only.  As soon as another document
-                 element tag is invoked, the family reverts to
-                 the current default for the new tag.
-
-FT              *Changes font for the duration of the
-                 current tag only.  As soon as another document
-                 element tag is entered, the font reverts
-                 to the current default for the new tag.
-
-                 N.B. -- \*[SLANT] and \*[BOLDER] affect
-                 paragraph text, and remain in effect for all
-                 paragraphs until turned off.  If you want to
-                 use them in a macro that takes a string
-                 argument, include the escape in the string.
-                 \*[COND] and \*[EXT] behave similarly.
-
-PT_SIZE         *Changes point size for the duration of the
-                 current tag only.  As soon as another document
-                 element tag is entered, the point size reverts
-                 to the current document default for the new
-                 tag.
-
-LS              *Changes line space for the duration of the
-                 current tag only.  As soon as another document
-                 element tag is entered, the line space reverts to
-                 the current document default for the new
-                 tag.
-
-                 Using LS to temporarily change leading within a
-                 document will almost certainly result in a bottom
-                 margin that doesn't align with the bottom margin
-                 of subsequent pages.  You'll need to use the SHIM
-                 macro to get mom back on track when you're ready
-                 to return to the document's default leading.
-
-QUAD            *Changes quad for the duration of the
-                 current tag only.  As soon as another document
-                 element tag is entered, the quad reverts to
-                 the current document default for the new
-                 tag.
-
-                 N.B. -- Line-for-line quadding macros
-                 (LEFT, CENTER, RIGHT) are also temporary,
-                 overridden by the QUAD value of any subsequent
-                 document element tag.

-<a name="TB_MARGINS">
-	<h2><u>Top and bottom margins in document processing</u></h2>
-</a>
-
-Normally, <strong>mom</strong> establishes the top and bottom margins
-of
-<a href="definitions.html#TERMS_RUNNING">running text</a>
-in documents from the values of <strong>HEADER_MARGIN +
-HEADER_GAP</strong> and <strong>FOOTER_MARGIN + FOOTER_GAP</strong>
-respectively.  However, if you invoke
-<a href="typesetting.html#T_MARGIN">T_MARGIN</a>
-or
-<a href="typesetting.html#B_MARGIN">B_MARGIN</a>
-either before or after
-<a href="docelement.html#START">START</a>,
-they set the top and bottom margins of running text irrespective
-of <strong>HEADER_GAP</strong> and <strong>FOOTER_GAP</strong>.
-<p>
-Put another way, in document processing, <strong>T_MARGIN</strong>
-and <strong>B_MARGIN</strong> set the top and bottom margins of
-running text, but have no effect on the placement of
-<a href="definitions.html#TERMS_HEADER">headers</a>,
-<a href="definitions.html#TERMS_FOOTER">footers</a>,
-or page numbers.
-
-<a name="ADD_SPACE">
-	<h2><u>ADD_SPACE</u></h2>
-</a>
-
-<p>
-Occasionally, you may want to insert space before the start of
-<a href="definitions.html#TERMS_RUNNING">running text</a>
-on pages after the first.
-<p>
-You might have tried using
-<a href="typesetting.html#ALD">ALD</a>
-or
-<a href="typesetting.html#SPACE">SPACE</a>
-and found it did nothing.  This is because <strong>mom</strong>
-normally inhibits any extra space before the start of running text
-on pages after the first.
-<p>
-If you need the space, you must use the macro,
-<strong>ADD_SPACE</strong>, in conjuction with
-<a href="typesetting.html#NEWPAGE">NEWPAGE</a>.
-<strong>ADD_SPACE</strong> takes as its single argument the
-distance you want <strong>mom</strong> to advance from the normal
-baseline position at the top of the page.  A
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-is required.
-
-<p>
-For example, say you wanted to insert 2 inches of space before the
-start of running text on a page other than the first.  You'd
-accomplish it with
-
-<p>
-<pre>
-	.NEWPAGE
-	.ADD_SPACE 2i
-</pre>
-
-which would terminate your current page, break to a new page,
-print the header (assuming headers are on) and insert 2 inches of
-space before the start of running text.
-<p>
-Since adding space in this way is almost sure to disrupt
-<strong>mom</strong>'s ability to guarantee perfectly flush bottom
-margins, I highly recommend using the
-<a href="docprocessing.html#SHIM">SHIM</a>
-macro immediately after <strong>ADD_SPACE</strong>.

-<h2><a name="INTRO_MACROS_TYPESETTING"><u>Introduction to the typesetting macros</u></a></h2>
-
-<strong>Mom</strong>'s typesetting macros provide access to
-groff's typesetting capabilities.  Aside from controlling basic
-type parameters (family, font, line length, point size, leading),
-<strong>mom</strong>'s macros fine-tune wordspacing, letterspacing,
-kerning, hyphenation, and so on.  In addition, <strong>mom</strong>
-has true typesetting tabs, string tabs, multiple indent styles,
-line padding, and a batch of other goodies.
-<p>
-In some cases, <strong>mom</strong>'s typesetting macros merely imitate
-groff primitives.  In others, they approach typesetting concerns in
-conceptually new ways (for groff, at least).  This should present no
-problem for newcomers to groff who are learning <strong>mom</strong>.
-Old groff hands should be careful.  Just because it looks like a
-duck and walks like a duck does not, in this instance, mean that it
-is a duck.  When using <strong>mom</strong>, stay away from groff
-primitives if <strong>mom</strong> provides a macro that accomplishes
-the same thing.
-<p>
-<strong>Mom</strong>'s typesetting macros can be used as a standalone
-package, independent of the
-<a href="docprocessing.html#DOCPROCESSING">document processing macros</a>.
-With them, you can typeset on-the-fly.  Book covers, your best
-friend's résumé, a poster for a lost dog--none of these requires
-structured document processing (page headers, paragraphs, heads,
-footnotes, etc).  What they do demand is precise control over every

-<br>
-<em>*Requires a <a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a></em>
-
-<p>
-<strong>R_MARGIN</strong> establishes the amount of space you
-want between the end of typeset lines and the right hand edge
-of the printer sheet.  In other words, it sets the line length.
-<strong>R_MARGIN</strong> requires a unit of measure.  Decimal
-fractions are allowed.
-<p>
-The <a href="#LINELENGTH">line length macro</a> (<strong>LL</strong>) can
-be used in place of <strong>R_MARGIN</strong>.  In either case, the
-last one invoked sets the line length.  The choice of which to use is
-up to you.  In some instances, you may find it easier to think of a
-section of type as having a right margin.  In others, giving a line
-length may make more sense.
-<p>
-For example, if you're setting a page of type you know should have
-6-pica margins left and right, it makes sense to enter a left and
-right margin, like this:
-<p>
-<pre>
-	.L_MARGIN 6P
-	.R_MARGIN 6P
-</pre>
-
-That way, you don't have to worry about calculating the line
-length.  On the other hand, if you know the line length for a
-patch of type should be 17 picas and 3 points, entering the line
-length with <strong>LL</strong> is much easier than calculating the
-right margin.
-<p>
-<pre>
-	.LL 17P+3p

-
-If you use the macros
-<a href="#PAGE">PAGE</a>,
-<a href="#PAGEWIDTH">PAGEWIDTH</a>
-or
-<a href="#PAPER">PAPER</a>
-without invoking <strong>R_MARGIN</strong> afterwards,
-<strong>mom</strong> automatically sets <strong>R_MARGIN</strong>
-to 1 inch.  If you set a line length after these macros (with
-<a href="#LINELENGTH">LL</a>),
-the line length calculated by <strong>R_MARGIN</strong> is, of course,
-overridden.
-<p>
-<strong>IMPORTANT: R_MARGIN</strong>, if used, MUST come after
-<a href="#PAPER">PAPER</a>,
-<a href="#PAGEWIDTH">PAGEWIDTH</a>,
-<a href="#L_MARGIN">L_MARGIN</a>
-and/or
-<a href="#PAGE">PAGE</a>
-(if a right margin isn't given to <strong>PAGE</strong>).
-The reason is that <strong>R_MARGIN</strong> calculates line
-length from the overall page dimensions and the left margin.
-Obviously, it can't make the calculation if it doesn't know the page
-width and the left margin.

-
-<p>
-<strong>T_MARGIN</strong> establishes the distance from the top of

-margin of 2-1/2 centimetres, you'd enter
-<p>
-<pre>
-	.T_MARGIN 2.5c
-</pre>
-
-<strong>T_MARGIN</strong> calculates the vertical position of the

-<p>
-<pre>
-	.T_MARGIN 1.5i
-</pre>
-
-puts the baseline of the first line of type 1-1/2 inches beneath
-the top of the page.
-<p>
-<strong>IMPORTANT:</strong> <strong>T_MARGIN</strong> does two
-things: it establishes the top margin for pages that come after

-<p>
-<pre>
-	.B_MARGIN .75i
-</pre>
-
-Obviously, if you haven't spaced the type on your pages so that
-the last lines fall perfectly at the bottom margin, the margin will
-vary from page to page.  Usually, but not always, the last line of
-type that fits on a page <em>before</em> the bottom margin causes

-<p>
-Occasionally, owing to a peculiarity in <strong>groff</strong>,

-<em>*All arguments require a <a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a></em>

-<p>
-<strong>PAGE</strong> lets you establish paper dimensions and page

-The rest are optional, <strong>but they must appear in order and you can't
-skip over any.</strong>  <nobr>&lt;lm&gt;, &lt;rm&gt;, &lt;tm&gt;</nobr>
-and <nobr>&lt;bm&gt; refer to the left, right, top and bottom</nobr>
-margins respectively.
-<p>
-Assuming your page dimensions are 11 inches by 17 inches, and that's
-all you want to set, enter
-<p>
-<pre>
-	.PAGE 11i 17i
-</pre>
-
-If you want to set the left margin as well, say, at 1 inch,
-<strong>PAGE</strong> would look like this:
-<p>
-<pre>
-	.PAGE 11i 17i 1i
-</pre>
-
-Now suppose you also want to set the top margin, say, at 1-1/2
-inches.  <nobr>&lt;tm&gt; comes after <nobr>&lt;rm&gt;</nobr></nobr>
-in the optional arguments, but you can't skip over any arguments,
-therefore to set the top margin, you must also give a right margin.
-The <strong>PAGE</strong> macro would look like this:
-<p>
-<pre>
-        .PAGE 11i 17i 1i 1i 1.5i
-                         |   |
-        required right___|   |___top margin
-                margin
-</pre>
-
-Clearly, <strong>PAGE</strong> is best used when you want a convenient
-way to tell <strong>mom</strong> just the dimensions of your printer
-sheet (width and length), or when you want to tell her everything
-about the page (dimensions and all the margins), for example
-<p>
-<pre>
-	.PAGE 8.5i 11i 45p 45p 45p 45p
-</pre>
-
-This sets up an 8-1/2 by 11 inch page with margins of 45 points
-(5/8-inch) all around.
-<p>
-<strong>NOTE:</strong> Only use <strong>PAGE</strong> at the
-start of a document, before entering any text.  And remember,
-when you're using the
-<a href="docprocessing.html#DOCPROCESSING">document processing macros</a>,
-top margin and bottom margin mean something slightly different than
-when you're  using just the typesetting macros (see
-<a href="typemacdoc.html#TB_MARGINS">Top and bottom margins in document processing</a>).
-<p>
-Additionally, if you invoke <strong>PAGE</strong> with a top margin
-argument, any macros you invoke after <strong>PAGE</strong> will
-almost certainly move the
-<a href="definitions.html#TERMS_BASELINE">baseline</a>
-of the first line of text down by one linespace.  To compensate, do
-<p>
-<pre>
-	.RLD 1v
-</pre>
-
-immediately before entering any text, or, if it's feasible, make
-<strong>PAGE</strong> the last macro you invoke prior to entering text.

-<br>
-<nobr>Macro: <strong>FAMILY</strong> &lt;family&gt;</nobr>
-<br>
-Alias: <strong>FAM</strong>
-
-<p>
-<strong>FAMILY</strong> takes one argument: the name of the
-<a href="definitions.html#TERMS_FAMILY">family</a>
-you want.  Groff comes with a number of PostScript families, each
-identified by a 1-, 2- or 3-letter mnemonic.  The standard families
-are:
-<table valign="baseline" summary="family">
-<tr><td width="15"><td><strong>A</strong><td>Avant Garde
-<tr><td><td><strong>BM</strong> <td>Bookman
-<tr><td><td><strong>H</strong><td>Helvetica
-<tr><td><td><strong>HN</strong><td>Helvetica Narrow
-<tr><td><td><strong>N</strong><td>New Century Schoolbook
-<tr><td><td><strong>P</strong><td>Palatino
-<tr><td><td><strong>T</strong><td>Times Roman</td></tr>
-<tr><td><td><strong>ZCM</strong><td>Zapf Chancery</td></tr>
-</table>
-<p>
-The argument you pass to <strong>FAMILY</strong> is the identifier at
-left, above.  For example, if you want Helvetica, enter
-<p>
-<pre>
-	.FAMILY H
-</pre>
-
-<strong>NOTE:</strong> The
-<a href="#FONT">font macro</a>
-(<strong>FT</strong>) lets you specify both the type family
-and the desired font with a single macro.  While this saves a few
-keystrokes, I recommend using <strong>FAMILY</strong> for family,
-and <strong>FT</strong> for font, except where doing so is genuinely
-inconvenient. <strong>ZCM</strong>, for example, only exists in one
-style: Italic (<strong>I</strong>).  Therefore, <kbd>.FT ZCMI</kbd>
-makes more sense than setting the family to &quot;ZCM&quot;, then
-setting the font to &quot;I&quot;.
-<p>
-<a name="FAM_ADD_NOTE"></a>
-<strong>ADDITIONAL NOTE:</strong> As of <strong>mom, version
-1.1.9-a</strong>, if you are running a version of groff lower
-than 1.19.2, you <em>MUST</em> follow all <strong>FAMILY</strong>
-requests with a <strong>FT</strong> request, otherwise
-<strong>mom</strong> will set all type up to the next
-<strong>FT</strong> request in the
-<a href="#FALLBACK_FONT">fallback font</a>.
-<p>
-If you are running a version of groff greater than or equal
-to 1.19.2, when you invoke the <strong>FAMILY</strong> macro,
-<strong>mom</strong> &quot;remembers&quot; the font style (Roman,
-Italic, etc) currently in use (if the font style exists in the new
-family) and will continue to use the same font style in the new
-family.  For example:
-<p>
-<pre>
-	.FAMILY BM   \" Bookman family
-	.FT     I    \" Medium Italic
-	&lt;some text&gt;  \" Bookman Medium Italic
-	.FAMILY H    \" Helvetica family
-	&lt;more text&gt;  \" Helvetica Medium Italic
-</pre>
-
-However, if the font style does not exist in the new family,
-<strong>mom</strong> will set all subsequent type in the
-<a href="#FALLBACK_FONT">fallback font</a>
-(by default, Courier Medium Roman) until she encounters a
-<a href="#FONT">.FT</a>
-request that's valid for the family.  For example, assuming
-you don't have the font &quot;Medium Condensed Roman&quot;
-(<strong>mom</strong> extension &quot;<strong>CD</strong>&quot;)
-in the Helvetica family:
-<p>
-<pre>
-	.FAMILY UN    \" Univers family
-	.FT     CD    \" Medium Condensed
-	&lt;some text&gt;   \" Univers Medium Condensed
-	.FAMILY H     \" Helvetica family
-	&lt;more text&gt;   \" Courier Medium Roman!
-</pre>
-
-In the above example, you must follow <kbd>.FAMILY H</kbd> with a
-<strong>FT</strong> request that's valid for Helvetica.
-<p>
-<strong>Experts:</strong>
-<br>
-If you add other PostScript families to groff's /font/devps directory,
-I recommend following the groff standard for naming families and fonts.
-For example, if you add the Garamond family, name the font files
-<p>
-<pre>
-	GARAMONDR
-	GARAMONDI
-	GARAMONDB
-	GARAMONDBI
-</pre>
-
-GARAMOND then becomes a legal family name you can pass to
-<strong>FAMILY</strong>.  (You could, of course, shorten GARAMOND to just
-G, or GD.)  R, I, B, and BI after GARAMOND are the roman, italic,
-bold and bold-italic fonts respectively.
-<p>
-Please see the Appendices,
-<a href="appendices.html#FONTS">Adding PostScript fonts to groff</a>,
-for information on adding fonts and families to groff, as well as
-to see a list of the extensions <strong>mom</strong> provides to
-groff's basic <strong>R, I, B, BI</strong> styles.

-
-<!---FT--->

-<a name="FONT"><h3><u>Font</u></h3></a>
-<br>
-<nobr>Macro: <strong>FT</strong> R | I | B | BI | &lt;any other valid font style&gt;</nobr>
-
-<p>
-By default, groff permits <strong>FT</strong> to take one of four
-possible arguments specifying the desired font:
-<table valign="baseline" summary="font">
-<tr><td width="15"><td><strong>R</strong><td> = <td>(Medium) Roman
-<tr><td><td><strong>I</strong><td> = <td>(Medium) Italic
-<tr><td><td><strong>B</strong><td> = <td>Bold (Roman)
-<tr><td><td><strong>BI</strong><td> = <td>Bold Italic</td></tr>
-</table>
-<p>
-For example, if your
-<a href="definitions.html#TERMS_FAMILY">family</a>
-is Helvetica, entering
-<p>
-<pre>
-	.FT B
-</pre>
-
-will give you the Helvetica bold
-<a href="definitions.html#TERMS_FONT">font</a>.
-If your family were Palatino, you'd get the Palatino bold font.
-<p>
-(As of <strong>mom, version 1.1.9-a,</strong> the range of arguments
-that can be passed to <strong>FT</strong> has been considerably
-extended, allowing access to a greater variety of font
-<a href="definitions.html#TERMS_WEIGHT">weights</a>
-and
-<a href="definitions.html#TERMS_SHAPE">shapes</a>.
-Please see the
-<a href="#FONT_NOTE">NOTE</a>,
-below.)
-<p>
-How <strong>mom</strong> reacts to an invalid argument to
-<strong>FT</strong> depends on which version of groff you're using.
-If your groff version is greater than or equal to 1.19.2,
-<strong>mom</strong> will issue a warning and, depending on how
-you've set up the
-<a href="#FALLBACK_FONT">fallback font</a>,
-either continue processing using the fallback font, or abort
-(allowing you to correct the problem).  If your groff version is less
-than 1.19.2, <strong>mom</strong> will silently continue processing,
-using either the fallback font or the font that was in effect prior
-to the invalid <strong>FT</strong> call.
-<p>
-<strong>FT</strong> will also accept, as an argument, a full
-family+font name.  For example,
-<p>
-<pre>
-	.FT HB
-</pre>
-
-will set subsequent type in Helvetica Bold.  However, I strongly
-recommend keeping family and font separate except where doing so is
-genuinely inconvenient.
-<p>
-For inline control of fonts, see
-<a href="inlines.html#INLINE_FONTS_MOM">Inline Escapes, font control</a>.
-<p>
-<a name="FONT_NOTE"></a>
-<strong>NOTE: mom, versions 1.1.9-a</strong> and higher,

-<br>
-<nobr>Macro: <strong>FALLBACK_FONT</strong> &lt;fallback font&gt; [ ABORT | WARN ] | ABORT | WARN</nobr>
-
-<p>
-In the event that you pass an invalid argument to
-<a href="#FONT">.FAMILY</a>
-(i.e. a non-existent family), <strong>mom</strong>, by default, uses
-the fallback font, Courier Medium Roman (CR), in order to continue
-processing your file.
-<p>
-If you'd prefer another fallback font, pass
-<strong>FALLBACK_FONT</strong> the <strong>full family+font name
-of the font you'd like</strong>.  For example, if you'd rather the
-fallback font were Times Roman Medium Roman,
-
-<pre>
-	.FALLBACK_FONT TR
-</pre>
-<p>
-would do the trick.
-<p>
-Additionally, if your version of groff accepts accepts &quot;if
-F&quot; and &quot;if S&quot; (see
-<a href="#FAM_ADD_NOTE">above</a>),
-<strong>mom</strong> issues a warning whenever a
-<strong>font style</strong> set with
-<a href="#FONT">.FT</a>
-does not exist, either because you haven't registered the style
-(see
-<a href="appendices.html#REGISTER_STYLE">here</a>
-for instructions on registering styles), or because the font style
-does not exist in the current family set with
-<a href="#FAMILY">.FAMILY</a>.
-By default, <strong>mom</strong> then aborts, which allows you to
-correct the problem.
-<p>
-If you'd prefer that <strong>mom</strong> not abort on non-existent
-fonts, but rather continue processing using a fallback font,
-you can pass <strong>FALLBACK_FONT</strong> the argument
-<strong>WARN</strong>, either by itself, or in conjunction with your
-chosen fallback font.
-<p>
-<strong>Some examples of invoking FALLBACK_FONT:</strong>
-<br>
-<ul>
-	<li><kbd>.FALLBACK_FONT WARN</kbd>
-		<br>
-		<strong>mom</strong> will issue a warning whenever you try
-		to access a non-existent font but will continue processing
-		your file with the default fallback font, Courier Medium Roman.
-	<li><kbd>.FALLBACK_FONT TR WARN</kbd>
-		<br>
-		<strong>mom</strong> will issue a warning whenever you try
-		to access a non-existent font but will continue processing
-		your file with a fallback font of Times Roman Medium Roman;
-		additionally, &quot;TR&quot; will be the fallback font whenever
-		you try to access a <strong>family</strong> that does not exist.
-	<li><kbd>.FALLBACK_FONT TR ABORT</kbd>
-		<br>
-		<strong>mom</strong> will abort whenever you try to access a
-		non-existent font, and will use the fallback font
-		&quot;TR&quot; whenever you try to access a <strong>family</strong>
-		that does not exist.
-</ul>
-<p>
-If, for some reason, you want to revert to ABORT, just enter
-<kbd>.FALLBACK_FONT ABORT</kbd> and <strong>mom</strong> will once
-again abort on font errors.

-<br>
-<em>*Does not require a <a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a></em>
-
-<p>
-<strong>PT_SIZE</strong> (Point Size) takes one argument: the size of type
-in points.  Unlike most other macros that establish the size or measure
-of something, <strong>PT_SIZE</strong> does not require that you supply a
-unit of measure since it's a near universal convention that type size
-is measured in points.  Therefore, to change the type size to, say,
-11 points, enter
-<p>
-<pre>
-	.PT_SIZE 11
-</pre>
-
-Point sizes may be fractional (e.g.  10.25 or 12.5).
-<p>
-You can prepend a plus or a minus sign to the argument to
-<strong>PT_SIZE</strong>, in which case the point size will be changed by +
-or - the original value.  For example, if the point size is 12,
-and you want 14, you can do
-<p>
-<pre>
-	.PT_SIZE +2
-</pre>
-
-then later reset it to 12 with
-<p>
-<pre>
-	.PT_SIZE -2
-</pre>
-
-The size of type can also be changed inline.  See
-<a href="inlines.html#INLINE_SIZE_MOM">Inline Escapes, changing point size</a>.
-<p>
-<strong>NOTE:</strong> It is unfortunate that the <kbd>pic</kbd>
-pre-processor uses <strong>PS</strong>, and thus
-<strong>mom</strong>'s macro for setting point sizes can't use it.
-However, if you aren't using <kbd>pic</kbd>, you might want to
-alias <strong>PT_SIZE</strong> as <strong>PS</strong>, since
-there'd be no conflict.
-<p>
-<pre>
-	.ALIAS PS PT_SIZE

-<br>
-<em>*Does not require a <a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a></em>
-
-<p>
-<strong>LS</strong> (Line Space) takes one argument: the distance you want, typically
-in points, from baseline to baseline of type.  The argument may
-be fractional (e.g. 12.25 or 14.5).  Like <strong>PT_SIZE</strong>,
-<strong>LS</strong> does not require a unit of measure, since
-<a href="definitions.html#TERMS_LEADING">leading</a>
-is most often given in points.  Therefore, to set the linespace to
-14 points, you would enter
-<p>
-<pre>
-	.LS 14
-</pre>
-
-However, if you wish, you may specify a unit of measure by appending
-it directly to the argument passed to <strong>LS</strong>.  For example,
-if you want a linespace of 1/4 of an inch, enter
-<p>
-<pre>
-	.LS .25i
-</pre>
-
-You can prepend a plus or a minus sign to the argument to
-<strong>LS</strong>, in which case the line spacing will be changed
-by + or - the original value.  For example, if the line spacing is
-14 points, and you want 17 points, you can do
-<p>
-<pre>
-	.LS +3
-</pre>
-
-then later reset it to 14 points with
-<p>
-<pre>
-	.LS -3
-</pre>
-
-<strong>Experts:</strong>
-<br>
-<strong>LS</strong> should not be confused with the groff primitive
-<strong>ls</strong>.  <strong>LS</strong> acts like <strong>vs</strong>.
-<strong>mom</strong> does not provide a macro analogous to

-<br>
-<em>*Does not require a <a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a></em>
-
-<p>
-Without the <strong>FACTOR</strong> argument, <strong>AUTOLEAD</strong>
-calculates the linespace for you by adding its argument to the
-current point size of type. All subsequent <strong>PT_SIZE</strong>
-requests automatically update the linespacing by the autolead amount.
-<p>
-Used in this way, <strong>AUTOLEAD</strong> does not require a unit
-of measure; points is assumed.  However, you may use an alternate
-unit of measure by appending it to the argument.  The argument may
-be a decimal fraction (e.g. .5 or 2.75).
-<p>
-As an example, if your current point size of type is 12, entering
-<p>
-<pre>
-	.AUTOLEAD 2
-</pre>
-
-changes the linespace to 14 points, regardless any linespacing
-already in effect.  From here on, every change to the size of type
-(with <strong>PT_SIZE</strong>, not
-<a href="definitions.html#TERMS_INLINES">inline</a>)
-changes the linespace as well.  If you decrease the type size to 9
-points, the leading decreases to 11 points.  If you increase the type
-size to 16 points, the leading increases to 18 points.
-<p>
-Automatic updating of the linespacing continues until you enter a
-&quot;manual&quot; line space value with <strong>LS</strong>.
-<p>
-If you give <strong>AUTOLEAD</strong> the optional
-<strong>FACTOR</strong> argument, <strong>AUTOLEAD</strong>
-calculates the line space as a factor of the
-<a href="definitions.html#TERMS_NUMERICARGUMENT">numeric argument</a>
-you gave <strong>AUTOLEAD</strong>.  For example, if your point
-size is 12,
-<p>
-<pre>
-	.AUTOLEAD 1.125 FACTOR
-</pre>
-sets the leading at 13.5 points.  If you change the point size
-to 14, the leading automatically changes to 15.75 (14 x 1.125).
-<p>
-<strong>NOTE:</strong> There's no need to prepend a plus sign (+)
-to <strong>AUTOLEAD</strong>'s argument, although you may do so if you
-wish.

-<br>
-<em>*Requires a <a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a></em>
-
-<p>
-<strong>LL</strong> (Line Length) takes one argument: the distance from the
-left margin of the page to the maximum allowable point on the
-right at which groff should place type.  The line length, in
-other words, as the macro suggests.
-<p>
-<strong>LL</strong> requires a unit of measure.  Therefore, to set the line
-length to 39 picas, you would enter
-<p>
-<pre>
-	.LL 39P
-</pre>
-
-As with other macros that require a unit of measure, the argument to
-<strong>LL</strong> may be fractional.  For example,
-<p>
-<pre>
-	.LL 4.5i
-</pre>
-
-sets the line length to 4-1/2 inches.
-
-<p>
-Additionally, you may express a new line length relative to the
-current line length by prepending a plus or minus sign to the
-argument.  Thus, if you wanted to increase the line length by 3
-<a href="definitions.html#TERMS_PICASPOINTS">points</a>, you could
-do
-<p>
-<pre>
-	.LL +3p
-</pre>
-
-This is especially handy when you want to &quot;hang&quot;
-punctuation outside the right margin since you can pass groff's
-<a href="inlines.html#INLINE_STRINGWIDTH_GROFF"><strong>\w</strong></a>
-escape as the argument to <strong>LL</strong>, like this:
-<p>
-<pre>
-	.LL +\w'.'u
-</pre>
-
-The above example increases the current line length by the width of
-a period.  Notice that you must append the
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>,
-<strong>u</strong>, to the escape since .LL requires a unit of

-
-<p>
-Most of the time, you won't need the <strong>BR</strong> macro.
-In fill modes, <strong>mom</strong> tries to be sensible about
-where breaks are needed.  If the nature of a macro is such that under
-most circumstances you'd expect a break, <strong>mom</strong> puts

-<p>
-<strong>NOTE:</strong> Lines of text in

-<br>
-*EL does not work after the PAD macro.
-See
-<a href="goodies.html#PAD">PAD</a>
-for the way around this</em>.
-<p>
-The mnemonic "EL" is borrowed from old Compugraphic typesetting
-systems, where it stood for "End Line."  Conceptually,
-<strong>EL</strong> is equivalent to the notion of a carriage return
-with no linefeed.
-
-<p>
-<em>Note to groff jocks:</em> <strong>EL</strong> is
-unrelated to groff's <strong>.el</strong>.  If you find the
-similarity confusing, you may want to alias <strong>EL</strong> as
-something else (but don't use <strong>EOL</strong>; it's already
-taken.)
-
-<p>
-<strong>EL</strong>'s function is simple: it breaks a line without
-advancing on the page.
-<a name="EL_EXAMPLE">As</a>
-an example of where you might use it,
-imagine that you're working from marked-up copy.  The markup
-indicates 24 points of space between two given lines, but the
-prevailing line spacing is 12.5 points.  You may find it more
-convenient to break the first line with <strong>EL</strong> and
-instruct <strong>mom</strong> to advance 24 points to the next line
-instead of calculating the lead that needs to be added to 12.5 to
-get 24.  To demonstrate:
-<p>
-<pre>
-	.LEFT
-	.LS 12.5
-	A line of text.\c
-	.EL
-	.ALD 24p
-	The next line of text.
-</pre>
-
-may be more intuitive than
-<p>
-<pre>
-	.LEFT
-	.LS 12.5
-	A line of text.
-	.ALD 11.5p
-	The next line of text.
-</pre>
-
-The first example has the further advantage that should you wish
-to change the prevailing line space but keep the 24 points lead,
-you don't have to recalculate the extra space.
-<p>
-"ALD" in the above examples stands for "<strong>A</strong>dvance
-<strong>L</strong>ea<strong>D</strong>" (another mnemonic borrowed
-from Compugraphic), which is covered in the section
-<a href="#ALDRLD">Vertical movement</a>.
-<p>
-<a name="EL_NOTES"><strong>NOTES:</strong></a>

-<p>

-<a name="WS"><h3><u>Word spacing</u></h3></a>
-<br>
-<nobr>Macro: <strong>WS</strong> &lt;+|-wordspace&gt; | DEFAULT</nobr>
-
-<p>
-<strong>WS</strong> (Word Space) increases or decreases the amount
-of space between words.  In
-<a href="definitions.html#TERMS_NOFILL">nofill modes</a>,
-or if
-<a href="#QUAD">QUAD</a>
-is in effect, the space between words is fixed.  Therefore, if you
-change the word spacing with <strong>WS</strong>, the change applies
-uniformly to the space between every word on every line.  However,
-when text is
-<a href="definitions.html#TERMS_JUST">justified</a>,
-the space between words varies from line to line (in order to justify
-the text).  Consequently, the change you make with <strong>WS</strong>
-represents the minimum (and ideal) space groff will try to put between
-words before deciding whether to hyphenate a final word or to stretch
-the word spacing.
-
-<p>
-Word space is relative to type size.  Knowing how it's calculated is
-unimportant. What matters is having a sense of how the value passed
-to <strong>WS</strong> affects the look of your type.  Generally,
-in/decreasing the word space by a value of 1 or 2 produces a difference
-that in many cases is scarcely visible; in/decreasing by a value of 5
-or so produces a subtle but noticeable difference; and in/decreasing
-by a value greater than 10 is always apparent.  You should preview
-your work to assess the effect of <strong>WS</strong>.
-
-<p>
-<a name="WS_USAGE"><strong>WS</strong></a>
-takes as its argument a whole number preceded by a plus or minus sign.
-Therefore, to decrease the word space slightly, you might enter
-<p>
-<pre>
-	.WS -4
-</pre>
-
-To increase it by a noticeable amount, you might enter
-<p>
-<pre>
-	.WS +12
-</pre>
-
-You can reset the word spacing to its previous value by switching
-the plus or minus sign, like this:
-<p>
-<pre>
-	.WS +4
-	A line of text
-	.WS -4
-</pre>
-
-The <code>.WS -4</code> undoes the effect of <code>.WS
-+4</code>.  You can also reset <strong>WS</strong> to
-its groff default by entering
-<p>
-<pre>
-	.WS DEFAULT
-</pre>
-
-This can be particularly useful if you've been playing around
-with plus and minus values, and can't remember by how much you
-have to in/decrease the word space to get it back to normal.

-<!---SS--->

-<a name="SS"><h3><u>Sentence space</u></h3></a>
-<br>
-<nobr>Macro: <strong>SS</strong> &lt;+sentence space&gt; | 0 | DEFAULT</nobr>
-
-<p>
-<strong>SS</strong> (Sentence Space) tells groff how to treat double
-spaces it encounters between sentences in
-<a href="definitions.html#TERMS_INPUTLINE">input lines</a>.
-If you use <strong>SS</strong>, input sentences with two spaces
-after them AND input sentences that fall at the end of input lines
-all receive a normal word space plus an additional amount of space
-whose size is determined by the + value passed as an argument to
-<strong>SS</strong>.  Thus,
-<p>
-<pre>
-	.SS +2
-</pre>
-
-means that input sentences with two spaces after them receive a normal
-word space PLUS the +2 value passed to <strong>SS</strong>.
-<p>
-Like
-<strong>WS</strong>, increasing the sentence space by a value of
-1 or 2 produces a difference that in many cases is scarcely visible;
-increasing by a value of 5 or so produces a subtle but noticeable
-difference (i.e. the space between double-spaced input sentences will
-be slightly but visibly greater than the space between words); and
-increasing by a value greater than 10 is always apparent.  You should
-preview your work to assess the effect of <strong>SS</strong>.
-<p>
-There's an additional argument you can pass <strong>SS</strong>:
-the number zero (without the + sign).  It's the argument you'll
-use most often.  Typeset copy should never have two spaces between
-sentences, and the "zero" argument tells groff to give the extra
-spaces no space at all (effectively removing them).  Therefore,
-if you double-space your sentences (as you should when writing in a
-text editor), get in the habit of putting
-<p>
-<pre>
-	.SS 0
-</pre>
-
-at the top of your files.
-
-<p>
-If you do use <strong>SS</strong> for something other than ensuring
-that you don't get unwanted sentence spaces in output copy, you
-can set or reset the sentence space to the groff default (the same
-width as a word space, i.e. double-spaced input sentences will appear
-double-spaced on output as well) with
-<p>
-<pre>
-	.SS DEFAULT
-</pre>
-
-If you're using the
-<a href="docprocessing.html">document processing macros</a>
-and your
-<a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE</a>
-is <strong>TYPEWRITE</strong>, <code>.SS DEFAULT</code> is the default,
-because you <em>do</em> want double spaces between sentences in copy
-that imitates the look of a typewritten document.
-<p>
-<strong>IMPORTANT: SS</strong> with an argument other than
-&quot;0&quot; should only be used if you're of the old (and wise)
-school of typists that puts two spaces between sentences.  If you
-ignore this advice and use <strong>SS</strong> when you habitually
-put only one space between sentences, you risk producing output where
-the space between sentences is not equal.

-<br>
-<nobr>Macro: <strong>HY</strong> DEFAULT</nobr>
-<br>
-Aliases: <strong>HYPHENATE, HYPHENATION</strong>
-
-<p>
-<strong>HY</strong>, as you can see, can be invoked with a number of
-arguments.  In all cases, the aliases <strong>HYPHENATE</strong>
-or <strong>HYPHENATION</strong> can be used in place of
-<strong>HY</strong>.  To aid in understanding the various arguments
-you can pass to <strong>HY</strong>, I've broken them down into
-separate sections.
-
-<h3><u>1. HY</u></h3>
-<strong>HY</strong> by itself (i.e. with no argument) simply turns
-automatic hyphenation on.  Any argument other than <strong>LINES,
-MARGIN, SPACE</strong> or <strong>DEFAULT</strong>, turns automatic
-hyphenation off.  For example, as explained in
-<a href="intro.html#MACRO_ARGS">How to read macro arguments</a>,
-you could turn <strong>HY</strong> off by entering
-<p>
-<pre>
-	.HY OFF
-	   or
-	.HY X
-	   or
-	.HY END
-</pre>
-
-<strong>HY</strong> observes the following default hyphenation rules:
-<br>
-<ol>
-	<li>Last lines (i.e. ones that will spring a trap--typically
-	the last line on a page) will not be hyphenated.
-	<li>The first and last two characters of a word are never
-	split off.
-</ol>
-
-<h3><u>2. HY LINES</u></h3>
-<strong>HY LINES</strong> sets the maximum number of consecutive
-hyphenated lines that will appear in output copy.  2 is a very
-good choice, and you'd set it with
-<p>
-<pre>
-	.HY LINES 2
-</pre>
-
-By default, when you turn automatic hyphenation on, there is no
-limit to the number of consecutive hyphenated lines.
-
-<p>
-<strong>NOTE:</strong>
-<a href="definitions.html#TERMS_DISCRETIONARYHYPHEN">Discretionary hyphens</a>
-count when groff is figuring out how many lines to hyphenate;
-explicit hyphens do not.
-
-<h3><u>3. HY MARGIN</u></h3>
-<strong>HY MARGIN</strong> sets the amount of room allowed at
-the end of a line before hyphenation is tripped (e.g. if there's
-only 6 points left at the end of a line, groff won't try to hyphenate
-the next word).  <strong>HY MARGIN</strong> only applies if you're
-using
-<a href="#QUAD">QUAD</a>, and is really only useful if you're
-using <strong>QUAD LEFT</strong>.
-
-<p>
-As an example, if you don't want groff to hyphenate words when there's
-only 18 points of space left at the end of a left-quadded line,
-you'd enter
-<p>
-<pre>
-	.HY MARGIN 18p
-</pre>
-
-<strong>NOTE:</strong> The numeric argument after <strong>HY
-MARGIN</strong> requires a
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>.
-
-<h3><u>4. HY SPACE</u></h3>
-<strong>HY SPACE</strong> sets an amount of extra interword
-space that groff will <em>try</em> to put between words on a
-line in order to PREVENT hyphenation.  <strong>HY SPACE</strong>
-applies only to
-<a href="definitions.html#TERMS_JUST">justified lines</a>.  Generally speaking,
-you'll want this value to be quite small, since too big a value
-will result in lines with gaping holes between the words.  A reasonable
-value might be half a point, or one point, which you'd set with
-<p>
-<pre>
-	.HY SPACE .5p
-	    or
-	.HY SPACE 1p
-</pre>
-
-<strong>NOTE:</strong> The numeric argument after <strong>HY
-SPACE</strong> requires a
-<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>.
-
-<h3><u>5. HY DEFAULT</u></h3>
-<strong>HY DEFAULT</strong> resets automatic hyphenation to its
-default behaviour, cancelling any changes made with <strong>LINES,
-MARGIN,</strong> and/or <strong>SPACE</strong>.
-
-<h3><u>A note on hyphenation in general</u></h3>
-Hyphenation is a necessary evil.  If it can be avoided, it should be.
-If it can't be, it should occur infrequently.  That's the reason for
-the number of parameters you can set with <strong>HY</strong>.
-
-<p>
-Furthermore, hyphenation in
-<a href="definitions.html#TERMS_RAG">rag</a>
-copy requires a great deal of attention.  At best, it should be
-avoided completely by individually adjusting the number of words
-on consecutive lines to achieve a pleasing, natural-looking rag.  
-Since such adjustments are often too fussy for document
-processing, I recommend playing around with <strong>HY MARGIN</strong>
-a bit if your copy looks hyphen-heavy.

-	<h2><u>Tabs</u></h2>
-</a>
-
-<strong>Mom</strong> provides two different kinds of tab setup:
-typesetting tabs and string tabs.  Neither one has anything to
-do with the tab key on your keyboard, and both are utterly
-divorced from groff's notion of tabs.  I recommend reading this
-section carefully in order to understand how
-<strong>mom</strong> handles tabs.
-<p>
-<strong>NOTE:</strong> see the section
-<a href="typemacdoc.html#TYPESETTING">Using typesetting macros during document processing</a>
-for re-assuring information on the use of tabs during
-<a href="docprocessing.html#DOCPROCESSING">document processing</a>.
-<p>
-
-<a name="TYPESETTING_TABS"><h3><u>Typesetting tabs</u></h3></a>
-<p>
-Typesetting tabs are defined by both an indent from the left margin and
-a line length.  This is quite different from typewriter-style tab stops
-(the groff norm) that only define the left indent.  In conjunction
-with the
-<a href="#MULTI_COLUMNS">multi-column macros</a>,
-typesetting tabs significantly facilitate
-tabular and columnar work.
-<p>
-Typesetting tabs are created with the
-<a href="#TAB_SET">TAB_SET</a>
-macro. <strong>TAB_SET</strong> identifies the tab (by number),
-establishes its left indent and line length, and optionally sets
-a quad direction and fill mode.  After tabs have been created with
-<strong>TAB_SET</strong>, they can be called at any time with the
-<a href="#TAB">TAB</a>
-macro.
-<p>
-
-<a name="TYPESETTING_TABS_TUT"><h3><u>Quickie tutorial on typesetting tabs</u></h3></a>

-Say you want to set up three tabs to produce an employee evaluation
-that looks something like this:

-	Service           Good         Many clients specifically request
-	                               support from Joe by name.
-
-	Punctuality    Satisfactory    Tends to arrive after 8:00am, but
-	                               often works through lunch hour.
-
-	Team spirit     Needs work     Persistently gives higher priority

-	                               organizational hierarchy.
-</pre>
-
-You want the first tab (&quot;CRITERION&quot;)
-<br>
-<ul>
-	<li>to begin at the left margin of the page (i.e. no indent)
-	<li>to have a line length of 5 picas
-	<li>to be set flush left
-</ul>
-<br>
-Tabs must be numbered, and each has to be set up with a separate
-<a href="#TAB_SET">TAB_SET</a>
-line.  Therefore, to set up tab 1, you enter
-<p>
-<pre>
-   .TAB_SET  1  0  5P  L
-             |  |  |   |
-      tab #__|  |  |   |__direction
-                |  |
-        indent__|  |__length

-
-You want the second tab (&quot;EVALUATION&quot;)
-<br>
-<ul>
-	<li>to begin 8 picas from the left margin
-	<li>to have a length of 9 picas
-	<li>to be set centred.
-</ul>
-<br>
-You set it up like this:
-<p>
-<pre>
-   .TAB_SET  2  8P  9P  C
-             |  |   |   |
-      tab #__|  |   |   |__direction
-                |   |
-        indent__|   |__length
-</pre>
-
-You want the third tab (&quot;COMMENTS&quot;)
-<br>
-<ul>
-	<li>to begin 19 picas from the left margin
-	<li>to have a length of 17 picas
-	<li>to be set flush left, <a href="definitions.html#TERMS_FILLED">filled</a>
-</ul>
-<br>
-The setup looks like this:
-<p>
-<pre>
-   .TAB_SET  3  19P  17P  L  QUAD
-             |   |    |   |    |

-                 |    |
-         indent__|    |__length
-</pre>
-
-Once the tabs are set up, you can call them in one of two ways:
-<br>
-<ul>
-	<li><a href="#TAB">TAB</a> (with the tab
-		number as an argument) breaks the current line,
-		advances one linespace, and calls the tab.
-	<li><a href="#TN">TN</a> (Tab Next) keeps
-		you on the current line and moves over to the next
-		tab in sequence (i.e. from 1 to 2, 2 to 3, etc.).
-</ul>
-<br>
-To exit from tabs and restore your original left margin, line length,
-quad direction and fill mode,  use
-<a href="#TQ">TQ</a>
-(Tab Quit).
-<p>
-Here's how the input for our sample employee evaluation looks
-(with some introductory parameters):
-<p>
-<pre>
-	.PAGE 8.5i 11i 1i 1i 1i
-	.FAMILY  T

-Setting up string tabs is a two-step procedure.  First, you enter an

-macro for every string tab you defined, and optionally pass quad and
-fill information to it.  That done, string tabs are called with
-the
-<a href="#TAB">TAB</a>
-macro, just like typesetting tabs.

-<a name="STRING_TABS_TUT"><h3><u>Quickie tutorial on string tabs</u></h3></a>
-<p>
-Say you want to set up tabs for the
-<a href="#TYPSETTING_TABS_SAMPLE">employee evaluation form</a>
-used as an example in the
-<a href="#TYPESETTING_TABS_TUT">typesetting tabs tutorial</a>.
-This time, though, you want to play around with the point size of
-type, so you can't know exactly how long the tabs will be or where
-they should start.  All you know is
-<br>
-<ul>
-	<li>CRITERION is the longest line in tab 1
-	<li>EVALUATION is the longest line in tab 2
-	<li>tab 3 should extend to the current right margin
-	<li>you want a 1 pica gutter between each tab
-</ul>
-<br>
-This is an ideal job for string tabs.
-<p>
-The first thing you need for string tabs is an
-<a href="definitions.html#TERMS_INPUTLINE">input line</a>
-with tab positions marked on it.  Tabs are marked with the
-<a href="definitions.html#TERMS_INLINES">inline escapes</a>
-<a href="#ST_INLINE">\*[ST&lt;n&gt;]</a>
-and
-<a href="#ST_INLINE">\*[ST&lt;n&gt;X]</a>,
-where <strong>&lt;n&gt;</strong>
-is the number you want the tab to have.  (In this example, we
-enclose the input line with the
-<a href="goodies.html#SILENT">SILENT</a>
-macro so the line doesn't print.  We also use the
-<a href="goodies.html#PAD">PAD</a>
-macro to permit defining tab 3 as simply &quot;the amount of
-space remaining on the input line.&quot;)
-<p>
-The setup looks like this:
-<p>
-<pre>
-	.SILENT
-	.PAD "\*[ST1]CRITERION\*[ST1X]\*[FWD 12p]\*[ST2]EVALUATION\*[ST2X]\*[FWD 12p]\*[ST3]#\*[ST3X]"
-	.SILENT OFF
-</pre>
-
-The long line after <kbd>.PAD</kbd> looks scary, but it isn't.
-Here's what it means when broken down into its component parts:
-<br>
-<ul>
-	<li>The longest line in tab 1 is &quot;CRITERION&quot;, so we
-		enclose CRITERION with begin/end markers for string tab 1:
-		<p>
-		<kbd>\*[ST1]CRITERION\*[ST1X]</kbd>
-		<br>
-	<li>We want a 1 pica (12 points) gutter between tab 1 and 2,
-		so we insert 12 points of space with \*[FWD 12p]
-		(<strong>F</strong>or<strong>W</strong>ar<strong>D</strong> 12 points):
-		<p>
-		<kbd>\*[FWD 12p]</kbd>
-		<br>
-	<li>The longest line in tab 2 is &quot;EVALUATION&quot;, so
-		we enclose EVALUATION with begin/end markers for string
-		tab 2:
-		<p>
-		<kbd>\*[ST2]EVALUATION\*[ST2X]</kbd>
-		<br>
-	<li>We want 1 pica (12 points) between tab 2 and 3, so we
-		insert 12 points of space with another \*[FWD 12p]:
-		<p>
-		<kbd>\*[FWD 12p]</kbd>
-		<br>
-	<li>We want tab 3 to be as long as whatever space remains on
-		the current line length, so we enclose the
-		<a href="goodies.html#PAD_MARKER">pad marker</a>
-		(#) with begin/end markers for string tab 3:
-		<p>
-		<kbd>\*[ST3]#\*[ST3X]</kbd>
-		<br>
-</ul>
-<br>
-The tabs are now defined, but they require
-<a href="definitions.html#TERMS_QUAD">quad direction</a>
-and
-<a href="definitions.html#TERMS_FILLED">fill</a>
-information.  For each string tab defined above, enter a
-separate
-<a href="#ST">ST</a>
-line, like this:
-<p>
-<pre>
-	.ST  1  L
-	.ST  2  L
-	.ST  3  L  QUAD
-	     |  |   |
-	     |  |   |__fill output lines
-	     |  |
-	tab__|  |__direction
-	number
-</pre>
-
-From here on in, you call the tabs with
-<a href="#TAB">TAB</a>
-and
-<a href="#TN">TN</a>
-just like typesetting tabs (see
-<a href="#TYPESETTING_TABS_TUT">typesetting tabs tutorial</a>).
-<p>
-Here's the complete setup and entry for the sample employee
-evaluation form utilizing string tabs.

-Try setting this up and previewing it with

-<pre>
-	groff -mom -X &lt;filename&gt;
-</pre>
-
-Now, change the point size of the above sample to 12 and preview
-it again.  You'll see that the tab structure remains identical (tab
-1=CRITERION, tab 2=EVALUATION, tab 3=space remaining, and the gutter
-between tabs is still 1 pica), while the position and length 
-of the tabs have altered because of the new point size.
-<p>
-Now try increasing the gutters to 2 picas (<kbd>\*[FWD 24p]</kbd> or
-<kbd>\*[FWD 2P]</kbd> instead of <kbd>\*[FWD 12p]</kbd>).  Preview the
-file again, and notice how the tab structure remains the same, but
-the gutters are wider.

-<nobr>Macro: <strong>TAB_SET</strong> &lt;tab number&gt; &lt;indent&gt; &lt;length&gt;  L | R | C | J [ QUAD ]</nobr>

-<em>*&lt;indent&gt; and &lt;length&gt; require a <a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a></em>
-
-<p>
-<strong>TAB_SET</strong> creates typesetting tabs that later can be
-called with
-<a href="#TAB">TAB</a>.
-Typesetting tabs are numbered, and defined by an indent, a length,
-and a &quot;direction&quot;, hence <strong>TAB_SET</strong> has
-four required arguments:
-<br>
-<ul>
-	<li>a tab number
-	<li>an indent (measured from the left margin of the page,
-	or, if you're already in a tab, from the left margin of the tab)
-	<li>a length
-	<li>a direction
-</ul>
-<br>
-To set up a centred tab 6 picas long and 9 points from the left
-margin, you'd enter
-<p>
-<pre>
-	.TAB_SET 1 9p 6P C
-</pre>
-
-The tab number in the above (&quot;1&quot;) is simply an
-identifier.  It could have been 4, or 17, or 296.  There's no
-need to set up tabs in numerical sequence.
-<p>
-By default, tabs are in
-<a href="definitions.html#TERMS_NOFILL">nofill</a>
-mode, meaning you can enter text in tabs on a line-for-line basis
-without having to use the
-<a href="#BR">BR</a>
-macro.  If you want a tab to be
-<a href="definitions.html#TERMS_FILLED">filled</a>,
-pass the optional argument <strong>QUAD</strong>, which will
-make the tab behave as if you'd entered <kbd>.QUAD L | R |
-C</kbd>.
-<p>
-For
-<a href="definitions.html#TERMS_JUST">justified</a>
-tabs, simply pass the argument <strong>J</strong> (without the
-<strong>QUAD</strong> argument), like this:
-<p>
-<pre>
-	.TAB 1 9p 6P J
-</pre>
-
-Once tabs are set, they can be called at any time with the
-<a href="#TAB">TAB #</a>
-macro, where &quot;#&quot; is the number of the desired tab.
-<p>
-You can set up any number of typesetting tabs.  However, be
-aware that
-<a href="#STRING_TABS">string tabs</a>
-are also called with <strong>TAB #</strong>, so be careful that you
-don't set up a typesetting tab numbered, say, 4, when you already
-have a string tab numbered 4.  Every tab, typesetting or string,
-must have a unique numeric identifier.
-<p>
-<strong>NOTE:</strong> If you use <strong>TAB_SET</strong> while
-you're currently inside a tab, the indent argument is the distance from
-the tab's left margin, not the left margin of the page.  Therefore,
-you should exit tabs (with
-<a href="#TQ">TQ</a>)
-before creating new tabs (unless, of course, you want to set
-up a tab structure within the confines of an existing tab).
-<p>
-<strong>IMPORTANT:</strong> Turn all indents off (see
-<a href="#INDENTS">Indents</a>)
-before setting up tabs with <strong>TAB_SET</strong>, or
-<strong>mom</strong> may get confused.

-String tabs need to be marked off with

-before being set up with the
-<a href="#ST">ST</a>
-macro.  Any input line may contain string tab markers.
-<i>&lt;number&gt;</i>, above, means the numeric identifier of
-the tab.  The following shows a sample input line with string
-tab markers.
-<p>
-<pre>
-	\*[ST1]Now is the time\*[ST1X] for all \*[ST2]good men\*ST2X] to come to the aid of the party.
-</pre>
-
-String tab 1 begins at the start of the line and ends after the word
-&quot;time&quot;.  String tab 2 starts at &quot;good&quot; and ends
-after &quot;men&quot;.  Inline escapes (e.g. font or point size
-changes, or horizontal movements, including
-<a href="goodies.html#PAD">padding</a>)
-are taken into account when <strong>mom</strong> determines the
-position and length of string tabs.
-<p>
-Up to nineteen string tabs may be marked (not necessarily all on
-the same line, of course), and they must be numbered between 1
-and 19.
-<p>
-Once string tabs have been marked in input lines, they have to
-be &quot;set&quot; with
-<a href="#ST">ST</a>,
-after which they may be called, by number, with
-<a href="#TAB">TAB</a>.
-<p>
-<strong>NOTE:</strong> Lines with string tabs marked off in them
-are normal input lines, i.e. they get printed, just like any
-input line.  If you want to set up string tabs without the line
-printing, use the
-<a href="#SILENT">SILENT</a>
-macro.

-<a name="IMPORTANT"><strong>IMPORTANT:</strong></a>
-Owing to the way groff processes
-<a href="definitions.html#TERMS_INPUTLINE">input lines</a>
-and turns them into
-<a href="definitions.html#TERMS_OUTPUTLINE">output lines</a>,
-it is not possible for <strong>mom</strong> to &quot;guess&quot; the
-correct starting position of string tabs marked off in lines that
-are centered or set flush right.
-<p>
-Equally, she cannot guess the starting position if a line is fully
-justified and broken with
-<a href="#SPREAD">SPREAD</a>.
-<p>
-In other words, in order to use string tabs,
-<a href="#LRC">LEFT</a>
-must be active, or, if
-<a href="#QUAD">QUAD LEFT</a>
-or
-<a href="#JUSTIFY">JUSTIFY</a>
-are active, the line on which the string tabs are marked must be
-broken &quot;manually&quot; with
-<a href="#BR">BR</a>
-(but not
-<a href="#SPREAD">SPREAD</a>).
-<p>
-To circumvent this behaviour, I recommend using the
-<a href="goodies.html#PAD">PAD</a>
-to set up string tabs in centered or flush right lines.  Say, for
-example, you want to use a string tab to underscore the text of a

-	<h2><u>Indents</u></h2>
-</a>
-
-With <strong>mom</strong>'s indents, you can indent from the left,
-the right, or both margins.  In addition, <strong>mom</strong>
-provides temporary left indents (i.e. only one line is indented,
-as at the start of a paragraph) and &quot;hanging&quot; left indents
-(the reverse of a temporary indent; the first line isn't indented,
-subsequent lines are).
-<p>
-<a name="INDENTS_TUT"><h3><u>A brief explanation of how mom handles indents</u></h3></a>
-<p>
-<strong>Mom</strong> provides five kinds of indents: left, right,
-both, temporary, and hanging.  Each is invoked by its own name:
-<br>
-<ul>
-	<li><strong>IL</strong> = <strong>I</strong>ndent <strong>L</strong>eft
-	<li><strong>IR</strong> = <strong>I</strong>ndent <strong>R</strong>ight
-	<li><strong>IB</strong> = <strong>I</strong>ndent <strong>B</strong>oth
-	<li><strong>HI</strong> = <strong>H</strong>anging <strong>I</strong>ndent
-	<li><strong>TI</strong> = <strong>T</strong>emporary <strong>I</strong>ndent
-</ul>
-<br>
-In addition, there are four macros to control exiting from
-indents:
-<br>
-<ul>
-	<li><strong>IQ</strong>&nbsp;&nbsp;= quit all active indents
-	<li><strong>ILX</strong>&nbsp;= exit indent style left
-	<li><strong>IRX</strong>&nbsp;= exit indent style right
-	<li><strong>IBX</strong>&nbsp;= exit indent style both
-</ul>
-<br>
-This section deals exclusively with <strong>IL, IR</strong> and
-<strong>IB</strong>.  For an explanation
-of hanging and temporary indents -- how they work and how to use
-them -- see
-<a href="#HI">Hanging indents</a>
-and
-<a href="#TI">Temporary indents</a>.
-<p>
-The first time you invoke any of <strong>mom</strong>'s indents,
-you must supply a measure.  For example,
-<p>
-<pre>
-	.IL 2P
-</pre>
-
-indents text 2 picas from the left margin (or current tab
-indent).
-<p>
-When you want to exit the above indent, use either
-<p>
-<pre>
-	.IQ
-	 or
-	.ILX
-</pre>
-
-The next time you want the same indent, invoke it without the
-argument, like this:
-<p>
-<pre>
-	.IL
-</pre>
-
-As you can see, once you've supplied a measure to an indent macro
-<strong>mom</strong> stores the value, obviating the need to repeat
-it on subsequent invocations.  And <strong>mom</strong> doesn't just
-store the measure -- she hangs on to it tenaciously.  Arguments passed
-to <strong>IL, IR</strong> and <strong>IB</strong> are additive.
-Consider the following:
-<p>
-<pre>
-	.LL 20P
-	.IR 2P    \"Indent right by 2 picas
-	A first block of text...
-	...
-	...
-	.IQ       \"Turn indent off
-	A second block of text...
-	...
-	...
-	.IR 2P    \"Indent right by an additional 2 picas (i.e. 4 picas)
-	A third block of text...
-	...
-	...
-</pre>
-
-The first block of text is right indented by 2 picas (i.e. the line
-length is shortened by 2 picas to 18 picas).  The second block of
-text, after <strong>IQ</strong>, is, as you'd expect, set to the full
-measure.  The third block of text -- the one to pay attention to --
-is not right indented by 2 picas, but rather by 4 picas.
-<strong>Mom</strong> adds the value of arguments to <strong>IL,
-IR</strong> and <strong>IB</strong> to whatever value is already
-in effect. 
-<p>
-If you wanted the third block of text in the example above to
-be right indented by just 2 picas (the original measure given to
-<strong>IR</strong>), you would enter <kbd>.IR</kbd> without an
-argument.
-<p>
-Because indent arguments are additive, putting a minus sign in front
-of the argument can be used to subtract from the current value.
-In the following example, the first line is indented 18 points, the
-second is indented 36 points (18+18), and the third is again indented
-18 points (36-18).
-<p>
-<pre>
-	.IL 18p     \"Indent left by 18 points      = 18 points
-	Now is the time
-	.IL 18p     \"Indent left by 18 points more = 36 points
-	for all good men to come
-	.IL -18p    \"Indent left by 18 points less = 18 points
-	to the aid of the party.
-</pre>
-
-Sometimes, you may want to clear out the stored indent values -- let
-<strong>mom</strong> start indenting with a clean slate, as it were.
-Giving the optional argument <kbd>CLEAR</kbd> to any of the
-&quot;indent quit&quot; macros resets them to zero.
-<br>
-<ul>
-	<li><strong>IQ CLEAR</strong>&nbsp;&nbsp;= quit and clear all indents
-	<li><strong>ILX CLEAR</strong>&nbsp;= quit and clear indent style left
-	<li><strong>IRX CLEAR</strong>&nbsp;= quit and clear indent style right
-	<li><strong>IBX CLEAR</strong>&nbsp;= quit and clear indent style both
-</ul>
-<br>
-Indent styles may be combined and manipulated separately.  You could,
-for example, have a left indent of 4 picas and a right indent of 6
-picas and control each separately, as in the following example.
-<p>
-<pre>
-	.IL 4P     \"Indent left 4 picas
-	.IR 6P     \"Indent right 6 picas
-	Some text
-	.IRX       \"Turn off the right indent only
-	More text  \"Text is still indented 4 picas left
-</pre>
-
-If, at <kbd>.IRX</kbd>, you wanted the text afterwards to have no
-indents (either left or right), you would enter <kbd>.IQ</kbd>,
-which exits all indent styles at once.
-<p>
-<strong>A word of advice:</strong> Indents are best used only when
-you have a compelling reason not to change the current left margin or
-line length.  In many instances where indents might seem expedient,
-it's better to use tabs, or actually change the left margin or the
-line length.  <strong>Mom</strong>'s indenting macros are flexible
-and powerful, but easy to get tangled up in.  Personally, I don't
-use them much, except for cutarounds and multi-level lists à la html,
-at which they excel.

-<strong>A word of advice:</strong> If you need to manipulate left and

-<p>
-A temporary indent is one that applies only to the first line of

-The first time you invoke <strong>TI</strong>, you must give it

-<em>*The optional argument requires a <a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a></em>
-

-A hanging indent looks like this:
-<p>
-<pre>
-	The thousand injuries of Fortunato I had borne as best I
-	    could, but when he ventured upon insult, I vowed
-	    revenge.  You who so well know the nature of my soul
-	    will not suppose, however, that I gave utterance to a
-	    threat, at length I would be avenged...
-</pre>
-
-The first line of text &quot;hangs&quot; outside the left
-margin.
-<p>
-In order to use hanging indents, you must first have a left indent
-active (set with either
-<a href="#IL">IL</a>
-or
-<a href="#IB">IB</a>).
-<strong>Mom</strong> will not hang text outside the left margin set with
-<a href="#L_MARGIN">L_MARGIN</a>
-or outside the left margin of a tab.
-<p>
-The first time you invoke <strong>HI</strong>, you must give it
-a measure.  If you want the first line of a paragraph to hang by,
-say, 1 pica, do
-<p>
-<pre>
-	.IL 1P
-	.HI 1P
-</pre>
-
-Subsequent invocations of <strong>HI</strong> do not require you
-to supply a measure; <strong>mom</strong> keeps track of the
-last measure you gave it.
-<p>
-Generally speaking, you should invoke <strong>HI</strong> immediately
-prior to the line you want hung (i.e. without any intervening
-<a href="definitions.html#TERMS_CONTROLLINES">control lines</a>).
-And because hanging indents affect only one line, there's no need to turn
-them off.
-<p>
-<a name="NUM_LISTS"><h3><u>A recipe for numbered lists</u></h3></a>
-<p>
-<strong>PLEASE NOTE: mom</strong> now has macros for setting lists (see
-<a href="docelement.html#LIST_INTRO">Nested lists</a>),
-making this recipe superfluous.  It remains here in the hope that
-it will clarify the use of hanging indents generally, if no longer
-specifically.
-<p>
-Consider the following example:
-<p>
-<pre>
-	.PAGE 8.5i 11i 1i 1i 1i 1i
-	.FAMILY  T
-	.FT      R
-	.PT_SIZE 12
-	.LS      14
-	.JUSTIFY
-	.KERN
-	.SS 0
-	.IL \w'\0\0.'    \"Indent left by 2 figure spaces and a period
-	.HI \w'\0\0.'    \"Hang first line of text back by 2 figure spaces and a period
-	1.\0The most important point to be considered is whether the
-	answer to the meaning of life, the universe, and everything
-	really is 42.  We have no-one's word on the subject except
-	Mr. Adams'.
-	.HI
-	2.\0If the answer to the meaning of life, the universe,
-	and everything is indeed 42, what impact does this have on
-	the politics of representation?  42 is, after all not a
-	prime number.  Are we to infer that prime numbers don't
-	deserve equal rights and equal access in the universe?
-	.HI
-	3.\0If 42 is deemed non-exclusionary, how do we present it
-	as the answer and, at the same time, forestall debate on its
-	exclusionary implications?
-</pre>
-
-First, we invoke a left indent with a measure equal to the width
-of 2
-<a href="definitions.html#TERMS_FIGURESPACE">figures spaces</a>
-plus a period (using the
-<a href="inlines.html#INLINE_STRINGWIDTH_GROFF">\w</a>
-inline escape).  At this point, the left indent is active; text
-afterwards would normally be indented.  However, we invoke a hanging
-indent of exactly the same width, which hangs the first line (and
-first line only!) to the left of the indent by the same distance
-(in this case, that means &quot;out to the left margin&quot;).
-Because we begin the first line with a number, a period, and a
-figure space, the actual text (&quot;The most important point...&quot;)
-starts at exactly the same spot as the indented lines that
-follow.
-<p>
-Notice that subsequent invocations of <strong>HI</strong> without a
-measure produce exactly the same effect.
-<p>
-Paste the example above into a file and preview it with <kbd>groff -mom -X
-&lt;filename&gt;</kbd> to see hanging indents in action.
-<p>
-<strong>IMPORTANT:</strong> Unlike <strong>IL, IR</strong> and
-<strong>IB</strong>, measures given to <strong>HI</strong>
-are NOT additive.  Each time you pass a measure to
-<strong>HI</strong>, the measure is treated literally.

-<h2><a name="USING_INTRO"><u>Introduction</u></a></h2>
-
-As explained in the section
-<a href="intro.html#INTRO">What is mom?</a>,
-<strong>mom</strong> can be used in two ways: for straight typesetting
-or for document processing.  The difference between the two is
-that in straight typesetting, every macro is a literal
-typesetting instruction that determines precisely how text
-following it will look.  Document processing, on the other hand,
-uses markup &quot;tags&quot; (e.g. <kbd>.PP</kbd> for
-paragraphs, <kbd>.HEAD</kbd> for heads, <kbd>.FOOTNOTE</kbd>
-for footnotes, etc.) that make a lot of typesetting decisions
-automatically.
-<p>
-You tell <strong>mom</strong> that you want to use the document
-processing macros with the
-<a href="docprocessing.html#START">START</a>
-macro, explained below.  After <strong>START</strong>,
-<strong>mom</strong> determines the appearance of text following
-the markup tags automatically, although you, the user, can easily
-change how <strong>mom</strong> interprets the tags.  This gives you
-nearly complete control over document design.  In addition, the
-typesetting macros, in combination with document processing, let you
-meet all sorts of typesetting needs that just can't be covered by
-&quot;one macro fits all&quot; markup tags.
-<p>
-<a name="USING_MACROS">
-	<h2><u>How to input mom's macros</u></h2>
-</a>
-
-Regardless of which way you use <strong>mom</strong>, the
-following apply.
-<br>
-<ol>
-	<li>You need a good text editor for inputting
-		<strong>mom</strong> files.
-		<p>
-		I cannot recommend highly enough that you use an
-		editor that lets you write syntax highlighting
-		rules for <strong>mom</strong>'s macros and
-		<a href="definitions.html#TERMS_INLINES">inline escapes</a>.
-		I use the vi clone called elvis, and find it a pure
-		joy in this regard.  Simply colourizing macros and
-		inlines to half-intensity can be enough to make text stand
-		out clearly from formatting commands.
-	<li>All <strong>mom</strong>'s macros begin with a period
-		(dot) and must be entered in upper case (capital)
-		letters.
-	<li>Macro
-		<a href="definitions.html#TERMS_ARGUMENTS">arguments</a>
-		are separated from the macro itself by spaces.  Multiple
-		arguments to the same macro are separated from each
-		other by spaces.  Any number of spaces may be used.  All
-		arguments to a macro must appear on the same line as the
-		macro.
-	<li>Any argument (except a
-		<a href="definitions.html#TERMS_STRINGARGUMENT">string argument</a>)
-		that is not a digit must be entered in upper case
-		(capital) letters.
-	<li>Any argument that requires a plus or minus sign must
-		have the plus or minus sign prepended to the argument
-		with no intervening space (e.g. +2, -4).
-	<li>Any argument that requires a
-		<a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>
-		must have the unit appended directly to the argument,
-		with no intervening space (e.g. 4P, .5i, 2v).
-	<li><a href="definitions.html#TERMS_STRINGARGUMENT">String arguments</a>,
-		in the sense that the term is used in this manual, must
-		be surrounded by double-quotes (&quot;text of
-		string&quot;).  Multiple string arguments are separated
-		from each other by spaces (each argument surrounded by
-		double-quotes, of course).
-	<li>If a string argument, as entered in your text editor,
-		becomes uncomfortably long (i.e. runs longer than the
-		visible portion of your screen or window), you may break
-		it into two or more lines by placing the backslash
-		character (<kbd>\</kbd>) at the ends of lines to break
-		them up, like this:
-	<p>
-	<pre>
-	.SUBTITLE "An In-Depth Consideration of the \
-	Implications of Forty-Two as the Meaning of Life, \
-	The Universe, and Everything"
-	</pre>
-</ol>
-
-It's important that formatted documents be easy to read/interpret
-when you're looking at them in a text editor.  One way to achieve
-this is to group macros that serve a similar purpose together, and
-separate them from other groups of macros with a blank comment line.
-In groff, that's done with <kbd>\#</kbd> on a line by itself.
-Consider the following, which is a template for starting the
-chapter of a book.
-<p>
-<pre>
-	.TITLE   "My Pulitzer Novel"
-	.AUTHOR  "Joe Blow"
-	.CHAPTER  1
-	\#

-	.PRINTSTYLE TYPESET

-	<h2><u>Printing -- invoking groff with mom</u></h2>
-</a>
-
-After you've finished your document, naturally you will want to
-print it.  This involves invoking groff from the command line.
-In all likelihood, you already know how to do this, but in case
-you don't, here are two common ways to do it.
-<p>
-<pre>
-	groff -mom -l &lt;filename&gt;
-	groff -mom &lt;filename&gt; | lpr
-</pre>
-
-In the first, the <strong>-l</strong> option to groff tells
-groff to send the output to your printer.  In the second, you're
-doing the same thing, except you're telling groff to pipe the
-output to your printer.  Basically, they're the same thing.  The
-only advantage to the second is that your system may be set up
-to use something other than <strong>lpr</strong> as your print
-command, in which case, you can replace <strong>lpr</strong>
-with whatever is appropriate to your box.
-<p>
-Sadly, it is well beyond the scope of this manual to tell you
-how to set up a printing system.  See the README file for
-minimum requirements to run groff with <strong>mom</strong>.
-<p>
-<strong>NOTE FOR ADVANCED USERS:</strong> I've sporadically had groff
-choke on perfectly innocent sourced files within <strong>mom</strong>
-documents.  You'll know you have this problem when groff complains that
-it can't find the sourced file even when you can plainly see that the
-file exists, and that you've given <code>.so</code> the right path and
-name.  Should this happen, pass groff the <code>-U</code> (unsafe mode)
-option along with the other options you require.  Theoretically, you
-only need <code>-U</code> with <code>.open, .opena, .pso, .sy,</code>
-and <code>.pi</code>, however reality seems, at times, to dictate
-otherwise.
-<p>
-<a name="USING_PREVIEWING">
-	<h2><u>How to preview documents</u></h2>
-</a>
-
-Other than printing out hard copy, there are two well-established
-methods for previewing your work.  Both assume you have a working
-X server.
-<p>
-Groff itself comes with a quick and dirty previewer called
-gxditview. Invoke it with
-<p>
-<pre>
-	groff -X -mom filename
-</pre>
-
-It's not particularly pretty, doesn't have many navigation
-options, requires a lot of work if you want to use other than
-the &quot;standard&quot; groff PostScript fonts, and occasionally
-has difficulty accurately reproducing some of
-<strong>mom</strong>'s macro effects
-(<a href="goodies.html#SMARTQUOTES">smartquotes</a>
-and
-<a href="goodies.html#LEADER">leaders</a>
-come to mind).  What it does have going for it is that it's fast and
-doesn't gobble up system resources.
-<p>
-A surer way to preview documents is with <strong>gv</strong>
-(ghostview).  This involves processing documents with groff,
-and directing the output to a PostScript file, like this,
-<p>
-<pre>
-	groff -mom filename &gt; filename.ps
-</pre>
-then opening .ps file in <strong>gv</strong>.
-<p>
-While that may sound like a lot of work, I've set up my editor
-(elvis) to do it for me.  Whenever I'm working on a document that
-needs previewing/checking, I fire up <strong>gv</strong> with the
-&quot;Watch File&quot; option turned on.  To look at the file, I
-tell elvis to process it (with groff) and send it to a temporary
-file (<kbd>groff -mom filename &gt; filename.ps</kbd>), then open
-the file inside <strong>gv</strong>.  Ever after, when I want to
-look at any changes I make, I simply tell elvis to work his magic
-again.  The Watch File option in <strong>gv</strong> registers that
-the file has changed, and automatically loads the new version.
-Voilà! --instant previewing.

-Antoine de St-Exupéry asserted that elegance in engineering is
-achieved not when there is nothing left to add, but when there is
-nothing left to take away.
-
-By those standards, mom is a Rube Goldberg contraption.  She was
-created over the years while groff, and my understanding of it,
-changed and evolved.  However, I'm a firm believer in "if it
-ain't broke, don't fix it," so I'm leaving any major clean-up
-of redundancies and whatnot for a rainy day.
-
-Inasmuch as possible, macros that turn a feature on or off follow
-a similar style.  Invoking the macro without an argument turns
-the feature on.  Invoking it with any other argument turns it off.
-Use of the argument OFF is recommended, but not required; users
-may find other conventions preferable (e.g. NO, X, END, QUIT, etc.).
-
-"<anything>" in the description of arguments that can be passed
-to a macro means that any argument turns the feature off.

-About the warn level
---------------------
-
-There's a lot of testing for the presence of number registers and
-strings in this macro file.  Many of the registers and strings
-pop into and out of existence on the fly.  For convenience, I
-often use
-
-    .if \\n[whatever]    and    .if !\\n[whatever]
-
-to test "if the register exists and is (not) empty."  Groff,
-encountering such tests when called with the -ww options, emits
-
-    warning: number register whatever not defined.
-
-Groff also warns about strings similarly tested for.
-
-The warn level, above, is high in order to shut off those
-warnings.  If you're futzing in this file and need more verbose
-warnings, either comment out ".warn 8192" or set the warnlevel
-to the one you need (but be ready for lots of what I've just
-described).

-INLINE KERNING AND HORIZONTAL MOVEMENT
---------------------------------------
-Kerning
-
-Inline kerning provides a simple method for users to adjust the
-amount of space between any two letters.  It's predicated on a
-unit of measure "U", which is 1/36 of the current point size as
-returned by \n[.ps].  E.g., if the current point size is 18,
-\n[.ps] returns 18000u, therefore U=500u.  Since U remains
-proportional relative to the current point size, the amount
-of kerning between two letters as expressed in Us remains
-visually similar regardless of changes in point size.
-
-N.B.--the amount of inline kerning supplied by \*[BU<n>] or
-\*[FU<n>] is added to or subtracted from any kerning that already
-takes place between two characters when automatic kerning is
-turned on.
-
-In groff v. 1.17.2, it was not possible to pass arguments to macros that
-were called with inline escapes, nor thence to evaluate conditional
-expressions.  Consequently, each pseudo-escape \[BU<n>] had to be defined
-separately with ".char".
-
-As of v. 1.18, one can pass arguments to inline strings/macros,
-hence it is now possible to do \*[BU n] where n, inline, is the desired
-number of kern units.  The original .char definitions have been left in
-for backward compatibility with documents created prior to mom-1.1.3c.

-\# WHOLE LINE KERNING (RW and EW)
-\# -----------------------------
-\#
-.ig
-The line kerning macros are special instances of track kerning,
-used where a complete line needs to be tightened (or relaxed) in
-order to accomodate or remove one or two more characters
-than the default justification permits.
-..
-\#
-\# *Argument:
-\#   <amount of overall "kerning" (letter spacing) to apply to the line>
-\# *Function:
-\#   Invokes .tkf (track kerning) for the current font with
-\#   1 as both the upper and lower point size limits, so that
-\#   the value entered by the user applies regardless of point
-\#   size.  RW ("Reduce Whitespace") reduces the amount of space
-\#   between all characters by an equal amount.  EW ("Extra
-\#   Whitespace") increases the amount of space.
-\# *Notes:
-\#   Decimal values are acceptable.
-\#
-.ig
-The groff documentation is a tad confusing about what unit of
-measure is used in track kerning, only that the width of each
-character is increased or decreased by the amount(s) passed as
-arguments to .tkf, and something about linear function of point
-size.  In fact, with the way I've put this macro together, it
-doesn't matter.  All the user needs to know is that a value of
-one will produce an unacceptably tight or loose line at most text
-point sizes; therefore, effective use of RW and EW is in the
-fractional range below 1 (e.g. .25, .5).  Given that RW and EW
-are for massaging type, a certain amount of experimentation and
-previewing is expected and necessary.
-
-\n(.f holds the current font number, which is acceptable to .tkf.
-
-RW and EW must be reset to 0 to cancel their effect on subsequent
-output lines.

-\# +++TABS+++

-.ig
-There are two different kinds of tabs available: typesetting tabs
-and string tabs.
-
-Typesetting tabs are set with TAB_SET, which requires a tab number,
-an indent (offset) from the left margin and a length (optionally
-with a quad direction and an instruction to fill lines).  After tabs
-are set with TAB_SET, they are called with .TAB n, where "n"
-corresponds to the number passed to TAB_SET as a valid tab number.
-
-String tabs allow the user to mark off tab positions inline.  Tab
-indents and lengths are calculated from the beginning and end
-positions of the marks.  Up to 19 string tabs may be created,
-numbered 1-19.  Once created, they are called with .TAB n,
-just like typesetting tabs.
-
-Setting up string tabs is a two-step procedure.  First, the user
-enters an input line in which s/he wants to mark off string tabs.
-The beginning of a tab is marked with \*[STn], where "n" is
-the desired number of the tab.  The end of the the tab is marked
-with \*[STnX].  All ST's must have a matching STX.  String tabs
-may be nested.
-
-Next, the user invokes .ST n for every string tab defined, and
-optionally passes quad information to it.  That done, string tabs
-can be called just like typesetting tabs.
-
-String tabs don't preview properly with gxditview.  Use gv instead.

-\# *Function:
-\#   Creates macros TABn and TAB n, where "n" is any arbitrary number.
-\#   TABn is a typesetting tab (i.e. a tab defined as an indent
-\#   from the page left offset plus a line length.)
-\# *Notes:
-\#   n      = arbitrary digit to identify the tab
-\#   indent = indent from left margin; unit of measure required

-\#   LRCJ   = quad for tab (left, right, center, justified)
-\#            If option QUAD afterwards is not given, quad is line for line
-\#            (no fill mode), meaning that there's no need for .BR or .br
-\#            between lines.
-\#   QUAD   = fill tab (so it behaves as if .QUAD LRC or .JUSTIFY
-\#            had been given).

-Examples:
---------
-
-.TAB_SET 1 2P+6p 12P C
-
-means "create a tab numbered 1 that starts 2 picas and 6 points from
-the left margin, is 12 picas long, and centre each input line."
-
-.TAB_SET 1 2P+6P 12P C QUAD
-
-means exactly the same thing, except that input lines are joined and
-the area delimted by the tab filled with centered text.
-
-TAB n can be called at any time after being set.
-
-Tabs are NOT columnar in behaviour.  If the text inside a
-tab runs to several lines, when you call the next tab a break
-occurs, meaning that the new tab starts one line below the last
-line in the previous tab.  For columnar behaviour, you must
-use the multi-column macros in addition to tabs.
-
-If you want tabs to line up bottom-line to bottom-line (most likely
-single line tabs), use .TN (provided the tabs are numbered sequentially).

-
-If you want to reset tabs, you must use .TQ before .TAB_SET.

-\# +++INDENTS+++
-\#
-.ig
-There are five styles of indents: left, right, both, temporary,
-and hanging.  Each is set/invoked with a different macro.
-Indent macros begin with the letter "I", hence .IL means "indent left,"
-.IR means "indent right," and so on.
-
-The first time any of the indent macros is used, it requires an
-argument--the size of the indent (with a unit of measure).  The
-size may also be entered using the \w escape--very useful
-for numbered lists using HI.  The unit of measure is required.
-Subsequent invocations don't require the argument; the indent
-measure remains the same until it's changed by invoking the macro
-with an argument again.
-
-If no indents are in effect, the arguments passed to indent macros are
-measured from the left and right margins of the page.  If a left indent
-or a right indent is already in effect, the arguments passed to
-the indent macros are calculated from the current values; in other words,
-the arguments are additive.  If you quit an indent and later return
-to it, its value will be the value last in effect, unless you pass
-it an argument.  If you do pass an argument, it is added to the last
-value in effect, unless you cleared the indent with one of
-.I<LRB>X/Q macros.
-
-Example
--------
-
-.IL 2P
-...some text...
-.IL 2P
-...some text...
-.IQ
-...some text...
-.IL
-...some text...
-
-The first .IL 2P indents text 2P from the left margin.  The second
-.IL 2P indents text by an additional 2P, i.e. 4P from the left margin.
-.IQ turns the indent off.  The last .IL (which has no argument)
-takes its value from the total of all arguments passed to .IL (in
-this case, 2P and 2P), therefore it indents 2P+2P from the left
-margin, i.e. 4P.  If you wanted the last .IL to indent just 2P,
-you'd either have to reset the .IL prior to .IQ (.IL -2P), or pass
-the last .IL the argument 2P.
-
-To reverse the sense of an indent added to an indent, you may use
-negative values.
-
-Indents can be turned off individually with ILX, IRX, and IBX.
-LEFT and RIGHT indents may be combined and manipulated
-separately, (e.g. you can have an IL of 2P and an IR of 4P
-operative at the same time, and then change, say, the IL to
-4P--thereby left indenting 6P--while the IR remains at 4P.
-
-IB automatically turns off IL and IR.  They have to be reinvoked
-again when needed. IL and IR automatically turn IB off; it, too,
-has to be reinvoked with needed.
-
-All indents can be turned off at once with IQ.  The ILX, IRX, IBX,
-and IQ macros simply turn the indents off; the values stored in
-the respective indent macros (IL, IR, IB) remain in effect.  If
-the user wishes to clear the values, the I<LRB>X macros should be
-invoked with the single argument CLEAR.  IQ CLEAR clears out
-the values stored for all indent styles.
-
-Indents *must* be turned off before settting string tabs
-inside PAD.  Generally, in order not to get confused, it's a
-good idea to turn all indents off before setting any tabs.
-
-TI and HI are special cases.  There's no need to turn them off,
-since they affect only one line--the first after their
-invocation.  Like the other indent styles, the first time
-they're invoked, they require a value in iPpcm; each subsequent
-invocation without an argument will use the same value.  To
-change the value, simply pass a new value.  Values for TI and HI
-are *not* additive.
-
-HI presupposes that you already have a left or both indent on.
-HI will never hang a line outside the left margin of a document
-or column.  In other words, you must have IL or IB on before you
-can use HI.

-\# THE START MACRO
-\# ---------------
-\# *Arguments:
-\#   <none>
-\# *Function:
-\#   Reads in default document style parameters and any parameter
-\#   the user has changed before issuing START.
-\#   Using the information gathered in the opening macros,
-\#   prints appropriate title (or chapter #), subtitle, author
-\#   and document type (if appropriate).
-\# *Notes:
-\#   The .PRINT \& (zero-width character) is required to get the
-\#   subsequent .sp request to work as advertised.
-\#
-\#   The overall document line length, family, and point-size
-\#   are stored in #DOC_L_LENGTH, $DOC_FAM, and #DOC_PT_SIZE for
-\#   use in the HEADER and FOOTER macros.
-\#

-\#   In order to convert the title string to caps in the header (in the

-\#   quad left, quad centre, and quad right to arrange the three bits
-\#   of the header, rather than .tl.  This allows the use of the CAPS macro.
-\#   The downside is that I have to add \\v'-(\\n[#LEAD]u*<n>) in order
-\#   for -Tlatin1 output to align the header/footer strings on the baseline.
-\#   The console output still isn't brilliant, but at least it's

-\# *Arguments:
-\#   <none> | <anything>
-\# *Function:
-\#   Indents quoted text in fill mode and shortens line length
-\#   equivalently, or turns BLOCKQUOTE off.
-\# *Notes:
-\#   Owing to the need to bottom align TYPESET pages, quoted text gets
-\#   diverted so its depth can be measured (in DO_QUOTE) for determining
-\#   how much space to put before and after.
-\#
-\#   .PP after blockquote is optional if there's only one para,
-\#   but REQUIRED if there's more than one.

-\#   (viz. an extra line space).  TYPESET puts in only half

-\#   fits on the the page; otherwise it puts in a full extra blank

-Mom treats bibliographies and endnotes very similarly.  The chief
-difference is that endnotes are collected and formatted inside a
-diversion, while bibliographies are built "by hand."  ENDNOTES sets
-up the endnotes page and outputs the formatted diversion.
-BIBLIOGRAPHY sets up the bibliography page, then awaits refer
-commands.
-
-All of the bibliography control macros have their exact
-counterparts in the endnotes control macros.  It was tempting to do
-fancy stuff with aliases to avoid the repetition, but for reasons
-of my own sanity, and for the benefit of anyone wanting to play
-around with the bibliography control macros, I decided to keep them
-separate.
-
-Because the bibliography control macros all have endnotes
-equivalents, refer to the appropriate, similar endnote macro for
-Arguments, Function and Notes.

-two spaces after each period.  The spaces are hardwired into the

-README for pdfmark.tmac
-=======================
-
-Copyright (C) 2004, Free Software Foundation Inc.
-Contributed by Keith Marshall (keith.d.marshall@ntlworld.com)
-
-This is free software.  See file COPYING, for copying permissions,
-and warranty disclaimer.
-
-This is a preview release of a proposed pdfmark.tmac macro package,
-for use with GNU troff (groff).  It is not yet complete, and should
-be considered as an alpha release;  there are a few problems to be
-resolved (see file PROBLEMS).
-
-Partial documentation is provided, in groff-ms format.  To convert
-this to PDF format, you will require a working groff installation,
-a working ghostscript installation, with the gs command in your PATH,
-and a GNU-compatible make.  The tarball should be unpacked in the
-top directory of your groff source tree, then:
-
-  cd <groff-current>/contrib/pdfmark
-  make pdfmark
-
-where <groff-current> is the top directory of your current groff
-source tree.
-
-Included in this package, are:
-
-  pdfmark.tmac -- the core pdfmark macro set
-  spdf.tmac    -- a rudimentary set of bindings for ms macros
-  pdfmark.ms   -- preliminary documentation
-  cover.ms     -- a template for the documentation cover sheet
-  gnu.eps      -- the groff logo, copied from the groff distribution
-  Makefile     -- makefile, for formatting the documentation
-  README       -- this file
-  PROBLEMS     -- a list of known problems
-  TODO         -- a list of planned features, not yet implemented
-
-To make the pdfmark macros generally usable, copy pdfmark.tmac to the
-'site-tmac' directory appropriate to your groff installation; (ms users
-may also wish to copy spdf.tmac).  The macros may then be accessed, by
-including the '-mpdfmark' option on the groff command line; (for ms
-users, '-mspdf' is equivalent to '-ms -mpdfmark', with some extra
-macros 'thrown in').
-
-Comments, and bug reports are welcomed.  Please post to the groff
-mailing list, groff@gnu.org; (you must be subscribed to this list to
-post mails).  To subscribe, visit
-  
-  http://lists.gnu.org/mailman/listinfo/groff

-TODO items for pdfmark.tmac
-===========================
-
-Add copyright information to PDF documentation.
-
---------
-
-Add acknowledgements and trade mark ownership notifications
-to PDF documentation.
-
---------
-
-Provide documentation in man page and texinfo formats.
-
---------
-
-Add comments in spdf.tmac, to clarify its operation.
-Also add commentary in pdfmark.tmac, to clarify operation of
-recent changes.
-
---------
-
-Make Makefile generic, so 'configure' can resolve target
-system dependencies.
-
-* Comment added 2005-02-26 by Keith Marshall <keith.d.marshall@ntlworld.com>
-
-If this refers to contrib/pdfmark/Makefile, then it is addressed by the new
-`pdfroff' script; the original Makefile may be considered redundant.  Local
-system dependencies are resolved by `configure', and applied to `pdfroff',
-when it is generated from `pdfroff.sh'.
-
---------
-
-Improve Makefile.sub, to integrate pdfmark.tmac installation
-into a regular groff build.  Add it to groff's Makefile.in.
-
-* Comment added 2005-02-26 by Keith Marshall <keith.d.marshall@ntlworld.com>
-
-Completed.
-
---------
-
-Provide a `pdfmark' script (or call it `groff2pdf'?) which
-actually converts a groff input file to pdf, and which
-takes care of the necessary intermediate steps to handle
-PDF marks.
-
-* Comment added 2005-02-26 by Keith Marshall <keith.d.marshall@ntlworld.com>
-
-This facility now provided by `pdfroff' script; documented in `pdfroff.man'.
-Man page still requires an additional section, to describe use of `stylesheet'
-feature.  Script also requires documentation in PDF and texinfo formats.

-It might appear that it is a fairly simple matter to
-produce documents in Adobe\*(rg\~\(lqPortable\~Document\~Format\(rq,
-commonly known as PDF, using
-.CW groff ) GNU\~Troff\~(
-as the document formatter.
-Indeed,
-.CW groff 's
-default output format is the native Adobe\*(rg\~PostScript\*(rg format,
-which PDF producers such as Adobe\*(rg Acrobat\*(rg Distiller\*(rg,
-or GhostScript, expect as their input format.
-Thus, the PDF production process would seem to entail simply
-formatting the document source with
-.CW groff ,
-to produce a PostScript\*(rg version of the document,
-which can subsequently be processed by Acrobat\*(rg Distiller\*(rg
-or GhostScript, to generate the final PDF document.
-.LP
-For many PDF production requirements,
-the production cycle described above may be sufficient.
-However, this is a limited PDF production method,
-in which the resultant PDF document represents no more than
-an on screen image of the printed form of the document, if
-.CW groff 's
-PostScript\*(rg output were printed directly.
-.LP
-The Portable Document Format provides a number of features,
-which significantly enhance the experience of reading a document on screen,
-but which are of little or no value to a document which is merely printed.
-It
-.EM is
-possible to exploit these PDF features, which are described in the Adobe\*(rg
-.\"
-.de pdfmark-manual

-has been provided.
-Thus, to incorporate PDF features in a document,
-the appropriate macro calls, as described below, may be placed in the

-.CW groff
-command of the form
-.QP
-.fam C
-groff -Tps [-m
-.I name "] -m"

-.I options \& [-
-.I "file ..." \& "...] "
-.LP
-It may be noted that the
-.CW pdfmark
-macros have no dependencies on, and no known conflicts with,
-any other
-.CW groff
-macro package;  thus, users are free to use any other macro package,
-of their choice, to format their documents, while also using the
-.CW pdfmark
-macros to add PDF features.
-.NH 2
-.XN -N pdfmark-operator -- The \F[C]pdfmark\F[] Operator
-.LP
-All PDF features are implemented by embedding instances of the
-.B \F[C]pdfmark\F[]
-operator, as described in the Adobe\*(rg
-.pdfmark-manual ,
-into
-.CW groff 's
-PostScript\*(rg output stream.
-To facilitate the use of this operator, the
-.CW pdfmark

-.CW pdfmark
-macro; it simply emits its argument list,
-as arguments to a
-.CW pdfmark
-operator, in the PostScript\*(rg output stream.
-.LP
-.pdfhref M -N pdfmark-example

-.XN -N docview -- Selecting an Initial Document View
-.LP
-By default,
-when a PDF document is opened,
-the first page will be displayed,
-at the default magnification set for the reader,
-and outline and thumbnail views will be hidden.
-When using a PDF reader,
-such as Acrobat\*(rg\~Reader,
-which supports the
-.CW /DOCVIEW
-class of the
-.CW pdfmark
-operator,
-these default initial view settings may be overridden,
-using the
-.CW pdfview
-macro.
-For example
-.QP
-.CW ".pdfview /PageMode /UseOutlines"
-.LP
-will cause Acrobat\*(rg\~Reader to open the document outline view,
-to the left of the normal page view,
-while
-.QP
-.CW ".pdfview /PageMode /UseThumbs"
-.LP
-will open the thumbnail view instead.
-.LP
-Note that the two
-.CW /PageMode

-To do this, we use the

-.DE
-Notice that the
-.CW pdfinfo

-In each case, the first argument is the name of the applicable
-.CW /DOCINFO
-key, which
-.EM must
-be named with an initial solidus character;

-.XR docview ), (
-the
-.CW /DOCINFO

-.CW pdfsync
-macro,

-.NH 2
-.XN -N add-outline -- Creating a Document Outline
-.LP
-A PDF document outline comprises a table of references,
-to \(lqbookmarked\(rq locations within the document.
-When the document is viewed in an \(lqoutline\~aware\(rq PDF document reader,
-such as Adobe\*(rg Acrobat\*(rg Reader,
-this table of \(lqbookmarks\(rq may be displayed in a document outline pane,
-or \(lqBookmarks\(rq pane, to the left of the main document view.
-Individual references in the outline view may then be selected,
-by clicking with the mouse,
-to jump directly to the associated marked location in the document view.
-.LP
-The document outline may be considered as a collection of \(lqhypertext\(rq
-references to \(lqbookmarked\(rq locations within the document.
-The
-.CW pdfmark
-macro package provides a single generalised macro,
-.CW pdfhref ,
-for creating and linking to \(lqhypertext\(rq reference marks.
-This macro will be described more comprehensively in a later section,
-.XR pdfhref ); (
-the description here is restricted to its use for defining document outline entries.
-.NH 3
-.XN -N basic-outline -- A Basic Document Outline
-.LP
-In its most basic form, the document outline comprises a structured list of headings,
-each associated with a marked location, or \(lqbookmark\(rq, in the document text,
-and a specification for how that marked location should be displayed,
-when this bookmark is selected.
-.LP
-To create a PDF bookmark, the

-at the point in the document where the bookmark is to be placed,
-in the form
-.QP
-.fam C
-.B ".pdfhref O"
-.I level > <
-.I "descriptive text ..."
-.LP
-in which the reference class
-.CWB O \& \& \(rq \(lq
-stipulates that this is an outline reference.
-.LP
-Alternatively, for those users who may prefer to think of a document outline
-simply as a collection of bookmarks, the
-.CW pdfbookmark
-macro is also provided \(em indeed,
-.CW pdfhref
-invokes it, when processing the

-reference class operator.
-It may be invoked directly, in the form
-.QP
-.fam C
-.B .pdfbookmark
-.I level > <
-.I "descriptive text ..."
-.LP
-Irrespective of which of the above macro forms is employed, the
-.CWI level > <
-argument is required.
-It is a numeric argument, defining the nesting level of the \(lqbookmark\(rq
-in the outline hierarchy, with one being the topmost level.
-Its function may be considered analagous to the
-.EM "heading level"
-of the document's section headings,
-for example, as specified with the
-.CW NH
-macro, if using the
-.CW ms
-macros to format the document.
-.LP
-All further arguments, following the
-.CWI level > <
-argument, are collected together, to specify the heading text which will appear
-in the document's outline view.
-Thus, the outline entry for this section of this document,
-which has a level three heading,
-might be specified as
-.QP
-.CW

-at the next inner level of the outline hierarchy;
-typically however,
-these subordinate entries will be defined
-.EM later
-in the document source, and the appropriate
-.CW /Count
-value will be unknown, when defining the parent entry.
-.LP
-To resolve this paradox, the
-.CW pdfhref
-macro creates the outline entry in two distinct phases \(em
-a destination marker is placed in the PostScript\*(rg output stream immediately,

-Effectively, to ensure integrity of the document outline structure,
-this means that each top level outline entry, and

-.LP
-One potential problem, which arises from the use of the \(lqoutline cache\(rq,

-is established at the time when the outline entry is created.
-However, rather than requiring that each individual use of the

-should include its own view specification,
-the actual specification assigned to each entry is derived from
-a generalised specification defined in the string
-.CW PDFBOOKMARK.VIEW ,
-together with the setting of the numeric register
-.CW PDFHREF.VIEW.LEADING ,
-which determine the effective view specification as follows:\(en

-.XN -N outline-folding -- Folding the Outline to Conceal Less Significant Headings
-.LP
-When a document incorporates many subheadings,
-at deeply nested levels,
-it may be desirable to \(lqfold\(rq the outline
-such that only the major heading levels are initially visible,
-yet making the inferior subheadings accessible,
-by allowing the reader to expand the view of any heading branch on demand.
-.LP
-The
-.CW pdfmark

-through the setting of the

-register.
-This register should be set to the number of heading levels
-which it is desired to show in expanded form, in the
-.EM initial
-document outline display;
-all subheadings at deeper levels will still be added to the outline,

-\&.\e" with additional subordinate level headings folded.
-\&.\e"
-\&.nr PDFOUTLINE.FOLDLEVEL 3
-.DE
-.QE
-.LP
-results in only the first three levels of headings being displayed
-in the document outline,
-.EM until
-the reader chooses to expand the view,
-and so reveal the lower level headings in any outline branch.
-.LP
-The initial default setting of
-.CW PDFOUTLINE.FOLDLEVEL ,
-if the document author does not choose to change it,
-is 10,000.
-This is orders of magnitude greater than the maximum heading level
-which is likely to be used in any document;
-thus the default behaviour will be to show document outlines fully expanded,
-to display all headings defined,
-at all levels within each document.
-.LP
-The setting of
-.CW PDFOUTLINE.FOLDLEVEL
-may be changed at any time;
-however, the effect of each such change may be difficult to predict,
-since it is applied not only to outline entries which are defined
-.EM after

-.XN -N multipart-outline -- Outlines for Multipart Documents
-.LP
-When a document outline is created, using the
-.CW pdfhref
-macro, each reference mark is automatically assigned a name,
-composed of a fixed stem followed by a serially generated numeric qualifier.
-This ensures that, for each single part document, every outline reference
-has a uniquely named destination.
-.LP
-As the overall size of the PDF document increases,
-it may become convenient to divide it into smaller,
-individually formatted PostScript\*(rg components,
-which are then assembled, in the appropriate order,
-to create a composite PDF document.
-While this strategy may simplify the overall process of creating and
-editing larger documents, it does introduce a problem in creating
-an overall document outline,
-since each individual PostScript\*(rg component will be assigned
-duplicated sequences of \(lqbookmark\(rq names,
-with each name ultimately referring to multiple locations in the composite document.
-To avoid such reference naming conflicts, the
-.CW pdfhref
-macro allows the user to specify a \(lqtag\(rq,
-which is appended to the automatically generated \(lqbookmark\(rq name;
-this may be used as a discriminating mark, to distinguish otherwise
-similarly named destinations, in different sections of the composite document.
-.LP
-To create a \(lqtagged\(rq document outline,
-the syntax for invocation of the
-.CW pdfhref

-.LP
-Since the most common use of a document outline

-package, to be described later,
-.XR using-spdf ). (
-.LP
-When such an approach is adopted,
-the user will rarely, if ever, invoke the
-.CW pdfhref
-macro directly, to create a document outline.
-For example, the structure and content of the outline for this document
-has been exclusively defined, using a combination of the
-.CW NH
-macro, from the
-.CW ms
-package, to establish the structure, and the
-.CW XN
-macro from
-.CW spdf.tmac ,
-to define the content.
-In this case,

-These options assign their arguments to the

-Other than the use of these additional options,

-.NH 3
-.XN -N add-weblink -- Linking to Internet Resources
-.LP
-In addition to supporting the creation of cross references

-.EM any
-resource which may be specified by a Uniform Resource Identifier,
-(which is usually abbreviated to the acronym \(lqURI\(rq,
-and sometimes also referred to as a Uniform Resource Locator,

-.NH 3
-.XN -N set-format -- Establishing a Format for References
-.LP
-There are two principal aspects to be addressed,
-when defining the format to be used when displaying references.
-Firstly, it is desirable to provide a visual cue,
-to indicate that the text describing the reference is imbued
-with special properties \(em it is dynamically linked to the reference
-destination \(em and secondly, the textual content should
-describe where the link leads, and ideally,
-it should also describe the content of the reference destination.
-.LP
-The visual cue,
-that a text region defines a dynamically linked reference,
-is most commonly provided by printing the text within the active
-region in a distinctive colour.
-This technique will be employed automatically by the
-.CW pdfhref
-macro \(em
-.XR set-colour
-\(em unless the user specifically chooses to adopt, and implement,
-some alternative strategy.
-.NH 4
-.XN -N set-colour -- Using Colour to Demarcate Link Regions
-.LP
-Typically, when a PDF document contains
-.EM active
-references to other locations, either within the same document,
-or even in other documents, or on the World Wide Web,
-it is usually desirable to make the regions
-where these active links are placed stand out from the surrounding text.
-.NH 4
-.XN -N user-format -- Specifying Reference Text Explicitly
-.NH 4
-.XN -N auto-format -- Using Automatically Formatted Reference Text
-.NH 4
-.XN -N custom-format -- Customising Automatically Formatted Reference Text
-.LP
-It is incumbent on the user,
-if employing automatic formatting of the displayed reference,
-.XR set-format ), (
-to ensure that an appropriate reference definition
-is created for the reference destination,
-and is included in the reference map for the document
-in which the reference will appear;
-thus, it may be easiest to
-.EM always
-use manual formatting for external references.
-.NH 3
-.XN Problematic Links
-.LP
-Irrespective of whether a
-.CW pdfhref
-reference is placed using the
-.CWB L \& \& \(rq \(lq
-operator, or the
-.CWB W \& \& \(rq \(lq
-operator, there may be occasions when the resulting link
-does function as expected.
-A number of scenarios, which are known to be troublesome,
-are described below.
-.NH 4
-.XN -N page-trap -- Links with a Page Transition in the Active Region
-.LP
-When a link is placed near the bottom of a page,
-it is possible that its active region, or \(lqhot\(hyspot\(rq,
-may extend on to the next page.
-In this situation, a page trap macro is required
-to intercept the page transition, and to restart the mapping of
-the \(lqhot\(hyspot\(rq boundary on the new page.
-.LP
-The
-.CW pdfmark
-macro package includes a suitable page trap macro, to satisfy this requirement.
-However, to avoid pre\(hyempting any other requirement the user may have for
-a page transition trap, this is
-.EM not
-installed as an active page trap,
-unless explicitly requested by the user.
-.LP
-To enable proper handling of page transitions,
-which occur within the active regions of reference links,
-the user should:\(en
-.QS
-.nr ITEM 0 1
-.IP \n+[ITEM].
-Define a page transition macro, to provide whatever features may be required,
-when a page transition occurs \(em e.g.\& printing footnotes,
-adding page footers and headers, etc.
-This macro should end by setting the output position at the correct
-vertical page offset, where the printing of running text is to restart,
-following the page transition.
-.IP \n+[ITEM].
-Plant a trap to invoke this macro, at the appropriate vertical position
-marking the end of normal running text on each page.
-.KS
-.IP \n+[ITEM].
-Initialise the
-.CW pdfhref
-hook into this page transition trap, by invoking
-.RS
-.IP
-.fam C
-.B "pdfhref I -PT"
-.BI macro-name > <
-.LP
-where
-.CWBI macro-name > <
-is the name of the user supplied page trap macro,
-to ensure that
-.CW pdfhref
-will correctly restart mapping of active link regions,
-at the start of each new page.
-.KE
-.RE
-.QE
-.LP
-It may be observed that this initialisation of the
-.CW pdfhref
-page transition hook is, typically, required only once
-.EM before
-document formatting begins.
-Users of document formatting macro packages may reasonably expect that
-this initialisation should be performed by the macro package itself.
-Thus, writers of such macro packages which include
-.CW pdfmark
-bindings, should provide appropriate initialisation,
-so relieving the end user of this responsibility.
-The following example, abstracted from the sample
-.CW ms
-binding package,
-.CW spdf.tmac ,
-illustrates how this may be accomplished:\(en

-\(lqmeta\(hydata\(rq,

-.LP
-To allow the user to choose when cached
-.CW pdfmark
-data is to be flushed to the output stream, the
-.CW pdfmark

-.CW pdfsync
-macro, (to synchronise the cache and output states).
-In its simplest form, it is invoked without arguments, i.e.
-.QP

-.CW pdfview

-data,
-.EM and 
-the \(lqoutline cache\(rq,
-containing any previously uncommitted document outline data,
-are flushed; ideally, this should be included in a
-.CW groff
-\(lqend macro\(rq, to ensure that
-.EM both
-caches are flushed, before
-.CW groff
-terminates.
-.LP
-Occasionally,
-it may be desirable to flush either the \(lqmeta\(hydata cache\(rq,
-without affecting the \(lqoutline cache\(rq, or vice\(hyversa,
-at a user specified time, prior to reaching the end of the document.
-This may be accomplished, by invoking the
-.CW pdfsync
-macro with an argument, i.e.
-.QP
-.fam C
-.B ".pdfsync M"
-.LP
-to flush only the \(lqmeta\(hydata cache\(rq, or
-.QP
-.fam C
-.B ".pdfsync O"
-.LP
-to flush only the \(lqoutline cache\(rq.
-.LP
-The \(lqmeta\(hydata cache\(rq can normally be safely flushed
-in this manner, at any time
-.EM after

-(it may cause formatting problems,
-most notably the appearance of unwanted white space, if flushed earlier,
-or indeed, if flushed immediately after a page transition,
-but before the output of the content on the new page has commenced).
-Caution is required, however, when explicitly flushing the
-\(lqoutline cache\(rq, since if the outline is to be
-subsequently extended, then the first outline entry after flushing
-.EM must
-be specified at level 1.
-Nevertheless, such explict flushing may occasionally be necessary;

-.
-.SH DESCRIPTION
-.B pdfroff
-is a wrapper program for the GNU text processing system,
-.BR  groff .
-It transparently handles the mechanics of multiple pass
-.B groff
-processing, when applied to suitably marked up
-.B groff
-source files,
-such that tables of contents and body text are formatted separately,
-and are subsequently combined in the correct order, for final publication
-as a single PDF document.
-A further optional
-.Q style\0sheet
-capability is provided;
-this allows for the definition of content which is required to preceed the
-table of contents, in the published document.
-.P
-For each invocation of
-.BR pdfroff ,
-the ultimate
-.B groff
-output stream is post\(hyprocessed by the GhostScript interpreter,
-to produce a finished PDF document.
-.P
-.B pdfroff
-makes no assumptions about, and imposes no restrictions on,
-the use of any
-.B groff
-macro packages which the user may choose to employ,
-in order to achieve a desired document format;
-however, it
-.I does
-include specific built in support for the
-.B pdfmark
-macro package, should the user choose to employ it.
-Specifically, if the
-.I pdfhref
-macro, defined in the
-.B pdfmark.tmac
-package, is used to define public reference marks,
-or dynamic links to such reference marks, then
-.B pdfroff
-will perform as many preformatting
-.B groff
-passes as required, up to a maximum limit of
-.IR four ,
-in order to compile a document reference dictionary,
-to resolve references, and to expand the dynamically defined
-content of links.
-.
-.\" --------------------------------------------------------------------
-.
-.SH USAGE
-.B pdfroff
-usage closely mirrors that of
-.B groff
-itself.
-Indeed,
-with the exception of the
-.BR \-h ,
-.BR \-v ,
-and
-.BI \-T \0dev
-short form options, and
-all long form options,
-which are parsed internally by
-.BR pdfroff ,
-all options and file name arguments specified on the command line are
-passed on to
-.BR groff ,
-to control the formatting of the PDF document.
-Consequently,
-.B pdfroff
-accepts all options and arguments, as specified in
-.BR groff (@MAN1EXT@),
-which may also be considered as the definitive reference for all standard
-.BR pdfroff
-options and argument usage.
-.
-.\" --------------------------------------------------------------------
-.
-.SH OPTIONS
-.B pdfroff
-accepts all of the short form options
-(i.e., those introduced by a single hyphen),
-which are available with
-.B groff
-itself.
-In most cases, these are simply passed transparently to
-.BR groff ;
-the following, however, are handled specially by
-.BR pdfroff .
-.TP
-.B \-h
-Same as
-.BR \-\-help ;
-see below.
-.TP
-.B \-i
-Process standard input, after all other specified input files.
-This is passed transparently to
-.BR groff ,
-but, if grouped with other options, it
-.I must
-be the first in the group.
-Hiding it within a group will
-break standard input processing, in the multiple pass
-.B groff
-processing context of
-.BR pdfroff .
-.TP
-.BI \-T \0dev
-Only
-.BI \-T \0ps
-is supported by
-.BR pdfroff .
-Attempting to specify any other device will cause
-.B pdfroff
-to abort.
-.TP
-.B \-v
-Same as
-.BR \-\-version ;
-see below.
-.P
-See
-.BR groff (@MAN1EXT@)
-for a description of all other short form options,
-which are transparently passed through
-.BR pdfroff
-to
-.BR groff .
-.P
-All long form options
-(i.e., those introduced by a double hyphen)
-are interpreted locally by
-.BR pdfroff ;
-they are
-.B not
-passed on to
-.BR groff ,
-unless otherwise stated below.
-.TP
-.B \-\-help
-Causes
-.B pdfroff
-to display a summary of the its usage syntax, and supported options,
-and then exit.
-.TP
-.B \-\-no\-pdf\-output
-May be used with the
-.BI \-\-reference\-dictionary= name
-option (described below) to eliminate the overhead of PDF formatting,
-when running
-.B pdfroff
-to create a reference dictionary, for use in a different document.
-.TP
-.B \-\-no\-reference\-dictionary
-May be used to eliminate the overhead of creating a reference dictionary,
-when it is known that the target PDF document will contain no public
-references, created by the
-.I pdfhref
-macro.
-.TP
-.B \-\-no\-toc\-relocation
-May be used to eliminate the extra
-.B groff
-processing pass,
-which is required to generate a table of contents,
-and relocate it to the start of the PDF document,
-when processing any document which lacks an automatically
-generated table of contents.
-.TP
-.BI \-\-pdf\-output= name
-Specifies the name to be used for the resultant PDF document;
-if unspecified, the PDF output is written to standard output.
-A future version of
-.B pdfroff
-may use this option,
-to encode the document name in a generated reference dictionary.
-.TP
-.BI \-\-reference\-dictionary= name
-Specifies the name to be used for the generated reference dictionary file;
-if unspecified, the reference dictionary is created in a temporary file,
-which is deleted when
-.B pdfroff
-completes processing of the current document.
-This option
-.I must
-be specified, if it is desired to save the reference dictionary,
-for use in references placed in other PDF documents.
-.TP
-.B \-\-report\-progress
-Causes
-.B pdfroff
-to display an informational message on standard error,
-at the start of each
-.B groff
-processing pass.
-.TP
-.BI \-\-stylesheet= name
-Specifies the name of an
-.IR "input file" ,
-to be used as a style sheet for formatting of content,
-which is to be placed
-.I before
-the table of contents,
-in the formatted PDF document.
-.TP
-.B \-\-version
-Causes
-.B pdfroff
-to display a version identification message.
-The entire command line is then passed transparently to
-.BR groff ,
-in a
-.I one
-pass operation
-.IR only ,
-in order to display the associated
-.B groff
-version information, before exiting.
-.
-.\" --------------------------------------------------------------------
-.
-.SH ENVIRONMENT
-The following environment variables may be set, and exported,
-to modify the behaviour of
-.BR pdfroff .
-.TP
-.B GROFF_TMPDIR
-Identifies the directory in which
-.B pdfroff
-should create temporary files.
-If
-.B GROFF_TMPDIR
-is
-.I not
-specified, then the variables
-.BR TMPDIR ,
-.B TMP
-and
-.B TEMP
-are considered in turn, as possible temporary file repositories.
-If none of these are set, then temporary files will be created
-in the current directory.
-.TP
-.B GROFF_GHOSTSCRIPT_INTERPRETER
-Specifies the program to be invoked, when
-.B pdfroff
-converts
-.B groff
-PostScript output to PDF.
-If
-.B GROFF_GHOSTSCRIPT_INTERPRETER
-is not specified, then
-.B pdfroff
-will search the process
-.BR PATH ,
-looking for a program with any of the well known names
-for the GhostScript interpreter;
-if no GhostScript interpreter can be found,
-.B pdfroff
-will abort.
-.TP
-.B GROFF_AWK_INTERPRETER
-Specifies the program to be invoked, when
-.B pdfroff
-is extracting reference dictionary entries from a
-.B groff
-intermediate message stream.
-If
-.B GROFF_AWK_INTERPRETER
-is not specified, then
-.B pdfroff
-will search the process
-.BR PATH ,
-looking for any of the preferred programs, `gawk', `mawk', `nawk'
-and `awk', in this order;
-if none of these are found,
-.B pdfroff
-will issue a warning message, and continue processing;
-however, in this case, no reference dictionary will be created.
-.TP
-.B OSTYPE
-Typically defined automatically by the operating system,
-.B OSTYPE
-is used on Microsoft Win32/MS\(hyDOS platforms
-.IR only ,
-to infer the default
-.B PATH_SEPARATOR
-character,
-which is used when parsing the process
-.B PATH
-to search for external helper programs.
-.TP
-.B PATH_SEPARATOR
-If set,
-.B PATH_SEPARATOR
-overrides the default separator character,
-(':' on POSIX/UNIX systems,
-inferred from
-.B OSTYPE
-on Microsoft Win32/MS\(hyDOS),
-which is used when parsing the process
-.B PATH
-to search for external helper programs.
-.TP
-.B SHOW_PROGRESS
-If this is set to a non-empty value, then
-.B pdfroff
-will always behave as if the
-.B \-\-report\-progress
-option is specified, on the command line.
-.
-.\" --------------------------------------------------------------------
-.
-.SH FILES
-Input and output files for
-.B pdfroff
-may be named according to any convention of the user's choice.
-Typically, input files may be named according to the choice of the
-principal formatting macro package, e.g.,
-.IB file .ms
-might be an input file for formatting using the
-.B ms
-macros
-.RB ( s.tmac );
-normally, the final output file should be named
-.IB file .pdf\c
-\&.
-.P
-Temporary files, created by
-.BR pdfroff ,
-are placed in the directory specified by environment variables (see
-section
-.BR ENVIRONMENT ),
-and named according to the convention
-.BI pdf $$ .*\c
-\&, where
-.I $$
-is the standard shell variable representing the process ID of the
-.B pdfroff
-process itself, and
-.I *
-represents any of a number of extensions used by
-.B pdfroff
-for temporary and intermediate files.
-.

-.TH PIC2GRAPH @MAN1EXT@ "@MDATE@" "Groff Version @VERSION@"
-.IX pic2graph
-.SH NAME
-pic2graph \- convert a PIC diagram into a cropped image
-.
-.
-.SH SYNOPSIS
-.B pic2graph
-[
-.B \-unsafe
-]
-[
-.BI \-format\  fmt
-]
-[
-.BI \-eqn\  delim
-]
-.
-.
-.SH DESCRIPTION
-Reads a PIC program as input; produces an image file (by default in
-Portable Network Graphics format) suitable for the Web as output.
-Also translates
-.BR @g@eqn (@MAN1EXT@)
-constructs, so it can be used for generating images of mathematical
-formulae.
-.P
-PIC is a rather expressive graphics minilanguage suitable for
-producing box-and-arrow diagrams of the kind frequently used in
-technical papers and textbooks.  The language is sufficiently flexible
-to be quite useful for state charts, Petri-net diagrams, flow charts,
-simple circuit schematics, jumper layouts, and other kinds of
-illustration involving repetitive uses of simple geometric forms and
-splines.  Because PIC descriptions are procedural and object-based,
-they are both compact and easy to modify.
-.P
-The PIC language is fully documented in "\fIMaking Pictures With GNU
-PIC\fP", a document which is part of the
-.BR groff (@MAN1EXT@)
-distribution.
-.P
-Your input PIC code should \fInot\fR be wrapped with the .PS and .PE macros
-that normally guard it within 
-.BR groff (@MAN1EXT@) 
-macros.
-.P
-The output image will be a black-on-white graphic clipped to the
-smallest possible bounding box that contains all the black pixels.
-By specifying command-line options to be passed to 
-.BR convert (1)
-you can give it a border, set the background transparent, set the
-image's pixel density, or perform other useful transformations.
-.P
-This program uses 
-.BR @g@pic (@MAN1EXT@),
-.BR @g@eqn (@MAN1EXT@),
-.BR groff (@MAN1EXT@),
-.BR gs (1),
-and the ImageMagick
-.BR convert (1)
-program.
-These programs must be installed on your system and accessible on your
-$PATH for \fBpic2graph\fR to work.
-.
-.
-.SH OPTIONS
-.TP
-.B \-unsafe
-Run 
-.BR @g@pic (@MAN1EXT@)
-and
-.BR groff (@MAN1EXT@)
-in the `unsafe' mode enabling the PIC macro
-.B sh
-to execute arbitrary commands.  The default is to forbid this.
-.TP
-.BI \-format\  fmt
-Specify an output format; the default is PNG (Portable Network Graphics).
-Any format that
-.BR convert (1)
-can emit is supported.
-.TP
-.BI \-eqn\  delim
-Change the fencepost characters that delimit 
-.BR @g@eqn (@MAN1EXT@)
-directives
-.RB ( $
-and
-.BR $ ,
-by default).  This option requires an argument, but an empty string is
-accepted as a directive to disable
-.BR @g@eqn (@MAN1EXT@)
-processing.
-.PP
-Command-line switches and arguments not listed above are passed to
-.BR convert (1).
-.
-.
-.SH FILES
-.TP \w'\fB@MACRODIR@/eqnrc'u+2n
-.B @MACRODIR@/eqnrc
-The 
-.BR @g@eqn (@MAN1EXT@)
-initialization file.
-.
-.
-.SH ENVIRONMENT
-.TP
-.B GROFF_TMPDIR
-The directory in which temporary files will be created.
-If this is not set
-.B pic2graph
-searches the environment variables
-.BR \%TMPDIR ,
-.BR TMP ,
-and
-.B TEMP
-(in that order).
-Otherwise, temporary files will be created in
-.BR /tmp .

-# pic2graph -- compile PIC image descriptions to bitmap images
-#
-# by Eric S. Raymond <esr@thyrsus.com>, July 2002
-
-# In Unixland, the magic is in knowing what to string together...
-#
-# Take a pic/eqn diagram on stdin, emit cropped bitmap on stdout.
-# The pic markup should *not* be wrapped in .PS/.PE, this script will do that.
-# An -unsafe option on the command line enables gpic/groff "unsafe" mode.
-# A -format FOO option changes the image output format to any format
-# supported by convert(1).  An -eqn option changes the eqn delimiters.
-# All other options are passed to convert(1).  The default format in PNG.
-#
-# Requires the groff suite and the ImageMagick tools.  Both are open source.
-# This code is released to the public domain.
-#
-# Here are the assumptions behind the option processing:
-#
-# 1. Only the -U option of gpic(1) is relevant.  -C doesn't matter because
-#    we're generating our own .PS/.PE, -[ntcz] are irrelevant because we're
-#    generating Postscript.
-#
-# 2. Ditto for groff(1), though it's a longer and more tedious demonstration.
-#
-# 3. Many options of convert(1) are potentially relevant (especially 
-#    -density, -interlace, -transparency, -border, and -comment).
-#
-# Thus, we pass -U to gpic and groff, and everything else to convert(1).
-#
-# We don't have complete option coverage on eqn because this is primarily
-# intended as a pic translator; we can live with eqn defaults.

-@center Version 1.2, November 2002
-
-@display
-Copyright @copyright{} 2000,2001,2002 Free Software Foundation, Inc.
-51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA
-
-Everyone is permitted to copy and distribute verbatim copies
-of this license document, but changing it is not allowed.
-@end display
-
-@enumerate 0
-@item
-PREAMBLE
-
-The purpose of this License is to make a manual, textbook, or other
-functional and useful document @dfn{free} in the sense of freedom: to
-assure everyone the effective freedom to copy and redistribute it,
-with or without modifying it, either commercially or noncommercially.
-Secondarily, this License preserves for the author and publisher a way
-to get credit for their work, while not being considered responsible
-for modifications made by others.
-
-This License is a kind of ``copyleft'', which means that derivative
-works of the document must themselves be free in the same sense.  It
-complements the GNU General Public License, which is a copyleft
-license designed for free software.
-
-We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free
-program should come with manuals providing the same freedoms that the
-software does.  But this License is not limited to software manuals;
-it can be used for any textual work, regardless of subject matter or
-whether it is published as a printed book.  We recommend this License
-principally for works whose purpose is instruction or reference.
-
-@item
-APPLICABILITY AND DEFINITIONS
-
-This License applies to any manual or other work, in any medium, that
-contains a notice placed by the copyright holder saying it can be
-distributed under the terms of this License.  Such a notice grants a
-world-wide, royalty-free license, unlimited in duration, to use that
-work under the conditions stated herein.  The ``Document'', below,
-refers to any such manual or work.  Any member of the public is a
-licensee, and is addressed as ``you''.  You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-
-A ``Modified Version'' of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-
-A ``Secondary Section'' is a named appendix or a front-matter section
-of the Document that deals exclusively with the relationship of the
-publishers or authors of the Document to the Document's overall
-subject (or to related matters) and contains nothing that could fall
-directly within that overall subject.  (Thus, if the Document is in
-part a textbook of mathematics, a Secondary Section may not explain
-any mathematics.)  The relationship could be a matter of historical
-connection with the subject or with related matters, or of legal,
-commercial, philosophical, ethical or political position regarding
-them.
-
-The ``Invariant Sections'' are certain Secondary Sections whose titles
-are designated, as being those of Invariant Sections, in the notice
-that says that the Document is released under this License.  If a
-section does not fit the above definition of Secondary then it is not
-allowed to be designated as Invariant.  The Document may contain zero
-Invariant Sections.  If the Document does not identify any Invariant
-Sections then there are none.
-
-The ``Cover Texts'' are certain short passages of text that are listed,
-as Front-Cover Texts or Back-Cover Texts, in the notice that says that
-the Document is released under this License.  A Front-Cover Text may
-be at most 5 words, and a Back-Cover Text may be at most 25 words.
-
-A ``Transparent'' copy of the Document means a machine-readable copy,
-represented in a format whose specification is available to the
-general public, that is suitable for revising the document
-straightforwardly with generic text editors or (for images composed of
-pixels) generic paint programs or (for drawings) some widely available
-drawing editor, and that is suitable for input to text formatters or
-for automatic translation to a variety of formats suitable for input
-to text formatters.  A copy made in an otherwise Transparent file
-format whose markup, or absence of markup, has been arranged to thwart
-or discourage subsequent modification by readers is not Transparent.
-An image format is not Transparent if used for any substantial amount
-of text.  A copy that is not ``Transparent'' is called ``Opaque''.
-
-Examples of suitable formats for Transparent copies include plain
-@sc{ascii} without markup, Texinfo input format, La@TeX{} input
-format, @acronym{SGML} or @acronym{XML} using a publicly available
-@acronym{DTD}, and standard-conforming simple @acronym{HTML},
-PostScript or @acronym{PDF} designed for human modification.  Examples
-of transparent image formats include @acronym{PNG}, @acronym{XCF} and
-@acronym{JPG}.  Opaque formats include proprietary formats that can be
-read and edited only by proprietary word processors, @acronym{SGML} or
-@acronym{XML} for which the @acronym{DTD} and/or processing tools are
-not generally available, and the machine-generated @acronym{HTML},
-PostScript or @acronym{PDF} produced by some word processors for
-output purposes only.
-
-The ``Title Page'' means, for a printed book, the title page itself,
-plus such following pages as are needed to hold, legibly, the material
-this License requires to appear in the title page.  For works in
-formats which do not have any title page as such, ``Title Page'' means
-the text near the most prominent appearance of the work's title,
-preceding the beginning of the body of the text.
-
-A section ``Entitled XYZ'' means a named subunit of the Document whose
-title either is precisely XYZ or contains XYZ in parentheses following
-text that translates XYZ in another language.  (Here XYZ stands for a
-specific section name mentioned below, such as ``Acknowledgements'',
-``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
-of such a section when you modify the Document means that it remains a
-section ``Entitled XYZ'' according to this definition.
-
-The Document may include Warranty Disclaimers next to the notice which
-states that this License applies to the Document.  These Warranty
-Disclaimers are considered to be included by reference in this
-License, but only as regards disclaiming warranties: any other
-implication that these Warranty Disclaimers may have is void and has
-no effect on the meaning of this License.
-
-@item
-VERBATIM COPYING
-
-You may copy and distribute the Document in any medium, either
-commercially or noncommercially, provided that this License, the
-copyright notices, and the license notice saying this License applies
-to the Document are reproduced in all copies, and that you add no other
-conditions whatsoever to those of this License.  You may not use
-technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute.  However, you may accept
-compensation in exchange for copies.  If you distribute a large enough
-number of copies you must also follow the conditions in section 3.
-
-You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-
-@item
-COPYING IN QUANTITY
-
-If you publish printed copies (or copies in media that commonly have
-printed covers) of the Document, numbering more than 100, and the
-Document's license notice requires Cover Texts, you must enclose the
-copies in covers that carry, clearly and legibly, all these Cover
-Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
-the back cover.  Both covers must also clearly and legibly identify
-you as the publisher of these copies.  The front cover must present
-the full title with all words of the title equally prominent and
-visible.  You may add other material on the covers in addition.
-Copying with changes limited to the covers, as long as they preserve
-the title of the Document and satisfy these conditions, can be treated
-as verbatim copying in other respects.
-
-If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-
-If you publish or distribute Opaque copies of the Document numbering
-more than 100, you must either include a machine-readable Transparent
-copy along with each Opaque copy, or state in or with each Opaque copy
-a computer-network location from which the general network-using
-public has access to download using public-standard network protocols
-a complete Transparent copy of the Document, free of added material.
-If you use the latter option, you must take reasonably prudent steps,
-when you begin distribution of Opaque copies in quantity, to ensure
-that this Transparent copy will remain thus accessible at the stated
-location until at least one year after the last time you distribute an
-Opaque copy (directly or through your agents or retailers) of that
-edition to the public.
-
-It is requested, but not required, that you contact the authors of the
-Document well before redistributing any large number of copies, to give
-them a chance to provide you with an updated version of the Document.
-
-@item
-MODIFICATIONS
-
-You may copy and distribute a Modified Version of the Document under
-the conditions of sections 2 and 3 above, provided that you release
-the Modified Version under precisely this License, with the Modified
-Version filling the role of the Document, thus licensing distribution
-and modification of the Modified Version to whoever possesses a copy
-of it.  In addition, you must do these things in the Modified Version:
-
-@enumerate A
-@item
-Use in the Title Page (and on the covers, if any) a title distinct
-from that of the Document, and from those of previous versions
-(which should, if there were any, be listed in the History section
-of the Document).  You may use the same title as a previous version
-if the original publisher of that version gives permission.
-
-@item
-List on the Title Page, as authors, one or more persons or entities
-responsible for authorship of the modifications in the Modified
-Version, together with at least five of the principal authors of the
-Document (all of its principal authors, if it has fewer than five),
-unless they release you from this requirement.
-
-@item
-State on the Title page the name of the publisher of the
-Modified Version, as the publisher.
-
-@item
-Preserve all the copyright notices of the Document.
-
-@item
-Add an appropriate copyright notice for your modifications
-adjacent to the other copyright notices.
-
-@item
-Include, immediately after the copyright notices, a license notice
-giving the public permission to use the Modified Version under the
-terms of this License, in the form shown in the Addendum below.
-
-@item
-Preserve in that license notice the full lists of Invariant Sections
-and required Cover Texts given in the Document's license notice.
-
-@item
-Include an unaltered copy of this License.
-
-@item
-Preserve the section Entitled ``History'', Preserve its Title, and add
-to it an item stating at least the title, year, new authors, and
-publisher of the Modified Version as given on the Title Page.  If
-there is no section Entitled ``History'' in the Document, create one
-stating the title, year, authors, and publisher of the Document as
-given on its Title Page, then add an item describing the Modified
-Version as stated in the previous sentence.
-
-@item
-Preserve the network location, if any, given in the Document for
-public access to a Transparent copy of the Document, and likewise
-the network locations given in the Document for previous versions
-it was based on.  These may be placed in the ``History'' section.
-You may omit a network location for a work that was published at
-least four years before the Document itself, or if the original
-publisher of the version it refers to gives permission.
-
-@item
-For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
-the Title of the section, and preserve in the section all the
-substance and tone of each of the contributor acknowledgements and/or
-dedications given therein.
-
-@item
-Preserve all the Invariant Sections of the Document,
-unaltered in their text and in their titles.  Section numbers
-or the equivalent are not considered part of the section titles.
-
-@item
-Delete any section Entitled ``Endorsements''.  Such a section
-may not be included in the Modified Version.
-
-@item
-Do not retitle any existing section to be Entitled ``Endorsements'' or
-to conflict in title with any Invariant Section.
-
-@item
-Preserve any Warranty Disclaimers.
-@end enumerate
-
-If the Modified Version includes new front-matter sections or
-appendices that qualify as Secondary Sections and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant.  To do this, add their titles to the
-list of Invariant Sections in the Modified Version's license notice.
-These titles must be distinct from any other section titles.
-
-You may add a section Entitled ``Endorsements'', provided it contains
-nothing but endorsements of your Modified Version by various
-parties---for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-
-You may add a passage of up to five words as a Front-Cover Text, and a
-passage of up to 25 words as a Back-Cover Text, to the end of the list
-of Cover Texts in the Modified Version.  Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or
-through arrangements made by) any one entity.  If the Document already
-includes a cover text for the same cover, previously added by you or
-by arrangement made by the same entity you are acting on behalf of,
-you may not add another; but you may replace the old one, on explicit
-permission from the previous publisher that added the old one.
-
-The author(s) and publisher(s) of the Document do not by this License
-give permission to use their names for publicity for or to assert or
-imply endorsement of any Modified Version.
-
-@item
-COMBINING DOCUMENTS
-
-You may combine the Document with other documents released under this
-License, under the terms defined in section 4 above for modified
-versions, provided that you include in the combination all of the
-Invariant Sections of all of the original documents, unmodified, and
-list them all as Invariant Sections of your combined work in its
-license notice, and that you preserve all their Warranty Disclaimers.
-
-The combined work need only contain one copy of this License, and
-multiple identical Invariant Sections may be replaced with a single
-copy.  If there are multiple Invariant Sections with the same name but
-different contents, make the title of each such section unique by
-adding at the end of it, in parentheses, the name of the original
-author or publisher of that section if known, or else a unique number.
-Make the same adjustment to the section titles in the list of
-Invariant Sections in the license notice of the combined work.
-
-In the combination, you must combine any sections Entitled ``History''
-in the various original documents, forming one section Entitled
-``History''; likewise combine any sections Entitled ``Acknowledgements'',
-and any sections Entitled ``Dedications''.  You must delete all
-sections Entitled ``Endorsements.''
-
-@item
-COLLECTIONS OF DOCUMENTS
-
-You may make a collection consisting of the Document and other documents
-released under this License, and replace the individual copies of this
-License in the various documents with a single copy that is included in
-the collection, provided that you follow the rules of this License for
-verbatim copying of each of the documents in all other respects.
-
-You may extract a single document from such a collection, and distribute
-it individually under this License, provided you insert a copy of this
-License into the extracted document, and follow this License in all
-other respects regarding verbatim copying of that document.
-
-@item
-AGGREGATION WITH INDEPENDENT WORKS
-
-A compilation of the Document or its derivatives with other separate
-and independent documents or works, in or on a volume of a storage or
-distribution medium, is called an ``aggregate'' if the copyright
-resulting from the compilation is not used to limit the legal rights
-of the compilation's users beyond what the individual works permit.
-When the Document is included in an aggregate, this License does not
-apply to the other works in the aggregate which are not themselves
-derivative works of the Document.
-
-If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one half of
-the entire aggregate, the Document's Cover Texts may be placed on
-covers that bracket the Document within the aggregate, or the
-electronic equivalent of covers if the Document is in electronic form.
-Otherwise they must appear on printed covers that bracket the whole
-aggregate.
-
-@item
-TRANSLATION
-
-Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections.  You may include a
-translation of this License, and all the license notices in the
-Document, and any Warranty Disclaimers, provided that you also include
-the original English version of this License and the original versions
-of those notices and disclaimers.  In case of a disagreement between
-the translation and the original version of this License or a notice
-or disclaimer, the original version will prevail.
-
-If a section in the Document is Entitled ``Acknowledgements'',
-``Dedications'', or ``History'', the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-
-@item
-TERMINATION
-
-You may not copy, modify, sublicense, or distribute the Document except
-as expressly provided for under this License.  Any other attempt to
-copy, modify, sublicense or distribute the Document is void, and will
-automatically terminate your rights under this License.  However,
-parties who have received copies, or rights, from you under this
-License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-@item
-FUTURE REVISIONS OF THIS LICENSE
-
-The Free Software Foundation may publish new, revised versions
-of the GNU Free Documentation License from time to time.  Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.  See
-@uref{http://www.gnu.org/copyleft/}.
-
-Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License ``or any later version'' applies to it, you have the option of
-following the terms and conditions either of that specified version or
-of any later version that has been published (not as a draft) by the
-Free Software Foundation.  If the Document does not specify a version
-number of this License, you may choose any version ever published (not
-as a draft) by the Free Software Foundation.
-@end enumerate
-
-@page
-@appendixsubsec ADDENDUM: How to use this License for your documents
-
-To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and
-license notices just after the title page:
-
-@smallexample
-@group
-  Copyright (C)  @var{year}  @var{your name}.
-  Permission is granted to copy, distribute and/or modify this document
-  under the terms of the GNU Free Documentation License, Version 1.2
-  or any later version published by the Free Software Foundation;
-  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
-  Texts.  A copy of the license is included in the section entitled ``GNU
-  Free Documentation License''.
-@end group
-@end smallexample
-
-If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
-replace the ``with...Texts.'' line with this:
-
-@smallexample
-@group
-    with the Invariant Sections being @var{list their titles}, with
-    the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
-    being @var{list}.
-@end group
-@end smallexample
-
-If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-
-If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License,
-to permit their use in free software.

-#   @deffn ...
-#   @XXindex ...
-#   @deffnx ...
-#
-# which has worked with earlier versions (using an undocumented feature
-# of the implementation of @deffn and @deffnx).  Version 4.8 has new
-# code for generating HTML, and the above construction produces wrong
-# HTML output: It starts a new <blockquote> without closing it properly.
-# The very problem is that, according to the documentation, the @deffnx
-# must immediately follow the @deffn line, making it impossible to add
-# entries into user-defined indices if supplied with macro wrappers around
-# @deffn and @deffnx.
-#
-# Note that this script is a quick hack and tightly bound to the current
-# groff.texinfo macro code.  Hopefully, a new texinfo version makes it
-# unnecessary.

-The following slide shows the complete schematics of the
-fully-differential RIC. The operation includes a
-correlated-double-sampling phase that occurs once every 256
-clock periods, also called the
-.i "spreading ratio" .
-This reset phase is controlled by clocks $ DP sub 1 $ and $ DP
-sub 2 $ in which the integrator is initialized by totally
-removing the charge from $ cc F $ and storing the low-frequency
-noise of the op amp in $ cc C $. At the same time the comparison
-thresholds are set.

-The faster clocks are $ PN $, $ ITS $ and $ SP $. The sampling
-capacitor $ cc S $ performs the delayed subtraction of a sample
-of the input signal $ +- ^ vv SIG $ and a choice of $ - ^ vv REF
-$, $ AGND $ or $ + ^ vv REF $ according to the operations
-performed by the logic partially depicted operating on past
-results of the comparisons. The synchronous comparators are
-reset at this fast rates, thus performing one comparison for
-every fast clock cycle. The dynamic common-mode feedback
-arrangement operates synchronously with the reset time slot and
-its configuration is equivalent to that in the differential
-feedback path.

-1 Introduction
-**************
-
-GNU `troff' (or `groff') is a system for typesetting documents.
-`troff' is very flexible and has been in existence (and use) for about
-3 decades.  It is quite widespread and firmly entrenched in the UNIX
-community.

-1.1 What Is `groff'?
-====================
-
-`groff' belongs to an older generation of document preparation systems,
-which operate more like compilers than the more recent interactive
-WYSIWYG(1) (*note What Is groff?-Footnote-1::) systems.  `groff' and
-its contemporary counterpart, TeX, both work using a "batch" paradigm:
-The input (or "source") files are normal text files with embedded
-formatting commands.  These files can then be processed by `groff' to
-produce a typeset document on a variety of devices.
-
-   Likewise, `groff' should not be confused with a "word processor",
-since that term connotes an integrated system that includes an editor
-and a text formatter.  Also, many word processors follow the WYSIWYG
-paradigm discussed earlier.
-
-   Although WYSIWYG systems may be easier to use, they have a number of
-disadvantages compared to `troff':
-
-   * They must be used on a graphics display to work on a document.
-
-   * Most of the WYSIWYG systems are either non-free or are not very
-     portable.
-
-   * `troff' is firmly entrenched in all UNIX systems.
-
-   * It is difficult to have a wide range of capabilities available
-     within the confines of a GUI/window system.
-
-   * It is more difficult to make global changes to a document.
-
-     "GUIs normally make it simple to accomplish simple actions and
-     impossible to accomplish complex actions."  -Doug Gwyn (22/Jun/91
-     in `comp.unix.wizards')

-
-1.2 History
-===========
-
-`troff' can trace its origins back to a formatting program called
-`runoff', written by J. E. Saltzer, which ran on MIT's CTSS operating
-system in the mid-sixties.  This name came from the common phrase of
-the time "I'll run off a document."  Bob Morris ported it to the 635
-architecture and called the program `roff' (an abbreviation of
-`runoff').  It was rewritten as `rf' for the PDP-7 (before having
-UNIX), and at the same time (1969), Doug McIllroy rewrote an extended
-and simplified version of `roff' in the BCPL programming language.
-
-   The first version of UNIX was developed on a PDP-7 which was sitting
-around Bell Labs.  In 1971 the developers wanted to get a PDP-11 for
-further work on the operating system.  In order to justify the cost for
-this system, they proposed that they would implement a document
-formatting system for the AT&T patents division.  This first formatting
-program was a reimplementation of McIllroy's `roff', written by
-J. F. Ossanna.
-
-   When they needed a more flexible language, a new version of `roff'
-called `nroff' ("Newer `roff'") was written.  It had a much more
-complicated syntax, but provided the basis for all future versions.
-When they got a Graphic Systems CAT Phototypesetter, Ossanna wrote a
-version of `nroff' that would drive it.  It was dubbed `troff', for
-"typesetter `roff'", although many people have speculated that it
-actually means "Times `roff'" because of the use of the Times font
-family in `troff' by default.  As such, the name `troff' is pronounced
-`t-roff' rather than `trough'.
-
-   With `troff' came `nroff' (they were actually the same program
-except for some `#ifdef's), which was for producing output for line
-printers and character terminals.  It understood everything `troff'
-did, and ignored the commands which were not applicable (e.g. font
-changes).
-
-   Since there are several things which cannot be done easily in
-`troff', work on several preprocessors began.  These programs would
-transform certain parts of a document into `troff', which made a very
-natural use of pipes in UNIX.
-
-   The `eqn' preprocessor allowed mathematical formulæ to be specified
-in a much simpler and more intuitive manner.  `tbl' is a preprocessor
-for formatting tables.  The `refer' preprocessor (and the similar
-program, `bib') processes citations in a document according to a
-bibliographic database.
-
-   Unfortunately, Ossanna's `troff' was written in PDP-11 assembly
-language and produced output specifically for the CAT phototypesetter.
-He rewrote it in C, although it was now 7000 lines of uncommented code
-and still dependent on the CAT.  As the CAT became less common, and was
-no longer supported by the manufacturer, the need to make it support
-other devices became a priority.  However, before this could be done,
-Ossanna was killed in a car accident.
-
-   So, Brian Kernighan took on the task of rewriting `troff'.  The
-newly rewritten version produced device independent code which was very
-easy for postprocessors to read and translate to the appropriate
-printer codes.  Also, this new version of `troff' (called `ditroff' for
-"device independent `troff'") had several extensions, which included
-drawing functions.
-
-   Due to the additional abilities of the new version of `troff',
-several new preprocessors appeared.  The `pic' preprocessor provides a
-wide range of drawing functions.  Likewise the `ideal' preprocessor did
-the same, although via a much different paradigm.  The `grap'
-preprocessor took specifications for graphs, but, unlike other
-preprocessors, produced `pic' code.
-
-   James Clark began work on a GNU implementation of `ditroff' in
-early 1989.  The first version, `groff' 0.3.1, was released June 1990.
-`groff' included:
-
-   * A replacement for `ditroff' with many extensions.
-
-   * The `soelim', `pic', `tbl', and `eqn' preprocessors.
-
-   * Postprocessors for character devices, POSTSCRIPT, TeX DVI, and
-     X Windows.  GNU `troff' also eliminated the need for a separate
-     `nroff' program with a postprocessor which would produce ASCII
-     output.
-
-   * A version of the `me' macros and an implementation of the `man'
-     macros.
-
-   Also, a front-end was included which could construct the, sometimes
-painfully long, pipelines required for all the post- and preprocessors.
-
-   Development of GNU `troff' progressed rapidly, and saw the additions
-of a replacement for `refer', an implementation of the `ms' and `mm'
-macros, and a program to deduce how to format a document (`grog').
-
-   It was declared a stable (i.e. non-beta) package with the release of
-version 1.04 around November 1991.
-
-   Beginning in 1999, `groff' has new maintainers (the package was an
-orphan for a few years).  As a result, new features and programs like
-`grn', a preprocessor for gremlin images, and an output device to
-produce HTML output have been added.

-1.3 `groff' Capabilities
-========================
-
-So what exactly is `groff' capable of doing?  `groff' provides a wide
-range of low-level text formatting operations.  Using these, it is
-possible to perform a wide range of formatting tasks, such as
-footnotes, table of contents, multiple columns, etc.  Here's a list of
-the most important operations supported by `groff':
-
-   * text filling, adjusting, and centering
-
-   * hyphenation
-
-   * page control
-
-   * font and glyph size control
-
-   * vertical spacing (e.g. double-spacing)
-
-   * line length and indenting
-
-   * macros, strings, diversions, and traps
-
-   * number registers
-
-   * tabs, leaders, and fields
-
-   * input and output conventions and character translation
-
-   * overstrike, bracket, line drawing, and zero-width functions
-
-   * local horizontal and vertical motions and the width function
-
-   * three-part titles
-
-   * output line numbering
-
-   * conditional acceptance of input
-
-   * environment switching
-
-   * insertions from the standard input
-
-   * input/output file switching
-
-   * output and error messages
-
-
-File: groff,  Node: Macro Package Intro,  Next: Preprocessor Intro,  Prev: groff Capabilities,  Up: Introduction
-
-1.4 Macro Packages
-==================
-
-Since `groff' provides such low-level facilities, it can be quite
-difficult to use by itself.  However, `groff' provides a "macro"
-facility to specify how certain routine operations (e.g. starting
-paragraphs, printing headers and footers, etc.)  should be done.  These
-macros can be collected together into a "macro package".  There are a
-number of macro packages available; the most common (and the ones
-described in this manual) are `man', `mdoc', `me', `ms', and `mm'.
-
-
-File: groff,  Node: Preprocessor Intro,  Next: Output device intro,  Prev: Macro Package Intro,  Up: Introduction
-
-1.5 Preprocessors
-=================
-
-Although `groff' provides most functions needed to format a document,
-some operations would be unwieldy (e.g. to draw pictures).  Therefore,
-programs called "preprocessors" were written which understand their own
-language and produce the necessary `groff' operations.  These
-preprocessors are able to differentiate their own input from the rest
-of the document via markers.
-
-   To use a preprocessor, UNIX pipes are used to feed the output from
-the preprocessor into `groff'.  Any number of preprocessors may be used
-on a given document; in this case, the preprocessors are linked
-together into one pipeline.  However, with `groff', the user does not
-need to construct the pipe, but only tell `groff' what preprocessors to
-use.
-
-   `groff' currently has preprocessors for producing tables (`tbl'),
-typesetting equations (`eqn'), drawing pictures (`pic' and `grn'), and
-for processing bibliographies (`refer').  An associated program which
-is useful when dealing with preprocessors is `soelim'.
-
-   A free implementation of `grap', a preprocessor for drawing graphs,
-can be obtained as an extra package; `groff' can use `grap' also.
-
-   There are other preprocessors in existence, but, unfortunately, no
-free implementations are available.  Among them are preprocessors for
-drawing mathematical pictures (`ideal') and chemical structures
-(`chem').

-
-1.6 Output Devices
-==================
-
-`groff' actually produces device independent code which may be fed into
-a postprocessor to produce output for a particular device.  Currently,
-`groff' has postprocessors for POSTSCRIPT devices, character terminals,
-X Windows (for previewing), TeX DVI format, HP LaserJet 4 and Canon LBP
-printers (which use CAPSL), and HTML.

-
-Large portions of this manual were taken from existing documents, most
-notably, the manual pages for the `groff' package by James Clark, and
-Eric Allman's papers on the `me' macro package.
-
-   The section on the `man' macro package is partly based on Susan G.
-Kleinmann's `groff_man' manual page written for the Debian GNU/Linux
-system.
-
-   Larry Kollar contributed the section in the `ms' macro package.

-2 Invoking `groff'
-******************
-
-This section focuses on how to invoke the `groff' front end.  This
-front end takes care of the details of constructing the pipeline among
-the preprocessors, `gtroff' and the postprocessor.
-
-   It has become a tradition that GNU programs get the prefix `g' to
-distinguish it from its original counterparts provided by the host (see
-*Note Environment::, for more details).  Thus, for example, `geqn' is
-GNU `eqn'.  On operating systems like GNU/Linux or the Hurd, which
-don't contain proprietary versions of `troff', and on
-MS-DOS/MS-Windows, where `troff' and associated programs are not
-available at all, this prefix is omitted since GNU `troff' is the only
-used incarnation of `troff'.  Exception: `groff' is never replaced by
-`roff'.
-
-   In this document, we consequently say `gtroff' when talking about
-the GNU `troff' program.  All other implementations of `troff' are
-called AT&T `troff' which is the common origin of all `troff' derivates
-(with more or less compatible changes).  Similarly, we say `gpic',
-`geqn', etc.

-
-2.1 Options
-===========
-
-`groff' normally runs the `gtroff' program and a postprocessor
-appropriate for the selected device.  The default device is `ps' (but
-it can be changed when `groff' is configured and built).  It can
-optionally preprocess with any of `gpic', `geqn', `gtbl', `ggrn',
-`grap', `grefer', or `gsoelim'.
-
-   This section only documents options to the `groff' front end.  Many
-of the arguments to `groff' are passed on to `gtroff', therefore those
-are also included.  Arguments to pre- or postprocessors can be found in
-*Note Invoking gpic::, *Note Invoking geqn::, *Note Invoking gtbl::,
-*Note Invoking ggrn::, *Note Invoking grefer::, *Note Invoking
-gsoelim::, *Note Invoking grotty::, *Note Invoking grops::, *Note
-Invoking grohtml::, *Note Invoking grodvi::, *Note Invoking grolj4::,
-*Note Invoking grolbp::, and *Note Invoking gxditview::.
-
-   The command line format for `groff' is:
-
-
-     groff [ -abceghilpstvzCEGNRSUVXZ ] [ -FDIR ] [ -mNAME ]
-           [ -TDEF ] [ -fFAM ] [ -wNAME ] [ -WNAME ]
-           [ -MDIR ] [ -dCS ] [ -rCN ] [ -nNUM ]
-           [ -oLIST ] [ -PARG ] [ -LARG ] [ -IDIR ]
-           [ FILES... ]
-
-   The command line format for `gtroff' is as follows.
-
-
-     gtroff [ -abcivzCERU ] [ -wNAME ] [ -WNAME ] [ -dCS ]
-            [ -fFAM ] [ -mNAME ] [ -nNUM ]
-            [ -oLIST ] [ -rCN ] [ -TNAME ]
-            [ -FDIR ] [ -MDIR ] [ FILES... ]
-
-Obviously, many of the options to `groff' are actually passed on to
-`gtroff'.
-
-   Options without an argument can be grouped behind a single `-'.  A
-filename of `-' denotes the standard input.  It is possible to have
-whitespace between an option and its parameter.
-
-   The `grog' command can be used to guess the correct `groff' command
-to format a file.
-
-   Here's the description of the command-line options:
-
-`-h'
-     Print a help message.
-
-`-e'
-     Preprocess with `geqn'.
-
-`-t'
-     Preprocess with `gtbl'.
-
-`-g'
-     Preprocess with `ggrn'.
-
-`-G'
-     Preprocess with `grap'.
-
-`-p'
-     Preprocess with `gpic'.
-
-`-s'
-     Preprocess with `gsoelim'.
-
-`-c'
-     Suppress color output.
-
-`-R'
-     Preprocess with `grefer'.  No mechanism is provided for passing
-     arguments to `grefer' because most `grefer' options have
-     equivalent commands which can be included in the file.  *Note
-     grefer::, for more details.
-
-     Note that `gtroff' also accepts a `-R' option, which is not
-     accessible via `groff'.  This option prevents the loading of the
-     `troffrc' and `troffrc-end' files.
-
-`-v'
-     Make programs run by `groff' print out their version number.
-
-`-V'
-     Print the pipeline on `stdout' instead of executing it.  If
-     specified more than once, print the pipeline on `stderr' and
-     execute it.
-
-`-z'
-     Suppress output from `gtroff'.  Only error messages are printed.
-
-`-Z'
-     Do not postprocess the output of `gtroff'.  Normally `groff'
-     automatically runs the appropriate postprocessor.
-
-`-PARG'
-     Pass ARG to the postprocessor.  Each argument should be passed
-     with a separate `-P' option.  Note that `groff' does not prepend
-     `-' to ARG before passing it to the postprocessor.
-
-`-l'
-     Send the output to a spooler for printing.  The command used for
-     this is specified by the `print' command in the device description
-     file (see *Note Font Files::, for more info).  If not present,
-     `-l' is ignored.
-
-`-LARG'
-     Pass ARG to the spooler.  Each argument should be passed with a
-     separate `-L' option.  Note that `groff' does not prepend a `-' to
-     ARG before passing it to the postprocessor.  If the `print'
-     keyword in the device description file is missing, `-L' is ignored.
-
-`-TDEV'
-     Prepare output for device DEV.  The default device is `ps', unless
-     changed when `groff' was configured and built.  The following are
-     the output devices currently available:
-
-    `ps'
-          For POSTSCRIPT printers and previewers.
-
-    `dvi'
-          For TeX DVI format.
-
-    `X75'
-          For a 75dpi X11 previewer.
-
-    `X75-12'
-          For a 75dpi X11 previewer with a 12pt base font in the
-          document.
-
-    `X100'
-          For a 100dpi X11 previewer.
-
-    `X100-12'
-          For a 100dpi X11 previewer with a 12pt base font in the
-          document.
-
-    `ascii'
-          For typewriter-like devices using the (7-bit) ASCII character
-          set.
-
-    `latin1'
-          For typewriter-like devices that support the Latin-1
-          (ISO 8859-1) character set.
-
-    `utf8'
-          For typewriter-like devices which use the Unicode (ISO 10646)
-          character set with UTF-8 encoding.
-
-    `cp1047'
-          For typewriter-like devices which use the EBCDIC encoding IBM
-          cp1047.
-
-    `lj4'
-          For HP LaserJet4-compatible (or other PCL5-compatible)
-          printers.
-
-    `lbp'
-          For Canon CAPSL printers (LBP-4 and LBP-8 series laser
-          printers).
-
-    `html'
-          To produce HTML output.  Note that the HTML driver consists
-          of two parts, a preprocessor (`pre-grohtml') and a
-          postprocessor (`post-grohtml').
-
-     The predefined `gtroff' string register `.T' contains the current
-     output device; the read-only number register `.T' is set to 1 if
-     this option is used (which is always true if `groff' is used to
-     call `gtroff').  *Note Built-in Registers::.
-
-     The postprocessor to be used for a device is specified by the
-     `postpro' command in the device description file.  (*Note Font
-     Files::, for more info.)  This can be overridden with the `-X'
-     option.
-
-`-X'
-     Preview with `gxditview' instead of using the usual postprocessor.
-     This is unlikely to produce good results except with `-Tps'.
-
-     Note that this is not the same as using `-TX75' or `-TX100' to
-     view a document with `gxditview': The former uses the metrics of
-     the specified device, whereas the latter uses X-specific fonts and
-     metrics.
-
-`-N'
-     Don't allow newlines with `eqn' delimiters.  This is the same as
-     the `-N' option in `geqn'.
-
-`-S'
-     Safer mode.  Pass the `-S' option to `gpic' and disable the
-     `open', `opena', `pso', `sy', and `pi' requests.  For security
-     reasons, this is enabled by default.
-
-`-U'
-     Unsafe mode.  This enables the `open', `opena', `pso', `sy', and
-     `pi' requests.
-
-`-a'
-     Generate an ASCII approximation of the typeset output.  The
-     read-only register `.A' is then set to 1.  *Note Built-in
-     Registers::.  A typical example is
-
-
-          groff -a -man -Tdvi troff.man | less
-
-     which shows how lines are broken for the DVI device.  Note that
-     this option is rather useless today since graphic output devices
-     are available virtually everywhere.
-
-`-b'
-     Print a backtrace with each warning or error message.  This
-     backtrace should help track down the cause of the error.  The line
-     numbers given in the backtrace may not always be correct: `gtroff'
-     can get confused by `as' or `am' requests while counting line
-     numbers.
-
-`-i'
-     Read the standard input after all the named input files have been
-     processed.
-
-`-wNAME'
-     Enable warning NAME.  Available warnings are described in *Note
-     Debugging::.  Multiple `-w' options are allowed.
-
-`-WNAME'
-     Inhibit warning NAME.  Multiple `-W' options are allowed.
-
-`-E'
-     Inhibit all error messages.
-
-`-C'
-     Enable compatibility mode.  *Note Implementation Differences::,
-     for the list of incompatibilities between `groff' and AT&T `troff'.
-
-`-dCS'
-`-dNAME=S'
-     Define C or NAME to be a string S.  C must be a one-letter name;
-     NAME can be of arbitrary length.  All string assignments happen
-     before loading any macro file (including the start-up file).
-
-`-fFAM'
-     Use FAM as the default font family.  *Note Font Families::.
-
-`-mNAME'
-     Read in the file `NAME.tmac'.  Normally `groff' searches for this
-     in its macro directories.  If it isn't found, it tries `tmac.NAME'
-     (searching in the same directories).
-
-`-nNUM'
-     Number the first page NUM.
-
-`-oLIST'
-     Output only pages in LIST, which is a comma-separated list of page
-     ranges; `N' means print page N, `M-N' means print every page
-     between M and N, `-N' means print every page up to N, `N-' means
-     print every page beginning with N.  `gtroff' exits after printing
-     the last page in the list.  All the ranges are inclusive on both
-     ends.
-
-     Within `gtroff', this information can be extracted with the `.P'
-     register.  *Note Built-in Registers::.
-
-     If your document restarts page numbering at the beginning of each
-     chapter, then `gtroff' prints the specified page range for each
-     chapter.
-
-`-rCN'
-`-rNAME=N'
-     Set number register C or NAME to the value N.  C must be a
-     one-letter name; NAME can be of arbitrary length.  N can be any
-     `gtroff' numeric expression.  All register assignments happen
-     before loading any macro file (including the start-up file).
-
-`-FDIR'
-     Search `DIR' for subdirectories `devNAME' (NAME is the name of the
-     device), for the `DESC' file, and for font files before looking in
-     the standard directories (*note Font Directories::).  This option
-     is passed to all pre- and postprocessors using the
-     `GROFF_FONT_PATH' environment variable.
-
-`-MDIR'
-     Search directory `DIR' for macro files before the standard
-     directories (*note Macro Directories::).
-
-`-IDIR'
-     This option may be used to specify a directory to search for files.
-     It is passed to the following programs:
-
-        * `gsoelim' (see *Note gsoelim:: for more details); it also
-          implies `groff''s `-s' option.
-
-        * `gtroff'; it is used to search files named in the `psbb' and
-          `so' requests.
-
-        * `grops'; it is used to search files named in the
-          `\X'ps: import' and `\X'ps: file' escapes.
-
-     The current directory is always searched first. This option may be
-     specified more than once; the directories will be searched in the
-     order specified. No directory search is performed for files
-     specified using an absolute path.

-
-2.2 Environment
-===============
-
-There are also several environment variables (of the operating system,
-not within `gtroff') which can modify the behavior of `groff'.
-
-`GROFF_COMMAND_PREFIX'
-     If this is set to X, then `groff' runs `Xtroff' instead of
-     `gtroff'.  This also applies to `tbl', `pic', `eqn', `grn',
-     `refer', and `soelim'.  It does not apply to `grops', `grodvi',
-     `grotty', `pre-grohtml', `post-grohtml', `grolj4', and `gxditview'.
-
-     The default command prefix is determined during the installation
-     process.  If a non-GNU troff system is found, prefix `g' is used,
-     none otherwise.
-
-`GROFF_TMAC_PATH'
-     A colon-separated list of directories in which to search for macro
-     files (before the default directories are tried).  *Note Macro
-     Directories::.
-
-`GROFF_TYPESETTER'
-     The default output device.
-
-`GROFF_FONT_PATH'
-     A colon-separated list of directories in which to search for the
-     `dev'NAME directory (before the default directories are tried).
-     *Note Font Directories::.
-
-`GROFF_BIN_PATH'
-     This search path, followed by `PATH', is used for commands executed
-     by `groff'.
-
-`GROFF_TMPDIR'
-     The directory in which `groff' creates temporary files.  If this is
-     not set and `TMPDIR' is set, temporary files are created in that
-     directory.  Otherwise temporary files are created in a
-     system-dependent default directory (on Unix and GNU/Linux systems,
-     this is usually `/tmp').  `grops', `grefer', `pre-grohtml', and
-     `post-grohtml' can create temporary files in this directory.
-
-   Note that MS-DOS and MS-Windows ports of `groff' use semi-colons,
-rather than colons, to separate the directories in the lists described
-above.

-
-2.3 Macro Directories
-=====================
-
-All macro file names must be named `NAME.tmac' or `tmac.NAME' to make
-the `-mNAME' command line option work.  The `mso' request doesn't have
-this restriction; any file name can be used, and `gtroff' won't try to
-append or prepend the `tmac' string.
-
-   Macro files are kept in the "tmac directories", all of which
-constitute the "tmac path".  The elements of the search path for macro
-files are (in that order):
-
-   * The directories specified with `gtroff''s or `groff''s `-M'
-     command line option.
-
-   * The directories given in the `GROFF_TMAC_PATH' environment
-     variable.
-
-   * The current directory (only if in unsafe mode using the `-U'
-     command line switch).
-
-   * The home directory.
-
-   * A platform-dependent directory, a site-specific
-     (platform-independent) directory, and the main tmac directory; the
-     default locations are
-
-
-          /usr/local/lib/groff/site-tmac
-          /usr/local/share/groff/site-tmac
-          /usr/local/share/groff/1.18.2/tmac
-
-     assuming that the version of `groff' is 1.18.2, and the
-     installation prefix was `/usr/local'.  It is possible to fine-tune
-     those directories during the installation process.
-
-
-File: groff,  Node: Font Directories,  Next: Paper Size,  Prev: Macro Directories,  Up: Invoking groff
-
-2.4 Font Directories
-====================
-
-Basically, there is no restriction how font files for `groff' are named
-and how long font names are; however, to make the font family mechanism
-work (*note Font Families::), fonts within a family should start with
-the family name, followed by the shape.  For example, the Times family
-uses `T' for the family name and `R', `B', `I', and `BI' to indicate
-the shapes `roman', `bold', `italic', and `bold italic', respectively.
-Thus the final font names are `TR', `TB', `TI', and `TBI'.
-
-   All font files are kept in the "font directories" which constitute
-the "font path".  The file search functions will always append the
-directory `dev'NAME, where NAME is the name of the output device.
-Assuming, say, DVI output, and `/foo/bar' as a font directory, the font
-files for `grodvi' must be in `/foo/bar/devdvi'.
-
-   The elements of the search path for font files are (in that order):
-
-   * The directories specified with `gtroff''s or `groff''s `-F'
-     command line option.  All device drivers and some preprocessors
-     also have this option.
-
-   * The directories given in the `GROFF_FONT_PATH' environment
-     variable.
-
-   * A site-specific directory and the main font directory; the default
-     locations are
-
-
-          /usr/local/share/groff/site-font
-          /usr/local/share/groff/1.18.2/font
-
-     assuming that the version of `groff' is 1.18.2, and the
-     installation prefix was `/usr/local'.  It is possible to fine-tune
-     those directories during the installation process.

-
-2.5 Paper Size
-==============
-
-In groff, the page size for `gtroff' and for output devices are handled
-separately.  *Note Page Layout::, for vertical manipulation of the page
-size.  *Note Line Layout::, for horizontal changes.
-
-   A default paper size can be set in the device's `DESC' file.  Most
-output devices also have a command line option `-p' to override the
-default paper size and option `-l' to use landscape orientation.  *Note
-DESC File Format::, for a description of the `papersize' keyword which
-takes the same argument as `-p'.
-
-   A convenient shorthand to set a particular paper size for `gtroff'
-is command line option `-dpaper=SIZE'.  This defines string `paper'
-which is processed in file `papersize.tmac' (loaded in the start-up
-file `troffrc' by default).  Possible values for SIZE are the same as
-the predefined values for the `papersize' keyword (but only in
-lowercase) except `a7'-`d7'.  An appended `l' (ell) character denotes
-landscape orientation.
-
-   For example, use the following for PS output on A4 paper in landscape
-orientation:
-
-
-     groff -Tps -dpaper=a4l -P-pa4 -P-l -ms foo.ms > foo.ps
-
-   Note that it is up to the particular macro package to respect default
-page dimensions set in this way (most do).

-
-2.6 Invocation Examples
-=======================
-
-This section lists several common uses of `groff' and the corresponding
-command lines.
-
-
-     groff file
-
-This command processes `file' without a macro package or a
-preprocessor.  The output device is the default, `ps', and the output
-is sent to `stdout'.
-
-
-     groff -t -mandoc -Tascii file | less
-
-This is basically what a call to the `man' program does.  `gtroff'
-processes the manual page `file' with the `mandoc' macro file (which in
-turn either calls the `man' or the `mdoc' macro package), using the
-`tbl' preprocessor and the ASCII output device.  Finally, the `less'
-pager displays the result.
-
-
-     groff -X -m me file
-
-Preview `file' with `gxditview', using the `me' macro package.  Since
-no `-T' option is specified, use the default device (`ps').  Note that
-you can either say `-m me' or `-me'; the latter is an anachronism from
-the early days of UNIX.(1) (*note Invocation Examples-Footnote-1::)
-
-
-     groff -man -rD1 -z file
-
-Check `file' with the `man' macro package, forcing double-sided
-printing - don't produce any output.
-
-* Menu:
-
-* grog::
-
-
-File: groff,  Node: Invocation Examples-Footnotes,  Up: Invocation Examples
-
-   (1) The same is true for the other main macro packages that come
-with `groff': `man', `mdoc', `ms', `mm', and `mandoc'.  This won't work
-in general; for example, to load `trace.tmac', either `-mtrace' or
-`-m trace' must be used.
-
-
-File: groff,  Node: grog,  Prev: Invocation Examples,  Up: Invocation Examples
-
-2.6.1 `grog'
-------------
-
-`grog' reads files, guesses which of the `groff' preprocessors and/or
-macro packages are required for formatting them, and prints the `groff'
-command including those options on the standard output.  It generates
-one or more of the options `-e', `-man', `-me', `-mm', `-mom', `-ms',
-`-mdoc', `-mdoc-old', `-p', `-R', `-g', `-G', `-s', and `-t'.
-
-   A special file name `-' refers to the standard input.  Specifying no
-files also means to read the standard input.  Any specified options are
-included in the printed command.  No space is allowed between options
-and their arguments.  The only options recognized are `-C' (which is
-also passed on) to enable compatibility mode, and `-v' to print the
-version number and exit.
-
-   For example,
-
-
-     grog -Tdvi paper.ms
-
-guesses the appropriate command to print `paper.ms' and then prints it
-to the command line after adding the `-Tdvi' option.  For direct
-execution, enclose the call to `grog' in backquotes at the UNIX shell
-prompt:
-
-
-     `grog -Tdvi paper.ms` > paper.dvi
-
-As seen in the example, it is still necessary to redirect the output to
-something meaningful (i.e. either a file or a pager program like
-`less').

-3 Tutorial for Macro Users
-**************************
-
-Most users tend to use a macro package to format their papers.  This
-means that the whole breadth of `groff' is not necessary for most
-people.  This chapter covers the material needed to efficiently use a
-macro package.

-
-File: groff,  Node: Basics,  Next: Common Features,  Prev: Tutorial for Macro Users,  Up: Tutorial for Macro Users
-
-3.1 Basics
-==========
-
-This section covers some of the basic concepts necessary to understand
-how to use a macro package.(1) (*note Basics-Footnote-1::) References
-are made throughout to more detailed information, if desired.
-
-   `gtroff' reads an input file prepared by the user and outputs a
-formatted document suitable for publication or framing.  The input
-consists of text, or words to be printed, and embedded commands
-("requests" and "escapes"), which tell `gtroff' how to format the
-output.  For more detail on this, see *Note Embedded Commands::.
-
-   The word "argument" is used in this chapter to mean a word or number
-which appears on the same line as a request, and which modifies the
-meaning of that request.  For example, the request
-
-
-     .sp
-
-spaces one line, but
-
-
-     .sp 4
-
-spaces four lines.  The number 4 is an argument to the `sp' request
-which says to space four lines instead of one.  Arguments are separated
-from the request and from each other by spaces (_no_ tabs).  More
-details on this can be found in *Note Request and Macro Arguments::.
-
-   The primary function of `gtroff' is to collect words from input
-lines, fill output lines with those words, justify the right-hand margin
-by inserting extra spaces in the line, and output the result.  For
-example, the input:
-
-
-     Now is the time
-     for all good men
-     to come to the aid
-     of their party.
-     Four score and seven
-     years ago, etc.
-
-is read, packed onto output lines, and justified to produce:
-
-     Now is the time for all good men to come to the aid of their party.
-     Four score and seven years ago, etc.
-
-   Sometimes a new output line should be started even though the current
-line is not yet full; for example, at the end of a paragraph.  To do
-this it is possible to cause a "break", which starts a new output line.
-Some requests cause a break automatically, as normally do blank input
-lines and input lines beginning with a space.
-
-   Not all input lines are text to be formatted.  Some input lines are
-requests which describe how to format the text.  Requests always have a
-period (`.') or an apostrophe (`'') as the first character of the input
-line.
-
-   The text formatter also does more complex things, such as
-automatically numbering pages, skipping over page boundaries, putting
-footnotes in the correct place, and so forth.
-
-   Here are a few hints for preparing text for input to `gtroff'.
-
-   * First, keep the input lines short.  Short input lines are easier to
-     edit, and `gtroff' packs words onto longer lines anyhow.
-
-   * In keeping with this, it is helpful to begin a new line after every
-     comma or phrase, since common corrections are to add or delete
-     sentences or phrases.
-
-   * End each sentence with two spaces - or better, start each sentence
-     on a new line.  `gtroff' recognizes characters that usually end a
-     sentence, and inserts sentence space accordingly.
-
-   * Do not hyphenate words at the end of lines - `gtroff' is smart
-     enough to hyphenate words as needed, but is not smart enough to
-     take hyphens out and join a word back together.  Also, words such
-     as "mother-in-law" should not be broken over a line, since then a
-     space can occur where not wanted, such as "mother- in-law".
-
-   `gtroff' double-spaces output text automatically if you use the
-request `.ls 2'.  Reactivate single-spaced mode by typing `.ls 1'.(2)
-(*note Basics-Footnote-2::)
-
-   A number of requests allow to change the way the output looks,
-sometimes called the "layout" of the output page.  Most of these
-requests adjust the placing of "whitespace" (blank lines or spaces).
-
-   The `bp' request starts a new page, causing a line break.
-
-   The request `.sp N' leaves N lines of blank space.  N can be omitted
-(meaning skip a single line) or can be of the form Ni (for N inches) or
-Nc (for N centimeters).  For example, the input:
-
-
-     .sp 1.5i
-     My thoughts on the subject
-     .sp
-
-leaves one and a half inches of space, followed by the line "My
-thoughts on the subject", followed by a single blank line (more
-measurement units are available, see *Note Measurements::).
-
-   Text lines can be centered by using the `ce' request.  The line
-after `ce' is centered (horizontally) on the page.  To center more than
-one line, use `.ce N' (where N is the number of lines to center),
-followed by the N lines.  To center many lines without counting them,
-type:
-
-
-     .ce 1000
-     lines to center
-     .ce 0
-
-The `.ce 0' request tells `groff' to center zero more lines, in other
-words, stop centering.
-
-   All of these requests cause a break; that is, they always start a new
-line.  To start a new line without performing any other action, use
-`br'.

-3.2 Common Features
-===================
-
-`gtroff' provides very low-level operations for formatting a document.
-There are many common routine operations which are done in all
-documents.  These common operations are written into "macros" and
-collected into a "macro package".
-
-   All macro packages provide certain common capabilities which fall
-into the following categories.
-

-* Paragraphs::
-* Sections and Chapters::
-* Headers and Footers::
-* Page Layout Adjustment::

-3.2.1 Paragraphs
-----------------
-
-One of the most common and most used capability is starting a
-paragraph.  There are a number of different types of paragraphs, any of
-which can be initiated with macros supplied by the macro package.
-Normally, paragraphs start with a blank line and the first line
-indented, like the text in this manual.  There are also block style
-paragraphs, which omit the indentation:
-
-
-     Some   men  look   at  constitutions   with  sanctimonious
-     reverence, and deem them like the ark of the covenant, too
-     sacred to be touched.
-
-And there are also indented paragraphs which begin with a tag or label
-at the margin and the remaining text indented.
-
-
-     one   This is  the first paragraph.  Notice  how the first
-           line of  the resulting  paragraph lines up  with the
-           other lines in the paragraph.
-
-
-     longlabel
-           This  paragraph   had  a  long   label.   The  first
-           character of text on the first line does not line up
-           with  the  text  on  second  and  subsequent  lines,
-           although they line up with each other.
-
-   A variation of this is a bulleted list.
-
-
-     .     Bulleted lists start with a bullet.   It is possible
-           to use other glyphs instead of the bullet.  In nroff
-           mode using the ASCII character set for output, a dot
-           is used instead of a real bullet.

-3.2.2 Sections and Chapters
----------------------------
-
-Most macro packages supply some form of section headers.  The simplest
-kind is simply the heading on a line by itself in bold type.  Others
-supply automatically numbered section heading or different heading
-styles at different levels.  Some, more sophisticated, macro packages
-supply macros for starting chapters and appendices.

-
-3.2.3 Headers and Footers
--------------------------
-
-Every macro package gives some way to manipulate the "headers" and
-"footers" (also called "titles") on each page.  This is text put at the
-top and bottom of each page, respectively, which contain data like the
-current page number, the current chapter title, and so on.  Its
-appearance is not affected by the running text.  Some packages allow
-for different ones on the even and odd pages (for material printed in a
-book form).
-
-   The titles are called "three-part titles", that is, there is a
-left-justified part, a centered part, and a right-justified part.  An
-automatically generated page number may be put in any of these fields
-with the `%' character (see *Note Page Layout::, for more details).
-
-

-
-3.2.4 Page Layout
------------------
-
-Most macro packages let the user specify top and bottom margins and
-other details about the appearance of the printed pages.
-
-
-File: groff,  Node: Displays,  Next: Footnotes and Annotations,  Prev: Page Layout Adjustment,  Up: Common Features
-
-3.2.5 Displays
---------------
-
-"Displays" are sections of text to be set off from the body of the
-paper.  Major quotes, tables, and figures are types of displays, as are
-all the examples used in this document.
-
-   "Major quotes" are quotes which are several lines long, and hence
-are set in from the rest of the text without quote marks around them.
-
-   A "list" is an indented, single-spaced, unfilled display.  Lists
-should be used when the material to be printed should not be filled and
-justified like normal text, such as columns of figures or the examples
-used in this paper.
-
-   A "keep" is a display of lines which are kept on a single page if
-possible.  An example for a keep might be a diagram.  Keeps differ from
-lists in that lists may be broken over a page boundary whereas keeps are
-not.
-
-   "Floating keeps" move relative to the text.  Hence, they are good for
-things which are referred to by name, such as "See figure 3".  A
-floating keep appears at the bottom of the current page if it fits;
-otherwise, it appears at the top of the next page.  Meanwhile, the
-surrounding text `flows' around the keep, thus leaving no blank areas.
-

-File: groff,  Node: Footnotes and Annotations,  Next: Table of Contents,  Prev: Displays,  Up: Common Features
-
-3.2.6 Footnotes and Annotations
--------------------------------
-
-There are a number of requests to save text for later printing.
-
-   "Footnotes" are printed at the bottom of the current page.
-
-   "Delayed text" is very similar to a footnote except that it is
-printed when called for explicitly.  This allows a list of references to
-appear (for example) at the end of each chapter, as is the convention in
-some disciplines.
-
-   Most macro packages which supply this functionality also supply a
-means of automatically numbering either type of annotation.

-File: groff,  Node: Table of Contents,  Next: Indices,  Prev: Footnotes and Annotations,  Up: Common Features
-
-3.2.7 Table of Contents
------------------------
-
-"Tables of contents" are a type of delayed text having a tag (usually
-the page number) attached to each entry after a row of dots.  The table
-accumulates throughout the paper until printed, usually after the paper
-has ended.  Many macro packages provide the ability to have several
-tables of contents (e.g. a standard table of contents, a list of
-tables, etc).
-
-
-File: groff,  Node: Indices,  Next: Paper Formats,  Prev: Table of Contents,  Up: Common Features
-
-3.2.8 Indices
--------------
-
-While some macro packages use the term "index", none actually provide
-that functionality.  The facilities they call indices are actually more
-appropriate for tables of contents.
-
-   To produce a real index in a document, external tools like the
-`makeindex' program are necessary.
-
-
-File: groff,  Node: Paper Formats,  Next: Multiple Columns,  Prev: Indices,  Up: Common Features
-
-3.2.9 Paper Formats
--------------------
-
-Some macro packages provide stock formats for various kinds of
-documents.  Many of them provide a common format for the title and
-opening pages of a technical paper.  The `mm' macros in particular
-provide formats for letters and memoranda.
-
-

-3.2.10 Multiple Columns
------------------------
-
-Some macro packages (but not `man') provide the ability to have two or
-more columns on a page.

-
-File: groff,  Node: Font and Size Changes,  Next: Predefined Strings,  Prev: Multiple Columns,  Up: Common Features
-
-3.2.11 Font and Size Changes
-----------------------------
-
-The built-in font and size functions are not always intuitive, so all
-macro packages provide macros to make these operations simpler.
-
-
-File: groff,  Node: Predefined Strings,  Next: Preprocessor Support,  Prev: Font and Size Changes,  Up: Common Features
-
-3.2.12 Predefined Strings
--------------------------
-
-Most macro packages provide various predefined strings for a variety of
-uses; examples are sub- and superscripts, printable dates, quotes and
-various special characters.
-
-
-File: groff,  Node: Preprocessor Support,  Next: Configuration and Customization,  Prev: Predefined Strings,  Up: Common Features
-
-3.2.13 Preprocessor Support
----------------------------
-
-All macro packages provide support for various preprocessors and may
-extend their functionality.
-
-   For example, all macro packages mark tables (which are processed with
-`gtbl') by placing them between `TS' and `TE' macros.  The `ms' macro
-package has an option, `.TS H', that prints a caption at the top of a
-new page (when the table is too long to fit on a single page).
-
-
-File: groff,  Node: Configuration and Customization,  Prev: Preprocessor Support,  Up: Common Features
-
-3.2.14 Configuration and Customization
---------------------------------------
-
-Some macro packages provide means of customizing many of the details of
-how the package behaves.  This ranges from setting the default type size
-to changing the appearance of section headers.

-4 Macro Packages
-****************
-
-This chapter documents the main macro packages that come with `groff'.
-
-   Different main macro packages can't be used at the same time; for
-example
-
-
-     groff -m man foo.man -m ms bar.doc
-
-doesn't work.  Note that option arguments are processed before
-non-option arguments; the above (failing) sample is thus reordered to
-
-

-4.1 `man'
-=========
-
-This is the most popular and probably the most important macro package
-of `groff'.  It is easy to use, and a vast majority of manual pages are
-based on it.

-
-4.1.1 Options
--------------
-
-The command line format for using the `man' macros with `groff' is:
-
-
-     groff -m man [ -rLL=LENGTH ] [ -rLT=LENGTH ] [ -rFT=DIST ]
-           [ -rcR=1 ] [ -rC1 ] [ -rD1 ] [-rHY=FLAGS ]
-           [ -rPNNN ] [ -rSXX ] [ -rXNNN ]
-           [ -rIN=LENGTH ] [ -rSN=LENGTH ] [ FILES... ]
-
-It is possible to use `-man' instead of `-m man'.
-
-`-rcR=1'
-     This option (the default if a TTY output device is used) creates a
-     single, very long page instead of multiple pages.  Use `-rcR=0' to
-     disable it.
-
-`-rC1'
-     If more than one manual page is given on the command line, number
-     the pages continuously, rather than starting each at 1.
-
-`-rD1'
-     Double-sided printing.  Footers for even and odd pages are
-     formatted differently.
-
-`-rFT=DIST'
-     Set the position of the footer text to DIST.  If positive, the
-     distance is measured relative to the top of the page, otherwise it
-     is relative to the bottom.  The default is -0.5i.
-
-`-rHY=FLAGS'
-     Set hyphenation flags.  Possible values are 1 to hyphenate without
-     restrictions, 2  to not hyphenate the last word on a page, 4 to
-     not hyphenate the last two characters of a word, and 8 to not
-     hyphenate the first two characters of a word.  These values are
-     additive; the default is 14.
-
-`-rIN=LENGTH'
-     Set the body text indentation to LENGTH.  If not specified, the
-     indentation defaults to 7n (7 characters) in nroff mode and 7.2n
-     otherwise.  For nroff, this value should always be an integer
-     multiple of unit `n' to get consistent indentation.
-
-`-rLL=LENGTH'
-     Set line length to LENGTH.  If not specified, the line length is
-     set to respect any value set by a prior `ll' request (which _must_
-     be in effect when the `TH' macro is invoked), if this differs from
-     the built-in default for the formatter; otherwise it defaults to
-     78n in nroff mode (this is 78 characters per line) and 6.5i in
-     troff mode.(1) (*note Man options-Footnote-1::)
-
-`-rLT=LENGTH'
-     Set title length to LENGTH.  If not specified, the title length
-     defaults to the line length.
-
-`-rPNNN'
-     Page numbering starts with NNN rather than with 1.
-
-`-rSXX'
-     Use XX (which can be 10, 11, or 12pt) as the base document font
-     size instead of the default value of 10pt.
-
-`-rSN=LENGTH'
-     Set the indentation for sub-subheadings to LENGTH.  If not
-     specified, the indentation defaults to 3n.
-
-`-rXNNN'
-     After page NNN, number pages as NNNa, NNNb, NNNc, etc.  For
-     example, the option `-rX2' produces the following page numbers: 1,
-     2, 2a, 2b, 2c, etc.
-
-
-File: groff,  Node: Man options-Footnotes,  Up: Man options
-
-   (1) Note that the use of a `.ll LENGTH' request to initialize the
-line length, prior to use of the `TH' macro, is supported for backward
-compatibility with some versions of the `man' program.  _Always_ use the
-`-rLL=LENGTH' option, or an equivalent `.nr LL LENGTH' request, in
-preference to such a `.ll LENGTH' request.  In particular, note that in
-nroff mode, the request `.ll 65n', (with any LENGTH expression which
-evaluates equal to 65n, i.e., the formatter's default line length in
-nroff mode), will _not_ set the line length to 65n (it will be adjusted
-to the `man' macro package's default setting of 78n), whereas the use
-of the `-rLL=65n' option, or the `.nr LL 65n' request _will_ establish
-a line length of 65n.

-4.1.2 Usage
------------
-
-This section describes the available macros for manual pages.  For
-further customization, put additional macros and requests into the file
-`man.local' which is loaded immediately after the `man' package.
-
- -- Macro: .TH title section [extra1 [extra2 [extra3]]]
-     Set the title of the man page to TITLE and the section to SECTION,
-     which must have a value between 1 and 8.  The value of SECTION may
-     also have a string appended, e.g. `.pm', to indicate a specific
-     subsection of the man pages.
-
-     Both TITLE and SECTION are positioned at the left and right in the
-     header line (with SECTION in parentheses immediately appended to
-     TITLE.  EXTRA1 is positioned in the middle of the footer line.
-     EXTRA2 is positioned at the left in the footer line (or at the
-     left on even pages and at the right on odd pages if double-sided
-     printing is active).  EXTRA3 is centered in the header line.
-
-     For HTML output, headers and footers are completely suppressed.
-
-     Additionally, this macro starts a new page; the new line number
-     is 1 again (except if the `-rC1' option is given on the command
-     line) - this feature is intended only for formatting multiple man
-     pages; a single man page should contain exactly one `TH' macro at
-     the beginning of the file.
-
- -- Macro: .SH [heading]
-     Set up an unnumbered section heading sticking out to the left.
-     Prints out all the text following `SH' up to the end of the line
-     (or the text in the next line if there is no argument to `SH') in
-     bold face (or the font specified by the string `HF'), one size
-     larger than the base document size.  Additionally, the left margin
-     and the indentation for the following text is reset to its default
-     value.
-
- -- Macro: .SS [heading]
-     Set up an unnumbered (sub)section heading.  Prints out all the text
-     following `SS' up to the end of the line (or the text in the next
-     line if there is no argument to `SS') in bold face (or the font
-     specified by the string `HF'), at the same size as the base
-     document size.  Additionally, the left margin and the indentation
-     for the following text is reset to its default value.
-
- -- Macro: .TP [nnn]
-     Set up an indented paragraph with label.  The indentation is set to
-     NNN if that argument is supplied (the default unit is `n' if
-     omitted), otherwise it is set to the previous indentation value
-     specified with `TP', `IP', or `HP' (or to the default value if
-     none of them have been used yet).
-
-     The first line of text following this macro is interpreted as a
-     string to be printed flush-left, as it is appropriate for a label.
-     It is not interpreted as part of a paragraph, so there is no
-     attempt to fill the first line with text from the following input
-     lines.  Nevertheless, if the label is not as wide as the
-     indentation the paragraph starts at the same line (but indented),
-     continuing on the following lines.  If the label is wider than the
-     indentation the descriptive part of the paragraph begins on the
-     line following the label, entirely indented.  Note that neither
-     font shape nor font size of the label is set to a default value;
-     on the other hand, the rest of the text has default font settings.
-
- -- Macro: .LP
- -- Macro: .PP
- -- Macro: .P
-     These macros are mutual aliases.  Any of them causes a line break
-     at the current position, followed by a vertical space downwards by
-     the amount specified by the `PD' macro.  The font size and shape
-     are reset to the default value (10pt roman if no `-rS' option is
-     given on the command line).  Finally, the current left margin and
-     the indentation is restored.
-
- -- Macro: .IP [designator [nnn]]
-     Set up an indented paragraph, using DESIGNATOR as a tag to mark
-     its beginning.  The indentation is set to NNN if that argument is
-     supplied (default unit is `n'), otherwise it is set to the
-     previous indentation value specified with `TP', `IP', or `HP' (or
-     the default value if none of them have been used yet).  Font size
-     and face of the paragraph (but not the designator) are reset to
-     their default values.
-
-     To start an indented paragraph with a particular indentation but
-     without a designator, use `""' (two double quotes) as the first
-     argument of `IP'.
-
-     For example, to start a paragraph with bullets as the designator
-     and 4 en indentation, write
-
-
-          .IP \(bu 4
-
-
- -- Macro: .HP [nnn]
-     Set up a paragraph with hanging left indentation.  The indentation
-     is set to NNN if that argument is supplied (default unit is `n'),
-     otherwise it is set to the previous indentation value specified
-     with `TP', `IP', or `HP' (or the default value if non of them have
-     been used yet).  Font size and face are reset to their default
-     values.
-
- -- Macro: .RS [nnn]
-     Move the left margin to the right by the value NNN if specified
-     (default unit is `n'); otherwise it is set to the previous
-     indentation value specified with `TP', `IP', or `HP' (or to the
-     default value if none of them have been used yet).  The
-     indentation value is then set to the default.
-
-     Calls to the `RS' macro can be nested.
-
- -- Macro: .RE [nnn]
-     Move the left margin back to level NNN, restoring the previous left
-     margin.  If no argument is given, it moves one level back.  The
-     first level (i.e., no call to `RS' yet) has number 1, and each call
-     to `RS' increases the level by 1.
-
-   To summarize, the following macros cause a line break with the
-insertion of vertical space (which amount can be changed with the `PD'
-macro): `SH', `SS', `TP', `LP' (`PP', `P'), `IP', and `HP'.
-
-   The macros `RS' and `RE' also cause a break but do not insert
-vertical space.
-
-   Finally, the macros `SH', `SS', `LP' (`PP', `P'), and `RS' reset the
-indentation to its default value.

-4.1.3 Macros to set fonts
--------------------------
-
-The standard font is roman; the default text size is 10 point.  If
-command line option `-rS=N' is given, use Npt as the default text size.
-
- -- Macro: .SM [text]
-     Set the text on the same line or the text on the next line in a
-     font that is one point size smaller than the default font.
-
- -- Macro: .SB [text]
-     Set the text on the same line or the text on the next line in bold
-     face font, one point size smaller than the default font.
-
- -- Macro: .BI text
-     Set its arguments alternately in bold face and italic, without a
-     space between the arguments.  Thus,
-
-
-          .BI this "word and" that
-
-     produces "thisword andthat" with "this" and "that" in bold face,
-     and "word and" in italics.
-
- -- Macro: .IB text
-     Set its arguments alternately in italic and bold face, without a
-     space between the arguments.
-
- -- Macro: .RI text
-     Set its arguments alternately in roman and italic, without a space
-     between the arguments.
-
- -- Macro: .IR text
-     Set its arguments alternately in italic and roman, without a space
-     between the arguments.
-
- -- Macro: .BR text
-     Set its arguments alternately in bold face and roman, without a
-     space between the arguments.
-
- -- Macro: .RB text
-     Set its arguments alternately in roman and bold face, without a
-     space between the arguments.
-
- -- Macro: .B [text]
-     Set TEXT in bold face.  If no text is present on the line where
-     the macro is called, then the text of the next line appears in bold
-     face.
-
- -- Macro: .I [text]
-     Set TEXT in italic.  If no text is present on the line where the
-     macro is called, then the text of the next line appears in italic.

-
-4.1.4 Miscellaneous macros
---------------------------
-
-The default indentation is 7.2n in troff mode and 7n in nroff mode
-except for `grohtml' which ignores indentation.
-
- -- Macro: .DT
-     Set tabs every 0.5 inches.  Since this macro is always executed
-     during a call to the `TH' macro, it makes sense to call it only if
-     the tab positions have been changed.
-
- -- Macro: .PD [nnn]
-     Adjust the empty space before a new paragraph (or section).  The
-     optional argument gives the amount of space (default unit is `v');
-     without parameter, the value is reset to its default value (1 line
-     in nroff mode, 0.4v otherwise).
-
-     This affects the macros `SH', `SS', `TP', `LP' (as well as `PP'
-     and `P'), `IP', and `HP'.
-
-   The following two macros are included for BSD compatibility.
-
- -- Macro: .AT [system [release]]
-     Alter the footer for use with AT&T manpages.  This command exists
-     only for compatibility; don't use it.  The first argument SYSTEM
-     can be:
-
-    `3'
-          7th Edition (the default)
-
-    `4'
-          System III
-
-    `5'
-          System V
-
-     An optional second argument RELEASE to `AT' specifies the release
-     number (such as "System V Release 3").
-
- -- Macro: .UC [version]
-     Alters the footer for use with BSD manpages.  This command exists
-     only for compatibility; don't use it.  The argument can be:
-
-    `3'
-          3rd Berkeley Distribution (the default)
-
-    `4'
-          4th Berkeley Distribution
-
-    `5'
-          4.2 Berkeley Distribution
-

-     '\" WORD
-
-Note the single space character after the double quote.  WORD consists
-of letters for the needed preprocessors: `e' for `geqn', `r' for
-`grefer', `t' for `gtbl'.  Modern implementations of the `man' program
-read this first line and automatically call the right preprocessor(s).

-4.1.7 Optional `man' extensions
--------------------------------
-
-Use the file `man.local' for local extensions to the `man' macros or
-for style changes.
-
-Custom headers and footers
-..........................
-
-In groff versions 1.18.2 and later, you can specify custom headers and
-footers by redefining the following macros in `man.local'.
-
- -- Macro: .PT
-     Control the content of the headers.  Normally, the header prints
-     the command name and section number on either side, and the
-     optional fifth argument to `TH' in the center.
-
- -- Macro: .BT
-     Control the content of the footers.  Normally, the footer prints
-     the page number and the third and fourth arguments to `TH'.
-
-     Use the `FT' number register to specify the footer position.  The
-     default is -0.5i.
-
-Ultrix-specific man macros
-..........................
-
-The `groff' source distribution includes a file named `man.ultrix',
-containing macros compatible with the Ultrix variant of `man'.  Copy
-this file into `man.local' (or use the `mso' request to load it) to
-enable the following macros.
-
- -- Macro: .CT key
-     Print `<CTRL/KEY>'.
-
- -- Macro: .CW
-     Print subsequent text using the constant width (Courier) typeface.
-
- -- Macro: .Ds
-     Begin a non-filled display.
-
- -- Macro: .De
-     End a non-filled display started with `Ds'.
-
- -- Macro: .EX [indent]
-     Begins a non-filled display using the constant width (Courier)
-     typeface.  Use the optional INDENT argument to indent the display.
-
- -- Macro: .EE
-     End a non-filled display started with `EX'.
-
- -- Macro: .G [text]
-     Sets TEXT in Helvetica.  If no text is present on the line where
-     the macro is called, then the text of the next line appears in
-     Helvetica.
-
- -- Macro: .GL [text]
-     Sets TEXT in Helvetica Oblique.  If no text is present on the line
-     where the macro is called, then the text of the next line appears
-     in Helvetica Oblique.
-
- -- Macro: .HB [text]
-     Sets TEXT in Helvetica Bold.  If no text is present on the line
-     where the macro is called, then all text up to the next `HB'
-     appears in Helvetica Bold.
-
- -- Macro: .TB [text]
-     Identical to `HB'.
-
- -- Macro: .MS title sect [punct]
-     Set a manpage reference in Ultrix format.  The TITLE is in Courier
-     instead of italic.  Optional punctuation follows the section
-     number without an intervening space.
-
- -- Macro: .NT [`C'] [title]
-     Begin a note.  Print the optional title, or the word "Note",
-     centered on the page.  Text following the macro makes up the body
-     of the note, and is indented on both sides.  If the first argument
-     is `C', the body of the note is printed centered (the second
-     argument replaces the word "Note" if specified).
-
- -- Macro: .NE
-     End a note begun with `NT'.
-
- -- Macro: .PN path [punct]
-     Set the path name in constant width (Courier), followed by
-     optional punctuation.
-
- -- Macro: .Pn [punct] path [punct]
-     When called with two arguments, identical to `PN'.  When called
-     with three arguments, set the second argument in constant width
-     (Courier), bracketed by the first and third arguments in the
-     current font.
-
- -- Macro: .R
-     Switch to roman font and turn off any underlining in effect.
-
- -- Macro: .RN
-     Print the string `<RETURN>'.
-
- -- Macro: .VS [`4']
-     Start printing a change bar in the margin if the number `4' is
-     specified.  Otherwise, this macro does nothing.
-
- -- Macro: .VE
-     End printing the change bar begun by `VS'.
-
-Simple example
-..............
-
-The following example `man.local' file alters the `SH' macro to add
-some extra vertical space before printing the heading.  Headings are
-printed in Helvetica Bold.
-
-
-     .\" Make the heading fonts Helvetica
-     .ds HF HB
-     .
-     .\" Put more whitespace in front of headings.

-4.3.1 Introduction to `ms'
---------------------------
-
-The original `-ms' macros were included with AT&T `troff' as well as
-the `man' macros.  While the `man' package is intended for brief
-documents that can be read on-line as well as printed, the `ms' macros
-are suitable for longer documents that are meant to be printed rather
-than read on-line.
-
-   The `ms' macro package included with `groff' is a complete,
-bottom-up re-implementation.  Several macros (specific to AT&T or
-Berkeley) are not included, while several new commands are.  *Note
-Differences from AT&T ms::, for more information.

-
-File: groff,  Node: General ms Structure,  Next: ms Document Control Registers,  Prev: ms Intro,  Up: ms
-
-4.3.2 General structure of an `ms' document
--------------------------------------------
-
-The `ms' macro package expects a certain amount of structure, but not
-as much as packages such as `man' or `mdoc'.
-
-   The simplest documents can begin with a paragraph macro (such as
-`LP' or `PP'), and consist of text separated by paragraph macros or
-even blank lines.  Longer documents have a structure as follows:
-
-*Document type*
-     If you invoke the `RP' (report) macro on the first line of the
-     document, `groff' prints the cover page information on its own
-     page; otherwise it prints the information on the first page with
-     your document text immediately following.  Other document formats
-     found in AT&T `troff' are specific to AT&T or Berkeley, and are
-     not supported in `groff'.
-
-*Format and layout*
-     By setting number registers, you can change your document's type
-     (font and size), margins, spacing, headers and footers, and
-     footnotes.  *Note ms Document Control Registers::, for more
-     details.
-
-*Cover page*
-     A cover page consists of a title, the author's name and
-     institution, an abstract, and the date.(1) (*note General ms
-     Structure-Footnote-1::)  *Note ms Cover Page Macros::, for more
-     details.
-
-*Body*
-     Following the cover page is your document.  You can use the `ms'
-     macros to write reports, letters, books, and so forth.  The
-     package is designed for structured documents, consisting of
-     paragraphs interspersed with headings and augmented by lists,
-     footnotes, tables, and other common constructs.  *Note ms Body
-     Text::, for more details.
-
-*Table of contents*
-     Longer documents usually include a table of contents, which you can
-     invoke by placing the `TC' macro at the end of your document.  The
-     `ms' macros have minimal indexing facilities, consisting of the
-     `IX' macro, which prints an entry on standard error.  Printing the
-     table of contents at the end is necessary since `groff' is a
-     single-pass text formatter, thus it cannot determine the page
-     number of each section until that section has actually been set
-     and printed.  Since `ms' output is intended for hardcopy, you can
-     manually relocate the pages containing the table of contents
-     between the cover page and the body text after printing.

-4.3.3 Document control registers
---------------------------------
-
-The following is a list of document control number registers.  For the
-sake of consistency, set registers related to margins at the beginning
-of your document, or just after the `RP' macro.  You can set other
-registers later in your document, but you should keep them together at
-the beginning to make them easy to find and edit as necessary.
-
-Margin Settings
-...............
-
- -- Register: \n[PO]
-     Defines the page offset (i.e., the left margin).  There is no
-     explicit right margin setting; the combination of the `PO' and `LL'
-     registers implicitly define the right margin width.
-
-     Effective: next page.
-
-     Default value: 1i.
-
- -- Register: \n[LL]
-     Defines the line length (i.e., the width of the body text).
-
-     Effective: next paragraph.
-
-     Default: 6i.
-
- -- Register: \n[LT]
-     Defines the title length (i.e., the header and footer width).  This
-     is usually the same as `LL', but not necessarily.
-
-     Effective: next paragraph.
-
-     Default: 6i.
-
- -- Register: \n[HM]
-     Defines the header margin height at the top of the page.
-
-     Effective: next page.
-
-     Default: 1i.
-
- -- Register: \n[FM]
-     Defines the footer margin height at the bottom of the page.
-
-     Effective: next page.
-
-     Default: 1i.
-
-Text Settings
-.............
-
- -- Register: \n[PS]
-     Defines the point size of the body text.  If the value is larger
-     than or equal to 1000, divide it by 1000 to get a fractional point
-     size.  For example, `.nr PS 10250' sets the document's point size
-     to 10.25p.
-
-     Effective: next paragraph.
-
-     Default: 10p.
-
- -- Register: \n[VS]
-     Defines the space between lines (line height plus leading).  If the
-     value is larger than or equal to 1000, divide it by 1000 to get a
-     fractional point size.  Due to backwards compatibility, `VS' must
-     be smaller than 40000 (this is 40.0p).
-
-     Effective: next paragraph.
-
-     Default: 12p.
-
- -- Register: \n[PSINCR]
-     Defines an increment in point size, which will be applied to
-     section headings at nesting levels below the value specified in
-     `GROWPS'.  The value of `PSINCR' should be specified in points,
-     with the p scaling factor, and may include a fractional component;
-     for example, `.nr PSINCR 1.5p' sets a point size increment of 1.5p.
-
-     Effective: next section heading.
-
-     Default: 1p.
-
- -- Register: \n[GROWPS]
-     Defines the heading level below which the point size increment set
-     by `PSINCR' becomes effective.  Section headings at and above the
-     level specified by `GROWPS' will be printed at the point size set
-     by `PS'; for each level below the value of `GROWPS', the point
-     size will be increased in steps equal to the value of `PSINCR'.
-     Setting `GROWPS' to any value less than 2 disables the incremental
-     heading size feature.
-
-     Effective: next section heading.
-
-     Default: 0.
-
- -- Register: \n[HY]
-     Defines the hyphenation level.  `HY' sets safely the value of the
-     low-level `hy' register.  Setting the value of `HY' to 0 is
-     equivalent to using the `nh' request.
-
-     Effective: next paragraph.
-
-     Default: 14.
-
- -- Register: \n[FAM]
-     Defines the font family used to typeset the document.
-
-     Effective: next paragraph.
-
-     Default: as defined in the output device.
-
-Paragraph Settings
-..................
-
- -- Register: \n[PI]
-     Defines the initial indentation of a (`PP' macro) paragraph.
-
-     Effective: next paragraph.
-
-     Default: 5n.
-
- -- Register: \n[PD]
-     Defines the space between paragraphs.
-
-     Effective: next paragraph.
-
-     Default: 0.3v.
-
- -- Register: \n[QI]
-     Defines the indentation on both sides of a quoted (`QP' macro)
-     paragraph.
-
-     Effective: next paragraph.
-
-     Default: 5n.
-
- -- Register: \n[PORPHANS]
-     Defines the minimum number of initial lines of any paragraph which
-     should be kept together, to avoid orphan lines at the bottom of a
-     page.  If a new paragraph is started close to the bottom of a page,
-     and there is insufficient space to accommodate `PORPHANS' lines
-     before an automatic page break, then the page break will be forced,
-     before the start of the paragraph.
-
-     Effective: next paragraph.
-
-     Default: 1.
-
- -- Register: \n[HORPHANS]
-     Defines the minimum number of lines of the following paragraph
-     which should be kept together with any section heading introduced
-     by the `NH' or `SH' macros.  If a section heading is placed close
-     to the bottom of a page, and there is insufficient space to
-     accommodate both the heading and at least `HORPHANS' lines of the
-     following paragraph, before an automatic page break, then the page
-     break will be forced before the heading.
-
-     Effective: next paragraph.
-
-     Default: 1.
-
-Footnote Settings
-.................
-
- -- Register: \n[FL]
-     Defines the length of a footnote.
-
-     Effective: next footnote.
-
-     Default: `\n[LL]' * 5 / 6.
-
- -- Register: \n[FI]
-     Defines the footnote indentation.
-
-     Effective: next footnote.
-
-     Default: 2n.
-
- -- Register: \n[FF]
-     The footnote format:
-    `0'
-          Print the footnote number as a superscript; indent the
-          footnote (default).
-
-    `1'
-          Print the number followed by a period (like 1.) and indent the
-          footnote.
-
-    `2'
-          Like 1, without an indentation.
-
-    `3'
-          Like 1, but print the footnote number as a hanging paragraph.
-
-     Effective: next footnote.
-
-     Default: 0.
-
- -- Register: \n[FPS]
-     Defines the footnote point size.  If the value is larger than or
-     equal to 1000, divide it by 1000 to get a fractional point size.
-
-     Effective: next footnote.
-
-     Default: `\n[PS]' - 2.
-
- -- Register: \n[FVS]
-     Defines the footnote vertical spacing.  If the value is larger
-     than or equal to 1000, divide it by 1000 to get a fractional point
-     size.
-
-     Effective: next footnote.
-
-     Default: `\n[FPS]' + 2.
-
- -- Register: \n[FPD]
-     Defines the footnote paragraph spacing.
-
-     Effective: next footnote.
-
-     Default: `\n[PD]' / 2.

-4.3.4 Cover page macros
------------------------
-
-Use the following macros to create a cover page for your document in
-the order shown.
-
- -- Macro: .RP [`no']
-     Specifies the report format for your document.  The report format
-     creates a separate cover page.  The default action (no `RP' macro)
-     is to print a subset of the cover page on page 1 of your document.
-
-     If you use the word `no' as an optional argument, `groff' prints a
-     title page but does not repeat any of the title page information
-     (title, author, abstract, etc.) on page 1 of the document.
-
- -- Macro: .P1
-     (P-one) Prints the header on page 1.  The default is to suppress
-     the header.
-
- -- Macro: .DA [...]
-     (optional) Prints the current date, or the arguments to the macro
-     if any, on the title page (if specified) and in the footers.  This
-     is the default for `nroff'.
-
- -- Macro: .ND [...]
-     (optional) Prints the current date, or the arguments to the macro
-     if any, on the title page (if specified) but not in the footers.
-     This is the default for `troff'.
-
- -- Macro: .TL
-     Specifies the document title.  `groff' collects text following the
-     `TL' macro into the title, until reaching the author name or
-     abstract.
-
- -- Macro: .AU
-     Specifies the author's name, which appears on the line (or lines)
-     immediately following.  You can specify multiple authors as
-     follows:
-
-
-          .AU
-          John Doe
-          .AI
-          University of West Bumblefuzz
-          .AU
-          Martha Buck
-          .AI
-          Monolithic Corporation
-
-          ...
-
-
- -- Macro: .AI
-     Specifies the author's institution.  You can specify multiple
-     institutions in the same way that you specify multiple authors.
-
- -- Macro: .AB [`no']
-     Begins the abstract.  The default is to print the word ABSTRACT,
-     centered and in italics, above the text of the abstract.  The word
-     `no' as an optional argument suppresses this heading.
-
- -- Macro: .AE
-     Ends the abstract.

- -- Macro: .LP
-     Sets a paragraph with an initial indentation.
-
- -- Macro: .QP
-     Sets a paragraph that is indented at both left and right margins.
-     The effect is identical to the HTML `<BLOCKQUOTE>' element.  The
-     next paragraph or heading returns margins to normal.
-
- -- Macro: .XP
-     Sets a paragraph whose lines are indented, except for the first
-     line.  This is a Berkeley extension.

-4.3.5.2 Headings
-................
-
-Use headings to create a hierarchical structure for your document.  The
-`ms' macros print headings in *bold*, using the same font family and
-point size as the body text.
-
-   The following describes the heading macros:
-
- -- Macro: .NH curr-level
- -- Macro: .NH S level0 ...
-     Numbered heading.  The argument is either a numeric argument to
-     indicate the level of the heading, or the letter `S' followed by
-     numeric arguments to set the heading level explicitly.
-
-     If you specify heading levels out of sequence, such as invoking
-     `.NH 3' after `.NH 1', `groff' prints a warning on standard error.
-
- -- String: \*[SN]
- -- String: \*[SN-DOT]
- -- String: \*[SN-NO-DOT]
-     After invocation of `NH', the assigned section number is made
-     available in the strings `SN-DOT' (exactly as it appears in the
-     printed section heading) and `SN-NO-DOT' (with the final period
-     omitted).  The string `SN' is also defined, as an alias for
-     `SN-DOT'; if preferred, you may redefine it as an alias for
-     `SN-NO-DOT', by including the initialization
-
-
-          .ds SN-NO-DOT
-          .als SN SN-NO-DOT
-
-     *before* your first use of `NH', or simply
-
-

-
- -- Macro: .SH [match-level]
-     Unnumbered subheading.
-
-     The optional MATCH-LEVEL argument is a GNU extension.  It is a
-     number indicating the level of the heading, in a manner analogous
-     to the CURR-LEVEL argument to `.NH'.  Its purpose is to match the
-     point size, at which the heading is printed, to the size of a
-     numbered heading at the same level, when the `GROWPS' and `PSINCR'
-     heading size adjustment mechanism is in effect.  *Note ms Document

-
-   The `HORPHANS' register (*note ms Document Control Registers::)

-4.3.5.3 Highlighting
-....................
-
-The `ms' macros provide a variety of methods to highlight or emphasize
-text:
-
- -- Macro: .B [txt [post [pre]]]
-     Sets its first argument in *bold type*.  If you specify a second
-     argument, `groff' prints it in the previous font after the bold
-     text, with no intervening space (this allows you to set
-     punctuation after the highlighted text without highlighting the
-     punctuation).  Similarly, it prints the third argument (if any) in
-     the previous font *before* the first argument.  For example,
-
-
-          .B foo ) (
-
-     prints (*foo*).
-
-     If you give this macro no arguments, `groff' prints all text
-     following in bold until the next highlighting, paragraph, or
-     heading macro.
-
- -- Macro: .R [txt [post [pre]]]
-     Sets its first argument in roman (or regular) type.  It operates
-     similarly to the `B' macro otherwise.
-
- -- Macro: .I [txt [post [pre]]]
-     Sets its first argument in _italic type_.  It operates similarly
-     to the `B' macro otherwise.
-
- -- Macro: .CW [txt [post [pre]]]
-     Sets its first argument in a `constant width face'.  It operates
-     similarly to the `B' macro otherwise.
-
- -- Macro: .BI [txt [post [pre]]]
-     Sets its first argument in bold italic type.  It operates
-     similarly to the `B' macro otherwise.
-
- -- Macro: .BX [txt]
-     Prints its argument and draws a box around it.  If you want to box
-     a string that contains spaces, use a digit-width space (`\0').
-
- -- Macro: .UL [txt [post]]
-     Prints its first argument with an underline.  If you specify a
-     second argument, `groff' prints it in the previous font after the
-     underlined text, with no intervening space.
-
- -- Macro: .LG
-     Prints all text following in larger type (two points larger than
-     the current point size) until the next font size, highlighting,
-     paragraph, or heading macro.  You can specify this macro multiple
-     times to enlarge the point size as needed.
-
- -- Macro: .SM
-     Prints all text following in smaller type (two points smaller than
-     the current point size) until the next type size, highlighting,
-     paragraph, or heading macro.  You can specify this macro multiple
-     times to reduce the point size as needed.
-
- -- Macro: .NL
-     Prints all text following in the normal point size (that is, the
-     value of the `PS' register).
-
- -- String: \*[{]
- -- String: \*[}]
-     Text enclosed with `\*{' and `\*}' is printed as a superscript.

-4.3.5.4 Lists
-.............
-
-The `IP' macro handles duties for all lists.
-
- -- Macro: .IP [marker [width]]
-     The MARKER is usually a bullet glyph (`\[bu]') for unordered
-     lists, a number (or auto-incrementing number register) for
-     numbered lists, or a word or phrase for indented (glossary-style)
-     lists.
-
-     The WIDTH specifies the indentation for the body of each list
-     item; its default unit is `n'.  Once specified, the indentation
-     remains the same for all list items in the document until specified
-     again.
-
-     The `PORPHANS' register (*note ms Document Control Registers::)
-     operates in conjunction with the `IP' macro, to inhibit the
-     printing of orphaned list markers at the bottom of any page.
-
-   The following is an example of a bulleted list.  
-
-
-     A bulleted list:
-     .IP \[bu] 2

-

-
-     guns  Firearms, preferably large-caliber.
-
-     money
-           Gotta pay for those lawyers and guns!
-
-   In the last example, the `IP' macro places the definition on the
-same line as the term if it has enough space; otherwise, it breaks to
-the next line and starts the definition below the term.  This may or
-may not be the effect you want, especially if some of the definitions
-break and some do not.  The following examples show two possible ways
-to force a break.
-
-   The first workaround uses the `br' request to force a break after
-printing the term or label.
-
-

-     .IP lawyers 0.4i

-     .IP guns
-     .br
-     Firearms, preferably large-caliber.
-     .IP money
-     Gotta pay for those lawyers and guns!
-
-   The second workaround uses the `\p' escape to force the break.  Note
-the space following the escape; this is important.  If you omit the
-space, `groff' prints the first word on the same line as the term or
-label (if it fits) *then* breaks the line.

-
-In many situations, you may need to indentation a section of text while
-still wrapping and filling.  *Note Lists in ms::, for an example of
-nested lists.
-
- -- Macro: .RS
- -- Macro: .RE
-     These macros begin and end an indented section.  The `PI' register
-     controls the amount of indentation, allowing the indented text to
-     line up under hanging and indented paragraphs.

-.................
-
-Use the `ta' request to define tab stops as needed.  *Note Tabs and
-Fields::.
-
- -- Macro: .TA
-     Use this macro to reset the tab stops to the default for `ms'
-     (every 5n).  You can redefine the `TA' macro to create a different
-     set of default tab stops.

-
-4.3.5.7 Displays and keeps
-..........................
-
-Use displays to show text-based examples or figures (such as code
-listings).
-
-   Displays turn off filling, so lines of code are displayed as-is
-without inserting `br' requests in between each line.  Displays can be
-"kept" on a single page, or allowed to break across pages.
-
- -- Macro: .DS L
- -- Macro: .LD
- -- Macro: .DE
-     Left-justified display.  The `.DS L' call generates a page break,
-     if necessary, to keep the entire display on one page.  The `LD'
-     macro allows the display to break across pages.  The `DE' macro
-     ends the display.
-
- -- Macro: .DS I
- -- Macro: .ID
- -- Macro: .DE
-     Indents the display as defined by the `DI' register.  The `.DS I'
-     call generates a page break, if necessary, to keep the entire
-     display on one page.  The `ID' macro allows the display to break
-     across pages.  The `DE' macro ends the display.
-
- -- Macro: .DS B
- -- Macro: .BD
- -- Macro: .DE
-     Sets a block-centered display: the entire display is
-     left-justified, but indented so that the longest line in the
-     display is centered on the page.  The `.DS B' call generates a
-     page break, if necessary, to keep the entire display on one page.
-     The `BD' macro allows the display to break across pages.  The `DE'
-     macro ends the display.
-
- -- Macro: .DS C
- -- Macro: .CD
- -- Macro: .DE
-     Sets a centered display: each line in the display is centered.  The
-     `.DS C' call generates a page break, if necessary, to keep the
-     entire display on one page.  The `CD' macro allows the display to
-     break across pages.  The `DE' macro ends the display.
-
- -- Macro: .DS R
- -- Macro: .RD
- -- Macro: .DE
-     Right-justifies each line in the display.  The `.DS R' call
-     generates a page break, if necessary, to keep the entire display on
-     one page.  The `RD' macro allows the display to break across
-     pages.  The `DE' macro ends the display.
-
- -- Macro: .Ds
- -- Macro: .De
-     These two macros were formerly provided as aliases for `DS' and
-     `DE', respectively.  They have been removed, and should no longer
-     be used.  The original implementations of `DS' and `DE' are
-     retained, and should be used instead.  X11 documents which actually
-     use `Ds' and `De' always load a specific macro file from the X11
-     distribution (`macros.t') which provides proper definitions for
-     the two macros.
-
-   On occasion, you may want to "keep" other text together on a page.
-For example, you may want to keep two paragraphs together, or a
-paragraph that refers to a table (or list, or other item) immediately
-following.  The `ms' macros provide the `KS' and `KE' macros for this
-purpose.
-
- -- Macro: .KS
- -- Macro: .KE
-     The `KS' macro begins a block of text to be kept on a single page,
-     and the `KE' macro ends the block.
-
- -- Macro: .KF
- -- Macro: .KE
-     Specifies a "floating keep"; if the keep cannot fit on the current
-     page, `groff' holds the contents of the keep and allows text
-     following the keep (in the source file) to fill in the remainder of
-     the current page.  When the page breaks, whether by an explicit
-     `bp' request or by reaching the end of the page, `groff' prints
-     the floating keep at the top of the new page.  This is useful for
-     printing large graphics or tables that do not need to appear
-     exactly where specified.
-
-   You can also use the `ne' request to force a page break if there is
-not enough vertical space remaining on the page.
-
-   Use the following macros to draw a box around a section of text (such
-as a display).
-
- -- Macro: .B1
- -- Macro: .B2
-     Marks the beginning and ending of text that is to have a box drawn
-     around it.  The `B1' macro begins the box; the `B2' macro ends it.
-     Text in the box is automatically placed in a diversion (keep).

-4.3.5.8 Tables, figures, equations, and references
-..................................................
-
-The `ms' macros support the standard `groff' preprocessors: `tbl',
-`pic', `eqn', and `refer'.  You mark text meant for preprocessors by
-enclosing it in pairs of tags as follows.
-
- -- Macro: .TS [`H']
- -- Macro: .TE
-     Denotes a table, to be processed by the `tbl' preprocessor.  The
-     optional argument `H' to `TS' instructs `groff' to create a
-     running header with the information up to the `TH' macro.  `groff'
-     prints the header at the beginning of the table; if the table runs
-     onto another page, `groff' prints the header on the next page as
-     well.
-
- -- Macro: .PS
- -- Macro: .PE
-     Denotes a graphic, to be processed by the `pic' preprocessor.  You
-     can create a `pic' file by hand, using the AT&T `pic' manual
-     available on the Web as a reference, or by using a graphics
-     program such as `xfig'.
-
- -- Macro: .EQ [align]
- -- Macro: .EN
-     Denotes an equation, to be processed by the `eqn' preprocessor.
-     The optional ALIGN argument can be `C', `L', or `I' to center (the
-     default), left-justify, or indent the equation.
-
- -- Macro: .[
- -- Macro: .]
-     Denotes a reference, to be processed by the `refer' preprocessor.
-     The GNU `refer(1)' man page provides a comprehensive reference to
-     the preprocessor and the format of the bibliographic database.

-4.3.5.10 Footnotes
-..................
-
-The `ms' macro package has a flexible footnote system.  You can specify
-either numbered footnotes or symbolic footnotes (that is, using a
-marker such as a dagger symbol).
-
- -- String: \*[*]
-     Specifies the location of a numbered footnote marker in the text.
-
- -- Macro: .FS
- -- Macro: .FE
-     Specifies the text of the footnote.  The default action is to
-     create a numbered footnote; you can create a symbolic footnote by
-     specifying a "mark" glyph (such as `\[dg]' for the dagger glyph)
-     in the body text and as an argument to the `FS' macro, followed by
-     the text of the footnote and the `FE' macro.
-
-   You can control how `groff' prints footnote numbers by changing the
-value of the `FF' register.  *Note ms Document Control Registers::.
-
-   Footnotes can be safely used within keeps and displays, but you
-should avoid using numbered footnotes within floating keeps.  You can
-set a second `\**' marker between a `\**' and its corresponding `.FS'
-entry; as long as each `FS' macro occurs _after_ the corresponding
-`\**' and the occurrences of `.FS' are in the same order as the
-corresponding occurrences of `\**'.

-4.3.6.1 Headers and footers
-...........................
-
-For documents that do not distinguish between odd and even pages, set
-the following strings:
-
- -- String: \*[LH]
- -- String: \*[CH]
- -- String: \*[RH]
-     Sets the left, center, and right headers.
-
- -- String: \*[LF]
- -- String: \*[CF]
- -- String: \*[RF]
-     Sets the left, center, and right footers.
-
-   For documents that need different information printed in the even and
-odd pages, use the following macros:
-
- -- Macro: .OH 'left'center'right'
- -- Macro: .EH 'left'center'right'
- -- Macro: .OF 'left'center'right'
- -- Macro: .EF 'left'center'right'
-     The `OH' and `EH' macros define headers for the odd and even
-     pages; the `OF' and `EF' macros define footers for the odd and
-     even pages.  This is more flexible than defining the individual
-     strings.
-
-     You can replace the quote (`'') marks with any character not
-     appearing in the header or footer text.

-4.3.6.3 Multiple columns
-........................
-
-The `ms' macros can set text in as many columns as will reasonably fit
-on the page.  The following macros are available; all of them force a
-page break if a multi-column mode is already set.  However, if the
-current mode is single-column, starting a multi-column mode does _not_
-force a page break.
-
- -- Macro: .1C
-     Single-column mode.
-
- -- Macro: .2C
-     Two-column mode.
-
- -- Macro: .MC [width [gutter]]
-     Multi-column mode.  If you specify no arguments, it is equivalent
-     to the `2C' macro.  Otherwise, WIDTH is the width of each column
-     and GUTTER is the space between columns.  The `MINGW' number
-     register controls the default gutter width.

-
-4.3.6.4 Creating a table of contents
-....................................
-
-The facilities in the `ms' macro package for creating a table of
-contents are semi-automated at best.  Assuming that you want the table
-of contents to consist of the document's headings, you need to repeat
-those headings wrapped in `XS' and `XE' macros.
-
- -- Macro: .XS [page]
- -- Macro: .XA [page]
- -- Macro: .XE
-     These macros define a table of contents or an individual entry in
-     the table of contents, depending on their use.  The macros are very
-     simple; they cannot indent a heading based on its level.  The
-     easiest way to work around this is to add tabs to the table of
-     contents string.  The following is an example:
-
-
-          .NH 1
-          Introduction
-          .XS
-          Introduction
-          .XE
-          .LP
-          ...
-          .CW
-          .NH 2
-          Methodology
-          .XS
-          Methodology
-          .XE
-          .LP
-          ...
-
-     You can manually create a table of contents by beginning with the
-     `XS' macro for the first entry, specifying the page number for
-     that entry as the argument to `XS'.  Add subsequent entries using
-     the `XA' macro, specifying the page number for that entry as the
-     argument to `XA'.  The following is an example:
-
-
-          .XS 1
-          Introduction
-          .XA 2
-          A Brief History of the Universe
-          .XA 729
-          Details of Galactic Formation
-          ...
-          .XE
-
-
- -- Macro: .TC [`no']
-     Prints the table of contents on a new page, setting the page number
-     to *i* (Roman lowercase numeral one).  You should usually place
-     this macro at the end of the file, since `groff' is a single-pass
-     formatter and can only print what has been collected up to the
-     point that the `TC' macro appears.
-
-     The optional argument `no' suppresses printing the title specified
-     by the string register `TOC'.
-
- -- Macro: .PX [`no']
-     Prints the table of contents on a new page, using the current page
-     numbering sequence.  Use this macro to print a manually-generated
-     table of contents at the beginning of your document.
-
-     The optional argument `no' suppresses printing the title specified
-     by the string register `TOC'.
-
-   The `Groff and Friends HOWTO' includes a `sed' script that
-automatically inserts `XS' and `XE' macro entries after each heading in
-a document.
-
-   Altering the `NH' macro to automatically build the table of contents
-is perhaps initially more difficult, but would save a great deal of
-time in the long run if you use `ms' regularly.

-4.3.7 Differences from AT&T `ms'
---------------------------------
-
-This section lists the (minor) differences between the `groff -ms'
-macros and AT&T `troff -ms' macros.
-
-   * The internals of `groff -ms' differ from the internals of AT&T
-     `troff -ms'.  Documents that depend upon implementation details of
-     AT&T `troff -ms' may not format properly with `groff -ms'.
-
-   * The general error-handling policy of `groff -ms' is to detect and
-     report errors, rather than silently to ignore them.
-
-   * `groff -ms' does not work in compatibility mode (this is, with the
-     `-C' option).
-
-   * There is no special support for typewriter-like devices.
-
-   * `groff -ms' does not provide cut marks.
-
-   * Multiple line spacing is not supported.  Use a larger vertical
-     spacing instead.
-
-   * Some UNIX `ms' documentation says that the `CW' and `GW' number
-     registers can be used to control the column width and gutter
-     width, respectively.  These number registers are not used in
-     `groff -ms'.
-
-   * Macros that cause a reset (paragraphs, headings, etc.) may change
-     the indentation.  Macros that change the indentation do not
-     increment or decrement the indentation, but rather set it
-     absolutely.  This can cause problems for documents that define
-     additional macros of their own.  The solution is to use not the
-     `in' request but instead the `RS' and `RE' macros.
-
-   * To make `groff -ms' use the default page offset (which also
-     specifies the left margin), the `PO' register must stay undefined
-     until the first `-ms' macro is evaluated.  This implies that `PO'
-     should not be used early in the document, unless it is changed
-     also: Remember that accessing an undefined register automatically
-     defines it.
-
- -- Register: \n[GS]
-     This number register is set to 1 by the `groff -ms' macros, but it
-     is not used by the `AT&T' `troff -ms' macros.  Documents that need
-     to determine whether they are being formatted with `AT&T' `troff
-     -ms' or `groff -ms' should use this number register.

-4.3.7.2 `groff' macros not appearing in AT&T `troff'
-....................................................
-
-The `groff -ms' macros have a few minor extensions compared to the AT&T
-`troff -ms' macros.
-
- -- Macro: .AM
-     Improved accent marks.  *Note ms Strings and Special Characters::,
-     for details.
-
- -- Macro: .DS I
-     Indented display.  The default behavior of AT&T `troff -ms' was to
-     indent; the `groff' default prints displays flush left with the
-     body text.
-
- -- Macro: .CW
-     Print text in `constant width' (Courier) font.
-
- -- Macro: .IX
-     Indexing term (printed on standard error).  You can write a script
-     to capture and process an index generated in this manner.
-
-   The following additional number registers appear in `groff -ms':
-
- -- Register: \n[MINGW]
-     Specifies a minimum space between columns (for multi-column
-     output); this takes the place of the `GW' register that was
-     documented but apparently not implemented in AT&T `troff'.
-
-   Several new string registers are available as well.  You can change
-these to handle (for example) the local language.  *Note ms Strings and
-Special Characters::, for details.
-
-
-File: groff,  Node: Naming Conventions,  Prev: Differences from AT&T ms,  Up: ms
-
-4.3.8 Naming Conventions
-------------------------
-
-The following conventions are used for names of macros, strings and
-number registers.  External names available to documents that use the
-`groff -ms' macros contain only uppercase letters and digits.
-
-   Internally the macros are divided into modules; naming conventions
-are as follows:
-
-   * Names used only within one module are of the form MODULE`*'NAME.
-
-   * Names used outside the module in which they are defined are of the
-     form MODULE`@'NAME.
-
-   * Names associated with a particular environment are of the form
-     ENVIRONMENT`:'NAME; these are used only within the `par' module.
-
-   * NAME does not have a module prefix.
-
-   * Constructed names used to implement arrays are of the form
-     ARRAY`!'INDEX.
-
-   Thus the groff ms macros reserve the following names:
-
-   * Names containing the characters `*', `@', and `:'.
-
-   * Names containing only uppercase letters and digits.

-5.1 Text
-========
-
-`gtroff' input files contain text with control commands interspersed
-throughout.  But, even without control codes, `gtroff' still does
-several things with the input text:
-
-   * filling and adjusting
-
-   * adding additional space after sentences
-
-   * hyphenating
-
-   * inserting implicit line breaks

-File: groff,  Node: Filling and Adjusting,  Next: Hyphenation,  Prev: Text,  Up: Text
-
-5.1.1 Filling and Adjusting
----------------------------
-
-When `gtroff' reads text, it collects words from the input and fits as
-many of them together on one output line as it can.  This is known as
-"filling".
-
-   Once `gtroff' has a "filled" line, it tries to "adjust" it.  This
-means it widens the spacing between words until the text reaches the
-right margin (in the default adjustment mode).  Extra spaces between
-words are preserved, but spaces at the end of lines are ignored.
-Spaces at the front of a line cause a "break" (breaks are explained in
-*Note Implicit Line Breaks::).
-
-   *Note Manipulating Filling and Adjusting::.
-
-
-File: groff,  Node: Hyphenation,  Next: Sentences,  Prev: Filling and Adjusting,  Up: Text
-
-5.1.2 Hyphenation
------------------
-
-Since the odds are not great for finding a set of words, for every
-output line, which fit nicely on a line without inserting excessive
-amounts of space between words, `gtroff' hyphenates words so that it
-can justify lines without inserting too much space between words.  It
-uses an internal hyphenation algorithm (a simplified version of the
-algorithm used within TeX) to indicate which words can be hyphenated
-and how to do so.  When a word is hyphenated, the first part of the
-word is added to the current filled line being output (with an attached
-hyphen), and the other portion is added to the next line to be filled.
-
-   *Note Manipulating Hyphenation::.
-
-
-File: groff,  Node: Sentences,  Next: Tab Stops,  Prev: Hyphenation,  Up: Text
-
-5.1.3 Sentences
----------------
-
-Although it is often debated, some typesetting rules say there should be
-different amounts of space after various punctuation marks.  For
-example, the `Chicago typsetting manual' says that a period at the end
-of a sentence should have twice as much space following it as would a
-comma or a period as part of an abbreviation.
-
-   `gtroff' does this by flagging certain characters (normally `!',
-`?', and `.') as "end-of-sentence" characters.  When `gtroff'
-encounters one of these characters at the end of a line, it appends a
-normal space followed by a "sentence space" in the formatted output.
-(This justifies one of the conventions mentioned in *Note Input
-Conventions::.)
-
-   In addition, the following characters and symbols are treated
-transparently while handling end-of-sentence characters: `"', `'', `)',
-`]', `*', `\[dg]', and `\[rq]'.
-
-   See the `cflags' request in *Note Using Symbols::, for more details.
-
-   To prevent the insertion of extra space after an end-of-sentence
-character (at the end of a line), append `\&'.
-
-
-File: groff,  Node: Tab Stops,  Next: Implicit Line Breaks,  Prev: Sentences,  Up: Text
-
-5.1.4 Tab Stops
----------------
-
-`gtroff' translates "tabulator characters", also called "tabs"
-(normally code point ASCII `0x09' or EBCDIC `0x05'), in the input into
-movements to the next tabulator stop.  These tab stops are initially
-located every half inch across the page.  Using this, simple tables can
-be made easily.  However, it can often be deceptive as the appearance
-(and width) of the text on a terminal and the results from `gtroff' can
-vary greatly.
-
-   Also, a possible sticking point is that lines beginning with tab
-characters are still filled, again producing unexpected results.  For
-example, the following input
-
-           1          2          3
-                      4          5
-
-produces
-
-           1          2          3                     4          5
-
-   *Note Tabs and Fields::.
-
-
-File: groff,  Node: Implicit Line Breaks,  Next: Input Conventions,  Prev: Tab Stops,  Up: Text
-
-5.1.5 Implicit Line Breaks
---------------------------
-
-An important concept in `gtroff' is the "break".  When a break occurs,
-`gtroff' outputs the partially filled line (unjustified), and resumes
-collecting and filling text on the next output line.
-
-   There are several ways to cause a break in `gtroff'.  A blank line
-not only causes a break, but it also outputs a one-line vertical space
-(effectively a blank line).  Note that this behaviour can be modified
-with the blank line macro request `blm'.  *Note Blank Line Traps::.
-
-   A line that begins with a space causes a break and the space is
-output at the beginning of the next line.  Note that this space isn't
-adjusted, even in fill mode.
-
-   The end of file also causes a break - otherwise the last line of the
-document may vanish!
-
-   Certain requests also cause breaks, implicitly or explicitly.  This
-is discussed in *Note Manipulating Filling and Adjusting::.
-
-
-File: groff,  Node: Input Conventions,  Next: Input Encodings,  Prev: Implicit Line Breaks,  Up: Text
-
-5.1.6 Input Conventions
------------------------
-
-Since `gtroff' does filling automatically, it is traditional in `groff'
-not to try and type things in as nicely formatted paragraphs.  These
-are some conventions commonly used when typing `gtroff' text:
-
-   * Break lines after punctuation, particularly at the end of a
-     sentence and in other logical places.  Keep separate phrases on
-     lines by themselves, as entire phrases are often added or deleted
-     when editing.
-
-   * Try to keep lines less than 40-60 characters, to allow space for
-     inserting more text.
-
-   * Do not try to do any formatting in a WYSIWYG manner (i.e., don't
-     try using spaces to get proper indentation).
-
-
-File: groff,  Node: Input Encodings,  Prev: Input Conventions,  Up: Text
-
-5.1.7 Input Encodings
----------------------
-
-Currently, the following input encodings are available.
-
-cp1047
-     This input encoding works only on EBCDIC platforms (and vice
-     versa, the other input encodings don't work with EBCDIC); the file
-     `cp1047.tmac' is by default loaded at start-up.
-
-latin-1
-     This is the default input encoding on non-EBCDIC platforms; the
-     file `latin1.tmac' is loaded at start-up.
-
-latin-2
-     To use this encoding, either say `.mso latin2.tmac' at the very
-     beginning of your document or use `-mlatin2' as a command line
-     argument for `groff'.
-
-latin-9 (latin-0)
-     This encoding is intended (at least in Europe) to replace latin-1
-     encoding.  The main difference to latin-1 is that latin-9 contains
-     the Euro character.  To use this encoding, either say
-     `.mso latin9.tmac' at the very beginning of your document or use
-     `-mlatin9' as a command line argument for `groff'.
-
-   Note that it can happen that some input encoding characters are not
-available for a particular output device.  For example, saying
-
-
-     groff -Tlatin1 -mlatin9 ...
-
-will fail if you use the Euro character in the input.  Usually, this
-limitation is present only for devices which have a limited set of
-output glyphs (e.g. `-Tascii' and `-Tlatin1'); for other devices it is
-usually sufficient to install proper fonts which contain the necessary
-glyphs.
-
-   Due to the importance of the Euro glyph in Europe, the groff package
-now comes with a POSTSCRIPT font called `freeeuro.pfa' which provides
-various glyph shapes for the Euro.  With other words, latin-9 encoding
-is supported for the `-Tps' device out of the box (latin-2 isn't).
-
-   By its very nature, `-Tutf8' supports all input encodings; `-Tdvi'
-has support for both latin-2 and latin-9 if the command line `-mec' is
-used also to load the file `ec.tmac' (which flips to the EC fonts).

-5.2 Measurements
-================
-
-`gtroff' (like many other programs) requires numeric parameters to
-specify various measurements.  Most numeric parameters(1) (*note
-Measurements-Footnote-1::) may have a "measurement unit" attached.
-These units are specified as a single character which immediately
-follows the number or expression.  Each of these units are understood,
-by `gtroff', to be a multiple of its "basic unit".  So, whenever a
-different measurement unit is specified `gtroff' converts this into its
-"basic units".  This basic unit, represented by a `u', is a device
-dependent measurement which is quite small, ranging from 1/75th to
-1/72000th of an inch.  The values may be given as fractional numbers;
-however, fractional basic units are always rounded to integers.
-
-   Some of the measurement units are completely independent of any of
-the current settings (e.g. type size) of `gtroff'.
-
-`i'
-     Inches.  An antiquated measurement unit still in use in certain
-     backwards countries with incredibly low-cost computer equipment.
-     One inch is equal to 2.54cm.
-
-`c'
-     Centimeters.  One centimeter is equal to 0.3937in.
-
-`p'
-     Points.  This is a typesetter's measurement used for measure type
-     size.  It is 72 points to an inch.
-
-`P'
-     Pica.  Another typesetting measurement.  6 Picas to an inch (and
-     12 points to a pica).
-
-`s'
-`z'
-     *Note Fractional Type Sizes::, for a discussion of these units.
-
-`f'
-     Fractions. Value is 65536.  *Note Colors::, for usage.
-
-   The other measurements understood by `gtroff' depend on settings
-currently in effect in `gtroff'.  These are very useful for specifying
-measurements which should look proper with any size of text.
-
-`m'
-     Ems.  This unit is equal to the current font size in points.  So
-     called because it is _approximately_ the width of the letter `m'
-     in the current font.
-
-`n'
-     Ens.  In `groff', this is half of an em.
-
-`v'
-     Vertical space.  This is equivalent to the current line spacing.
-     *Note Sizes::, for more information about this.
-
-`M'
-     100ths of an em.

-
-5.2.1 Default Units
--------------------
-
-Many requests take a default unit.  While this can be helpful at times,
-it can cause strange errors in some expressions.  For example, the line
-length request expects em units.  Here are several attempts to get a
-line length of 3.5 inches and their results:
-
-
-     3.5i      =>   3.5i
-     7/2       =>   0i
-     7/2i      =>   0i
-     (7 / 2)u  =>   0i
-     7i/2      =>   0.1i
-     7i/2u     =>   3.5i
-
-Everything is converted to basic units first.  In the above example it
-is assumed that 1i equals 240u, and 1m equals 10p (thus 1m equals 33u).
-The value 7i/2 is first handled as 7i/2m, then converted to 1680u/66u
-which is 25u, and this is approximately 0.1i.  As can be seen, a
-scaling indicator after a closing parenthesis is simply ignored.
-
-   Thus, the safest way to specify measurements is to always attach a
-scaling indicator.  If you want to multiply or divide by a certain
-scalar value, use `u' as the unit for that value.
-

-
-5.3 Expressions
-===============
-
-`gtroff' has most arithmetic operators common to other languages:
-
-   * Arithmetic: `+' (addition), `-' (subtraction), `/' (division), `*'
-     (multiplication), `%' (modulo).
-
-     `gtroff' only provides integer arithmetic.  The internal type used
-     for computing results is `int', which is usually a 32bit signed
-     integer.
-
-   * Comparison: `<' (less than), `>' (greater than), `<=' (less than
-     or equal), `>=' (greater than or equal), `=' (equal), `==' (the
-     same as `=').
-
-   * Logical: `&' (logical and), `:' (logical or).
-
-   * Unary operators: `-' (negating, i.e. changing the sign), `+' (just
-     for completeness; does nothing in expressions), `!' (logical not;
-     this works only within `if' and `while' requests).  See below for
-     the use of unary operators in motion requests.
-
-   * Extrema: `>?' (maximum), `<?' (minimum).
-
-     Example:
-
-
-          .nr x 5
-          .nr y 3
-          .nr z (\n[x] >? \n[y])
-
-     The register `z' now contains 5.
-
-   * Scaling: `(C;E)'.  Evaluate E using C as the default scaling
-     indicator.  If C is missing, ignore scaling indicators in the
-     evaluation of E.
-
-   Parentheses may be used as in any other language.  However, in
-`gtroff' they are necessary to ensure order of evaluation.  `gtroff'
-has no operator precedence; expressions are evaluated left to right.
-This means that `gtroff' evaluates `3+5*4' as if it were parenthesized
-like `(3+5)*4', not as `3+(5*4)', as might be expected.
-
-   For many requests which cause a motion on the page, the unary
-operators `+' and `-' work differently if leading an expression.  They
-then indicate a motion relative to the current position (down or up,
-respectively).
-
-   Similarly, a leading `|' operator indicates an absolute position.

-5.4 Identifiers
-===============
-
-Like any other language, `gtroff' has rules for properly formed
-"identifiers".  In `gtroff', an identifier can be made up of almost any
-printable character, with the exception of the following characters:
-
-   * Whitespace characters (spaces, tabs, and newlines).
-
-   * Backspace (ASCII `0x08' or EBCDIC `0x16') and character code
-     `0x01'.
-
-   * The following input characters are invalid and are ignored if
-     `groff' runs on a machine based on ASCII, causing a warning
-     message of type `input' (see *Note Debugging::, for more details):
-     `0x00', `0x0B', `0x0D'-`0x1F', `0x80'-`0x9F'.
-
-     And here are the invalid input characters if `groff' runs on an
-     EBCDIC host: `0x00', `0x08', `0x09', `0x0B', `0x0D'-`0x14',
-     `0x17'-`0x1F', `0x30'-`0x3F'.
-
-     Currently, some of these reserved codepoints are used internally,
-     thus making it non-trivial to extend `gtroff' to cover Unicode or
-     other character sets and encodings which use characters of these
-     ranges.
-
-     Note that invalid characters are removed before parsing; an
-     identifier `foo', followed by an invalid character, followed by
-     `bar' is treated as `foobar'.
-
-   For example, any of the following is valid.
-
-
-     br
-     PP
-     (l
-     end-list
-     @_
-
-Note that identifiers longer than two characters with a closing bracket
-(`]') in its name can't be accessed with escape sequences which expect
-an identifier as a parameter.  For example, `\[foo]]' accesses the
-glyph `foo', followed by `]', whereas `\C'foo]'' really asks for glyph
-`foo]'.
-
-   To avoid problems with the `refer' preprocessor, macro names should
-not start with `[' or `]'.  Due to backwards compatibility, everything
-after `.[' and `.]' is handled as a special argument to `refer'.  For
-example, `.[foo' makes `refer' to start a reference, using `foo' as a
-parameter.
-
- -- Escape: \A'ident'
-     Test whether an identifier IDENT is valid in `gtroff'.  It expands
-     to the character 1 or 0 according to whether its argument (usually
-     delimited by quotes) is or is not acceptable as the name of a
-     string, macro, diversion, number register, environment, or font.
-     It returns 0 if no argument is given.  This is useful for looking
-     up user input in some sort of associative table.
-
-
-          \A'end-list'
-              => 1
-
-
-   *Note Escapes::, for details on parameter delimiting characters.
-
-   Identifiers in `gtroff' can be any length, but, in some contexts,
-`gtroff' needs to be told where identifiers end and text begins (and in
-different ways depending on their length):
-
-   * Single character.
-
-   * Two characters.  Must be prefixed with `(' in some situations.
-
-   * Arbitrary length (`gtroff' only).  Must be bracketed with `['
-     and `]' in some situations.  Any length identifier can be put in
-     brackets.
-
-   Unlike many other programming languages, undefined identifiers are
-silently ignored or expanded to nothing.  When `gtroff' finds an
-undefined identifier, it emits a warning, doing the following:
-
-   * If the identifier is a string, macro, or diversion, `gtroff'
-     defines it as empty.
-
-   * If the identifier is a number register, `gtroff' defines it with a
-     value of 0.
-
-   *Note Warnings::., *Note Interpolating Registers::, and *Note
-Strings::.
-
-   Note that macros, strings, and diversions share the same name space.
-
-
-     .de xxx
-     .  nop foo
-     ..
-     .
-     .di xxx
-     bar
-     .br
-     .di
-     .
-     .xxx
-         => bar
-
-As can be seen in the previous example, `gtroff' reuses the identifier
-`xxx', changing it from a macro to a diversion.  No warning is emitted!
-The contents of the first macro definition is lost.

-5.5 Embedded Commands
-=====================
-
-Most documents need more functionality beyond filling, adjusting and
-implicit line breaking.  In order to gain further functionality,
-`gtroff' allows commands to be embedded into the text, in two ways.
-
-   The first is a "request" which takes up an entire line, and does
-some large-scale operation (e.g. break lines, start new pages).
-
-   The other is an "escape" which can be usually embedded anywhere in
-the text; most requests can accept it even as an argument.  Escapes
-generally do more minor operations like sub- and superscripts, print a
-symbol, etc.

-
-5.5.1 Requests
---------------
-
-A request line begins with a control character, which is either a single
-quote (`'', the "no-break control character") or a period (`.', the
-normal "control character").  These can be changed; see *Note Character
-Translations::, for details.  After this there may be optional tabs or
-spaces followed by an identifier which is the name of the request.
-This may be followed by any number of space-separated arguments (_no_
-tabs here).
-
-   Since a control character followed by whitespace only is ignored, it
-is common practice to use this feature for structuring the source code
-of documents or macro packages.
-
-
-     .de foo
-     .  tm This is foo.
-     ..
-     .
-     .
-     .de bar
-     .  tm This is bar.
-     ..
-
-   Another possibility is to use the blank line macro request `blm' by
-assigning an empty macro to it.
-
-
-     .de do-nothing
-     ..
-     .blm do-nothing  \" activate blank line macro
-
-     .de foo
-     .  tm This is foo.
-     ..
-
-
-     .de bar
-     .  tm This is bar.
-     ..
-
-     .blm             \" deactivate blank line macro
-
-   *Note Blank Line Traps::.
-
-   To begin a line with a control character without it being
-interpreted, precede it with `\&'.  This represents a zero width space,
-which means it does not affect the output.
-
-   In most cases the period is used as a control character.  Several
-requests cause a break implicitly; using the single quote control
-character prevents this.

-5.5.1.1 Request and Macro Arguments
-...................................
-
-Arguments to requests and macros are processed much like the shell: The
-line is split into arguments according to spaces.(1) (*note Request and
-Macro Arguments-Footnote-1::)
-
-   An argument to a macro which is intended to contain spaces can
-either be enclosed in double quotes, or have the spaces "escaped" with
-backslashes.  This is _not_ true for requests.
-
-   Here are a few examples for a hypothetical macro `uh':
-
-
-     .uh The Mouse Problem
-     .uh "The Mouse Problem"
-     .uh The\ Mouse\ Problem
-
-The first line is the `uh' macro being called with 3 arguments, `The',
-`Mouse', and `Problem'.  The latter two have the same effect of calling
-the `uh' macro with one argument, `The Mouse Problem'.(2) (*note
-Request and Macro Arguments-Footnote-2::)
-
-   A double quote which isn't preceded by a space doesn't start a macro
-argument.  If not closing a string, it is printed literally.
-
-   For example,
-
-
-     .xxx a" "b c" "de"fg"
-
-has the arguments `a"', `b c', `de', and `fg"'.  Don't rely on this
-obscure behaviour!
-
-   There are two possibilities to get a double quote reliably.
-
-   * Enclose the whole argument with double quotes and use two
-     consecutive double quotes to represent a single one.  This
-     traditional solution has the disadvantage that double quotes don't
-     survive argument expansion again if called in compatibility mode
-     (using the `-C' option of `groff'):
-
-
-          .de xx
-          .  tm xx: `\\$1' `\\$2' `\\$3'
-          .
-          .  yy "\\$1" "\\$2" "\\$3"
-          ..
-          .de yy
-          .  tm yy: `\\$1' `\\$2' `\\$3'
-          ..
-          .xx A "test with ""quotes""" .
-              => xx: `A' `test with "quotes"' `.'
-              => yy: `A' `test with ' `quotes""'
-
-     If not in compatibility mode, you get the expected result
-
-
-          xx: `A' `test with "quotes"' `.'
-          yy: `A' `test with "quotes"' `.'
-
-     since `gtroff' preserves the input level.
-
-   * Use the double quote glyph `\(dq'.  This works with and without
-     compatibility mode enabled since `gtroff' doesn't convert `\(dq'
-     back to a double quote input character.
-
-     Not that this method won't work with UNIX `troff' in general since
-     the glyph `dq' isn't defined normally.
-
-   Double quotes in the `ds' request are handled differently.  *Note
-Strings::, for more details.
-
-
-File: groff,  Node: Request and Macro Arguments-Footnotes,  Up: Request and Macro Arguments
-
-   (1) Plan 9's `troff' implementation also allows tabs for argument
-separation - `gtroff' intentionally doesn't support this.
-
-   (2) The last solution, i.e., using escaped spaces, is "classical" in
-the sense that it can be found in most `troff' documents.
-Nevertheless, it is not optimal in all situations, since `\ ' inserts a
-fixed-width, non-breaking space character which can't stretch.
-`gtroff' provides a different command `\~' to insert a stretchable,
-non-breaking space.

-
-5.5.2 Macros
-------------
-
-`gtroff' has a "macro" facility for defining a series of lines which
-can be invoked by name.  They are called in the same manner as requests
-- arguments also may be passed basically in the same manner.
-
-   *Note Writing Macros::, and *Note Request and Macro Arguments::.
-
-
-File: groff,  Node: Escapes,  Prev: Macros,  Up: Embedded Commands
-
-5.5.3 Escapes
--------------
-
-Escapes may occur anywhere in the input to `gtroff'.  They usually
-begin with a backslash and are followed by a single character which
-indicates the function to be performed.  The escape character can be
-changed; see *Note Character Translations::.
-
-   Escape sequences which require an identifier as a parameter accept
-three possible syntax forms.
-
-   * The next single character is the identifier.
-
-   * If this single character is an opening parenthesis, take the
-     following two characters as the identifier.  Note that there is no
-     closing parenthesis after the identifier.
-
-   * If this single character is an opening bracket, take all characters
-     until a closing bracket as the identifier.
-
-Examples:
-
-
-     \fB
-     \n(XX
-     \*[TeX]
-
-   Other escapes may require several arguments and/or some special
-format.  In such cases the argument is traditionally enclosed in single
-quotes (and quotes are always used in this manual for the definitions
-of escape sequences).  The enclosed text is then processed according to
-what that escape expects.  Example:
-
-
-     \l'1.5i\(bu'
-
-   Note that the quote character can be replaced with any other
-character which does not occur in the argument (even a newline or a
-space character) in the following escapes: `\o', `\b', and `\X'.  This
-makes e.g.
-
-
-     A caf
-     \o
-     e\'
-
-
-     in Paris
-       => A café in Paris
-
-possible, but it is better not to use this feature to avoid confusion.
-
-   The following escapes sequences (which are handled similarly to
-characters since they don't take a parameter) are also allowed as
-delimiters: `\%', `\ ', `\|', `\^', `\{', `\}', `\'', `\`', `\-', `\_',
-`\!', `\?', `\@', `\)', `\/', `\,', `\&', `\:', `\~', `\0', `\a', `\c',
-`\d', `\e', `\E', `\p', `\r', `\t', and `\u'.  Again, don't use these
-if possible.
-
-   No newline characters as delimiters are allowed in the following
-escapes: `\A', `\B', `\Z', `\C', and `\w'.
-
-   Finally, the escapes `\D', `\h', `\H', `\l', `\L', `\N', `\R', `\s',
-`\S', `\v', and `\x' can't use the following characters as delimiters:
-
-   * The digits `0'-`9'.
-
-   * The (single-character) operators `+-/*%<>=&:().'.
-
-   * The space, tab, and newline characters.
-
-   * All escape sequences except `\%', `\:', `\{', `\}', `\'', `\`',
-     `\-', `\_', `\!', `\@', `\/', `\c', `\e', and `\p'.
-
-   To have a backslash (actually, the current escape character) appear
-in the output several escapes are defined: `\\', `\e' or `\E'.  These
-are very similar, and only differ with respect to being used in macros
-or diversions.  *Note Character Translations::, for an exact
-description of those escapes.

-
-5.5.3.1 Comments
-................
-
-Probably one of the most(1) (*note Comments-Footnote-1::) common forms
-of escapes is the comment.
-
- -- Escape: \"
-     Start a comment.  Everything to the end of the input line is
-     ignored.
-
-     This may sound simple, but it can be tricky to keep the comments
-     from interfering with the appearance of the final output.
-
-     If the escape is to the right of some text or a request, that
-     portion of the line is ignored, but the space leading up to it is
-     noticed by `gtroff'.  This only affects the `ds' and `as' request
-     and its variants.
-
-     One possibly irritating idiosyncracy is that tabs must not be used
-     to line up comments.  Tabs are not treated as whitespace between
-     the request and macro arguments.
-
-     A comment on a line by itself is treated as a blank line, because
-     after eliminating the comment, that is all that remains:
-
-
-          Test
-          \" comment
-          Test
-
-     produces
-
-
-          Test
-
-          Test
-
-     To avoid this, it is common to start the line with `.\"' which
-     causes the line to be treated as an undefined request and thus
-     ignored completely.
-
-     Another commenting scheme seen sometimes is three consecutive
-     single quotes (`'''') at the beginning of a line.  This works, but
-     `gtroff' gives a warning about an undefined macro (namely `'''),
-     which is harmless, but irritating.
-
- -- Escape: \#
-     To avoid all this, `gtroff' has a new comment mechanism using the
-     `\#' escape.  This escape works the same as `\"' except that the
-     newline is also ignored:
-
-
-          Test
-          \# comment
-          Test
-
-     produces
-
-
-          Test Test
-
-     as expected.
-
- -- Request: .ig [end]
-     Ignore all input until `gtroff' encounters the macro named `.'END
-     on a line by itself (or `..' if END is not specified).  This is
-     useful for commenting out large blocks of text:
-
-
-          text text text...
-          .ig
-          This is part of a large block
-          of text that has been
-          temporarily(?) commented out.
-
-          We can restore it simply by removing
-          the .ig request and the ".." at the
-          end of the block.
-          ..
-          More text text text...
-
-     produces
-
-
-          text text text...  More text text text...
-
-     Note that the commented-out block of text does not cause a break.
-
-     The input is read in copy-mode; auto-incremented registers _are_
-     affected (*note Auto-increment::).

-5.6.1 Setting Registers
------------------------
-
-Define or set registers using the `nr' request or the `\R' escape.
-
- -- Request: .nr ident value
- -- Escape: \R'ident value'
-     Set number register IDENT to VALUE.  If IDENT doesn't exist,
-     `gtroff' creates it.
-
-     The argument to `\R' usually has to be enclosed in quotes.  *Note
-     Escapes::, for details on parameter delimiting characters.
-
-     The `\R' escape doesn't produce an input token in `gtroff'; with
-     other words, it vanishes completely after `gtroff' has processed
-     it.
-
-   For example, the following two lines are equivalent:
-
-
-     .nr a (((17 + (3 * 4))) % 4)
-     \R'a (((17 + (3 * 4))) % 4)'
-         => 1
-
-   Both `nr' and `\R' have two additional special forms to increment or
-decrement a register.
-
- -- Request: .nr ident +value
- -- Request: .nr ident -value
- -- Escape: \R'ident +value'
- -- Escape: \R'ident -value'
-     Increment (decrement) register IDENT by VALUE.
-
-
-          .nr a 1
-          .nr a +1
-          \na
-              => 2
-
-     To assign the negated value of a register to another register,
-     some care must be taken to get the desired result:
-
-
-          .nr a 7
-          .nr b 3
-          .nr a -\nb
-          \na
-              => 4
-          .nr a (-\nb)
-          \na
-              => -3
-
-     The surrounding parentheses prevent the interpretation of the
-     minus sign as a decrementing operator.  An alternative is to start
-     the assignment with a `0':
-
-
-          .nr a 7
-          .nr b -3
-          .nr a \nb
-          \na
-              => 4
-          .nr a 0\nb
-          \na
-              => -3
-
-
- -- Request: .rr ident
-     Remove number register IDENT.  If IDENT doesn't exist, the request
-     is ignored.
-
- -- Request: .rnn ident1 ident2
-     Rename number register IDENT1 to IDENT2.  If either IDENT1 or
-     IDENT2 doesn't exist, the request is ignored.
-
- -- Request: .aln ident1 ident2
-     Create an alias IDENT1 for a number register IDENT2.  The new name
-     and the old name are exactly equivalent.  If IDENT1 is undefined,
-     a warning of type `reg' is generated, and the request is ignored.
-     *Note Debugging::, for information about warnings.

-5.6.2 Interpolating Registers
------------------------------
-
-Numeric registers can be accessed via the `\n' escape.
-
- -- Escape: \ni
- -- Escape: \n(id
- -- Escape: \n[ident]
-     Interpolate number register with name IDENT (one-character name I,
-     two-character name ID).  This means that the value of the register
-     is expanded in-place while `gtroff' is parsing the input line.
-     Nested assignments (also called indirect assignments) are possible.
-
-
-          .nr a 5
-          .nr as \na+\na
-          \n(as
-              => 10

-5.6.3 Auto-increment
---------------------
-
-Number registers can also be auto-incremented and auto-decremented.
-The increment or decrement value can be specified with a third argument
-to the `nr' request or `\R' escape.
-
- -- Request: .nr ident value incr
-     Set number register IDENT to VALUE; the increment for
-     auto-incrementing is set to INCR.  Note that the `\R' escape
-     doesn't support this notation.
-
-   To activate auto-incrementing, the escape `\n' has a special syntax
-form.
-
- -- Escape: \n+i
- -- Escape: \n-i
- -- Escape: \n(+id
- -- Escape: \n(-id
- -- Escape: \n+(id
- -- Escape: \n-(id
- -- Escape: \n[+ident]
- -- Escape: \n[-ident]

-     Before interpolating, increment or decrement IDENT (one-character
-     name I, two-character name ID) by the auto-increment value as
-     specified with the `nr' request (or the `\R' escape).  If no
-     auto-increment value has been specified, these syntax forms are
-     identical to `\n'.

-     \n-(xx, \n-(xx, \n-(xx, \n-(xx, \n-(xx
-     .br
-     \n+[foo], \n+[foo], \n+[foo], \n+[foo], \n+[foo]

-     -5, -10, -15, -20, -25
-     -2, -4, -6, -8, -10

-5.6.4 Assigning Formats
------------------------
-
-When a register is used in the text of an input file (as opposed to
-part of an expression), it is textually replaced (or interpolated) with
-a representation of that number.  This output format can be changed to
-a variety of formats (numbers, Roman numerals, etc.).  This is done
-using the `af' request.
-
- -- Request: .af ident format
-     Change the output format of a number register.  The first argument
-     IDENT is the name of the number register to be changed, and the
-     second argument FORMAT is the output format.  The following output
-     formats are available:
-
-    `1'
-          Decimal arabic numbers.  This is the default format: 0, 1, 2,
-          3, ....
-
-    `0...0'
-          Decimal numbers with as many digits as specified.  So, `00'
-          would result in printing numbers as 01, 02, 03, ....
-
-          In fact, any digit instead of zero will do; `gtroff' only
-          counts how many digits are specified.  As a consequence,
-          `af''s default format `1' could be specified as `0' also (and
-          exactly this is returned by the `\g' escape, see below).
-
-    `I'
-          Upper-case Roman numerals: 0, I, II, III, IV, ....
-
-    `i'
-          Lower-case Roman numerals: 0, i, ii, iii, iv, ....
-
-    `A'
-          Upper-case letters: 0, A, B, C, ..., Z, AA, AB, ....
-
-    `a'
-          Lower-case letters: 0, a, b, c, ..., z, aa, ab, ....
-
-     Omitting the number register format causes a warning of type
-     `missing'.  *Note Debugging::, for more details.  Specifying a
-     nonexistent format causes an error.
-
-     The following example produces `10, X, j, 010':
-
-
-          .nr a 10
-          .af a 1           \" the default format
-          \na,
-          .af a I
-          \na,
-          .af a a
-          \na,
-          .af a 001
-          \na
-
-     The largest number representable for the `i' and `I' formats is
-     39999 (or -39999); UNIX `troff' uses `z' and `w' to represent
-     10000 and 5000 in Roman numerals, and so does `gtroff'.
-     Currently, the correct glyphs of Roman numeral five thousand and
-     Roman numeral ten thousand (Unicode code points `U+2182' and
-     `U+2181', respectively) are not available.
-
-     If IDENT doesn't exist, it is created.
-
-     Changing the output format of a read-only register causes an
-     error.  It is necessary to first copy the register's value to a
-     writeable register, then apply the `af' request to this other
-     register.
-
- -- Escape: \gi
- -- Escape: \g(id
- -- Escape: \g[ident]
-     Return the current format of the specified register IDENT
-     (one-character name I, two-character name ID).  For example, `\ga'
-     after the previous example would produce the string `000'.  If the
-     register hasn't been defined yet, nothing is returned.

-5.6.5 Built-in Registers
-------------------------
-
-The following lists some built-in registers which are not described
-elsewhere in this manual.  Any register which begins with a `.' is
-read-only.  A complete listing of all built-in registers can be found in
-*Note Register Index::.
-
-`\n[.F]'
-     This string-valued register returns the current input file name.
-
-`\n[.H]'
-     Horizontal resolution in basic units.
-
-`\n[.U]'
-     If `gtroff' is called with the `-U' command line option, the
-     number register `.U' is set to 1, and zero otherwise.  *Note Groff
-     Options::.
-
-`\n[.V]'
-     Vertical resolution in basic units.
-
-`\n[seconds]'
-     The number of seconds after the minute, normally in the range 0
-     to 59, but can be up to 61 to allow for leap seconds.  Initialized
-     at start-up of `gtroff'.
-
-`\n[minutes]'
-     The number of minutes after the hour, in the range 0 to 59.
-     Initialized at start-up of `gtroff'.
-
-`\n[hours]'
-     The number of hours past midnight, in the range 0 to 23.
-     Initialized at start-up of `gtroff'.
-
-`\n[dw]'
-     Day of the week (1-7).
-
-`\n[dy]'
-     Day of the month (1-31).
-
-`\n[mo]'
-     Current month (1-12).
-
-`\n[year]'
-     The current year.
-
-`\n[yr]'
-     The current year minus 1900.  Unfortunately, the documentation of
-     UNIX Version 7's `troff' had a year 2000 bug: It incorrectly
-     claimed that `yr' contains the last two digits of the year.  That
-     claim has never been true of either AT&T `troff' or GNU `troff'.
-     Old `troff' input that looks like this:
-
-
-          '\" The following line stopped working after 1999
-          This document was formatted in 19\n(yr.
-
-     can be corrected as follows:
-
-
-          This document was formatted in \n[year].
-
-     or, to be portable to older `troff' versions, as follows:
-
-
-          .nr y4 1900+\n(yr
-          This document was formatted in \n(y4.
-
-`\n[.c]'
-`\n[c.]'
-     The current _input_ line number.  Register `.c' is read-only,
-     whereas `c.' (a `gtroff' extension) is writable also, affecting
-     both `.c' and `c.'.
-
-`\n[ln]'
-     The current _output_ line number after a call to the `nm' request
-     to activate line numbering.
-
-     *Note Miscellaneous::, for more information about line numbering.
-
-`\n[.x]'
-     The major version number.  For example, if the version number is
-     1.03 then `.x' contains `1'.
-
-`\n[.y]'
-     The minor version number.  For example, if the version number is
-     1.03 then `.y' contains `03'.
-
-`\n[.Y]'
-     The revision number of `groff'.
-
-`\n[$$]'
-     The process ID of `gtroff'.
-
-`\n[.g]'
-     Always 1.  Macros should use this to determine whether they are
-     running under GNU `troff'.
-
-`\n[.A]'
-     If the command line option `-a' is used to produce an ASCII
-     approximation of the output, this is set to 1, zero otherwise.
-     *Note Groff Options::.
-
-`\n[.P]'
-     This register is set to 1 (and to 0 otherwise) if the current page
-     is actually being printed, i.e., if the `-o' option is being used
-     to only print selected pages.  *Note Groff Options::, for more
-     information.
-
-`\n[.T]'
-     If `gtroff' is called with the `-T' command line option, the
-     number register `.T' is set to 1, and zero otherwise.  *Note Groff
-     Options::.
-
-`\*[.T]'
-     A single read-write string register which contains the current
-     output device (for example, `latin1' or `ps').  This is the only
-     string register defined by `gtroff'.

-5.7 Manipulating Filling and Adjusting
-======================================
-
-Various ways of causing "breaks" were given in *Note Implicit Line
-Breaks::.  The `br' request likewise causes a break.  Several other
-requests also cause breaks, but implicitly.  These are `bp', `ce',
-`cf', `fi', `fl', `in', `nf', `rj', `sp', `ti', and `trf'.
-
- -- Request: .br
-     Break the current line, i.e., the input collected so far is emitted
-     without adjustment.
-
-     If the no-break control character is used, `gtroff' suppresses the
-     break:
-
-
-          a
-          'br
-          b
-              => a b
-
-
-   Initially, `gtroff' fills and adjusts text to both margins.  Filling
-can be disabled via the `nf' request and re-enabled with the `fi'
-request.
-
- -- Request: .fi
- -- Register: \n[.u]
-     Activate fill mode (which is the default).  This request implicitly
-     enables adjusting; it also inserts a break in the text currently
-     being filled.  The read-only number register `.u' is set to 1.
-
-     The fill mode status is associated with the current environment
-     (*note Environments::).
-
-     See *Note Line Control::, for interaction with the `\c' escape.
-
- -- Request: .nf
-     Activate no-fill mode.  Input lines are output as-is, retaining
-     line breaks and ignoring the current line length.  This command
-     implicitly disables adjusting; it also causes a break.  The number
-     register `.u' is set to 0.
-
-     The fill mode status is associated with the current environment
-     (*note Environments::).
-
-     See *Note Line Control::, for interaction with the `\c' escape.
-
- -- Request: .ad [mode]
- -- Register: \n[.j]
-     Set adjusting mode.
-
-     Activation and deactivation of adjusting is done implicitly with
-     calls to the `fi' or `nf' requests.
-
-     MODE can have one of the following values:
-
-    `l'
-          Adjust text to the left margin.  This produces what is
-          traditionally called ragged-right text.
-
-    `r'
-          Adjust text to the right margin, producing ragged-left text.
-
-    `c'
-          Center filled text.  This is different to the `ce' request
-          which only centers text without filling.
-
-    `b'
-    `n'
-          Justify to both margins.  This is the default used by
-          `gtroff'.
-
-     Finally, MODE can be the numeric argument returned by the `.j'
-     register.
-
-     With no argument, `gtroff' adjusts lines in the same way it did
-     before adjusting was deactivated (with a call to `na', for
-     example).
-
-
-          text
-          .ad r
-          .nr ad \n[.j]
-          text
-          .ad c
-          text
-          .na
-          text
-          .ad         \" back to centering
-          text
-          .ad \n[ad]  \" back to right justifying
-
-     The current adjustment mode is available in the read-only number
-     register `.j'; it can be stored and subsequently used to set
-     adjustment.
-
-     The adjustment mode status is associated with the current
-     environment (*note Environments::).
-
- -- Request: .na
-     Disable adjusting.  This request won't change the current
-     adjustment mode: A subsequent call to `ad' uses the previous
-     adjustment setting.
-
-     The adjustment mode status is associated with the current
-     environment (*note Environments::).
-
- -- Request: .brp
- -- Escape: \p
-     Adjust the current line and cause a break.
-
-     In most cases this produces very ugly results since `gtroff'
-     doesn't have a sophisticated paragraph building algorithm (as TeX
-     have, for example); instead, `gtroff' fills and adjusts a paragraph
-     line by line:
-
-
-            This is an uninteresting sentence.
-            This is an uninteresting sentence.\p
-            This is an uninteresting sentence.
-
-     is formatted as
-
-
-            This is  an uninteresting  sentence.   This  is an
-            uninteresting                            sentence.
-            This is an uninteresting sentence.
-
-
- -- Request: .ss word_space_size [sentence_space_size]
- -- Register: \n[.ss]
- -- Register: \n[.sss]
-     Change the size of a space between words.  It takes its units as
-     one twelfth of the space width parameter for the current font.
-     Initially both the WORD_SPACE_SIZE and SENTENCE_SPACE_SIZE are 12.
-     In fill mode, the values specify the minimum distance.
-
-     If two arguments are given to the `ss' request, the second
-     argument sets the sentence space size.  If the second argument is
-     not given, sentence space size is set to WORD_SPACE_SIZE.  The
-     sentence space size is used in two circumstances: If the end of a
-     sentence occurs at the end of a line in fill mode, then both an
-     inter-word space and a sentence space are added; if two spaces
-     follow the end of a sentence in the middle of a line, then the
-     second space is a sentence space.  If a second argument is never
-     given to the `ss' request, the behaviour of UNIX `troff' is the
-     same as that exhibited by GNU `troff'.  In GNU `troff', as in UNIX
-     `troff', a sentence should always be followed by either a newline
-     or two spaces.
-
-     The read-only number registers `.ss' and `.sss' hold the values of
-     the parameters set by the first and second arguments of the `ss'
-     request.
-
-     The word space and sentence space values are associated with the
-     current environment (*note Environments::).
-
-     Contrary to AT&T `troff', this request is _not_ ignored if a TTY
-     output device is used; the given values are then rounded down to a
-     multiple of 12 (*note Implementation Differences::).
-
-     The request is ignored if there is no parameter.
-
-     Another useful application of the `ss' request is to insert
-     discardable horizontal space, i.e., space which is discarded at a
-     line break.  For example, paragraph-style footnotes could be
-     separated this way:
-
-
-          .ll 4.5i
-          1.\ This is the first footnote.\c
-          .ss 48
-          .nop
-          .ss 12
-          2.\ This is the second footnote.
-
-     The result:
-
-
-          1. This is the first footnote.        2. This
-          is the second footnote.
-
-     Note that the `\h' escape produces unbreakable space.
-
- -- Request: .ce [nnn]
- -- Register: \n[.ce]
-     Center text.  While the `.ad c' request also centers text, it
-     fills the text as well.  `ce' does not fill the text it affects.
-     This request causes a break.  The number of lines still to be
-     centered is associated with the current environment (*note
-     Environments::).
-
-     The following example demonstrates the differences.  Here the
-     input:
-
-
-          .ll 4i
-          .ce 1000
-          This is a small text fragment which shows the differences
-          between the `.ce' and the `.ad c' request.
-          .ce 0
-
-          .ad c
-          This is a small text fragment which shows the differences
-          between the `.ce' and the `.ad c' request.
-
-     And here the result:
-
-
-            This is a small text fragment which
-                   shows the differences
-          between the `.ce' and the `.ad c' request.
-
-            This is a small text fragment which
-          shows the differences between the `.ce'
-                  and the `.ad c' request.
-
-     With no arguments, `ce' centers the next line of text.  NNN
-     specifies the number of lines to be centered.  If the argument is
-     zero or negative, centering is disabled.
-
-     The basic length for centering text is the line length (as set
-     with the `ll' request) minus the indentation (as set with the `in'
-     request).  Temporary indentation is ignored.
-
-     As can be seen in the previous example, it is a common idiom to
-     turn on centering for a large number of lines, and to turn off
-     centering after text to be centered.  This is useful for any
-     request which takes a number of lines as an argument.
-
-     The `.ce' read-only number register contains the number of lines
-     remaining to be centered, as set by the `ce' request.
-
- -- Request: .rj [nnn]
- -- Register: \n[.rj]
-     Justify unfilled text to the right margin.  Arguments are
-     identical to the `ce' request.  The `.rj' read-only number
-     register is the number of lines to be right-justified as set by
-     the `rj' request.  This request causes a break.  The number of
-     lines still to be right-justified is associated with the current
-     environment (*note Environments::).

-5.8 Manipulating Hyphenation
-============================
-
-Here a description of requests which influence hyphenation.
-
- -- Request: .hy [mode]
- -- Register: \n[.hy]
-     Enable hyphenation.  The request has an optional numeric argument,
-     MODE, to restrict hyphenation if necessary:
-
-    `1'
-          The default argument if MODE is omitted.  Hyphenate without
-          restrictions.  This is also the start-up value of `gtroff'.
-
-    `2'
-          Do not hyphenate the last word on a page or column.
-
-    `4'
-          Do not hyphenate the last two characters of a word.
-
-    `8'
-          Do not hyphenate the first two characters of a word.
-
-     Values in the previous table are additive.  For example, the
-     value 12 causes `gtroff' to neither hyphenate the last two nor the
-     first two characters of a word.
-
-     The current hyphenation restrictions can be found in the read-only
-     number register `.hy'.
-
-     The hyphenation mode is associated with the current environment
-     (*note Environments::).
-
- -- Request: .nh
-     Disable hyphenation (i.e., set the hyphenation mode to zero).  Note
-     that the hyphenation mode of the last call to `hy' is not
-     remembered.
-
-     The hyphenation mode is associated with the current environment
-     (*note Environments::).
-
- -- Request: .hlm [nnn]
- -- Register: \n[.hlm]
- -- Register: \n[.hlc]
-     Set the maximum number of consecutive hyphenated lines to NNN.  If
-     this number is negative, there is no maximum.  The default value
-     is -1 if NNN is omitted.  This value is associated with the
-     current environment (*note Environments::).  Only lines output
-     from a given environment count towards the maximum associated with
-     that environment.  Hyphens resulting from `\%' are counted;
-     explicit hyphens are not.
-
-     The current setting of `hlm' is available in the `.hlm' read-only
-     number register.  Also the number of immediately preceding
-     consecutive hyphenated lines are available in the read-only number
-     register `.hlc'.
-
- -- Request: .hw word1 word2 ...
-     Define how WORD1, WORD2, etc. are to be hyphenated.  The words
-     must be given with hyphens at the hyphenation points.  For example:
-
-
-          .hw in-sa-lub-rious
-
-     Besides the space character, any character whose hyphenation code
-     value is zero can be used to separate the arguments of `hw' (see
-     the documentation for the `hcode' request below for more
-     information).  In addition, this request can be used more than
-     once.
-
-     Hyphenation exceptions specified with the `hw' request are
-     associated with the current hyphenation language; it causes an
-     error if there is no current hyphenation language.
-
-     This request is ignored if there is no parameter.
-
-     In old versions of `troff' there was a limited amount of space to
-     store such information; fortunately, with `gtroff', this is no
-     longer a restriction.
-
- -- Escape: \%
- -- Escape: \:
-     To tell `gtroff' how to hyphenate words on the fly, use the `\%'
-     escape, also known as the "hyphenation character".  Preceding a
-     word with this character prevents it from being hyphenated;
-     putting it inside a word indicates to `gtroff' that the word may
-     be hyphenated at that point.  Note that this mechanism only
-     affects that one occurrence of the word; to change the hyphenation
-     of a word for the entire document, use the `hw' request.
-
-     The `\:' escape inserts a zero-width break point (that is, the
-     word breaks but without adding a hyphen).
-
-
-          ... check the /var/log/\:httpd/\:access_log file ...
-
-     Note that `\X' and `\Y' start a word, that is, the `\%' escape in
-     (say) `\X'...'\%foobar' and `\Y'...'\%foobar' no longer prevents
-     hyphenation but inserts a hyphenation point at the beginning of
-     `foobar'; most likely this isn't what you want to do.
-
- -- Request: .hc [char]
-     Change the hyphenation character to CHAR.  This character then
-     works the same as the `\%' escape, and thus, no longer appears in
-     the output.  Without an argument, `hc' resets the hyphenation
-     character to be `\%' (the default) only.
-
-     The hyphenation character is associated with the current
-     environment (*note Environments::).
-
- -- Request: .hpf pattern_file
- -- Request: .hpfa pattern_file
- -- Request: .hpfcode a b [c d ...]
-     Read in a file of hyphenation patterns.  This file is searched for
-     in the same way as `NAME.tmac' (or `tmac.NAME') is searched for if
-     the `-mNAME' option is specified.
-
-     It should have the same format as (simple) TeX patterns files.
-     More specifically, the following scanning rules are implemented.
-
-        * A percent sign starts a comment (up to the end of the line)
-          even if preceded by a backslash.
-
-        * No support for `digraphs' like `\$'.
-
-        * `^^XX' (X is 0-9 or a-f) and `^^X' (character code of X in
-          the range 0-127) are recognized; other use of `^' causes an
-          error.
-
-        * No macro expansion.
-
-        * `hpf' checks for the expression `\patterns{...}' (possibly
-          with whitespace before and after the braces).  Everything
-          between the braces is taken as hyphenation patterns.
-          Consequently, `{' and `}' are not allowed in patterns.
-
-        * Similarly, `\hyphenation{...}' gives a list of hyphenation
-          exceptions.
-
-        * `\endinput' is recognized also.
-
-        * For backwards compatibility, if `\patterns' is missing, the
-          whole file is treated as a list of hyphenation patterns (only
-          recognizing the `%' character as the start of a comment).
-
-     If no `hpf' request is specified (either in the document or in a
-     macro package), `gtroff' won't hyphenate at all.
-
-     The `hpfa' request appends a file of patterns to the current list.
-
-     The `hpfcode' request defines mapping values for character codes in
-     hyphenation patterns.  `hpf' or `hpfa' then apply the mapping
-     (after reading the patterns) before replacing or appending them to
-     the current list of patterns.  Its arguments are pairs of
-     character codes - integers from 0 to 255.  The request maps
-     character code A to code B, code C to code D, and so on.  You can
-     use character codes which would be invalid otherwise.
-
-     The set of hyphenation patterns is associated with the current
-     language set by the `hla' request.  The `hpf' request is usually
-     invoked by the `troffrc' or `troffrc-end' file; by default,
-     `troffrc' loads hyphenation patterns and exceptions for American
-     English (in files `hyphen.us' and `hyphenex.us').
-
-     A second call to `hpf' (for the same language) will replace the
-     hyphenation patterns with the new ones.
-
-     Invoking `hpf' causes an error if there is no current hyphenation
-     language.
-
- -- Request: .hcode c1 code1 [c2 code2 ...]
-     Set the hyphenation code of character C1 to CODE1, that of C2 to
-     CODE2, etc.  A hyphenation code must be a single input character
-     (not a special character) other than a digit or a space.
-
-     To make hyphenation work, hyphenation codes must be set up.  At
-     start-up, groff only assigns hyphenation codes to the letters
-     `a'-`z' (mapped to themselves) and to the letters `A'-`Z' (mapped
-     to `a'-`z'); all other hyphenation codes are set to zero.
-     Normally, hyphenation patterns contain only lowercase letters
-     which should be applied regardless of case.  With other words, the
-     words `FOO' and `Foo' should be hyphenated exactly the same way as
-     the word `foo' is hyphenated, and this is what `hcode' is good
-     for.  Words which contain other letters won't be hyphenated
-     properly if the corresponding hyphenation patterns actually do
-     contain them.  For example, the following `hcode' requests are
-     necessary to assign hyphenation codes to the letters `ÄäÖöÜüß'
-     (this is needed for German):
-
-
-          .hcode ä ä  Ä ä
-          .hcode ö ö  Ö ö
-          .hcode ü ü  Ü ü
-          .hcode ß ß
-
-     Without those assignments, groff treats German words like
-     `Kindergärten' (the plural form of `kindergarten') as two
-     substrings `kinderg' and `rten' because the hyphenation code of
-     the umlaut a is zero by default.  There is a German hyphenation
-     pattern which covers `kinder', so groff finds the hyphenation
-     `kin-der'.  The other two hyphenation points (`kin-der-gär-ten')
-     are missed.
-
-     This request is ignored if it has no parameter.
-
- -- Request: .hym [length]
- -- Register: \n[.hym]
-     Set the (right) hyphenation margin to LENGTH.  If the current
-     adjustment mode is not `b' or `n', the line is not hyphenated if
-     it is shorter than LENGTH.  Without an argument, the hyphenation
-     margin is reset to its default value, which is 0.  The default
-     scaling indicator for this request is `m'.  The hyphenation margin
-     is associated with the current environment (*note Environments::).
-
-     A negative argument resets the hyphenation margin to zero, emitting
-     a warning of type `range'.
-
-     The current hyphenation margin is available in the `.hym' read-only
-     number register.
-
- -- Request: .hys [hyphenation_space]
- -- Register: \n[.hys]
-     Set the hyphenation space to HYPHENATION_SPACE.  If the current
-     adjustment mode is `b' or `n', don't hyphenate the line if it can
-     be justified by adding no more than HYPHENATION_SPACE extra space
-     to each word space.  Without argument, the hyphenation space is
-     set to its default value, which is 0.  The default scaling
-     indicator for this request is `m'.  The hyphenation space is
-     associated with the current environment (*note Environments::).
-
-     A negative argument resets the hyphenation space to zero, emitting
-     a warning of type `range'.
-
-     The current hyphenation space is available in the `.hys' read-only
-     number register.
-
- -- Request: .shc [glyph]
-     Set the "soft hyphen character" to GLYPH.(1) (*note Manipulating
-     Hyphenation-Footnote-1::)  If the argument is omitted, the soft
-     hyphen character is set to the default glyph `\(hy' (this is the
-     start-up value of `gtroff' also).  The soft hyphen character is
-     the glyph that is inserted when a word is hyphenated at a line
-     break.  If the soft hyphen character does not exist in the font of
-     the character immediately preceding a potential break point, then
-     the line is not broken at that point.  Neither definitions
-     (specified with the `char' request) nor translations (specified
-     with the `tr' request) are considered when finding the soft hyphen
-     character.
-
- -- Request: .hla language
- -- Register: \n[.hla]
-     Set the current hyphenation language to the string LANGUAGE.
-     Hyphenation exceptions specified with the `hw' request and
-     hyphenation patterns specified with the `hpf' and `hpfa' requests
-     are both associated with the current hyphenation language.  The
-     `hla' request is usually invoked by the `troffrc' or the
-     `troffrc-end' files; `troffrc' sets the default language to `us'.
-

-5.9 Manipulating Spacing
-========================
-
- -- Request: .sp [distance]
-     Space downwards DISTANCE.  With no argument it advances 1 line.  A
-     negative argument causes `gtroff' to move up the page the
-     specified distance.  If the argument is preceded by a `|' then
-     `gtroff' moves that distance from the top of the page.  This
-     request causes a line break.  The default scaling indicator is `v'.
-
-     If a vertical trap is sprung during execution of `sp', the amount
-     of vertical space after the trap is discarded.  For example, this
-
-
-          .de xxx
-          ..
-          .
-          .wh 0 xxx
-          .
-          .pl 5v
-          foo
-          .sp 2
-          bar
-          .sp 50
-          baz
-
-     results in
-
-
-          foo
-
-
-          bar
-
-          baz
-
-     The amount of discarded space is available in the number register
-     `.trunc'.
-
-     To protect `sp' against vertical traps, use the `vpt' request:
-
-
-          .vpt 0
-          .sp -3
-          .vpt 1
-
-
- -- Request: .ls [nnn]
- -- Register: \n[.L]
-     Output NNN-1 blank lines after each line of text.  With no
-     argument, `gtroff' uses the previous value before the last `ls'
-     call.
-
-
-          .ls 2    \" This causes double-spaced output
-          .ls 3    \" This causes triple-spaced output
-          .ls      \" Again double-spaced
-
-     The line spacing is associated with the current environment (*note
-     Environments::).
-
-     The read-only number register `.L' contains the current line
-     spacing setting.
-
-   *Note Changing Type Sizes::, for the requests `vs' and `pvs' as
-alternatives to `ls'.
-
- -- Escape: \x'spacing'
- -- Register: \n[.a]
-     Sometimes, extra vertical spacing is only needed occasionally, e.g.
-     to allow space for a tall construct (like an equation).  The `\x'
-     escape does this.  The escape is given a numerical argument,
-     usually enclosed in quotes (like `\x'3p''); the default scaling
-     indicator is `v'.  If this number is positive extra vertical space
-     is inserted below the current line.  A negative number adds space
-     above.  If this escape is used multiple times on the same line,
-     the maximum of the values is used.
-
-     *Note Escapes::, for details on parameter delimiting characters.
-
-     The `.a' read-only number register contains the most recent
-     (nonnegative) extra vertical line space.
-
-     Using `\x' can be necessary in combination with the `\b' escape,
-     as the following example shows.
-
-
-          This is a test with the \[rs]b escape.
-          .br
-          This is a test with the \[rs]b escape.
-          .br
-          This is a test with \b'xyz'\x'-1m'\x'1m'.
-          .br
-          This is a test with the \[rs]b escape.
-          .br
-          This is a test with the \[rs]b escape.
-
-     produces

-          This is a test with the \b escape.
-
-
- -- Request: .ns
- -- Request: .rs
- -- Register: \n[.ns]
-     Enable "no-space mode".  In this mode, spacing (either via `sp' or
-     via blank lines) is disabled.  The `bp' request to advance to the
-     next page is also disabled, except if it is accompanied by a page
-     number (see *Note Page Control::, for more information).  This
-     mode ends when actual text is output or the `rs' request is
-     encountered which ends no-space mode.  The read-only number
-     register `.ns' is set to 1 as long as no-space mode is active.
-
-     This request is useful for macros that conditionally insert
-     vertical space before the text starts (for example, a paragraph
-     macro could insert some space except when it is the first
-     paragraph after a section header).

-5.10 Tabs and Fields
-====================
-
-A tab character (ASCII char 9, EBCDIC char 5) causes a horizontal
-movement to the next tab stop (much like it did on a typewriter).
-
- -- Escape: \t
-     This escape is a non-interpreted tab character.  In copy mode
-     (*note Copy-in Mode::), `\t' is the same as a real tab character.
-
- -- Request: .ta [n1 n2 ... nn T r1 r2 ... rn]
- -- Register: \n[.tabs]
-     Change tab stop positions.  This request takes a series of tab
-     specifiers as arguments (optionally divided into two groups with
-     the letter `T') which indicate where each tab stop is to be
-     (overriding any previous settings).
-
-     Tab stops can be specified absolutely, i.e., as the distance from
-     the left margin.  For example, the following sets 6 tab stops every
-     one inch.
-
-
-          .ta 1i 2i 3i 4i 5i 6i
-
-     Tab stops can also be specified using a leading `+' which means
-     that the specified tab stop is set relative to the previous tab
-     stop.  For example, the following is equivalent to the previous
-     example.
-
-
-          .ta 1i +1i +1i +1i +1i +1i
-
-     `gtroff' supports an extended syntax to specify repeat values after
-     the `T' mark (these values are always taken as relative) - this is
-     the usual way to specify tabs set at equal intervals.  The
-     following is, yet again, the same as the previous examples.  It
-     does even more since it defines an infinite number of tab stops
-     separated by one inch.
-
-
-          .ta T 1i
-
-     Now we are ready to interpret the full syntax given at the
-     beginning: Set tabs at positions N1, N2, ..., NN and then set tabs
-     at NN+R1, NN+R2, ..., NN+RN and then at NN+RN+R1, NN+RN+R2, ...,
-     NN+RN+RN, and so on.
-
-     Example: `4c +6c T 3c 5c 2c' is equivalent to `4c 10c 13c 18c 20c
-     23c 28c 30c ...'.
-
-     The material in each tab column (i.e., the column between two tab
-     stops) may be justified to the right or left or centered in the
-     column.  This is specified by appending `R', `L', or `C' to the tab
-     specifier.  The default justification is `L'.  Example:
-
-
-          .ta 1i 2iC 3iR
-
-     Some notes:
-
-        * The default unit of the `ta' request is `m'.
-
-        * A tab stop is converted into a non-breakable horizontal
-          movement which can be neither stretched nor squeezed.  For
-          example,
-
-
-               .ds foo a\tb\tc
-               .ta T 5i
-               \*[foo]
-
-          creates a single line which is a bit longer than 10 inches (a
-          string is used to show exactly where the tab characters are).
-          Now consider the following:
-
-
-               .ds bar a\tb b\tc
-               .ta T 5i
-               \*[bar]
-
-          `gtroff' first converts the tab stops of the line into
-          unbreakable horizontal movements, then splits the line after
-          the second `b' (assuming a sufficiently short line length).
-          Usually, this isn't what the user wants.
-
-        * Superfluous tabs (i.e., tab characters which do not
-          correspond to a tab stop) are ignored except the first one
-          which delimits the characters belonging to the last tab stop
-          for right-justifying or centering.  Consider the following
-          example
-
-
-               .ds Z   foo\tbar\tfoo
-               .ds ZZ  foo\tbar\tfoobar
-               .ds ZZZ foo\tbar\tfoo\tbar
-               .ta 2i 4iR
-               \*[Z]
-               .br
-               \*[ZZ]
-               .br
-               \*[ZZZ]
-               .br
-
-          which produces the following output:
-
-
-               foo                 bar              foo
-               foo                 bar           foobar
-               foo                 bar              foobar
-
-          The first line right-justifies the second `foo' relative to
-          the tab stop.  The second line right-justifies `foobar'.  The
-          third line finally right-justifies only `foo' because of the
-          additional tab character which marks the end of the string
-          belonging to the last defined tab stop.
-
-        * Tab stops are associated with the current environment (*note
-          Environments::).
-
-        * Calling `ta' without an argument removes all tab stops.
-
-        * The start-up value of `gtroff' is `T 0.8i'.
-
-     The read-only number register `.tabs' contains a string
-     representation of the current tab settings suitable for use as an
-     argument to the `ta' request.
-
-
-          .ds tab-string \n[.tabs]
-          \*[tab-string]
-              => T120u
-
-     The `troff' version of the Plan 9 operating system uses register
-     `.S' for the same purpose.
-
- -- Request: .tc [fill-glyph]
-     Normally `gtroff' fills the space to the next tab stop with
-     whitespace.  This can be changed with the `tc' request.  With no
-     argument `gtroff' reverts to using whitespace, which is the
-     default.  The value of this "tab repetition character" is
-     associated with the current environment (*note Environments::).(1)
-     (*note Tabs and Fields-Footnote-1::)
-
- -- Request: .linetabs n
- -- Register: \n[.linetabs]
-     If N is missing or not zero, enable "line-tabs" mode, or disable
-     it otherwise (the default).  In line-tabs mode, `gtroff' computes
-     tab distances relative to the (current) output line instead of the
-     input line.
-
-     For example, the following code:
-
-
-          .ds x a\t\c
-          .ds y b\t\c
-          .ds z c
-          .ta 1i 3i
-          \*x
-          \*y
-          \*z
-
-     in normal mode, results in the output
-
-
-          a         b         c
-
-     in line-tabs mode, the same code outputs
-
-
-          a         b                   c
-
-     Line-tabs mode is associated with the current environment.  The
-     read-only register `.linetabs' is set to 1 if in line-tabs mode,
-     and 0 in normal mode.

-5.10.1 Leaders
---------------
-
-Sometimes it may may be desirable to use the `tc' request to fill a
-particular tab stop with a given glyph (for example dots in a table of
-contents), but also normal tab stops on the rest of the line.  For this
-`gtroff' provides an alternate tab mechanism, called "leaders" which
-does just that.
-
-   A leader character (character code 1) behaves similarly to a tab
-character: It moves to the next tab stop.  The only difference is that
-for this movement, the fill glyph defaults to a period character and
-not to space.
-
- -- Escape: \a
-     This escape is a non-interpreted leader character.  In copy mode
-     (*note Copy-in Mode::), `\a' is the same as a real leader
-     character.
-
- -- Request: .lc [fill-glyph]
-     Declare the "leader repetition character".(1) (*note
-     Leaders-Footnote-1::) Without an argument, leaders act the same as
-     tabs (i.e., using whitespace for filling).  `gtroff''s start-up
-     value is a dot (`.').  The value of the leader repetition
-     character is associated with the current environment (*note
-     Environments::).
-
-   For a table of contents, to name an example, tab stops may be
-defined so that the section number is one tab stop, the title is the
-second with the remaining space being filled with a line of dots, and
-then the page number slightly separated from the dots.

-"Fields" are a more general way of laying out tabular data.  A field is
-defined as the data between a pair of "delimiting characters".  It
-contains substrings which are separated by "padding characters".  The
-width of a field is the distance on the _input_ line from the position
-where the field starts to the next tab stop.  A padding character
-inserts stretchable space similar to TeX's `\hss' command (thus it can
-even be negative) to make the sum of all substring lengths plus the
-stretchable space equal to the field width.  If more than one padding
-character is inserted, the available space is evenly distributed among
-them.
-
- -- Request: .fc [delim-char [padding-char]]
-     Define a delimiting and a padding character for fields.  If the
-     latter is missing, the padding character defaults to a space
-     character.  If there is no argument at all, the field mechanism is
-     disabled (which is the default).  Note that contrary to e.g. the
-     tab repetition character, delimiting and padding characters are
-     _not_ associated to the current environment (*note Environments::).
-
-     Example:
-
-
-          .fc # ^
-          .ta T 3i
-          #foo^bar^smurf#
-          .br
-          #foo^^bar^smurf#
-
-     and here the result:
-
-
-          foo         bar          smurf
-          foo            bar       smurf

-5.11 Character Translations
-===========================
-
-The control character (`.') and the no-break control character (`'')
-can be changed with the `cc' and `c2' requests, respectively.
-
- -- Request: .cc [c]
-     Set the control character to C.  With no argument the default
-     control character `.' is restored.  The value of the control
-     character is associated with the current environment (*note
-     Environments::).
-
- -- Request: .c2 [c]
-     Set the no-break control character to C.  With no argument the
-     default control character `'' is restored.  The value of the
-     no-break control character is associated with the current
-     environment (*note Environments::).
-
- -- Request: .eo
-     Disable the escape mechanism completely.  After executing this
-     request, the backslash character `\' no longer starts an escape
-     sequence.
-
-     This request can be very helpful in writing macros since it is not
-     necessary then to double the escape character.  Here an example:
-
-
-          .\" This is a simplified version of the
-          .\" .BR request from the man macro package
-          .eo
-          .de BR
-          .  ds result \&
-          .  while (\n[.$] >= 2) \{\
-          .    as result \fB\$1\fR\$2
-          .    shift 2
-          .  \}
-          .  if \n[.$] .as result \fB\$1
-          \*[result]
-          .  ft R
-          ..
-          .ec
-
-
- -- Request: .ec [c]
-     Set the escape character to C.  With no argument the default
-     escape character `\' is restored.  It can be also used to
-     re-enable the escape mechanism after an `eo' request.
-
-     Note that changing the escape character globally will likely break
-     macro packages since `gtroff' has no mechanism to `intern' macros,
-     i.e., to convert a macro definition into an internal form which is
-     independent of its representation (TeX has this mechanism).  If a
-     macro is called, it is executed literally.
-
- -- Request: .ecs
- -- Request: .ecr
-     The `ecs' request saves the current escape character in an
-     internal register.  Use this request in combination with the `ec'
-     request to temporarily change the escape character.
-
-     The `ecr' request restores the escape character saved with `ecs'.
-     Without a previous call to `ecs', this request sets the escape
-     character to `\'.
-
- -- Escape: \\
- -- Escape: \e
- -- Escape: \E
-     Print the current escape character (which is the backslash
-     character `\' by default).
-
-     `\\' is a `delayed' backslash; more precisely, it is the default
-     escape character followed by a backslash, which no longer has
-     special meaning due to the leading escape character.  It is _not_
-     an escape sequence in the usual sense!  In any unknown escape
-     sequence `\X' the escape character is ignored and X is printed.
-     But if X is equal to the current escape character, no warning is
-     emitted.
-
-     As a consequence, only at top-level or in a diversion a backslash
-     glyph is printed; in copy-in mode, it expands to a single
-     backslash which then combines with the following character to an
-     escape sequence.
-
-     The `\E' escape differs from `\e' by printing an escape character
-     that is not interpreted in copy mode.  Use this to define strings
-     with escapes that work when used in copy mode (for example, as a
-     macro argument).  The following example defines strings to begin
-     and end a superscript:
-
-
-          .ds { \v'-.3m'\s'\En[.s]*60/100'
-          .ds } \s0\v'.3m'
-
-     Another example to demonstrate the differences between the various
-     escape sequences, using a strange escape character, `-'.
-
-
-          .ec -
-          .de xxx
-          --A'123'
-          ..
-          .xxx
-              => -A'foo'
-
-     The result is surprising for most users, expecting `1' since `foo'
-     is a valid identifier.  What has happened?  As mentioned above,
-     the leading escape character makes the following character
-     ordinary.  Written with the default escape character the sequence
-     `--' becomes `\-' - this is the minus sign.
-
-     If the escape character followed by itself is a valid escape
-     sequence, only `\E' yields the expected result:
-
-
-          .ec -
-          .de xxx
-          -EA'123'
-          ..
-          .xxx
-              => 1
-
-
- -- Escape: \.
-     Similar to `\\', the sequence `\.' isn't a real escape sequence.
-     As before, a warning message is suppressed if the escape character
-     is followed by a dot, and the dot itself is printed.
-
-
-          .de foo
-          .  nop foo
-          .
-          .  de bar
-          .    nop bar
-          \\..
-          .
-          ..
-          .foo
-          .bar
-              => foo bar
-
-     The first backslash is consumed while the macro is read, and the
-     second is swallowed while exexuting macro `foo'.
-
-   A "translation" is a mapping of an input character to an output
-glyph.  The mapping occurs at output time, i.e., the input character
-gets assigned the metric information of the mapped output character
-right before input tokens are converted to nodes (*note Gtroff
-Internals::, for more on this process).
-
- -- Request: .tr abcd...
- -- Request: .trin abcd...
-     Translate character A to glyph B, character C to glyph D, etc.  If
-     there is an odd number of arguments, the last one is translated to
-     an unstretchable space (`\ ').
-
-     The `trin' request is identical to `tr', but when you unformat a
-     diversion with `asciify' it ignores the translation.  *Note
-     Diversions::, for details about the `asciify' request.
-
-     Some notes:
-
-        * Special characters (`\(XX', `\[XXX]', `\C'XXX'', `\'', `\`',
-          `\-', `\_'), glyphs defined with the `char' request, and
-          numbered glyphs (`\N'XXX'') can be translated also.
-
-        * The `\e' escape can be translated also.
-
-        * Characters can be mapped onto the `\%' and `\~' escapes (but
-          `\%' and `\~' can't be mapped onto another glyph).
-
-        * The following characters can't be translated: space (with one
-          exception, see below), backspace, newline, leader (and `\a'),
-          tab (and `\t').
-
-        * Translations are not considered for finding the soft hyphen
-          character set with the `shc' request.
-
-        * The pair `C\&' (this is an arbitrary character C followed by
-          the zero width space character) maps this character to
-          nothing.
-
-
-               .tr a\&
-               foo bar
-                   => foo br
-
-          It is even possible to map the space character to nothing:
-
-
-               .tr aa \&
-               foo bar
-                   => foobar
-
-          As shown in the example, the space character can't be the
-          first character/glyph pair as an argument of `tr'.
-          Additionally, it is not possible to map the space character
-          to any other glyph; requests like `.tr aa x' undo `.tr aa \&'
-          instead.
-
-          If justification is active, lines are justified in spite of
-          the `empty' space character (but there is no minimal
-          distance, i.e. the space character, between words).
-
-        * After an output glyph has been constructed (this happens at
-          the moment immediately before the glyph is appended to an
-          output glyph list, either by direct output, in a macro,
-          diversion, or string), it is no longer affected by `tr'.
-
-        * Translating character to glyphs where one of them or both are
-          undefined is possible also; `tr' does not check whether the
-          entities in its argument do exist.
-
-          *Note Gtroff Internals::.
-
-        * `troff' no longer has a hard-coded dependency on Latin-1; all
-          `charXXX' entities have been removed from the font
-          description files.  This has a notable consequence which
-          shows up in warnings like `can't find character with input
-          code XXX' if the `tr' request isn't handled properly.
-
-          Consider the following translation:
-
-
-               .tr éÉ
-
-          This maps input character `é' onto glyph `É', which is
-          identical to glyph `char201'.  But this glyph intentionally
-          doesn't exist!  Instead, `\[char201]' is treated as an input
-          character entity and is by default mapped onto `\['E]', and
-          `gtroff' doesn't handle translations of translations.
-
-          The right way to write the above translation is
-
-
-               .tr é\['E]
-
-          With other words, the first argument of `tr' should be an
-          input character or entity, and the second one a glyph entity.
-
-        * Without an argument, the `tr' request is ignored.
-
- -- Request: .trnt abcd...
-     `trnt' is the same as the `tr' request except that the
-     translations do not apply to text that is transparently throughput
-     into a diversion with `\!'.  *Note Diversions::, for more
-     information.
-
-     For example,
-
-
-          .tr ab
-          .di x
-          \!.tm a
-          .di
-          .x
-
-     prints `b' to the standard error stream; if `trnt' is used instead
-     of `tr' it prints `a'.

-5.12 Troff and Nroff Mode
-=========================
-
-Originally, `nroff' and `troff' were two separate programs, the former
-for TTY output, the latter for everything else.  With GNU `troff', both
-programs are merged into one executable, sending its output to a device
-driver (`grotty' for TTY devices, `grops' for POSTSCRIPT, etc.) which
-interprets the intermediate output of `gtroff'.  For UNIX `troff' it
-makes sense to talk about "Nroff mode" and "Troff mode" since the
-differences are hardcoded.  For GNU `troff', this distinction is not
-appropriate because `gtroff' simply takes the information given in the
-font files for a particular device without handling requests specially
-if a TTY output device is used.
-
-   Usually, a macro package can be used with all output devices.
-Nevertheless, it is sometimes necessary to make a distinction between
-TTY and non-TTY devices: `gtroff' provides two built-in conditions `n'
-and `t' for the `if', `ie', and `while' requests to decide whether
-`gtroff' shall behave like `nroff' or like `troff'.
-
- -- Request: .troff
-     Make the `t' built-in condition true (and the `n' built-in
-     condition false) for `if', `ie', and `while' conditional requests.
-     This is the default if `gtroff' (_not_ `groff') is started with
-     the `-R' switch to avoid loading of the start-up files `troffrc'
-     and `troffrc-end'.  Without `-R', `gtroff' stays in troff mode if
-     the output device is not a TTY (e.g. `ps').
-
- -- Request: .nroff
-     Make the `n' built-in condition true (and the `t' built-in
-     condition false) for `if', `ie', and `while' conditional requests.
-     This is the default if `gtroff' uses a TTY output device; the
-     code for switching to nroff mode is in the file `tty.tmac' which
-     is loaded by the start-up file `troffrc'.
-
-   *Note Conditionals and Loops::, for more details on built-in
-conditions.

-5.13 Line Layout
-================
-
-The following drawing shows the dimensions which `gtroff' uses for
-placing a line of output onto the page.  They are labeled with the
-request which manipulates each dimension.
-
-
-                     -->| in |<--
-                        |<-----------ll------------>|
-                   +----+----+----------------------+----+
-                   |    :    :                      :    |
-                   +----+----+----------------------+----+
-                -->| po |<--
-                   |<--------paper width---------------->|
-
-These dimensions are:
-
-`po'
-     "Page offset" - this is the leftmost position of text on the final
-     output, defining the "left margin".
-
-`in'
-     "Indentation" - this is the distance from the left margin where
-     text is printed.
-
-`ll'
-     "Line length" - this is the distance from the left margin to right
-     margin.
-
-   A simple demonstration:
-
-
-     .ll 3i
-     This is text without indentation.
-     The line length has been set to 3\~inch.
-     .in +.5i
-     .ll -.5i
-     Now the left and right margins are both increased.
-     .in
-     .ll
-     Calling .in and .ll without parameters restore
-     the previous values.
-
-   Result:
-
-
-     This  is text without indenta-
-     tion.   The  line  length  has
-     been set to 3 inch.
-          Now   the  left  and
-          right  margins   are
-          both increased.
-     Calling  .in  and  .ll without
-     parameters restore the  previ-
-     ous values.
-
- -- Request: .po [offset]
- -- Request: .po +offset
- -- Request: .po -offset
- -- Register: \n[.o]
-     Set horizontal page offset to OFFSET (or increment or decrement
-     the current value by OFFSET).  Note that this request does not
-     cause a break, so changing the page offset in the middle of text
-     being filled may not yield the expected result.  The initial value
-     is 1i.  For TTY output devices, it is set to 0 in the startup file
-     `troffrc'; the default scaling indicator is `m' (and not `v' as
-     incorrectly documented in the original UNIX troff manual).
-
-     The current page offset can be found in the read-only number
-     register `.o'.
-
-     If `po' is called without an argument, the page offset is reset to
-     the previous value before the last call to `po'.
-
-
-          .po 3i
-          \n[.o]
-              => 720
-          .po -1i
-          \n[.o]
-              => 480
-          .po
-          \n[.o]
-              => 720
-
-
- -- Request: .in [indent]
- -- Request: .in +indent
- -- Request: .in -indent
- -- Register: \n[.i]
-     Set indentation to INDENT (or increment or decrement the current
-     value by INDENT).  This request causes a break.  Initially, there
-     is no indentation.
-
-     If `in' is called without an argument, the indentation is reset to
-     the previous value before the last call to `in'.  The default
-     scaling indicator is `m'.
-
-     The indentation is associated with the current environment (*note
-     Environments::).
-
-     If a negative indentation value is specified (which is not
-     allowed), `gtroff' emits a warning of type `range' and sets the
-     indentation to zero.
-
-     The effect of `in' is delayed until a partially collected line (if
-     it exists) is output.  A temporary indentation value is reset to
-     zero also.
-
-     The current indentation (as set by `in') can be found in the
-     read-only number register `.i'.
-
- -- Request: .ti offset
- -- Request: .ti +offset
- -- Request: .ti -offset
- -- Register: \n[.in]
-     Temporarily indent the next output line by OFFSET.  If an
-     increment or decrement value is specified, adjust the temporary
-     indentation relative to the value set by the `in' request.
-
-     This request causes a break; its value is associated with the
-     current environment (*note Environments::).  The default scaling
-     indicator is `m'.  A call of `ti' without an argument is ignored.
-
-     If the total indentation value is negative (which is not allowed),
-     `gtroff' emits a warning of type `range' and sets the temporary
-     indentation to zero.  `Total indentation' is either OFFSET if
-     specified as an absolute value, or the temporary plus normal
-     indentation, if OFFSET is given as a relative value.
-
-     The effect of `ti' is delayed until a partially collected line (if
-     it exists) is output.
-
-     The read-only number register `.in' is the indentation that applies
-     to the current output line.
-
-     The difference between `.i' and `.in' is that the latter takes
-     into account whether a partially collected line still uses the old
-     indentation value or a temporary indentation value is active.
-
- -- Request: .ll [length]
- -- Request: .ll +length
- -- Request: .ll -length
- -- Register: \n[.l]
- -- Register: \n[.ll]
-     Set the line length to LENGTH (or increment or decrement the
-     current value by LENGTH).  Initially, the line length is set to
-     6.5i.  The effect of `ll' is delayed until a partially collected
-     line (if it exists) is output.  The default scaling indicator is
-     `m'.
-
-     If `ll' is called without an argument, the line length is reset to
-     the previous value before the last call to `ll'.  If a negative
-     line length is specified (which is not allowed), `gtroff' emits a
-     warning of type `range' and sets the line length to zero.
-
-     The line length is associated with the current environment (*note
-     Environments::).
-
-     The current line length (as set by `ll') can be found in the
-     read-only number register `.l'.  The read-only number register
-     `.ll' is the line length that applies to the current output line.
-
-     Similar to `.i' and `.in', the difference between `.l' and `.ll'
-     is that the latter takes into account whether a partially
-     collected line still uses the old line length value.

-5.14 Line Control
-=================
-
-It is important to understand how `gtroff' handles input and output
-lines.
-
-   Many escapes use positioning relative to the input line.  For
-example, this
-
-
-     This is a \h'|1.2i'test.
-
-     This is a
-     \h'|1.2i'test.
-
-produces
-
-
-     This is a   test.
-
-     This is a             test.
-
-   The main usage of this feature is to define macros which act exactly
-at the place where called.
-
-
-     .\" A simple macro to underline a word
-     .de underline
-     .  nop \\$1\l'|0\[ul]'
-     ..
-
-In the above example, `|0' specifies a negative distance from the
-current position (at the end of the just emitted argument `\$1') back
-to the beginning of the input line.  Thus, the `\l' escape draws a line
-from right to left.
-
-   `gtroff' makes a difference between input and output line
-continuation; the latter is also called "interrupting" a line.
-
- -- Escape: \<RET>
- -- Escape: \c
- -- Register: \n[.int]
-     Continue a line.  `\<RET>' (this is a backslash at the end of a
-     line immediately followed by a newline) works on the input level,
-     suppressing the effects of the following newline in the input.
-
-
-          This is a \
-          .test
-              => This is a .test
-
-     The `|' operator is also affected.
-
-     `\c' works on the output level.  Anything after this escape on the
-     same line is ignored, except `\R' which works as usual.  Anything
-     before `\c' on the same line will be appended to the current
-     partial output line.  The next non-command line after an
-     interrupted line counts as a new input line.
-
-     The visual results depend on whether no-fill mode is active.
-
-        * If no-fill mode is active (using the `nf' request), the next
-          input text line after `\c' will be handled as a continuation
-          of the same input text line.
-
-
-               .nf
-               This is a \c
-               test.
-                   => This is a test.
-
-        * If fill mode is active (using the `fi' request), a word
-          interrupted with `\c' will be continued with the text on the
-          next input text line, without an intervening space.
-
-
-               This is a te\c
-               st.
-                   => This is a test.
-
-
-     Note that an intervening control line which causes a break is
-     stronger than `\c', flushing out the current partial line in the
-     usual way.
-
-     The `.int' register contains a positive value if the last output
-     line was interrupted with `\c'; this is associated with the
-     current environment (*note Environments::).

-5.15 Page Layout
-================
-
-`gtroff' provides some very primitive operations for controlling page
-layout.
-
- -- Request: .pl [length]
- -- Request: .pl +length
- -- Request: .pl -length
- -- Register: \n[.p]
-     Set the "page length" to LENGTH (or increment or decrement the
-     current value by LENGTH).  This is the length of the physical
-     output page.  The default scaling indicator is `v'.
-
-     The current setting can be found in the read-only number register
-     `.p'.
-
-     Note that this only specifies the size of the page, not the top and
-     bottom margins.  Those are not set by `gtroff' directly.  *Note
-     Traps::, for further information on how to do this.
-
-     Negative `pl' values are possible also, but not very useful: No
-     trap is sprung, and each line is output on a single page (thus
-     suppressing all vertical spacing).
-
-     If no argument or an invalid argument is given, `pl' sets the page
-     length to 11i.
-
-   `gtroff' provides several operations which help in setting up top
-and bottom titles (or headers and footers).
-
- -- Request: .tl 'left'center'right'
-     Print a "title line".  It consists of three parts: a left
-     justified portion, a centered portion, and a right justified
-     portion.  The argument separator `'' can be replaced with any
-     character not occurring in the title line.  The `%' character is
-     replaced with the current page number.  This character can be
-     changed with the `pc' request (see below).
-
-     Without argument, `tl' is ignored.
-
-     Some notes:
-
-        * A title line is not restricted to the top or bottom of a page.
-
-        * `tl' prints the title line immediately, ignoring a partially
-          filled line (which stays untouched).
-
-        * It is not an error to omit closing delimiters.  For example,
-          `.tl /foo' is equivalent to `.tl /foo///': It prints a title
-          line with the left justified word `foo'; the centered and
-          right justfied parts are empty.
-
-        * `tl' accepts the same parameter delimiting characters as the
-          `\A' escape; see *Note Escapes::.
-
- -- Request: .lt [length]
- -- Request: .lt +length
- -- Request: .lt -length
- -- Register: \n[.lt]
-     The title line is printed using its own line length, which is
-     specified (or incremented or decremented) with the `lt' request.
-     Initially, the title line length is set to 6.5i.  If a negative
-     line length is specified (which is not allowed), `gtroff' emits a
-     warning of type `range' and sets the title line length to zero.
-     The default scaling indicator is `m'.  If `lt' is called without
-     an argument, the title length is reset to the previous value
-     before the last call to `lt'.
-
-     The current setting of this is available in the `.lt' read-only
-     number register; it is associated with the current environment
-     (*note Environments::).
-
- -- Request: .pn page
- -- Request: .pn +page
- -- Request: .pn -page
- -- Register: \n[.pn]
-     Change (increase or decrease) the page number of the _next_ page.
-     The only argument is the page number; the request is ignored
-     without a parameter.
-
-     The read-only number register `.pn' contains the number of the next
-     page: either the value set by a `pn' request, or the number of the
-     current page plus 1.
-
- -- Request: .pc [char]
-     Change the page number character (used by the `tl' request) to a
-     different character.  With no argument, this mechanism is disabled.
-     Note that this doesn't affect the number register `%'.
-
-   *Note Traps::.
-

-File: groff,  Node: Page Control,  Next: Fonts and Symbols,  Prev: Page Layout,  Up: gtroff Reference
-
-5.16 Page Control
-=================
-
- -- Request: .bp [page]
- -- Request: .bp +page
- -- Request: .bp -page
- -- Register: \n[%]
-     Stop processing the current page and move to the next page.  This
-     request causes a break.  It can also take an argument to set
-     (increase, decrease) the page number of the next page (which
-     actually becomes the current page after `bp' has finished).  The
-     difference between `bp' and `pn' is that `pn' does not cause a
-     break or actually eject a page.  *Note Page Layout::.
-
-
-          .de newpage                         \" define macro
-          'bp                                 \" begin page
-          'sp .5i                             \" vertical space
-          .tl 'left top'center top'right top' \" title
-          'sp .3i                             \" vertical space
-          ..                                  \" end macro
-
-     `bp' has no effect if not called within the top-level diversion
-     (*note Diversions::).
-
-     The read-write register `%' holds the current page number.
-
-     The number register `.pe' is set to 1 while `bp' is active.  *Note
-     Page Location Traps::.
-
- -- Request: .ne [space]
-     It is often necessary to force a certain amount of space before a
-     new page occurs.  This is most useful to make sure that there is
-     not a single "orphan" line left at the bottom of a page.  The `ne'
-     request ensures that there is a certain distance, specified by the
-     first argument, before the next page is triggered (see *Note
-     Traps::, for further information).  The default scaling indicator
-     for `ne' is `v'; the default value of SPACE is 1v if no argument
-     is given.
-
-     For example, to make sure that no fewer than 2 lines get orphaned,
-     do the following before each paragraph:
-
-
-          .ne 2
-          text text text
-
-     `ne' will then automatically cause a page break if there is space
-     for one line only.
-
- -- Request: .sv [space]
- -- Request: .os
-     `sv' is similar to the `ne' request; it reserves the specified
-     amount of vertical space.  If the desired amount of space exists
-     before the next trap (or the bottom page boundary if no trap is
-     set), the space is output immediately (ignoring a partially filled
-     line which stays untouched).  If there is not enough space, it is
-     stored for later output via the `os' request.  The default value
-     is 1v if no argument is given; the default scaling indicator is
-     `v'.
-
-     Both `sv' and `os' ignore no-space mode.  While the `sv' request
-     allows negative values for SPACE, `os' will ignore them.
-
- -- Register: \n[nl]
-     This register contains the current vertical position.  If the
-     vertical position is zero and the top of page transition hasn't
-     happened yet, `nl' is set to negative value.  `gtroff' itself does
-     this at the very beginning of a document before anything has been
-     printed, but the main usage is to plant a header trap on a page if
-     this page has already started.
-
-     Consider the following:
-
-
-          .de xxx
-          .  sp
-          .  tl ''Header''
-          .  sp
-          ..
-          .
-          First page.
-          .bp
-          .wh 0 xxx
-          .nr nl (-1)
-          Second page.
-
-     Result:
-
-
-          First page.
-
-          ...
-
-                                       Header
-
-          Second page.
-
-          ...
-
-     Without resetting `nl' to a negative value, the just planted trap
-     would be active beginning with the _next_ page, not the current
-     one.
-
-     *Note Diversions::, for a comparison with the `.h' and `.d'
-     registers.

-5.17 Fonts and Symbols
-======================
-
-`gtroff' can switch fonts at any point in the text.
-
-   The basic set of fonts is `R', `I', `B', and `BI'.  These are Times
-Roman, Italic, Bold, and Bold Italic.  For non-TTY devices, there is
-also at least one symbol font which contains various special symbols
-(Greek, mathematics).

-5.17.1 Changing Fonts
----------------------
-
- -- Request: .ft [font]
- -- Escape: \ff
- -- Escape: \f(fn
- -- Escape: \f[font]
- -- Register: \n[.sty]
-     The `ft' request and the `\f' escape change the current font to
-     FONT (one-character name F, two-character name FN).
-
-     If FONT is a style name (as set with the `sty' request or with the
-     `styles' command in the `DESC' file), use it within the current
-     font family (as set with the `fam' request, `\F' escape, or with
-     the `family' command in the `DESC' file).
-
-     With no argument or using `P' as an argument, `.ft' switches to
-     the previous font.  Use `\f[]' to do this with the escape.  The
-     old syntax forms `\fP' or `\f[P]' are also supported.
-
-     Fonts are generally specified as upper-case strings, which are
-     usually 1 to 4 characters representing an abbreviation or acronym
-     of the font name.  This is no limitation, just a convention.
-
-     The example below produces two identical lines.
-
-
-          eggs, bacon,
-          .ft B
-          spam
-          .ft
-          and sausage.
-
-          eggs, bacon, \fBspam\fP and sausage.
-
-     Note that `\f' doesn't produce an input token in `gtroff'.  As a
-     consequence, it can be used in requests like `mc' (which expects a
-     single character as an argument) to change the font on the fly:
-
-
-          .mc \f[I]x\f[]
-
-     The current style name is available in the read-only number
-     register `.sty' (this is a string-valued register); if the current
-     font isn't a style, the empty string is returned.  It is
-     associated with the current environment.
-
-     *Note Font Positions::, for an alternative syntax.
-
- -- Request: .ftr f [g]
-     Translate font F to font G.  Whenever a font named F is referred
-     to in a `\f' escape sequence, in the `F' and `S' conditional
-     operators, or in the `ft', `ul', `bd', `cs', `tkf', `special',
-     `fspecial', `fp', or `sty' requests, font G is used.  If G is
-     missing or equal to F the translation is undone.

-
-5.17.2 Font Families
---------------------
-
-Due to the variety of fonts available, `gtroff' has added the concept
-of "font families" and "font styles".  The fonts are specified as the
-concatenation of the font family and style.  Specifying a font without
-the family part causes `gtroff' to use that style of the current family.
-
-   Currently, fonts for the devices `-Tps', `-Tdvi', `-Tlj4', `-Tlbp',
-and the X11 fonts are set up to this mechanism.  By default, `gtroff'
-uses the Times family with the four styles `R', `I', `B', and `BI'.
-
-   This way, it is possible to use the basic four fonts and to select a
-different font family on the command line (*note Groff Options::).
-
- -- Request: .fam [family]
- -- Register: \n[.fam]
- -- Escape: \Ff
- -- Escape: \F(fm
- -- Escape: \F[family]
- -- Register: \n[.fn]
-     Switch font family to FAMILY (one-character name F, two-character
-     name FM).  If no argument is given, switch back to the previous
-     font family.  Use `\F[]' to do this with the escape.  Note that
-     `\FP' doesn't work; it selects font family `P' instead.
-
-     The value at start-up is `T'.  The current font family is
-     available in the read-only number register `.fam' (this is a
-     string-valued register); it is associated with the current
-     environment.
-
-
-          spam,
-          .fam H    \" helvetica family
-          spam,     \" used font is family H + style R = HR
-          .ft B     \" family H + style B = font HB
-          spam,
-          .fam T    \" times family
-          spam,     \" used font is family T + style B = TB
-          .ft AR    \" font AR (not a style)
-          baked beans,
-          .ft R     \" family T + style R = font TR
-          and spam.
-
-     Note that `\F' doesn't produce an input token in `gtroff'.  As a
-     consequence, it can be used in requests like `mc' (which expects a
-     single character as an argument) to change the font family on the
-     fly:
-
-
-          .mc \F[P]x\F[]
-
-     The `.fn' register contains the current "real font name" of the
-     current font.  This is a string-valued register.  If the current
-     font is a style, the value of `\n[.fn]' is the proper
-     concatenation of family and style name.
-
- -- Request: .sty n style
-     Associate STYLE with font position N.  A font position can be
-     associated either with a font or with a style.  The current font
-     is the index of a font position and so is also either a font or a
-     style.  If it is a style, the font that is actually used is the
-     font which name is the concatenation of the name of the current
-     family and the name of the current style.  For example, if the
-     current font is 1 and font position 1 is associated with style `R'
-     and the current font family is `T', then font `TR' will be used.
-     If the current font is not a style, then the current family is
-     ignored.  If the requests `cs', `bd', `tkf', `uf', or `fspecial'
-     are applied to a style, they will instead be applied to the member
-     of the current family corresponding to that style.
-
-     N must be a non-negative integer value.
-
-     The default family can be set with the `-f' option (*note Groff
-     Options::).  The `styles' command in the `DESC' file controls
-     which font positions (if any) are initially associated with styles
-     rather than fonts.  For example, the default setting for
-     POSTSCRIPT fonts
-
-
-          styles R I B BI
-
-     is equivalent to
-
-
-          .sty 1 R
-          .sty 2 I
-          .sty 3 B
-          .sty 4 BI
-
-     `fam' and `\F' always check whether the current font position is
-     valid; this can give surprising results if the current font
-     position is associated with a style.
-
-     In the following example, we want to access the POSTSCRIPT font
-     `FooBar' from the font family `Foo':
-
-
-          .sty \n[.fp] Bar
-          .fam Foo
-              => warning: can't find font `FooR'
-
-     The default font position at start-up is 1; for the POSTSCRIPT
-     device, this is associated with style `R', so `gtroff' tries to
-     open `FooR'.
-
-     A solution to this problem is to use a dummy font like the
-     following:
-
-
-          .fp 0 dummy TR    \" set up dummy font at position 0
-          .sty \n[.fp] Bar  \" register style `Bar'
-          .ft 0             \" switch to font at position 0
-          .fam Foo          \" activate family `Foo'
-          .ft Bar           \" switch to font `FooBar'
-
-     *Note Font Positions::.

-
-5.17.3 Font Positions
----------------------
-
-For the sake of old phototypesetters and compatibility with old versions
-of `troff', `gtroff' has the concept of font "positions", on which
-various fonts are mounted.
-
- -- Request: .fp pos font [external-name]
- -- Register: \n[.f]
- -- Register: \n[.fp]
-     Mount font FONT at position POS (which must be a non-negative
-     integer).  This numeric position can then be referred to with font
-     changing commands.  When `gtroff' starts it is using font
-     position 1 (which must exist; position 0 is unused usually at
-     start-up).
-
-     The current font in use, as a font position, is available in the
-     read-only number register `.f'.  This can be useful to remember the
-     current font for later recall.  It is associated with the current
-     environment (*note Environments::).
-
-
-          .nr save-font \n[.f]
-          .ft B
-          ... text text text ...
-          .ft \n[save-font]
-
-     The number of the next free font position is available in the
-     read-only number register `.fp'.  This is useful when mounting a
-     new font, like so:
-
-
-          .fp \n[.fp] NEATOFONT
-
-     Fonts not listed in the `DESC' file are automatically mounted on
-     the next available font position when they are referenced.  If a
-     font is to be mounted explicitly with the `fp' request on an unused
-     font position, it should be mounted on the first unused font
-     position, which can be found in the `.fp' register.  Although
-     `gtroff' does not enforce this strictly, it is not allowed to
-     mount a font at a position whose number is much greater (approx.
-     1000 positions) than that of any currently used position.
-
-     The `fp' request has an optional third argument.  This argument
-     gives the external name of the font, which is used for finding the
-     font description file.  The second argument gives the internal
-     name of the font which is used to refer to the font in `gtroff'
-     after it has been mounted.  If there is no third argument then the
-     internal name is used as the external name.  This feature makes it
-     possible to use fonts with long names in compatibility mode.
-
-   Both the `ft' request and the `\f' escape have alternative syntax
-forms to access font positions.
-
- -- Request: .ft nnn
- -- Escape: \fn
- -- Escape: \f(nn
- -- Escape: \f[nnn]
-     Change the current font position to NNN (one-digit position N,
-     two-digit position NN), which must be a non-negative integer.
-
-     If NNN is associated with a style (as set with the `sty' request
-     or with the `styles' command in the `DESC' file), use it within
-     the current font family (as set with the `fam' request, the `\F'
-     escape, or with the `family' command in the `DESC' file).
-
-
-          this is font 1
-          .ft 2
-          this is font 2
-          .ft                   \" switch back to font 1
-          .ft 3
-          this is font 3
-          .ft
-          this is font 1 again

-5.17.4 Using Symbols
---------------------
-
-A "glyph" is a graphical representation of a "character".  While a
-character is an abstract entity containing semantic information, a
-glyph is something which can be actually seen on screen or paper.  It
-is possible that a character has multiple glyph representation forms
-(for example, the character `A' can be either written in a roman or an
-italic font, yielding two different glyphs); sometimes more than one
-character maps to a single glyph (this is a "ligature" - the most
-common is `fi').
-
-   A "symbol" is simply a named glyph.  Within `gtroff', all glyph
-names of a particular font are defined in its font file.  If the user
-requests a glyph not available in this font, `gtroff' looks up an
-ordered list of "special fonts".  By default, the POSTSCRIPT output
-device supports the two special fonts `SS' (slanted symbols) and `S'
-(symbols) (the former is looked up before the latter).  Other output
-devices use different names for special fonts.  Fonts mounted with the
-`fonts' keyword in the `DESC' file are globally available.  To install
-additional special fonts locally (i.e. for a particular font), use the
-`fspecial' request.
-
-   Here the exact rules how `gtroff' searches a given symbol:
-
-   * If the symbol has been defined with the `char' request, use it.
-     This hides a symbol with the same name in the current font.
-
-   * Check the current font.
-
-   * If the symbol has been defined with the `fchar' request, use it.
-
-   * Check whether the current font has a font-specific list of special
-     fonts; test all fonts in the order of appearance in the last
-     `fspecial' call if appropriate.
-
-   * If the symbol has been defined with the `fschar' request for the
-     current font, use it.
-
-   * Check all fonts in the order of appearance in the last `special'
-     call.
-
-   * If the symbol has been defined with the `schar' request, use it.
-
-   * As a last resort, consult all fonts loaded up to now for special
-     fonts and check them, starting with the lowest font number.  Note
-     that this can sometimes lead to surprising results since the
-     `fonts' line in the `DESC' file often contains empty positions
-     which are filled later on.  For example, consider the following:
-
-
-          fonts 3 0 0 FOO
-
-     This mounts font `foo' at font position 3.  We assume that `FOO'
-     is a special font, containing glyph `foo', and that no font has
-     been loaded yet.  The line
-
-
-          .fspecial BAR BAZ
-
-     makes font `BAZ' special only if font `BAR' is active.  We further
-     assume that `BAZ' is really a special font, i.e., the font
-     description file contains the `special' keyword, and that it also
-     contains glyph `foo' with a special shape fitting to font `BAR'.
-     After executing `fspecial', font `BAR' is loaded at font
-     position 1, and `BAZ' at position 2.
-
-     We now switch to a new font `XXX', trying to access glyph `foo'
-     which is assumed to be missing.  There are neither font-specific
-     special fonts for `XXX' nor any other fonts made special with the
-     `special' request, so `gtroff' starts the search for special fonts
-     in the list of already mounted fonts, with increasing font
-     positions.  Consequently, it finds `BAZ' before `FOO' even for
-     `XXX' which is not the intended behaviour.
-
-   *Note Font Files::, and *Note Special Fonts::, for more details.
-
-   The list of available symbols is device dependent; see the
-`groff_char(7)' man page for a complete list of all glyphs.  For
-example, say
-
-
-     man -Tdvi groff_char > groff_char.dvi
-
-for a list using the default DVI fonts (not all versions of the `man'
-program support the `-T' option).  If you want to use an additional
-macro package to change the used fonts, `groff' must be called directly:
-
-
-     groff -Tdvi -mec -man groff_char.7 > groff_char.dvi
-
-   Glyph names not listed in groff_char(7) are derived algorithmically,
-using a simplified version of the Adobe Glyph List (AGL) algorithm
-which is described in
-`http://partners.adobe.com/asn/tech/type/unicodegn.jsp'.  The (frozen)
-set of glyph names which can't be derived algorithmically is called
-"groff glyph list (GGL)".
-
-   * A glyph for Unicode character U+XXXX[X[X]] which is not a
-     composite character will be named `uXXXX[X[X]]'.  X must be an
-     uppercase hexadecimal digit.  Examples: `u1234', `u008E',
-     `u12DB8'.  The largest Unicode value is 0x10FFFF.  There must be at
-     least four `X' digits; if necessary, add leading zeroes (after the
-     `u').  No zero padding is allowed for character codes greater than
-     0xFFFF.  Surrogates (i.e., Unicode values greater than 0xFFFF
-     represented with character codes from the surrogate area
-     U+D800-U+DFFF) are not allowed too.
-
-   * A glyph representing more than a single input character will be
-     named
-
-          `u' COMPONENT1 `_' COMPONENT2 `_' COMPONENT3 ...
-
-     Example: `u0045_0302_0301'.
-
-     For simplicity, all Unicode characters which are composites must be
-     decomposed maximally (this is normalization form D in the Unicode
-     standard); for example, `u00CA_0301' is not a valid glyph name
-     since U+00CA (LATIN CAPITAL LETTER E WITH CIRCUMFLEX) can be
-     further decomposed into U+0045 (LATIN CAPITAL LETTER E) and U+0302
-     (COMBINING CIRCUMFLEX ACCENT).  `u0045_0302_0301' is thus the
-     glyph name for U+1EBE, LATIN CAPITAL LETTER E WITH CIRCUMFLEX AND
-     ACUTE.
-
-   * groff maintains a table to decompose all algorithmically derived
-     glyph names which are composites itself.  For example, `u0100'
-     (LATIN LETTER A WITH MACRON) will be automatically decomposed into
-     `u0041_0304'.  Additionally, a glyph name of the GGL is preferred
-     to an algorithmically derived glyph name; groff also automatically
-     does the mapping.  Example: The glyph `u0045_0302' will be mapped
-     to `^E'.
-
-   * glyph names of the GGL can't be used in composite glyph names; for
-     example, `^E_u0301' is invalid.
-
- -- Escape: \(nm
- -- Escape: \[name]
- -- Escape: \[component1 component2 ...]
-     Insert a symbol NAME (two-character name NM) or a composite glyph
-     with component glyphs COMPONENT1, COMPONENT2, .... There is no
-     special syntax for one-character names - the natural form `\N'
-     would collide with escapes.(1) (*note Using Symbols-Footnote-1::)
-
-     If NAME is undefined, a warning of type `char' is generated, and
-     the escape is ignored.  *Note Debugging::, for information about
-     warnings.
-
-     groff resolves `\[...]' with more than a single component as
-     follows:
-
-        * Any component which is found in the GGL will be converted to
-          the `uXXXX' form.
-
-        * Any component `uXXXX' which is found in the list of
-          decomposable glyphs will be decomposed.
-
-        * The resulting elements are then concatenated with `_'
-          inbetween, dropping the leading `u' in all elements but the
-          first.
-
-     No check for the existence of any component (similar to `tr'
-     request) will be done.
-
-     Examples:
-
-    `\[A ho]'
-          `A' maps to `u0041', `ho' maps to `u02DB', thus the final
-          glyph name would be `u0041_02DB'.  Note this is not the
-          expected result: The ogonek glyph `ho' is a spacing ogonek,
-          but for a proper composite a non-spacing ogonek (U+0328) is
-          necessary.  Looking into the file `composite.tmac' one can
-          find `.composite ho u0328' which changes the mapping of `ho'
-          while a composite glyph name is constructed, causing the
-          final glyph name to be `u0041_0328'.
-
-    `\[^E u0301]'
-    `\[^E aa]'
-    `\[E a^ aa]'
-    `\[E ^ ']'
-          `^E' maps to `u0045_0302', thus the final glyph name is
-          `u0045_0302_0301' in all forms (assuming proper calls of the
-          `composite' request).
-
-     It is not possible to define glyphs with names like `A ho' within
-     a groff font file.  This is not really a limitation; instead, you
-     have to define `u0041_0328'.
-
- -- Escape: \C'xxx'
-     Typeset the glyph named XXX.(2) (*note Using Symbols-Footnote-2::)
-     Normally it is more convenient to use `\[XXX]', but `\C' has the
-     advantage that it is compatible with newer versions of AT&T
-     `troff' and is available in compatibility mode.
-
- -- Request: .composite from to
-     Map glyph name FROM to glyph name TO if it is used in `\[...]'
-     with more than one component.  See above for examples.
-
-     This mapping is based on glyph names only; no check for the
-     existence of either glyph is done.
-
-     A set of default mappings for many accents can be found in the file
-     `composite.tmac' which is loaded at start-up.
-
- -- Escape: \N'n'
-     Typeset the glyph with code N in the current font (`n' is *not*
-     the input character code).  The number N can be any non-negative
-     decimal integer.  Most devices only have glyphs with codes between
-     0 and 255; the Unicode output device uses codes in the range
-     0-65535.  If the current font does not contain a glyph with that
-     code, special fonts are _not_ searched.  The `\N' escape sequence
-     can be conveniently used in conjunction with the `char' request:
-
-
-          .char \[phone] \f[ZD]\N'37'
-
-     The code of each glyph is given in the fourth column in the font
-     description file after the `charset' command.  It is possible to
-     include unnamed glyphs in the font description file by using a
-     name of `---'; the `\N' escape sequence is the only way to use
-     these.
-
-     No kerning is applied to glyphs accessed with `\N'.
-
-   Some escape sequences directly map onto special glyphs.
-
- -- Escape: \'
-     This is a backslash followed by the apostrophe character, ASCII
-     character `0x27' (EBCDIC character `0x7D').  The same as `\[aa]',
-     the acute accent.
-
- -- Escape: \`
-     This is a backslash followed by ASCII character `0x60' (EBCDIC
-     character `0x79' usually).  The same as `\[ga]', the grave accent.
-
- -- Escape: \-
-     This is the same as `\[-]', the minus sign in the current font.
-
- -- Request: .cflags n c1 c2 ...
-     Input characters and symbols have certain properties associated
-     with it.(3) (*note Using Symbols-Footnote-3::)  These properties
-     can be modified with the `cflags' request.  The first argument is
-     the sum of the desired flags and the remaining arguments are the
-     characters or symbols to have those properties.  It is possible to
-     omit the spaces between the characters or symbols.
-
-    `1'
-          The character ends sentences (initially characters `.?!' have
-          this property).
-
-    `2'
-          Lines can be broken before the character (initially no
-          characters have this property).
-
-    `4'
-          Lines can be broken after the character (initially the
-          character `-' and the symbols `\[hy]' and `\[em]' have this
-          property).
-
-    `8'
-          The character overlaps horizontally if used as a horizontal
-          line building element.  Initially the symbols `\[ul]',
-          `\[rn]', `\[ru]', `\[radicalex]', and `\[sqrtex]' have this
-          property.
-
-    `16'
-          The character overlaps vertically if used as vertical line
-          building element.  Initially symbol `\[br]' has this property.
-
-    `32'
-          An end-of-sentence character followed by any number of
-          characters with this property is treated as the end of a
-          sentence if followed by a newline or two spaces; in other
-          words the character is "transparent" for the purposes of
-          end-of-sentence recognition - this is the same as having a
-          zero space factor in TeX (initially characters `"')]*' and
-          the symbols `\[dg]' and `\[rq]' have this property).
-
- -- Request: .char g [string]
- -- Request: .fchar g [string]
- -- Request: .fschar f g [string]
- -- Request: .schar g [string]
-     Define a new glyph G to be STRING (which can be empty).(4) (*note
-     Using Symbols-Footnote-4::)  Every time glyph G needs to be
-     printed, STRING is processed in a temporary environment and the
-     result is wrapped up into a single object.  Compatibility mode is
-     turned off and the escape character is set to `\' while STRING is
-     being processed.  Any emboldening, constant spacing or track
-     kerning is applied to this object rather than to individual
-     characters in STRING.
-
-     A glyph defined by these requests can be used just like a normal
-     glyph provided by the output device.  In particular, other
-     characters can be translated to it with the `tr' or `trin'
-     requests; it can be made the leader character by the `lc' request;
-     repeated patterns can be drawn with the glyph using the `\l' and
-     `\L' escape sequences; words containing the glyph can be
-     hyphenated correctly if the `hcode' request is used to give the
-     glyph's symbol a hyphenation code.
-
-     There is a special anti-recursion feature: Use of `g' within the
-     glyph's definition is handled like normal characters and symbols
-     not defined with `char'.
-
-     Note that the `tr' and `trin' requests take precedence if `char'
-     accesses the same symbol.
-
-
-          .tr XY
-          X
-              => Y
-          .char X Z
-          X
-              => Y
-          .tr XX
-          X
-              => Z
-
-     The `fchar' request defines a fallback glyph: `gtroff' only checks
-     for glyphs defined with `fchar' if it cannot find the glyph in the
-     current font.  `gtroff' carries out this test before checking
-     special fonts.
-
-     `fschar' defines a fallback glyph for font F: `gtroff' checks for
-     glyphs defined with `fschar' after the list of fonts declared as
-     font-specific special fonts with the `fspecial' request, but
-     before the list of fonts declared as global special fonts with the
-     `special' request.
-
-     Finally, the `schar' request defines a global fallback glyph:
-     `gtroff' checks for glyphs defined with `schar' after the list of
-     fonts declared as global special fonts with the `special' request,
-     but before the already mounted special fonts.
-
-     *Note Using Symbols::, for a detailed description of the glyph
-     searching mechanism in `gtroff'.
-
- -- Request: .rchar c1 c2 ...
- -- Request: .rfschar f c1 c2 ...
-     Remove the definitions of glyphs C1, C2, ....  This undoes the
-     effect of a `char', `fchar', or `schar' request.
-
-     It is possible to omit the whitespace between arguments.
-
-     The request `rfschar' removes glyph definitions defined with
-     `fschar' for glyph f.

-   (1) Note that a one-character symbol is not the same as an input
-character, i.e., the character `a' is not the same as `\[a]'.  By
-default, `groff' defines only a single one-character symbol, `\[-]'; it
-is usually accessed as `\-'.  On the other hand, `gtroff' has the
-special feature that `\[charXXX]' is the same as the input character
-with character code XXX.  For example, `\[char97]' is identical to the
-letter `a' if ASCII encoding is active.
-
-   (2) `\C' is actually a misnomer since it accesses an output glyph.
-
-   (3) Note that the output glyphs themselves don't have such
-properties.  For `gtroff', a glyph is a numbered box with a given
-width, depth, and height, nothing else.  All manipulations with the
-`cflags' request work on the input level.
-
-   (4) `char' is a misnomer since an output glyph is defined.

-5.17.5 Special Fonts
---------------------
-
-Special fonts are those that `gtroff' searches when it cannot find the
-requested glyph in the current font.  The Symbol font is usually a
-special font.
-
-   `gtroff' provides the following two requests to add more special
-fonts.  *Note Using Symbols::, for a detailed description of the glyph
-searching mechanism in `gtroff'.
-
-   Usually, only non-TTY devices have special fonts.
-
- -- Request: .special [s1 s2 ...]
- -- Request: .fspecial f [s1 s2 ...]
-     Use the `special' request to define special fonts.  Initially, this
-     list is empty.
-
-     Use the `fspecial' request to designate special fonts only when
-     font F is active.  Initially, this list is empty.
-
-     Previous calls to `special' or `fspecial' are overwritten; without
-     arguments, the particular list of special fonts is set to empty.
-     Special fonts are searched in the order they appear as arguments.
-
-     All fonts which appear in a call to `special' or `fspecial' are
-     loaded.
-
-     *Note Using Symbols::, for the exact search order of glyphs.

-5.17.6 Artificial Fonts
------------------------
-
-There are a number of requests and escapes for artificially creating
-fonts.  These are largely vestiges of the days when output devices did
-not have a wide variety of fonts, and when `nroff' and `troff' were
-separate programs.  Most of them are no longer necessary in GNU
-`troff'.  Nevertheless, they are supported.
-
- -- Escape: \H'height'
- -- Escape: \H'+height'
- -- Escape: \H'-height'
- -- Register: \n[.height]
-     Change (increment, decrement) the height of the current font, but
-     not the width.  If HEIGHT is zero, restore the original height.
-     Default scaling indicator is `z'.
-
-     The read-only number register `.height' contains the font height as
-     set by `\H'.
-
-     Currently, only the `-Tps' device supports this feature.
-
-     Note that `\H' doesn't produce an input token in `gtroff'.  As a
-     consequence, it can be used in requests like `mc' (which expects a
-     single character as an argument) to change the font on the fly:
-
-
-          .mc \H'+5z'x\H'0'
-
-     In compatibility mode, `gtroff' behaves differently:  If an
-     increment or decrement is used, it is always taken relative to the
-     current point size and not relative to the previously selected font
-     height.  Thus,
-
-
-          .cp 1
-          \H'+5'test \H'+5'test
-
-     prints the word `test' twice with the same font height (five
-     points larger than the current font size).
-
- -- Escape: \S'slant'
- -- Register: \n[.slant]
-     Slant the current font by SLANT degrees.  Positive values slant to
-     the right.  Only integer values are possible.
-
-     The read-only number register `.slant' contains the font slant as
-     set by `\S'.
-
-     Currently, only the `-Tps' device supports this feature.
-
-     Note that `\S' doesn't produce an input token in `gtroff'.  As a
-     consequence, it can be used in requests like `mc' (which expects a
-     single character as an argument) to change the font on the fly:
-
-
-          .mc \S'20'x\S'0'
-
-     This request is incorrectly documented in the original UNIX troff
-     manual; the slant is always set to an absolute value.
-
- -- Request: .ul [lines]
-     The `ul' request normally underlines subsequent lines if a TTY
-     output device is used.  Otherwise, the lines are printed in italics
-     (only the term `underlined' is used in the following).  The single
-     argument is the number of input lines to be underlined; with no
-     argument, the next line is underlined.  If LINES is zero or
-     negative, stop the effects of `ul' (if it was active).  Requests
-     and empty lines do not count for computing the number of underlined
-     input lines, even if they produce some output like `tl'.  Lines
-     inserted by macros (e.g. invoked by a trap) do count.
-
-     At the beginning of `ul', the current font is stored and the
-     underline font is activated.  Within the span of a `ul' request,
-     it is possible to change fonts, but after the last line affected by
-     `ul' the saved font is restored.
-
-     This number of lines still to be underlined is associated with the
-     current environment (*note Environments::).  The underline font
-     can be changed with the `uf' request.
-
-     The `ul' request does not underline spaces.
-
- -- Request: .cu [lines]
-     The `cu' request is similar to `ul' but underlines spaces as well
-     (if a TTY output device is used).
-
- -- Request: .uf font
-     Set the underline font (globally) used by `ul' and `cu'.  By
-     default, this is the font at position 2.  FONT can be either a
-     non-negative font position or the name of a font.
-
- -- Request: .bd font [offset]
- -- Request: .bd font1 font2 [offset]
- -- Register: \n[.b]
-     Artificially create a bold font by printing each glyph twice,
-     slightly offset.
-
-     Two syntax forms are available.
-
-        * Imitate a bold font unconditionally.  The first argument
-          specifies the font to embolden, and the second is the number
-          of basic units, minus one, by which the two glyphs are
-          offset.  If the second argument is missing, emboldening is
-          turned off.
-
-          FONT can be either a non-negative font position or the name
-          of a font.
-
-          OFFSET is available in the `.b' read-only register if a
-          special font is active; in the `bd' request, its default unit
-          is `u'.
-
-        * Imitate a bold form conditionally.  Embolden FONT1 by OFFSET
-          only if font FONT2 is the current font.  This command can be
-          issued repeatedly to set up different emboldening values for
-          different current fonts.  If the second argument is missing,
-          emboldening is turned off for this particular current font.
-
-          This affects special fonts only (either set up with the
-          `special' command in font files or with the `fspecial'
-          request).
-
- -- Request: .cs font [width [em-size]]
-     Switch to and from "constant glyph space mode".  If activated, the
-     width of every glyph is WIDTH/36 ems.  The em size is given
-     absolutely by EM-SIZE; if this argument is missing, the em value
-     is taken from the current font size (as set with the `ps' request)
-     when the font is effectively in use.  Without second and third
-     argument, constant glyph space mode is deactivated.
-
-     Default scaling indicator for EM-SIZE is `z'; WIDTH is an integer.

-5.17.7 Ligatures and Kerning
-----------------------------
-
-Ligatures are groups of characters that are run together, i.e, producing
-a single glyph.  For example, the letters `f' and `i' can form a
-ligature `fi' as in the word `file'.  This produces a cleaner look
-(albeit subtle) to the printed output.  Usually, ligatures are not
-available in fonts for TTY output devices.
-
-   Most POSTSCRIPT fonts support the fi and fl ligatures.  The C/A/T
-typesetter that was the target of AT&T `troff' also supported `ff',
-`ffi', and `ffl' ligatures.  Advanced typesetters or `expert' fonts may
-include ligatures for `ft' and `ct', although GNU `troff' does not
-support these (yet).
-
-   Only the current font is checked for ligatures and kerns; neither
-special fonts nor entities defined with the `char' request (and its
-siblings) are taken into account.
-
- -- Request: .lg [flag]
- -- Register: \n[.lg]
-     Switch the ligature mechanism on or off; if the parameter is
-     non-zero or missing, ligatures are enabled, otherwise disabled.
-     Default is on.  The current ligature mode can be found in the
-     read-only number register `.lg' (set to 1 or 2 if ligatures are
-     enabled, 0 otherwise).
-
-     Setting the ligature mode to 2 enables the two-character ligatures
-     (fi, fl, and ff) and disables the three-character ligatures (ffi
-     and ffl).
-
-   "Pairwise kerning" is another subtle typesetting mechanism that
-modifies the distance between a glyph pair to improve readability.  In
-most cases (but not always) the distance is decreased.  Typewriter-like
-fonts and fonts for terminals where all glyphs have the same width
-don't use kerning.
-
- -- Request: .kern [flag]
- -- Register: \n[.kern]
-     Switch kerning on or off.  If the parameter is non-zero or missing,
-     enable pairwise kerning, otherwise disable it.  The read-only
-     number register `.kern' is set to 1 if pairwise kerning is enabled,
-     0 otherwise.
-
-     If the font description file contains pairwise kerning information,
-     glyphs from that font are kerned.  Kerning between two glyphs can
-     be inhibited by placing `\&' between them: `V\&A'.
-
-     *Note Font File Format::.
-
-   "Track kerning" expands or reduces the space between glyphs.  This
-can be handy, for example, if you need to squeeze a long word onto a
-single line or spread some text to fill a narrow column.  It must be
-used with great care since it is usually considered bad typography if
-the reader notices the effect.
-
- -- Request: .tkf f s1 n1 s2 n2
-     Enable track kerning for font F.  If the current font is F the
-     width of every glyph is increased by an amount between N1 and N2
-     (N1, N2 can be negative); if the current point size is less than
-     or equal to S1 the width is increased by N1; if it is greater than
-     or equal to S2 the width is increased by N2; if the point size is
-     greater than or equal to S1 and less than or equal to S2 the
-     increase in width is a linear function of the point size.
-
-     The default scaling indicator is `z' for S1 and S2, `p' for N1 and
-     N2.
-
-     Note that the track kerning amount is added even to the rightmost
-     glyph in a line; for large values it is thus recommended to
-     increase the line length by the same amount to compensate it.
-
-   Sometimes, when typesetting letters of different fonts, more or less
-space at such boundaries are needed.  There are two escapes to help
-with this.
-
- -- Escape: \/
-     Increase the width of the preceding glyph so that the spacing
-     between that glyph and the following glyph is correct if the
-     following glyph is a roman glyph.  For example, if an italic `f'
-     is immediately followed by a roman right parenthesis, then in many
-     fonts the top right portion of the `f' overlaps the top left of
-     the right parenthesis.  Use this escape sequence whenever an
-     italic glyph is immediately followed by a roman glyph without any
-     intervening space.  This small amount of space is also called
-     "italic correction".
-
-
- -- Escape: \,
-     Modify the spacing of the following glyph so that the spacing
-     between that glyph and the preceding glyph is correct if the
-     preceding glyph is a roman glyph.  Use this escape sequence
-     whenever a roman glyph is immediately followed by an italic glyph
-     without any intervening space.  In analogy to above, this space
-     could be called "left italic correction", but this term isn't used
-     widely.
-
-
- -- Escape: \&
-     Insert a zero-width character, which is invisible.  Its intended
-     use is to stop interaction of a character with its surrounding.
-
-        * It prevents the insertion of extra space after an
-          end-of-sentence character.
-
-
-               Test.
-               Test.

-               Test.\&
-               Test.
-                   => Test. Test.
-
-        * It prevents interpretation of a control character at the
-          beginning of an input line.

-
-        * It is needed to map an arbitrary character to nothing in the
-          `tr' request (*note Character Translations::).
-
- -- Escape: \)
-     This escape is similar to `\&' except that it behaves like a
-     character declared with the `cflags' request to be transparent for
-     the purposes of an end-of-sentence character.
-
-     Its main usage is in macro definitions to protect against arguments
-     starting with a control character.

-5.18 Sizes
-==========
-
-`gtroff' uses two dimensions with each line of text, type size and
-vertical spacing.  The "type size" is approximately the height of the
-tallest glyph.(1) (*note Sizes-Footnote-1::)  "Vertical spacing" is the
-amount of space `gtroff' allows for a line of text; normally, this is
-about 20% larger than the current type size.  Ratios smaller than this
-can result in hard-to-read text; larger than this, it spreads the text
-out more vertically (useful for term papers).  By default, `gtroff'
-uses 10 point type on 12 point spacing.
-
-   The difference between type size and vertical spacing is known, by
-typesetters, as "leading" (this is pronounced `ledding').

-   (1) This is usually the parenthesis.  Note that in most cases the
-real dimensions of the glyphs in a font are _not_ related to its type
-size!  For example, the standard POSTSCRIPT font families `Times
-Roman', `Helvetica', and `Courier' can't be used together at 10pt; to
-get acceptable output, the size of `Helvetica' has to be reduced by one
-point, and the size of `Courier' must be increased by one point.

---------------------------
-
- -- Request: .ps [size]
- -- Request: .ps +size
- -- Request: .ps -size
- -- Escape: \ssize
- -- Register: \n[.s]
-     Use the `ps' request or the `\s' escape to change (increase,
-     decrease) the type size (in points).  Specify SIZE as either an
-     absolute point size, or as a relative change from the current size.
-     The size 0, or no argument, goes back to the previous size.
-
-     Default scaling indicator of `size' is `z'.  If `size' is zero or
-     negative, it is set to 1u.
-
-     The read-only number register `.s' returns the point size in
-     points as a decimal fraction.  This is a string.  To get the point
-     size in scaled points, use the `.ps' register instead.
-
-     `.s' is associated with the current environment (*note
-     Environments::).
-

-          wink, wink, \s+2nudge, nudge,\s+8 say no more!
-          .ps 10
-
-     The `\s' escape may be called in a variety of ways.  Much like
-     other escapes there must be a way to determine where the argument
-     ends and the text begins.  Any of the following forms are valid:
-
-    `\sN'
-          Set the point size to N points.  N must be either 0 or in the
-          range 4 to 39.
-
-    `\s+N'
-    `\s-N'
-          Increase or decrease the point size by N points.  N must be
-          exactly one digit.
-
-    `\s(NN'
-          Set the point size to NN points.  NN must be exactly two
-          digits.
-
-    `\s+(NN'
-    `\s-(NN'
-    `\s(+NN'
-    `\s(-NN'
-          Increase or decrease the point size by NN points.  NN must be
-          exactly two digits.
-
-     Note that `\s' doesn't produce an input token in `gtroff'.  As a
-     consequence, it can be used in requests like `mc' (which expects a
-     single character as an argument) to change the font on the fly:
-
-
-          .mc \s[20]x\s[0]
-
-     *Note Fractional Type Sizes::, for yet another syntactical form of
-     using the `\s' escape.
-
- -- Request: .sizes s1 s2 ... sn [0]
-     Some devices may only have certain permissible sizes, in which case
-     `gtroff' rounds to the nearest permissible size.  The `DESC' file
-     specifies which sizes are permissible for the device.
-
-     Use the `sizes' request to change the permissible sizes for the
-     current output device.  Arguments are in scaled points; the
-     `sizescale' line in the `DESC' file for the output device provides
-     the scaling factor.  For example, if the scaling factor is 1000,
-     then the value 12000 is 12 points.
-
-     Each argument can be a single point size (such as `12000'), or a
-     range of sizes (such as `4000-72000').  You can optionally end the
-     list with a zero.
-
- -- Request: .vs [space]
- -- Request: .vs +space
- -- Request: .vs -space
- -- Register: \n[.v]
-     Change (increase, decrease) the vertical spacing by SPACE.  The
-     default scaling indicator is `p'.
-
-     If `vs' is called without an argument, the vertical spacing is
-     reset to the previous value before the last call to `vs'.
-
-     `gtroff' creates a warning of type `range' if SPACE is negative;
-     the vertical spacing is then set to smallest positive value, the
-     vertical resolution (as given in the `.V' register).
-
-     Note that `.vs 0' isn't saved in a diversion since it doesn't
-     result in a vertical motion.  You explicitly have to repeat this
-     command before inserting the diversion.
-
-     The read-only number register `.v' contains the current vertical
-     spacing; it is associated with the current environment (*note
-     Environments::).
-
-   The effective vertical line spacing consists of four components.
-Breaking a line causes the following actions (in the given order).
-
-   * Move the current point vertically by the "extra pre-vertical line
-     space".  This is the minimum value of all `\x' escapes with a
-     negative argument in the current output line.
-
-   * Move the current point vertically by the vertical line spacing as
-     set with the `vs' request.
-
-   * Output the current line.
-
-   * Move the current point vertically by the "extra post-vertical line
-     space".  This is the maximum value of all `\x' escapes with a
-     positive argument in the line which has just been output.
-
-   * Move the current point vertically by the "post-vertical line
-     spacing" as set with the `pvs' request.
-
-   It is usually better to use `vs' or `pvs' instead of `ls' to produce
-double-spaced documents: `vs' and `pvs' have a finer granularity for
-the inserted vertical space compared to `ls'; furthermore, certain
-preprocessors assume single-spacing.
-
-   *Note Manipulating Spacing::, for more details on the `\x' escape
-and the `ls' request.
-
- -- Request: .pvs [space]
- -- Request: .pvs +space
- -- Request: .pvs -space
- -- Register: \n[.pvs]
-     Change (increase, decrease) the post-vertical spacing by SPACE.
-     The default scaling indicator is `p'.
-
-     If `pvs' is called without an argument, the post-vertical spacing
-     is reset to the previous value before the last call to `pvs'.
-
-     `gtroff' creates a warning of type `range' if SPACE is zero or
-     negative; the vertical spacing is then set to zero.
-
-     The read-only number register `.pvs' contains the current
-     post-vertical spacing; it is associated with the current
-     environment (*note Environments::).

-5.18.2 Fractional Type Sizes
-----------------------------
-
-A "scaled point" is equal to 1/SIZESCALE points, where SIZESCALE is
-specified in the `DESC' file (1 by default).  There is a new scale
-indicator `z' which has the effect of multiplying by SIZESCALE.
-Requests and escape sequences in `gtroff' interpret arguments that
-represent a point size as being in units of scaled points, but they
-evaluate each such argument using a default scale indicator of `z'.
-Arguments treated in this way are the argument to the `ps' request, the
-third argument to the `cs' request, the second and fourth arguments to
-the `tkf' request, the argument to the `\H' escape sequence, and those
-variants of the `\s' escape sequence that take a numeric expression as
-their argument (see below).
-
-   For example, suppose SIZESCALE is 1000; then a scaled point is
-equivalent to a millipoint; the request `.ps 10.25' is equivalent to
-`.ps 10.25z' and thus sets the point size to 10250 scaled points, which
-is equal to 10.25 points.
-
-   `gtroff' disallows the use of the `z' scale indicator in instances
-where it would make no sense, such as a numeric expression whose
-default scale indicator was neither `u' nor `z'.  Similarly it would
-make no sense to use a scaling indicator other than `z' or `u' in a
-numeric expression whose default scale indicator was `z', and so
-`gtroff' disallows this as well.
-
-   There is also new scale indicator `s' which multiplies by the number
-of units in a scaled point.  So, for example, `\n[.ps]s' is equal to
-`1m'.  Be sure not to confuse the `s' and `z' scale indicators.
-
- -- Register: \n[.ps]
-     A read-only number register returning the point size in scaled
-     points.
-
-     `.ps' is associated with the current environment (*note
-     Environments::).
-
- -- Register: \n[.psr]
- -- Register: \n[.sr]
-     The last-requested point size in scaled points is contained in the
-     `.psr' read-only number register.  The last requested point size
-     in points as a decimal fraction can be found in `.sr'.  This is a
-     string-valued read-only number register.
-
-     Note that the requested point sizes are device-independent, whereas
-     the values returned by the `.ps' and `.s' registers are not.  For
-     example, if a point size of 11pt is requested, and a `sizes'
-     request (or a `sizescale' line in a `DESC' file) specifies 10.95pt
-     instead, this value is actually used.
-
-     Both registers are associated with the current environment (*note
-     Environments::).
-
-   The `\s' escape has the following syntax for working with fractional
-type sizes:
-
-`\s[N]'
-`\s'N''
-     Set the point size to N scaled points; N is a numeric expression
-     with a default scale indicator of `z'.
-
-`\s[+N]'
-`\s[-N]'
-`\s+[N]'
-`\s-[N]'
-`\s'+N''
-`\s'-N''
-`\s+'N''
-`\s-'N''
-     Increase or or decrease the point size by N scaled points; N is a
-     numeric expression with a default scale indicator of `z'.

-   *Note Font Files::.

-5.19 Strings
-============
-
-`gtroff' has string variables, which are entirely for user convenience
-(i.e. there are no built-in strings exept `.T', but even this is a
-read-write string variable).
-
- -- Request: .ds name [string]
- -- Request: .ds1 name [string]
- -- Escape: \*n
- -- Escape: \*(nm
- -- Escape: \*[name arg1 arg2 ...]
-     Define and access a string variable NAME (one-character name N,
-     two-character name NM).  If NAME already exists, `ds' overwrites
-     the previous definition.  Only the syntax form using brackets can
-     take arguments which are handled identically to macro arguments;
-     the single exception is that a closing bracket as an argument must
-     be enclosed in double quotes.  *Note Request and Macro
-     Arguments::, and *Note Parameters::.
-
-     Example:
-
-
-          .ds foo a \\$1 test
-          .
-          This is \*[foo nice].
-              => This is a nice test.
-
-     The `\*' escape "interpolates" (expands in-place) a
-     previously-defined string variable.  To be more precise, the stored
-     string is pushed onto the input stack which is then parsed by
-     `gtroff'.  Similar to number registers, it is possible to nest
-     strings, i.e. string variables can be called within string
-     variables.
-
-     If the string named by the `\*' escape does not exist, it is
-     defined as empty, and a warning of type `mac' is emitted (see
-     *Note Debugging::, for more details).
-
-     *Caution:* Unlike other requests, the second argument to the `ds'
-     request takes up the entire line including trailing spaces.  This
-     means that comments on a line with such a request can introduce
-     unwanted space into a string.
-
-
-          .ds UX \s-1UNIX\s0\u\s-3tm\s0\d \" UNIX trademark
-
-     Instead the comment should be put on another line or have the
-     comment escape adjacent with the end of the string.
-
-
-          .ds UX \s-1UNIX\s0\u\s-3tm\s0\d\"  UNIX trademark
-
-     To produce leading space the string can be started with a double
-     quote.  No trailing quote is needed; in fact, any trailing quote is
-     included in your string.
-
-
-          .ds sign "           Yours in a white wine sauce,
-
-     Strings are not limited to a single line of text.  A string can
-     span several lines by escaping the newlines with a backslash.  The
-     resulting string is stored _without_ the newlines.
-
-
-          .ds foo lots and lots \
-          of text are on these \
-          next several lines
-
-     It is not possible to have real newlines in a string.  To put a
-     single double quote character into a string, use two consecutive
-     double quote characters.
-
-     The `ds1' request turns off compatibility mode while interpreting
-     a string.  To be more precise, a "compatibility save" input token
-     is inserted at the beginning of  the string, and a "compatibility
-     restore" input token at the end.
-
-
-          .nr xxx 12345
-          .ds aa The value of xxx is \\n[xxx].
-          .ds1 bb The value of xxx ix \\n[xxx].
-          .
-          .cp 1
-          .
-          \*(aa
-              => warning: number register `[' not defined
-              => The value of xxx is 0xxx].
-          \*(bb
-              => The value of xxx ix 12345.
-
-     Strings, macros, and diversions (and boxes) share the same name
-     space.  Internally, even the same mechanism is used to store them.
-     This has some interesting consequences.  For example, it is
-     possible to call a macro with string syntax and vice versa.
-
-
-          .de xxx
-          a funny test.
-          ..
-          This is \*[xxx]
-              => This is a funny test.
-
-          .ds yyy a funny test
-          This is
-          .yyy
-              => This is a funny test.
-
-     Diversions and boxes can be also called with string syntax.
-
-     Another consequence is that you can copy one-line diversions or
-     boxes to a string.
-
-
-          .di xxx
-          a \fItest\fR
-          .br
-          .di
-          .ds yyy This is \*[xxx]\c
-          \*[yyy].
-              => This is a test.
-
-     As the previous example shows, it is possible to store formatted
-     output in strings.  The `\c' escape prevents the insertion of an
-     additional blank line in the output.
-
-     Copying diversions longer than a single output line produces
-     unexpected results.
-
-
-          .di xxx
-          a funny
-          .br
-          test
-          .br
-          .di
-          .ds yyy This is \*[xxx]\c
-          \*[yyy].
-              => test This is a funny.
-
-     Usually, it is not predictable whether a diversion contains one or
-     more output lines, so this mechanism should be avoided.  With UNIX
-     `troff', this was the only solution to strip off a final newline
-     from a diversion.  Another disadvantage is that the spaces in the
-     copied string are already formatted, making them unstretchable.
-     This can cause ugly results.
-
-     A clean solution to this problem is available in GNU `troff',
-     using the requests `chop' to remove the final newline of a
-     diversion, and `unformat' to make the horizontal spaces
-     stretchable again.
-
-
-          .box xxx
-          a funny
-          .br
-          test
-          .br
-          .box
-          .chop xxx
-          .unformat xxx
-          This is \*[xxx].
-              => This is a funny test.
-

-
- -- Request: .as name [string]
- -- Request: .as1 name [string]

-     exist yet, it is created.

-     The `as1' request is similar to `as', but compatibility mode is
-     switched off while the appended string is interpreted.  To be more
-     precise, a "compatibility save" input token is inserted at the
-     beginning of the appended string, and a "compatibility restore"
-     input token at the end.
-
-   Rudimentary string manipulation routines are given with the next two
-requests.
-
- -- Request: .substring str n1 [n2]
-     Replace the string named STR with the substring defined by the
-     indices N1 and N2.  The first character in the string has index 0.
-     If N2 is omitted, it is taken to be equal to the string's length.
-     If the index value N1 or N2 is negative, it is counted from the
-     end of the string, going backwards: The last character has
-     index -1, the character before the last character has index -2,
-     etc.
-
-
-          .ds xxx abcdefgh
-          .substring xxx 1 -4
-          \*[xxx]
-              => bcde
-
-
- -- Request: .length reg str
-     Compute the number of characters of STR and return it in the
-     number register REG.  If REG doesn't exist, it is created.  `str'
-     is read in copy mode.
-
-
-          .ds xxx abcd\h'3i'efgh
-          .length yyy \*[xxx]
-          \n[yyy]
-              => 14
-
-
- -- Request: .rn xx yy
-     Rename the request, macro, diversion, or string XX to YY.
-
- -- Request: .rm xx
-     Remove the request, macro, diversion, or string XX.  `gtroff'
-     treats subsequent invocations as if the object had never been
-     defined.
-
- -- Request: .als new old
-     Create an alias named NEW for the request, string, macro, or
-     diversion object named OLD.  The new name and the old name are
-     exactly equivalent (it is similar to a hard rather than a soft
-     link). If OLD is undefined, `gtroff' generates a warning of type
-     `mac' and ignores the request.
-
- -- Request: .chop xx
-     Remove (chop) the last character from the macro, string, or
-     diversion named XX.  This is useful for removing the newline from
-     the end of diversions that are to be interpolated as strings.
-     This command can be used repeatedly; see *Note Gtroff Internals::,
-     for details on nodes inserted additionally by `gtroff'.

-
-5.20.1 Operators in Conditionals
---------------------------------
-
-In `if' and `while' requests, there are several more operators
-available:
-
-`e'
-`o'
-     True if the current page is even or odd numbered (respectively).
-
-`n'
-     True if the document is being processed in nroff mode (i.e., the
-     `.nroff' command has been issued).
-
-`t'
-     True if the document is being processed in troff mode (i.e., the
-     `.troff' command has been issued).
-
-`v'
-     Always false.  This condition is for compatibility with other
-     `troff' versions only (identifying a `-Tversatec' device).
-
-`'XXX'YYY''
-     True if the string XXX is equal to the string YYY.  Other
-     characters can be used in place of the single quotes; the same set
-     of delimiters as for the `\D' escape is used (*note Escapes::).
-     `gtroff' formats the strings before being compared:
-
-
-          .ie "|"\fR|\fP" \
-          true
-          .el \
-          false
-              => true
-
-     The resulting motions, glyph sizes, and fonts have to match,(1)
-     (*note Operators in Conditionals-Footnote-1::) and not the
-     individual motion, size, and font requests.  In the previous
-     example, `|' and `\fR|\fP' both result in a roman `|' glyph with
-     the same point size and at the same location on the page, so the
-     strings are equal.  If `.ft I' had been added before the `.ie',
-     the result would be "false" because (the first) `|' produces an
-     italic `|' rather than a roman one.
-
-`r XXX'
-     True if there is a number register named XXX.
-
-`d XXX'
-     True if there is a string, macro, diversion, or request named XXX.
-
-`m XXX'
-     True if there is a color named XXX.
-
-`c G'
-     True if there is a glyph G available(2) (*note Operators in
-     Conditionals-Footnote-2::); G is either an ASCII character or a
-     special character (`\(GG' or `\[GGG]'); the condition is also true
-     if G has been defined by the `char' request.
-
-`F FONT'
-     True if a font named FONT exists.  FONT is handled as if it was
-     opened with the `ft' request (this is, font translation and styles
-     are applied), without actually mounting it.
-
-     This test doesn't load the complete font but only its header to
-     verify its validity.
-
-`S STYLE'
-     True if style STYLE has been registered.  Font translation is
-     applied.
-
-   Note that these operators can't be combined with other operators like
-`:' or `&'; only a leading `!' (without whitespace between the
-exclamation mark and the operator) can be used to negate the result.
-
-
-     .nr xxx 1
-     .ie !r xxx \
-     true
-     .el \
-     false
-         => false
-
-   A whitespace after `!' always evaluates to zero (this bizarre
-behaviour is due to compatibility with UNIX `troff').
-
-
-     .nr xxx 1
-     .ie ! r xxx \
-     true
-     .el \
-     false
-         => r xxx true
-
-   It is possible to omit the whitespace before the argument to the
-`r', `d', and `c' operators.

-5.20.2 if-else
---------------
-
-`gtroff' has if-then-else constructs like other languages, although the
-formatting can be painful.
-
- -- Request: .if expr anything
-     Evaluate the expression EXPR, and executes ANYTHING (the remainder
-     of the line) if EXPR evaluates to a value greater than zero
-     (true).  ANYTHING is interpreted as though it was on a line by
-     itself (except that leading spaces are swallowed).  *Note
-     Expressions::, for more info.
-
-
-          .nr xxx 1
-          .nr yyy 2
-          .if ((\n[xxx] == 1) & (\n[yyy] == 2)) true
-              => true
-
-
- -- Request: .nop anything
-     Executes ANYTHING.  This is similar to `.if 1'.
-
- -- Request: .ie expr anything
- -- Request: .el anything
-     Use the `ie' and `el' requests to write an if-then-else.  The
-     first request is the `if' part and the latter is the `else' part.
-
-
-          .ie n .ls 2 \" double-spacing in nroff
-          .el   .ls 1 \" single-spacing in troff
-
-
- -- Escape: \{
- -- Escape: \}
-     In many cases, an if (or if-else) construct needs to execute more
-     than one request.  This can be done using the `\{' and `\}'
-     escapes.  The following example shows the possible ways to use
-     these escapes (note the position of the opening and closing
-     braces).
-
-
-          .ie t \{\
-          .    ds lq ``
-          .    ds rq ''
-          .\}
-          .el \
-          .\{\
-          .    ds lq "
-          .    ds rq "\}
-
-
-   *Note Expressions::.
-
-
-File: groff,  Node: while,  Prev: if-else,  Up: Conditionals and Loops
-
-5.20.3 while
-------------
-
-`gtroff' provides a looping construct using the `while' request, which
-is used much like the `if' (and related) requests.
-
- -- Request: .while expr anything
-     Evaluate the expression EXPR, and repeatedly execute ANYTHING (the
-     remainder of the line) until EXPR evaluates to 0.
-
-
-          .nr a 0 1
-          .while (\na < 9) \{\
-          \n+a,
-          .\}
-          \n+a
-              => 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
-
-     Some remarks.
-
-        * The body of a `while' request is treated like the body of a
-          `de' request: `gtroff' temporarily stores it in a macro which
-          is deleted after the loop has been exited.  It can
-          considerably slow down a macro if the body of the `while'
-          request (within the macro) is large.  Each time the macro is
-          executed, the `while' body is parsed and stored again as a
-          temporary macro.
-
-
-               .de xxx
-               .  nr num 10
-               .  while (\\n[num] > 0) \{\
-               .    \" many lines of code
-               .    nr num -1
-               .  \}
-               ..
-
-          The traditional and ofter better solution (UNIX `troff'
-          doesn't have the `while' request) is to use a recursive macro
-          instead which is parsed only once during its definition.
-
-
-               .de yyy
-               .  if (\\n[num] > 0) \{\
-               .    \" many lines of code
-               .    nr num -1
-               .    yyy
-               .  \}
-               ..
-               .
-               .de xxx
-               .  nr num 10
-               .  yyy
-               ..
-
-          Note that the number of available recursion levels is set
-          to 1000 (this is a compile-time constant value of `gtroff').
-
-        * The closing brace of a `while' body must end a line.
-
-
-               .if 1 \{\
-               .  nr a 0 1
-               .  while (\n[a] < 10) \{\
-               .    nop \n+[a]
-               .\}\}
-                   => unbalanced \{ \}
-
-
- -- Request: .break
-     Break out of a `while' loop.  Be sure not to confuse this with the
-     `br' request (causing a line break).
-
- -- Request: .continue
-     Finish the current iteration of a `while' loop, immediately
-     restarting the next iteration.

-5.21 Writing Macros
-===================
-
-A "macro" is a collection of text and embedded commands which can be
-invoked multiple times.  Use macros to define common operations.
-
- -- Request: .de name [end]
- -- Request: .de1 name [end]
- -- Request: .dei name [end]
- -- Request: .dei1 name [end]
-     Define a new macro named NAME.  `gtroff' copies subsequent lines
-     (starting with the next one) into an internal buffer until it
-     encounters the line `..' (two dots).  The optional second argument
-     to `de' changes this to a macro to `.END'.
-
-     There can be whitespace after the first dot in the line containing
-     the ending token (either `.' or macro `END').
-
-     Here a small example macro called `P' which causes a break and
-     inserts some vertical space.  It could be used to separate
-     paragraphs.
-
-
-          .de P
-          .  br
-          .  sp .8v
-          ..
-
-     The following example defines a macro within another.  Remember
-     that expansion must be protected twice; once for reading the macro
-     and once for executing.
-
-
-          \# a dummy macro to avoid a warning
-          .de end
-          ..
-          .
-          .de foo
-          .  de bar end
-          .    nop \f[B]Hallo \\\\$1!\f[]
-          .  end
-          ..
-          .
-          .foo
-          .bar Joe
-              => Hallo Joe!
-
-     Since `\f' has no expansion, it isn't necessary to protect its
-     backslash.  Had we defined another macro within `bar' which takes
-     a parameter, eight backslashes would be necessary before `$1'.
-
-     The `de1' request turns off compatibility mode while executing the
-     macro.  On entry, the current compatibility mode is saved and
-     restored at exit.
-
-
-          .nr xxx 12345
-          .
-          .de aa
-          The value of xxx is \\n[xxx].
-          ..
-          .de1 bb
-          The value of xxx ix \\n[xxx].
-          ..
-          .
-          .cp 1
-          .
-          .aa
-              => warning: number register `[' not defined
-              => The value of xxx is 0xxx].
-          .bb
-              => The value of xxx ix 12345.
-
-     The `dei' request defines a macro indirectly.  That is, it expands
-     strings whose names are NAME or END before performing the append.
-
-     This:
-
-
-          .ds xx aa
-          .ds yy bb
-          .dei xx yy
-
-     is equivalent to:
-
-
-          .de aa bb
-
-     The `dei1' request is similar to `dei' but with compatibility mode
-     switched off during execution of the defined macro.
-
-     If compatibility mode is on, `de' (and `dei') behave similar to
-     `de1' (and `dei1'): A `compatibility save' token is inserted at
-     the beginning, and a `compatibility restore' token at the end, with
-     compatibility mode switched on during execution.  *Note Gtroff
-     Internals::, for more information on switching compatibility mode
-     on and off in a single document.
-
-     Using `trace.tmac', you can trace calls to `de' and `de1'.
-
-     Note that macro identifiers are shared with identifiers for
-     strings and diversions.
-
- -- Request: .am name [end]
- -- Request: .am1 name [end]
- -- Request: .ami name [end]
- -- Request: .ami1 name [end]
-     Works similarly to `de' except it appends onto the macro named
-     NAME.  So, to make the previously defined `P' macro actually do
-     indented instead of block paragraphs, add the necessary code to the
-     existing macro like this:
-
-
-          .am P
-          .ti +5n
-          ..
-
-     The `am1' request turns off compatibility mode while executing the
-     appended macro piece.  To be more precise, a "compatibility save"
-     input token is inserted at the beginning of the appended code, and
-     a "compatibility restore" input token at the end.
-
-     The `ami' request appends indirectly, meaning that `gtroff'
-     expands strings whose names are NAME or END before performing the
-     append.
-
-     The `ami1' request is similar to `ami' but compatibility mode is
-     switched off during execution of the defined macro.
-
-     Using `trace.tmac', you can trace calls to `am' and `am1'.
-
-   *Note Strings::, for the `als' request to rename a macro.
-
-   The `de', `am', `di', `da', `ds', and `as' requests (together with
-its variants) only create a new object if the name of the macro,
-diversion or string diversion is currently undefined or if it is
-defined to be a request; normally they modify the value of an existing
-object.
-
- -- Request: .return [anything]
-     Exit a macro, immediately returning to the caller.
-
-     If called with an argument, exit twice, namely the current macro
-     and the macro one level higher.  This is used to define a wrapper
-     macro for `return' in `trace.tmac'.

-
-5.21.1 Copy-in Mode
--------------------
-
-When `gtroff' reads in the text for a macro, string, or diversion, it
-copies the text (including request lines, but excluding escapes) into
-an internal buffer.  Escapes are converted into an internal form,
-except for `\n', `\$', `\*', `\\' and `\<RET>' which are evaluated and
-inserted into the text where the escape was located.  This is known as
-"copy-in" mode or "copy" mode.
-
-   What this means is that you can specify when these escapes are to be
-evaluated (either at copy-in time or at the time of use) by insulating
-the escapes with an extra backslash.  Compare this to the `\def' and
-`\edef' commands in TeX.
-
-   The following example prints the numbers 20 and 10:
-
-
-     .nr x 20
-     .de y
-     .nr x 10
-     \&\nx

-
-5.21.2 Parameters
------------------
-
-The arguments to a macro or string can be examined using a variety of
-escapes.
-
- -- Register: \n[.$]
-     The number of arguments passed to a macro or string.  This is a
-     read-only number register.
-
-     Note that the `shift' request can change its value.
-
-   Any individual argument can be retrieved with one of the following
-escapes:
-
- -- Escape: \$n
- -- Escape: \$(nn
- -- Escape: \$[nnn]
-     Retrieve the Nth, NNth or NNNth argument.  As usual, the first
-     form only accepts a single number (larger than zero), the second a
-     two-digit number (larger or equal to 10), and the third any
-     positive integer value (larger than zero).  Macros and strings can
-     have an unlimited number of arguments.  Note that due to copy-in
-     mode, use two backslashes on these in actual use to prevent
-     interpolation until the macro is actually invoked.
-
- -- Request: .shift [n]
-     Shift the arguments 1 position, or as many positions as specified
-     by its argument.  After executing this request, argument I becomes
-     argument I-N; arguments 1 to N are no longer available.  Shifting
-     by negative amounts is currently undefined.
-
-     The register `.$' is adjusted accordingly.
-
- -- Escape: \$*
- -- Escape: \$@
-     In some cases it is convenient to use all of the arguments at once
-     (for example, to pass the arguments along to another macro).  The
-     `\$*' escape concatenates all the arguments separated by spaces.  A
-     similar escape is `\$@', which concatenates all the arguments with
-     each surrounded by double quotes, and separated by spaces.  If not
-     in compatibility mode, the input level of double quotes is
-     preserved (see *Note Request and Macro Arguments::).
-
- -- Escape: \$0
-     The name used to invoke the current macro.  The `als' request can
-     make a macro have more than one name.
-
-
-          .de generic-macro
-          .  ...
-          .  if \\n[error] \{\
-          .    tm \\$0: Houston, we have a problem.
-          .    return
-          .  \}
-          ..

-5.22 Page Motions
-=================
-
-*Note Manipulating Spacing::, for a discussion of the main request for
-vertical motion, `sp'.
-
- -- Request: .mk [reg]
- -- Request: .rt [dist]
-     The request `mk' can be used to mark a location on a page, for
-     movement to later.  This request takes a register name as an
-     argument in which to store the current page location.  With no
-     argument it stores the location in an internal register.  The
-     results of this can be used later by the `rt' or the `sp' request
-     (or the `\v' escape).
-
-     The `rt' request returns _upwards_ to the location marked with the
-     last `mk' request.  If used with an argument, return to a position
-     which distance from the top of the page is DIST (no previous call
-     to `mk' is necessary in this case).  Default scaling indicator is
-     `v'.

-
-
-   The following escapes give fine control of movements about the page.
-
- -- Escape: \v'e'
-     Move vertically, usually from the current location on the page (if
-     no absolute position operator `|' is used).  The argument E
-     specifies the distance to move; positive is downwards and negative
-     upwards.  The default scaling indicator for this escape is `v'.
-     Beware, however, that `gtroff' continues text processing at the
-     point where the motion ends, so you should always balance motions
-     to avoid interference with text processing.
-
-     `\v' doesn't trigger a trap.  This can be quite useful; for
-     example, consider a page bottom trap macro which prints a marker
-     in the margin to indicate continuation of a footnote or something
-     similar.
-
-   There are some special-case escapes for vertical motion.
-
- -- Escape: \r
-     Move upwards 1v.
-
- -- Escape: \u
-     Move upwards .5v.
-
- -- Escape: \d
-     Move down .5v.
-
- -- Escape: \h'e'
-     Move horizontally, usually from the current location (if no
-     absolute position operator `|' is used).  The expression E
-     indicates how far to move: positive is rightwards and negative
-     leftwards.  The default scaling indicator for this escape is `m'.
-
-     This horizontal space is not discarded at the end of a line.  To
-     insert discardable space of a certain length use the `ss' request.
-
-   There are a number of special-case escapes for horizontal motion.
-
- -- Escape: \<SP>
-     An unbreakable and unpaddable (i.e. not expanded during filling)
-     space.  (Note: This is a backslash followed by a space.)
-
- -- Escape: \~
-     An unbreakable space that stretches like a normal inter-word space
-     when a line is adjusted.
-
- -- Escape: \|
-     A 1/6th em space.  Ignored for TTY output devices (rounded to
-     zero).
-
- -- Escape: \^
-     A 1/12th em space.  Ignored for TTY output devices (rounded to
-     zero).
-
- -- Escape: \0
-     A space the size of a digit.
-
-   The following string sets the TeX logo:
-
-
-     .ds TeX T\h'-.1667m'\v'.224m'E\v'-.224m'\h'-.125m'X
-
- -- Escape: \w'text'
- -- Register: \n[st]
- -- Register: \n[sb]
- -- Register: \n[rst]
- -- Register: \n[rsb]
- -- Register: \n[ct]
- -- Register: \n[ssc]
- -- Register: \n[skw]
-     Return the width of the specified TEXT in basic units.  This
-     allows horizontal movement based on the width of some arbitrary
-     text (e.g. given as an argument to a macro).
-
-
-          The length of the string `abc' is \w'abc'u.
-              => The length of the string `abc' is 72u.
-
-     Font changes may occur in TEXT which don't affect current settings.
-
-     After use, `\w' sets several registers:
-
-    `st'
-    `sb'
-          The highest and lowest point of the baseline, respectively,
-          in TEXT.
-
-    `rst'
-    `rsb'
-          Like the `st' and `sb' registers, but takes account of the
-          heights and depths of glyphs.  With other words, this gives
-          the highest and lowest point of TEXT.  Values below the
-          baseline are negative.
-
-    `ct'
-          Defines the kinds of glyphs occurring in TEXT:
-
-         0
-               only short glyphs, no descenders or tall glyphs.
-
-         1
-               at least one descender.
-
-         2
-               at least one tall glyph.
-
-         3
-               at least one each of a descender and a tall glyph.
-
-    `ssc'
-          The amount of horizontal space (possibly negative) that
-          should be added to the last glyph before a subscript.
-
-    `skw'
-          How far to right of the center of the last glyph in the `\w'
-          argument, the center of an accent from a roman font should be
-          placed over that glyph.
-
- -- Escape: \kp
- -- Escape: \k(ps
- -- Escape: \k[position]
-     Store the current horizontal position in the _input_ line in
-     number register with name POSITION (one-character name P,
-     two-character name PS).  Use this, for example, to return to the
-     beginning of a string for highlighting or other decoration.
-
- -- Register: \n[hp]
-     The current horizontal position at the input line.
-
- -- Register: \n[.k]
-     A read-only number register containing the current horizontal
-     output position (relative to the current indentation).
-
- -- Escape: \o'abc'
-     Overstrike glyphs A, B, C, ...; the glyphs are centered, and the
-     resulting spacing is the largest width of the affected glyphs.
-
- -- Escape: \zg
-     Print glyph G with zero width, i.e., without spacing.  Use this to
-     overstrike glyphs left-aligned.
-
- -- Escape: \Z'anything'
-     Print ANYTHING, then restore the horizontal and vertical position.
-     The argument may not contain tabs or leaders.
-
-     The following is an example of a strike-through macro:
-
-
-          .de ST
-          .nr ww \w'\\$1'
-          \Z@\v'-.25m'\l'\\n[ww]u'@\\$1
-          ..
-          .
-          This is
-          .ST "a test"
-          an actual emergency!

-5.23 Drawing Requests
-=====================
-
-`gtroff' provides a number of ways to draw lines and other figures on
-the page.  Used in combination with the page motion commands (see *Note
-Page Motions::, for more info), a wide variety of figures can be drawn.
-However, for complex drawings these operations can be quite
-cumbersome, and it may be wise to use graphic preprocessors like `gpic'
-or `ggrn'.  *Note gpic::, and *Note ggrn::, for more information.
-
-   All drawing is done via escapes.
-
- -- Escape: \l'l'
- -- Escape: \l'lg'
-     Draw a line horizontally.  L is the length of the line to be
-     drawn.  If it is positive, start the line at the current location
-     and draw to the right; its end point is the new current location.
-     Negative values are handled differently: The line starts at the
-     current location and draws to the left, but the current location
-     doesn't move.
-
-     L can also be specified absolutely (i.e. with a leading `|') which
-     draws back to the beginning of the input line.  Default scaling
-     indicator is `m'.
-
-     The optional second parameter G is a glyph to draw the line with.
-     If this second argument is not specified, `gtroff' uses the
-     underscore glyph, `\[ru]'.
-
-     To separate the two arguments (to prevent `gtroff' from
-     interpreting a drawing glyph as a scaling indicator if the glyph is
-     represented by a single character) use `\&'.
-
-     Here a small useful example:
-
-
-          .de box
-          \[br]\\$*\[br]\l'|0\[rn]'\l'|0\[ul]'
-          ..
-
-     Note that this works by outputting a box rule (a vertical line),
-     then the text given as an argument and then another box rule.
-     Finally, the line drawing escapes both draw from the current
-     location to the beginning of the _input_ line - this works because
-     the line length is negative, not moving the current point.
-
- -- Escape: \L'l'
- -- Escape: \L'lg'
-     Draw vertical lines.  Its parameters are similar to the `\l'
-     escape, except that the default scaling indicator is `v'.  The
-     movement is downwards for positive values, and upwards for
-     negative values.  The default glyph is the box rule glyph,
-     `\[br]'.  As with the vertical motion escapes, text processing
-     blindly continues where the line ends.
-
-
-          This is a \L'3v'test.
-
-     Here the result, produced with `grotty'.
-
-
-          This is a
-                    |
-                    |
-                    |test.
-
-
- -- Escape: \D'command arg ...'
-     The `\D' escape provides a variety of drawing functions.  Note
-     that on character devices, only vertical and horizontal lines are
-     supported within `grotty'; other devices may only support a subset
-     of the available drawing functions.
-
-     The default scaling indicator for all subcommands of `\D' is `m'
-     for horizontal distances and `v' for vertical ones.  Exceptions
-     are `\D'f ...'' and `\D't ...'' which use `u' as the default, and
-     `\D'FX ...'' which arguments are treated similar to the `defcolor'
-     request.
-
-    `\D'l DX DY''
-          Draw a line from the current location to the relative point
-          specified by (DX,DY), where positive values mean down and
-          right, respectively.  The end point of the line is the new
-          current location.
-
-          The following example is a macro for creating a box around a
-          text string; for simplicity, the box margin is taken as a
-          fixed value, 0.2m.
-
-
-               .de BOX
-               .  nr @wd \w'\\$1'
-               \h'.2m'\
-               \h'-.2m'\v'(.2m - \\n[rsb]u)'\
-               \D'l 0 -(\\n[rst]u - \\n[rsb]u + .4m)'\
-               \D'l (\\n[@wd]u + .4m) 0'\
-               \D'l 0 (\\n[rst]u - \\n[rsb]u + .4m)'\
-               \D'l -(\\n[@wd]u + .4m) 0'\
-               \h'.2m'\v'-(.2m - \\n[rsb]u)'\
-               \\$1\
-               \h'.2m'
-               ..
-
-          First, the width of the string is stored in register `@wd'.
-          Then, four lines are drawn to form a box, properly offset by
-          the box margin.  The registers `rst' and `rsb' are set by the
-          `\w' escape, containing the largest height and depth of the
-          whole string.
-
-    `\D'c D''
-          Draw a circle with a diameter of D with the leftmost point at
-          the current position.  After drawing, the current location is
-          positioned at the rightmost point of the circle.
-
-    `\D'C D''
-          Draw a solid circle with the same parameters and behaviour as
-          an outlined circle.  No outline is drawn.
-
-    `\D'e X Y''
-          Draw an ellipse with a horizontal diameter of X and a vertical
-          diameter of Y with the leftmost point at the current position.
-          After drawing, the current location is positioned at the
-          rightmost point of the ellipse.
-
-    `\D'E X Y''
-          Draw a solid ellipse with the same parameters and behaviour
-          as an outlined ellipse.  No outline is drawn.
-
-    `\D'a DX1 DY1 DX2 DY2''
-          Draw an arc clockwise from the current location through the
-          two specified relative locations (DX1,DY1) and (DX2,DY2).
-          The coordinates of the first point are relative to the
-          current position, and the coordinates of the second point are
-          relative to the first point.  After drawing, the current
-          position is moved to the final point of the arc.
-
-    `\D'~ DX1 DY1 DX2 DY2 ...''
-          Draw a spline from the current location to the relative point
-          (DX1,DY1) and then to (DX2,DY2), and so on.  The current
-          position is moved to the terminal point of the drawn curve.
-
-    `\D'f N''
-          Set the shade of gray to be used for filling solid objects
-          to N; N must be an integer between 0 and 1000, where 0
-          corresponds solid white and 1000 to solid black, and values
-          in between correspond to intermediate shades of gray.  This
-          applies only to solid circles, solid ellipses, and solid
-          polygons.  By default, a level of 1000 is used.
-
-          Despite of being silly, the current point is moved
-          horizontally to the right by N.
-
-          Don't use this command!  It has the serious drawback that it
-          will be always rounded to the next integer multiple of the
-          horizontal resolution (the value of the `hor' keyword in the
-          `DESC' file).  Use `\M' (*note Colors::) or `\D'Fg ...''
-          instead.
-
-    `\D'p DX1 DY1 DX2 DY2 ...''
-          Draw a polygon from the current location to the relative
-          position (DX1,DY1) and then to (DX2,DY2) and so on.  When the
-          specified data points are exhausted, a line is drawn back to
-          the starting point.  The current position is changed by
-          adding the sum of all arguments with odd index to the actual
-          horizontal position and the even ones to the vertical
-          position.
-
-    `\D'P DX1 DY1 DX2 DY2 ...''
-          Draw a solid polygon with the same parameters and behaviour
-          as an outlined polygon.  No outline is drawn.
-
-          Here a better variant of the box macro to fill the box with
-          some color.  Note that the box must be drawn before the text
-          since colors in `gtroff' are not transparent; the filled
-          polygon would hide the text completely.
-
-
-               .de BOX
-               .  nr @wd \w'\\$1'
-               \h'.2m'\
-               \h'-.2m'\v'(.2m - \\n[rsb]u)'\
-               \M[lightcyan]\
-               \D'P 0 -(\\n[rst]u - \\n[rsb]u + .4m) \
-                    (\\n[@wd]u + .4m) 0 \
-                    0 (\\n[rst]u - \\n[rsb]u + .4m) \
-                    -(\\n[@wd]u + .4m) 0'\
-               \h'.2m'\v'-(.2m - \\n[rsb]u)'\
-               \M[]\
-               \\$1\
-               \h'.2m'
-               ..
-
-    `\D't N''
-          Set the current line thickness to N machine units.  A value of
-          zero selects the smallest available line thickness.  A
-          negative value makes the line thickness proportional to the
-          current point size (this is the default behaviour of AT&T
-          `troff').
-
-          Despite of being silly, the current point is moved
-          horizontally to the right by N.
-
-    `\D'FSCHEME COLOR_COMPONENTS''
-          Change current fill color.  SCHEME is a single letter
-          denoting the color scheme: `r' (rgb), `c' (cmy), `k' (cmyk),
-          `g' (gray), or `d' (default color).  The color components use
-          exactly the same syntax as in the `defcolor' request (*note
-          Colors::); the command `\D'Fd'' doesn't take an argument.
-
-          _No_ position changing!
-
-          Examples:
-
-
-          \D'Fg .3'      \" same gray as \D'f 700' \D'Fr #0000ff' \"
-          blue
-
-   *Note Graphics Commands::.
-
- -- Escape: \b'string'
-     "Pile" a sequence of glyphs vertically, and center it vertically
-     on the current line.  Use it to build large brackets and braces.
-
-     Here an example how to create a large opening brace:
-
-
-          \b'\[lt]\[bv]\[lk]\[bv]\[lb]'
-
-     The first glyph is on the top, the last glyph in STRING is at the
-     bottom.  Note that `gtroff' separates the glyphs vertically by 1m,
-     and the whole object is centered 0.5m above the current baseline;
-     the largest glyph width is used as the width for the whole object.
-     This rather unflexible positioning algorithm doesn't work with
-     `-Tdvi' since the bracket pieces vary in height for this device.
-     Instead, use the `eqn' preprocessor.
-
-     *Note Manipulating Spacing::, how to adjust the vertical spacing
-     with the `\x' escape.

-5.24 Traps
-==========
-
-"Traps" are locations, which, when reached, call a specified macro.
-These traps can occur at a given location on the page, at a given
-location in the current diversion, at a blank line, after a certain
-number of input lines, or at the end of input.
-
-   Setting a trap is also called "planting".  It is also said that a

-     them otherwise.  Vertical position traps are traps set by the `wh'
-     or `dt' requests.  Traps set by the `it' request are not vertical
-     position traps.  The parameter that controls whether vertical
-     position traps are enabled is global.  Initially vertical position
-     traps are enabled.  The current setting of this is available in the
-     `.vpt' read-only number register.
-
-     Note that a page can't be ejected if `vpt' is set to zero.
-
- -- Request: .wh dist [macro]
-     Set a page location trap.  Non-negative values for DIST set the
-     trap relative to the top of the page; negative values set the trap
-     relative to the bottom of the page.  Default scaling indicator is
-     `v'.
-
-     MACRO is the name of the macro to execute when the trap is sprung.
-     If MACRO is missing, remove the first trap (if any) at DIST.
-
-     The following is a simple example of how many macro packages set
-     headers and footers.
-
-
-          .de hd                \" Page header
-          '  sp .5i
-          .  tl 'Title''date'
-          '  sp .3i
-          ..
-          .
-          .de fo                \" Page footer
-          '  sp 1v
-          .  tl ''%''
-          '  bp
-          ..
-          .
-          .wh 0   hd            \" trap at top of the page
-          .wh -1i fo            \" trap one inch from bottom
-
-     A trap at or below the bottom of the page is ignored; it can be
-     made active by either moving it up or increasing the page length
-     so that the trap is on the page.
-
-     It is possible to have more than one trap at the same location; to
-     do so, the traps must be defined at different locations, then
-     moved together with the `ch' request; otherwise the second trap
-     would replace the first one.  Earlier defined traps hide later
-     defined traps if moved to the same position (the many empty lines
-     caused by the `bp' request are omitted in the following example):
-
-
-          .de a
-          .  nop a
-          ..
-          .de b
-          .  nop b
-          ..
-          .de c
-          .  nop c
-          ..
-          .
-          .wh 1i a
-          .wh 2i b
-          .wh 3i c
-          .bp
-              => a b c
-
-
-          .ch b 1i
-          .ch c 1i
-          .bp
-              => a
-
-
-          .ch a 0.5i
-          .bp
-              => a b
-
-
- -- Register: \n[.t]
-     A read-only number register holding the distance to the next trap.
-
-     If there are no traps between the current position and the bottom
-     of the page, it contains the distance to the page bottom.  In a
-     diversion, the distance to the page bottom is infinite (the
-     returned value is the biggest integer which can be represented in
-     `groff') if there are no diversion traps.
-
- -- Request: .ch macro [dist]
-     Change the location of a trap.  The first argument is the name of
-     the macro to be invoked at the trap, and the second argument is
-     the new location for the trap (note that the parameters are
-     specified in opposite order as in the `wh' request).  This is
-     useful for building up footnotes in a diversion to allow more
-     space at the bottom of the page for them.
-
-     Default scaling indicator for DIST is `v'.  If DIST is missing,
-     the trap is removed.
-
-
- -- Register: \n[.ne]
-     The read-only number register `.ne' contains the amount of space
-     that was needed in the last `ne' request that caused a trap to be
-     sprung.  Useful in conjunction with the `.trunc' register.  *Note
-     Page Control::, for more information.
-
-     Since the `.ne' register is only set by traps it doesn't make much
-     sense to use it outside of trap macros.
-
- -- Register: \n[.trunc]
-     A read-only register containing the amount of vertical space
-     truncated by the most recently sprung vertical position trap, or,
-     if the trap was sprung by an `ne' request, minus the amount of
-     vertical motion produced by the `ne' request.  In other words, at
-     the point a trap is sprung, it represents the difference of what
-     the vertical position would have been but for the trap, and what
-     the vertical position actually is.
-
-     Since the `.trunc' register is only set by traps it doesn't make
-     much sense to use it outside of trap macros.
-
- -- Register: \n[.pe]
-     A read-only register which is set to 1 while a page is ejected with
-     the `bp' request (or by the end of input).
-
-     Outside of traps this register is always zero.  In the following
-     example, only the second call to `x' is caused by `bp'.
-
-
-          .de x
-          \&.pe=\\n[.pe]
-          .br
-          ..
-          .wh 1v x
-          .wh 4v x
-          A line.
-          .br
-          Another line.
-          .br
-              => A line.
-                 .pe=0
-                 Another line.
-
-                 .pe=1
-
-
-   An important fact to consider while designing macros is that
-diversions and traps do not interact normally.  For example, if a trap
-invokes a header macro (while outputting a diversion) which tries to
-change the font on the current page, the effect will not be visible
-before the diversion has completely been printed (except for input
-protected with `\!' or `\?') since the data in the diversion is already
-formatted.  In most cases, this is not the expected behaviour.

-5.24.2 Diversion Traps
-----------------------
-
- -- Request: .dt [dist macro]
-     Set a trap _within_ a diversion.  DIST is the location of the trap
-     (identical to the `wh' request; default scaling indicator is `v')
-     and MACRO is the name of the macro to be invoked.  If called
-     without arguments, the diversion trap is removed.
-
-     Note that there exists only a single diversion trap.
-
-     The number register `.t' still works within diversions.  *Note
-     Diversions::, for more information.

-
-5.24.3 Input Line Traps
------------------------
-
- -- Request: .it n macro
- -- Request: .itc n macro
-     Set an input line trap.  N is the number of lines of input which
-     may be read before springing the trap, MACRO is the macro to be
-     invoked.  Request lines are not counted as input lines.
-
-     For example, one possible use is to have a macro which prints the
-     next N lines in a bold font.
-
-
-          .de B
-          .  it \\$1 B-end
-          .  ft B
-          ..
-          .
-          .de B-end
-          .  ft R
-          ..
-
-     The `itc' request is identical except that an interrupted text
-     line (ending with `\c') is not counted as a separate line.
-
-     Both requests are associated with the current environment (*note
-     Environments::); switching to another environment disables the
-     current input trap, and going back reactivates it, restoring the
-     number of already processed lines.

-5.24.4 Blank Line Traps

-
- -- Request: .em macro
-     Set a trap at the end of input.  MACRO is executed after the last
-     line of the input file has been processed.
-
-     For example, if the document had to have a section at the bottom
-     of the last page for someone to approve it, the `em' request could
-     be used.

-5.25 Diversions
-===============
-
-In `gtroff' it is possible to "divert" text into a named storage area.
-Due to the similarity to defining macros it is sometimes said to be
-stored in a macro.  This is used for saving text for output at a later
-time, which is useful for keeping blocks of text on the same page,
-footnotes, tables of contents, and indices.
-
-   For orthogonality it is said that `gtroff' is in the "top-level
-diversion" if no diversion is active (i.e., the data is diverted to the
-output device).
-
- -- Request: .di macro
- -- Request: .da macro
-     Begin a diversion.  Like the `de' request, it takes an argument of
-     a macro name to divert subsequent text into.  The `da' macro
-     appends to an existing diversion.
-
-     `di' or `da' without an argument ends the diversion.
-
- -- Request: .box macro
- -- Request: .boxa macro
-     Begin (or appends to) a diversion like the `di' and `da' requests.
-     The difference is that `box' and `boxa' do not include a
-     partially-filled line in the diversion.
-
-     Compare this:
-
-
-          Before the box.
-          .box xxx
-          In the box.
-          .br
-          .box
-          After the box.
-          .br
-              => Before the box.  After the box.
-          .xxx
-              => In the box.
-
-     with this:
-
-
-          Before the diversion.
-          .di yyy
-          In the diversion.
-          .br
-          .di
-          After the diversion.
-          .br
-              => After the diversion.
-          .yyy
-              => Before the diversion.  In the diversion.
-
-     `box' or `boxa' without an argument ends the diversion.
-
- -- Register: \n[.z]
- -- Register: \n[.d]
-     Diversions may be nested.  The read-only number register `.z'
-     contains the name of the current diversion (this is a string-valued
-     register).  The read-only number register `.d' contains the current
-     vertical place in the diversion.  If not in a diversion it is the
-     same as register `nl'.
-
- -- Register: \n[.h]
-     The "high-water mark" on the current page.  It corresponds to the
-     text baseline of the lowest line on the page.  This is a read-only
-     register.
-
-
-          .tm .h==\n[.h], nl==\n[nl]
-              => .h==0, nl==-1
-          This is a test.
-          .br
-          .sp 2
-          .tm .h==\n[.h], nl==\n[nl]
-              => .h==40, nl==120
-
-     As can be seen in the previous example, empty lines are not
-     considered in the return value of the `.h' register.
-
- -- Register: \n[dn]
- -- Register: \n[dl]
-     After completing a diversion, the read-write number registers `dn'
-     and `dl' contain the vertical and horizontal size of the diversion.
-     Note that only the just processed lines are counted: For the
-     computation of `dn' and `dl', the requests `da' and `boxa' are
-     handled as if `di' and `box' had been used - lines which have been
-     already stored in a macro are not taken into account.

-          .ec
-
-
- -- Escape: \!
- -- Escape: \?anything\?
-     Prevent requests, macros, and escapes from being interpreted when
-     read into a diversion.  Both escapes take the given text and
-     "transparently" embed it into the diversion.  This is useful for
-     macros which shouldn't be invoked until the diverted text is
-     actually output.
-
-     The `\!' escape transparently embeds text up to and including the
-     end of the line.  The `\?' escape transparently embeds text until
-     the next occurrence of the `\?' escape.  Example:
-
-
-          \?ANYTHING\?
-
-     ANYTHING may not contain newlines; use `\!'  to embed newlines in
-     a diversion.  The escape sequence `\?' is also recognized in copy
-     mode and turned into a single internal code; it is this code that
-     terminates ANYTHING.  Thus the following example prints 4.
-
-
-          .nr x 1
-          .nf
-          .di d
-          \?\\?\\\\?\\\\\\\\nx\\\\?\\?\?
-          .di
-          .nr x 2
-          .di e
-          .d
-          .di
-          .nr x 3
-          .di f
-          .e
-          .di
-          .nr x 4
-          .f
-
-     Both escapes read the data in copy mode.
-
-     If `\!' is used in the top-level diversion, its argument is
-     directly embedded into the `gtroff' intermediate output.  This can
-     be used for example to control a postprocessor which processes the
-     data before it is sent to the device driver.
-
-     The `\?' escape used in the top-level diversion produces no output
-     at all; its argument is simply ignored.
-
- -- Request: .output string
-     Emit STRING directly to the `gtroff' intermediate output (subject
-     to copy-mode interpretation); this is similar to `\!' used at the
-     top level.  An initial double quote in STRING is stripped off to
-     allow initial blanks.
-
-     This request can't be used before the first page has started - if
-     you get an error, simply insert `.br' before the `output' request.
-
-     Without argument, `output' is ignored.
-
-     Use with caution!  It is normally only needed for mark-up used by a
-     postprocessor which does something with the output before sending
-     it to the output device, filtering out STRING again.
-
- -- Request: .asciify div
-     "Unformat" the diversion specified by DIV in such a way that ASCII
-     characters, characters translated with the `trin' request, space
-     characters, and some escape sequences that were formatted and
-     diverted are treated like ordinary input characters when the
-     diversion is reread.  It can be also used for gross hacks; for
-     example, the following sets register `n' to 1.
-
-
-          .tr @.
-          .di x
-          @nr n 1
-          .br
-          .di
-          .tr @@
-          .asciify x
-          .x
-
-     *Note Copy-in Mode::.
-
- -- Request: .unformat div
-     Like `asciify', unformat the specified diversion.  However,
-     `unformat' only unformats spaces and tabs between words.
-     Unformatted tabs are treated as input tokens, and spaces are
-     stretchable again.
-
-     The vertical size of lines is not preserved; glyph information
-     (font, font size, space width, etc.) is retained.

-5.26 Environments
-=================
-
-It happens frequently that some text should be printed in a certain
-format regardless of what may be in effect at the time, for example, in
-a trap invoked macro to print headers and footers.  To solve this
-`gtroff' processes text in "environments".  An environment contains
-most of the parameters that control text processing.  It is possible to
-switch amongst these environments; by default `gtroff' processes text
-in environment 0.  The following is the information kept in an
-environment.
-
-   * font parameters (size, family, style, glyph height and slant, space
-     and sentence space size)
-
-   * page parameters (line length, title length, vertical spacing, line
-     spacing, indentation, line numbering, centering, right-justifying,
-     underlining, hyphenation data)
-
-   * fill and adjust mode
-
-   * tab stops, tab and leader characters, escape character, no-break
-     and hyphen indicators, margin character data
-
-   * partially collected lines
-
-   * input traps
-
-   * drawing and fill colours
-
-   These environments may be given arbitrary names (see *Note
-Identifiers::, for more info).  Old versions of `troff' only had
-environments named `0', `1', and `2'.
-
- -- Request: .ev [env]
- -- Register: \n[.ev]
-     Switch to another environment.  The argument ENV is the name of
-     the environment to switch to.  With no argument, `gtroff' switches
-     back to the previous environment.  There is no limit on the number
-     of named environments; they are created the first time that they
-     are referenced.  The `.ev' read-only register contains the name or
-     number of the current environment.  This is a string-valued
-     register.
-
-     Note that a call to `ev' (with argument) pushes the previously
-     active environment onto a stack.  If, say, environments `foo',
-     `bar', and `zap' are called (in that order), the first `ev'
-     request without parameter switches back to environment `bar'
-     (which is popped off the stack), and a second call switches back
-     to environment `foo'.
-
-     Here is an example:
-
-
-          .ev footnote-env
-          .fam N
-          .ps 6
-          .vs 8
-          .ll -.5i
-          .ev
-
-          ...
-
-          .ev footnote-env
-          \(dg Note the large, friendly letters.
-          .ev
-
-
- -- Request: .evc env
-     Copy the environment ENV into the current environment.
-
-     The following environment data is not copied:
-
-        * Partially filled lines.
-
-        * The status whether the previous line was interrupted.
-
-        * The number of lines still to center, or to right-justify, or
-          to underline (with or without underlined spaces); they are
-          set to zero.
-
-        * The status whether a temporary indentation is active.
-
-        * Input traps and its associated data.
-
-        * Line numbering mode is disabled; it can be reactivated with
-          `.nm +0'.
-
-        * The number of consecutive hyphenated lines (set to zero).
-
- -- Register: \n[.w]
- -- Register: \n[.cht]
- -- Register: \n[.cdp]
- -- Register: \n[.csk]

-     to the current environment.
-
-     The `\n[.cht]' register contains the height of the last glyph
-     added to the current environment.
-

-
-     The `\n[.csk]' register contains the "skew" (how far to the right

-     last glyph added to the current environment.

-5.27 Suppressing output
-=======================
-
- -- Escape: \Onum
-     Disable or enable output depending on the value of NUM:
-
-    `\O0'
-          Disable any glyphs from being emitted to the device driver,
-          provided that the escape occurs at the outer level (see
-          `\O[3]' and `\O[4]').  Motion is not suppressed so
-          effectively `\O[0]' means _pen up_.
-
-    `\O1'
-          Enable output of glyphs, provided that the escape occurs at
-          the outer level.
-
-     `\O0' and `\O1' also reset the four registers `opminx', `opminy',
-     `opmaxx', and `opmaxy' to -1.  *Note Register Index::.  These four
-     registers mark the top left and bottom right hand corners of a box
-     which encompasses all written glyphs.
-
-     For example the input text:
-
-
-          Hello \O[0]world \O[1]this is a test.
-
-     produces the following output:
-
-
-          Hello       this is a test.
-
-    `\O2'
-          Provided that the escape occurs at the outer level, enable
-          output of glyphs and also write out to `stderr' the page
-          number and four registers encompassing the glyphs previously
-          written since the last call to `\O'.
-
-    `\O3'
-          Begin a nesting level.  At start-up, `gtroff' is at outer
-          level.
-
-    `\O4'
-          End a nesting level.
-
-    `\O[5PFILENAME]'
-          This escape is `grohtml' specific.  Provided that this escape
-          occurs at the outer nesting level write the `filename' to
-          `stderr'.  The position of the image, P, must be specified
-          and must be one of `l', `r', `c', or `i' (left, right,
-          centered, inline).  FILENAME will be associated with the
-          production of the next inline image.

-5.28 Colors
-===========
-
- -- Request: .color [n]
- -- Register: \n[.color]
-     If N is missing or non-zero, activate colors (this is the default);
-     otherwise, turn it off.
-
-     The read-only number register `.color' is 1 if colors are active,
-     0 otherwise.
-
-     Internally, `color' sets a global flag; it does not produce a
-     token.  Similar to the `cp' request, you should use it at the
-     beginning of your document to control color output.
-
-     Colors can be also turned off with the `-c' command line option.
-
- -- Request: .defcolor ident scheme color_components
-     Define color with name IDENT.  SCHEME can be one of  the following
-     values: `rgb' (three components), `cmy' (three components), `cmyk'
-     (four components), and `gray' or `grey' (one component).
-
-     Color components can be given either as a hexadecimal string or as
-     positive decimal integers in the range 0-65535.  A hexadecimal
-     string contains all color components concatenated.  It must start
-     with either `#' or `##'; the former specifies hex values in the
-     range 0-255 (which are internally multiplied by 257), the latter
-     in the range 0-65535.  Examples: `#FFC0CB' (pink), `##ffff0000ffff'
-     (magenta).  The default color name value is device-specific
-     (usually black).  It is possible that the default color for `\m'
-     and `\M' is not identical.
-
-     A new scaling indicator `f' has been introduced which multiplies
-     its value by 65536; this makes it convenient to specify color
-     components as fractions in the range 0 to 1 (1f equals 65536u).
-     Example:
-
-
-          .defcolor darkgreen rgb 0.1f 0.5f 0.2f
-
-     Note that `f' is the default scaling indicator for the `defcolor'
-     request, thus the above statement is equivalent to
-
-
-          .defcolor darkgreen rgb 0.1 0.5 0.2
-
-
- -- Request: .gcolor [color]
- -- Escape: \mc
- -- Escape: \m(co
- -- Escape: \m[color]
- -- Register: \n[.m]
-     Set (glyph) drawing color.  The following examples show how to
-     turn the next four words red.
-
-
-          .gcolor red
-          these are in red
-          .gcolor
-          and these words are in black.
-
-
-          \m[red]these are in red\m[] and these words are in black.
-
-     The escape `\m[]' returns to the previous color, as does a call to
-     `gcolor' without an argument.
-
-     The name of the current drawing color is available in the
-     read-only, string-valued number register `.m'.
-
-     The drawing color is associated with the current environment
-     (*note Environments::).
-
-     Note that `\m' doesn't produce an input token in `gtroff'.  As a
-     consequence, it can be used in requests like `mc' (which expects a
-     single character as an argument) to change the color on the fly:
-
-
-          .mc \m[red]x\m[]
-
-
- -- Request: .fcolor [color]
- -- Escape: \Mc
- -- Escape: \M(co
- -- Escape: \M[color]
- -- Register: \n[.M]
-     Set fill (background) color for filled objects drawn with the
-     `\D'...'' commands.
-
-     A red ellipse can be created with the following code:
-
-
-          \M[red]\h'0.5i'\D'E 2i 1i'\M[]
-
-     The escape `\M[]' returns to the previous fill color, as does a
-     call to `fcolor' without an argument.
-
-     The name of the current fill (background) color is available in the
-     read-only, string-valued number register `.M'.
-
-     The fill color is associated with the current environment (*note
-     Environments::).
-
-     Note that `\M' doesn't produce an input token in `gtroff'.

-5.29 I/O
-========
-
-`gtroff' has several requests for including files:
-
- -- Request: .so file
-     Read in the specified FILE and includes it in place of the `so'
-     request.  This is quite useful for large documents, e.g. keeping
-     each chapter in a separate file.  *Note gsoelim::, for more
-     information.
-
-     Since `gtroff' replaces the `so' request with the contents of
-     `file', it makes a difference whether the data is terminated with
-     a newline or not: Assuming that file `xxx' contains the word `foo'
-     without a final newline, this
-
-
-          This is
-          .so xxx
-          bar
-
-     yields `This is foobar'.
-
-     The search path for FILE can be controlled with the `-I' command
-     line option.
-
- -- Request: .pso command
-     Read the standard output from the specified COMMAND and includes
-     it in place of the `pso' request.
-
-     This request causes an error if used in safer mode (which is the
-     default).  Use `groff''s or `troff''s `-U' option to activate
-     unsafe mode.
-
-     The comment regarding a final newline for the `so' request is valid
-     for `pso' also.
-
- -- Request: .mso file
-     Identical to the `so' request except that `gtroff' searches for
-     the specified FILE in the same directories as macro files for the
-     the `-m' command line option.  If the file name to be included has
-     the form `NAME.tmac' and it isn't found, `mso' tries to include
-     `tmac.NAME' and vice versa.
-
- -- Request: .trf file
- -- Request: .cf file
-     Transparently output the contents of FILE.  Each line is output as
-     if it were preceded by `\!'; however, the lines are not subject to
-     copy mode interpretation.  If the file does not end with a newline,
-     then a newline is added (`trf' only).  For example, to define a
-     macro `x' containing the contents of file `f', use
-
-
-          .di x
-          .trf f
-          .di
-
-     Both `trf' and `cf', when used in a diversion, embeds an object in
-     the diversion which, when reread, causes the contents of FILE to
-     be transparently copied through to the output.  In UNIX `troff',
-     the contents of FILE is immediately copied through to the output
-     regardless of whether there is a current diversion; this behaviour
-     is so anomalous that it must be considered a bug.
-
-     While `cf' copies the contents of FILE completely unprocessed,
-     `trf' disallows characters such as NUL that are not valid `gtroff'
-     input characters (*note Identifiers::).
-
-     Both requests cause a line break.
-
- -- Request: .nx [file]
-     Force `gtroff' to continue processing of the file specified as an
-     argument.  If no argument is given, immediately jump to the end of
-     file.
-
- -- Request: .rd [prompt [arg1 arg2 ...]]
-     Read from standard input, and include what is read as though it
-     were part of the input file.  Text is read until a blank line is
-     encountered.
-
-     If standard input is a TTY input device (keyboard), write PROMPT
-     to standard error, followed by a colon (or send BEL for a beep if
-     no argument is given).
-
-     Arguments after PROMPT are available for the input.  For example,
-     the line
-
-
-          .rd data foo bar
-
-     with the input `This is \$2.' prints
-
-
-          This is bar.
-
-
-   Using the `nx' and `rd' requests, it is easy to set up form letters.
-The form letter template is constructed like this, putting the
-following lines into a file called `repeat.let':
-
-
-     .ce
-     \*(td
-     .sp 2
-     .nf
-     .rd
-     .sp
-     .rd
-     .fi
-     Body of letter.
-     .bp
-     .nx repeat.let
-
-When this is run, a file containing the following lines should be
-redirected in.  Note that requests included in this file are executed
-as though they were part of the form letter.  The last block of input
-is the `ex' request which tells `groff' to stop processing.  If this
-was not there, `groff' would not know when to stop.

-     San Diego, CA  92103
-
-     Dear Mr. Adollar,
-
-     .ex
-
- -- Request: .pi pipe
-     Pipe the output of `gtroff' to the shell command(s) specified by
-     PIPE.  This request must occur before `gtroff' has a chance to
-     print anything.
-
-     `pi' causes an error if used in safer mode (which is the default).
-     Use `groff''s or `troff''s `-U' option to activate unsafe mode.
-
-     Multiple calls to `pi' are allowed, acting as a chain.  For
-     example,
-
-
-          .pi foo
-          .pi bar
-          ...
-
-     is the same as `.pi foo | bar'.
-
-     Note that the intermediate output format of `gtroff' is piped to
-     the specified commands.  Consequently, calling `groff' without the
-     `-Z' option normally causes a fatal error.
-
- -- Request: .sy cmds
- -- Register: \n[systat]
-     Execute the shell command(s) specified by CMDS.  The output is not
-     saved anyplace, so it is up to the user to do so.
-
-     This request causes an error if used in safer mode (which is the
-     default).  Use `groff''s or `troff''s `-U' option to activate
-     unsafe mode.
-
-     For example, the following code fragment introduces the current
-     time into a document:
-
-
-          .sy perl -e 'printf ".nr H %d\\n.nr M %d\\n.nr S %d\\n",\
-                       (localtime(time))[2,1,0]' > /tmp/x\n[$$]
-          .so /tmp/x\n[$$]
-          .sy rm /tmp/x\n[$$]
-          \nH:\nM:\nS
-
-     Note that this works by having the `perl' script (run by `sy')
-     print out the `nr' requests which set the number registers `H',
-     `M', and `S', and then reads those commands in with the `so'
-     request.
-
-     For most practical purposes, the number registers `seconds',
-     `minutes', and `hours' which are initialized at start-up of
-     `gtroff' should be sufficient.  Use the `af' request to get a
-     formatted output:
-
-
-          .af hours 00
-          .af minutes 00
-          .af seconds 00
-          \n[hours]:\n[minutes]:\n[seconds]
-
-     The `systat' read-write number register contains the return value
-     of the `system()' function executed by the last `sy' request.
-
- -- Request: .open stream file
- -- Request: .opena stream file
-     Open the specified FILE for writing and associates the specified
-     STREAM with it.
-
-     The `opena' request is like `open', but if the file exists, append
-     to it instead of truncating it.
-
-     Both `open' and `opena' cause an error if used in safer mode
-     (which is the default).  Use `groff''s or `troff''s `-U' option to
-     activate unsafe mode.
-
- -- Request: .write stream data
- -- Request: .writec stream data
-     Write to the file associated with the specified STREAM.  The
-     stream must previously have been the subject of an open request.
-     The remainder of the line is interpreted as the `ds' request reads
-     its second argument: A leading `"' is stripped, and it is read in
-     copy-in mode.
-
-     The `writec' request is like `write', but only `write' appends a
-     newline to the data.
-
- -- Request: .writem stream xx
-     Write the contents of the macro or string XX to the file
-     associated with the specified STREAM.
-
-     XX is read in copy mode, i.e., already formatted elements are
-     ignored.  Consequently, diversions must be unformatted with the
-     `asciify' request before calling `writem'.  Usually, this means a
-     loss of information.
-
- -- Request: .close stream
-     Close the specified STREAM; the stream is no longer an acceptable
-     argument to the `write' request.
-
-     Here a simple macro to write an index entry.
-
-
-          .open idx test.idx
-          .
-          .de IX
-          .  write idx \\n[%] \\$*
-          ..
-          .
-          .IX test entry
-          .
-          .close idx
-
-
- -- Escape: \Ve
- -- Escape: \V(ev
- -- Escape: \V[env]
-     Interpolate the contents of the specified environment variable ENV
-     (one-character name E, two-character name EV) as returned by the
-     function `getenv'.  `\V' is interpreted in copy-in mode.

-
-5.30 Postprocessor Access
-=========================
-
-There are two escapes which give information directly to the
-postprocessor.  This is particularly useful for embedding POSTSCRIPT
-into the final document.
-
- -- Escape: \X'xxx'
-     Embeds its argument into the `gtroff' output preceded with `x X'.
-
-     The escapes `\&', `\)', `\%', and `\:' are ignored within `\X',
-     `\ ' and `\~' are converted to single space characters.  All other
-     escapes (except `\\' which produces a backslash) cause an error.
-
-     If the `use_charnames_in_special' keyword is set in the `DESC'
-     file, special characters no longer cause an error; the name XX is
-     represented as `\(XX)' in the `x X' output command.  Additionally,
-     the backslash is represented as `\\'.
-
-     `use_charnames_in_special' is currently used by `grohtml' only.
-
- -- Escape: \Yn
- -- Escape: \Y(nm
- -- Escape: \Y[name]
-     This is approximately equivalent to `\X'\*[NAME]'' (one-character
-     name N, two-character name NM).  However, the contents of the
-     string or macro NAME are not interpreted; also it is permitted for
-     NAME to have been defined as a macro and thus contain newlines (it
-     is not permitted for the argument to `\X' to contain newlines).
-     The inclusion of newlines requires an extension to the UNIX `troff'
-     output format, and confuses drivers that do not know about this
-     extension (*note Device Control Commands::).
-
-   *Note Output Devices::.

-5.31 Miscellaneous
-==================
-
-This section documents parts of `gtroff' which cannot (yet) be
-categorized elsewhere in this manual.
-
- -- Request: .nm [start [inc [space [indent]]]]
-     Print line numbers.  START is the line number of the _next_ output
-     line.  INC indicates which line numbers are printed.  For example,
-     the value 5 means to emit only line numbers which are multiples
-     of 5; this defaults to 1.  SPACE is the space to be left between
-     the number and the text; this defaults to one digit space.  The
-     fourth argument is the indentation of the line numbers, defaulting
-     to zero.  Both SPACE and INDENT are given as multiples of digit
-     spaces; they can be negative also.  Without any arguments, line
-     numbers are turned off.
-
-     `gtroff' reserves three digit spaces for the line number (which is
-     printed right-justified) plus the amount given by INDENT; the
-     output lines are concatenated to the line numbers, separated by
-     SPACE, and _without_ reducing the line length.  Depending on the
-     value of the horizontal page offset (as set with the `po'
-     request), line numbers which are longer than the reserved space
-     stick out to the left, or the whole line is moved to the right.
-
-     Parameters corresponding to missing arguments are not changed; any
-     non-digit argument (to be more precise, any argument starting with
-     a character valid as a delimiter for identifiers) is also treated
-     as missing.
-
-     If line numbering has been disabled with a call to `nm' without an
-     argument, it can be reactivated with `.nm +0', using the
-     previously active line numbering parameters.
-
-     The parameters of `nm' are associated with the current environment
-     (*note Environments::).  The current output line number is
-     available in the number register `ln'.
-
-
-          .po 1m
-          .ll 2i
-          This test shows how line numbering works with groff.
-          .nm 999
-          This test shows how line numbering works with groff.

-
-     And here the result:
-
-
-           This  test shows how
-           line numbering works
-           999 with   groff.   This
-          1000 test shows how  line
-          1001 numbering works with
-          1002 groff.
-                This test shows how
-                line      numbering
-           works  with  groff.
-           This test shows how
-          1005  line      numbering
-                works with groff.
-
-
- -- Request: .nn [skip]
-     Temporarily turn off line numbering.  The argument is the number
-     of lines not to be numbered; this defaults to 1.
-
- -- Request: .mc glyph [dist]
-     Print a "margin character" to the right of the text.(1) (*note
-     Miscellaneous-Footnote-1::)  The first argument is the glyph to be
-     printed.  The second argument is the distance away from the right
-     margin.  If missing, the previously set value is used; default is
-     10pt).  For text lines that are too long (that is, longer than the
-     text length plus DIST), the margin character is directly appended
-     to the lines.
-
-     With no arguments the margin character is turned off.  If this
-     occurs before a break, no margin character is printed.
-
-     For compatibility with AT&T `troff', a call to `mc' to set the
-     margin character can't be undone immediately; at least one line
-     gets a margin character.  Thus
-
-
-          .ll 1i
-          .mc \[br]
-          .mc
-          xxx
-          .br
-          xxx
-
-     produces
-
-
-          xxx        |
-          xxx
-
-     For empty lines and lines produced by the `tl' request no margin
-     character is emitted.
-
-     The margin character is associated with the current environment
-     (*note Environments::).
-
-     This is quite useful for indicating text that has changed, and, in
-     fact, there are programs available for doing this (they are called
-     `nrchbar' and `changebar' and can be found in any
-     `comp.sources.unix' archive).
-
-
-          .ll 3i
-          .mc |
-          This paragraph is highlighted with a margin
-          character.
-          .sp
-          Note that vertical space isn't marked.
-          .br
-          \&
-          .br
-          But we can fake it with `\&'.

-5.32 `gtroff' Internals
-=======================
-
-`gtroff' processes input in three steps.  One or more input characters
-are converted to an "input token".(1) (*note Gtroff
-Internals-Footnote-1::)  Then, one or more input tokens are converted
-to an "output node".  Finally, output nodes are converted to the
-intermediate output language understood by all output devices.
-
-   Actually, before step one happens, `gtroff' converts certain escape
-sequences into reserved input characters (not accessible by the user);
-such reserved characters are used for other internal processing also -
-this is the very reason why not all characters are valid input.  *Note
-Identifiers::, for more on this topic.
-
-   For example, the input string `fi\[:u]' is converted into a
-character token `f', a character token `i', and a special token `:u'
-(representing u umlaut).  Later on, the character tokens `f' and `i'
-are merged to a single output node representing the ligature glyph `fi'
-(provided the current font has a glyph for this ligature); the same
-happens with `:u'.  All output glyph nodes are `processed' which means
-that they are invariably associated with a given font, font size,
-advance width, etc.  During the formatting process, `gtroff' itself
-adds various nodes to control the data flow.
-
-   Macros, diversions, and strings collect elements in two chained
-lists: a list of input tokens which have been passed unprocessed, and a
-list of output nodes.  Consider the following the diversion.
-
-
-     .di xxx
-     a
-     \!b
-     c
-     .br
-     .di
-
-It contains these elements.
-
-node list            token list   element number
-line start node      --           1
-glyph node `a'       --           2
-word space node      --           3
---                   `b'          4
---                   `\n'         5
-glyph node `c'       --           6
-vertical size node   --           7
-vertical size node   --           8
---                   `\n'         9
-
-Elements 1, 7, and 8 are inserted by `gtroff'; the latter two (which
-are always present) specify the vertical extent of the last line,
-possibly modified by `\x'.  The `br' request finishes the current
-partial line, inserting a newline input token which is subsequently
-converted to a space when the diversion is reread.  Note that the word
-space node has a fixed width which isn't stretchable anymore.  To
-convert horizontal space nodes back to input tokens, use the `unformat'
-request.
-
-   Macros only contain elements in the token list (and the node list is
-empty); diversions and strings can contain elements in both lists.
-
-   Note that the `chop' request simply reduces the number of elements
-in a macro, string, or diversion by one.  Exceptions are "compatibility
-save" and "compatibility ignore" input tokens which are ignored.  The
-`substring' request also ignores those input tokens.
-
-   Some requests like `tr' or `cflags' work on glyph identifiers only;
-this means that the associated glyph can be changed without destroying
-this association.  This can be very helpful for substituting glyphs.
-In the following example, we assume that glyph `foo' isn't available by
-default, so we provide a substitution using the `fchar' request and map
-it to input character `x'.
-
-
-     .fchar \[foo] foo
-     .tr x \[foo]
-
-Now let us assume that we install an additional special font `bar'
-which has glyph `foo'.
-
-
-     .special bar
-     .rchar \[foo]
-
-Since glyphs defined with `fchar' are searched before glyphs in special
-fonts, we must call `rchar' to remove the definition of the fallback
-glyph.  Anyway, the translation is still active; `x' now maps to the
-real glyph `foo'.
-
-   Macro and request arguments preserve the compatibility mode:
-
-
-     .cp 1     \" switch to compatibility mode
-     .de xx
-     \\$1
-     ..
-     .cp 0     \" switch compatibility mode off
-     .xx caf\['e]
-         => café
-
-Since compatibility mode is on while `de' is called, the macro `xx'
-activates compatibility mode while executing.  Argument `$1' can still
-be handled properly because it inherits the compatibility mode status
-which was active at the point where `xx' is called.
-
-   After expansion of the parameters, the compatibility save and restore
-tokens are removed.

-5.33 Debugging
-==============
-
-`gtroff' is not easy to debug, but there are some useful features and
-strategies for debugging.
-
- -- Request: .lf line [filename]
-     Change the line number and optionally the file name `gtroff' shall
-     use for error and warning messages.  LINE is the input line number
-     of the _next_ line.
-
-     Without argument, the request is ignored.
-
-     This is a debugging aid for documents which are split into many
-     files, then put together with `soelim' and other preprocessors.
-     Usually, it isn't invoked manually.
-
-     Note that other `troff' implementations (including the original
-     AT&T version) handle `lf' differently.  For them, LINE changes the
-     line number of the _current_ line.
-
- -- Request: .tm string
- -- Request: .tm1 string
- -- Request: .tmc string
-     Send STRING to the standard error output; this is very useful for
-     printing debugging messages among other things.
-
-     STRING is read in copy mode.
-
-     The `tm' request ignores leading spaces of STRING; `tm1' handles
-     its argument similar to the `ds' request: a leading double quote
-     in STRING is stripped to allow initial blanks.
-
-     The `tmc' request is similar to `tm1' but does not append a
-     newline (as is done in `tm' and `tm1').
-
- -- Request: .ab [string]
-     Similar to the `tm' request, except that it causes `gtroff' to
-     stop processing.  With no argument it prints `User Abort.' to
-     standard error.
-
- -- Request: .ex
-     The `ex' request also causes `gtroff' to stop processing; see also
-     *Note I/O::.
-
-   When doing something involved it is useful to leave the debugging
-statements in the code and have them turned on by a command line flag.
-
-
-     .if \n(DB .tm debugging output
-
-To activate these statements say
-
-
-     groff -rDB=1 file
-
-   If it is known in advance that there will be many errors and no
-useful output, `gtroff' can be forced to suppress formatted output with
-the `-z' flag.
-
- -- Request: .pm
-     Print the entire symbol table on `stderr'.  Names of all defined
-     macros, strings, and diversions are print together with their size
-     in bytes.  Since `gtroff' sometimes adds nodes by itself, the
-     returned size can be larger than expected.
-
-     This request differs from UNIX `troff': `gtroff' reports the sizes
-     of diversions, ignores an additional argument to print only the
-     total of the sizes, and the size isn't returned in blocks of 128
-     characters.
-
- -- Request: .pnr
-     Print the names and contents of all currently defined number
-     registers on `stderr'.
-
- -- Request: .ptr
-     Print the names and positions of all traps (not including input
-     line traps and diversion traps) on `stderr'.  Empty slots in the
-     page trap list are printed as well, because they can affect the
-     priority of subsequently planted traps.
-
- -- Request: .fl
-     Instruct `gtroff' to flush its output immediately.  The intent is
-     for interactive use, but this behaviour is currently not
-     implemented in `gtroff'.  Contrary to UNIX `troff', TTY output is
-     sent to a device driver also (`grotty'), making it non-trivial to
-     communicate interactively.
-
-     This request causes a line break.
-
- -- Request: .backtrace
-     Print a backtrace of the input stack to the standard error stream.
-
-     Consider the following in file `test':
-
-
-          .de xxx
-          .  backtrace
-          ..
-          .de yyy
-          .  xxx
-          ..
-          .
-          .yyy
-
-     On execution, `gtroff' prints the following:
-
-
-          test:2: backtrace: macro `xxx'
-          test:5: backtrace: macro `yyy'
-          test:8: backtrace: file `test'
-
-     The option `-b' of `gtroff' internally calls a variant of this
-     request on each error and warning.
-
- -- Register: \n[slimit]
-     Use the `slimit' number register to set the maximum number of
-     objects on the input stack.  If `slimit' is less than or equal
-     to 0, there is no limit set.  With no limit, a buggy recursive
-     macro can exhaust virtual memory.
-
-     The default value is 1000; this is a compile-time constant.
-
- -- Request: .warnscale si
-     Set the scaling indicator used in warnings to SI.  Valid values for
-     SI are `u', `i', `c', `p', and `P'.  At startup, it is set to `i'.
-
- -- Request: .spreadwarn [limit]
-     Make `gtroff' emit a warning if the additional space inserted for
-     each space between words in an output line is larger or equal to
-     LIMIT.  A negative value is changed to zero; no argument toggles
-     the warning on and off without changing LIMIT.  The default scaling
-     indicator is `m'.  At startup, `spreadwarn' is deactivated, and
-     LIMIT is set to 3m.
-
-     For example,
-
-
-          .spreadwarn 0.2m
-
-     will cause a warning if `gtroff' must add 0.2m or more for each
-     interword space in a line.
-
-     This request is active only if text is justified to both margins
-     (using `.ad b').
-
-   `gtroff' has command line options for printing out more warnings
-(`-w') and for printing backtraces (`-b') when a warning or an error
-occurs.  The most verbose level of warnings is `-ww'.
-
- -- Request: .warn [flags]
- -- Register: \n[.warn]
-     Control the level of warnings checked for.  The FLAGS are the sum
-     of the numbers associated with each warning that is to be enabled;
-     all other warnings are disabled.  The number associated with each
-     warning is listed below.  For example, `.warn 0' disables all
-     warnings, and `.warn 1' disables all warnings except that about
-     missing glyphs.  If no argument is given, all warnings are enabled.
-
-     The read-only number register `.warn' contains the current warning
-     level.

-5.33.1 Warnings
----------------
-
-The warnings that can be given to `gtroff' are divided into the
-following categories.  The name associated with each warning is used by
-the `-w' and `-W' options; the number is used by the `warn' request and
-by the `.warn' register.
-
-`char'
-`1'
-     Non-existent glyphs.(1) (*note Warnings-Footnote-1::)  This is
-     enabled by default.
-
-`number'
-`2'
-     Invalid numeric expressions.  This is enabled by default.  *Note
-     Expressions::.
-
-`break'
-`4'
-     In fill mode, lines which could not be broken so that their length
-     was less than the line length.  This is enabled by default.
-
-`delim'
-`8'
-     Missing or mismatched closing delimiters.
-
-`el'
-`16'
-     Use of the `el' request with no matching `ie' request.  *Note
-     if-else::.
-
-`scale'
-`32'
-     Meaningless scaling indicators.
-
-`range'
-`64'
-     Out of range arguments.
-
-`syntax'
-`128'
-     Dubious syntax in numeric expressions.
-
-`di'
-`256'
-     Use of `di' or `da' without an argument when there is no current
-     diversion.
-
-`mac'
-`512'
-     Use of undefined strings, macros and diversions.  When an undefined
-     string, macro, or diversion is used, that string is automatically
-     defined as empty.  So, in most cases, at most one warning is given
-     for each name.
-
-`reg'
-`1024'
-     Use of undefined number registers.  When an undefined number
-     register is used, that register is automatically defined to have a
-     value of 0.  So, in most cases, at most one warning is given for
-     use of a particular name.
-
-`tab'
-`2048'
-     Use of a tab character where a number was expected.
-
-`right-brace'
-`4096'
-     Use of `\}' where a number was expected.
-
-`missing'
-`8192'
-     Requests that are missing non-optional arguments.
-
-`input'
-`16384'
-     Invalid input characters.
-
-`escape'
-`32768'
-     Unrecognized escape sequences.  When an unrecognized escape
-     sequence `\X' is encountered, the escape character is ignored, and
-     X is printed.
-
-`space'
-`65536'
-     Missing space between a request or macro and its argument.  This
-     warning is given when an undefined name longer than two characters
-     is encountered, and the first two characters of the name make a
-     defined name.  The request or macro is not invoked.  When this
-     warning is given, no macro is automatically defined.  This is
-     enabled by default.  This warning never occurs in compatibility
-     mode.
-
-`font'
-`131072'
-     Non-existent fonts.  This is enabled by default.
-
-`ig'
-`262144'
-     Invalid escapes in text ignored with the `ig' request.  These are
-     conditions that are errors when they do not occur in ignored text.
-
-`color'
-`524288'
-     Color related warnings.
-
-`all'
-     All warnings except `di', `mac' and `reg'.  It is intended that
-     this covers all warnings that are useful with traditional macro
-     packages.
-
-`w'
-     All warnings.

-5.34 Implementation Differences
-===============================
-
-GNU `troff' has a number of features which cause incompatibilities with
-documents written with old versions of `troff'.
-
-   Long names cause some incompatibilities.  UNIX `troff' interprets
-
-
-     .dsabcd
-
-as defining a string `ab' with contents `cd'.  Normally, GNU `troff'
-interprets this as a call of a macro named `dsabcd'.  Also UNIX `troff'
-interprets `\*[' or `\n[' as references to a string or number register
-called `['.  In GNU `troff', however, this is normally interpreted as
-the start of a long name.  In compatibility mode GNU `troff' interprets
-long names in the traditional way (which means that they are not
-recognized as names).
-
- -- Request: .cp [n]
- -- Request: .do cmd
- -- Register: \n[.C]
-     If N is missing or non-zero, turn on compatibility mode;
-     otherwise, turn it off.
-
-     The read-only number register `.C' is 1 if compatibility mode is
-     on, 0 otherwise.
-
-     Compatibility mode can be also turned on with the `-C' command line
-     option.
-
-     The `do' request turns off compatibility mode while executing its
-     arguments as a `gtroff' command.
-
-
-          .do fam T
-
-     executes the `fam' request when compatibility mode is enabled.
-
-     `gtroff' restores the previous compatibility setting before
-     interpreting any files sourced by the CMD.
-
-   Two other features are controlled by `-C'.  If not in compatibility
-mode, GNU `troff' preserves the input level in delimited arguments:
-
-
-     .ds xx '
-     \w'abc\*(xxdef'
-
-In compatibility mode, the string `72def'' is returned; without `-C'
-the resulting string is `168' (assuming a TTY output device).
-
-   Finally, the escapes `\f', `\H', `\m', `\M', `\R', `\s', and `\S'
-are transparent for recognizing the beginning of a line only in
-compatibility mode (this is a rather obscure feature).  For example,
-the code
-
-
-     .de xx
-     Hallo!
-     ..
-     \fB.xx\fP
-
-prints `Hallo!' in bold face if in compatibility mode, and `.xx' in
-bold face otherwise.
-
-   GNU `troff' does not allow the use of the escape sequences `\|',
-`\^', `\&', `\{', `\}', `\<SP>', `\'', `\`', `\-', `\_', `\!', `\%',
-and `\c' in names of strings, macros, diversions, number registers,
-fonts or environments; UNIX `troff' does.  The `\A' escape sequence
-(*note Identifiers::) may be helpful in avoiding use of these escape
-sequences in names.
-
-   Fractional point sizes cause one noteworthy incompatibility.  In
-UNIX `troff' the `ps' request ignores scale indicators and thus
-
-
-     .ps 10u
-
-sets the point size to 10 points, whereas in GNU `troff' it sets the
-point size to 10 scaled points.  *Note Fractional Type Sizes::, for
-more information.
-
-   In GNU `troff' there is a fundamental difference between
-(unformatted) input characters and (formatted) output glyphs.
-Everything that affects how a glyph is output is stored with the glyph
-node; once a glyph node has been constructed it is unaffected by any
-subsequent requests that are executed, including `bd', `cs', `tkf',
-`tr', or `fp' requests.  Normally glyphs are constructed from input
-characters at the moment immediately before the glyph is added to the
-current output line.  Macros, diversions and strings are all, in fact,
-the same type of object; they contain lists of input characters and
-glyph nodes in any combination.  A glyph node does not behave like an
-input character for the purposes of macro processing; it does not
-inherit any of the special properties that the input character from
-which it was constructed might have had.  For example,
-
-
-     .di x
-     \\\\
-     .br
-     .di
-     .x
-
-prints `\\' in GNU `troff'; each pair of input backslashes is turned
-into one output backslash and the resulting output backslashes are not
-interpreted as escape characters when they are reread.  UNIX `troff'
-would interpret them as escape characters when they were reread and
-would end up printing one `\'.  The correct way to obtain a printable
-backslash is to use the `\e' escape sequence: This always prints a
-single instance of the current escape character, regardless of whether
-or not it is used in a diversion; it also works in both GNU `troff' and
-UNIX `troff'.(1) (*note Implementation Differences-Footnote-1::)  To
-store, for some reason, an escape sequence in a diversion that will be
-interpreted when the diversion is reread, either use the traditional
-`\!' transparent output facility, or, if this is unsuitable, the new
-`\?' escape sequence.
-

-information.

-   (1) To be completely independent of the current escape character,
-use `\(rs' which represents a reverse solidus (backslash) glyph.

-8.1 `gtroff' Output
-===================
-
-This section describes the intermediate output format of GNU `troff'.
-This output is produced by a run of `gtroff' before it is fed into a
-device postprocessor program.
-
-   As `groff' is a wrapper program around `gtroff' that automatically
-calls a postprocessor, this output does not show up normally.  This is
-why it is called "intermediate".  `groff' provides the option `-Z' to
-inhibit postprocessing, such that the produced intermediate output is
-sent to standard output just like calling `gtroff' manually.
-
-   Here, the term "troff output" describes what is output by `gtroff',
-while "intermediate output" refers to the language that is accepted by
-the parser that prepares this output for the postprocessors.  This
-parser is smarter on whitespace and implements obsolete elements for
-compatibility, otherwise both formats are the same.(1) (*note gtroff
-Output-Footnote-1::)
-
-   The main purpose of the intermediate output concept is to facilitate
-the development of postprocessors by providing a common programming
-interface for all devices.  It has a language of its own that is
-completely different from the `gtroff' language.  While the `gtroff'
-language is a high-level programming language for text processing, the
-intermediate output language is a kind of low-level assembler language
-by specifying all positions on the page for writing and drawing.
-
-   The intermediate output produced by `gtroff' is fairly readable,
-while output from AT&T `troff' is rather hard to understand because of
-strange habits that are still supported, but not used any longer by
-`gtroff'.

-8.1.1 Language Concepts
------------------------
-
-During the run of `gtroff', the input data is cracked down to the
-information on what has to be printed at what position on the intended
-device.  So the language of the intermediate output format can be quite
-small.  Its only elements are commands with and without arguments.  In
-this section, the term "command" always refers to the intermediate
-output language, and never to the `gtroff' language used for document
-formatting.  There are commands for positioning and text writing, for
-drawing, and for device controlling.

-
-8.1.1.1 Separation
-..................
-
-AT&T `troff' output has strange requirements on whitespace.  The
-`gtroff' output parser, however, is smart about whitespace by making it
-maximally optional.  The whitespace characters, i.e., the tab, space,
-and newline characters, always have a syntactical meaning.  They are
-never printable because spacing within the output is always done by
-positioning commands.
-
-   Any sequence of space or tab characters is treated as a single
-"syntactical space".  It separates commands and arguments, but is only
-required when there would occur a clashing between the command code and
-the arguments without the space.  Most often, this happens when
-variable-length command names, arguments, argument lists, or command
-clusters meet.  Commands and arguments with a known, fixed length need
-not be separated by syntactical space.
-
-   A line break is a syntactical element, too.  Every command argument
-can be followed by whitespace, a comment, or a newline character.  Thus
-a "syntactical line break" is defined to consist of optional
-syntactical space that is optionally followed by a comment, and a
-newline character.
-
-   The normal commands, those for positioning and text, consist of a
-single letter taking a fixed number of arguments.  For historical
-reasons, the parser allows to stack such commands on the same line, but
-fortunately, in `gtroff''s intermediate output, every command with at
-least one argument is followed by a line break, thus providing
-excellent readability.
-
-   The other commands - those for drawing and device controlling - have
-a more complicated structure; some recognize long command names, and
-some take a variable number of arguments.  So all `D' and `x' commands
-were designed to request a syntactical line break after their last
-argument.  Only one command, `x X', has an argument that can stretch
-over several lines; all other commands must have all of their arguments
-on the same line as the command, i.e., the arguments may not be
-splitted by a line break.
-
-   Empty lines (these are lines containing only space and/or a
-comment), can occur everywhere.  They are just ignored.
-

-
-8.1.1.2 Argument Units
-......................
-
-Some commands take integer arguments that are assumed to represent
-values in a measurement unit, but the letter for the corresponding
-scale indicator is not written with the output command arguments.  Most
-commands assume the scale indicator `u', the basic unit of the device,
-some use `z', the scaled point unit of the device, while others, such
-as the color commands, expect plain integers.
-
-   Note that single characters can have the eighth bit set, as can the
-names of fonts and special characters.  The names of characters and
-fonts can be of arbitrary length.  A character that is to be printed
-will always be in the current font.
-
-   A string argument is always terminated by the next whitespace
-character (space, tab, or newline); an embedded `#' character is
-regarded as part of the argument, not as the beginning of a comment
-command.  An integer argument is already terminated by the next
-non-digit character, which then is regarded as the first character of
-the next argument or command.
-
-

-
-8.1.1.3 Document Parts
-......................
-
-A correct intermediate output document consists of two parts, the
-"prologue" and the "body".
-
-   The task of the prologue is to set the general device parameters
-using three exactly specified commands.  `gtroff''s prologue is
-guaranteed to consist of the following three lines (in that order):
-
-
-     x T DEVICE
-     x res N H V
-     x init
-
-with the arguments set as outlined in *Note Device Control Commands::.
-Note that the parser for the intermediate output format is able to
-swallow additional whitespace and comments as well even in the prologue.
-
-   The body is the main section for processing the document data.
-Syntactically, it is a sequence of any commands different from the ones
-used in the prologue.  Processing is terminated as soon as the first
-`x stop' command is encountered; the last line of any `gtroff'
-intermediate output always contains such a command.
-
-   Semantically, the body is page oriented.  A new page is started by a
-`p' command.  Positioning, writing, and drawing commands are always
-done within the current page, so they cannot occur before the first `p'
-command.  Absolute positioning (by the `H' and `V' commands) is done
-relative to the current page; all other positioning is done relative to
-the current location within this page.

-8.1.2.2 Simple Commands
-.......................
-
-The commands in this subsection have a command code consisting of a
-single character, taking a fixed number of arguments.  Most of them are
-commands for positioning and text writing.  These commands are smart
-about whitespace.  Optionally, syntactical space can be inserted
-before, after, and between the command letter and its arguments.  All
-of these commands are stackable, i.e., they can be preceded by other
-simple commands or followed by arbitrary other commands on the same
-line.  A separating syntactical space is only necessary when two
-integer arguments would clash or if the preceding argument ends with a
-string argument.
-
-`C XXX<whitespace>'
-     Print a special character named XXX.  The trailing syntactical
-     space or line break is necessary to allow glyph names of arbitrary
-     length.  The glyph is printed at the current print position; the
-     glyph's size is read from the font file.  The print position is
-     not changed.
-
-`c G'
-     Print glyph G at the current print position;(1) (*note Simple
-     Commands-Footnote-1::) the glyph's size is read from the font
-     file.  The print position is not changed.
-
-`f N'
-     Set font to font number N (a non-negative integer).
-
-`H N'
-     Move right to the absolute vertical position N (a non-negative
-     integer in basic units `u' relative to left edge of current page.
-
-`h N'
-     Move N (a non-negative integer) basic units `u' horizontally to
-     the right.  The original UNIX troff manual allows negative values
-     for N also, but `gtroff' doesn't use this.
-
-`m COLOR-SCHEME [COMPONENT ...]'
-     Set the color for text (glyphs), line drawing, and the outline of
-     graphic objects using different color schemes; the analoguous
-     command for the filling color of graphic objects is `DF'.  The
-     color components are specified as integer arguments between 0 and
-     65536.  The number of color components and their meaning vary for
-     the different color schemes.  These commands are generated by
-     `gtroff''s escape sequence `\m'.  No position changing.  These
-     commands are a `gtroff' extension.
-
-    `mc CYAN MAGENTA YELLOW'
-          Set color using the CMY color scheme, having the 3 color
-          components CYAN, MAGENTA, and YELLOW.
-
-    `md'
-          Set color to the default color value (black in most cases).
-          No component arguments.
-
-    `mg GRAY'
-          Set color to the shade of gray given by the argument, an
-          integer between 0 (black) and 65536 (white).
-
-    `mk CYAN MAGENTA YELLOW BLACK'
-          Set color using the CMYK color scheme, having the 4 color
-          components CYAN, MAGENTA, YELLOW, and BLACK.
-
-    `mr RED GREEN BLUE'
-          Set color using the RGB color scheme, having the 3 color
-          components RED, GREEN, and BLUE.
-
-`N N'
-     Print glyph with index N (a non-negative integer) of the current
-     font.  This command is a `gtroff' extension.
-
-`n B A'
-     Inform the device about a line break, but no positioning is done by
-     this command.  In AT&T `troff', the integer arguments B and A
-     informed about the space before and after the current line to make
-     the intermediate output more human readable without performing any
-     action.  In `groff', they are just ignored, but they must be
-     provided for compatibility reasons.
-
-`p N'
-     Begin a new page in the outprint.  The page number is set to N.
-     This page is completely independent of pages formerly processed
-     even if those have the same page number.  The vertical position on
-     the outprint is automatically set to 0.  All positioning, writing,
-     and drawing is always done relative to a page, so a `p' command
-     must be issued before any of these commands.
-
-`s N'
-     Set point size to N scaled points (this is unit `z').  AT&T
-     `troff' used the unit points (`p') instead.  *Note Output Language
-     Compatibility::.
-
-`t XXX<whitespace>'
-`t XXX DUMMY-ARG<whitespace>'
-     Print a word, i.e., a sequence of characters XXX representing
-     output glyphs which names are single characters, terminated by a
-     space character or a line break; an optional second integer
-     argument is ignored (this allows the formatter to generate an even
-     number of arguments).  The first glyph should be printed at the
-     current position, the current horizontal position should then be
-     increased by the width of the first glyph, and so on for each
-     glyph.  The widths of the glyphs are read from the font file,
-     scaled for the current point size, and rounded to a multiple of
-     the horizontal resolution.  Special characters cannot be printed
-     using this command (use the `C' command for special characters).
-     This command is a `gtroff' extension; it is only used for devices
-     whose `DESC' file contains the `tcommand' keyword (*note DESC File
-     Format::).
-
-`u N XXX<whitespace>'
-     Print word with track kerning.  This is the same as the `t'
-     command except that after printing each glyph, the current
-     horizontal position is increased by the sum of the width of that
-     glyph and N (an integer in basic units `u').  This command is a
-     `gtroff' extension; it is only used for devices whose `DESC' file
-     contains the `tcommand' keyword (*note DESC File Format::).
-
-`V N'
-     Move down to the absolute vertical position N (a non-negative
-     integer in basic units `u') relative to upper edge of current page.
-
-`v N'
-     Move N basic units `u' down (N is a non-negative integer).  The
-     original UNIX troff manual allows negative values for N also, but
-     `gtroff' doesn't use this.
-
-`w'
-     Informs about a paddable white space to increase readability.  The
-     spacing itself must be performed explicitly by a move command.

-8.1.2.3 Graphics Commands
-.........................
-
-Each graphics or drawing command in the intermediate output starts with
-the letter `D', followed by one or two characters that specify a
-subcommand; this is followed by a fixed or variable number of integer
-arguments that are separated by a single space character.  A `D'
-command may not be followed by another command on the same line (apart
-from a comment), so each `D' command is terminated by a syntactical
-line break.
-
-   `gtroff' output follows the classical spacing rules (no space
-between command and subcommand, all arguments are preceded by a single
-space character), but the parser allows optional space between the
-command letters and makes the space before the first argument optional.
-As usual, each space can be any sequence of tab and space characters.
-
-   Some graphics commands can take a variable number of arguments.  In
-this case, they are integers representing a size measured in basic
-units `u'.  The arguments called H1, H2, ..., HN stand for horizontal
-distances where positive means right, negative left.  The arguments
-called V1, V2, ..., VN stand for vertical distances where positive
-means down, negative up.  All these distances are offsets relative to
-the current location.
-
-   Each graphics command directly corresponds to a similar `gtroff'
-`\D' escape sequence.  *Note Drawing Requests::.
-
-   Unknown `D' commands are assumed to be device-specific.  Its
-arguments are parsed as strings; the whole information is then sent to
-the postprocessor.
-
-   In the following command reference, the syntax element <line
-break> means a syntactical line break as defined above.
-
-`D~ H1 V1 H2 V2 ... HN VN<line break>'
-     Draw B-spline from current position to offset (H1,V1), then to
-     offset (H2,V2), if given, etc. up to (HN,VN).  This command takes
-     a variable number of argument pairs; the current position is moved
-     to the terminal point of the drawn curve.
-
-`Da H1 V1 H2 V2<line break>'
-     Draw arc from current position to (H1,V1)+(H2,V2) with center at
-     (H1,V1); then move the current position to the final point of the
-     arc.
-
-`DC D<line break>'
-`DC D DUMMY-ARG<line break>'
-     Draw a solid circle using the current fill color with diameter D
-     (integer in basic units `u') with leftmost point at the current
-     position; then move the current position to the rightmost point of
-     the circle.  An optional second integer argument is ignored (this
-     allows the formatter to generate an even number of arguments).
-     This command is a `gtroff' extension.
-
-`Dc D<line break>'
-     Draw circle line with diameter D (integer in basic units `u') with
-     leftmost point at the current position; then move the current
-     position to the rightmost point of the circle.
-
-`DE H V<line break>'
-     Draw a solid ellipse in the current fill color with a horizontal
-     diameter of H and a vertical diameter of V (both integers in basic
-     units `u') with the leftmost point at the current position; then
-     move to the rightmost point of the ellipse.  This command is a
-     `gtroff' extension.
-
-`De H V<line break>'
-     Draw an outlined ellipse with a horizontal diameter of H and a
-     vertical diameter of V (both integers in basic units `u') with the
-     leftmost point at current position; then move to the rightmost
-     point of the ellipse.
-
-`DF COLOR-SCHEME [COMPONENT ...]<line break>'
-     Set fill color for solid drawing objects using different color
-     schemes; the analoguous command for setting the color of text, line
-     graphics, and the outline of graphic objects is `m'.  The color
-     components are specified as integer arguments between 0 and 65536.
-     The number of color components and their meaning vary for the
-     different color schemes.  These commands are generated by
-     `gtroff''s escape sequences `\D'F ...'' and `\M' (with no other
-     corresponding graphics commands).  No position changing.  This
-     command is a `gtroff' extension.
-
-    `DFc CYAN MAGENTA YELLOW<line break>'
-          Set fill color for solid drawing objects using the CMY color
-          scheme, having the 3 color components CYAN, MAGENTA, and
-          YELLOW.
-
-    `DFd<line break>'
-          Set fill color for solid drawing objects to the default fill
-          color value (black in most cases).  No component arguments.
-
-    `DFg GRAY<line break>'
-          Set fill color for solid drawing objects to the shade of gray
-          given by the argument, an integer between 0 (black) and 65536
-          (white).
-
-    `DFk CYAN MAGENTA YELLOW BLACK<line break>'
-          Set fill color for solid drawing objects using the CMYK color
-          scheme, having the 4 color components CYAN, MAGENTA, YELLOW,
-          and BLACK.
-
-    `DFr RED GREEN BLUE<line break>'
-          Set fill color for solid drawing objects using the RGB color
-          scheme, having the 3 color components RED, GREEN, and BLUE.
-
-`Df N<line break>'
-     The argument N must be an integer in the range -32767 to 32767.
-
-    0 <= N <= 1000
-          Set the color for filling solid drawing objects to a shade of
-          gray, where 0 corresponds to solid white, 1000 (the default)
-          to solid black, and values in between to intermediate shades
-          of gray; this is obsoleted by command `DFg'.
-
-    N < 0 or N > 1000
-          Set the filling color to the color that is currently being
-          used for the text and the outline, see command `m'.  For
-          example, the command sequence
-
-
-               mg 0 0 65536
-               Df -1
-
-          sets all colors to blue.
-
-     No position changing.  This command is a `gtroff' extension.
-
-`Dl H V<line break>'
-     Draw line from current position to offset (H,V) (integers in basic
-     units `u'); then set current position to the end of the drawn line.
-
-`Dp H1 V1 H2 V2 ... HN VN<line break>'
-     Draw a polygon line from current position to offset (H1,V1), from
-     there to offset (H2,V2), etc. up to offset (HN,VN), and from there
-     back to the starting position.  For historical reasons, the
-     position is changed by adding the sum of all arguments with odd
-     index to the actual horizontal position and the even ones to the
-     vertical position.  Although this doesn't make sense it is kept
-     for compatibility.  This command is a `gtroff' extension.
-
-`Dp H1 V1 H2 V2 ... HN VN<line break>'
-     Draw a solid polygon in the current fill color rather than an
-     outlined polygon, using the same arguments and positioning as the
-     corresponding `Dp' command.  This command is a `gtroff' extension.
-
-`Dt N<line break>'
-     Set the current line thickness to N (an integer in basic units
-     `u') if N>0; if N=0 select the smallest available line thickness;
-     if N<0 set the line thickness proportional to the point size (this
-     is the default before the first `Dt' command was specified).  For
-     historical reasons, the horizontal position is changed by adding
-     the argument to the actual horizontal position, while the vertical
-     position is not changed.  Although this doesn't make sense it is
-     kept for compatibility.  This command is a `gtroff' extension.

-8.1.2.4 Device Control Commands
-...............................
-
-Each device control command starts with the letter `x', followed by a
-space character (optional or arbitrary space or tab in `gtroff') and a
-subcommand letter or word; each argument (if any) must be preceded by a
-syntactical space.  All `x' commands are terminated by a syntactical
-line break; no device control command can be followed by another
-command on the same line (except a comment).
-
-   The subcommand is basically a single letter, but to increase
-readability, it can be written as a word, i.e., an arbitrary sequence
-of characters terminated by the next tab, space, or newline character.
-All characters of the subcommand word but the first are simply ignored.
-For example, `gtroff' outputs the initialization command `x i' as
-`x init' and the resolution command `x r' as `x res'.
-
-   In the following, the syntax element <line break> means a
-syntactical line break (*note Separation::).
-
-`xF NAME<line break>'
-     The `F' stands for FILENAME.
-
-     Use NAME as the intended name for the current file in error
-     reports.  This is useful for remembering the original file name
-     when `gtroff' uses an internal piping mechanism.  The input file is
-     not changed by this command.  This command is a `gtroff' extension.
-
-`xf N S<line break>'
-     The `f' stands for FONT.
-
-     Mount font position N (a non-negative integer) with font named S
-     (a text word).  *Note Font Positions::.
-
-`xH N<line break>'
-     The `H' stands for HEIGHT.
-
-     Set glyph height to N (a positive integer in scaled points `z').
-     AT&T `troff' uses the unit points (`p') instead.  *Note Output
-     Language Compatibility::.
-
-`xi<line break>'
-     The `i' stands for INIT.
-
-     Initialize device.  This is the third command of the prologue.
-
-`xp<line break>'
-     The `p' stands for PAUSE.
-
-     Parsed but ignored.  The original UNIX troff manual writes
-
-          pause device, can be restarted
-
-`xr N H V<line break>'
-     The `r' stands for RESOLUTION.
-
-     Resolution is N, while H is the minimal horizontal motion, and V
-     the minimal vertical motion possible with this device; all
-     arguments are positive integers in basic units `u' per inch.  This
-     is the second command of the prologue.
-
-`xS N<line break>'
-     The `S' stands for SLANT.
-
-     Set slant to N (an integer in basic units `u').
-
-`xs<line break>'
-     The `s' stands for STOP.
-
-     Terminates the processing of the current file; issued as the last
-     command of any intermediate troff output.
-
-`xt<line break>'
-     The `t' stands for TRAILER.
-
-     Generate trailer information, if any.  In GTROFF, this is actually
-     just ignored.
-
-`xT XXX<line break>'
-     The `T' stands for TYPESETTER.
-
-     Set name of device to word XXX, a sequence of characters ended by
-     the next white space character.  The possible device names coincide
-     with those from the `groff' `-T' option.  This is the first
-     command of the prologue.
-
-`xu N<line break>'
-     The `u' stands for UNDERLINE.
-
-     Configure underlining of spaces.  If N is 1, start underlining of
-     spaces; if N is 0, stop underlining of spaces.  This is needed for
-     the `cu' request in nroff mode and is ignored otherwise.  This
-     command is a `gtroff' extension.
-
-`xX ANYTHING<line break>'
-     The `x' stands for X-ESCAPE.
-
-     Send string ANYTHING uninterpreted to the device.  If the line
-     following this command starts with a `+' character this line is
-     interpreted as a continuation line in the following sense.  The
-     `+' is ignored, but a newline character is sent instead to the
-     device, the rest of the line is sent uninterpreted.  The same
-     applies to all following lines until the first character of a line
-     is not a `+' character.  This command is generated by the `gtroff'
-     escape sequence `\X'.  The line-continuing feature is a `gtroff'
-     extension.

-8.1.2.5 Obsolete Command
-........................
-
-In AT&T `troff' output, the writing of a single glyph is mostly done by
-a very strange command that combines a horizontal move and a single
-character giving the glyph name.  It doesn't have a command code, but
-is represented by a 3-character argument consisting of exactly 2 digits
-and a character.
-
-DDG
-     Move right DD (exactly two decimal digits) basic units `u', then
-     print glyph G (represented as a single character).
-
-     In `gtroff', arbitrary syntactical space around and within this
-     command is allowed to be added.  Only when a preceding command on
-     the same line ends with an argument of variable length a
-     separating space is obligatory.  In AT&T `troff', large clusters
-     of these and other commands are used, mostly without spaces; this
-     made such output almost unreadable.
-
-   For modern high-resolution devices, this command does not make sense
-because the width of the glyphs can become much larger than two decimal
-digits.  In `gtroff', this is only used for the devices `X75',
-`X75-12', `X100', and `X100-12'.  For other devices, the commands `t'
-and `u' provide a better functionality.

-8.1.3 Intermediate Output Examples
-----------------------------------
-
-This section presents the intermediate output generated from the same
-input for three different devices.  The input is the sentence `hell
-world' fed into `gtroff' on the command line.
-
-High-resolution device `ps'
-     This is the standard output of `gtroff' if no `-T' option is given.
-
-          shell> echo "hell world" | groff -Z -T ps
-
-          x T ps
-          x res 72000 1 1
-          x init
-          p1
-          x font 5 TR
-          f5
-          s10000
-          V12000
-          H72000
-          thell
-          wh2500
-          tw
-          H96620
-          torld
-          n12000 0
-          x trailer
-          V792000
-          x stop
-
-     This output can be fed into `grops' to get its representation as a
-     PostScript file.
-
-Low-resolution device `latin1'
-     This is similar to the high-resolution device except that the
-     positioning is done at a minor scale.  Some comments (lines
-     starting with `#') were added for clarification; they were not
-     generated by the formatter.
-
-          shell> echo "hell world" | groff -Z -T latin1
-
-          # prologue
-          x T latin1
-          x res 240 24 40
-          x init
-          # begin a new page
-          p1
-          # font setup
-          x font 1 R
-          f1
-          s10
-          # initial positioning on the page
-          V40
-          H0
-          # write text `hell'
-          thell
-          # inform about space, and issue a horizontal jump
-          wh24
-          # write text `world'
-          tworld
-          # announce line break, but do nothing because ...
-          n40 0
-          # ... the end of the document has been reached
-          x trailer
-          V2640
-          x stop
-
-     This output can be fed into `grotty' to get a formatted text
-     document.
-
-AT&T `troff' output
-     Since a computer monitor has a very low resolution compared to
-     modern printers the intermediate output for the X Window devices
-     can use the jump-and-write command with its 2-digit displacements.
-
-          shell> echo "hell world" | groff -Z -T X100
-
-          x T X100
-          x res 100 1 1
-          x init
-          p1
-          x font 5 TR
-          f5
-          s10
-          V16
-          H100
-          # write text with jump-and-write commands
-          ch07e07l03lw06w11o07r05l03dh7
-          n16 0
-          x trailer
-          V1100
-          x stop
-
-     This output can be fed into `xditview' or `gxditview' for
-     displaying in X.
-
-     Due to the obsolete jump-and-write command, the text clusters in
-     the AT&T `troff' output are almost unreadable.

-
-8.1.4 Output Language Compatibility
------------------------------------
-
-The intermediate output language of AT&T `troff' was first documented
-in the UNIX troff manual, with later additions documented in `A
-Typesetter-indenpendent TROFF', written by Brian Kernighan.
-
-   The `gtroff' intermediate output format is compatible with this
-specification except for the following features.
-
-   * The classical quasi device independence is not yet implemented.
-
-   * The old hardware was very different from what we use today.  So the
-     `groff' devices are also fundamentally different from the ones in
-     AT&T `troff'.  For example, the AT&T PostScript device is called
-     `post' and has a resolution of only 720 units per inch, suitable
-     for printers 20 years ago, while `groff''s `ps' device has a
-     resolution of 72000 units per inch.  Maybe, by implementing some
-     rescaling mechanism similar to the classical quasi device
-     independence, `groff' could emulate AT&T's `post' device.
-
-   * The B-spline command `D~' is correctly handled by the intermediate
-     output parser, but the drawing routines aren't implemented in some
-     of the postprocessor programs.
-
-   * The argument of the commands `s' and `x H' has the implicit unit
-     scaled point `z' in `gtroff', while AT&T `troff' has point (`p').
-     This isn't an incompatibility but a compatible extension, for both
-     units coincide for all devices without a `sizescale' parameter in
-     the `DESC' file, including all postprocessors from AT&T and
-     `groff''s text devices.  The few `groff' devices with a
-     `sizescale' parameter either do not exist for AT&T `troff', have a
-     different name, or seem to have a different resolution.  So
-     conflicts are very unlikely.
-
-   * The position changing after the commands `Dp', `DP', and `Dt' is
-     illogical, but as old versions of `gtroff' used this feature it is
-     kept for compatibility reasons.

-8.2 Font Files
-==============
-
-The `gtroff' font format is roughly a superset of the `ditroff' font
-format (as used in later versions of AT&T `troff' and its descendants).
-Unlike the `ditroff' font format, there is no associated binary
-format; all files are text files.(1) (*note Font Files-Footnote-1::)
-The font files for device NAME are stored in a directory `devNAME'.
-There are two types of file: a device description file called `DESC'
-and for each font F a font file called `F'.

-
-
-File: groff,  Node: DESC File Format,  Next: Font File Format,  Prev: Font Files,  Up: Font Files
-
-8.2.1 `DESC' File Format
-------------------------
-
-The `DESC' file can contain the following types of line.  Except for
-the `charset' keyword which must comes last (if at all), the order of
-the lines is not important.
-
-`res N'
-     There are N machine units per inch.
-
-`hor N'
-     The horizontal resolution is N machine units.  All horizontal
-     quantities are rounded to be multiples of this value.
-
-`vert N'
-     The vertical resolution is N machine units.  All vertical
-     quantities are rounded to be multiples of this value.
-
-`sizescale N'
-     The scale factor for point sizes.  By default this has a value
-     of 1.  One scaled point is equal to one point/N.  The arguments to
-     the `unitwidth' and `sizes' commands are given in scaled points.
-     *Note Fractional Type Sizes::, for more information.
-
-`unitwidth N'
-     Quantities in the font files are given in machine units for fonts
-     whose point size is N scaled points.
-
-`prepro PROGRAM'
-     Call PROGRAM as a preprocessor.  Currently, this keyword is used
-     by `groff' with option `-Thtml' only.
-
-`postpro PROGRAM'
-     Call PROGRAM as a postprocessor.  For example, the line
-
-
-          postpro grodvi
-
-     in the file `devdvi/DESC' makes `groff' call `grodvi' if option
-     `-Tdvi' is given (and `-Z' isn't used).
-
-`tcommand'
-     This means that the postprocessor can handle the `t' and `u'
-     intermediate output commands.
-
-`sizes S1 S2 ... SN 0'
-     This means that the device has fonts at S1, S2, ...  SN scaled
-     points.  The list of sizes must be terminated by 0 (this is digit
-     zero).  Each SI can also be a range of sizes M-N.  The list can
-     extend over more than one line.
-
-`styles S1 S2 ... SM'
-     The first M font positions are associated with styles S1 ... SM.
-
-`fonts N F1 F2 F3 ... FN'
-     Fonts F1 ... FN are mounted in the font positions M+1, ..., M+N
-     where M is the number of styles.  This command may extend over
-     more than one line.  A font name of 0 means no font is mounted on
-     the corresponding font position.
-
-`family FAM'
-     The default font family is FAM.
-
-`use_charnames_in_special'
-     This command indicates that `gtroff' should encode special
-     characters inside special commands.  Currently, this is only used
-     by the HTML output device.  *Note Postprocessor Access::.
-
-`papersize STRING ...'
-     Select a paper size.  Valid values for STRING are the ISO paper
-     types `A0'-`A7', `B0'-`B7', `C0'-`C7', `D0'-`D7', `DL', and the US
-     paper types `letter', `legal', `tabloid', `ledger', `statement',
-     `executive', `com10', and `monarch'.  Case is not significant for
-     STRING if it holds predefined paper types.  Alternatively, STRING
-     can be a file name (e.g. `/etc/papersize'); if the file can be
-     opened, `groff' reads the first line and tests for the above paper
-     sizes.  Finally, STRING can be a custom paper size in the format
-     `LENGTH,WIDTH' (no spaces before and after the comma).  Both
-     LENGTH and WIDTH must have a unit appended; valid values are `i'
-     for inches, `C' for centimeters, `p' for points, and `P' for
-     picas.  Example: `12c,235p'.  An argument which starts with a
-     digit is always treated as a custom paper format.  `papersize'
-     sets both the vertical and horizontal dimension of the output
-     medium.
-
-     More than one argument can be specified; `groff' scans from left to
-     right and uses the first valid paper specification.
-
-`pass_filenames'
-     Tell `gtroff' to emit the name of the source file currently being
-     processed.  This is achieved by the intermediate output command
-     `F'.  Currently, this is only used by the HTML output device.
-
-`print PROGRAM'
-     Use PROGRAM as a spooler program for printing.  If omitted, the
-     `-l' and `-L' options of `groff' are ignored.
-
-`charset'
-     This line and everything following in the file are ignored.  It is
-     allowed for the sake of backwards compatibility.
-
-   The `res', `unitwidth', `fonts', and `sizes' lines are mandatory.
-Other commands are ignored by `gtroff' but may be used by
-postprocessors to store arbitrary information about the device in the
-`DESC' file.
-
-   Here a list of obsolete keywords which are recognized by `groff' but
-completely ignored: `spare1', `spare2', `biggestfont'.

-
-8.2.2 Font File Format
-----------------------
-
-A "font file", also (and probably better) called a "font description
-file", has two sections.  The first section is a sequence of lines each
-containing a sequence of blank delimited words; the first word in the
-line is a key, and subsequent words give a value for that key.
-
-`name F'
-     The name of the font is F.
-
-`spacewidth N'
-     The normal width of a space is N.
-
-`slant N'
-     The glyphs of the font have a slant of N degrees.  (Positive means
-     forward.)
-
-`ligatures LIG1 LIG2 ... LIGN [0]'
-     Glyphs LIG1, LIG2, ..., LIGN are ligatures; possible ligatures are
-     `ff', `fi', `fl', `ffi' and `ffl'.  For backwards compatibility,
-     the list of ligatures may be terminated with a 0.  The list of
-     ligatures may not extend over more than one line.
-
-`special'
-     The font is "special"; this means that when a glyph is requested
-     that is not present in the current font, it is searched for in any
-     special fonts that are mounted.
-
-   Other commands are ignored by `gtroff' but may be used by
-postprocessors to store arbitrary information about the font in the font
-file.
-
-   The first section can contain comments which start with the `#'
-character and extend to the end of a line.
-
-   The second section contains one or two subsections.  It must contain
-a `charset' subsection and it may also contain a `kernpairs'
-subsection.  These subsections can appear in any order.  Each
-subsection starts with a word on a line by itself.
-
-   The word `charset' starts the character set subsection.(1) (*note
-Font File Format-Footnote-1::)  The `charset' line is followed by a
-sequence of lines.  Each line gives information for one glyph.  A line
-comprises a number of fields separated by blanks or tabs.  The format is
-
-     NAME METRICS TYPE CODE [ENTITY-NAME] [`--' COMMENT]
-
-NAME identifies the glyph name(2) (*note Font File Format-Footnote-2::):
-If NAME is a single character C then it corresponds to the `gtroff'
-input character C; if it is of the form `\C' where C is a single
-character, then it corresponds to the special character `\[C]';
-otherwise it corresponds to the special character `\[NAME]'.  If it is
-exactly two characters XX it can be entered as `\(XX'.  Note that
-single-letter special characters can't be accessed as `\C'; the only
-exception is `\-' which is identical to `\[-]'.
-
-   `gtroff' supports 8-bit input characters; however some utilities
-have difficulties with eight-bit characters.  For this reason, there is
-a convention that the entity name `charN' is equivalent to the single
-input character whose code is N.  For example, `char163' would be
-equivalent to the character with code 163 which is the pounds sterling
-sign in the ISO Latin-1 character set.  You shouldn't use `charN'
-entities in font description files since they are related to input, not
-output.  Otherwise, you get hard-coded connections between input and
-output encoding which prevents use of different (input) character sets.
-
-   The name `---' is special and indicates that the glyph is unnamed;
-such glyphs can only be used by means of the `\N' escape sequence in
-`gtroff'.
-
-   The TYPE field gives the glyph type:
-
-`1'
-     the glyph has a descender, for example, `p';
-
-`2'
-     the glyph has an ascender, for example, `b';
-
-`3'
-     the glyph has both an ascender and a descender, for example, `('.
-
-   The CODE field gives the code which the postprocessor uses to print
-the glyph.  The glyph can also be input to `gtroff' using this code by
-means of the `\N' escape sequence.  CODE can be any integer.  If it
-starts with `0' it is interpreted as octal; if it starts with `0x' or
-`0X' it is interpreted as hexadecimal.  Note, however, that the `\N'
-escape sequence only accepts a decimal integer.
-
-   The ENTITY-NAME field gives an ASCII string identifying the glyph
-which the postprocessor uses to print the `gtroff' glyph NAME.  This
-field is optional and has been introduced so that the HTML device
-driver can encode its character set.  For example, the glyph `\[Po]' is
-represented as `&pound;' in HTML 4.0.
-
-   Anything on the line after the ENTITY-NAME field resp. after `--'
-will be ignored.
-
-   The METRICS field has the form:

-
-There must not be any spaces between these subfields (it has been split
-here into two lines for better legibility only).  Missing subfields are
-assumed to be 0.  The subfields are all decimal integers.  Since there
-is no associated binary format, these values are not required to fit
-into a variable of type `char' as they are in `ditroff'.  The WIDTH
-subfield gives the width of the glyph.  The HEIGHT subfield gives the
-height of the glyph (upwards is positive); if a glyph does not extend
-above the baseline, it should be given a zero height, rather than a
-negative height.  The DEPTH subfield gives the depth of the glyph, that
-is, the distance from the baseline to the lowest point below the
-baseline to which the glyph extends (downwards is positive); if a glyph
-does not extend below the baseline, it should be given a zero depth,
-rather than a negative depth.  The ITALIC-CORRECTION subfield gives the
-amount of space that should be added after the glyph when it is
-immediately to be followed by a glyph from a roman font.  The
-LEFT-ITALIC-CORRECTION subfield gives the amount of space that should
-be added before the glyph when it is immediately to be preceded by a
-glyph from a roman font.  The SUBSCRIPT-CORRECTION gives the amount of
-space that should be added after a glyph before adding a subscript.
-This should be less than the italic correction.
-
-   A line in the `charset' section can also have the format
-
-
-     NAME "

-This indicates that NAME is just another name for the glyph mentioned
-in the preceding line.
-
-   The word `kernpairs' starts the kernpairs section.  This contains a
-sequence of lines of the form:
-
-
-     C1 C2 N
-
-This means that when glyph C1 appears next to glyph C2 the space
-between them should be increased by N.  Most entries in the kernpairs
-section have a negative value for N.

-   (1) This keyword is misnamed since it starts a list of ordered
-glyphs, not characters.
-
-   (2) The distinction between input, characters, and output, glyphs,
-is not clearly separated in the terminology of `groff'; for example,
-the `char' request should be called `glyph' since it defines an output
-entity.

-A.1 GNU Free Documentation License
-==================================
-
-                      Version 1.2, November 2002
-
-     Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.
-     51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA
-
-     Everyone is permitted to copy and distribute verbatim copies
-     of this license document, but changing it is not allowed.
-
-  0. PREAMBLE
-
-     The purpose of this License is to make a manual, textbook, or other
-     functional and useful document "free" in the sense of freedom: to
-     assure everyone the effective freedom to copy and redistribute it,
-     with or without modifying it, either commercially or
-     noncommercially.  Secondarily, this License preserves for the
-     author and publisher a way to get credit for their work, while not
-     being considered responsible for modifications made by others.
-
-     This License is a kind of "copyleft", which means that derivative
-     works of the document must themselves be free in the same sense.
-     It complements the GNU General Public License, which is a copyleft
-     license designed for free software.
-
-     We have designed this License in order to use it for manuals for
-     free software, because free software needs free documentation: a
-     free program should come with manuals providing the same freedoms
-     that the software does.  But this License is not limited to
-     software manuals; it can be used for any textual work, regardless
-     of subject matter or whether it is published as a printed book.
-     We recommend this License principally for works whose purpose is
-     instruction or reference.
-
-  1. APPLICABILITY AND DEFINITIONS
-
-     This License applies to any manual or other work, in any medium,
-     that contains a notice placed by the copyright holder saying it
-     can be distributed under the terms of this License.  Such a notice
-     grants a world-wide, royalty-free license, unlimited in duration,
-     to use that work under the conditions stated herein.  The
-     "Document", below, refers to any such manual or work.  Any member
-     of the public is a licensee, and is addressed as "you".  You
-     accept the license if you copy, modify or distribute the work in a
-     way requiring permission under copyright law.
-
-     A "Modified Version" of the Document means any work containing the
-     Document or a portion of it, either copied verbatim, or with
-     modifications and/or translated into another language.
-
-     A "Secondary Section" is a named appendix or a front-matter section
-     of the Document that deals exclusively with the relationship of the
-     publishers or authors of the Document to the Document's overall
-     subject (or to related matters) and contains nothing that could
-     fall directly within that overall subject.  (Thus, if the Document
-     is in part a textbook of mathematics, a Secondary Section may not
-     explain any mathematics.)  The relationship could be a matter of
-     historical connection with the subject or with related matters, or
-     of legal, commercial, philosophical, ethical or political position
-     regarding them.
-
-     The "Invariant Sections" are certain Secondary Sections whose
-     titles are designated, as being those of Invariant Sections, in
-     the notice that says that the Document is released under this
-     License.  If a section does not fit the above definition of
-     Secondary then it is not allowed to be designated as Invariant.
-     The Document may contain zero Invariant Sections.  If the Document
-     does not identify any Invariant Sections then there are none.
-
-     The "Cover Texts" are certain short passages of text that are
-     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
-     that says that the Document is released under this License.  A
-     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
-     be at most 25 words.
-
-     A "Transparent" copy of the Document means a machine-readable copy,
-     represented in a format whose specification is available to the
-     general public, that is suitable for revising the document
-     straightforwardly with generic text editors or (for images
-     composed of pixels) generic paint programs or (for drawings) some
-     widely available drawing editor, and that is suitable for input to
-     text formatters or for automatic translation to a variety of
-     formats suitable for input to text formatters.  A copy made in an
-     otherwise Transparent file format whose markup, or absence of
-     markup, has been arranged to thwart or discourage subsequent
-     modification by readers is not Transparent.  An image format is
-     not Transparent if used for any substantial amount of text.  A
-     copy that is not "Transparent" is called "Opaque".
-
-     Examples of suitable formats for Transparent copies include plain
-     ASCII without markup, Texinfo input format, LaTeX input format,
-     SGML or XML using a publicly available DTD, and
-     standard-conforming simple HTML, PostScript or PDF designed for
-     human modification.  Examples of transparent image formats include
-     PNG, XCF and JPG.  Opaque formats include proprietary formats that
-     can be read and edited only by proprietary word processors, SGML or
-     XML for which the DTD and/or processing tools are not generally
-     available, and the machine-generated HTML, PostScript or PDF
-     produced by some word processors for output purposes only.
-
-     The "Title Page" means, for a printed book, the title page itself,
-     plus such following pages as are needed to hold, legibly, the
-     material this License requires to appear in the title page.  For
-     works in formats which do not have any title page as such, "Title
-     Page" means the text near the most prominent appearance of the
-     work's title, preceding the beginning of the body of the text.
-
-     A section "Entitled XYZ" means a named subunit of the Document
-     whose title either is precisely XYZ or contains XYZ in parentheses
-     following text that translates XYZ in another language.  (Here XYZ
-     stands for a specific section name mentioned below, such as
-     "Acknowledgements", "Dedications", "Endorsements", or "History".)
-     To "Preserve the Title" of such a section when you modify the
-     Document means that it remains a section "Entitled XYZ" according
-     to this definition.
-
-     The Document may include Warranty Disclaimers next to the notice
-     which states that this License applies to the Document.  These
-     Warranty Disclaimers are considered to be included by reference in
-     this License, but only as regards disclaiming warranties: any other
-     implication that these Warranty Disclaimers may have is void and
-     has no effect on the meaning of this License.
-
-  2. VERBATIM COPYING
-
-     You may copy and distribute the Document in any medium, either
-     commercially or noncommercially, provided that this License, the
-     copyright notices, and the license notice saying this License
-     applies to the Document are reproduced in all copies, and that you
-     add no other conditions whatsoever to those of this License.  You
-     may not use technical measures to obstruct or control the reading
-     or further copying of the copies you make or distribute.  However,
-     you may accept compensation in exchange for copies.  If you
-     distribute a large enough number of copies you must also follow
-     the conditions in section 3.
-
-     You may also lend copies, under the same conditions stated above,
-     and you may publicly display copies.
-
-  3. COPYING IN QUANTITY
-
-     If you publish printed copies (or copies in media that commonly
-     have printed covers) of the Document, numbering more than 100, and
-     the Document's license notice requires Cover Texts, you must
-     enclose the copies in covers that carry, clearly and legibly, all
-     these Cover Texts: Front-Cover Texts on the front cover, and
-     Back-Cover Texts on the back cover.  Both covers must also clearly
-     and legibly identify you as the publisher of these copies.  The
-     front cover must present the full title with all words of the
-     title equally prominent and visible.  You may add other material
-     on the covers in addition.  Copying with changes limited to the
-     covers, as long as they preserve the title of the Document and
-     satisfy these conditions, can be treated as verbatim copying in
-     other respects.
-
-     If the required texts for either cover are too voluminous to fit
-     legibly, you should put the first ones listed (as many as fit
-     reasonably) on the actual cover, and continue the rest onto
-     adjacent pages.
-
-     If you publish or distribute Opaque copies of the Document
-     numbering more than 100, you must either include a
-     machine-readable Transparent copy along with each Opaque copy, or
-     state in or with each Opaque copy a computer-network location from
-     which the general network-using public has access to download
-     using public-standard network protocols a complete Transparent
-     copy of the Document, free of added material.  If you use the
-     latter option, you must take reasonably prudent steps, when you
-     begin distribution of Opaque copies in quantity, to ensure that
-     this Transparent copy will remain thus accessible at the stated
-     location until at least one year after the last time you
-     distribute an Opaque copy (directly or through your agents or
-     retailers) of that edition to the public.
-
-     It is requested, but not required, that you contact the authors of
-     the Document well before redistributing any large number of
-     copies, to give them a chance to provide you with an updated
-     version of the Document.
-
-  4. MODIFICATIONS
-
-     You may copy and distribute a Modified Version of the Document
-     under the conditions of sections 2 and 3 above, provided that you
-     release the Modified Version under precisely this License, with
-     the Modified Version filling the role of the Document, thus
-     licensing distribution and modification of the Modified Version to
-     whoever possesses a copy of it.  In addition, you must do these
-     things in the Modified Version:
-
-       A. Use in the Title Page (and on the covers, if any) a title
-          distinct from that of the Document, and from those of
-          previous versions (which should, if there were any, be listed
-          in the History section of the Document).  You may use the
-          same title as a previous version if the original publisher of
-          that version gives permission.
-
-       B. List on the Title Page, as authors, one or more persons or
-          entities responsible for authorship of the modifications in
-          the Modified Version, together with at least five of the
-          principal authors of the Document (all of its principal
-          authors, if it has fewer than five), unless they release you
-          from this requirement.
-
-       C. State on the Title page the name of the publisher of the
-          Modified Version, as the publisher.
-
-       D. Preserve all the copyright notices of the Document.
-
-       E. Add an appropriate copyright notice for your modifications
-          adjacent to the other copyright notices.
-
-       F. Include, immediately after the copyright notices, a license
-          notice giving the public permission to use the Modified
-          Version under the terms of this License, in the form shown in
-          the Addendum below.
-
-       G. Preserve in that license notice the full lists of Invariant
-          Sections and required Cover Texts given in the Document's
-          license notice.
-
-       H. Include an unaltered copy of this License.
-
-       I. Preserve the section Entitled "History", Preserve its Title,
-          and add to it an item stating at least the title, year, new
-          authors, and publisher of the Modified Version as given on
-          the Title Page.  If there is no section Entitled "History" in
-          the Document, create one stating the title, year, authors,
-          and publisher of the Document as given on its Title Page,
-          then add an item describing the Modified Version as stated in
-          the previous sentence.
-
-       J. Preserve the network location, if any, given in the Document
-          for public access to a Transparent copy of the Document, and
-          likewise the network locations given in the Document for
-          previous versions it was based on.  These may be placed in
-          the "History" section.  You may omit a network location for a
-          work that was published at least four years before the
-          Document itself, or if the original publisher of the version
-          it refers to gives permission.
-
-       K. For any section Entitled "Acknowledgements" or "Dedications",
-          Preserve the Title of the section, and preserve in the
-          section all the substance and tone of each of the contributor
-          acknowledgements and/or dedications given therein.
-
-       L. Preserve all the Invariant Sections of the Document,
-          unaltered in their text and in their titles.  Section numbers
-          or the equivalent are not considered part of the section
-          titles.
-
-       M. Delete any section Entitled "Endorsements".  Such a section
-          may not be included in the Modified Version.
-
-       N. Do not retitle any existing section to be Entitled
-          "Endorsements" or to conflict in title with any Invariant
-          Section.
-
-       O. Preserve any Warranty Disclaimers.
-
-     If the Modified Version includes new front-matter sections or
-     appendices that qualify as Secondary Sections and contain no
-     material copied from the Document, you may at your option
-     designate some or all of these sections as invariant.  To do this,
-     add their titles to the list of Invariant Sections in the Modified
-     Version's license notice.  These titles must be distinct from any
-     other section titles.
-
-     You may add a section Entitled "Endorsements", provided it contains
-     nothing but endorsements of your Modified Version by various
-     parties--for example, statements of peer review or that the text
-     has been approved by an organization as the authoritative
-     definition of a standard.
-
-     You may add a passage of up to five words as a Front-Cover Text,
-     and a passage of up to 25 words as a Back-Cover Text, to the end
-     of the list of Cover Texts in the Modified Version.  Only one
-     passage of Front-Cover Text and one of Back-Cover Text may be
-     added by (or through arrangements made by) any one entity.  If the
-     Document already includes a cover text for the same cover,
-     previously added by you or by arrangement made by the same entity
-     you are acting on behalf of, you may not add another; but you may
-     replace the old one, on explicit permission from the previous
-     publisher that added the old one.
-
-     The author(s) and publisher(s) of the Document do not by this
-     License give permission to use their names for publicity for or to
-     assert or imply endorsement of any Modified Version.
-
-  5. COMBINING DOCUMENTS
-
-     You may combine the Document with other documents released under
-     this License, under the terms defined in section 4 above for
-     modified versions, provided that you include in the combination
-     all of the Invariant Sections of all of the original documents,
-     unmodified, and list them all as Invariant Sections of your
-     combined work in its license notice, and that you preserve all
-     their Warranty Disclaimers.
-
-     The combined work need only contain one copy of this License, and
-     multiple identical Invariant Sections may be replaced with a single
-     copy.  If there are multiple Invariant Sections with the same name
-     but different contents, make the title of each such section unique
-     by adding at the end of it, in parentheses, the name of the
-     original author or publisher of that section if known, or else a
-     unique number.  Make the same adjustment to the section titles in
-     the list of Invariant Sections in the license notice of the
-     combined work.
-
-     In the combination, you must combine any sections Entitled
-     "History" in the various original documents, forming one section
-     Entitled "History"; likewise combine any sections Entitled
-     "Acknowledgements", and any sections Entitled "Dedications".  You
-     must delete all sections Entitled "Endorsements."
-
-  6. COLLECTIONS OF DOCUMENTS
-
-     You may make a collection consisting of the Document and other
-     documents released under this License, and replace the individual
-     copies of this License in the various documents with a single copy
-     that is included in the collection, provided that you follow the
-     rules of this License for verbatim copying of each of the
-     documents in all other respects.
-
-     You may extract a single document from such a collection, and
-     distribute it individually under this License, provided you insert
-     a copy of this License into the extracted document, and follow
-     this License in all other respects regarding verbatim copying of
-     that document.
-
-  7. AGGREGATION WITH INDEPENDENT WORKS
-
-     A compilation of the Document or its derivatives with other
-     separate and independent documents or works, in or on a volume of
-     a storage or distribution medium, is called an "aggregate" if the
-     copyright resulting from the compilation is not used to limit the
-     legal rights of the compilation's users beyond what the individual
-     works permit.  When the Document is included in an aggregate, this
-     License does not apply to the other works in the aggregate which
-     are not themselves derivative works of the Document.
-
-     If the Cover Text requirement of section 3 is applicable to these
-     copies of the Document, then if the Document is less than one half
-     of the entire aggregate, the Document's Cover Texts may be placed
-     on covers that bracket the Document within the aggregate, or the
-     electronic equivalent of covers if the Document is in electronic
-     form.  Otherwise they must appear on printed covers that bracket
-     the whole aggregate.
-
-  8. TRANSLATION
-
-     Translation is considered a kind of modification, so you may
-     distribute translations of the Document under the terms of section
-     4.  Replacing Invariant Sections with translations requires special
-     permission from their copyright holders, but you may include
-     translations of some or all Invariant Sections in addition to the
-     original versions of these Invariant Sections.  You may include a
-     translation of this License, and all the license notices in the
-     Document, and any Warranty Disclaimers, provided that you also
-     include the original English version of this License and the
-     original versions of those notices and disclaimers.  In case of a
-     disagreement between the translation and the original version of
-     this License or a notice or disclaimer, the original version will
-     prevail.
-
-     If a section in the Document is Entitled "Acknowledgements",
-     "Dedications", or "History", the requirement (section 4) to
-     Preserve its Title (section 1) will typically require changing the
-     actual title.
-
-  9. TERMINATION
-
-     You may not copy, modify, sublicense, or distribute the Document
-     except as expressly provided for under this License.  Any other
-     attempt to copy, modify, sublicense or distribute the Document is
-     void, and will automatically terminate your rights under this
-     License.  However, parties who have received copies, or rights,
-     from you under this License will not have their licenses
-     terminated so long as such parties remain in full compliance.
-
- 10. FUTURE REVISIONS OF THIS LICENSE
-
-     The Free Software Foundation may publish new, revised versions of
-     the GNU Free Documentation License from time to time.  Such new
-     versions will be similar in spirit to the present version, but may
-     differ in detail to address new problems or concerns.  See
-     `http://www.gnu.org/copyleft/'.
-
-     Each version of the License is given a distinguishing version
-     number.  If the Document specifies that a particular numbered
-     version of this License "or any later version" applies to it, you
-     have the option of following the terms and conditions either of
-     that specified version or of any later version that has been
-     published (not as a draft) by the Free Software Foundation.  If
-     the Document does not specify a version number of this License,
-     you may choose any version ever published (not as a draft) by the
-     Free Software Foundation.
-
-A.1.1 ADDENDUM: How to use this License for your documents
-----------------------------------------------------------
-
-To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and license
-notices just after the title page:
-
-       Copyright (C)  YEAR  YOUR NAME.
-       Permission is granted to copy, distribute and/or modify this document
-       under the terms of the GNU Free Documentation License, Version 1.2
-       or any later version published by the Free Software Foundation;
-       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
-       Texts.  A copy of the license is included in the section entitled ``GNU
-       Free Documentation License''.
-
-   If you have Invariant Sections, Front-Cover Texts and Back-Cover
-Texts, replace the "with...Texts." line with this:
-
-         with the Invariant Sections being LIST THEIR TITLES, with
-         the Front-Cover Texts being LIST, and with the Back-Cover Texts
-         being LIST.
-
-   If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-
-   If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License, to
-permit their use in free software.

-@c To assure correct HTML translation, some ugly hacks are necessary.
-@c While processing a @def... request, the HTML translator looks at the
-@c next line to decide whether it should start indentation or not.  If
-@c it is something starting with @def... (e.g. @deffnx), it doesn't.
-@c So we must assure during macro expansion that a @def... is seen.
-@c
-@c The following macros have to be used:
-@c
-@c One item:
-@c
-@c   @Def...
-@c
-@c Two items:
-@c
-@c   @Def...List
-@c   @Def...ListEnd
-@c
-@c More than two:
-@c
-@c   @Def...List
-@c   @Def...Item
-@c   @Def...Item
-@c   ...
-@c   @Def...ListEnd
-@c
-@c The definition block must end with
-@c
-@c   @endDef...
-@c
-@c The above is valid for texinfo 4.0f and above.

-@c . @{ and @} fail with info if used in a macro.

-GNU @code{troff} (or @code{groff}) is a system for typesetting
-documents.  @code{troff} is very flexible and has been in existence (and
-use) for about 3@tie{}decades.  It is quite widespread and firmly
-entrenched in the @acronym{UNIX} community.

-@cindex @code{groff} -- what is it?
-
-@code{groff} belongs to an older generation of document preparation
-systems, which operate more like compilers than the more recent
-interactive @acronym{WYSIWYG}@footnote{What You See Is What You Get}
-systems.  @code{groff} and its contemporary counterpart, @TeX{}, both
-work using a @dfn{batch} paradigm: The input (or @dfn{source}) files are
-normal text files with embedded formatting commands.  These files can
-then be processed by @code{groff} to produce a typeset document on a
-variety of devices.
-
-Likewise, @code{groff} should not be confused with a @dfn{word
-processor}, since that term connotes an integrated system that includes
-an editor and a text formatter.  Also, many word processors follow the
-@acronym{WYSIWYG} paradigm discussed earlier.
-
-Although @acronym{WYSIWYG} systems may be easier to use, they have a
-number of disadvantages compared to @code{troff}:
-
-@itemize @bullet
-@item
-They must be used on a graphics display to work on a document.
-
-@item
-Most of the @acronym{WYSIWYG} systems are either non-free or are not
-very portable.
-
-@item
-@code{troff} is firmly entrenched in all @acronym{UNIX} systems.
-
-@item
-It is difficult to have a wide range of capabilities available within
-the confines of a GUI/window system.
-
-@item
-It is more difficult to make global changes to a document.

-@node History, groff Capabilities, What Is groff?, Introduction
-@section History
-@cindex history
-
-@cindex @code{runoff}, the program
-@cindex @code{rf}, the program
-@code{troff} can trace its origins back to a formatting program called
-@code{runoff}, written by J.@tie{}E.@tie{}Saltzer, which ran on MIT's CTSS
-operating system in the mid-sixties.  This name came from the common
-phrase of the time ``I'll run off a document.''  Bob Morris ported it to
-the 635 architecture and called the program @code{roff} (an abbreviation
-of @code{runoff}).  It was rewritten as @code{rf} for the @w{PDP-7}
-(before having @acronym{UNIX}), and at the same time (1969), Doug
-McIllroy rewrote an extended and simplified version of @code{roff} in
-the @acronym{BCPL} programming language.
-
-@cindex @code{roff}, the program
-The first version of @acronym{UNIX} was developed on a @w{PDP-7} which
-was sitting around Bell Labs.  In 1971 the developers wanted to get a
-@w{PDP-11} for further work on the operating system.  In order to
-justify the cost for this system, they proposed that they would
-implement a document formatting system for the @acronym{AT&T} patents
-division.  This first formatting program was a reimplementation of
-McIllroy's @code{roff}, written by J.@tie{}F.@tie{}Ossanna.
-
-@cindex @code{nroff}, the program
-When they needed a more flexible language, a new version of @code{roff}
-called @code{nroff} (``Newer @code{roff}'') was written.  It had a much
-more complicated syntax, but provided the basis for all future versions.
-When they got a Graphic Systems CAT Phototypesetter, Ossanna wrote a
-version of @code{nroff} that would drive it.  It was dubbed
-@code{troff}, for ``typesetter @code{roff}'', although many people have
-speculated that it actually means ``Times @code{roff}'' because of the
-use of the Times font family in @code{troff} by default.  As such, the
-name @code{troff} is pronounced `@w{t-roff}' rather than `trough'.
-
-With @code{troff} came @code{nroff} (they were actually the same program
-except for some @samp{#ifdef}s), which was for producing output for line
-printers and character terminals.  It understood everything @code{troff}
-did, and ignored the commands which were not applicable (e.g.@: font
-changes).
-
-Since there are several things which cannot be done easily in
-@code{troff}, work on several preprocessors began.  These programs would
-transform certain parts of a document into @code{troff}, which made a
-very natural use of pipes in @acronym{UNIX}.
-
-The @code{eqn} preprocessor allowed mathematical formulæ to be
-specified in a much simpler and more intuitive manner.  @code{tbl} is a
-preprocessor for formatting tables.  The @code{refer} preprocessor (and
-the similar program, @code{bib}) processes citations in a document
-according to a bibliographic database.
-
-Unfortunately, Ossanna's @code{troff} was written in @w{PDP-11} assembly
-language and produced output specifically for the CAT phototypesetter.
-He rewrote it in C, although it was now 7000@tie{}lines of uncommented
-code and still dependent on the CAT.  As the CAT became less common, and
-was no longer supported by the manufacturer, the need to make it support
-other devices became a priority.  However, before this could be done,
-Ossanna was killed in a car accident.
-
-@pindex ditroff
-@cindex @code{ditroff}, the program
-So, Brian Kernighan took on the task of rewriting @code{troff}.  The
-newly rewritten version produced device independent code which was
-very easy for postprocessors to read and translate to the appropriate
-printer codes.  Also, this new version of @code{troff} (called
-@code{ditroff} for ``device independent @code{troff}'') had several
-extensions, which included drawing functions.
-
-Due to the additional abilities of the new version of @code{troff},
-several new preprocessors appeared.  The @code{pic} preprocessor
-provides a wide range of drawing functions.  Likewise the @code{ideal}
-preprocessor did the same, although via a much different paradigm.  The
-@code{grap} preprocessor took specifications for graphs, but, unlike
-other preprocessors, produced @code{pic} code.
-
-James Clark began work on a GNU implementation of @code{ditroff} in
-early@tie{}1989.  The first version, @code{groff}@tie{}0.3.1, was released
-June@tie{}1990.  @code{groff} included:
-
-@itemize @bullet
-@item
-A replacement for @code{ditroff} with many extensions.
-
-@item
-The @code{soelim}, @code{pic}, @code{tbl}, and @code{eqn} preprocessors.
-
-@item
-Postprocessors for character devices, @sc{PostScript}, @TeX{} DVI, and
-X@tie{}Windows.  GNU @code{troff} also eliminated the need for a
-separate @code{nroff} program with a postprocessor which would produce
-@acronym{ASCII} output.
-
-@item
-A version of the @file{me} macros and an implementation of the
-@file{man} macros.
-@end itemize
-
-Also, a front-end was included which could construct the, sometimes
-painfully long, pipelines required for all the post- and preprocessors.
-
-Development of GNU @code{troff} progressed rapidly, and saw the
-additions of a replacement for @code{refer}, an implementation of the
-@file{ms} and @file{mm} macros, and a program to deduce how to format a
-document (@code{grog}).
-
-It was declared a stable (i.e.@: non-beta) package with the release of
-version@tie{}1.04 around November@tie{}1991.
-
-Beginning in@tie{}1999, @code{groff} has new maintainers (the package was
-an orphan for a few years).  As a result, new features and programs like
-@code{grn}, a preprocessor for gremlin images, and an output device to
-produce @acronym{HTML} output have been added.

-@cindex macro packages
-
-Since @code{groff} provides such low-level facilities, it can be quite
-difficult to use by itself.  However, @code{groff} provides a
-@dfn{macro} facility to specify how certain routine operations
-(e.g.@tie{}starting paragraphs, printing headers and footers, etc.)@:
-should be done.  These macros can be collected together into a @dfn{macro
-package}.  There are a number of macro packages available; the most
-common (and the ones described in this manual) are @file{man},
-@file{mdoc}, @file{me}, @file{ms}, and @file{mm}.

-@node Preprocessor Intro, Output device intro, Macro Package Intro, Introduction
-@section Preprocessors
-@cindex preprocessors
-
-Although @code{groff} provides most functions needed to format a
-document, some operations would be unwieldy (e.g.@: to draw pictures).
-Therefore, programs called @dfn{preprocessors} were written which
-understand their own language and produce the necessary @code{groff}
-operations.  These preprocessors are able to differentiate their own
-input from the rest of the document via markers.
-
-To use a preprocessor, @acronym{UNIX} pipes are used to feed the output
-from the preprocessor into @code{groff}.  Any number of preprocessors
-may be used on a given document; in this case, the preprocessors are
-linked together into one pipeline.  However, with @code{groff}, the user
-does not need to construct the pipe, but only tell @code{groff} what
-preprocessors to use.
-
-@code{groff} currently has preprocessors for producing tables
-(@code{tbl}), typesetting equations (@code{eqn}), drawing pictures
-(@code{pic} and @code{grn}), and for processing bibliographies
-(@code{refer}).  An associated program which is useful when dealing with
-preprocessors is @code{soelim}.
-
-A free implementation of @code{grap}, a preprocessor for drawing graphs,
-can be obtained as an extra package; @code{groff} can use @code{grap}
-also.
-
-There are other preprocessors in existence, but, unfortunately, no free
-implementations are available.  Among them are preprocessors for drawing
-mathematical pictures (@code{ideal}) and chemical structures
-(@code{chem}).

-and Eric Allman's papers on the @file{me} macro package.
-
-The section on the @file{man} macro package is partly based on
-Susan@tie{}G.@: Kleinmann's @file{groff_man} manual page written for the

-@cindex @code{groff} invocation
-
-This section focuses on how to invoke the @code{groff} front end.  This
-front end takes care of the details of constructing the pipeline among
-the preprocessors, @code{gtroff} and the postprocessor.
-
-It has become a tradition that GNU programs get the prefix @samp{g} to
-distinguish it from its original counterparts provided by the host (see
-@ref{Environment}, for more details).  Thus, for example, @code{geqn} is
-GNU @code{eqn}.  On operating systems like GNU/Linux or the Hurd, which
-don't contain proprietary versions of @code{troff}, and on
-MS-DOS/MS-Windows, where @code{troff} and associated programs are not
-available at all, this prefix is omitted since GNU @code{troff} is the
-only used incarnation of @code{troff}.  Exception: @samp{groff} is never
-replaced by @samp{roff}.
-
-In this document, we consequently say @samp{gtroff} when talking about
-the GNU @code{troff} program.  All other implementations of @code{troff}
-are called @acronym{AT&T} @code{troff} which is the common origin of
-all @code{troff} derivates (with more or less compatible changes).
-Similarly, we say @samp{gpic}, @samp{geqn}, etc.

-
-This section only documents options to the @code{groff} front end.  Many

-
-@Example
-groff [ -abceghilpstvzCEGNRSUVXZ ] [ -F@var{dir} ] [ -m@var{name} ]
-      [ -T@var{def} ] [ -f@var{fam} ] [ -w@var{name} ] [ -W@var{name} ]

-      [ @var{files}@dots{} ]
-@endExample
-
-The command line format for @code{gtroff} is as follows.
-
-@Example
-gtroff [ -abcivzCERU ] [ -w@var{name} ] [ -W@var{name} ] [ -d@var{cs} ]
-       [ -f@var{fam} ] [ -m@var{name} ] [ -n@var{num} ]

-       [ -F@var{dir} ] [ -M@var{dir} ] [ @var{files}@dots{} ]
-@endExample
-
-@noindent
-Obviously, many of the options to @code{groff} are actually passed on to
-@code{gtroff}.
-
-Options without an argument can be grouped behind a single@tie{}@option{-}.
-A filename of@tie{}@file{-} denotes the standard input.  It is possible to
-have whitespace between an option and its parameter.
-
-The @code{grog} command can be used to guess the correct @code{groff}
-command to format a file.
-
-Here's the description of the command-line options:
-
-@cindex command-line options
-@table @samp
-@item -h
-Print a help message.
-
-@item -e
-Preprocess with @code{geqn}.

-
-@item -s
-Preprocess with @code{gsoelim}.
-
-@item -c
-Suppress color output.
-
-@item -R
-Preprocess with @code{grefer}.  No mechanism is provided for passing
-arguments to @code{grefer} because most @code{grefer} options have
-equivalent commands which can be included in the file.  @xref{grefer},
-for more details.
-
-@pindex troffrc
-@pindex troffrc-end
-Note that @code{gtroff} also accepts a @option{-R} option, which is not
-accessible via @code{groff}.  This option prevents the loading of the
-@file{troffrc} and @file{troffrc-end} files.
-
-@item -v
-Make programs run by @code{groff} print out their version number.
-
-@item -V
-Print the pipeline on @code{stdout} instead of executing it.  If specified
-more than once, print the pipeline on @code{stderr} and execute it.
-
-@item -z
-Suppress output from @code{gtroff}.  Only error messages are printed.
-
-@item -Z
-Do not postprocess the output of @code{gtroff}.  Normally @code{groff}
-automatically runs the appropriate postprocessor.
-
-@item -P@var{arg}
-Pass @var{arg} to the postprocessor.  Each argument should be passed
-with a separate @option{-P} option.  Note that @code{groff} does not
-prepend @samp{-} to @var{arg} before passing it to the postprocessor.
-
-@item -l
-Send the output to a spooler for printing.  The command used for this is
-specified by the @code{print} command in the device description file
-(see @ref{Font Files}, for more info).  If not present, @option{-l} is
-ignored.
-
-@item -L@var{arg}
-Pass @var{arg} to the spooler.  Each argument should be passed with a
-separate @option{-L} option.  Note that @code{groff} does not prepend
-a @samp{-} to @var{arg} before passing it to the postprocessor.
-If the @code{print} keyword in the device description file is missing,
-@option{-L} is ignored.
-
-@item -T@var{dev}
-Prepare output for device @var{dev}.  The default device is @samp{ps},
-unless changed when @code{groff} was configured and built.  The
-following are the output devices currently available:
-
-@table @code
-@item ps

-means print every page between @var{m} and@tie{}@var{n}, @samp{-@var{n}}
-means print every page up to@tie{}@var{n}, @samp{@var{n}-} means print every

-
-@Example
-groff file
-@endExample
-
-@noindent
-This command processes @file{file} without a macro package or a
-preprocessor.  The output device is the default, @samp{ps}, and the
-output is sent to @code{stdout}.
-
-@Example
-groff -t -mandoc -Tascii file | less
-@endExample
-
-@noindent
-This is basically what a call to the @code{man} program does.
-@code{gtroff} processes the manual page @file{file} with the
-@file{mandoc} macro file (which in turn either calls the @file{man} or
-the @file{mdoc} macro package), using the @code{tbl} preprocessor and
-the @acronym{ASCII} output device.  Finally, the @code{less} pager
-displays the result.
-
-@Example
-groff -X -m me file
-@endExample
-
-@noindent
-Preview @file{file} with @code{gxditview}, using the @file{me} macro
-package.  Since no @option{-T} option is specified, use the default
-device (@samp{ps}).  Note that you can either say @w{@samp{-m me}} or
-@w{@samp{-me}}; the latter is an anachronism from the early days of
-@acronym{UNIX}.@footnote{The same is true for the other main macro
-packages that come with @code{groff}: @file{man}, @file{mdoc},
-@file{ms}, @file{mm}, and @file{mandoc}.  This won't work in general;
-for example, to load @file{trace.tmac}, either @samp{-mtrace} or
-@w{@samp{-m trace}} must be used.}
-
-@Example
-groff -man -rD1 -z file
-@endExample
-

-Check @file{file} with the @file{man} macro package, forcing
-double-sided printing -- don't produce any output.

-@pindex grog
-@code{grog} reads files, guesses which of the @code{groff} preprocessors
-and/or macro packages are required for formatting them, and prints the
-@code{groff} command including those options on the standard output.  It
-generates one or more of the options @option{-e}, @option{-man},
-@option{-me}, @option{-mm}, @option{-mom}, @option{-ms}, @option{-mdoc},
-@option{-mdoc-old}, @option{-p}, @option{-R}, @option{-g}, @option{-G},
-@option{-s}, and @option{-t}.
-
-A special file name@tie{}@file{-} refers to the standard input.  Specifying
-no files also means to read the standard input.  Any specified options
-are included in the printed command.  No space is allowed between
-options and their arguments.  The only options recognized are
-@option{-C} (which is also passed on) to enable compatibility mode, and
-@option{-v} to print the version number and exit.
-
-For example,
-
-@Example
-grog -Tdvi paper.ms
-@endExample
-
-@noindent
-guesses the appropriate command to print @file{paper.ms} and then prints
-it to the command line after adding the @option{-Tdvi} option.  For
-direct execution, enclose the call to @code{grog} in backquotes at the
-@acronym{UNIX} shell prompt:
-
-@Example
-`grog -Tdvi paper.ms` > paper.dvi
-@endExample
-
-@noindent
-As seen in the example, it is still necessary to redirect the output to
-something meaningful (i.e.@: either a file or a pager program like

-@section Basics
-@cindex basics of macros
-@cindex macro basics
-
-This section covers some of the basic concepts necessary to understand
-how to use a macro package.@footnote{This section is derived from
-@cite{Writing Papers with nroff using -me} by Eric P.@tie{}Allman.}
-References are made throughout to more detailed information, if desired.
-
-@code{gtroff} reads an input file prepared by the user and outputs a
-formatted document suitable for publication or framing.  The input
-consists of text, or words to be printed, and embedded commands
-(@dfn{requests} and @dfn{escapes}), which tell @code{gtroff} how to
-format the output.  For more detail on this, see @ref{Embedded
-Commands}.
-
-The word @dfn{argument} is used in this chapter to mean a word or number
-which appears on the same line as a request, and which modifies the
-meaning of that request.  For example, the request
-
-@Example
-.sp
-@endExample
-
-@noindent
-spaces one line, but
-
-@Example
-.sp 4
-@endExample
-
-@noindent
-spaces four lines.  The number@tie{}4 is an argument to the @code{sp}
-request which says to space four lines instead of one.  Arguments are
-separated from the request and from each other by spaces (@emph{no}
-tabs).  More details on this can be found in @ref{Request and Macro
-Arguments}.
-
-The primary function of @code{gtroff} is to collect words from input
-lines, fill output lines with those words, justify the right-hand margin
-by inserting extra spaces in the line, and output the result.  For
-example, the input:
-
-@Example
-Now is the time
-for all good men
-to come to the aid
-of their party.
-Four score and seven
-years ago, etc.
-@endExample
-
-@noindent
-is read, packed onto output lines, and justified to produce:
-
-@quotation
-Now is the time for all good men to come to the aid of their party.
-Four score and seven years ago, etc.
-@end quotation
-
-@cindex break
-@cindex line break
-Sometimes a new output line should be started even though the current
-line is not yet full; for example, at the end of a paragraph.  To do
-this it is possible to cause a @dfn{break}, which starts a new output
-line.  Some requests cause a break automatically, as normally do blank
-input lines and input lines beginning with a space.
-
-Not all input lines are text to be formatted.  Some input lines are
-requests which describe how to format the text.  Requests always have a
-period (@samp{.}) or an apostrophe (@samp{'}) as the first character of
-the input line.
-
-The text formatter also does more complex things, such as automatically
-numbering pages, skipping over page boundaries, putting footnotes in the
-correct place, and so forth.
-
-Here are a few hints for preparing text for input to @code{gtroff}.
-
-@itemize @bullet
-@item
-First, keep the input lines short.  Short input lines are easier to
-edit, and @code{gtroff} packs words onto longer lines anyhow.
-
-@item
-In keeping with this, it is helpful to begin a new line after every
-comma or phrase, since common corrections are to add or delete sentences
-or phrases.
-
-@item
-End each sentence with two spaces -- or better, start each sentence on a
-new line.  @code{gtroff} recognizes characters that usually end a
-sentence, and inserts sentence space accordingly.
-
-@item
-Do not hyphenate words at the end of lines -- @code{gtroff} is smart
-enough to hyphenate words as needed, but is not smart enough to take
-hyphens out and join a word back together.  Also, words such as
-``mother-in-law'' should not be broken over a line, since then a space
-can occur where not wanted, such as ``@w{mother- in}-law''.
-@end itemize
-
-@cindex double-spacing (@code{ls})
-@cindex spacing
-@code{gtroff} double-spaces output text automatically if you use the
-request @w{@samp{.ls 2}}.  Reactivate single-spaced mode by typing
-@w{@samp{.ls 1}}.@footnote{If you need finer granularity of the
-vertical space, use the @code{pvs} request (@pxref{Changing Type
-Sizes}).}
-
-A number of requests allow to change the way the output looks,
-sometimes called the @dfn{layout} of the output page.  Most of these
-requests adjust the placing of @dfn{whitespace} (blank lines or
-spaces).
-
-@cindex new page (@code{bp})
-The @code{bp} request starts a new page, causing a line break.
-
-@cindex blank line (@code{sp})
-@cindex empty line (@code{sp})
-@cindex line, empty (@code{sp})
-The request @w{@samp{.sp @var{N}}} leaves @var{N}@tie{}lines of blank
-space.  @var{N}@tie{}can be omitted (meaning skip a single line) or can
-be of the form @var{N}i (for @var{N}@tie{}inches) or @var{N}c (for
-@var{N}@tie{}centimeters).  For example, the input:
-
-@Example
-.sp 1.5i
-My thoughts on the subject
-.sp
-@endExample
-
-@noindent
-leaves one and a half inches of space, followed by the line ``My
-thoughts on the subject'', followed by a single blank line (more
-measurement units are available, see @ref{Measurements}).
-
-@cindex centering lines (@code{ce})
-@cindex lines, centering (@code{ce})
-Text lines can be centered by using the @code{ce} request.  The line
-after @code{ce} is centered (horizontally) on the page.  To center more
-than one line, use @w{@samp{.ce @var{N}}} (where @var{N} is the number
-of lines to center), followed by the @var{N}@tie{}lines.  To center many
-lines without counting them, type:
-
-@Example
-.ce 1000
-lines to center
-.ce 0
-@endExample
-
-@noindent
-The @w{@samp{.ce 0}} request tells @code{groff} to center zero more
-lines, in other words, stop centering.

-@code{gtroff} provides very low-level operations for formatting a
-document.  There are many common routine operations which are done in
-all documents.  These common operations are written into @dfn{macros}
-and collected into a @dfn{macro package}.
-
-All macro packages provide certain common capabilities which fall into
-the following categories.

-@subsection Paragraphs
-@cindex paragraphs
-
-One of the most common and most used capability is starting a
-paragraph.  There are a number of different types of paragraphs, any
-of which can be initiated with macros supplied by the macro package.
-Normally, paragraphs start with a blank line and the first line
-indented, like the text in this manual.  There are also block style
-paragraphs, which omit the indentation:
-
-@Example
-Some   men  look   at  constitutions   with  sanctimonious
-reverence, and deem them like the ark of the covenant, too
-sacred to be touched.
-@endExample
-
-@noindent
-And there are also indented paragraphs which begin with a tag or label
-at the margin and the remaining text indented.
-
-@Example
-one   This is  the first paragraph.  Notice  how the first
-      line of  the resulting  paragraph lines up  with the
-      other lines in the paragraph.
-@endExample
-@Example
-longlabel
-      This  paragraph   had  a  long   label.   The  first
-      character of text on the first line does not line up
-      with  the  text  on  second  and  subsequent  lines,
-      although they line up with each other.
-@endExample
-
-A variation of this is a bulleted list.
-
-@Example
-.     Bulleted lists start with a bullet.   It is possible
-      to use other glyphs instead of the bullet.  In nroff
-      mode using the ASCII character set for output, a dot
-      is used instead of a real bullet.

-@node Sections and Chapters, Headers and Footers, Paragraphs, Common Features
-@subsection Sections and Chapters
-
-Most macro packages supply some form of section headers.  The simplest
-kind is simply the heading on a line by itself in bold type.  Others
-supply automatically numbered section heading or different heading
-styles at different levels.  Some, more sophisticated, macro packages
-supply macros for starting chapters and appendices.
-
-@c ---------------------------------------------------------------------
-
-@node Headers and Footers, Page Layout Adjustment, Sections and Chapters, Common Features
-@subsection Headers and Footers
-
-Every macro package gives some way to manipulate the @dfn{headers} and
-@dfn{footers} (also called @dfn{titles}) on each page.  This is text
-put at the top and bottom of each page, respectively, which contain
-data like the current page number, the current chapter title, and so
-on.  Its appearance is not affected by the running text.  Some packages
-allow for different ones on the even and odd pages (for material printed
-in a book form).
-
-The titles are called @dfn{three-part titles}, that is, there is a
-left-justified part, a centered part, and a right-justified part.  An
-automatically generated page number may be put in any of these fields
-with the @samp{%} character (see @ref{Page Layout}, for more details).
-
-@c ---------------------------------------------------------------------
-
-@node Page Layout Adjustment, Displays, Headers and Footers, Common Features
-@subsection Page Layout
-
-Most macro packages let the user specify top and bottom margins and
-other details about the appearance of the printed pages.
-
-@c ---------------------------------------------------------------------
-
-@node Displays, Footnotes and Annotations, Page Layout Adjustment, Common Features
-@subsection Displays
-@cindex displays
-
-@dfn{Displays} are sections of text to be set off from the body of
-the paper.  Major quotes, tables, and figures are types of displays, as
-are all the examples used in this document.
-
-@cindex quotes, major
-@cindex major quotes
-@dfn{Major quotes} are quotes which are several lines long, and hence
-are set in from the rest of the text without quote marks around them.
-
-@cindex list
-A @dfn{list} is an indented, single-spaced, unfilled display.  Lists
-should be used when the material to be printed should not be filled and
-justified like normal text, such as columns of figures or the examples
-used in this paper.
-
-@cindex keep
-A @dfn{keep} is a display of lines which are kept on a single page if
-possible.  An example for a keep might be a diagram.  Keeps differ from
-lists in that lists may be broken over a page boundary whereas keeps are
-not.
-
-@cindex keep, floating
-@cindex floating keep
-@dfn{Floating keeps} move relative to the text.  Hence, they are good for
-things which are referred to by name, such as ``See figure@tie{}3''.  A
-floating keep appears at the bottom of the current page if it fits;
-otherwise, it appears at the top of the next page.  Meanwhile, the
-surrounding text `flows' around the keep, thus leaving no blank areas.

-
-@node Footnotes and Annotations, Table of Contents, Displays, Common Features
-@subsection Footnotes and Annotations
-@cindex footnotes
-@cindex annotations
-
-There are a number of requests to save text for later printing.
-
-@dfn{Footnotes} are printed at the bottom of the current page.
-
-@cindex delayed text
-@dfn{Delayed text} is very similar to a footnote except that it is
-printed when called for explicitly.  This allows a list of references to
-appear (for example) at the end of each chapter, as is the convention in
-some disciplines.
-
-Most macro packages which supply this functionality also supply a means
-of automatically numbering either type of annotation.
-
-@c ---------------------------------------------------------------------
-
-@node Table of Contents, Indices, Footnotes and Annotations, Common Features
-@subsection Table of Contents
-@cindex table of contents
-@cindex contents, table of
-
-@dfn{Tables of contents} are a type of delayed text having a tag
-(usually the page number) attached to each entry after a row of dots.
-The table accumulates throughout the paper until printed, usually after
-the paper has ended.  Many macro packages provide the ability to have
-several tables of contents (e.g.@: a standard table of contents, a list
-of tables, etc).
-
-@c ---------------------------------------------------------------------
-
-@node Indices, Paper Formats, Table of Contents, Common Features
-@subsection Indices
-@cindex index, in macro package
-
-While some macro packages use the term @dfn{index}, none actually
-provide that functionality.  The facilities they call indices are
-actually more appropriate for tables of contents.
-
-@pindex makeindex
-To produce a real index in a document, external tools like the
-@code{makeindex} program are necessary.
-
-@c ---------------------------------------------------------------------
-
-@node Paper Formats, Multiple Columns, Indices, Common Features
-@subsection Paper Formats
-@cindex paper formats
-
-Some macro packages provide stock formats for various kinds of
-documents.  Many of them provide a common format for the title and
-opening pages of a technical paper.  The @file{mm} macros in particular
-provide formats for letters and memoranda.
-
-@c ---------------------------------------------------------------------
-
-@node Multiple Columns, Font and Size Changes, Paper Formats, Common Features

-
-@c ---------------------------------------------------------------------
-
-@node Predefined Strings, Preprocessor Support, Font and Size Changes, Common Features
-@subsection Predefined Strings
-
-Most macro packages provide various predefined strings for a variety of

-various special characters.
-
-@c ---------------------------------------------------------------------
-
-@node Preprocessor Support, Configuration and Customization, Predefined Strings, Common Features
-@subsection Preprocessor Support
-
-All macro packages provide support for various preprocessors and may
-extend their functionality.
-
-For example, all macro packages mark tables (which are processed with
-@code{gtbl}) by placing them between @code{TS} and @code{TE} macros.
-The @file{ms} macro package has an option, @samp{.TS@tie{}H}, that prints
-a caption at the top of a new page (when the table is too long to fit on
-a single page).

-
-The command line format for using the @file{man} macros with
-@code{groff} is:
-
-@Example
-groff -m man [ -rLL=@var{length} ] [ -rLT=@var{length} ] [ -rFT=@var{dist} ]
-      [ -rcR=1 ] [ -rC1 ] [ -rD1 ] [-rHY=@var{flags} ]
-      [ -rP@var{nnn} ] [ -rS@var{xx} ] [ -rX@var{nnn} ]
-      [ -rIN=@var{length} ] [ -rSN=@var{length} ] [ @var{files}@dots{} ]
-@endExample
-
-@noindent
-It is possible to use @samp{-man} instead of @w{@samp{-m man}}.
-
-@table @code
-@item -rcR=1
-This option (the default if a TTY output device is used) creates a
-single, very long page instead of multiple pages.  Use @code{-rcR=0}
-to disable it.
-
-@item -rC1
-If more than one manual page is given on the command line, number the
-pages continuously, rather than starting each at@tie{}1.
-
-@item -rD1
-Double-sided printing.  Footers for even and odd pages are formatted
-differently.
-
-@item -rFT=@var{dist}
-Set the position of the footer text to @var{dist}.  If positive, the
-distance is measured relative to the top of the page, otherwise it is
-relative to the bottom.  The default is @minus{}0.5@dmn{i}.
-
-@item -rHY=@var{flags}
-Set hyphenation flags.  Possible values are 1@tie{}to hyphenate without
-restrictions, 2@tie{} to not hyphenate the last word on a page,
-4@tie{}to not hyphenate the last two characters of a word, and
-8@tie{}to not hyphenate the first two characters of a word.  These
-values are additive; the default is@tie{}14.
-
-@item -rIN=@var{length}
-Set the body text indentation to @var{length}.
-If not specified, the indentation defaults to 7@dmn{n}
-(7@tie{}characters) in nroff mode and 7.2@dmn{n} otherwise.
-For nroff, this value should always be an integer multiple of unit @samp{n}
-to get consistent indentation.
-
-@item -rLL=@var{length}
-Set line length to @var{length}.  If not specified, the line length
-is set to respect any value set by a prior @samp{ll} request (which
-@emph{must} be in effect when the @samp{TH} macro is invoked), if
-this differs from the built-in default for the formatter; otherwise it
-defaults to 78@dmn{n} in nroff mode (this is 78 characters per
-line) and 6.5@dmn{i} in troff mode.@footnote{Note that the use of
-a @samp{.ll @var{length}} request to initialize the line length, prior
-to use of the @samp{TH} macro, is supported for backward compatibility
-with some versions of the @code{man} program.  @emph{Always} use the
-@option{-rLL=@var{length}} option, or an equivalent @samp{.nr LL @var{length}}
-request, in preference to such a @samp{.ll @var{length}} request.
-In particular, note that in nroff mode, the request @samp{.ll 65n},
-(with any @var{length} expression which evaluates equal to 65@dmn{n},
-i.e., the formatter's default line length in nroff mode), will @emph{not}
-set the line length to 65@dmn{n} (it will be adjusted to the @code{man}
-macro package's default setting of 78@dmn{n}), whereas the use of the
-@option{-rLL=65n} option, or the @samp{.nr LL 65n}
-request @emph{will} establish a line length of 65@dmn{n}.}
-
-@item -rLT=@var{length}
-Set title length to @var{length}.  If not specified, the title length
-defaults to the line length.
-
-@item -rP@var{nnn}
-Page numbering starts with @var{nnn} rather than with@tie{}1.
-
-@item -rS@var{xx}
-Use @var{xx} (which can be 10, 11, or@tie{}12@dmn{pt}) as the base
-document font size instead of the default value of@tie{}10@dmn{pt}.
-
-@item -rSN=@var{length}
-Set the indentation for sub-subheadings to @var{length}.
-If not specified, the indentation defaults to 3@dmn{n}.
-
-@item -rX@var{nnn}
-After page @var{nnn}, number pages as @var{nnn}a, @var{nnn}b,
-@var{nnn}c, etc.  For example, the option @option{-rX2} produces the
-following page numbers: 1, 2, 2a, 2b, 2c, etc.

-@subsection Usage
-@cindex @code{man} macros
-@cindex macros for manual pages [@code{man}]
-
-@pindex man.local
-This section describes the available macros for manual pages.  For
-further customization, put additional macros and requests into the file
-@file{man.local} which is loaded immediately after the @file{man}
-package.
-
-@Defmac {TH, title section [@Var{extra1} [@Var{extra2} [@Var{extra3}]]], man}
-Set the title of the man page to @var{title} and the section to
-@var{section}, which must have a value between 1 and@tie{}8.  The value
-of @var{section} may also have a string appended, e.g.@: @samp{.pm},
-to indicate a specific subsection of the man pages.
-
-Both @var{title} and @var{section} are positioned at the left and right
-in the header line (with @var{section} in parentheses immediately
-appended to @var{title}.  @var{extra1} is positioned in the middle of
-the footer line.  @var{extra2} is positioned at the left in the footer
-line (or at the left on even pages and at the right on odd pages if
-double-sided printing is active).  @var{extra3} is centered in the
-header line.
-
-For @acronym{HTML} output, headers and footers are completely suppressed.
-
-Additionally, this macro starts a new page; the new line number is@tie{}1
-again (except if the @option{-rC1} option is given on the command line)
--- this feature is intended only for formatting multiple man pages; a
-single man page should contain exactly one @code{TH} macro at the
-beginning of the file.
-@endDefmac
-
-@Defmac {SH, [@Var{heading}], man}
-Set up an unnumbered section heading sticking out to the left.  Prints
-out all the text following @code{SH} up to the end of the line (or the
-text in the next line if there is no argument to @code{SH}) in bold
-face (or the font specified by the string @code{HF}), one size larger than
-the base document size.  Additionally, the left margin and the indentation
-for the following text is reset to its default value.
-@endDefmac
-
-@Defmac {SS, [@Var{heading}], man}
-Set up an unnumbered (sub)section heading.  Prints out all the text
-following @code{SS} up to the end of the line (or the text in the next
-line if there is no argument to @code{SS}) in bold face (or the font
-specified by the string @code{HF}), at the same size as the base document
-size.  Additionally, the left margin and the indentation for the
-following text is reset to its default value.
-@endDefmac
-
-@Defmac {TP, [@Var{nnn}], man}
-Set up an indented paragraph with label.  The indentation is set to
-@var{nnn} if that argument is supplied (the default unit is @samp{n}
-if omitted), otherwise it is set to the previous indentation value
-specified with @code{TP}, @code{IP}, or @code{HP} (or to the default
-value if none of them have been used yet).
-
-The first line of text following this macro is interpreted as a string
-to be printed flush-left, as it is appropriate for a label.  It is not
-interpreted as part of a paragraph, so there is no attempt to fill the
-first line with text from the following input lines.  Nevertheless, if
-the label is not as wide as the indentation the paragraph starts
-at the same line (but indented), continuing on the following lines.
-If the label is wider than the indentation the descriptive part
-of the paragraph begins on the line following the label, entirely
-indented.  Note that neither font shape nor font size of the label is
-set to a default value; on the other hand, the rest of the text has
-default font settings.
-@endDefmac
-
-@DefmacList {LP, , man}
-@DefmacItem {PP, , man}
-@DefmacListEnd {P, , man}
-These macros are mutual aliases.  Any of them causes a line break at
-the current position, followed by a vertical space downwards by the
-amount specified by the @code{PD} macro.  The font size and shape are
-reset to the default value (10@dmn{pt} roman if no @option{-rS} option
-is given on the command line).  Finally, the current left margin and the
-indentation is restored.
-@endDefmac
-
-@Defmac {IP, [@Var{designator} [@Var{nnn}]], man}
-Set up an indented paragraph, using @var{designator} as a tag to mark
-its beginning.  The indentation is set to @var{nnn} if that argument
-is supplied (default unit is @samp{n}), otherwise it is set to the
-previous indentation value specified with @code{TP}, @code{IP}, or
-@code{HP} (or the default value if none of them have been used yet).
-Font size and face of the paragraph (but not the designator) are reset
-to their default values.
-
-To start an indented paragraph with a particular indentation but without
-a designator, use @samp{""} (two double quotes) as the first argument of
-@code{IP}.
-
-For example, to start a paragraph with bullets as the designator and
-4@tie{}en indentation, write
-
-@Example
-.IP \(bu 4
-@endExample
-@endDefmac
-
-@Defmac {HP, [@Var{nnn}], man}
-@cindex hanging indentation [@code{man}]
-@cindex @code{man} macros, hanging indentation
-Set up a paragraph with hanging left indentation.  The indentation is
-set to @var{nnn} if that argument is supplied (default unit is
-@samp{n}), otherwise it is set to the previous indentation value
-specified with @code{TP}, @code{IP}, or @code{HP} (or the default
-value if non of them have been used yet).  Font size and face are reset
-to their default values.
-@endDefmac
-
-@Defmac {RS, [@Var{nnn}], man}
-@cindex left margin, how to move [@code{man}]
-@cindex @code{man} macros, moving left margin
-Move the left margin to the right by the value @var{nnn} if specified
-(default unit is @samp{n}); otherwise it is set to the previous
-indentation value specified with @code{TP}, @code{IP}, or @code{HP}
-(or to the default value if none of them have been used yet).  The
-indentation value is then set to the default.
-
-Calls to the @code{RS} macro can be nested.
-@endDefmac
-
-@Defmac {RE, [@Var{nnn}], man}
-Move the left margin back to level @var{nnn}, restoring the previous left
-margin.  If no argument is given, it moves one level back.  The first
-level (i.e., no call to @code{RS} yet) has number@tie{}1, and each call
-to @code{RS} increases the level by@tie{}1.
-@endDefmac
-
-@cindex line breaks, with vertical space [@code{man}]
-@cindex @code{man} macros, line breaks with vertical space
-To summarize, the following macros cause a line break with the insertion
-of vertical space (which amount can be changed with the @code{PD}
-macro): @code{SH}, @code{SS}, @code{TP}, @code{LP} (@code{PP},
-@code{P}), @code{IP}, and @code{HP}.

-@subsection Introduction to @file{ms}
-
-The original @file{-ms} macros were included with @acronym{AT&T}
-@code{troff} as well as the @file{man} macros.  While the @file{man}
-package is intended for brief documents that can be read on-line as
-well as printed, the @file{ms} macros are suitable for longer
-documents that are meant to be printed rather than read on-line.
-
-The @file{ms} macro package included with @code{groff} is a complete,
-bottom-up re-implementation.  Several macros (specific to
-@acronym{AT&T} or Berkeley) are not included, while several new
-commands are.  @xref{Differences from AT&T ms}, for more information.
-
-@c ---------------------------------------------------------------------
-
-@node General ms Structure, ms Document Control Registers, ms Intro, ms
-@subsection General structure of an @file{ms} document
-@cindex @code{ms} macros, general structure
-
-The @file{ms} macro package expects a certain amount of structure, but
-not as much as packages such as @file{man} or @file{mdoc}.
-
-The simplest documents can begin with a paragraph macro (such as
-@code{LP} or @code{PP}), and consist of text separated by paragraph
-macros or even blank lines.  Longer documents have a structure as
-follows:
-
-@table @strong
-@item Document type
-If you invoke the @code{RP} (report) macro on the first line of the
-document, @code{groff} prints the cover page information on its own
-page; otherwise it prints the information on the first page with your
-document text immediately following.  Other document formats found in
-@acronym{AT&T} @code{troff} are specific to @acronym{AT&T} or
-Berkeley, and are not supported in @code{groff}.
-
-@item Format and layout
-By setting number registers, you can change your document's type (font
-and size), margins, spacing, headers and footers, and footnotes.
-@xref{ms Document Control Registers}, for more details.
-
-@item Cover page
-A cover page consists of a title, the author's name and institution,
-an abstract, and the date.@footnote{Actually, only the title is
-required.}  @xref{ms Cover Page Macros}, for more details.
-
-@item Body
-Following the cover page is your document.  You can use the @file{ms}
-macros to write reports, letters, books, and so forth.  The package is
-designed for structured documents, consisting of paragraphs
-interspersed with headings and augmented by lists, footnotes, tables,
-and other common constructs.  @xref{ms Body Text}, for more details.
-
-@item Table of contents
-Longer documents usually include a table of contents, which you can
-invoke by placing the @code{TC} macro at the end of your document.
-The @file{ms} macros have minimal indexing facilities, consisting of
-the @code{IX} macro, which prints an entry on standard error.
-Printing the table of contents at the end is necessary since
-@code{groff} is a single-pass text formatter, thus it cannot determine
-the page number of each section until that section has actually been
-set and printed.  Since @file{ms} output is intended for hardcopy, you
-can manually relocate the pages containing the table of contents
-between the cover page and the body text after printing.

-@node ms Document Control Registers, ms Cover Page Macros, General ms Structure, ms
-@subsection Document control registers
-@cindex @code{ms} macros, document control registers
-
-The following is a list of document control number registers.  For the
-sake of consistency, set registers related to margins at the beginning
-of your document, or just after the @code{RP} macro.  You can set
-other registers later in your document, but you should keep them
-together at the beginning to make them easy to find and edit as
-necessary.
-
-@unnumberedsubsubsec Margin Settings
-
-@Defmpreg {PO, ms}
-Defines the page offset (i.e., the left margin).  There is no explicit
-right margin setting; the combination of the @code{PO} and @code{LL}
-registers implicitly define the right margin width.
-
-Effective: next page.
-
-Default value: 1@dmn{i}.
-@endDefmpreg
-
-@Defmpreg {LL, ms}
-Defines the line length (i.e., the width of the body text).
-
-Effective: next paragraph.
-
-Default: 6@dmn{i}.
-@endDefmpreg
-
-@Defmpreg {LT, ms}
-Defines the title length (i.e., the header and footer width).  This
-is usually the same as @code{LL}, but not necessarily.
-
-Effective: next paragraph.
-
-Default: 6@dmn{i}.
-@endDefmpreg
-
-@Defmpreg {HM, ms}
-Defines the header margin height at the top of the page.
-
-Effective: next page.
-
-Default: 1@dmn{i}.
-@endDefmpreg
-
-@Defmpreg {FM, ms}
-Defines the footer margin height at the bottom of the page.
-
-Effective: next page.
-
-Default: 1@dmn{i}.
-@endDefmpreg
-
-@unnumberedsubsubsec Text Settings
-
-@Defmpreg {PS, ms}
-Defines the point size of the body text.  If the value is larger than
-or equal to 1000, divide it by 1000 to get a fractional point size.
-For example, @samp{.nr PS 10250} sets the document's point size to
-10.25@dmn{p}.
-
-Effective: next paragraph.
-
-Default: 10@dmn{p}.
-@endDefmpreg
-
-@Defmpreg {VS, ms}
-Defines the space between lines (line height plus leading).  If the
-value is larger than or equal to 1000, divide it by 1000 to get a
-fractional point size.  Due to backwards compatibility, @code{VS} must
-be smaller than 40000 (this is 40.0@dmn{p}).
-
-Effective: next paragraph.
-
-Default: 12@dmn{p}.
-@endDefmpreg
-
-@Defmpreg {PSINCR, ms}
-Defines an increment in point size, which will be applied to section
-headings at nesting levels below the value specified in @code{GROWPS}.
-The value of @code{PSINCR} should be specified in points, with the
-@dmn{p} scaling factor, and may include a fractional component; for
-example, @w{@samp{.nr PSINCR 1.5p}} sets a point size increment of
-1.5@dmn{p}.
-
-Effective: next section heading.
-
-Default: 1@dmn{p}.
-@endDefmpreg
-
-@Defmpreg {GROWPS, ms}
-Defines the heading level below which the point size increment set by
-@code{PSINCR} becomes effective.  Section headings at and above the
-level specified by @code{GROWPS} will be printed at the point size set
-by @code{PS}; for each level below the value of @code{GROWPS}, the
-point size will be increased in steps equal to the value of
-@code{PSINCR}.  Setting @code{GROWPS} to any value less than@tie{}2
-disables the incremental heading size feature.
-
-Effective: next section heading.
-
-Default: 0.
-@endDefmpreg
-
-@Defmpreg {HY, ms}
-Defines the hyphenation level.  @code{HY} sets safely the value of the
-low-level @code{hy} register.  Setting the value of @code{HY}
-to@tie{}0 is equivalent to using the @code{nh} request.
-
-Effective: next paragraph.
-
-Default: 14.
-@endDefmpreg
-
-@Defmpreg {FAM, ms}
-Defines the font family used to typeset the document.
-
-Effective: next paragraph.
-
-Default: as defined in the output device.
-@endDefmpreg
-
-@unnumberedsubsubsec Paragraph Settings
-

-@endDefmpreg
-
-@Defmpreg {QI, ms}
-Defines the indentation on both sides of a quoted (@code{QP} macro)
-paragraph.
-
-Effective: next paragraph.
-
-Default: 5@dmn{n}.
-@endDefmpreg
-
-@Defmpreg {PORPHANS, ms}
-Defines the minimum number of initial lines of any paragraph which
-should be kept together, to avoid orphan lines at the bottom of a
-page.  If a new paragraph is started close to the bottom of a page,
-and there is insufficient space to accommodate @code{PORPHANS} lines
-before an automatic page break, then the page break will be forced,
-before the start of the paragraph.
-
-Effective: next paragraph.
-
-Default: 1.
-@endDefmpreg
-
-@Defmpreg {HORPHANS, ms}
-Defines the minimum number of lines of the following paragraph which
-should be kept together with any section heading introduced by the
-@code{NH} or @code{SH} macros.  If a section heading is placed close
-to the bottom of a page, and there is insufficient space to
-accommodate both the heading and at least @code{HORPHANS} lines of the
-following paragraph, before an automatic page break, then the page
-break will be forced before the heading.
-

-@subsubsection Headings
-@cindex @code{ms} macros, headings
-
-Use headings to create a hierarchical structure for your document.
-The @file{ms} macros print headings in @strong{bold}, using the same
-font family and point size as the body text.
-
-The following describes the heading macros:
-
-@DefmacList {NH, @Var{curr-level}, ms}
-@DefmacListEnd {NH, @t{S} @Var{level0} @dots{}, ms}
-Numbered heading.  The argument is either a numeric argument to
-indicate the level of the heading, or the letter@tie{}@code{S}
-followed by numeric arguments to set the heading level explicitly.
-
-If you specify heading levels out of sequence, such as invoking
-@samp{.NH 3} after @samp{.NH 1}, @code{groff} prints a warning on
-standard error.
-@endDefmac
-
-@DefstrList {SN, ms}
-@DefstrItem {SN-DOT, ms}
-@DefstrListEnd {SN-NO-DOT, ms}
-After invocation of @code{NH}, the assigned section number is made
-available in the strings @code{SN-DOT} (exactly as it appears in the
-printed section heading) and @code{SN-NO-DOT} (with the final period
-omitted).  The string @code{SN} is also defined, as an alias for
-@code{SN-DOT}; if preferred, you may redefine it as an alias for
-@code{SN-NO-DOT}, by including the initialization
-
-@Example
-.ds SN-NO-DOT
-.als SN SN-NO-DOT
-@endExample
-
-@noindent
-@strong{before} your first use of @code{NH}, or simply
-
-@Example
-.als SN SN-NO-DOT
-@endExample
-
-@noindent
-@strong{after} your first use of @code{NH}.
-@endDefstr
-
-@Defmac {SH, [@Var{match-level}], ms}
-Unnumbered subheading.
-
-The optional @var{match-level} argument is a GNU extension.  It is a
-number indicating the level of the heading, in a manner analogous to
-the @var{curr-level} argument to @code{.NH}.  Its purpose is to match
-the point size, at which the heading is printed, to the size of a
-numbered heading at the same level, when the @code{GROWPS} and
-@code{PSINCR} heading size adjustment mechanism is in effect.
-@xref{ms Document Control Registers}.
-@endDefmac
-
-The @code{HORPHANS} register (@pxref{ms Document Control Registers})

-@node Highlighting in ms, Lists in ms, Headings in ms, ms Body Text
-@subsubsection Highlighting
-@cindex @code{ms} macros, highlighting
-
-The @file{ms} macros provide a variety of methods to highlight or
-emphasize text:
-
-@Defmac {B, [@Var{txt} [@Var{post} [@Var{pre}]]], ms}
-Sets its first argument in @strong{bold type}.  If you specify a
-second argument, @code{groff} prints it in the previous font after the
-bold text, with no intervening space (this allows you to set
-punctuation after the highlighted text without highlighting the
-punctuation).  Similarly, it prints the third argument (if any) in the
-previous font @strong{before} the first argument.  For example,
-
-@Example
-.B foo ) (
-@endExample
-
-prints (@strong{foo}).
-
-If you give this macro no arguments, @code{groff} prints all text
-following in bold until the next highlighting, paragraph, or heading
-macro.
-@endDefmac
-
-@Defmac {R, [@Var{txt} [@Var{post} [@Var{pre}]]], ms}
-Sets its first argument in roman (or regular) type.  It operates
-similarly to the @code{B}@tie{}macro otherwise.
-@endDefmac
-
-@Defmac {I, [@Var{txt} [@Var{post} [@Var{pre}]]], ms}
-Sets its first argument in @emph{italic type}.  It operates similarly
-to the @code{B}@tie{}macro otherwise.
-@endDefmac
-
-@Defmac {CW, [@Var{txt} [@Var{post} [@Var{pre}]]], ms}
-Sets its first argument in a @code{constant width face}.  It operates
-similarly to the @code{B}@tie{}macro otherwise.
-@endDefmac
-
-@Defmac {BI, [@Var{txt} [@Var{post} [@Var{pre}]]], ms}
-Sets its first argument in bold italic type.  It operates similarly to
-the @code{B}@tie{}macro otherwise.
-@endDefmac
-
-@Defmac {BX, [@Var{txt}], ms}
-Prints its argument and draws a box around it.  If you want to box a
-string that contains spaces, use a digit-width space (@code{\0}).
-@endDefmac
-
-@Defmac {UL, [@Var{txt} [@Var{post}]], ms}
-Prints its first argument with an underline.  If you specify a second
-argument, @code{groff} prints it in the previous font after the
-underlined text, with no intervening space.
-@endDefmac
-
-@Defmac {LG, , ms}
-Prints all text following in larger type (two points larger than the
-current point size) until the next font size, highlighting, paragraph,
-or heading macro.  You can specify this macro multiple times to
-enlarge the point size as needed.
-@endDefmac
-
-@Defmac {SM, , ms}
-Prints all text following in smaller type (two points smaller than the
-current point size) until the next type size, highlighting, paragraph,
-or heading macro.  You can specify this macro multiple times to reduce
-the point size as needed.
-@endDefmac
-
-@Defmac {NL, , ms}
-Prints all text following in the normal point size (that is, the value
-of the @code{PS} register).
-@endDefmac

-The @var{marker} is usually a bullet glyph (@code{\[bu]}) for
-unordered lists, a number (or auto-incrementing number register) for
-numbered lists, or a word or phrase for indented (glossary-style)
-lists.
-
-The @var{width} specifies the indentation for the body of each list
-item; its default unit is @samp{n}.  Once specified, the indentation
-remains the same for all list items in the document until specified
-again.

-@endExample
-
-In the last example, the @code{IP} macro places the definition on the
-same line as the term if it has enough space; otherwise, it breaks to
-the next line and starts the definition below the term.  This may or
-may not be the effect you want, especially if some of the definitions
-break and some do not.  The following examples show two possible ways
-to force a break.
-
-The first workaround uses the @code{br} request to force a break after
-printing the term or label.
-
-@Example
-@cartouche
-A glossary-style list:
-.IP lawyers 0.4i
-Two or more attorneys.
-.IP guns
-.br
-Firearms, preferably large-caliber.
-.IP money
-Gotta pay for those lawyers and guns!
-@end cartouche
-@endExample
-
-The second workaround uses the @code{\p} escape to force the break.
-Note the space following the escape; this is important.  If you omit
-the space, @code{groff} prints the first word on the same line as the
-term or label (if it fits) @strong{then} breaks the line.

-can be @dfn{kept} on a single page, or allowed to break across pages.
-
-@DefmacList {DS, @t{L}, ms}
-@DefmacItem {LD, , ms}
-@DefmacListEnd {DE, , ms}
-Left-justified display.  The @samp{.DS L} call generates a page break,
-if necessary, to keep the entire display on one page.  The @code{LD}

-entire display on one page.  The @code{CD} macro allows the display to
-break across pages.  The @code{DE} macro ends the display.
-@endDefmac
-
-@DefmacList {DS, @t{R}, ms}
-@DefmacItem {RD, , ms}
-@DefmacListEnd {DE, , ms}
-Right-justifies each line in the display.  The @samp{.DS R} call

-pages.  The @code{DE} macro ends the display.
-@endDefmac
-
-@DefmacList {Ds, , ms}
-@DefmacListEnd {De, , ms}
-These two macros were formerly provided as aliases for @code{DS} and
-@code{DE}, respectively.  They have been removed, and should no longer
-be used.  The original implementations of @code{DS} and @code{DE} are
-retained, and should be used instead.  X11 documents which actually

-
-On occasion, you may want to @dfn{keep} other text together on a page.
-For example, you may want to keep two paragraphs together, or a
-paragraph that refers to a table (or list, or other item) immediately
-following.  The @file{ms} macros provide the @code{KS} and @code{KE}
-macros for this purpose.
-
-@DefmacList {KS, , ms}
-@DefmacListEnd {KE, , ms}
-The @code{KS} macro begins a block of text to be kept on a single
-page, and the @code{KE} macro ends the block.
-@endDefmac
-
-@DefmacList {KF, , ms}
-@DefmacListEnd {KE, , ms}
-Specifies a @dfn{floating keep}; if the keep cannot fit on the current
-page, @code{groff} holds the contents of the keep and allows text
-following the keep (in the source file) to fill in the remainder of
-the current page.  When the page breaks, whether by an explicit
-@code{bp} request or by reaching the end of the page, @code{groff}
-prints the floating keep at the top of the new page.  This is useful
-for printing large graphics or tables that do not need to appear
-exactly where specified.
-@endDefmac
-
-You can also use the @code{ne} request to force a page break if there
-is not enough vertical space remaining on the page.
-
-Use the following macros to draw a box around a section of text (such
-as a display).
-
-@DefmacList {B1, , ms}
-@DefmacListEnd {B2, , ms}
-Marks the beginning and ending of text that is to have a box drawn
-around it.  The @code{B1} macro begins the box; the @code{B2} macro
-ends it.  Text in the box is automatically placed in a diversion
-(keep).

-However, if the current mode is single-column, starting a multi-column
-mode does @emph{not} force a page break.
-
-@Defmac {1C, , ms}
-Single-column mode.
-@endDefmac
-
-@Defmac {2C, , ms}
-Two-column mode.
-@endDefmac
-
-@Defmac {MC, [@Var{width} [@Var{gutter}]], ms}
-Multi-column mode.  If you specify no arguments, it is equivalent to
-the @code{2C} macro.  Otherwise, @var{width} is the width of each
-column and @var{gutter} is the space between columns.  The
-@code{MINGW} number register controls the default gutter width.

-@subsubsection Creating a table of contents
-@cindex @code{ms} macros, creating table of contents
-@cindex table of contents, creating [@code{ms}]
-
-The facilities in the @file{ms} macro package for creating a table of
-contents are semi-automated at best.  Assuming that you want the table
-of contents to consist of the document's headings, you need to repeat
-those headings wrapped in @code{XS} and @code{XE} macros.
-
-@DefmacList {XS, [@Var{page}], ms}
-@DefmacItem {XA, [@Var{page}], ms}
-@DefmacListEnd {XE, , ms}
-These macros define a table of contents or an individual entry in the
-table of contents, depending on their use.  The macros are very
-simple; they cannot indent a heading based on its level.  The easiest
-way to work around this is to add tabs to the table of contents
-string.  The following is an example:
-
-@Example
-@cartouche
-.NH 1
-Introduction
-.XS
-Introduction
-.XE
-.LP
-...
-.CW
-.NH 2
-Methodology
-.XS
-Methodology
-.XE
-.LP
-...
-@end cartouche
-@endExample
-
-You can manually create a table of contents by beginning with the
-@code{XS} macro for the first entry, specifying the page number for
-that entry as the argument to @code{XS}.  Add subsequent entries using
-the @code{XA} macro, specifying the page number for that entry as the
-argument to @code{XA}.  The following is an example:
-
-@Example
-@cartouche
-.XS 1
-Introduction
-.XA 2
-A Brief History of the Universe
-.XA 729
-Details of Galactic Formation
-...
-.XE
-@end cartouche
-@endExample
-@endDefmac
-
-@Defmac {TC, [@code{no}], ms}
-Prints the table of contents on a new page, setting the page number
-to@tie{}@strong{i} (Roman lowercase numeral one).  You should usually
-place this macro at the end of the file, since @code{groff} is a
-single-pass formatter and can only print what has been collected up to
-the point that the @code{TC} macro appears.
-
-The optional argument @code{no} suppresses printing the title
-specified by the string register @code{TOC}.
-@endDefmac
-
-@Defmac{PX, [@code{no}], ms}
-Prints the table of contents on a new page, using the current page
-numbering sequence.  Use this macro to print a manually-generated
-table of contents at the beginning of your document.
-
-The optional argument @code{no} suppresses printing the title
-specified by the string register @code{TOC}.
-@endDefmac
-
-The @cite{Groff and Friends HOWTO} includes a @code{sed} script that
-automatically inserts @code{XS} and @code{XE} macro entries after each
-heading in a document.
-
-Altering the @code{NH} macro to automatically build the table of
-contents is perhaps initially more difficult, but would save a great
-deal of time in the long run if you use @file{ms} regularly.

-@cindex @acronym{AT&T} @code{troff}, @code{ms} macro package differences
-
-This section lists the (minor) differences between the @code{groff
--ms} macros and @acronym{AT&T} @code{troff -ms} macros.
-
-@itemize @bullet
-@item
-The internals of @code{groff -ms} differ from the internals of
-@acronym{AT&T} @code{troff -ms}.  Documents that depend upon
-implementation details of @acronym{AT&T} @code{troff -ms} may not
-format properly with @code{groff -ms}.
-
-@item
-The general error-handling policy of @code{groff -ms} is to detect and
-report errors, rather than silently to ignore them.
-
-@item
-@code{groff -ms} does not work in compatibility mode (this is, with
-the @option{-C} option).
-
-@item
-There is no special support for typewriter-like devices.
-
-@item
-@code{groff -ms} does not provide cut marks.
-
-@item
-Multiple line spacing is not supported.  Use a larger vertical spacing
-instead.
-
-@item
-Some @acronym{UNIX} @code{ms} documentation says that the @code{CW}
-and @code{GW} number registers can be used to control the column width
-and gutter width, respectively.  These number registers are not used in
-@code{groff -ms}.
-
-@item
-Macros that cause a reset (paragraphs, headings, etc.@:) may change
-the indentation.  Macros that change the indentation do not increment
-or decrement the indentation, but rather set it absolutely.  This can
-cause problems for documents that define additional macros of their
-own.  The solution is to use not the @code{in} request but instead the
-@code{RS} and @code{RE} macros.
-
-@item
-To make @code{groff -ms} use the default page offset (which also
-specifies the left margin), the @code{PO} register must stay undefined
-until the first @file{-ms} macro is evaluated.  This implies that
-@code{PO} should not be used early in the document, unless it is
-changed also: Remember that accessing an undefined register
-automatically defines it.
-@end itemize
-
-@Defmpreg {GS, ms}
-This number register is set to@tie{}1 by the @code{groff -ms} macros,
-but it is not used by the @code{AT&T} @code{troff -ms} macros.
-Documents that need to determine whether they are being formatted with
-@code{AT&T} @code{troff -ms} or @code{groff -ms} should use this
-number register.

-@cindex naming conventions, @code{ms} macros
-
-The following conventions are used for names of macros, strings and
-number registers.  External names available to documents that use the
-@code{groff -ms} macros contain only uppercase letters and digits.
-
-Internally the macros are divided into modules; naming conventions are
-as follows:
-
-@itemize @bullet
-@item
-Names used only within one module are of the form
-@var{module}@code{*}@var{name}.
-
-@item
-Names used outside the module in which they are defined are of the
-form @var{module}@code{@@}@var{name}.
-
-@item
-Names associated with a particular environment are of the form
-@var{environment}@code{:}@var{name}; these are used only within the
-@code{par} module.
-
-@item
-@var{name} does not have a module prefix.
-
-@item
-Constructed names used to implement arrays are of the form
-@var{array}@code{!}@var{index}.
-@end itemize
-
-Thus the groff ms macros reserve the following names:
-
-@itemize @bullet
-@item
-Names containing the characters @code{*}, @code{@@},
-and@tie{}@code{:}.
-
-@item
-Names containing only uppercase letters and digits.

-@cindex filling
-@cindex adjusting

-@dfn{filling}.
-
-@cindex leading spaces
-@cindex spaces, leading and trailing
-@cindex extra spaces
-@cindex trailing spaces
-Once @code{gtroff} has a @dfn{filled} line, it tries to @dfn{adjust}
-it.  This means it widens the spacing between words until the text
-reaches the right margin (in the default adjustment mode).  Extra spaces
-between words are preserved, but spaces at the end of lines are ignored.
-Spaces at the front of a line cause a @dfn{break} (breaks are
-explained in @ref{Implicit Line Breaks}).

-
-@node Hyphenation, Sentences, Filling and Adjusting, Text
-@subsection Hyphenation
-@cindex hyphenation
-
-Since the odds are not great for finding a set of words, for every
-output line, which fit nicely on a line without inserting excessive
-amounts of space between words, @code{gtroff} hyphenates words so
-that it can justify lines without inserting too much space between
-words.  It uses an internal hyphenation algorithm (a simplified version
-of the algorithm used within @TeX{}) to indicate which words can be
-hyphenated and how to do so.  When a word is hyphenated, the first part
-of the word is added to the current filled line being output (with
-an attached hyphen), and the other portion is added to the next
-line to be filled.
-
-@xref{Manipulating Hyphenation}.
-
-@c ---------------------------------------------------------------------
-
-@node Sentences, Tab Stops, Hyphenation, Text
-@subsection Sentences
-@cindex sentences
-
-Although it is often debated, some typesetting rules say there should be
-different amounts of space after various punctuation marks.  For
-example, the @cite{Chicago typsetting manual} says that a period at the
-end of a sentence should have twice as much space following it as would
-a comma or a period as part of an abbreviation.
-
-@c XXX exact citation of Chicago manual
-
-@cindex sentence space
-@cindex space between sentences
-@cindex french-spacing
-@code{gtroff} does this by flagging certain characters (normally
-@samp{!}, @samp{?}, and @samp{.}) as @dfn{end-of-sentence} characters.
-When @code{gtroff} encounters one of these characters at the end of a
-line, it appends a normal space followed by a @dfn{sentence space} in
-the formatted output.  (This justifies one of the conventions mentioned
-in @ref{Input Conventions}.)
-
-@cindex transparent characters
-@cindex character, transparent
-@cindex @code{dg} glyph, at end of sentence
-@cindex @code{rq} glyph, at end of sentence
-@cindex @code{"}, at end of sentence
-@cindex @code{'}, at end of sentence
-@cindex @code{)}, at end of sentence
-@cindex @code{]}, at end of sentence
-@cindex @code{*}, at end of sentence
-In addition, the following characters and symbols are treated
-transparently while handling end-of-sentence characters: @samp{"},
-@samp{'}, @samp{)}, @samp{]}, @samp{*}, @code{\[dg]}, and @code{\[rq]}.
-
-See the @code{cflags} request in @ref{Using Symbols}, for more details.
-
-@cindex @code{\&}, at end of sentence
-To prevent the insertion of extra space after an end-of-sentence
-character (at the end of a line), append @code{\&}.

-@dfn{tabs} (normally code point @acronym{ASCII} @code{0x09} or
-@acronym{EBCDIC} @code{0x05}), in the input into movements to the next
-tabulator stop.  These tab stops are initially located every half inch
-across the page.  Using this, simple tables can be made easily.
-However, it can often be deceptive as the appearance (and width) of the
-text on a terminal and the results from @code{gtroff} can vary greatly.
-
-Also, a possible sticking point is that lines beginning with tab
-characters are still filled, again producing unexpected results.
-For example, the following input

-@cindex line break
-
-An important concept in @code{gtroff} is the @dfn{break}.  When a break

-line.
-
-@cindex blank line
-@cindex empty line
-@cindex line, blank
-@cindex blank line macro (@code{blm})
-There are several ways to cause a break in @code{gtroff}.  A blank

-space (effectively a blank line).  Note that this behaviour can be
-modified with the blank line macro request @code{blm}.
-@xref{Blank Line Traps}.
-
-@cindex fill mode
-@cindex mode, fill
-A line that begins with a space causes a break and the space is
-output at the beginning of the next line.  Note that this space isn't
-adjusted, even in fill mode.
-
-The end of file also causes a break -- otherwise the last line of
-the document may vanish!
-
-Certain requests also cause breaks, implicitly or explicitly.  This is

-
-Since @code{gtroff} does filling automatically, it is traditional in

-paragraphs.  These are some conventions commonly used when typing
-@code{gtroff} text:
-
-@itemize @bullet
-@item
-Break lines after punctuation, particularly at the end of a sentence
-and in other logical places.  Keep separate phrases on lines by
-themselves, as entire phrases are often added or deleted when editing.
-

-Try to keep lines less than 40-60@tie{}characters, to allow space for

-@cindex @code{u} unit
-@cindex unit, @code{u}
-@code{gtroff} (like many other programs) requires numeric parameters to
-specify various measurements.  Most numeric parameters@footnote{those
-that specify vertical or horizontal motion or a type size} may have a
-@dfn{measurement unit} attached.  These units are specified as a single
-character which immediately follows the number or expression.  Each of
-these units are understood, by @code{gtroff}, to be a multiple of its
-@dfn{basic unit}.  So, whenever a different measurement unit is
-specified @code{gtroff} converts this into its @dfn{basic units}.  This
-basic unit, represented by a @samp{u}, is a device dependent measurement
-which is quite small, ranging from 1/75@dmn{th} to 1/72000@dmn{th} of an
-inch.  The values may be given as fractional numbers; however,
-fractional basic units are always rounded to integers.

-Many requests take a default unit.  While this can be helpful at times,
-it can cause strange errors in some expressions.  For example, the line
-length request expects em units.  Here are several attempts to get a
-line length of 3.5@tie{}inches and their results:
-
-@Example
-3.5i      @result{}   3.5i
-7/2       @result{}   0i
-7/2i      @result{}   0i

-7i/2      @result{}   0.1i
-7i/2u     @result{}   3.5i
-@endExample
-
-@noindent
-Everything is converted to basic units first.  In the above example it
-is assumed that 1@dmn{i} equals@tie{}240@dmn{u}, and 1@dmn{m}
-equals@tie{}10@dmn{p} (thus 1@dmn{m} equals@tie{}33@dmn{u}).  The value
-7@dmn{i}/2 is first handled as 7@dmn{i}/2@dmn{m}, then converted to
-1680@dmn{u}/66@dmn{u} which is 25@dmn{u}, and this is approximately
-0.1@dmn{i}.  As can be seen, a scaling indicator after a closing
-parenthesis is simply ignored.
-

-details): @code{0x00}, @code{0x0B}, @code{0x0D}-@code{0x1F},
-@code{0x80}-@code{0x9F}.

-@code{0x0B}, @code{0x0D}-@code{0x14}, @code{0x17}-@code{0x1F},
-@code{0x30}-@code{0x3F}.
-
-Currently, some of these reserved codepoints are used internally, thus
-making it non-trivial to extend @code{gtroff} to cover Unicode or other
-character sets and encodings which use characters of these ranges.
-
-Note that invalid characters are removed before parsing; an
-identifier @code{foo}, followed by an invalid character, followed by
-@code{bar} is treated as @code{foobar}.

-@noindent
-Note that identifiers longer than two characters with a closing bracket
-(@samp{]}) in its name can't be accessed with escape sequences which

-@cindex macro names, starting with @code{[} or @code{]}, and @code{refer}
-To avoid problems with the @code{refer} preprocessor, macro names
-should not start with @samp{[} or @samp{]}.  Due to backwards
-compatibility, everything after @samp{.[} and @samp{.]} is handled as
-a special argument to @code{refer}.  For example, @samp{.[foo} makes
-@code{refer} to start a reference, using @samp{foo} as a parameter.
-
-@Defesc {\\A, ', ident, '}
-Test whether an identifier @var{ident} is valid in @code{gtroff}.  It
-expands to the character@tie{}1 or@tie{}0 according to whether its
-argument (usually delimited by quotes) is or is not acceptable as the
-name of a string, macro, diversion, number register, environment, or
-font.  It returns@tie{}0 if no argument is given.  This is useful for

-
-The other is an @dfn{escape} which can be usually embedded anywhere

-backslashes.  This is @emph{not} true for requests.
-
-Here are a few examples for a hypothetical macro @code{uh}:

-.uh The\ Mouse\ Problem
-@endExample
-
-@cindex @code{\~}, difference to @code{\@key{SP}}

-@noindent
-The first line is the @code{uh} macro being called with 3 arguments,
-@samp{The}, @samp{Mouse}, and @samp{Problem}.  The latter two have the
-same effect of calling the @code{uh} macro with one argument, @samp{The
-Mouse Problem}.@footnote{The last solution, i.e., using escaped spaces,
-is ``classical'' in the sense that it can be found in most @code{troff}
-documents.  Nevertheless, it is not optimal in all situations, since
-@w{@samp{\ }} inserts a fixed-width, non-breaking space character which
-can't stretch.  @code{gtroff} provides a different command @code{\~} to
-insert a stretchable, non-breaking space.}
-
-@cindex @code{"}, in a macro argument
-@cindex double quote, in a macro argument
-A double quote which isn't preceded by a space doesn't start a macro
-argument.  If not closing a string, it is printed literally.
-
-For example,
-
-@Example
-.xxx a" "b c" "de"fg"
-@endExample
-
-@noindent
-has the arguments @samp{a"}, @w{@samp{b c}}, @samp{de}, and @samp{fg"}.
-Don't rely on this obscure behaviour!
-
-There are two possibilities to get a double quote reliably.
-
-@itemize @bullet
-@item
-Enclose the whole argument with double quotes and use two consecutive double
-quotes to represent a single one.  This traditional solution has the
-disadvantage that double quotes don't survive argument expansion again if
-called in compatibility mode (using the @option{-C} option of @code{groff}):
-
-@Example
-.de xx
-.  tm xx: `\\$1' `\\$2' `\\$3'
-.
-.  yy "\\$1" "\\$2" "\\$3"
-..
-.de yy
-.  tm yy: `\\$1' `\\$2' `\\$3'
-..
-.xx A "test with ""quotes""" .
-    @result{} xx: `A' `test with "quotes"' `.'
-    @result{} yy: `A' `test with ' `quotes""'
-@endExample
-
-@noindent
-If not in compatibility mode, you get the expected result
-
-@Example
-xx: `A' `test with "quotes"' `.'
-yy: `A' `test with "quotes"' `.'
-@endExample
-
-@noindent
-since @code{gtroff} preserves the input level.
-
-@item
-Use the double quote glyph @code{\(dq}.  This works with and without
-compatibility mode enabled since @code{gtroff} doesn't convert @code{\(dq}
-back to a double quote input character.
-
-Not that this method won't work with @acronym{UNIX} @code{troff} in general
-since the glyph `dq' isn't defined normally.

-@subsection Escapes
-@cindex escapes
-
-Escapes may occur anywhere in the input to @code{gtroff}.  They usually
-begin with a backslash and are followed by a single character which
-indicates the function to be performed.  The escape character can be
-changed; see @ref{Character Translations}.
-
-Escape sequences which require an identifier as a parameter accept three
-possible syntax forms.
-
-@itemize @bullet
-@item
-The next single character is the identifier.
-
-@cindex @code{(}, starting a two-character identifier
-@item
-If this single character is an opening parenthesis, take the following
-two characters as the identifier.  Note that there is no closing
-parenthesis after the identifier.
-
-@cindex @code{[}, starting an identifier
-@cindex @code{]}, ending an identifier
-@item
-If this single character is an opening bracket, take all characters
-until a closing bracket as the identifier.

-@cindex @code{'}, delimiting arguments
-@cindex argument delimiting characters
-@cindex characters, argument delimiting
-@cindex delimiting characters for arguments
-Other escapes may require several arguments and/or some special format.
-In such cases the argument is traditionally enclosed in single quotes
-(and quotes are always used in this manual for the definitions of escape
-sequences).  The enclosed text is then processed according to what that
-escape expects.  Example:
-
-@Example
-\l'1.5i\(bu'
-@endExample
-
-@cindex @code{\o}, possible quote characters
-@cindex @code{\b}, possible quote characters
-@cindex @code{\X}, possible quote characters
-Note that the quote character can be replaced with any other character
-which does not occur in the argument (even a newline or a space
-character) in the following escapes: @code{\o}, @code{\b}, and
-@code{\X}.  This makes e.g.
-
-@Example
-A caf
-\o
-e\'
-
-
-in Paris
-  @result{} A café in Paris

-Probably one of the most@footnote{Unfortunately, this is a lie.  But

-common forms of escapes is the comment.
-
-@Defesc {\\", , , }
-Start a comment.  Everything to the end of the input line is ignored.

-This may sound simple, but it can be tricky to keep the comments from
-interfering with the appearance of the final output.
-
-@cindex @code{ds}, @code{ds1} requests, and comments
-@cindex @code{as}, @code{as1} requests, and comments
-If the escape is to the right of some text or a request, that portion
-of the line is ignored, but the space leading up to it is noticed by
-@code{gtroff}.  This only affects the @code{ds} and @code{as}
-request and its variants.
-
-@cindex tabs, before comments
-@cindex comments, lining up with tabs
-One possibly irritating idiosyncracy is that tabs must not be used to
-line up comments.  Tabs are not treated as whitespace between the
-request and macro arguments.
-
-@cindex undefined request
-@cindex request, undefined
-A comment on a line by itself is treated as a blank line, because
-after eliminating the comment, that is all that remains:
-
-@Example
-Test
-\" comment
-Test
-@endExample
-
-@noindent
-produces
-
-@Example
-Test
-
-Test
-@endExample
-
-To avoid this, it is common to start the line with @code{.\"} which
-causes the line to be treated as an undefined request and thus ignored
-completely.
-
-@cindex @code{'}, as a comment
-Another commenting scheme seen sometimes is three consecutive single
-quotes (@code{'''}) at the beginning of a line.  This works, but
-@code{gtroff} gives a warning about an undefined macro (namely
-@code{''}), which is harmless, but irritating.
-@endDefesc
-
-@Defesc {\\#, , , }
-To avoid all this, @code{gtroff} has a new comment mechanism using the
-@code{\#} escape.  This escape works the same as @code{\"} except that

-Test
-\# comment

-as expected.
-@endDefesc
-
-@Defreq {ig, [@Var{end}]}
-Ignore all input until @code{gtroff} encounters the macro named
-@code{.}@var{end} on a line by itself (or @code{..} if @var{end} is not
-specified).  This is useful for commenting out large blocks of text:
-
-@Example
-text text text...
-.ig
-This is part of a large block
-of text that has been
-temporarily(?) commented out.
-
-We can restore it simply by removing
-the .ig request and the ".." at the

-with a representation of that number.  This output format can be
-changed to a variety of formats (numbers, Roman numerals, etc.).  This
-is done using the @code{af} request.
-
-@Defreq {af, ident format}
-Change the output format of a number register.  The first argument
-@var{ident} is the name of the number register to be changed, and the
-second argument @var{format} is the output format.  The following
-output formats are available:
-
-@table @code
-@item 1
-Decimal arabic numbers.  This is the default format: 0, 1, 2,
-3,@tie{}@enddots{}
-
-@item 0@dots{}0
-Decimal numbers with as many digits as specified.  So, @samp{00} would
-result in printing numbers as 01, 02, 03,@tie{}@enddots{}
-
-In fact, any digit instead of zero will do; @code{gtroff} only counts
-how many digits are specified.  As a consequence, @code{af}'s default
-format @samp{1} could be specified as @samp{0} also (and exactly this is
-returned by the @code{\g} escape, see below).

-@cindex @code{trf} request, causing implicit linebreak
-Various ways of causing @dfn{breaks} were given in @ref{Implicit Line
-Breaks}.  The @code{br} request likewise causes a break.  Several
-other requests also cause breaks, but implicitly.  These are
-@code{bp}, @code{ce}, @code{cf}, @code{fi}, @code{fl}, @code{in},
-@code{nf}, @code{rj}, @code{sp}, @code{ti}, and @code{trf}.
-
-@Defreq {br, }
-Break the current line, i.e., the input collected so far is emitted
-without adjustment.
-
-If the no-break control character is used, @code{gtroff} suppresses
-the break:
-
-@Example
-a
-'br
-b
-    @result{} a b
-@endExample
-@endDefreq
-
-Initially, @code{gtroff} fills and adjusts text to both margins.
-Filling can be disabled via the @code{nf} request and re-enabled with
-the @code{fi} request.
-
-@DefreqList {fi, }
-@DefregListEnd {.u}
-@cindex fill mode (@code{fi})
-@cindex mode, fill (@code{fi})
-Activate fill mode (which is the default).  This request implicitly
-enables adjusting; it also inserts a break in the text currently being
-filled.  The read-only number register @code{.u} is set to@tie{}1.
-
-The fill mode status is associated with the current environment
-(@pxref{Environments}).
-
-See @ref{Line Control}, for interaction with the @code{\c} escape.
-@endDefreq
-
-@Defreq {nf, }
-@cindex no-fill mode (@code{nf})
-@cindex mode, no-fill (@code{nf})
-Activate no-fill mode.  Input lines are output as-is, retaining line
-breaks and ignoring the current line length.  This command implicitly
-disables adjusting; it also causes a break.  The number register
-@code{.u} is set to@tie{}0.
-
-The fill mode status is associated with the current environment
-(@pxref{Environments}).
-
-See @ref{Line Control}, for interaction with the @code{\c} escape.
-@endDefreq
-
-@DefreqList {ad, [@Var{mode}]}
-@DefregListEnd {.j}
-Set adjusting mode.
-
-Activation and deactivation of adjusting is done implicitly with
-calls to the @code{fi} or @code{nf} requests.
-
-@var{mode} can have one of the following values:
-
-@table @code
-@item l
-@cindex ragged-right
-Adjust text to the left margin.  This produces what is traditionally
-called ragged-right text.
-
-@item r
-@cindex ragged-left
-Adjust text to the right margin, producing ragged-left text.
-
-@item c
-@cindex centered text
-@cindex @code{ce} request, difference to @samp{.ad@tie{}c}
-Center filled text.  This is different to the @code{ce} request which
-only centers text without filling.
-
-@item b
-@itemx n
-Justify to both margins.  This is the default used by @code{gtroff}.
-@end table
-
-Finally, @var{mode} can be the numeric argument returned by the @code{.j}
-register.
-
-With no argument, @code{gtroff} adjusts lines in the same way it did
-before adjusting was deactivated (with a call to @code{na}, for
-example).
-
-@Example
-text
-.ad r
-.nr ad \n[.j]
-text
-.ad c

-text
-.ad         \" back to centering

-.ad \n[ad]  \" back to right justifying
-@endExample
-
-@cindex adjustment mode register (@code{.j})
-The current adjustment mode is available in the read-only number
-register @code{.j}; it can be stored and subsequently used to set
-adjustment.
-
-The adjustment mode status is associated with the current environment
-(@pxref{Environments}).
-@endDefreq
-
-@Defreq {na, }
-Disable adjusting.  This request won't change the current adjustment
-mode: A subsequent call to @code{ad} uses the previous adjustment
-setting.
-
-The adjustment mode status is associated with the current environment
-(@pxref{Environments}).
-@endDefreq
-
-@DefreqList {brp, }
-@DefescListEnd {\\p, , , }
-Adjust the current line and cause a break.
-
-In most cases this produces very ugly results since @code{gtroff}
-doesn't have a sophisticated paragraph building algorithm (as @TeX{}
-have, for example); instead, @code{gtroff} fills and adjusts a paragraph
-line by line:
-
-@Example
-  This is an uninteresting sentence.
-  This is an uninteresting sentence.\p
-  This is an uninteresting sentence.
-@endExample
-

-@cindex space between words register (@code{.ss})
-@cindex sentence space size register (@code{.sss})
-@cindex size of sentence space register (@code{.sss})
-@cindex space between sentences register (@code{.sss})
-Change the size of a space between words.  It takes its units as one
-twelfth of the space width parameter for the current font.
-Initially both the @var{word_space_size} and @var{sentence_space_size}
-are@tie{}12.  In fill mode, the values specify the minimum distance.
-
-@cindex fill mode
-@cindex mode, fill
-If two arguments are given to the @code{ss} request, the second
-argument sets the sentence space size.  If the second argument is not
-given, sentence space size is set to @var{word_space_size}.  The
-sentence space size is used in two circumstances: If the end of a
-sentence occurs at the end of a line in fill mode, then both an
-inter-word space and a sentence space are added; if two spaces follow
-the end of a sentence in the middle of a line, then the second space
-is a sentence space.  If a second argument is never given to the
-@code{ss} request, the behaviour of @acronym{UNIX} @code{troff} is the
-same as that exhibited by GNU @code{troff}.  In GNU @code{troff}, as
-in @acronym{UNIX} @code{troff}, a sentence should always be followed
-by either a newline or two spaces.
-
-The read-only number registers @code{.ss} and @code{.sss} hold the
-values of the parameters set by the first and second arguments of the
-@code{ss} request.
-
-The word space and sentence space values are associated with the current
-environment (@pxref{Environments}).
-
-Contrary to @acronym{AT&T} @code{troff}, this request is @emph{not}
-ignored if a TTY output device is used; the given values are then
-rounded down to a multiple of@tie{}12 (@pxref{Implementation Differences}).
-
-The request is ignored if there is no parameter.
-
-@cindex discardable horizontal space
-@cindex space, discardable, horizontal
-@cindex horizontal discardable space
-Another useful application of the @code{ss} request is to insert
-discardable horizontal space, i.e., space which is discarded at a line
-break.  For example, paragraph-style footnotes could be separated this
-way:
-
-@Example
-.ll 4.5i
-1.\ This is the first footnote.\c
-.ss 48
-.nop
-.ss 12
-2.\ This is the second footnote.
-@endExample
-
-@noindent
-The result:
-
-@Example
-1. This is the first footnote.        2. This
-is the second footnote.
-@endExample
-
-@noindent
-Note that the @code{\h} escape produces unbreakable space.
-@endDefreq
-
-@DefreqList {ce, [@Var{nnn}]}
-@DefregListEnd {.ce}
-@cindex centering lines (@code{ce})
-@cindex lines, centering (@code{ce})
-Center text.  While the @w{@samp{.ad c}} request also centers text,
-it fills the text as well.  @code{ce} does not fill the
-text it affects.  This request causes a break.  The number of lines
-still to be centered is associated with the current environment
-(@pxref{Environments}).
-
-The following example demonstrates the differences.
-Here the input:
-
-@Example
-.ll 4i
-.ce 1000
-This is a small text fragment which shows the differences
-between the `.ce' and the `.ad c' request.
-.ce 0
-
-.ad c
-This is a small text fragment which shows the differences
-between the `.ce' and the `.ad c' request.
-@endExample
-
-@noindent
-And here the result:
-
-@Example
-  This is a small text fragment which
-         shows the differences
-between the `.ce' and the `.ad c' request.
-
-  This is a small text fragment which
-shows the differences between the `.ce'
-        and the `.ad c' request.
-@endExample
-
-With no arguments, @code{ce} centers the next line of text.  @var{nnn}
-specifies the number of lines to be centered.  If the argument is zero
-or negative, centering is disabled.
-
-The basic length for centering text is the line length (as set with the
-@code{ll} request) minus the indentation (as set with the @code{in}
-request).  Temporary indentation is ignored.
-
-As can be seen in the previous example, it is a common idiom to turn
-on centering for a large number of lines, and to turn off centering
-after text to be centered.  This is useful for any request which takes
-a number of lines as an argument.
-
-The @code{.ce} read-only number register contains the number of lines
-remaining to be centered, as set by the @code{ce} request.
-@endDefreq

-@DefregListEnd {.rj}
-@cindex justifying text (@code{rj})
-@cindex text, justifying (@code{rj})
-@cindex right-justifying (@code{rj})
-Justify unfilled text to the right margin.  Arguments are identical to
-the @code{ce} request.  The @code{.rj} read-only number register is
-the number of lines to be right-justified as set by the @code{rj}
-request.  This request causes a break.  The number of lines still to be
-right-justified is associated with the current environment
-(@pxref{Environments}).

-
-Here a description of requests which influence hyphenation.
-
-@DefreqList {hy, [@Var{mode}]}
-@DefregListEnd {.hy}
-Enable hyphenation.  The request has an optional numeric argument,
-@var{mode}, to restrict hyphenation if necessary:

-@item 1
-The default argument if @var{mode} is omitted.  Hyphenate without

-Do not hyphenate the last two characters of a word.
-
-@item 8
-Do not hyphenate the first two characters of a word.
-@end table
-
-Values in the previous table are additive.  For example, the

-two nor the first two characters of a word.
-
-@cindex hyphenation restrictions register (@code{.hy})
-The current hyphenation restrictions can be found in the read-only

-
-The hyphenation mode is associated with the current environment

-@endDefreq
-
-@Defreq {nh, }
-Disable hyphenation (i.e., set the hyphenation mode to zero).  Note
-that the hyphenation mode of the last call to @code{hy} is not

-
-The hyphenation mode is associated with the current environment
-(@pxref{Environments}).

-Set the maximum number of consecutive hyphenated lines to @var{nnn}.
-If this number is negative, there is no maximum.  The default value
-is@tie{}@minus{}1 if @var{nnn} is omitted.  This value is associated
-with the current environment (@pxref{Environments}).  Only lines
-output from a given environment count towards the maximum associated
-with that environment.  Hyphens resulting from @code{\%} are counted;
-explicit hyphens are not.
-
-The current setting of @code{hlm} is available in the @code{.hlm}

-example:
-
-@Example
-.hw in-sa-lub-rious
-@endExample
-
-@noindent
-Besides the space character, any character whose hyphenation code value
-is zero can be used to separate the arguments of @code{hw} (see the

-In addition, this request can be used more than once.
-
-Hyphenation exceptions specified with the @code{hw} request are
-associated with the current hyphenation language; it causes an error
-if there is no current hyphenation language.
-
-This request is ignored if there is no parameter.

-To tell @code{gtroff} how to hyphenate words on the fly, use the
-@code{\%} escape, also known as the @dfn{hyphenation character}.
-Preceding a word with this character prevents it from being
-hyphenated; putting it inside a word indicates to @code{gtroff} that
-the word may be hyphenated at that point.  Note that this mechanism
-only affects that one occurrence of the word; to change the
-hyphenation of a word for the entire document, use the @code{hw}
-request.
-
-The @code{\:} escape inserts a zero-width break point
-(that is, the word breaks but without adding a hyphen).
-

-... check the /var/log/\:httpd/\:access_log file ...
-@endExample
-
-@cindex @code{\X}, followed by @code{\%}
-@cindex @code{\Y}, followed by @code{\%}
-@cindex @code{\%}, following @code{\X} or @code{\Y}
-Note that @code{\X} and @code{\Y} start a word, that is, the @code{\%}
-escape in (say) @w{@samp{\X'...'\%foobar}} and
-@w{@samp{\Y'...'\%foobar}} no longer prevents hyphenation but inserts
-a hyphenation point at the beginning of @samp{foobar}; most likely
-this isn't what you want to do.
-@endDefesc
-
-@Defreq {hc, [@Var{char}]}
-Change the hyphenation character to @var{char}.  This character then
-works the same as the @code{\%} escape, and thus, no longer appears in
-the output.  Without an argument, @code{hc} resets the hyphenation

-input character (not a special character) other than a digit or a
-space.
-
-To make hyphenation work, hyphenation codes must be set up.  At
-start-up, groff only assigns hyphenation codes to the letters
-@samp{a}-@samp{z} (mapped to themselves) and to the letters
-@samp{A}-@samp{Z} (mapped to @samp{a}-@samp{z}); all other hyphenation
-codes are set to zero.  Normally, hyphenation patterns contain only
-lowercase letters which should be applied regardless of case.  With
-other words, the words `FOO' and `Foo' should be hyphenated exactly the
-same way as the word `foo' is hyphenated, and this is what @code{hcode}
-is good for.  Words which contain other letters won't be hyphenated
-properly if the corresponding hyphenation patterns actually do contain
-them.  For example, the following @code{hcode} requests are necessary to
-assign hyphenation codes to the letters @samp{ÄäÖöÜüß} (this is needed
-for German):
-
-@Example
-.hcode ä ä  Ä ä
-.hcode ö ö  Ö ö
-.hcode ü ü  Ü ü

-@endExample
-
-Without those assignments, groff treats German words like
-@w{`Kindergärten'} (the plural form of `kindergarten') as two
-substrings @w{`kinderg'} and @w{`rten'} because the hyphenation code
-of the umlaut@tie{}a is zero by default.  There is a German
-hyphenation pattern which covers @w{`kinder'}, so groff finds the

-Change tab stop positions.  This request takes a series of tab
-specifiers as arguments (optionally divided into two groups with the
-letter @samp{T}) which indicate where each tab stop is to be
-(overriding any previous settings).
-
-Tab stops can be specified absolutely, i.e., as the distance from the
-left margin.  For example, the following sets 6@tie{}tab stops every
-one inch.
-
-@Example
-.ta 1i 2i 3i 4i 5i 6i
-@endExample
-
-Tab stops can also be specified using a leading @samp{+}
-which means that the specified tab stop is set relative to
-the previous tab stop.  For example, the following is equivalent to the
-previous example.
-
-@Example
-.ta 1i +1i +1i +1i +1i +1i
-@endExample
-
-@code{gtroff} supports an extended syntax to specify repeat values after
-the @samp{T} mark (these values are always taken as relative) -- this is
-the usual way to specify tabs set at equal intervals.  The following is,
-yet again, the same as the previous examples.  It does even more since
-it defines an infinite number of tab stops separated by one inch.
-
-@Example
-.ta T 1i
-@endExample
-
-Now we are ready to interpret the full syntax given at the beginning:
-Set tabs at positions @var{n1}, @var{n2}, @dots{}, @var{nn} and then set
-tabs at @var{nn}+@var{r1}, @var{nn}+@var{r2}, @dots{}, @var{nn}+@var{rn}
-and then at @var{nn}+@var{rn}+@var{r1}, @var{nn}+@var{rn}+@var{r2},
-@dots{}, @var{nn}+@var{rn}+@var{rn}, and so on.
-
-Example: @samp{4c +6c T 3c 5c 2c} is equivalent to @samp{4c 10c 13c 18c
-20c 23c 28c 30c @dots{}}.
-
-The material in each tab column (i.e., the column between two tab stops)
-may be justified to the right or left or centered in the column.  This
-is specified by appending @samp{R}, @samp{L}, or @samp{C} to the tab
-specifier.  The default justification is @samp{L}.  Example:
-
-@Example
-.ta 1i 2iC 3iR
-@endExample
-
-Some notes:
-
-@itemize @bullet
-@item
-The default unit of the @code{ta} request is @samp{m}.
-
-@item
-A tab stop is converted into a non-breakable horizontal movement which
-can be neither stretched nor squeezed.  For example,
-
-@Example
-.ds foo a\tb\tc
-.ta T 5i
-\*[foo]
-@endExample
-
-@noindent
-creates a single line which is a bit longer than 10@tie{}inches (a string
-is used to show exactly where the tab characters are).  Now consider the
-following:
-
-@Example
-.ds bar a\tb b\tc
-.ta T 5i
-\*[bar]
-@endExample
-
-@noindent
-@code{gtroff} first converts the tab stops of the line into unbreakable
-horizontal movements, then splits the line after the second @samp{b}
-(assuming a sufficiently short line length).  Usually, this isn't what
-the user wants.
-
-@item
-Superfluous tabs (i.e., tab characters which do not correspond to a tab
-stop) are ignored except the first one which delimits the characters
-belonging to the last tab stop for right-justifying or centering.
-Consider the following example
-
-@Example
-.ds Z   foo\tbar\tfoo
-.ds ZZ  foo\tbar\tfoobar
-.ds ZZZ foo\tbar\tfoo\tbar
-.ta 2i 4iR
-\*[Z]
-.br
-\*[ZZ]
-.br
-\*[ZZZ]
-.br
-@endExample
-
-@noindent
-which produces the following output:
-
-@Example
-foo                 bar              foo
-foo                 bar           foobar
-foo                 bar              foobar
-@endExample
-
-@noindent
-The first line right-justifies the second `foo' relative to the tab
-stop.  The second line right-justifies `foobar'.  The third line finally
-right-justifies only `foo' because of the additional tab character which
-marks the end of the string belonging to the last defined tab stop.

-The width of a field is the distance on the @emph{input} line from the

-character inserts stretchable space similar to @TeX{}'s @code{\hss}

-@cindex @code{\}, disabling (@code{eo})
-Disable the escape mechanism completely.  After executing this
-request, the backslash character @samp{\} no longer starts an escape
-sequence.
-
-This request can be very helpful in writing macros since it is not
-necessary then to double the escape character.  Here an example:
-
-@Example
-.\" This is a simplified version of the
-.\" .BR request from the man macro package
-.eo
-.de BR
-.  ds result \&
-.  while (\n[.$] >= 2) \@{\
-.    as result \fB\$1\fR\$2
-.    shift 2
-.  \@}
-.  if \n[.$] .as result \fB\$1
-\*[result]
-.  ft R
-..
-.ec
-@endExample
-@endDefreq
-
-@Defreq {ec, [@Var{c}]}
-@cindex escape character, changing (@code{ec})
-@cindex character, escape, changing (@code{ec})
-Set the escape character to@tie{}@var{c}.  With no argument the default
-escape character @samp{\} is restored.  It can be also used to
-re-enable the escape mechanism after an @code{eo} request.
-
-Note that changing the escape character globally will likely break
-macro packages since @code{gtroff} has no mechanism to `intern' macros,
-i.e., to convert a macro definition into an internal form which is
-independent of its representation (@TeX{} has this mechanism).
-If a macro is called, it is executed literally.
-@endDefreq
-
-@DefreqList {ecs, }
-@DefreqListEnd {ecr, }
-The @code{ecs} request saves the current escape character
-in an internal register.
-Use this request in combination with the @code{ec} request to
-temporarily change the escape character.
-
-The @code{ecr} request restores the escape character
-saved with @code{ecs}.
-Without a previous call to @code{ecs}, this request
-sets the escape character to @code{\}.
-@endDefreq
-
-@DefescList {\\\\, , , }
-@DefescItem {\\e, , , }
-@DefescListEnd {\\E, , , }
-Print the current escape character (which is the backslash character
-@samp{\} by default).
-
-@code{\\} is a `delayed' backslash; more precisely, it is the default
-escape character followed by a backslash, which no longer has special
-meaning due to the leading escape character.  It is @emph{not} an escape
-sequence in the usual sense!  In any unknown escape sequence
-@code{\@var{X}} the escape character is ignored and @var{X} is printed.
-But if @var{X} is equal to the current escape character, no warning is
-emitted.
-
-As a consequence, only at top-level or in a diversion a backslash glyph is
-printed; in copy-in mode, it expands to a single backslash which then
-combines with the following character to an escape sequence.
-
-The @code{\E} escape differs from @code{\e} by printing an escape
-character that is not interpreted in copy mode.
-Use this to define strings with escapes that work
-when used in copy mode (for example, as a macro argument).
-The following example defines strings to begin and end
-a superscript:
-
-@Example
-.ds @{ \v'-.3m'\s'\En[.s]*60/100'
-.ds @} \s0\v'.3m'
-@endExample
-
-Another example to demonstrate the differences between the various escape
-sequences, using a strange escape character, @samp{-}.
-
-@Example
-.ec -
-.de xxx
---A'123'
-..
-.xxx
-    @result{} -A'foo'
-@endExample
-
-@noindent
-The result is surprising for most users, expecting @samp{1} since
-@samp{foo} is a valid identifier.  What has happened?  As mentioned
-above, the leading escape character makes the following character
-ordinary.  Written with the default escape character the sequence
-@samp{--} becomes @samp{\-} -- this is the minus sign.
-
-If the escape character followed by itself is a valid escape sequence,
-only @code{\E} yields the expected result:
-
-@Example
-.ec -
-.de xxx
--EA'123'
-..
-.xxx
-    @result{} 1
-@endExample
-@endDefesc
-
-@Defesc {\\., , , }
-Similar to @code{\\}, the sequence @code{\.} isn't a real escape sequence.
-As before, a warning message is suppressed if the escape character is
-followed by a dot, and the dot itself is printed.
-
-@Example
-.de foo
-.  nop foo
-.
-.  de bar
-.    nop bar
-\\..
-.
-..
-.foo
-.bar
-    @result{} foo bar
-@endExample
-
-@noindent
-The first backslash is consumed while the macro is read, and the second
-is swallowed while exexuting macro @code{foo}.
-@endDefesc
-
-A @dfn{translation} is a mapping of an input character to an output
-glyph.  The mapping occurs at output time, i.e., the input character
-gets assigned the metric information of the mapped output character
-right before input tokens are converted to nodes (@pxref{Gtroff
-Internals}, for more on this process).
-
-@DefreqList {tr, @Var{a}@Var{b}@Var{c}@Var{d}@dots{}}

-Translate character @var{a} to glyph@tie{}@var{b}, character @var{c} to
-glyph@tie{}@var{d}, etc.  If there is an odd number of arguments, the
-last one is translated to an unstretchable space (@w{@samp{\ }}).
-
-The @code{trin} request is identical to @code{tr},
-but when you unformat a diversion with @code{asciify}
-it ignores the translation.

-The pair @samp{@var{c}\&} (this is an arbitrary character@tie{}@var{c}

-It is even possible to map the space character to nothing:

-@noindent
-As shown in the example, the space character can't be the first

-not possible to map the space character to any other glyph; requests
-like @w{@samp{.tr aa x}} undo @w{@samp{.tr aa \&}} instead.
-
-If justification is active, lines are justified in spite of the
-`empty' space character (but there is no minimal distance, i.e.@: the

-
-@item
-After an output glyph has been constructed (this happens at the
-moment immediately before the glyph is appended to an output
-glyph list, either by direct output, in a macro, diversion, or
-string), it is no longer affected by @code{tr}.
-
-@item
-Translating character to glyphs where one of them or both are

-
-@item
-@code{troff} no longer has a hard-coded dependency on @w{Latin-1};

-if the @code{tr} request isn't handled properly.
-
-Consider the following translation:
-
-@Example
-.tr éÉ
-@endExample
-
-@noindent
-This maps input character @code{é} onto glyph @code{É}, which is
-identical to glyph @code{char201}.  But this glyph intentionally
-doesn't exist!  Instead, @code{\[char201]} is treated as an input
-character entity and is by default mapped onto @code{\['E]}, and
-@code{gtroff} doesn't handle translations of translations.
-
-The right way to write the above translation is
-
-@Example
-.tr é\['E]
-@endExample
-
-@noindent
-With other words, the first argument of @code{tr} should be an input
-character or entity, and the second one a glyph entity.

-Originally, @code{nroff} and @code{troff} were two separate programs,
-the former for TTY output, the latter for everything else.  With GNU
-@code{troff}, both programs are merged into one executable, sending
-its output to a device driver (@code{grotty} for TTY devices,
-@code{grops} for @sc{PostScript}, etc.) which interprets the
-intermediate output of @code{gtroff}.  For @acronym{UNIX} @code{troff}
-it makes sense to talk about @dfn{Nroff mode} and @dfn{Troff mode}
-since the differences are hardcoded.  For GNU @code{troff}, this
-distinction is not appropriate because @code{gtroff} simply takes the
-information given in the font files for a particular device without
-handling requests specially if a TTY output device is used.
-
-Usually, a macro package can be used with all output devices.
-Nevertheless, it is sometimes necessary to make a distinction between
-TTY and non-TTY devices: @code{gtroff} provides two built-in
-conditions @samp{n} and @samp{t} for the @code{if}, @code{ie}, and

-@noindent
-In the above example, @samp{|0} specifies a negative distance from the

-
-@DefescList {\\@key{RET}, , ,}

-@DefregListEnd{.int}
-Continue a line.  @code{\@key{RET}} (this is a backslash at the end

-    @result{} This is a .test
-@endExample
-
-The @samp{|} operator is also affected.
-
-@cindex @code{\R}, after @code{\c}
-@code{\c} works on the output level.  Anything after this escape on the
-same line is ignored, except @code{\R} which works as usual.  Anything
-before @code{\c} on the same line will be appended to the current partial

-@cindex page number character (@code{%})
-Print a @dfn{title line}.  It consists of three parts: a left

-The argument separator @samp{'} can be replaced with any character not
-occurring in the title line.  The @samp{%} character is replaced with

-
-Without argument, @code{tl} is ignored.
-
-Some notes:
-
-@itemize @bullet
-@item
-A title line is not restricted to the top or bottom of a page.
-
-@item
-@code{tl} prints the title line immediately, ignoring a partially filled
-line (which stays untouched).
-
-@item
-It is not an error to omit closing delimiters.  For example,
-@w{@samp{.tl /foo}} is equivalent to @w{@samp{.tl /foo///}}: It prints a
-title line with the left justified word @samp{foo}; the centered and

-@cindex positions, font
-
-For the sake of old phototypesetters and compatibility with old versions
-of @code{troff}, @code{gtroff} has the concept of font @dfn{positions},
-on which various fonts are mounted.
-
-@DefreqList {fp, pos font [@Var{external-name}]}
-@DefregItem {.f}
-@DefregListEnd {.fp}
-@cindex mounting font (@code{fp})
-@cindex font, mounting (@code{fp})
-Mount font @var{font} at position @var{pos} (which must be a
-non-negative integer).  This numeric position can then be referred to
-with font changing commands.  When @code{gtroff} starts it is using
-font position@tie{}1 (which must exist; position@tie{}0 is unused
-usually at start-up).
-
-@cindex font position register (@code{.f})
-The current font in use, as a font position, is available in the
-read-only number register @samp{.f}.  This can be useful to remember the
-current font for later recall.  It is associated with the current
-environment (@pxref{Environments}).
-
-@Example
-.nr save-font \n[.f]
-.ft B
-... text text text ...
-.ft \n[save-font]
-@endExample
-
-@cindex next free font position register (@code{.fp})
-The number of the next free font position is available in the read-only
-number register @samp{.fp}.  This is useful when mounting a new font,
-like so:
-
-@Example
-.fp \n[.fp] NEATOFONT
-@endExample
-
-@pindex DESC@r{, and font mounting}
-Fonts not listed in the @file{DESC} file are automatically mounted on
-the next available font position when they are referenced.  If a font
-is to be mounted explicitly with the @code{fp} request on an unused
-font position, it should be mounted on the first unused font position,
-which can be found in the @code{.fp} register.  Although @code{gtroff}
-does not enforce this strictly, it is not allowed to mount a font at a
-position whose number is much greater (approx.@: 1000 positions) than
-that of any currently used position.
-
-The @code{fp} request has an optional third argument.  This argument
-gives the external name of the font, which is used for finding the font
-description file.  The second argument gives the internal name of the
-font which is used to refer to the font in @code{gtroff} after it has
-been mounted.  If there is no third argument then the internal name is
-used as the external name.  This feature makes it possible to use
-fonts with long names in compatibility mode.
-@endDefreq

-
-If @var{nnn} is associated with a style (as set with the @code{sty}

-it within the current font family (as set with the @code{fam} request,
-the @code{\F} escape, or with the @code{family} command in the @file{DESC}
-file).

-A @dfn{glyph} is a graphical representation of a @dfn{character}.
-While a character is an abstract entity containing semantic
-information, a glyph is something which can be actually seen on screen
-or paper.  It is possible that a character has multiple glyph
-representation forms (for example, the character `A' can be either
-written in a roman or an italic font, yielding two different glyphs);
-sometimes more than one character maps to a single glyph (this is a
-@dfn{ligature} -- the most common is `fi').

-@kindex fonts
-@pindex DESC
-@cindex @code{special} request, and glyph search order
-@cindex @code{fspecial} request, and glyph search order
-A @dfn{symbol} is simply a named glyph.  Within @code{gtroff}, all
-glyph names of a particular font are defined in its font file.  If the
-user requests a glyph not available in this font, @code{gtroff} looks
-up an ordered list of @dfn{special fonts}.  By default, the
-@sc{PostScript} output device supports the two special fonts @samp{SS}
-(slanted symbols) and @samp{S} (symbols) (the former is looked up
-before the latter).  Other output devices use different names for
-special fonts.  Fonts mounted with the @code{fonts} keyword in the
-@file{DESC} file are globally available.  To install additional
-special fonts locally (i.e.@: for a particular font), use the
-@code{fspecial} request.
-
-Here the exact rules how @code{gtroff} searches a given symbol:
-
-@itemize @bullet
-@item
-If the symbol has been defined with the @code{char} request, use it.
-This hides a symbol with the same name in the current font.
-
-@item
-Check the current font.
-

-
-@Example
-fonts 3 0 0 FOO
-@endExample
-
-@noindent
-This mounts font @code{foo} at font position@tie{}3.  We assume that
-@code{FOO} is a special font, containing glyph @code{foo},
-and that no font has been loaded yet.  The line
-
-@Example
-.fspecial BAR BAZ
-@endExample
-
-@noindent
-makes font @code{BAZ} special only if font @code{BAR} is active.  We
-further assume that @code{BAZ} is really a special font, i.e., the font
-description file contains the @code{special} keyword, and that it
-also contains glyph @code{foo} with a special shape fitting to font
-@code{BAR}.  After executing @code{fspecial}, font @code{BAR} is loaded at
-font position@tie{}1, and @code{BAZ} at position@tie{}2.
-
-We now switch to a new font @code{XXX}, trying to access glyph @code{foo}
-which is assumed to be missing.  There are neither font-specific special
-fonts for @code{XXX} nor any other fonts made special with the
-@code{special} request, so @code{gtroff} starts the search for special
-fonts in the list of already mounted fonts, with increasing font
-positions.  Consequently, it finds @code{BAZ} before @code{FOO} even for
-@code{XXX} which is not the intended behaviour.

-uppercase hexadecimal digit.  Examples: @code{u1234}, @code{u008E},
-@code{u12DB8}.  The largest Unicode value is 0x10FFFF.  There must be at
-least four @code{X} digits; if necessary, add leading zeroes (after the
-@samp{u}).  No zero padding is allowed for character codes greater than
-0xFFFF.  Surrogates (i.e., Unicode values greater than 0xFFFF

-@end display
-
-@noindent
-Example: @code{u0045_0302_0301}.
-
-For simplicity, all Unicode characters which are composites must be
-decomposed maximally (this is normalization form@tie{}D in the Unicode
-standard); for example, @code{u00CA_0301} is not a valid glyph name
-since U+00CA (@sc{latin capital letter e with circumflex}) can be
-further decomposed into U+0045 (@sc{latin capital letter e}) and U+0302
-(@sc{combining circumflex accent}).  @code{u0045_0302_0301} is thus the
-glyph name for U+1EBE, @sc{latin capital letter e with circumflex and
-acute}.
-
-@item
-groff maintains a table to decompose all algorithmically derived glyph
-names which are composites itself.  For example, @code{u0100} (@sc{latin
-letter a with macron}) will be automatically decomposed into
-@code{u0041_0304}.  Additionally, a glyph name of the GGL is preferred
-to an algorithmically derived glyph name; groff also automatically does
-the mapping.  Example: The glyph @code{u0045_0302} will be mapped to
-@code{^E}.
-
-@item
-glyph names of the GGL can't be used in composite glyph names; for
-example, @code{^E_u0301} is invalid.

-Insert a symbol @var{name} (two-character name @var{nm}) or a composite
-glyph with component glyphs @var{component1}, @var{component2},
-@enddots{} There is no special syntax for one-character names -- the
-natural form @samp{\@var{n}} would collide with escapes.@footnote{Note
-that a one-character symbol is not the same as an input character, i.e.,
-the character @code{a} is not the same as @code{\[a]}.  By default,
-@code{groff} defines only a single one-character symbol, @code{\[-]}; it
-is usually accessed as @code{\-}.  On the other hand, @code{gtroff} has
-the special feature that @code{\[char@var{XXX}]} is the same as the
-input character with character code @var{XXX}.  For example,
-@code{\[char97]} is identical to the letter @code{a} if @acronym{ASCII}

-
-If @var{name} is undefined, a warning of type @samp{char} is generated,

-follows:
-
-@itemize @bullet
-@item
-Any component which is found in the GGL will be converted to the
-@code{u@var{XXXX}} form.
-
-@item
-Any component @code{u@var{XXXX}} which is found in the list of
-decomposable glyphs will be decomposed.
-
-@item
-The resulting elements are then concatenated with @samp{_} inbetween,
-dropping the leading @samp{u} in all elements but the first.
-@end itemize
-
-No check for the existence of any component (similar to @code{tr}
-request) will be done.
-
-Examples:
-
-@table @code
-@item \[A ho]
-@samp{A} maps to @code{u0041}, @samp{ho} maps to @code{u02DB}, thus the
-final glyph name would be @code{u0041_02DB}.  Note this is not the
-expected result: The ogonek glyph @samp{ho} is a spacing ogonek, but for
-a proper composite a non-spacing ogonek (U+0328) is necessary.  Looking
-into the file @file{composite.tmac} one can find @w{@samp{.composite ho
-u0328}} which changes the mapping of @samp{ho} while a composite glyph
-name is constructed, causing the final glyph name to be
-@code{u0041_0328}.
-
-@item \[^E u0301]
-@itemx \[^E aa]
-@itemx \[E a^ aa]
-@itemx \[E ^ ']
-@samp{^E} maps to @code{u0045_0302}, thus the final glyph name is
-@code{u0045_0302_0301} in all forms (assuming proper calls of the

-@end table

-Default scaling indicator is @samp{z}.
-
-The read-only number register @code{.height} contains the font height as
-set by @code{\H}.
-
-Currently, only the @option{-Tps} device supports this feature.

-@cindex kerning and ligatures
-
-Ligatures are groups of characters that are run together, i.e, producing
-a single glyph.  For example, the letters `f' and `i' can form a
-ligature `fi' as in the word `file'.  This produces a cleaner look
-(albeit subtle) to the printed output.  Usually, ligatures are not
-available in fonts for TTY output devices.
-
-Most @sc{PostScript} fonts support the fi and fl ligatures.  The C/A/T
-typesetter that was the target of @acronym{AT&T} @code{troff} also
-supported `ff', `ffi', and `ffl' ligatures.  Advanced typesetters or
-`expert' fonts may include ligatures for `ft' and `ct', although GNU
-@code{troff} does not support these (yet).
-
-Only the current font is checked for ligatures and kerns; neither special
-fonts nor entities defined with the @code{char} request (and its siblings)
-are taken into account.

-The current ligature mode can be found in the read-only number register

-@cindex spacing, vertical
-@code{gtroff} uses two dimensions with each line of text, type size
-and vertical spacing.  The @dfn{type size} is approximately the height
-of the tallest glyph.@footnote{This is usually the parenthesis.
-Note that in most cases the real dimensions of the glyphs in a font
-are @emph{not} related to its type size!  For example, the standard
-@sc{PostScript} font families `Times Roman', `Helvetica', and
-`Courier' can't be used together at 10@dmn{pt}; to get acceptable
-output, the size of `Helvetica' has to be reduced by one point, and
-the size of `Courier' must be increased by one point.}  @dfn{Vertical
-spacing} is the amount of space @code{gtroff} allows for a line of
-text; normally, this is about 20%@tie{}larger than the current type
-size.  Ratios smaller than this can result in hard-to-read text;
-larger than this, it spreads the text out more vertically (useful for

-A @dfn{scaled point} is equal to @math{1/@var{sizescale}} points,
-where @var{sizescale} is specified in the @file{DESC} file (1@tie{}by
-default).  There is a new scale indicator @samp{z} which has the
-effect of multiplying by @var{sizescale}.  Requests and escape
-sequences in @code{gtroff} interpret arguments that represent a point
-size as being in units of scaled points, but they evaluate each such
-argument using a default scale indicator of @samp{z}.  Arguments
-treated in this way are the argument to the @code{ps} request, the
-third argument to the @code{cs} request, the second and fourth
-arguments to the @code{tkf} request, the argument to the @code{\H}
-escape sequence, and those variants of the @code{\s} escape sequence
-that take a numeric expression as their argument (see below).
-
-For example, suppose @var{sizescale} is@tie{}1000; then a scaled point
-is equivalent to a millipoint; the request @w{@samp{.ps 10.25}} is
-equivalent to @w{@samp{.ps 10.25z}} and thus sets the point size to
-10250@tie{}scaled points, which is equal to 10.25@tie{}points.
-
-@code{gtroff} disallows the use of the @samp{z} scale indicator in
-instances where it would make no sense, such as a numeric
-expression whose default scale indicator was neither @samp{u} nor
-@samp{z}.  Similarly it would make
-no sense to use a scaling indicator other than @samp{z} or @samp{u} in a
-numeric expression whose default scale indicator was @samp{z}, and so
-@code{gtroff} disallows this as well.
-
-There is also new scale indicator @samp{s} which multiplies by the
-number of units in a scaled point.  So, for example, @samp{\n[.ps]s} is
-equal to @samp{1m}.  Be sure not to confuse the @samp{s} and @samp{z}

-name@tie{}@var{n}, two-character name @var{nm}).  If @var{name} already
-exists, @code{ds} overwrites the previous definition.  Only the syntax form
-using brackets can take arguments which are handled identically to
-macro arguments; the single exception is that a closing bracket as an
-argument must be enclosed in double quotes.  @xref{Request and Macro
-Arguments}, and @ref{Parameters}.
-
-Example:
-
-@Example
-.ds foo a \\$1 test
-.
-This is \*[foo nice].
-    @result{} This is a nice test.
-@endExample
-
-The @code{\*} escape @dfn{interpolates} (expands in-place) a
-previously-defined string variable.  To be more precise, the stored
-string is pushed onto the input stack which is then parsed by
-@code{gtroff}.  Similar to number registers, it is possible to nest
-strings, i.e. string variables can be called within string variables.
-
-If the string named by the @code{\*} escape does not exist, it is
-defined as empty, and a warning of type @samp{mac} is emitted (see
-@ref{Debugging}, for more details).
-
-@cindex comments, with @code{ds}
-@cindex @code{ds} request, and comments
-@strong{Caution:} Unlike other requests, the second argument to the
-@code{ds} request takes up the entire line including trailing spaces.
-This means that comments on a line with such a request can introduce
-unwanted space into a string.
-
-@Example
-.ds UX \s-1UNIX\s0\u\s-3tm\s0\d \" UNIX trademark
-@endExample
-
-@noindent
-Instead the comment should be put on another line or have the comment
-escape adjacent with the end of the string.
-
-@Example
-.ds UX \s-1UNIX\s0\u\s-3tm\s0\d\"  UNIX trademark
-@endExample
-
-@cindex trailing quotes
-@cindex quotes, trailing
-@cindex leading spaces with @code{ds}
-@cindex spaces with @code{ds}
-@cindex @code{ds} request, and leading spaces
-To produce leading space the string can be started with a double
-quote.  No trailing quote is needed; in fact, any trailing quote is
-included in your string.
-
-@Example
-.ds sign "           Yours in a white wine sauce,

-@cindex multi-line strings
-@cindex strings, multi-line
-@cindex newline character, in strings, escaping
-@cindex escaping newline characters, in strings
-Strings are not limited to a single line of text.  A string can span
-several lines by escaping the newlines with a backslash.  The
-resulting string is stored @emph{without} the newlines.
-
-@Example
-.ds foo lots and lots \
-of text are on these \
-next several lines
-@endExample
-
-It is not possible to have real newlines in a string.  To put a single
-double quote character into a string, use two consecutive double quote
-characters.
-
-The @code{ds1} request turns off compatibility mode
-while interpreting a string.  To be more precise, a @dfn{compatibility
-save} input token is inserted at the beginning of  the string, and a
-@dfn{compatibility restore} input token at the end.
-
-@Example
-.nr xxx 12345
-.ds aa The value of xxx is \\n[xxx].
-.ds1 bb The value of xxx ix \\n[xxx].
-.
-.cp 1
-.
-\*(aa
-    @result{} warning: number register `[' not defined
-    @result{} The value of xxx is 0xxx].
-\*(bb

-@cindex common name space of macros, diversions, and strings
-@cindex macros, shared name space with strings and diversions
-@cindex strings, shared name space with macros and diversions
-@cindex diversions, shared name space with macros and strings
-Strings, macros, and diversions (and boxes) share the same name space.
-Internally, even the same mechanism is used to store them.  This has
-some interesting consequences.  For example, it is possible to call a
-macro with string syntax and vice versa.
-
-@Example
-.de xxx
-a funny test.
-..
-This is \*[xxx]
-    @result{} This is a funny test.
-
-.ds yyy a funny test
-This is
-.yyy
-    @result{} This is a funny test.
-@endExample
-
-Diversions and boxes can be also called with string syntax.
-
-Another consequence is that you can copy one-line diversions or boxes
-to a string.
-
-@Example
-.di xxx
-a \fItest\fR
-.br
-.di
-.ds yyy This is \*[xxx]\c
-\*[yyy].
-    @result{} @r{This is a }@i{test}.
-@endExample
-
-@noindent
-As the previous example shows, it is possible to store formatted
-output in strings.  The @code{\c} escape prevents the insertion of an
-additional blank line in the output.
-
-Copying diversions longer than a single output line produces
-unexpected results.
-
-@Example
-.di xxx
-a funny
-.br
-test
-.br
-.di
-.ds yyy This is \*[xxx]\c
-\*[yyy].
-    @result{} test This is a funny.
-@endExample
-
-Usually, it is not predictable whether a diversion contains one or
-more output lines, so this mechanism should be avoided.  With
-@acronym{UNIX} @code{troff}, this was the only solution to strip off a
-final newline from a diversion.  Another disadvantage is that the
-spaces in the copied string are already formatted, making them
-unstretchable.  This can cause ugly results.

-A clean solution to this problem is available in GNU @code{troff},
-using the requests @code{chop} to remove the final newline of a
-diversion, and @code{unformat} to make the horizontal spaces
-stretchable again.
-
-@Example
-.box xxx

-in the string has index@tie{}0.  If @var{n2} is omitted, it is taken to
-be equal to the string's length.  If the index value @var{n1} or
-@var{n2} is negative, it is counted from the end of the

-In @code{if} and @code{while} requests, there are several more
-operators available:
-
-@table @code
-@item e
-@itemx o
-True if the current page is even or odd numbered (respectively).
-
-@item n
-True if the document is being processed in nroff mode (i.e., the

-
-@item t
-True if the document is being processed in troff mode (i.e., the
-@code{.troff} command has been issued).
-
-@item v
-Always false.  This condition is for compatibility with other
-@code{troff} versions only (identifying a @code{-Tversatec} device).
-
-@item '@var{xxx}'@var{yyy}'
-True if the string @var{xxx} is equal to the string @var{yyy}.  Other
-characters can be used in place of the single quotes; the same set of
-delimiters as for the @code{\D} escape is used (@pxref{Escapes}).
-@code{gtroff} formats the strings before being compared:
-
-@Example
-.ie "|"\fR|\fP" \
-true
-.el \
-false
-    @result{} true
-@endExample
-
-@noindent
-The resulting motions, glyph sizes, and fonts have to
-match,@footnote{The created output nodes must be identical.
-@xref{Gtroff Internals}.} and not the individual motion, size, and
-font requests.  In the previous example, @samp{|} and @samp{\fR|\fP}
-both result in a roman @samp{|} glyph with the same point size and
-at the same location on the page, so the strings are equal.  If
-@samp{.ft@tie{}I} had been added before the @samp{.ie}, the result
-would be ``false'' because (the first) @samp{|} produces an italic
-@samp{|} rather than a roman one.
-
-@item r @var{xxx}
-True if there is a number register named @var{xxx}.
-
-@item d @var{xxx}
-True if there is a string, macro, diversion, or request named @var{xxx}.
-
-@item m @var{xxx}
-True if there is a color named @var{xxx}.
-
-@item c @var{g}
-True if there is a glyph @var{g} available@footnote{The name of this
-conditional operator is a misnomer since it tests names of output
-glyphs.}; @var{g} is either an @acronym{ASCII} character or a special
-character (@code{\(@var{gg}} or @code{\[@var{ggg}]}); the condition
-is also true if @var{g} has been defined by the @code{char} request.
-
-@item F @var{font}
-True if a font named @var{font} exists.  @var{font} is handled as if it was
-opened with the @code{ft} request (this is, font translation and styles are
-applied), without actually mounting it.
-
-This test doesn't load the complete font but only its header to verify
-its validity.
-
-@item S @var{style}
-True if style @var{style} has been registered.  Font translation is applied.
-@end table
-
-Note that these operators can't be combined with other operators like
-@samp{:} or @samp{&}; only a leading @samp{!} (without whitespace
-between the exclamation mark and the operator) can be used to negate
-the result.
-
-@Example
-.nr xxx 1
-.ie !r xxx \
-true
-.el \
-false
-    @result{} false
-@endExample
-
-A whitespace after @samp{!} always evaluates to zero (this bizarre

-.ie ! r xxx \
-true
-.el \

-Some remarks.
-
-@cindex @code{de} request, and @code{while}
-@itemize @bullet
-@item
-The body of a @code{while} request is treated like the body of a
-@code{de} request: @code{gtroff} temporarily stores it in a macro
-which is deleted after the loop has been exited.  It can considerably
-slow down a macro if the body of the @code{while} request (within the
-macro) is large.  Each time the macro is executed, the @code{while}
-body is parsed and stored again as a temporary macro.
-
-@Example
-.de xxx
-.  nr num 10
-.  while (\\n[num] > 0) \@{\
-.    \" many lines of code
-.    nr num -1
-.  \@}
-..
-@endExample
-
-@cindex recursive macros
-@cindex macros, recursive
-@noindent
-The traditional and ofter better solution (@acronym{UNIX} @code{troff}
-doesn't have the @code{while} request) is to use a recursive macro
-instead which is parsed only once during its definition.
-
-@Example
-.de yyy
-.  if (\\n[num] > 0) \@{\
-.    \" many lines of code
-.    nr num -1
-.    yyy
-.  \@}
-..
-.
-.de xxx
-.  nr num 10
-.  yyy
-..
-@endExample
-
-@noindent
-Note that the number of available recursion levels is set to@tie{}1000
-(this is a compile-time constant value of @code{gtroff}).
-
-@item
-The closing brace of a @code{while} body must end a line.
-
-@Example
-.if 1 \@{\
-.  nr a 0 1

-
-A @dfn{macro} is a collection of text and embedded commands which can
-be invoked multiple times.  Use macros to define common operations.
-
-@DefreqList {de, name [@Var{end}]}
-@DefreqItem {de1, name [@Var{end}]}
-@DefreqItem {dei, name [@Var{end}]}
-@DefreqListEnd {dei1, name [@Var{end}]}
-Define a new macro named @var{name}.  @code{gtroff} copies subsequent
-lines (starting with the next one) into an internal buffer until it
-encounters the line @samp{..} (two dots).  The optional second
-argument to @code{de} changes this to a macro to @samp{.@var{end}}.
-
-There can be whitespace after the first dot in the line containing the
-ending token (either @samp{.} or macro @samp{@var{end}}).
-
-Here a small example macro called @samp{P} which causes a break and
-inserts some vertical space.  It could be used to separate paragraphs.
-
-@Example
-.de P
-.  br
-.  sp .8v
-..
-@endExample
-
-The following example defines a macro within another.  Remember that
-expansion must be protected twice; once for reading the macro and
-once for executing.
-
-@Example
-\# a dummy macro to avoid a warning
-.de end
-..
-.
-.de foo
-.  de bar end
-.    nop \f[B]Hallo \\\\$1!\f[]
-.  end
-..
-.
-.foo
-.bar Joe
-    @result{} @b{Hallo Joe!}
-@endExample
-
-@noindent
-Since @code{\f} has no expansion, it isn't necessary to protect its
-backslash.  Had we defined another macro within @code{bar} which takes
-a parameter, eight backslashes would be necessary before @samp{$1}.
-
-The @code{de1} request turns off compatibility mode
-while executing the macro.  On entry, the current compatibility mode
-is saved and restored at exit.
-
-@Example
-.nr xxx 12345
-.
-.de aa
-The value of xxx is \\n[xxx].
-..
-.de1 bb
-The value of xxx ix \\n[xxx].
-..
-.
-.cp 1
-.
-.aa
-    @result{} warning: number register `[' not defined
-    @result{} The value of xxx is 0xxx].
-.bb
-    @result{} The value of xxx ix 12345.
-@endExample
-
-The @code{dei} request defines a macro indirectly.
-That is, it expands strings whose names
-are @var{name} or @var{end} before performing the append.
-
-This:
-
-@Example
-.ds xx aa
-.ds yy bb
-.dei xx yy
-@endExample
-
-@noindent
-is equivalent to:
-
-@Example
-.de aa bb
-@endExample
-
-The @code{dei1} request is similar to @code{dei} but with compatibility
-mode switched off during execution of the defined macro.
-
-If compatibility mode is on, @code{de} (and @code{dei}) behave similar to
-@code{de1} (and @code{dei1}): A `compatibility save' token is inserted at
-the beginning, and a `compatibility restore' token at the end, with
-compatibility mode switched on during execution.  @xref{Gtroff Internals},
-for more information on switching compatibility mode on and off in a
-single document.
-
-@pindex trace.tmac
-Using @file{trace.tmac}, you can trace calls to @code{de} and @code{de1}.

-Note that macro identifiers are shared with identifiers for strings and
-diversions.

-@cindex appending to a macro (@code{am})
-@cindex macro, appending (@code{am})
-Works similarly to @code{de} except it appends onto the macro named
-@var{name}.  So, to make the previously defined @samp{P} macro actually
-do indented instead of block paragraphs, add the necessary code to the
-existing macro like this:
-
-@Example
-.am P
-.ti +5n
-..
-@endExample
-
-The @code{am1} request turns off compatibility mode
-while executing the appended macro piece.  To be more precise, a
-@dfn{compatibility save} input token is inserted at the beginning of
-the appended code, and a @dfn{compatibility restore} input token at
-the end.
-
-The @code{ami} request appends indirectly,
-meaning that @code{gtroff} expands strings whose names
-are @var{name} or @var{end} before performing the append.
-
-The @code{ami1} request is similar to @code{ami} but compatibility mode
-is switched off during execution of the defined macro.

-if the name of the macro, diversion or string diversion is currently
-undefined or if it is defined to be a request; normally they modify the

-
-@Defreq {return, [@Var{anything}]}
-Exit a macro, immediately returning to the caller.

-When @code{gtroff} reads in the text for a macro, string, or diversion,

-What this means is that you can specify when these escapes are to be

-
-The arguments to a macro or string can be examined using a variety of
-escapes.
-
-@Defreg {.$}
-@cindex number of arguments register (@code{.$})
-The number of arguments passed to a macro or string.  This is a read-only
-number register.
-
-Note that the @code{shift} request can change its value.
-@endDefreg
-
-Any individual argument can be retrieved with one of the following
-escapes:
-
-@DefescList {\\$, , n, }
-@DefescItem {\\$, @Lparen{}, nn, }
-@DefescListEnd {\\$, @Lbrack{}, nnn, @Rbrack{}}
-@cindex copy-in mode, and macro arguments
-@cindex macro, arguments (@code{\$})
-@cindex arguments, macro (@code{\$})
-Retrieve the @var{n}@dmn{th}, @var{nn}@dmn{th} or @var{nnn}@dmn{th}
-argument.  As usual, the first form only accepts a single number
-(larger than zero), the second a two-digit number (larger or equal
-to@tie{}10), and the third any positive integer value (larger
-than zero).  Macros and strings can have an unlimited number of arguments.
-Note that due to copy-in mode, use two backslashes on these in actual use
-to prevent interpolation until the macro is actually invoked.
-@endDefesc
-
-@Defreq {shift, [@Var{n}]}
-Shift the arguments 1@tie{}position, or as
-many positions as specified by its argument.  After executing this
-request, argument@tie{}@var{i} becomes argument @math{@var{i}-@var{n}};
-arguments 1 to@tie{}@var{n} are no longer available.  Shifting by
-negative amounts is currently undefined.
-
-The register @code{.$} is adjusted accordingly.
-@endDefreq
-
-@DefescList {\\$*, , , }
-@DefescListEnd {\\$@@, , , }
-In some cases it is convenient to use all of the arguments at once (for
-example, to pass the arguments along to another macro).  The @code{\$*}
-escape concatenates all the arguments separated by spaces.  A
-similar escape is @code{\$@@}, which concatenates all the
-arguments with each surrounded by double quotes, and separated by
-spaces.  If not in compatibility mode, the input level of double quotes
-is preserved (see @ref{Request and Macro Arguments}).
-@endDefesc
-
-@Defesc {\\$0, , , }
-@cindex macro name register (@code{\$0})
-@cindex @code{als} request, and @code{\$0}
-The name used to invoke the current macro.
-The @code{als} request can make a macro have more than one name.

-@code{gtroff} provides a number of ways to draw lines and other figures
-on the page.  Used in combination with the page motion commands (see
-@ref{Page Motions}, for more info), a wide variety of figures can be
-drawn.  However, for complex drawings these operations can be quite
-cumbersome, and it may be wise to use graphic preprocessors like
-@code{gpic} or @code{ggrn}.  @xref{gpic}, and @ref{ggrn}, for more
-information.
-
-All drawing is done via escapes.

-@cindex drawing horizontal lines (@code{\l})
-@cindex horizontal line, drawing (@code{\l})
-@cindex line, horizontal, drawing (@code{\l})
-Draw a line horizontally.  @var{l} is the length of the line to be
-drawn.  If it is positive, start the line at the current location and
-draw to the right; its end point is the new current location.  Negative
-values are handled differently: The line starts at the current location
-and draws to the left, but the current location doesn't move.
-
-@var{l} can also be specified absolutely (i.e.@: with a leading
-@samp{|}) which draws back to the beginning of the input line.
-Default scaling indicator is @samp{m}.

-@cindex underscore glyph (@code{\[ru]})
-@cindex glyph, underscore (@code{\[ru]})
-@cindex line drawing glyph
-@cindex glyph, for line drawing
-The optional second parameter@tie{}@var{g} is a glyph to draw the line

-the underscore glyph, @code{\[ru]}.
-
-@cindex zero width space character (@code{\&})
-@cindex character, zero width space (@code{\&})
-@cindex space character, zero width (@code{\&})
-To separate the two arguments (to prevent @code{gtroff} from
-interpreting a drawing glyph as a scaling indicator if the glyph is
-represented by a single character) use @code{\&}.

-Here a small useful example:
-
-@Example
-.de box

-
-@noindent
-Note that this works by outputting a box rule (a vertical line), then
-the text given as an argument and then another box rule.  Finally, the
-line drawing escapes both draw from the current location to the
-beginning of the @emph{input} line -- this works because the line
-length is negative, not moving the current point.

-@cindex traps, page location
-
-@dfn{Page location traps} perform an action when @code{gtroff}
-reaches or passes a certain vertical location on the page.  Page
-location traps have a variety of purposes, including:
-
-@itemize

-@cindex vertical position traps, enabling (@code{vpt})
-@cindex vertical position trap enable register (@code{.vpt})
-Enable vertical position traps if @var{flag} is non-zero, or disables
-them otherwise.  Vertical position traps are traps set by the @code{wh}
-or @code{dt} requests.  Traps set by the @code{it} request are not
-vertical position traps.  The parameter that controls whether vertical
-position traps are enabled is global.  Initially vertical position traps
-are enabled.  The current setting of this is available in the
-@code{.vpt} read-only number register.
-
-Note that a page can't be ejected if @code{vpt} is set to zero.
-@endDefreq
-
-@Defreq {wh, dist [@Var{macro}]}
-Set a page location trap.  Non-negative values for @var{dist} set
-the trap relative to the top of the page; negative values set
-the trap relative to the bottom of the page.  Default scaling
-indicator is @samp{v}.
-
-@var{macro} is the name of the macro to execute when the

-@endExample
-
-A trap at or below the bottom of the page is ignored; it can be made
-active by either moving it up or increasing the page length so that the
-trap is on the page.
-
-It is possible to have more than one trap at the same location; to do so,
-the traps must be defined at different locations, then moved together with
-the @code{ch} request; otherwise the second trap would replace the first
-one.  Earlier defined traps hide later defined traps if moved to the same

-@cindex diversions, and traps
-@cindex traps, and diversions
-An important fact to consider while designing macros is that diversions and
-traps do not interact normally.  For example, if a trap invokes a header
-macro (while outputting a diversion) which tries to change the font on the
-current page, the effect will not be visible before the diversion has
-completely been printed (except for input protected with @code{\!} or
-@code{\?}) since the data in the diversion is already formatted.  In most
-cases, this is not the expected behaviour.

-It happens frequently that some text should be printed in a certain
-format regardless of what may be in effect at the time, for example, in
-a trap invoked macro to print headers and footers.  To solve this
-@code{gtroff} processes text in @dfn{environments}.  An
-environment contains most of the parameters that control text
-processing.  It is possible to switch amongst these environments; by
-default @code{gtroff} processes text in environment@tie{}0.  The
-following is the information kept in an environment.
-
-@itemize @bullet
-@item
-font parameters (size, family, style, glyph height and slant, space
-and sentence space size)
-
-@item
-page parameters (line length, title length, vertical spacing,
-line spacing, indentation, line numbering, centering, right-justifying,
-underlining, hyphenation data)
-

-These environments may be given arbitrary names (see @ref{Identifiers},

-@cindex environment, switching (@code{ev})
-@cindex environment number/name register (@code{.ev})
-Switch to another environment.  The argument @var{env} is the name of
-the environment to switch to.  With no argument, @code{gtroff} switches
-back to the previous environment.  There is no limit on the number of
-named environments; they are created the first time that they are
-referenced.  The @code{.ev} read-only register contains the name or
-number of the current environment.  This is a string-valued register.
-
-Note that a call to @code{ev} (with argument) pushes the previously
-active environment onto a stack.  If, say, environments @samp{foo},
-@samp{bar}, and @samp{zap} are called (in that order), the first
-@code{ev} request without parameter switches back to environment
-@samp{bar} (which is popped off the stack), and a second call
-switches back to environment @samp{foo}.

-
-Internally, @code{color} sets a global flag; it does not produce a token.
-Similar to the @code{cp} request, you should use it at the beginning of

-
-Colors can be also turned off with the @option{-c} command line option.
-@endDefreq
-
-@Defreq {defcolor, ident scheme color_components}
-Define color with name @var{ident}.  @var{scheme} can be one of  the

-components), @code{cmyk} (four components), and @code{gray} or
-@code{grey} (one component).
-
-@cindex default color
-@cindex color, default
-Color components can be given either as a hexadecimal string or as
-positive decimal integers in the range 0--65535.  A hexadecimal string
-contains all color components concatenated.  It must start with either
-@code{#} or @code{##}; the former specifies hex values in the range
-0--255 (which are internally multiplied by@tie{}257), the latter in the
-range 0--65535.  Examples: @code{#FFC0CB} (pink), @code{##ffff0000ffff}
-(magenta).  The default color name @c{default} can't be redefined; its
-value is device-specific (usually black).  It is possible that the
-default color for @code{\m} and @code{\M} is not identical.

-@cindex unit, @code{f}, and colors
-A new scaling indicator@tie{}@code{f} has been introduced which multiplies

-as fractions in the range 0 to@tie{}1 (1f equals 65536u).  Example:
-
-@Example
-.defcolor darkgreen rgb 0.1f 0.5f 0.2f
-@endExample
-
-Note that @code{f} is the default scaling indicator for the

-
-Note that @code{\m} doesn't produce an input token in @code{gtroff}.
-As a consequence, it can be used in requests like @code{mc} (which

-@cindex input and output requests
-@cindex requests for input and output
-@cindex output and input requests
-
-@code{gtroff} has several requests for including files:
-
-@Defreq {so, file}
-@cindex including a file (@code{so})
-@cindex file, inclusion (@code{so})
-Read in the specified @var{file} and
-includes it in place of the @code{so} request.  This is quite useful for
-large documents, e.g.@: keeping each chapter in a separate file.
-@xref{gsoelim}, for more information.
-
-Since @code{gtroff} replaces the @code{so} request with the contents
-of @code{file}, it makes a difference whether the data is terminated with
-a newline or not: Assuming that file @file{xxx} contains the word
-@samp{foo} without a final newline, this
-
-@Example
-This is
-.so xxx
-bar
-@endExample
-
-@noindent
-yields @samp{This is foobar}.
-
-The search path for @var{file} can be controlled with the @option{-I} command
-line option.
-@endDefreq
-
-@Defreq {pso, command}
-Read the standard output from the specified @var{command}
-and includes it in place of the @code{pso} request.
-
-@cindex safer mode
-@cindex mode, safer
-@cindex unsafe mode
-@cindex mode, unsafe
-This request causes an error if used in safer mode (which is the default).
-Use @code{groff}'s or @code{troff}'s @option{-U} option to activate unsafe
-mode.
-
-The comment regarding a final newline for the @code{so} request is valid
-for @code{pso} also.
-@endDefreq
-
-@Defreq {mso, file}
-Identical to the @code{so} request except that @code{gtroff} searches for
-the specified @var{file} in the same directories as macro files for the
-the @option{-m} command line option.  If the file name to be included
-has the form @file{@var{name}.tmac} and it isn't found, @code{mso} tries
-to include @file{tmac.@var{name}} and vice versa.
-@endDefreq
-
-@DefreqList {trf, file}
-@DefreqListEnd {cf, file}
-@cindex transparent output (@code{cf}, @code{trf})
-@cindex output, transparent (@code{cf}, @code{trf})
-Transparently output the contents of @var{file}.  Each line is output
-as if it were preceded by @code{\!}; however, the lines are not subject
-to copy mode interpretation.  If the file does not end with a newline,
-then a newline is added (@code{trf} only).  For example, to define a
-macro@tie{}@code{x} containing the contents of file@tie{}@file{f}, use
-
-@Example
-.di x
-.trf f
-.di
-@endExample
-
-Both @code{trf} and @code{cf}, when used in a diversion,
-embeds an object in the diversion which, when reread, causes the
-contents of @var{file} to be transparently copied through to the
-output.  In @acronym{UNIX} @code{troff}, the contents of @var{file}
-is immediately copied through to the output regardless of whether there
-is a current diversion; this behaviour is so anomalous that it must be
-considered a bug.
-
-@cindex @code{trf} request, and invalid characters
-@cindex characters, invalid for @code{trf} request
-@cindex invalid characters for @code{trf} request
-While @code{cf} copies the contents of @var{file} completely unprocessed,
-@code{trf} disallows characters such as NUL that are not valid
-@code{gtroff} input characters (@pxref{Identifiers}).
-
-Both requests cause a line break.
-@endDefreq
-
-@Defreq {nx, [@Var{file}]}
-@cindex processing next file (@code{nx})
-@cindex file, processing next (@code{nx})
-@cindex next file, processing (@code{nx})
-Force @code{gtroff} to continue processing of
-the file specified as an argument.  If no argument is given, immediately
-jump to the end of file.
-@endDefreq
-
-@Defreq {rd, [@Var{prompt} [@Var{arg1} @Var{arg2} @dots{}]]}
-@cindex reading from standard input (@code{rd})
-@cindex standard input, reading from (@code{rd})
-@cindex input, standard, reading from (@code{rd})
-Read from standard input, and include what is read as though it
-were part of the input file.  Text is read until a blank line
-is encountered.
-
-If standard input is a TTY input device (keyboard), write @var{prompt}
-to standard error, followed by a colon (or send BEL for a beep if no
-argument is given).
-
-Arguments after @var{prompt} are available for the input.  For example,
-the line
-
-@Example
-.rd data foo bar
-@endExample
-
-with the input @w{@samp{This is \$2.}} prints
-
-@Example
-This is bar.
-@endExample
-@endDefreq
-
-@cindex form letters
-@cindex letters, form
-Using the @code{nx} and @code{rd} requests,
-it is easy to set up form letters.  The form
-letter template is constructed like this, putting the following lines
-into a file called @file{repeat.let}:
-
-@Example
-.ce
-\*(td
-.sp 2
-.nf
-.rd
-.sp
-.rd
-.fi
-Body of letter.
-.bp
-.nx repeat.let
-@endExample
-
-@cindex @code{ex} request, used with @code{nx} and @code{rd}
-@noindent
-When this is run, a file containing the following lines should be
-redirected in.  Note that requests included in this file are executed
-as though they were part of the form letter.  The last block of input
-is the @code{ex} request which tells @code{groff} to stop processing.  If
-this was not there, @code{groff} would not know when to stop.

-
-@cindex safer mode
-@cindex mode, safer
-@cindex unsafe mode
-@cindex mode, unsafe
-@code{pi} causes an error if used in safer mode (which is the default).
-Use @code{groff}'s or @code{troff}'s @option{-U} option to activate unsafe
-mode.
-
-Multiple calls to @code{pi} are allowed, acting as a chain.  For example,
-
-@Example
-.pi foo
-.pi bar
-...
-@endExample
-
-is the same as @w{@samp{.pi foo | bar}}.
-
-@cindex @code{groff}, and @code{pi} request
-@cindex @code{pi} request, and @code{groff}
-Note that the intermediate output format of @code{gtroff} is piped to
-the specified commands.  Consequently, calling @code{groff} without the
-@option{-Z} option normally causes a fatal error.
-@endDefreq
-
-@DefreqList {sy, cmds}
-@DefregListEnd {systat}
-Execute the shell command(s) specified by @var{cmds}.  The output is not
-saved anyplace, so it is up to the user to do so.
-
-@cindex safer mode
-@cindex mode, safer
-@cindex unsafe mode

-This request causes an error if used in safer mode (which is the default).
-Use @code{groff}'s or @code{troff}'s @option{-U} option to activate unsafe

-
-For example, the following code fragment introduces the current time into a

-
-@cindex time, current

-.so /tmp/x\n[$$]
-.sy rm /tmp/x\n[$$]
-\nH:\nM:\nS
-@endExample
-
-@noindent
-Note that this works by having the @code{perl} script (run by @code{sy})
-print out the @code{nr} requests which set the number registers
-@code{H}, @code{M}, and @code{S}, and then reads those commands in with
-the @code{so} request.
-
-For most practical purposes, the number registers @code{seconds},
-@code{minutes}, and @code{hours} which are initialized at start-up of
-@code{gtroff} should be sufficient.  Use the @code{af} request to get a
-formatted output:
-
-@Example
-.af hours 00
-.af minutes 00
-.af seconds 00
-\n[hours]:\n[minutes]:\n[seconds]
-@endExample
-
-@cindex @code{system()} return value register (@code{systat})

-
-@var{xx} is read in copy mode, i.e., already formatted elements are

-(one-character name@tie{}@var{n}, two-character name @var{nm}).
-However, the contents of the string or macro @var{name} are not
-interpreted; also it is permitted for @var{name} to have been defined
-as a macro and thus contain newlines (it is not permitted for the
-argument to @code{\X} to contain newlines).  The inclusion of
-newlines requires an extension to the @acronym{UNIX} @code{troff}
-output format, and confuses drivers that do not know about this
-extension (@pxref{Device Control Commands}).

-
-This section documents parts of @code{gtroff} which cannot (yet) be
-categorized elsewhere in this manual.
-
-@Defreq {nm, [@Var{start} [@Var{inc} [@Var{space} [@Var{indent}]]]]}
-@cindex printing line numbers (@code{nm})
-@cindex line numbers, printing (@code{nm})
-@cindex numbers, line, printing (@code{nm})
-Print line numbers.
-@var{start} is the line number of the @emph{next}
-output line.  @var{inc} indicates which line numbers are printed.
-For example, the value@tie{}5 means to emit only line numbers which
-are multiples of@tie{}5; this defaults to@tie{}1.  @var{space} is the
-space to be left between the number and the text; this defaults to
-one digit space.  The fourth argument is the indentation of the line
-numbers, defaulting to zero.  Both @var{space} and @var{indent} are
-given as multiples of digit spaces; they can be negative also.
-Without any arguments, line numbers are turned off.
-
-@code{gtroff} reserves three digit spaces for the line number (which is
-printed right-justified) plus the amount given by @var{indent}; the
-output lines are concatenated to the line numbers, separated by
-@var{space}, and @emph{without} reducing the line length.  Depending
-on the value of the horizontal page offset (as set with the
-@code{po} request), line numbers which are longer than the reserved
-space stick out to the left, or the whole line is moved to the right.
-
-Parameters corresponding to missing arguments are not changed; any
-non-digit argument (to be more precise, any argument starting with a
-character valid as a delimiter for identifiers) is also treated as
-missing.
-
-If line numbering has been disabled with a call to @code{nm} without
-an argument, it can be reactivated with @samp{.nm +0}, using the
-previously active line numbering parameters.
-
-The parameters of @code{nm} are associated with the current environment
-(@pxref{Environments}).  The current output line number is available
-in the number register @code{ln}.
-

-And here the result:
-
-@Example
- This  test shows how

-@endExample
-@endDefreq

-@endDefreq
-
-@Defreq {mc, glyph [@Var{dist}]}
-@cindex margin glyph (@code{mc})
-@cindex glyph, for margins (@code{mc})
-Print a @dfn{margin character} to the right of the
-text.@footnote{@dfn{Margin character} is a misnomer since it is an
-output glyph.}  The first argument is the glyph to be
-printed.  The second argument is the distance away from the right
-margin.  If missing, the previously set value is used; default is
-10@dmn{pt}).  For text lines that are too long (that is, longer than
-the text length plus @var{dist}), the margin character is directly
-appended to the lines.
-
-With no arguments the margin character is turned off.
-If this occurs before a break, no margin character is printed.
-
-For compatibility with @acronym{AT&T} @code{troff}, a call to @code{mc}
-to set the margin character can't be undone immediately; at least one
-line gets a margin character.  Thus
-
-@Example
-.ll 1i
-.mc \[br]
-.mc
-xxx
-.br
-xxx
-@endExample
-
-@noindent
-produces
-
-@Example

-xxx
-@endExample
-
-@cindex @code{tl} request, and @code{mc}
-For empty lines and lines produced by the @code{tl} request no margin
-character is emitted.
-
-The margin character is associated with the current environment
-(@pxref{Environments}).
-
-@pindex nrchbar
-@pindex changebar
-This is quite useful for indicating text that has changed, and, in fact,
-there are programs available for doing this (they are called

-@cindex input token
-@cindex token, input
-@cindex output node
-@cindex node, output
-@code{gtroff} processes input in three steps.  One or more input
-characters are converted to an @dfn{input token}.@footnote{Except the
-escapes @code{\f}, @code{\F}, @code{\H}, @code{\m}, @code{\M}, @code{\R},
-@code{\s}, and @code{\S} which are processed immediately if not in
-copy-in mode.}  Then, one or more input tokens are converted to an
-@dfn{output node}.  Finally, output nodes are converted to the
-intermediate output language understood by all output devices.
-
-Actually, before step one happens, @code{gtroff} converts certain
-escape sequences into reserved input characters (not accessible by
-the user); such reserved characters are used for other internal
-processing also -- this is the very reason why not all characters
-are valid input.  @xref{Identifiers}, for more on this topic.
-
-For example, the input string @samp{fi\[:u]} is converted into a
-character token @samp{f}, a character token @samp{i}, and a special
-token @samp{:u} (representing u@tie{}umlaut).  Later on, the character
-tokens @samp{f} and @samp{i} are merged to a single output node
-representing the ligature glyph @samp{fi} (provided the current font
-has a glyph for this ligature); the same happens with @samp{:u}.  All
-output glyph nodes are `processed' which means that they are invariably
-associated with a given font, font size, advance width, etc.  During
-the formatting process, @code{gtroff} itself adds various nodes to
-control the data flow.
-
-Macros, diversions, and strings collect elements in two chained lists:
-a list of input tokens which have been passed unprocessed, and a list
-of output nodes.  Consider the following the diversion.
-
-@Example
-.di xxx
-a
-\!b
-c
-.br
-.di
-@endExample
-
-@noindent
-It contains these elements.
-
-@multitable {@i{vertical size node}} {token list} {element number}
-@item node list               @tab token list @tab element number
-
-@item @i{line start node}     @tab ---        @tab 1
-@item @i{glyph node @code{a}} @tab ---        @tab 2
-@item @i{word space node}     @tab ---        @tab 3
-@item ---                     @tab @code{b}   @tab 4
-@item ---                     @tab @code{\n}  @tab 5
-@item @i{glyph node @code{c}} @tab ---        @tab 6

-@item @i{vertical size node}  @tab ---        @tab 8
-@item ---                     @tab @code{\n}  @tab 9
-@end multitable
-
-@cindex @code{\v}, internal representation
-@noindent
-Elements 1, 7, and@tie{}8 are inserted by @code{gtroff}; the latter two
-(which are always present) specify the vertical extent of the last
-line, possibly modified by @code{\x}.  The @code{br} request finishes
-the current partial line, inserting a newline input token which is
-subsequently converted to a space when the diversion is reread.  Note
-that the word space node has a fixed width which isn't stretchable
-anymore.  To convert horizontal space nodes back to input tokens, use
-the @code{unformat} request.
-
-Macros only contain elements in the token list (and the node list is
-empty); diversions and strings can contain elements in both lists.
-
-Note that the @code{chop} request simply reduces the number of elements in a
-macro, string, or diversion by one.  Exceptions are @dfn{compatibility save}
-and @dfn{compatibility ignore} input tokens which are ignored.  The
-@code{substring} request also ignores those input tokens.
-
-Some requests like @code{tr} or @code{cflags} work on glyph
-identifiers only; this means that the associated glyph can be changed
-without destroying this association.  This can be very helpful for
-substituting glyphs.  In the following example, we assume that
-glyph @samp{foo} isn't available by default, so we provide a
-substitution using the @code{fchar} request and map it to input
-character @samp{x}.
-
-@Example
-.fchar \[foo] foo
-.tr x \[foo]
-@endExample
-
-@noindent
-Now let us assume that we install an additional special font
-@samp{bar} which has glyph @samp{foo}.
-
-@Example
-.special bar
-.rchar \[foo]
-@endExample
-
-@noindent
-Since glyphs defined with @code{fchar} are searched before glyphs
-in special fonts, we must call @code{rchar} to remove the definition
-of the fallback glyph.  Anyway, the translation is still active;
-@samp{x} now maps to the real glyph @samp{foo}.
-
-@cindex compatibility mode, and parameters
-@cindex mode, compatibility, and parameters
-@cindex arguments, and compatibility mode
-@cindex parameters, and compatibility mode
-@cindex macro arguments, and compatibility mode
-@cindex request arguments, and compatibility mode
-Macro and request arguments preserve the compatibility mode:
-
-@Example
-.cp 1     \" switch to compatibility mode
-.de xx
-\\$1
-..
-.cp 0     \" switch compatibility mode off
-.xx caf\['e]
-    @result{} café
-@endExample
-
-@noindent
-Since compatibility mode is on while @code{de} is called, the macro
-@code{xx} activates compatibility mode while executing.  Argument
-@code{$1} can still be handled properly because it inherits the
-compatibility mode status which was active at the point where @code{xx}
-is called.
-
-After expansion of the parameters, the compatibility save and restore
-tokens are removed.

-@cindex documents, multi-file
-@cindex setting input line number (@code{lf})
-@cindex input line number, setting (@code{lf})
-@cindex number, input line, setting (@code{lf})
-Change the line number and optionally the file name @code{gtroff} shall
-use for error and warning messages.  @var{line} is the input line number
-of the @emph{next} line.
-
-Without argument, the request is ignored.
-
-This is a debugging aid for documents which are split into many files,
-then put together with @code{soelim} and other preprocessors.  Usually,
-it isn't invoked manually.
-
-Note that other @code{troff} implementations (including the original
-@acronym{AT&T} version) handle @code{lf} differently.  For them,
-@var{line} changes the line number of the @emph{current} line.
-@endDefreq
-
-@DefreqList {tm, string}
-@DefreqItem {tm1, string}
-@DefreqListEnd {tmc, string}
-@cindex printing to stderr (@code{tm}, @code{tm1}, @code{tmc})
-@cindex stderr, printing to (@code{tm}, @code{tm1}, @code{tmc})
-Send @var{string} to the standard error output;
-this is very useful for printing debugging messages among other things.
-
-@var{string} is read in copy mode.
-
-The @code{tm} request ignores leading spaces of @var{string}; @code{tm1}
-handles its argument similar to the @code{ds} request: a leading double
-quote in @var{string} is stripped to allow initial blanks.
-
-The @code{tmc} request is similar to @code{tm1} but does
-not append a newline (as is done in @code{tm} and @code{tm1}).
-@endDefreq
-
-@Defreq {ab, [@Var{string}]}
-@cindex aborting (@code{ab})
-Similar to the @code{tm} request, except that
-it causes @code{gtroff} to stop processing.  With no argument it
-prints @samp{User Abort.} to standard error.
-@endDefreq
-
-@Defreq {ex, }
-@cindex @code{ex} request, use in debugging
-@cindex exiting (@code{ex})
-The @code{ex} request also causes @code{gtroff} to stop processing;
-see also @ref{I/O}.
-@endDefreq
-
-When doing something involved it is useful to leave the debugging
-statements in the code and have them turned on by a command line flag.
-
-@Example
-.if \n(DB .tm debugging output
-@endExample
-
-@noindent
-To activate these statements say
-
-@Example
-groff -rDB=1 file
-@endExample
-
-If it is known in advance that there will be many errors and no useful
-output, @code{gtroff} can be forced to suppress formatted output with
-the @option{-z} flag.
-
-@Defreq {pm, }
-@cindex dumping symbol table (@code{pm})
-@cindex symbol table, dumping (@code{pm})
-Print the entire symbol table on @code{stderr}.  Names of all defined
-macros, strings, and diversions are print together with their size in
-bytes.  Since @code{gtroff} sometimes adds nodes by itself, the
-returned size can be larger than expected.
-
-This request differs from @acronym{UNIX} @code{troff}: @code{gtroff}
-reports the sizes of diversions, ignores an additional argument to
-print only the total of the sizes, and the size isn't returned in
-blocks of 128 characters.
-@endDefreq
-
-@Defreq {pnr, }
-@cindex dumping number registers (@code{pnr})
-@cindex number registers, dumping (@code{pnr})

-@endDefreq
-
-@Defreq {ptr, }
-@cindex dumping traps (@code{ptr})
-@cindex traps, dumping (@code{ptr})
-Print the names and positions of all traps
-(not including input line traps and diversion traps) on @code{stderr}.
-Empty slots in the page trap list are printed as well, because they can
-affect the priority of subsequently planted traps.

-@cindex flush output (@code{fl})
-@cindex output, flush (@code{fl})
-@cindex interactive use of @code{gtroff}
-@cindex @code{gtroff}, interactive use
-Instruct @code{gtroff} to flush its output immediately.  The intent
-is for interactive use, but this behaviour is currently not
-implemented in @code{gtroff}.  Contrary to @acronym{UNIX} @code{troff},
-TTY output is sent to a device driver also (@code{grotty}), making it
-non-trivial to communicate interactively.
-
-This request causes a line break.
-@endDefreq
-
-@Defreq {backtrace, }
-@cindex backtrace of input stack (@code{backtrace})
-@cindex input stack, backtrace (@code{backtrace})
-Print a backtrace of the input stack to the standard error stream.
-
-Consider the following in file @file{test}:
-
-@Example
-.de xxx
-.  backtrace
-..
-.de yyy
-.  xxx
-..
-.
-.yyy
-@endExample

-On execution, @code{gtroff} prints the following:
-
-@Example
-test:2: backtrace: macro `xxx'
-test:5: backtrace: macro `yyy'
-test:8: backtrace: file `test'

-Use the @code{slimit} number register
-to set the maximum number of objects on the input stack.
-If @code{slimit} is less than or equal to@tie{}0,

-With no limit, a buggy recursive macro can exhaust virtual memory.
-
-The default value is 1000; this is a compile-time constant.
-@endDefreg
-
-@Defreq {warnscale, si}
-Set the scaling indicator used in warnings to @var{si}.  Valid values for
-@var{si} are @samp{u}, @samp{i}, @samp{c}, @samp{p}, and @samp{P}.  At
-startup, it is set to @samp{i}.
-@endDefreq
-
-@Defreq {spreadwarn, [@Var{limit}]}
-Make @code{gtroff} emit a warning if the additional space inserted for
-each space between words in an output line is larger or equal to
-@var{limit}.  A negative value is changed to zero; no argument toggles the
-warning on and off without changing @var{limit}.  The default scaling
-indicator is @samp{m}.  At startup, @code{spreadwarn} is deactivated, and
-@var{limit} is set to 3@dmn{m}.
-
-For example,
-
-@Example
-.spreadwarn 0.2m
-@endExample
-

-
-GNU @code{troff} has a number of features which cause incompatibilities
-with documents written with old versions of @code{troff}.
-
-@cindex long names
-@cindex names, long
-Long names cause some incompatibilities.  @acronym{UNIX} @code{troff}

-@cindex @code{\*}, incompatibilities with @acronym{AT&T} @code{troff}
-@cindex @code{\n}, incompatibilities with @acronym{AT&T} @code{troff}
-@noindent
-as defining a string @samp{ab} with contents @samp{cd}.  Normally, GNU
-@code{troff} interprets this as a call of a macro named
-@code{dsabcd}.  Also @acronym{UNIX} @code{troff} interprets
-@code{\*[} or @code{\n[} as references to a string or number register
-called @samp{[}.  In GNU @code{troff}, however, this is normally
-interpreted as the start of a long name.  In compatibility mode GNU
-@code{troff} interprets long names in the traditional way
-(which means that they are not recognized as names).
-
-@DefreqList {cp, [@Var{n}]}
-@DefreqItem {do, cmd}
-@DefregListEnd {.C}
-If @var{n} is missing or non-zero, turn on compatibility mode;
-otherwise, turn it off.
-
-The read-only number register @code{.C} is@tie{}1 if compatibility mode is
-on, 0@tie{}otherwise.
-
-Compatibility mode can be also turned on with the @option{-C} command line
-option.
-
-The @code{do} request turns off compatibility mode
-while executing its arguments as a @code{gtroff} command.
-
-@Example
-.do fam T
-@endExample
-
-@noindent
-executes the @code{fam} request when compatibility mode
-is enabled.
-
-@code{gtroff} restores the previous compatibility setting
-before interpreting any files sourced by the @var{cmd}.
-@endDefreq
-
-@cindex input level in delimited arguments
-@cindex delimited arguments, incompatibilities with @acronym{AT&T} @code{troff}
-Two other features are controlled by @option{-C}.  If not in
-compatibility mode, GNU @code{troff} preserves the input level in
-delimited arguments:
-
-@Example
-.ds xx '
-\w'abc\*(xxdef'
-@endExample
-
-@noindent
-In compatibility mode, the string @samp{72def'} is returned; without
-@option{-C} the resulting string is @samp{168} (assuming a TTY output
-device).
-
-@cindex @code{\f}, incompatibilities with @acronym{AT&T} @code{troff}
-@cindex @code{\H}, incompatibilities with @acronym{AT&T} @code{troff}
-@cindex @code{\s}, incompatibilities with @acronym{AT&T} @code{troff}
-@cindex @code{\S}, incompatibilities with @acronym{AT&T} @code{troff}
-Finally, the escapes @code{\f}, @code{\H}, @code{\m}, @code{\M},
-@code{\R}, @code{\s}, and @code{\S} are transparent for recognizing the
-beginning of a line only in compatibility mode (this is a rather obscure
-feature).  For example, the code
-
-@Example
-.de xx
-Hallo!
-..
-\fB.xx\fP
-@endExample
-
-@noindent
-prints @samp{Hallo!} in bold face if in compatibility mode, and
-@samp{.xx} in bold face otherwise.

-@cindex glyphs, output, and input characters, compatibility with @acronym{AT&T} @code{troff}
-In GNU @code{troff} there is a fundamental difference between
-(unformatted) input characters and (formatted) output glyphs.
-Everything that affects how a glyph is output is stored
-with the glyph node; once a glyph node has been constructed it is
-unaffected by any subsequent requests that are executed, including
-@code{bd}, @code{cs}, @code{tkf}, @code{tr}, or @code{fp} requests.
-Normally glyphs are constructed from input characters at the
-moment immediately before the glyph is added to the current output
-line.  Macros, diversions and strings are all, in fact, the same type of
-object; they contain lists of input characters and glyph nodes in
-any combination.  A glyph node does not behave like an input
-character for the purposes of macro processing; it does not inherit any
-of the special properties that the input character from which it was
-constructed might have had.  For example,

-@noindent
-prints @samp{\\} in GNU @code{troff}; each pair of input backslashes
-is turned into one output backslash and the resulting output backslashes
-are not interpreted as escape characters when they are reread.
-@acronym{UNIX} @code{troff} would interpret them as escape characters
-when they were reread and would end up printing one @samp{\}.  The
-correct way to obtain a printable backslash is to use the @code{\e}
-escape sequence: This always prints a single instance of the current
-escape character, regardless of whether or not it is used in a
-diversion; it also works in both GNU @code{troff} and @acronym{UNIX}
-@code{troff}.@footnote{To be completely independent of the current
-escape character, use @code{\(rs} which represents a reverse solidus
-(backslash) glyph.}  To store, for some reason, an escape sequence in a
-diversion that will be interpreted when the diversion is reread, either
-use the traditional @code{\!} transparent output facility, or, if this
-is unsuitable, the new @code{\?} escape sequence.

-
-This section describes the intermediate output format of GNU
-@code{troff}.  This output is produced by a run of @code{gtroff}
-before it is fed into a device postprocessor program.
-
-As @code{groff} is a wrapper program around @code{gtroff} that
-automatically calls a postprocessor, this output does not show up
-normally.  This is why it is called @dfn{intermediate}.
-@code{groff} provides the option @option{-Z} to inhibit postprocessing,
-such that the produced intermediate output is sent to standard output
-just like calling @code{gtroff} manually.
-
-@cindex troff output
-@cindex output, troff
-@cindex intermediate output
-@cindex output, intermediate
-Here, the term @dfn{troff output} describes what is output by
-@code{gtroff}, while @dfn{intermediate output} refers to the language
-that is accepted by the parser that prepares this output for the
-postprocessors.  This parser is smarter on whitespace and implements
-obsolete elements for compatibility, otherwise both formats are the
-same.@footnote{The parser and postprocessor for intermediate output
-can be found in the file@*
-@file{@var{groff-source-dir}/src/libs/libdriver/input.cpp}.}
-
-The main purpose of the intermediate output concept is to facilitate
-the development of postprocessors by providing a common programming
-interface for all devices.  It has a language of its own that is
-completely different from the @code{gtroff} language.  While the
-@code{gtroff} language is a high-level programming language for text
-processing, the intermediate output language is a kind of low-level
-assembler language by specifying all positions on the page for writing
-and drawing.
-
-The intermediate output produced by @code{gtroff} is fairly readable,
-while output from @acronym{AT&T} @code{troff} is rather hard to
-understand because of strange habits that are still supported, but not
-used any longer by @code{gtroff}.

-@subsection Language Concepts
-
-During the run of @code{gtroff}, the input data is cracked down to the
-information on what has to be printed at what position on the intended
-device.  So the language of the intermediate output format can be quite
-small.  Its only elements are commands with and without arguments.
-In this section, the term @dfn{command} always refers to the intermediate
-output language, and never to the @code{gtroff} language used for document
-formatting.  There are commands for positioning and text writing, for drawing, and
-for device controlling.

-
-@node Separation, Argument Units, Language Concepts, Language Concepts
-@subsubsection Separation
-
-@acronym{AT&T} @code{troff} output has strange requirements on whitespace.
-The @code{gtroff} output parser, however, is smart about whitespace by
-making it maximally optional.  The whitespace characters, i.e., the
-tab, space, and newline characters, always have a syntactical meaning.
-They are never printable because spacing within the output is always
-done by positioning commands.
-
-Any sequence of space or tab characters is treated as a single
-@dfn{syntactical space}.  It separates commands and arguments, but is
-only required when there would occur a clashing between the command code
-and the arguments without the space.  Most often, this happens when
-variable-length command names, arguments, argument lists, or command
-clusters meet.  Commands and arguments with a known, fixed length need
-not be separated by syntactical space.
-
-A line break is a syntactical element, too.  Every command argument can be
-followed by whitespace, a comment, or a newline character.  Thus a
-@dfn{syntactical line break} is defined to consist of optional
-syntactical space that is optionally followed by a comment, and a
-newline character.
-
-The normal commands, those for positioning and text, consist of a
-single letter taking a fixed number of arguments.  For historical reasons,
-the parser allows to stack such commands on the same line, but
-fortunately, in @code{gtroff}'s intermediate output, every command with
-at least one argument is followed by a line break, thus providing
-excellent readability.
-
-The other commands -- those for drawing and device controlling --
-have a more complicated structure; some recognize long command names,
-and some take a variable number of arguments.  So all @samp{D} and
-@samp{x} commands were designed to request a syntactical line break
-after their last argument.  Only one command, @w{@samp{x X}},
-has an argument that can stretch over several lines; all other
-commands must have all of their arguments on the same line as the
-command, i.e., the arguments may not be splitted by a line break.
-
-Empty lines (these are lines containing only space and/or a comment), can
-occur everywhere.  They are just ignored.
-
-@node Argument Units, Document Parts, Separation, Language Concepts
-@subsubsection Argument Units
-
-Some commands take integer arguments that are assumed to represent
-values in a measurement unit, but the letter for the corresponding
-scale indicator is not written with the output command arguments.
-Most commands assume the scale indicator @samp{u}, the basic unit of
-the device, some use @samp{z}, the scaled point unit of the device,
-while others, such as the color commands, expect plain integers.
-
-Note that single characters can have the eighth bit set, as can the
-names of fonts and special characters.  The names of characters and
-fonts can be of arbitrary length.  A character that is to be printed
-will always be in the current font.
-
-A string argument is always terminated by the next whitespace
-character (space, tab, or newline); an embedded @samp{#} character is
-regarded as part of the argument, not as the beginning of a comment
-command.  An integer argument is already terminated by the next
-non-digit character, which then is regarded as the first character of
-the next argument or command.
-
-@node Document Parts,  , Argument Units, Language Concepts
-@subsubsection Document Parts
-
-A correct intermediate output document consists of two parts, the
-@dfn{prologue} and the @dfn{body}.
-
-The task of the prologue is to set the general device parameters
-using three exactly specified commands.  @code{gtroff}'s prologue
-is guaranteed to consist of the following three lines (in that order):
-
-@Example
-x T @var{device}
-x res @var{n} @var{h} @var{v}
-x init
-@endExample
-
-@noindent
-with the arguments set as outlined in @ref{Device Control Commands}.
-Note that the parser for the intermediate output format is able to
-swallow additional whitespace and comments as well even in the
-prologue.
-
-The body is the main section for processing the document data.
-Syntactically, it is a sequence of any commands different from the
-ones used in the prologue.  Processing is terminated as soon as the
-first @w{@samp{x stop}} command is encountered; the last line of any
-@code{gtroff} intermediate output always contains such a command.
-
-Semantically, the body is page oriented.  A new page is started by a
-@samp{p} command.  Positioning, writing, and drawing commands are
-always done within the current page, so they cannot occur before the
-first @samp{p} command.  Absolute positioning (by the @samp{H} and
-@samp{V} commands) is done relative to the current page; all other
-positioning is done relative to the current location within this page.

-@subsubsection Simple Commands
-
-The commands in this subsection have a command code consisting of a
-single character, taking a fixed number of arguments.  Most of them
-are commands for positioning and text writing.  These commands are
-smart about whitespace.  Optionally, syntactical space can be inserted
-before, after, and between the command letter and its arguments.
-All of these commands are stackable, i.e., they can be preceded by
-other simple commands or followed by arbitrary other commands on the
-same line.  A separating syntactical space is only necessary when two
-integer arguments would clash or if the preceding argument ends with a
-string argument.
-
-@table @code

-.BR { \~command)
-and restore the previous environment from the environment
-stack as the actual device configuration data.
-.
-\}              \" endif @USE_ENV_STACK
-@end ignore
-
-@item C @var{xxx}@angles{whitespace}
-Print a special character named @var{xxx}.  The trailing
-syntactical space or line break is necessary to allow glyph names
-of arbitrary length.  The glyph is printed at the current print
-position; the glyph's size is read from the font file.  The print
-position is not changed.
-
-@item c @var{g}
-Print glyph@tie{}@var{g} at the current print position;@footnote{@samp{c}
-is actually a misnomer since it outputs a glyph.} the glyph's size is
-read from the font file.  The print position is not changed.
-
-@item f @var{n}
-Set font to font number@tie{}@var{n} (a non-negative integer).
-
-@item H @var{n}
-Move right to the absolute vertical position@tie{}@var{n} (a
-non-negative integer in basic units @samp{u} relative to left edge
-of current page.
-
-@item h @var{n}
-Move @var{n} (a non-negative integer) basic units @samp{u} horizontally
-to the right.  The original @acronym{UNIX} troff manual allows negative
-values for @var{n} also, but @code{gtroff} doesn't use this.
-
-@item m @var{color-scheme} @r{[}@var{component} @dots{}@r{]}
-Set the color for text (glyphs), line drawing, and the outline of
-graphic objects using different color schemes; the analoguous command
-for the filling color of graphic objects is @samp{DF}.  The color
-components are specified as integer arguments between 0 and 65536.
-The number of color components and their meaning vary for the
-different color schemes.  These commands are generated by
-@code{gtroff}'s escape sequence @code{\m}.  No position changing.
-These commands are a @code{gtroff} extension.
-
-@table @code
-@item mc @var{cyan} @var{magenta} @var{yellow}
-Set color using the CMY color scheme, having the 3@tie{}color components
-@var{cyan}, @var{magenta}, and @var{yellow}.
-
-@item md
-Set color to the default color value (black in most cases).
-No component arguments.
-
-@item mg @var{gray}
-Set color to the shade of gray given by the argument, an integer
-between 0 (black) and 65536 (white).
-
-@item mk @var{cyan} @var{magenta} @var{yellow} @var{black}
-Set color using the CMYK color scheme, having the 4@tie{}color components
-@var{cyan}, @var{magenta}, @var{yellow}, and @var{black}.
-
-@item mr @var{red} @var{green} @var{blue}
-Set color using the RGB color scheme, having the 3@tie{}color components
-@var{red}, @var{green}, and @var{blue}.
-@end table
-
-@item N @var{n}
-Print glyph with index@tie{}@var{n} (a non-negative integer) of the
-current font.  This command is a @code{gtroff} extension.
-
-@item n @var{b} @var{a}
-Inform the device about a line break, but no positioning is done by
-this command.  In @acronym{AT&T} @code{troff}, the integer arguments
-@var{b} and@tie{}@var{a} informed about the space before and after the
-current line to make the intermediate output more human readable
-without performing any action.  In @code{groff}, they are just ignored, but
-they must be provided for compatibility reasons.
-
-@item p @var{n}
-Begin a new page in the outprint.  The page number is set
-to@tie{}@var{n}.  This page is completely independent of pages formerly
-processed even if those have the same page number.  The vertical
-position on the outprint is automatically set to@tie{}0.  All
-positioning, writing, and drawing is always done relative to a page,
-so a @samp{p} command must be issued before any of these commands.
-
-@item s @var{n}
-Set point size to @var{n}@tie{}scaled points (this is unit @samp{z}).
-@acronym{AT&T} @code{troff} used the unit points (@samp{p}) instead.
-@xref{Output Language Compatibility}.
-
-@item t @var{xxx}@angles{whitespace}
-@itemx t @var{xxx} @var{dummy-arg}@angles{whitespace}
-Print a word, i.e., a sequence of characters @var{xxx} representing
-output glyphs which names are single characters, terminated by
-a space character or a line break; an optional second integer argument
-is ignored (this allows the formatter to generate an even number of
-arguments).  The first glyph should be printed at the current
-position, the current horizontal position should then be increased by
-the width of the first glyph, and so on for each glyph.
-The widths of the glyphs are read from the font file, scaled for the
-current point size, and rounded to a multiple of the horizontal
-resolution.  Special characters cannot be printed using this command
-(use the @samp{C} command for special characters).  This command is a
-@code{gtroff} extension; it is only used for devices whose @file{DESC}
-file contains the @code{tcommand} keyword (@pxref{DESC File Format}).
-
-@item u @var{n} @var{xxx}@angles{whitespace}
-Print word with track kerning.  This is the same as the @samp{t}
-command except that after printing each glyph, the current
-horizontal position is increased by the sum of the width of that
-glyph and@tie{}@var{n} (an integer in basic units @samp{u}).
-This command is a @code{gtroff} extension; it is only used for devices
-whose @file{DESC} file contains the @code{tcommand} keyword
-(@pxref{DESC File Format}).
-
-@item V @var{n}
-Move down to the absolute vertical position@tie{}@var{n} (a
-non-negative integer in basic units @samp{u}) relative to upper edge
-of current page.
-
-@item v @var{n}
-Move @var{n}@tie{}basic units @samp{u} down (@var{n} is a non-negative
-integer).  The original @acronym{UNIX} troff manual allows negative
-values for @var{n} also, but @code{gtroff} doesn't use this.
-
-@item w
-Informs about a paddable white space to increase readability.
-The spacing itself must be performed explicitly by a move command.

-
-@node Graphics Commands, Device Control Commands, Simple Commands, Command Reference
-@subsubsection Graphics Commands
-
-Each graphics or drawing command in the intermediate output starts
-with the letter @samp{D}, followed by one or two characters that
-specify a subcommand; this is followed by a fixed or variable number
-of integer arguments that are separated by a single space character.
-A @samp{D} command may not be followed by another command on the same line
-(apart from a comment), so each @samp{D} command is terminated by a
-syntactical line break.
-
-@code{gtroff} output follows the classical spacing rules (no space
-between command and subcommand, all arguments are preceded by a
-single space character), but the parser allows optional space between
-the command letters and makes the space before the first argument
-optional.  As usual, each space can be any sequence of tab and space
-characters.
-
-Some graphics commands can take a variable number of arguments.
-In this case, they are integers representing a size measured in basic
-units @samp{u}.  The arguments called @var{h1}, @var{h2}, @dots{},
-@var{hn} stand for horizontal distances where positive means right,
-negative left.  The arguments called @var{v1}, @var{v2}, @dots{},
-@var{vn} stand for vertical distances where positive means down,
-negative up.  All these distances are offsets relative to the current
-location.
-
-Each graphics command directly corresponds to a similar @code{gtroff}
-@code{\D} escape sequence.  @xref{Drawing Requests}.
-
-Unknown @samp{D} commands are assumed to be device-specific.
-Its arguments are parsed as strings; the whole information is then
-sent to the postprocessor.
-
-In the following command reference, the syntax element
-@angles{line break} means a syntactical line break as defined above.
-
-@table @code
-@item D~ @var{h1} @var{v1} @var{h2} @var{v2} @dots{} @var{hn} @var{vn}@angles{line break}

-then to offset (@var{h2},@var{v2}), if given, etc.@: up to
-(@var{hn},@var{vn}).  This command takes a variable number of argument
-pairs; the current position is moved to the terminal point of the drawn
-curve.
-
-@item Da @var{h1} @var{v1} @var{h2} @var{v2}@angles{line break}
-Draw arc from current position to
-(@var{h1},@var{v1})@math{+}(@var{h2},@var{v2}) with center at

-@itemx DC @var{d} @var{dummy-arg}@angles{line break}
-Draw a solid circle using the current fill color with
-diameter@tie{}@var{d} (integer in basic units @samp{u}) with leftmost
-point at the current position; then move the current position to the
-rightmost point of the circle.  An optional second integer argument is
-ignored (this allows the formatter to generate an even number of
-arguments).  This command is a @code{gtroff} extension.
-
-@item Dc @var{d}@angles{line break}
-Draw circle line with diameter@tie{}@var{d} (integer in basic units
-@samp{u}) with leftmost point at the current position; then move the
-current position to the rightmost point of the circle.
-
-@item DE @var{h} @var{v}@angles{line break}
-Draw a solid ellipse in the current fill color with a horizontal
-diameter of@tie{}@var{h} and a vertical diameter of@tie{}@var{v} (both
-integers in basic units @samp{u}) with the leftmost point at the

-@item De @var{h} @var{v}@angles{line break}
-Draw an outlined ellipse with a horizontal diameter of@tie{}@var{h}
-and a vertical diameter of@tie{}@var{v} (both integers in basic units
-@samp{u}) with the leftmost point at current position; then move to
-the rightmost point of the ellipse.
-
-@item DF @var{color-scheme} @r{[}@var{component} @dots{}@r{]}@angles{line break}
-Set fill color for solid drawing objects using different color
-schemes; the analoguous command for setting the color of text, line
-graphics, and the outline of graphic objects is @samp{m}.
-The color components are specified as integer arguments between 0 and
-65536.  The number of color components and their meaning vary for the
-different color schemes.  These commands are generated by @code{gtroff}'s
-escape sequences @w{@code{\D'F @dots{}'}} and @code{\M} (with no other
-corresponding graphics commands).  No position changing.  This command
-is a @code{gtroff} extension.

-Set the color for filling solid drawing objects to a shade of gray,
-where 0 corresponds to solid white, 1000 (the default) to solid black,
-and values in between to intermediate shades of gray; this is
-obsoleted by command @samp{DFg}.
-
-@item @math{@var{n} < 0} or @math{@var{n} > 1000}
-Set the filling color to the color that is currently being used for

-drawn line.
-
-@item Dp @var{h1} @var{v1} @var{h2} @var{v2} @dots{} @var{hn} @var{vn}@angles{line break}
-Draw a polygon line from current position to offset (@var{h1},@var{v1}),
-from there to offset (@var{h2},@var{v2}), etc.@: up to offset
-(@var{hn},@var{vn}), and from there back to the starting position.
-For historical reasons, the position is changed by adding the sum of
-all arguments with odd index to the actual horizontal position and the
-even ones to the vertical position.  Although this doesn't make sense
-it is kept for compatibility.

-@node Device Control Commands, Obsolete Command, Graphics Commands, Command Reference
-@subsubsection Device Control Commands
-
-Each device control command starts with the letter @samp{x},
-followed by a space character (optional or arbitrary space or tab in
-@code{gtroff}) and a subcommand letter or word; each argument (if any)
-must be preceded by a syntactical space.  All @samp{x} commands are
-terminated by a syntactical line break; no device control command can
-be followed by another command on the same line (except a comment).
-
-The subcommand is basically a single letter, but to increase
-readability, it can be written as a word, i.e., an arbitrary sequence
-of characters terminated by the next tab, space, or newline character.
-All characters of the subcommand word but the first are simply ignored.
-For example, @code{gtroff} outputs the initialization command
-@w{@samp{x i}} as @w{@samp{x init}} and the resolution command
-@w{@samp{x r}} as @w{@samp{x res}}.
-
-In the following, the syntax element @angles{line break} means a
-syntactical line break (@pxref{Separation}).
-
-@table @code
-@item xF @var{name}@angles{line break}
-The @samp{F} stands for @var{Filename}.
-
-Use @var{name} as the intended name for the current file in error
-reports.  This is useful for remembering the original file name when
-@code{gtroff} uses an internal piping mechanism.  The input file is
-not changed by this command.  This command is a @code{gtroff} extension.
-
-@item xf @var{n} @var{s}@angles{line break}
-The @samp{f} stands for @var{font}.
-
-Mount font position@tie{}@var{n} (a non-negative integer) with font
-named@tie{}@var{s} (a text word).  @xref{Font Positions}.
-
-@item xH @var{n}@angles{line break}
-The @samp{H} stands for @var{Height}.
-
-Set glyph height to@tie{}@var{n} (a positive integer in scaled
-points @samp{z}).  @acronym{AT&T} @code{troff} uses the unit points
-(@samp{p}) instead.  @xref{Output Language Compatibility}.
-
-@item xi@angles{line break}
-The @samp{i} stands for @var{init}.
-
-Initialize device.  This is the third command of the prologue.
-
-@item xp@angles{line break}
-The @samp{p} stands for @var{pause}.
-
-Parsed but ignored.  The original @acronym{UNIX} troff manual writes
-
-@display
-pause device, can be restarted
-@end display
-
-@item xr @var{n} @var{h} @var{v}@angles{line break}
-The @samp{r} stands for @var{resolution}.
-
-Resolution is@tie{}@var{n}, while @var{h} is the minimal horizontal
-motion, and @var{v} the minimal vertical motion possible with this
-device; all arguments are positive integers in basic units @samp{u}
-per inch.  This is the second command of the prologue.
-
-@item xS @var{n}@angles{line break}
-The @samp{S} stands for @var{Slant}.
-
-Set slant to@tie{}@var{n} (an integer in basic units @samp{u}).
-
-@item xs@angles{line break}
-The @samp{s} stands for @var{stop}.
-
-Terminates the processing of the current file; issued as the last
-command of any intermediate troff output.
-
-@item xt@angles{line break}
-The @samp{t} stands for @var{trailer}.
-
-Generate trailer information, if any.  In @var{gtroff}, this is
-actually just ignored.
-
-@item xT @var{xxx}@angles{line break}
-The @samp{T} stands for @var{Typesetter}.
-
-Set name of device to word @var{xxx}, a sequence of characters ended
-by the next white space character.  The possible device names coincide
-with those from the @code{groff} @option{-T} option.  This is the first
-command of the prologue.
-
-@item xu @var{n}@angles{line break}
-The @samp{u} stands for @var{underline}.
-
-Configure underlining of spaces.  If @var{n} is@tie{}1, start
-underlining of spaces; if @var{n} is@tie{}0, stop underlining of spaces.
-This is needed for the @code{cu} request in nroff mode and is ignored
-otherwise.  This command is a @code{gtroff} extension.
-
-@item xX @var{anything}@angles{line break}
-The @samp{x} stands for @var{X-escape}.
-
-Send string @var{anything} uninterpreted to the device.  If the line
-following this command starts with a @samp{+} character this line is
-interpreted as a continuation line in the following sense.  The
-@samp{+} is ignored, but a newline character is sent instead to the
-device, the rest of the line is sent uninterpreted.  The same applies
-to all following lines until the first character of a line is not a
-@samp{+} character.  This command is generated by the @code{gtroff}
-escape sequence @code{\X}.  The line-continuing feature is a
-@code{gtroff} extension.

-
-@node Obsolete Command,  , Device Control Commands, Command Reference
-@subsubsection Obsolete Command
-In @acronym{AT&T} @code{troff} output, the writing of a single
-glyph is mostly done by a very strange command that combines a
-horizontal move and a single character giving the glyph name.  It
-doesn't have a command code, but is represented by a 3-character
-argument consisting of exactly 2@tie{}digits and a character.
-
-@table @asis
-@item @var{dd}@var{g}
-Move right @var{dd} (exactly two decimal digits) basic units @samp{u},
-then print glyph@tie{}@var{g} (represented as a single character).
-
-In @code{gtroff}, arbitrary syntactical space around and within this
-command is allowed to be added.  Only when a preceding command on the
-same line ends with an argument of variable length a separating space
-is obligatory.  In @acronym{AT&T} @code{troff}, large clusters of these
-and other commands are used, mostly without spaces; this made such output
-almost unreadable.
-@end table
-
-For modern high-resolution devices, this command does not make sense
-because the width of the glyphs can become much larger than two
-decimal digits.  In @code{gtroff}, this is only used for the devices
-@code{X75}, @code{X75-12}, @code{X100}, and @code{X100-12}.  For other
-devices, the commands @samp{t} and @samp{u} provide a better
-functionality.

-@node Output Language Compatibility,  , Intermediate Output Examples, gtroff Output
-@subsection Output Language Compatibility
-
-The intermediate output language of @acronym{AT&T} @code{troff}
-was first documented in the @acronym{UNIX} troff manual, with later
-additions documented in @cite{A Typesetter-indenpendent TROFF},
-written by Brian Kernighan.
-
-The @code{gtroff} intermediate output format is compatible with this
-specification except for the following features.
-
-@itemize @bullet
-@item
-The classical quasi device independence is not yet implemented.
-
-@item
-The old hardware was very different from what we use today.  So the
-@code{groff} devices are also fundamentally different from the ones in
-@acronym{AT&T} @code{troff}.  For example, the @acronym{AT&T}
-PostScript device is called @code{post} and has a resolution of only
-720 units per inch, suitable for printers 20 years ago, while
-@code{groff}'s @code{ps} device has a resolution of
-72000 units per inch.  Maybe, by implementing some rescaling
-mechanism similar to the classical quasi device independence,
-@code{groff} could emulate @acronym{AT&T}'s @code{post} device.
-
-@item
-The B-spline command @samp{D~} is correctly handled by the
-intermediate output parser, but the drawing routines aren't
-implemented in some of the postprocessor programs.
-
-@item
-The argument of the commands @samp{s} and @w{@samp{x H}} has the
-implicit unit scaled point @samp{z} in @code{gtroff}, while
-@acronym{AT&T} @code{troff} has point (@samp{p}).  This isn't an
-incompatibility but a compatible extension, for both units coincide
-for all devices without a @code{sizescale} parameter in the @file{DESC}
-file, including all postprocessors from @acronym{AT&T} and
-@code{groff}'s text devices.  The few @code{groff} devices with
-a @code{sizescale} parameter either do not exist for @acronym{AT&T}
-@code{troff}, have a different name, or seem to have a different
-resolution.  So conflicts are very unlikely.
-
-@item
-The position changing after the commands @samp{Dp}, @samp{DP}, and
-@samp{Dt} is illogical, but as old versions of @code{gtroff} used this
-feature it is kept for compatibility reasons.
-
-@ignore
-Temporarily, there existed some confusion on the positioning after the
-@samp{D} commands that are groff extensions.  This has been clarified
-by establishing the classical rule for all @code{groff} drawing commands:
-
-@itemize
-@item
-The position after a graphic object has been drawn is at its end;
-for circles and ellipses, the `end' is at the right side.
-
-@item
-From this, the positionings specified for the drawing commands above
-follow quite naturally.

-The @code{gtroff} font format is roughly a superset of the
-@code{ditroff} font format (as used in later versions of @acronym{AT&T}
-@code{troff} and its descendants).  Unlike the @code{ditroff} font
-format, there is no associated binary format; all files are text
-files.@footnote{Plan@tie{}9 @code{troff} has also abandoned the binary
-format.}  The font files for device @var{name} are stored in a directory
-@file{dev@var{name}}.  There are two types of file: a device description
-file called @file{DESC} and for each font@tie{}@var{f} a font file
-called@tie{}@file{@var{f}}.

-
-@item sizescale @var{n}
-@kindex sizescale
-The scale factor for point sizes.  By default this has a value of@tie{}1.
-One scaled point is equal to one point/@var{n}.  The arguments to the
-@code{unitwidth} and @code{sizes} commands are given in scaled points.
-@xref{Fractional Type Sizes}, for more information.
-
-@item unitwidth @var{n}
-@kindex unitwidth
-Quantities in the font files are given in machine units for fonts whose
-point size is @var{n}@tie{}scaled points.
-
-@item prepro @var{program}
-@kindex prepro
-Call @var{program} as a preprocessor.  Currently, this keyword is used
-by @code{groff} with option @option{-Thtml} only.
-
-@item postpro @var{program}
-@kindex postpro
-Call @var{program} as a postprocessor.  For example, the line
-
-@Example
-postpro grodvi
-@endExample
-
-@noindent
-in the file @file{devdvi/DESC} makes @code{groff} call @code{grodvi}
-if option @option{-Tdvi} is given (and @option{-Z} isn't used).
-
-@item tcommand
-@kindex tcommand
-This means that the postprocessor can handle the @samp{t} and @samp{u}
-intermediate output commands.
-
-@item sizes @var{s1} @var{s2} @dots{} @var{sn} 0
-@kindex sizes
-This means that the device has fonts at @var{s1}, @var{s2}, @dots{}
-@var{sn} scaled points.  The list of sizes must be terminated by@tie{}0
-(this is digit zero).  Each @var{si} can also be a range of sizes
-@var{m}-@var{n}.  The list can extend over more than one line.
-

-@var{S1} @dots{} @var{Sm}.
-
-@item fonts @var{n} @var{F1} @var{F2} @var{F3} @dots{} @var{Fn}
-@kindex fonts
-Fonts @var{F1} @dots{} @var{Fn} are mounted in the font positions
-@var{m}+1, @dots{}, @var{m}+@var{n} where @var{m} is the number of
-styles.  This command may extend over more than one line.  A font name
-of@tie{}0 means no font is mounted on the corresponding font position.
-
-@item family @var{fam}
-@kindex family
-The default font family is @var{fam}.
-
-@item use_charnames_in_special
-@kindex use_charnames_in_special
-This command indicates that @code{gtroff} should encode special
-characters inside special commands.  Currently, this is only used
-by the @acronym{HTML} output device.  @xref{Postprocessor Access}.
-
-@item papersize @var{string} @dots{}
-@kindex papersize
-Select a paper size.  Valid values for @var{string} are the ISO paper
-types @code{A0}-@code{A7}, @code{B0}-@code{B7}, @code{C0}-@code{C7},
-@code{D0}-@code{D7}, @code{DL}, and the US paper types @code{letter},
-@code{legal}, @code{tabloid}, @code{ledger}, @code{statement},
-@code{executive}, @code{com10}, and @code{monarch}.  Case is not significant
-for @var{string} if it holds predefined paper types.  Alternatively,
-@var{string} can be a file name (e.g.@: @file{/etc/papersize}); if the file
-can be opened, @code{groff} reads the first line and tests for the above
-paper sizes.  Finally, @var{string} can be a custom paper size in the format
-@code{@var{length},@var{width}} (no spaces before and after the comma).
-Both @var{length} and @var{width} must have a unit appended; valid values
-are @samp{i} for inches, @samp{C} for centimeters, @samp{p} for points, and
-@samp{P} for picas.  Example: @code{12c,235p}.  An argument which starts
-with a digit is always treated as a custom paper format.  @code{papersize}
-sets both the vertical and horizontal dimension of the output medium.
-
-More than one argument can be specified; @code{groff} scans from left to
-right and uses the first valid paper specification.
-
-@item pass_filenames
-@kindex pass_filenames
-Tell @code{gtroff} to emit the name of the source file currently
-being processed.  This is achieved by the intermediate output command
-@samp{F}.  Currently, this is only used by the @acronym{HTML} output
-device.
-
-@item print @var{program}

-Use @var{program} as a spooler program for printing.  If omitted,
-the @option{-l} and @option{-L} options of @code{groff} are ignored.

-followed by a sequence of lines.  Each line gives information for one
-glyph.  A line comprises a number of fields separated by blanks or
-tabs.  The format is

-@kindex ---
-@noindent
-@var{name} identifies the glyph name@footnote{The distinction between
-input, characters, and output, glyphs, is not clearly separated in the
-terminology of @code{groff}; for example, the @code{char} request
-should be called @code{glyph} since it defines an output entity.}:
-If @var{name} is a single character@tie{}@var{c} then it corresponds
-to the @code{gtroff} input character@tie{}@var{c}; if it is of the form
-@samp{\@var{c}} where @var{c} is a single character, then it
-corresponds to the special character @code{\[@var{c}]}; otherwise it
-corresponds to the special character @samp{\[@var{name}]}.  If it
-is exactly two characters @var{xx} it can be entered as
-@samp{\(@var{xx}}.  Note that single-letter special characters can't
-be accessed as @samp{\@var{c}}; the only exception is @samp{\-} which
-is identical to @code{\[-]}.
-
-@code{gtroff} supports 8-bit input characters; however some utilities
-have difficulties with eight-bit characters.  For this reason, there is
-a convention that the entity name @samp{char@var{n}} is equivalent to
-the single input character whose code is@tie{}@var{n}.  For example,
-@samp{char163} would be equivalent to the character with code@tie{}163
-which is the pounds sterling sign in the ISO@tie{}@w{Latin-1} character set.
-You shouldn't use @samp{char@var{n}} entities in font description files
-since they are related to input, not output.  Otherwise, you get
-hard-coded connections between input and output encoding which
-prevents use of different (input) character sets.
-
-The name @samp{---} is special and indicates that the glyph is
-unnamed; such glyphs can only be used by means of the @code{\N}
-escape sequence in @code{gtroff}.
-
-The @var{type} field gives the glyph type:
-
-@table @code
-@item 1
-the glyph has a descender, for example, @samp{p};
-
-@item 2
-the glyph has an ascender, for example, @samp{b};
-
-@item 3
-the glyph has both an ascender and a descender, for example, @samp{(}.
-@end table
-
-The @var{code} field gives the code which the postprocessor uses to
-print the glyph.  The glyph can also be input to @code{gtroff}
-using this code by means of the @code{\N} escape sequence.  @var{code}
-can be any integer.  If it starts with @samp{0} it is interpreted as
-octal; if it starts with @samp{0x} or @samp{0X} it is interpreted as
-hexadecimal.  Note, however, that the @code{\N} escape sequence only
-accepts a decimal integer.
-
-The @var{entity-name} field gives an @acronym{ASCII} string
-identifying the glyph which the postprocessor uses to print the
-@code{gtroff} glyph @var{name}.  This field is optional and has been
-introduced so that the @acronym{HTML} device driver can encode its
-character set.  For example, the glyph @samp{\[Po]} is
-represented as @samp{&pound;} in @acronym{HTML} 4.0.
-
-Anything on the line after the @var{entity-name} field resp.@: after
-@samp{--} will be ignored.
-
-The @var{metrics} field has the form:
-
-@display
-@group
-@var{width}[@code{,}@var{height}[@code{,}@var{depth}[@code{,}@var{italic-correction}
-  [@code{,}@var{left-italic-correction}[@code{,}@var{subscript-correction}]]]]]
-@end group
-@end display
-
-@noindent
-There must not be any spaces between these subfields (it has been split
-here into two lines for better legibility only).  Missing subfields are
-assumed to be@tie{}0.  The subfields are all decimal integers.  Since
-there is no associated binary format, these values are not required to
-fit into a variable of type @samp{char} as they are in @code{ditroff}.
-The @var{width} subfield gives the width of the glyph.  The @var{height}
-subfield gives the height of the glyph (upwards is positive); if a
-glyph does not extend above the baseline, it should be given a zero
-height, rather than a negative height.  The @var{depth} subfield gives
-the depth of the glyph, that is, the distance from the baseline to the
-lowest point below the baseline to which the glyph extends (downwards is
-positive); if a glyph does not extend below the baseline, it should be
-given a zero depth, rather than a negative depth.  The
-@var{italic-correction} subfield gives the amount of space that should
-be added after the glyph when it is immediately to be followed by a
-glyph from a roman font.  The @var{left-italic-correction} subfield
-gives the amount of space that should be added before the glyph when it
-is immediately to be preceded by a glyph from a roman font.  The
-@var{subscript-correction} gives the amount of space that should be
-added after a glyph before adding a subscript.  This should be less
-than the italic correction.
-
-A line in the @code{charset} section can also have the format
-
-@Example
-@var{name} "
-@endExample
-
-@noindent
-This indicates that @var{name} is just another name for the glyph
-mentioned in the preceding line.
-
-@kindex kernpairs
-The word @code{kernpairs} starts the kernpairs section.  This contains a
-sequence of lines of the form:
-
-@Example
-@var{c1} @var{c2} @var{n}
-@endExample
-
-@noindent
-This means that when glyph @var{c1} appears next to glyph @var{c2}
-the space between them should be increased by@tie{}@var{n}.  Most
-entries in the kernpairs section have a negative value for@tie{}@var{n}.

-This document describes
-the text processing facilities
-available on the \*U\(dg
-.(f
-\(dg\*U is a trademark
-of AT&T Bell Laboratories
-.)f
-operating system
-via \*G and the
-\-me
-macro package.
-It is assumed
-that the reader
-already is generally familiar
-with the \*U operating system
-and a text editor
-such as
-.b ex .
-This is intended to be a casual introduction,
-and
-as such not all material is covered.
-In particular,
-many variations and additional features
-of the \-me macro package
-are not explained.
-For a complete discussion of this
-and other issues,
-see
-.ul
-The \-me Reference Manual
-and
-.ul
-The \*N/\*T Reference Manual.
-.pp
-\*G, a computer program
-that runs on the \*U operating system,
-reads an input file
-prepared by the user
-and outputs a formatted paper
-suitable for publication or framing.
-The input consists of
-.i text ,
-or words to be printed,
-and
-.i requests ,
-which give instructions
-to the \*G program
-telling how to format the printed copy.
-.pp
-Section 1
-describes the basics
-of text processing.
-Section 2
-describes the basic requests.
-Section 3
-introduces displays.
-Annotations,
-such as footnotes,
-are handled in
-section 4.
-The more complex requests
-which are not discussed in section 2
-are covered in section 5.
-Finally,
-section 6
-discusses things you will need
-to know
-if you want to typeset documents.
-If you are a novice,
-you probably won't want to read beyond section 4
-until you have tried some of the basic features out.
-.pp
-When you have your raw text ready,
-call the \*G formatter by typing
-as a request to the \*U shell:
-.(b
-groff \-me \-T\c
-.i "type files"
-.)b
-where
-.i type
-describes the type of
-output device you are using.
-A complete description of options
-to the \*G command can be found in
-.b groff (1).
-.pp
-The word
-.i argument
-is used in this manual
-to mean a word or number
-which appears on the same line
-as a request
-which modifies the meaning
-of that request.
-For example,
-the request
-.(b
-\&.sp
-.)b
-spaces one line,
-but
-.(b
-\&.sp 4
-.)b
-spaces four lines.
-The number
-.b 4
-is an
-.i argument
-to the
-.b .sp
-request
-which says to space four lines
-instead of one.
-Arguments are separated from the request
-and from each other
-by spaces.
-.sh 1 "Basics of Text Processing"
-.pp
-The primary function
-of \*G
-is to
-.i collect
-words from input lines,
-.i fill
-output lines with those words,
-.i justify
-the right hand margin by inserting extra spaces
-in the line,
-and output the result.
-For example,
-the input:
-.(b
-Now is the time
-for all good men
-to come to the aid
-of their party.
-Four score and seven
-years ago,...
-.)b
-will be read,
-packed onto output lines,
-and justified
-to produce:
-.(b F
-Now is the time
-for all good men
-to come to the aid
-of their party.
-Four score and seven
-years ago,...
-.)b
-Sometimes you may want to start a new output line
-even though the line you are on
-is not yet full;
-for example,
-at the end of a paragraph.
-To do this
-you can cause a
-.i break ,
-which
-starts a new output line.
-Some requests
-cause a break automatically,
-as do blank input lines
-and input lines beginning with a space.
-.pp
-Not all input lines
-are text to be formatted.
-Some of the input lines
-are
-.i requests
-which describe
-how to format the text.
-Requests always have a period
-or an apostrophe
-(\c
-.q "\|\(aa\|" )
-as the first character
-of the input line.
-.pp
-The text formatter
-also does more complex things,
-such as automatically numbering pages,
-skipping over page folds,
-putting footnotes in the correct place,
-and so forth.
-.pp
-I can offer you a few hints
-for preparing text
-for input to \*G.
-First,
-keep the input lines short.
-Short input lines are easier to edit,
-and \*G will pack words onto longer lines
-for you anyhow.
-In keeping with this,
-it is helpful
-to begin a new line
-after every period,
-comma,
-or phrase,
-since common corrections
-are to add or delete sentences
-or phrases.
-Second,
-do not put spaces at the end of lines,
-since this can sometimes confuse the \*N
-processor.
-Third,
-do not hyphenate words at the end of lines
-(except words that should have hyphens in them,
-such as
-.q mother-in-law );
-\*G is smart enough to hyphenate words
-for you as needed,
-but is not smart enough
-to take hyphens out
-and join a word back together.
-Also,
-words such as
-.q mother-in-law
-should not be broken
-over a line,
-since then you will get a space
-where not wanted,
-such as
-.tr @-
-.nh
-.q "mother@\ in@law" .
-.br
-.tr @@
-.hy 14
-.sh 1 "Basic Requests"
-.sh 2 "Paragraphs"
-.pp
-Paragraphs are begun
-by using the
-.b .pp
-request.
-For example,
-the input:
-.(b
-\&.pp
-Now is the time for all good men
-to come to the aid of their party.
-Four score and seven years ago,...
-.)b
-produces a blank line
-followed by an indented first line.
-The result is:
-.(b F
-.ti +\n(piu
-Now is the time for all good men
-to come to the aid of their party.
-Four score and seven years ago,...
-.)b
-.pp
-Notice that the sentences
-of the paragraphs
-.i "must not"
-begin with a space,
-since blank lines
-and lines beginning with spaces
-cause a break.
-For example,
-if I had typed:
-.(b
-\&.pp
-Now is the time for all good men
-      to come to the aid of their party.
-Four score and seven years ago,...
-.)b
-The output would be:
-.(b F
-.ti +\n(piu
-Now is the time for all good men
-      to come to the aid of their party.
-Four score and seven years ago,...
-.)b
-A new line begins after the word
-.q men
-because the second line began with a space character.
-.pp
-There are many
-fancier
-types of paragraphs,
-which will be described later.
-.sh 2 "Headers and Footers"
-.pp
-Arbitrary headers and footers
-can be put
-at the top and bottom
-of every page.
-Two requests
-of the form
-.b .he \ \c
-.i title
-and
-.b .fo \ \c
-.i title
-define the titles to put at the head and the foot
-of every page,
-respectively.
-The titles are called
-.i three-part
-titles,
-that is,
-there is a left-justified part,
-a centered part,
-and a right-justified part.
-To separate these three parts
-the first character of
-.i title
-(whatever it may be)
-is used as a delimiter.
-Any character may be used,
-but
-backslash
-and double quote marks
-should be avoided.
-The percent sign
-is replaced by the current page number
-whenever found in the title.
-For example,
-the input:
-.(b
-\&.he \(aa\(aa%\(aa\(aa
-\&.fo \(aaJane Jones\(aa\(aaMy Book\(aa
-.)b
-results in the page number
-centered at the top
-of each page,
-.q "Jane Jones"
-in the lower left corner,
-and
-.q "My Book"
-in the lower right corner.
-.sh 2 "Double Spacing"
-.pp
-.ls 2
-\*G will double space output text automatically if you
-use the request
-.b ".ls\ 2" ,
-as is done in this section.
-You can revert to single spaced mode
-by typing
-.b ".ls\ 1" .
-.ls 1
-.sh 2 "Page Layout"
-.pp
-A number of requests allow
-you to change the way the printed copy looks,
-sometimes called the
-.i layout
-of the output page.
-Most of these requests adjust the placing
-of
-.q "white space"
-(blank lines or spaces).
-In these explanations,
-characters in italics
-should be replaced with values you wish to use;
-bold characters
-represent characters which should actually be typed.
-.pp
-The
-.b .bp
-request
-starts a new page.
-.pp
-The request
-.b .sp \ \c
-.i N
-leaves
-.i N
-lines of blank space.
-.i N
-can be omitted
-(meaning skip a single line)
-or can be of the form
-.i N \^\c
-.b i
-(for
-.i N
-inches)
-or
-.i N \^\c
-.b c
-(for
-.i N
-centimeters).
-For example, the input:
-.(b
-\&.sp 1.5i
-My thoughts on the subject
-\&.sp
-.)b
-leaves one and a half inches of space,
-followed by the line
-.q "My thoughts on the subject" ,
-followed by a single blank line.
-.pp
-The
-.b .in \ \c
-.i +N
-request
-changes the amount of white space
-on the left of the page
-(the
-.i indent ).
-The argument
-.i N
-can be of the form
-.b + \c
-.i N
-(meaning leave
-.i N
-spaces more than you are already leaving),
-.b \- \c
-.i N
-(meaning leave less than you do now),
-or just
-.i N
-(meaning leave exactly
-.i N
-spaces).
-.i N
-can be of the form
-.i N \^\c
-.b i
-or
-.i N \^\c
-.b c
-also.
-For example,
-the input:
-.(b
-initial text
-\&.in 5
-some text
-\&.in +1i
-more text
-\&.in \-2c
-final text
-.)b
-produces
-.q "some text"
-indented exactly five spaces
-from the left margin,
-.q "more text"
-indented five spaces
-plus one inch
-from the left margin
-(fifteen spaces
-on a pica typewriter),
-and
-.q "final text"
-indented five spaces
-plus one inch
-minus two centimeters
-from the margin.
-That is,
-the output is:
-.(b
-initial text
-.in +5
-some text
-.in +1i
-more text
-.in -2c
-final text
-.)b
-.pp
-The
-.b .ti \ \c
-.i +N
-(temporary indent)
-request is used like
-.b .in \ \c
-.i +N
-when the indent
-should apply to one line only,
-after which it should revert
-to the previous indent.
-For example,
-the input:
-.(b
-\&.in 1i
-\&.ti 0
-Ware, James R.  The Best of Confucius,
-Halcyon House, 1950.
-An excellent book containing translations of
-most of Confucius\(aa most delightful sayings.
-A definite must for anyone interested in the early foundations
-of Chinese philosophy.
-.)b
-produces:
-.in 1i+\n($iu
-.ti \n($iu
-Ware, James R.  The Best of Confucius,
-Halcyon House, 1950.
-An excellent book containing translations of
-most of Confucius' most delightful sayings.
-A definite must for anyone interested in the early foundations
-of Chinese philosophy.
-.pp
-Text lines can be centered
-by using the
-.b .ce
-request.
-The line after the
-.b .ce
-is centered
-(horizontally)
-on the page.
-To center more than one line,
-use
-.b .ce \ \c
-.i N
-(where
-.i N
-is the number of lines to center),
-followed by the
-.i N
-lines.
-If you want to center many lines
-but don't want to count them,
-type:
-.(b
-\&.ce 1000
-lines to center
-\&.ce 0
-.)b
-The
-.b ".ce\ 0"
-request tells \*G to center zero more lines,
-in other words,
-stop centering.
-.pp
-All of these requests
-cause a break;
-that is,
-they always start
-a new line.
-If you want to start a new line
-without performing any other action,
-use
-.b .br .
-.sh 1 "Displays"
-.pp
-Displays are sections of text
-to be set off
-from the body of the paper.
-Major quotes,
-tables,
-and figures
-are types of displays,
-as are all the examples
-used in this document.
-All displays
-except centered blocks
-are output
-single spaced.
-.sh 2 "Major Quotes"
-.pp
-Major quotes
-are quotes which are several lines long,
-and hence are set in from the rest
-of the text
-without quote marks
-around them.
-These can be generated
-using the commands
-.b .(q
-and
-.b .)q
-to surround the quote.
-For example,
-the input:
-.(b
-As Weizenbaum points out:
-\&.(q
-It is said that to explain is to explain away.
-This maxim is nowhere so well fulfilled
-as in the areas of computer programming,...
-\&.)q
-.)b
-generates as output:
-.lp
-As Weizenbaum points out:
-.(q
-It is said that to explain is to explain away.
-This maxim is nowhere so well fulfilled
-as in the areas of computer programming,...
-.)q
-.sh 2 "Lists"
-.pp
-A
-.i list
-is an indented,
-single spaced,
-unfilled display.
-Lists should be used
-when the material to be printed
-should not be filled and justified
-like normal text,
-such as columns of figures
-or the examples used in this paper.
-Lists are surrounded
-by the requests
-.b .(l
-and
-.b .)l .
-For example,
-type:
-.(b
-Alternatives to avoid deadlock are:
-\&.(l
-Lock in a specified order
-Detect deadlock and back out one process
-Lock all resources needed before proceeding
-\&.)l
-.)b
-will produce:
-.br
-Alternatives to avoid deadlock are:
-.(l
-Lock in a specified order
-Detect deadlock and back out one process
-Lock all resources needed before proceeding
-.)l
-.sh 2 "Keeps"
-.pp
-A
-.i keep
-is a display of lines
-which are kept on a single page
-if possible.
-An example of where you would use a keep
-might be a diagram.
-Keeps differ from lists
-in that lists may be broken
-over a page boundary
-whereas keeps will not.
-.pp
-Blocks are the basic kind of keep.
-They begin with the request
-.b .(b
-and end with the request
-.b .)b .
-If there is not room on the current page
-for everything in the block,
-a new page is begun.
-This has the unpleasant effect
-of leaving blank space
-at the bottom of the page.
-When this is not appropriate,
-you can use the alternative,
-called
-.i "floating keeps" .
-.pp
-.i "Floating keeps"
-move relative to the text.
-Hence,
-they are good for things
-which will be referred to
-by name,
-such as
-.q "See figure 3" .
-A floating keep will appear
-at the bottom of the current page
-if it will fit;
-otherwise,
-it will appear at the top
-of the next page.
-Floating keeps begin with the line
-.b .(z
-and end with the line
-.b .)z .
-For an example of a floating keep,
-see figure 1.
-.(z
-.in 1i
-.xl -1i
-.hl
-\&.(z
-\&.hl
-Text of keep to be floated.
-\&.sp
-\&.ce
-Figure 1.  Example of a Floating Keep.
-\&.hl
-\&.)z
-.sp
-.ce
-Figure 1.  Example of a Floating Keep.
-.hl
-.)z
-The
-.b .hl
-request is used
-to draw a horizontal line
-so that the figure
-stands out from the text.
-.sh 2 "Fancier Displays"
-.pp
-Keeps and lists are normally collected in
-.i nofill
-mode,
-so that they are good for tables and such.
-If you want a display
-in fill mode
-(for text),
-type
-.b ".(l\ F"
-(Throughout this section,
-comments applied to
-.b .(l
-also apply to
-.b .(b
-and
-.b .(z ).
-This kind of display
-will be indented from both margins.
-For example,
-the input:
-.(b
-\&.(l F
-And now boys and girls,
-a newer, bigger, better toy than ever before!
-Be the first on your block to have your own computer!
-Yes kids, you too can have one of these modern
-data processing devices.
-You too can produce beautifully formatted papers
-without even batting an eye!
-\&.)l
-.)b
-will be output as:
-.(b F
-And now boys and girls,
-a newer, bigger, better toy than ever before!
-Be the first on your block to have your own computer!
-Yes kids, you too can have one of these modern
-data processing devices.
-You too can produce beautifully formatted papers
-without even batting an eye!
-.)b
-.pp
-Lists and blocks are also normally indented
-(floating keeps are normally left justified).
-To get a left-justified list,
-type
-.b ".(l\ L" .
-To get a list centered
-line-for-line,
-type
-.b ".(l C" .
-For example,
-to get a filled,
-left justified list, enter:
-.(b
-\&.(l L F
-text of block
-\&.)l
-.)b
-The input:
-.(b
-\&.(l
-first line of unfilled display
-more lines
-\&.)l
-.)b
-produces the indented text:
-.(b
-first line of unfilled display
-more lines
-.)b
-Typing the character
-.b L
-after the
-.b .(l
-request produces the left justified result:
-.(b L
-first line of unfilled display
-more lines
-.)b
-Using
-.b C
-instead of
-.b L
-produces the line-at-a-time centered output:
-.(b C
-first line of unfilled display
-more lines
-.)b
-.pp
-Sometimes it may be
-that you want to center several lines
-as a group,
-rather than centering them
-one line at a time.
-To do this
-use centered blocks,
-which are surrounded by the requests
-.b .(c
-and
-.b .)c .
-All the lines are centered as a unit,
-such that the longest line is centered
-and the rest are
-lined up around that line.
-Notice that lines
-do not move
-relative to each other
-using centered blocks,
-whereas they do
-using the
-.b C
-argument to keeps.
-.pp
-Centered blocks are
-.i not
-keeps,
-and may be used
-in conjunction
-with keeps.
-For example,
-to center a group of lines
-as a unit
-and keep them
-on one page,
-use:
-.(b
-\&.(b L
-\&.(c
-first line of unfilled display
-more lines
-\&.)c
-\&.)b
-.)b
-to produce:
-.(b L
-.(c
-first line of unfilled display
-more lines
-.)c
-.)b
-If the block requests
-(\c
-.b .(b
-and
-.b .)b )
-had been omitted
-the result would have been the same,
-but with no guarantee
-that the lines of the centered block
-would have all been on one page.
-Note the use of the
-.b L
-argument to
-.b .(b ;
-this causes the centered block
-to center within the entire line
-rather than within the line
-minus the indent.
-Also,
-the center requests
-must
-be nested
-.i inside
-the keep requests.
-.sh 1 "Annotations"
-.pp
-There are a number of requests
-to save text
-for later printing.
-.i Footnotes
-are printed at the bottom of the current page.
-.i "Delayed text"
-is intended to be a variant form
-of footnote;
-the text is printed only 
-when explicitly called for,
-such as at the end of each chapter.
-.i Indexes
-are a type of delayed text
-having a tag
-(usually the page number)
-attached to each entry
-after a row of dots.
-Indexes are also saved
-until called for explicitly.
-.sh 2 "Footnotes"
-.pp
-Footnotes begin with the request
-.b .(f
-and end with the request
-.b .)f .
-The current footnote number is maintained
-automatically,
-and can be used by typing \e**,
-to produce a footnote number\**.
-.(f
-\**Like this.
-.)f
-The number is automatically incremented
-after every footnote.
-For example,
-the input:
-.(b
-\&.(q
-A man who is not upright
-and at the same time is presumptuous;
-one who is not diligent and at the same time is ignorant;
-one who is untruthful and at the same time is incompetent;
-such men I do not count among acquaintances.\e**
-\&.(f
-\e**James R. Ware,
-\&.ul
-The Best of Confucius,
-Halcyon House, 1950.
-Page 77.
-\&.)f

-.)b
-generates the result:
-.(q
-A man who is not upright
-and at the same time is presumptuous;
-one who is not diligent and at the same time is ignorant;
-one who is untruthful and at the same time is incompetent;
-such men I do not count among acquaintances.\**
-.(f
-\**James R. Ware,
-.ul
-The Best of Confucius,
-Halcyon House, 1950.
-Page 77.
-.)f
-.)q
-It is important
-that the footnote
-appears
-.i inside
-the quote,
-so that you can be sure
-that the footnote
-will appear
-on the same page
-as the quote.
-.sh 2 "Delayed Text"
-.pp
-Delayed text
-is very similar to a footnote
-except that it is printed
-when called for explicitly.
-This allows a list of
-references to
-appear
-(for example)
-at the end of each chapter,
-as is the convention in some disciplines.
-Use
-.b \e*#
-on delayed text
-instead of
-.b \e**
-as on footnotes.
-.pp
-If you are using delayed text
-as your standard reference mechanism,
-you can still use footnotes,
-except that you may want to reference them
-with special characters*
-.(f
-*Such as an asterisk.
-.)f
-rather than numbers.
-.sh 2 "Indexes"
-.pp
-An
-.q index
-(actually more like a table of contents,
-since the entries are not sorted alphabetically)
-resembles delayed text,
-in that it is saved until called for.
-However,
-each entry has the page number
-(or some other tag)
-appended to the last line
-of the index entry
-after a row of dots.
-.pp
-Index entries begin with the request
-.b .(x
-and end with
-.b .)x .
-The
-.b .)x
-request may have a argument,
-which is the value to print
-as the
-.q "page number" .
-It defaults to the current page number.
-If the page number given is an underscore
-(\c
-.q _ )
-no page number
-or line of dots
-is printed at all.
-To get the line of dots
-without a page number,
-type
-.b ".)x """"" ,
-which specifies an explicitly null page number.
-.pp
-The
-.b .xp
-request prints the index.
-.pp
-For example,
-the input:
-.(b
-\&.(x
-Sealing wax
-\&.)x
-\&.(x
-Cabbages and kings
-\&.)x _
-\&.(x
-Why the sea is boiling hot
-\&.)x 2.5a
-\&.(x
-Whether pigs have wings
-\&.)x ""
-\&.(x
-This is a terribly long index entry, such as might be used
-for a list of illustrations, tables, or figures; I expect it to
-take at least two lines.
-\&.)x
-\&.xp
-.)b
-generates:
-.(x
-Sealing wax
-.)x
-.(x
-Cabbages and kings
-.)x _
-.(x
-Why the sea is boiling hot
-.)x 2.5a
-.(x

-This is a terribly long index entry, such as might be used
-for a list of illustrations, tables, or figures; I expect it to
-take at least two lines.
-.)x
-.xp
-.pp
-The
-.b .(x
-request may have a single character
-argument,
-specifying the
-.q name
-of the index;
-the normal index is
-.b x .
-Thus,
-several
-.q indices
-may be maintained simultaneously
-(such as a list of tables, table of contents, etc.).
-.pp
-Notice that the index must be printed
-at the
-.i end
-of the paper,
-rather than at the beginning
-where it will probably appear
-(as a table of contents);
-the pages may have to be physically rearranged
-after printing.
-.sh 1 "Fancier Features"
-.pp
-A large number of fancier requests
-exist,
-notably requests to provide other sorts of paragraphs,
-numbered sections of the form
-.b 1.2.3
-(such as used in this document),
-and multicolumn output.
-.sh 2 "More Paragraphs"
-.pp
-Paragraphs generally start with
-a blank line
-and with the first line
-indented.
-It is possible to get
-left-justified block-style paragraphs
-by using
-.b .lp
-instead of
-.b .pp ,
-as demonstrated by the next paragraph.
-.lp
-Sometimes you want to use paragraphs
-that have the
-.i body
-indented,
-and the first line
-exdented
-(opposite of indented)
-with a label.
-This can be done with the
-.b .ip
-request.
-A word specified on the same line as
-.b .ip
-is printed in the margin,
-and the body is lined up
-at a prespecified position
-(normally five spaces).
-For example,
-the input:
-.(b
-\&.ip one
-This is the first paragraph.
-Notice how the first line
-of the resulting paragraph lines up
-with the other lines in the paragraph.
-\&.ip two
-And here we are at the second paragraph already.
-You may notice that the argument to \c
-.b .ip
-appears
-in the margin.
-\&.lp
-We can continue text...
-.)b
-produces as output:
-.ip one
-This is the first paragraph.
-Notice how the first line of the resulting paragraph lines up
-with the other lines in the paragraph.
-.ip two
-And here we are at the second paragraph already.
-You may notice that the argument to
-.b .ip
-appears
-in the margin.
-.lp
-We can continue text without starting a new indented
-paragraph
-by using the
-.b .lp
-request.
-.pp
-If you have spaces in the label of a
-.b .ip
-request,
-you must use an
-.q "unpaddable space"
-instead of a regular space.
-This is typed as a backslash character
-(\c
-.q \e )
-followed by a space.
-For example,
-to print the label
-.q "Part 1" ,
-enter:
-.(b
-\&.ip "Part\e 1"
-.)b
-.pp
-If a label of an indented paragraph
-(that is, the argument to
-.b .ip )
-is longer than the space allocated for the label,
-.b .ip
-will begin a new line after the label.
-For example,
-the input:
-.(b
-\&.ip longlabel
-This paragraph had a long label.
-The first character of text on the first line
-will not line up with the text on second and subsequent lines,
-although they will line up with each other.
-.)b
-will produce:
-.ip longlabel
-This paragraph had a long label.
-The first character of text on the first line
-will not line up with the text on second and subsequent lines,
-although they will line up with each other.
-.pp
-It is possible to change the size of the label
-by using a second argument
-which is the size of the label.
-For example,
-the above example could be done correctly
-by saying:
-.(b
-\&.ip longlabel 10
-.)b
-which will make the paragraph indent
-10 spaces for this paragraph only.
-If you have many paragraphs to indent
-all the same amount,
-use the
-.i "number register"
-.b ii .
-For example, to leave one inch of space
-for the label,
-type:
-.(b
-\&.nr ii 1i
-.)b
-somewhere before the first call to
-.b .ip .
-Refer to the reference manual
-for more information.
-.pp
-If
-.b .ip
-is used
-with no argument at all
-no hanging tag will be printed.
-For example,
-the input:
-.(b
-\&.ip [a]
-This is the first paragraph of the example.
-We have seen this sort of example before.
-\&.ip
-This paragraph is lined up with the previous paragraph,
-but it has no tag in the margin.
-.)b
-produces as output:
-.ip [a]
-This is the first paragraph of the example.
-We have seen this sort of example before.
-.ip
-This paragraph is lined up with the previous paragraph,
-but it has no tag in the margin.
-.pp
-A special case of
-.b .ip
-is
-.b .np ,
-which automatically
-numbers paragraphs sequentially from 1.
-The numbering is reset at the next
-.b .pp ,
-.b .lp ,
-or
-.b .sh
-(to be described in the next section)
-request.
-For example,
-the input:
-.(b
-\&.np
-This is the first point.
-\&.np
-This is the second point.
-Points are just regular paragraphs
-which are given sequence numbers automatically
-by the .np request.
-\&.pp
-This paragraph will reset numbering by .np.
-\&.np
-For example,
-we have reverted to numbering from one now.
-.)b
-generates:
-.np
-This is the first point.
-.np
-This is the second point.
-Points are just regular paragraphs
-which are given sequence numbers automatically
-by the .np request.
-.pp
-This paragraph will reset numbering by .np.
-.np
-For example,
-we have reverted to numbering from one now.
-.pp
-The
-.b .bu
-request gives lists of this sort that are identified with
-bullets rather than numbers.
-The paragraphs are also crunched together.
-For example,
-the input:
-.(b
-\&.bu
-\&One egg yolk
-\&.bu
-\&One tablespoon cream or top milk
-\&.bu
-\&Salt, cayenne, and lemon juice to taste
-\&.bu
-\&A generous two tablespoonfuls of butter
-.)b
-produces\**:
-.(f
-\**By the way,
-if you put the first three ingredients in a a heavy, deep pan
-and whisk the ingredients madly over a medium flame
-(never taking your hand off the handle of the pot)
-until the mixture reaches the consistency of custard
-(just a minute or two),
-then mix in the butter off-heat,
-you will have a wonderful Hollandaise sauce.
-.)f

-One egg yolk

-.sh 2 "Section Headings"
-.pp
-Section numbers
-(such as the ones used in this document)
-can be automatically generated
-using the
-.b .sh
-request.
-You must tell
-.b .sh
-the
-.i depth
-of the section number
-and a section title.
-The depth
-specifies how many numbers
-are to appear
-(separated by decimal points)
-in the section number.
-For example,
-the section number
-.b 4.2.5
-has a depth of three.
-.pp
-Section numbers
-are incremented
-in a fairly intuitive fashion.
-If you add a number
-(increase the depth),
-the new number starts out
-at one.
-If you subtract section numbers
-(or keep the same number)
-the final number is incremented.
-For example,
-the input:
-.(b
-\&.sh 1 "The Preprocessor"
-\&.sh 2 "Basic Concepts"
-\&.sh 2 "Control Inputs"
-\&.sh 3
-\&.sh 3
-\&.sh 1 "Code Generation"
-\&.sh 3
-.)b
-produces as output the result:
-.(b
-.b
-1.  The Preprocessor
-1.1.  Basic Concepts
-1.2.  Control Inputs
-1.2.1.
-1.2.2.
-2.  Code Generation
-2.1.1.
-.)b
-.pp
-You can specify the section number to begin
-by placing the section number after the section title,
-using spaces instead of dots.
-For example,
-the request:
-.(b
-\&.sh 3 "Another section" 7 3 4
-.)b
-will begin the section numbered
-.b 7.3.4 ;
-all subsequent
-.b .sh
-requests will number relative to this number.
-.pp
-There are more complex features
-which will cause each section to be indented
-proportionally to the depth of the section.
-For example, if you enter:
-.(b
-\&.nr si \c
-.i N
-.)b
-each section will be indented by an amount
-.i N .
-.i N
-must have a scaling factor attached,
-that is, it must be of the form
-.i Nx ,
-where
-.i x
-is a character telling what units
-.i N
-is in.
-Common values for
-.i x
-are
-.b i
-for inches,
-.b c
-for centimeters,
-and
-.b n
-for
-.i ens
-(the width of a single character).
-For example,
-to indent each section
-one-half inch,
-type:
-.(b
-\&.nr si 0.5i
-.)b
-After this,
-sections will be indented by
-one-half inch
-per level of depth in the section number.
-For example,
-this document was produced
-using the request
-.(b
-\&.nr si 3n
-.)b
-at the beginning of the input file,
-giving three spaces of indent
-per section depth.
-.pp
-Section headers without automatically generated numbers
-can be done using:
-.(b
-\&.uh "Title"
-.)b
-which will do a section heading,
-but will put no number on the section.
-.sh 2 "Parts of the Basic Paper"
-.pp
-There are some requests
-which assist in setting up
-papers.
-The
-.b .tp
-request
-initializes for a title page.
-There are no headers or footers
-on a title page,
-and unlike other pages
-you can space down
-and leave blank space
-at the top.
-For example,
-a typical title page might appear as:
-.(b
-\&.tp
-\&.sp 2i
-\&.(l C
-THE GROWTH OF TOENAILS
-IN UPPER PRIMATES
-\&.sp
-by
-\&.sp
-Frank N. Furter
-\&.)l
-\&.bp
-.)b
-.pp
-The
-.b .+c \ \c
-.i T
-request can be used
-to start chapters.
-Each chapter is automatically numbered
-from one,
-and a heading is printed at the top of each chapter
-with the chapter number
-and the chapter name
-.i T .
-For example,
-to begin a chapter called
-.q Conclusions ,
-use the request:
-.(b
-\&.+c "CONCLUSIONS"
-.)b
-which will produce,
-on a new page,
-the lines
-.(b C
-CHAPTER 5
-CONCLUSIONS
-.)b
-with appropriate spacing for a thesis.
-Also, the header is moved to the foot of the page
-on the first page of a chapter.
-Although the
-.b .+c
-request was not designed to work only with the
-.b .th
-request,
-it is tuned for the format acceptable
-for a PhD thesis
-at Berkeley.
-.pp
-If the
-title parameter
-.i T
-is omitted from the
-.b .+c
-request,
-the result is a chapter with no heading.
-This can also be used at the beginning
-of a paper;
-for example,
-.b .+c
-was used to generate page one
-of this document.
-.pp
-Although
-papers traditionally have the abstract,
-table of contents,
-and so forth at the front of the paper,
-it is more convenient to format
-and print them last
-when using \*G.
-This is so that index entries
-can be collected and then printed
-for the table of contents
-(or whatever).
-At the end of the paper,
-issue the
-.b ".++ P"
-request,
-which begins the preliminary part
-of the paper.
-After issuing this request,
-the
-.b .+c
-request will begin a preliminary section
-of the paper.
-Most notably,
-this prints the page number
-restarted from one
-in lower case Roman numbers.
-.b .+c
-may be used repeatedly
-to begin different parts of the
-front material
-for example,
-the abstract,
-the table of contents,
-acknowledgments,
-list of illustrations,
-etc.
-The request
-.b ".++ B"
-may also be used
-to begin the bibliographic section
-at the end of the paper.
-For example,
-the paper might appear
-as outlined in figure 2.
-(In this figure,
-comments begin with the sequence

-.sh 2 "Equations and Tables"
-.pp
-Two special \*U programs exist
-to format special types of material.
-.b Eqn
-sets equations.
-.b Tbl
-arranges to print
-extremely pretty tables
-in a variety of formats.
-This document will only describe
-the embellishments
-to the standard features;
-consult the reference manuals
-for those processors
-for a description of their use.
-.pp
-The
-.b eqn
-program is described fully
-in the document
-.ul
-Typesetting Mathematics \- User's Guide
-by Brian W. Kernighan
-and Lorinda L. Cherry.
-Equations are centered,
-and are kept on one page.
-They are introduced by the
-.b .EQ
-request and terminated by the
-.b .EN
-request.
-.pp
-The
-.b .EQ
-request may take an
-equation number as an
-optional argument,
-which is printed vertically centered
-on the right hand side
-of the equation.
-If the equation becomes too long
-it should be split
-between two lines.
-To do this, type:
-.(b
-\&.EQ (eq 34)
-text of equation 34
-\&.EN C
-\&.EQ
-continuation of equation 34
-\&.EN
-.)b
-The
-.b C
-on the
-.b .EN
-request
-specifies that the equation
-will be continued.
-.pp
-The
-.b tbl
-program produces tables.
-It is fully described
-(including numerous examples)
-in the document
-.ul
-Tbl \- A Program to Format Tables
-by M. E. Lesk.
-Tables begin with the
-.b .TS
-request
-and end with the
-.b .TE
-request.
-Tables are normally kept on a single page.
-If you have a table which is too big
-to fit on a single page,
-so that you know it will extend
-to several pages,
-begin the table with the request
-.b ".TS\ H"
-and put the request
-.b .TH
-after the part of the table
-which you want
-duplicated at the top of every page
-that the table is printed on.
-For example, a table definition
-for a long table might look like:
-.ds TA \|\h'.4n'\v'-.2n'\s-4\zT\s0\v'.2n'\h'-.4n'\(ci\|
-.if n .ds TA \ \o'-T'\ \"
-.(b

-.pp
-.sh 2 "Two Column Output"
-.pp
-You can get two column output
-automatically
-by using the request
-.b .2c .
-This causes everything after it
-to be output in two-column form.
-The request
-.b .bc
-will start a new column;
-it differs from
-.b .bp
-in that
-.b .bp
-may leave a totally blank column
-when it starts a new page.
-To revert to single column output,
-use
-.b .1c .
-.sh 2 "Defining Macros"
-.pp
-A
-.i macro
-is a collection of requests and text
-which may be used
-by stating a simple request.
-Macros begin with the line
-.b ".de" \ \c
-.i xx
-(where
-.i xx
-is the name of the macro to be defined)
-and end with the line consisting of two dots.
-After defining the macro,
-stating the line
-.b . \c
-.i xx
-is the same as stating all the other lines.
-For example,
-to define a macro
-that spaces 3 lines
-and then centers the next input line,
-enter:
-.(b
-\&.de SS
-\&.sp 3
-\&.ce
-\&..
-.)b
-and use it by typing:
-.(b
-\&.SS
-\&Title Line
-(beginning of text)
-.)b
-.pp
-Macro names may be one or two characters.
-In order to avoid conflicts
-with names in \-me,
-always use upper case letters as names.
-The only names to avoid are
-.b TS ,
-.b TH ,
-.b TE ,
-.b EQ ,
-and
-.b EN .
-.sh 2 "Annotations Inside Keeps"
-.pp
-Sometimes you may want to put
-a footnote
-or index entry inside a keep.
-For example,
-if you want to maintain a
-.q "list of figures"
-you will want to do something like:
-.(b
-\&.(z
-\&.(c
-text of figure
-\&.)c
-\&.ce
-Figure 5.
-\&.(x f
-Figure 5
-\&.)x
-\&.)z
-.)b
-which you may hope
-will give you a figure
-with a label
-and an entry in the index
-.b f
-(presumably a list of figures index).
-Unfortunately,
-the
-index entry
-is read and interpreted
-when the keep is read,
-not when it is printed,
-so the page number in the index is likely to be wrong.
-The solution is to use the magic string
-.b \e!
-at the beginning of all the lines dealing with the index.
-In other words,
-you should use:
-.(b
-\&.(z
-\&.(c
-Text of figure
-\&.)c
-\&.ce
-Figure 5.
-\e!.(x f
-\e!Figure 5
-\e!.)x
-\&.)z
-.)b
-which will defer the processing of the index
-until the figure is output.
-This will guarantee
-that the page number in the index
-is correct.
-The same comments apply
-to
-blocks
-(with
-.b .(b
-and
-.b .)b )
-as well.
-.sh 1 "\*T and the Photosetter"
-.pp
-With a little care,
-you can prepare
-documents that
-will print nicely
-on either a regular terminal
-or when phototypeset
-using the \*T formatting program.
-.sh 2 "Fonts"
-.pp
-A
-.i font
-is a style of type.
-There are three fonts
-that are available simultaneously,
-Times Roman,
-Times Italic,
-and Times Bold,
-plus the special math font.
-The normal font is Roman.
-.pp
-There are ways of switching between fonts.
-The requests
-.b .r ,
-.b .i ,
-.b .b ,
-and
-.b .bi
-switch to Roman,
-italic,
-bold,
-and bold-italic fonts respectively.
-You can set a single word
-in some font
-by typing (for example):
-.(b
-\&.i word
-.)b
-which will set
-.i word
-in italics
-but does not affect the surrounding text.
-.pp
-Notice that if you are setting more than one word
-in whatever font,
-you must surround that word with double quote marks
-(`\|"\|')
-so that it will appear to the \*G processor as a single word.
-The quote marks will not appear in the formatted text.
-If you do want a quote mark to appear,
-you should quote the entire string
-(even if a single word),
-and use
-.i two
-quote marks where you want one to appear.
-For example,
-if you want to produce the text:
-.(b
-.i """Master Control\|"""
-.)b
-in italics, you must type:
-.(b
-\&.i """Master Control\e|"""
-.)b
-The
-.b \e|
-produces a very narrow space
-so that the
-.q l
-does not overlap the quote sign in \*G,
-like this:
-.(b
-.i """Master Control"""
-.)b
-.pp
-There are also some
-.q pseudo-fonts
-available.
-The input:
-.(b
-\&.(b
-\&.u underlined
-\&.bx "words in a box"
-\&.)b
-.)b
-generates
-.(b
-.u underlined
-.bx "words in a box"
-.)b
-Notice that pseudo font requests
-set only the single parameter in the pseudo font;
-ordinary font requests will begin setting all text
-in the special font
-if you do not provide a parameter.
-No more than one word
-should appear
-with these three font requests
-in the middle of lines.
-This is because
-of the way \*G justifies text.
-For example,
-if you were to issue the requests:
-.(b
-\&.u "some bold italics"
-and
-\&.bx "words in a box"
-.)b
-in the middle of a line
-\*G would produce
-.u "some bold italics"
-and
-.bx "words in a box" ,\p
-which I think you will agree does not look good.
-.pp
-The second parameter
-of all font requests
-is set in the original font.
-For example,
-the font request:
-.(b
-\&.b bold face
-.)b
-generates
-.q bold
-in bold font,
-but sets
-.q face
-in the font of the surrounding text,
-resulting in:
-.(b
-.b bold face.
-.)b
-To set the two words
-.b bold
-and
-.b face
-both in
-.b "bold face" ,
-type:
-.(b
-\&.b "bold face"
-.)b
-.pp
-You can mix fonts in a word by using the
-special sequence
-.b \ec
-at the end of a line
-to indicate
-.q "continue text processing" ;
-this allows input lines
-to be joined together
-without a space between them.
-For example, the input:
-.(b
-\&.u under \ec
-\&.i italics
-.)b
-generates
-.u under \c
-.i italics ,
-but if we had typed:
-.(b
-\&.u under
-\&.i italics
-.)b
-the result would have been
-.u under
-.i italics
-as two words.
-.sh 2 "Point Sizes"
-.pp
-The phototypesetter
-supports different sizes of type,
-measured in points.
-The default point size
-is 10 points
-for most text,
-8 points for footnotes.
-To change the pointsize,
-type:
-.(b
-\&.sz \c
-.i +N
-.)b
-where
-.i N
-is the size wanted in points.
-The
-.i "vertical spacing"
-(distance between the bottom of most letters
-(the
-.i baseline )
-between adjacent lines)
-is set to be proportional
-to the type size.
-.pp
-These pointsize changes are
-.i temporary !!!
-For example,
-to reset the pointsize of basic text to twelve point, use:
-.(b
-\&.nr pp 12
-\&.nr sp 12
-\&.nr tp 12
-.)b
-to reset the default pointsize of
-paragraphs,
-section headers,
-and titles respectively.
-If you only want to set the names of sections in a larger pointsize,
-use:
-.(b
-\&.nr sp 11
-.)b
-alone \*- this sets section titles
-(e.g.,
-.b "Point Sizes"
-above)
-in a larger font than the default.
-.pp
-A single word or phrase can be set in a smaller pointsize
-than the surrounding text
-using the
-.b .sm
-request.
-This is especially convenient for words that are all capitals,
-due to the optical illusion that makes them look even larger
-than they actually are.
-For example:
-.(b
-\&.sm UNIX
-.)b
-prints as
-.sm UNIX
-rather than
-UNIX.
-.pp
-Warning:
-changing point sizes
-on the phototypesetter
-is a slow mechanical operation.
-On laser printers it may require loading new fonts.
-Size changes
-should be considered carefully.
-.sh 2 "Quotes"
-.pp
-It is conventional when using
-the typesetter to
-use pairs of grave and acute accents
-to generate double quotes,
-rather than the
-double quote character
-(`\|"\|').
-This is because it looks better
-to use grave and acute accents;
-for example, compare
-"quote" to
-``quote''.
-.pp
-You may use the sequences
-.b \e*(lq
-and
-.b \e*(rq
-to stand for the left and right quote
-respectively.
-For example,
-use:
-.(b
-\e*(lqSome things aren\(aat true

-.pp
-This document describes
-in extremely terse form
-the features
-of the
-.b \-me
-macro package
-for \*G.
-Some familiarity is assumed
-with
-\*G.
-Specifically,
-the reader should understand
-breaks,
-fonts,
-pointsizes,
-the use and definition of number registers
-and strings,
-how to define macros,
-and scaling factors for ens, points,
-.b v 's
-(vertical line spaces),
-etc.
-.pp
-For a more casual introduction
-to text processing
-using \*G,
-refer to the document
-.ul
-Writing Papers with \*G using \-me.
-.pp
-There are a number of macro parameters
-that may be adjusted.
-Fonts may be set to a font number only.
-Font 0 is no font change;
-the font of the surrounding text
-is used instead.
-Notice that font 0 is a
-.q pseudo-font ;
-that is,
-it is simulated by the macros.
-This means that although it is legal to set a font register
-to zero,
-it is not legal to use the escape character form,
-such as:
-.(b
-\ef0
-.)b
-.pp
-All distances
-are in basic units,
-so it is nearly always necessary
-to use a scaling factor.
-For example,
-the request
-to set the paragraph indent
-to eight one-en spaces is:
-.(b
-\&.nr pi 8n
-.)b
-and not
-.(b
-\&.nr pi 8
-.)b
-which would set the paragraph indent to eight basic units,
-or about 0.02 inch.
-Default parameter values are given in brackets
-in the remainder of this document.
-.pp
-Registers and strings
-of the form
-.b $ \c
-.i x
-may be used in expressions
-but should not be changed.
-Macros of the form
-.b $ \c
-.i x
-perform some function
-(as described)
-and may be redefined
-to change this function.
-This may be a sensitive operation;
-look at the body of the original macro
-before changing it.
-.pp
-All names in \-me
-follow a rigid naming convention.
-The user may define number registers,
-strings,
-and macros,
-provided that s/he
-uses single character upper case names
-or double character names
-consisting of letters and digits,
-with at least one upper case letter.
-In no case should special characters
-be used in user-defined names.
-Locally defined macros
-should all be of the form
-.b .* \c
-.i X ,
-where
-.i X
-is any letter
-(upper or lower case)
-or digit.
-.pp
-This documentation applies to \*G version
-\*(MO
-of the \-me macros.
-.sh 1 "Paragraphing"
-.pp
-These macros are used
-to begin paragraphs.
-The standard paragraph macro
-is
-.b .pp ;
-the others are all variants
-to be used for special purposes.
-.pp
-After the first call to one of the paragraphing macros
-defined in this section
-or the
-.b .sh
-macro
-(defined in the next session),
-the effects of changing parameters
-which will have a global effect
-on the format of the page
-(notably page length and header and footer margins)
-are not well defined
-and should be avoided.
-.TL
-.b .lp
-.DE
-Begin left-justified paragraph.
-Centering and underlining
-are turned off if they were on,
-the font is set to
-.NR (pf
-[1]
-the type size
-is set to
-.NR (pp
-[10p],
-and a
-.NR (ps
-space is inserted
-before the paragraph
-[0.35v]
-The indent is reset
-to
-.NR ($i
-[0]
-plus
-.NR (po
-[0]
-unless the paragraph
-is inside a display.
-(see
-.b .ba ).
-At least
-the first two lines
-of the paragraph
-are kept together
-on a page.
-.TL
-.b .pp
-.DE
-Like
-.b .lp ,
-except that it puts
-.NR (pi
-[5n]
-units of indent.
-This is the standard paragraph macro.
-.TL
-.b .ip
-.i T
-.i I
-.DE
-Indented paragraph
-with hanging tag.
-The body of the following paragraph
-is indented
-.i I
-spaces
-(or
-.NR (ii
-[5n]
-spaces
-if
-.i I
-is not specified)
-more than a non-indented paragraph
-(such as with
-.b .pp )
-is.
-The title
-.i T
-is exdented (opposite of indented).
-The result is a paragraph
-with an even left edge
-and
-.i T
-printed in the margin.
-Any spaces in
-.i T
-must be unpaddable.
-If
-.i T
-will not fit in the space provided,
-.b .ip
-will start a new line.
-.TL
-.b .np
-.DE
-A variant of .ip which numbers paragraphs.
-Numbering is reset
-after a
-.b .lp ,
-.b .pp ,
-or
-.b .sh .
-The current paragraph number
-is in
-.NR ($p .
-.TL
-.b .bu
-.DE
-Like
-.b .np
-except that paragraphs are marked with bullets (\(bu).
-Leading space is eliminated to create compact lists.
-.sh 1 "Section Headings"
-.pp
-Numbered sections
-are similar to paragraphs
-except that a
-section number
-is automatically
-generated for each one.
-The section numbers are of the form
-.b 1.2.3 .
-The
-.i depth
-of the section
-is the count of numbers
-(separated by decimal points)
-in the section number.
-.pp
-Unnumbered section headings are similar,
-except that no number is attached
-to the heading.
-.TL
-.b .sh
-.i +N
-.i T
-.i "a b c d e f"
-.DE
-Begin numbered section
-of depth
-.i N .
-If
-.i N
-is missing
-the current depth
-(maintained in
-the number register
-.NR ($0 )
-is used.
-The values of
-the individual parts of the section number
-are maintained in
-.NR ($1
-through
-.NR ($6 .
-There is a
-.NR (ss
-[1v]
-space before the section.
-.i T
-is printed
-as a section title
-in font
-.NR (sf
-[8]
-and size
-.NR (sp
-[10p].
-The
-.q name
-of the section may be accessed via
-.ST ($n .
-If
-.NR (si
-is non-zero,
-the base indent
-is set to
-.NR (si
-times the section depth,
-and the section title
-is exdented.
-(See
-.b .ba .)
-Also,
-an additional indent of
-.NR (so
-[0]
-is added to the section title
-(but not to the body of the section).
-The font is then set
-to the paragraph font,
-so that more information may occur
-on the line
-with the section number
-and title.
-.b .sh
-insures that there is enough room
-to print the section head
-plus the beginning of a paragraph
-(about 3 lines total).
-If
-.i a
-through
-.i f
-are specified,
-the section number is set to that number
-rather than incremented automatically.
-If any of
-.i a
-through
-.i f
-are a hyphen
-that number is not reset.
-If
-.i T
-is a single underscore
-(\c
-.q _ )
-then the section depth and numbering is reset,
-but the base indent is not reset
-and nothing is printed out.
-This is useful to automatically
-coordinate section numbers with
-chapter numbers.
-.TL
-.b .sx
-.i +N
-.DE
-Go to section depth
-.i N
-[\c
-.b \-1 ],
-but do not print the number
-and title,
-and do not increment the section number
-at level
-.i N .
-This has the effect
-of starting a new paragraph
-at level
-.i N .
-.TL
-.b .uh
-.i T
-.DE
-Unnumbered section heading.
-The title
-.i T
-is printed
-with the same rules for spacing,
-font, etc.,
-as for
-.b .sh .
-.TL
-.b .$p
-.i T
-.i B
-.i N
-.DE
-Print section heading.
-May be redefined
-to get fancier headings.
-.i T
-is the title passed on the
-.b .sh
-or
-.b .uh
-line;
-.i B
-is the section number for this section,
-and
-.i N
-is the depth of this section.
-These parameters are not always present;
-in particular,
-.b .sh
-passes all three,
-.b .uh
-passes only the first,
-and
-.b .sx
-passes three,
-but the first two
-are null strings.
-Care should be taken if this macro
-is redefined;
-it is quite complex and subtle.
-.TL
-.b .$0
-.i T
-.i B
-.i N
-.DE
-This macro is called automatically
-after every call to
-.b .$p .
-It is normally undefined,
-but may be used
-to automatically put
-every section title
-into the table of contents
-or for some similar function.
-.i T
-is the section title
-for the section title which was just printed,
-.i B
-is the section number,
-and
-.i N
-is the section depth.
-.TL
-.b .$1
-\-
-.b .$6
-.DE
-Traps called just before printing that depth section.
-May be defined to
-(for example)
-give variable spacing
-before sections.
-These macros are called from
-.b .$p ,
-so if you redefine that macro
-you may lose this feature.
-.sh 1 "Headers and Footers"
-.ds TP \fI\(aal\|\(aam\^\(aar\^\(aa\fP
-.pp
-Headers and footers
-are put at the top and bottom
-of every page
-automatically.
-They are set in font
-.NR (tf
-[3]
-and size
-.NR (tp
-[10p].
-Each of the definitions
-apply as of the
-.i next
-page.
-Three-part titles
-must be quoted
-if there are two blanks adjacent
-anywhere in the title
-or more than eight blanks total.
-.pp
-The spacing
-of headers and footers
-are controlled by three number registers.
-.NR (hm
-[4v]
-is the distance from the top of the page
-to the top of the header,
-.NR (fm
-[3v]
-is the distance from the bottom of the page
-to the bottom of the footer,
-.NR (tm
-[7v]
-is the distance from the top of the page
-to the top of the text,
-and
-.NR (bm
-[6v]
-is the distance from the bottom of the page
-to the bottom of the text
-(nominal).
-The macros
-.b .m1 ,
-.b .m2 ,
-.b .m3 ,
-and
-.b .m4
-are also supplied for compatibility
-with
-\s-1ROFF\s0 documents.

-[4v].
-.TL
-.b .ep
-.DE
-End this page,
-but do not begin the next page.
-Useful for forcing out footnotes,
-but other than
-that hardly every used.
-Must be followed by a
-.b .bp
-or the end of input.
-.TL
-.b .$h
-.DE
-Called at every page
-to print the header.
-May be redefined
-to provide fancy
-(e.g.,
-multi-line)
-headers,
-but doing so
-loses the function of the
-.b .he ,
-.b .fo ,
-.b .eh ,
-.b .oh ,
-.b .ef ,
-and
-.b .of
-requests,
-as well as the chapter-style title feature
-of
-.b .+c .
-.TL
-.b .$f
-.DE
-Print footer;
-same comments apply
-as in
-.b .$h .
-.TL
-.b .$H
-.DE
-A normally undefined macro
-which is called
-at the top of each page
-(after putting out
-the header,
-initial saved floating keeps,
-etc.);
-in other words,
-this macro is called immediately before
-printing text
-on a page.
-It can be used for column headings
-and the like.
-.sh 1 "Displays"
-.pp
-All displays except centered blocks
-and block quotes
-are preceded and followed
-by an extra
-.NR (bs
-[same as
-.NR (ps ]
-space.
-Quote spacing is stored in a separate register;
-centered blocks have no default initial or trailing space.
-The vertical spacing of all displays except quotes
-and centered blocks
-is stored in register
-.NR ($V
-instead of
-.NR ($v .
-.TL
-.b .(l
-.i m
-.i f
-.DE
-Begin list.
-Lists are single spaced,
-unfilled text.
-If
-.i f

-.b F ,
-the list will be filled.
-If
-.i m
-[\c
-.b I ]
-is
-.b I
-the list is indented by
-.NR (bi
-[4m];
-if
-.b M
-the list is indented to the left margin;
-if
-.b L
-the list is left justified with respect to the text
-(different from
-.b M
-only if the base indent
-(stored in
-.NR ($i
-and set with
-.b .ba )
-is not zero);
-and if
-.b C
-the list is centered on a line-by-line basis.
-The list is set in font
-.NR (df
-[0].
-Must be matched by a
-.b .)l .
-This macro is almost like
-.b .(b
-except that no attempt is made
-to keep the display on one page.
-.TL
-.b .)l
-.DE
-End list.
-.TL
-.b .(q
-.DE
-Begin major quote.
-These are single spaced,

-.NR (qp
-[one point smaller than surrounding text].
-.TL
-.b .)q
-.DE
-End major quote.
-.TL
-.b .(b
-.i m
-.i f
-.DE
-Begin block.
-Blocks are a form of
-.i keep ,
-where the text of a keep
-is kept together on one page
-if possible
-(keeps are useful
-for tables and figures
-which should not be broken
-over a page).
-If the block will not fit
-on the current page
-a new page is begun,
-.i unless
-that would leave more than
-.NR (bt
-[0]
-white space
-at the bottom of the text.
-If
-.NR (bt
-is zero, the threshold feature
-is turned off.
-Blocks are not filled
-unless
-.i f
-is
-.b F ,
-when they are filled.
-The block will be left-justified
-if
-.i m
-is
-.b L ,
-indented by
-.NR (bi
-[4m]
-if
-.i m
-is
-.b I
-or absent,
-centered
-(line-for-line)
-if
-.i m
-is
-.b C ,
-and left justified to the margin
-(not to the base indent)
-if
-.i m
-is
-.b M .
-The block is set in font
-.NR (df
-[0].
-.TL
-.b .)b
-.DE
-End block.
-.TL
-.b .(z
-.i m
-.i f
-.DE
-Begin floating keep.
-Like
-.b .(b
-except that the keep is
-.i floated
-to the bottom of the page
-or the top of the next page.
-Therefore,
-its position relative to the text changes.
-The floating keep is preceded and followed
-by
-.NR (zs
-[1v]
-space.
-Also,
-it defaults to mode
-.b M .
-.TL
-.b .)z
-.DE
-End floating keep.
-.TL
-.b .(c
-.DE
-Begin centered block.
-The next keep
-is centered as a block,
-rather than on a line-by-line basis
-as with
-.b ".(b C" .
-This call may be nested
-inside keeps.
-.TL
-.b .)c
-.DE
-End centered block.
-.sh 1 Annotations
-.TL
-.b .(d
-.DE
-Begin delayed text.
-Everything in the next keep
-is saved for output
-later with
-.b .pd ,
-in a manner
-similar to footnotes.
-.TL
-.b .)d
-.i n
-.DE
-End delayed text.
-The delayed text number register
-.NR ($d
-and the associated string
-.ST #
-are incremented if
-.ST #
-has been referenced.
-.TL
-.b .pd
-.DE
-Print delayed text.
-Everything diverted via
-.b .(d
-is printed and truncated.
-This might be used
-at the end of each chapter.
-.TL
-.b .(f
-.DE
-Begin footnote.
-The text of the footnote
-is floated to the bottom
-of the page
-and set in font
-.NR (ff
-[1]
-and size
-.NR (fp
-[8p].
-Each entry
-is preceded by
-.NR (fs
-[0.2v]
-space,
-is indented
-.NR (fi
-[3n]
-on the first line,
-and is indented
-.NR (fu
-[0]
-from the right margin.
-Footnotes line up underneath
-two column output.
-If the text of the footnote
-will not all fit on one page
-it will be carried over
-to the next page.
-.TL
-.b .)f
-.i n
-.DE
-End footnote.
-The number register
-.NR ($f
-and the associated string
-.ST *
-are incremented
-if they have been referenced.
-.TL
-.b .$s
-.DE
-The macro to output the footnote separator.
-This macro may be redefined
-to give other size lines or other types
-of separators.
-Currently
-it draws a 1.5i line.
-.TL
-.b .(x
-.i x
-.DE
-Begin index entry.
-Index entries are saved in the index
-.i x
-[\c
-.b x ]
-until called up with
-.b .xp.
-Each entry is preceded
-by a
-.NR (xs
-[0.2v]
-space.
-Each entry is
-.q undented
-by
-.NR (xu
-[0.5i];
-this register tells how far the page number
-extends into the right margin.
-.TL
-.b .)x
-.i P
-.i A
-.DE
-End index entry.
-The index entry
-is finished with a row of dots
-with
-.i A
-[null]
-right justified on the last line
-(such as for an author's name),
-followed by P
-[\c
-.NR % ].
-If
-.i A
-is specified,
-.i P
-must be specified;
-.NR %
-can be used to print the current page number.
-If
-.i P
-is an underscore,
-no page number
-and no row of dots
-are printed.
-.TL
-.b .xp
-.i x
-.DE
-Print index
-.i x
-[\c
-.b x ].
-The index is formatted in the font, size, and so forth
-in effect at the time it is printed,
-rather than at the time it is collected.
-.sh 1 "Columned Output"
-.TL
-.b .2c
-.i +S
-.i N
-.DE
-Enter two-column mode.
-The column separation is set to
-.i +S
-[4n, 0.5i in ACM mode]
-(saved in
-.NR ($s ).
-The column width,
-calculated to fill the single column line length
-with both columns,
-is stored in
-.NR ($l .
-The current column
-is in
-.NR ($c .
-You can test register
-.NR ($m
-[1]
-to see if you are in single column
-or double column mode.
-Actually,
-the request enters
-.i N
-[2]
-column output.
-.TL
-.b .1c
-.DE
-Revert to single-column mode.
-.TL
-.b .bc
-.DE
-Begin column.
-This is like
-.b .bp
-except that it begins a new column
-on a new page
-only if necessary,
-rather than forcing a whole new page
-if there is another column left
-on the current page.
-.sh 1 "Fonts and Sizes"
-.TL
-.b .sz
-.i +P
-.DE
-The pointsize is set to
-.i P
-[10p],
-and the line spacing is set proportionally.
-The line spacing as a percentage of the pointsize expressed in units
-is stored in
-.NR ($v .

-The \fBpic\fP language is a \fBtroff\fP extension that makes it easy
-to create and alter box-and-arrow diagrams of the kind frequently used
-in technical papers and textbooks.  This paper is both an introduction
-to and reference for \fIgpic\/\fP(1), the implementation distributed by
-the Free Software Foundation for use with \fIgroff\/\fP(1).
-.AE

-.NH 1
-Introduction to PIC
-.
-.NH 2
-Why PIC?
-.PP
-The \fBpic\fP language provides an easy way to write procedural
-box-and-arrow diagrams to be included in \fBtroff\fP documents.  The
-language is sufficiently flexible to be quite useful for state charts,
-Petri-net diagrams, flow charts, simple circuit schematics, jumper
-layouts, and other kinds of illustration involving repetitive uses of
-simple geometric forms and splines.  Because these descriptions are
-procedural and object-based, they are both compact and easy to modify.
-.PP
-The \fIgpic\/\fP(1) implementation of \fBpic\fP is distributed by the
-Free Software Foundation for use with their \fIgroff\/\fP(1)
-implementation of \fBtroff\fP.  Because both implementations are
-widely available in source form for free, they are good bets for
-writing very portable documentation.
-.
-.NH 2
-PIC Versions
-.PP
-The original 1984 pre-\fIditroff\/\fP(1) version of \fBpic\fP is long
-obsolete.  The rewritten 1991 version is still available as part of
-the Documenter's Work Bench module of System V.
-.PP
-Where differences between Documenter's Work Bench (1991) \fBpic\fP and GNU
-\fBpic\fP need to be described, original \fBpic\fP is referred to as
-\[lq]DWB pic\[rq].  Details on the history of the program are given at the
-end of this document.
-.PP
-In this document, the \fIgpic\/\fP(1) extensions will be marked as such.
-.
-.
-.NH 1
-Invoking PIC
-.PP
-Every \fBpic\fP description is a little program, which gets compiled
-by \fIpic\/\fP(1) into \fIgtroff\/\fP(1) macros.  Programs that process or
-display \fIgtroff\/\fP(1) output need not know or care that parts of the
-image began life as \fBpic\fP descriptions.
-.PP
-The \fIpic\/\fP(1) program tries to translate anything between \fB.PS\fP
-and \fB.PE\fP markers, and passes through everything else.  The normal
-definitions of \fB.PS\fP and \fB.PE\fP in the \fIms\fP macro package
-and elsewhere have also the side-effect of centering the \fBpic\fP output
-on the page.
-.
-.NH 2
-PIC Error Messages
-.PP
-If you make a \fBpic\fP syntax error, \fIgpic\/\fP(1) will issue an
-error message in the standard \fIgcc\/\fP(1)-like syntax.  A typical
-error message looks like this,
-.KS
-.DS
-.CW
-pic:pic.ms:<nnn>: parse error before `<token>'
-pic:pic.ms:<nnn>: giving up on this picture
-.DE
-.R
-.KE
-.LP
-where \[la]nnn\[ra] is a line number, and \[la]token\[ra] is a token near (usually
-just after) the error location.
-.
-.
-.NH 1
-Basic PIC Concepts
-.PP
-Pictures are described procedurally, as collections of objects
-connected by motions.  Normally, \fBpic\fP tries to string together
-objects left-to-right in the sequence they are described, joining them
-at visually natural points.  Here is an example illustrating the
-flow of data in \fBpic\fP processing:
-.KS
-.PS
-ellipse "document";
-arrow;
-box width 0.6 "\fIgpic\/\fP(1)"
-arrow;
-box width 1.1 "\fIgtbl\/\fP(1) or \fIgeqn\/\fP(1)" "(optional)" dashed;
-arrow;
-box width 0.6 "\fIgtroff\/\fP(1)";
-arrow;
-ellipse "PostScript"
-.PE
-.CE "1: Flow of \fBpic\fP data"
-.PP
-This was produced from the following \fBpic\fP program:
-.KS
-.DS
-.ps -1
-.vs -1
-.CW
-\&.PS
-ellipse "document";
-arrow;
-box width 0.6 "\efIpic\e/\efP(1)"
-arrow;
-box width 1.1 "\efIgtbl\e/\efP(1) or \efIgeqn\e/\efP(1)" "(optional)" dashed;
-arrow;
-box width 0.6 "\efIgtroff\e/\efP(1)";
-arrow;
-ellipse "PostScript"
-\&.PE
-.DE
-.R
-.KE
-.LP
-This little program illustrates several \fBpic\fP basics.  Firstly, we
-see how to invoke three object types; ellipses, arrows, and boxes.  We
-see how to declare text lines to go within an object (and that text
-can have font changes in it).  We see how to change the line style of
-an object from solid to dashed.  And we see that a box can be made
-wider than its default size to accommodate more text (we'll discuss
-this facility in detail in the next section).
-.PP
-We also get to see \fBpic\fP's simple syntax.  Statements are ended by
-newlines or semicolons.  String quotes are required around all text
-arguments, whether or not they contain spaces.  In general, the order
-of command arguments and modifiers like \[lq]width 1.2\[rq] or
-\[lq]dashed\[rq] doesn't matter, except that the order of text arguments
-is significant.
-.PP
-Here are all but one of the basic \fBpic\fP objects at their default sizes:
-.KS
-.PS
-box "box";
-move;
-line "line" "";
-move;
-arrow "arrow" "";
-move;
-circle "circle";
-move;
-ellipse "ellipse";
-move;
-arc; down; move; "arc"
-.PE
-.CE "2: Basic \fBpic\fP objects"
-.PP
-The missing simple object type is a \fIspline\fP.  There is also a way
-to collect objects into \fIblock composites\fP which allows you to
-treat the whole group as a single object (resembling a box) for many
-purposes.  We'll describe both of these later on.
-.PP
-The box, ellipse, circle, and block composite objects are \fIclosed\/\fR;
-lines, arrows, arcs and splines are \fIopen\fP.  This distinction
-will often be important in explaining command modifiers.
-.PP
-Figure \n[H1]-2 was produced by the following \fBpic\fP program,
-which introduces some more basic concepts:
-.KS
-.DS
-.CW
-\&.PS
-box "box";
-move;
-line "line" "";
-move;
-arrow "arrow" "";
-move;
-circle "circle";
-move;
-ellipse "ellipse";
-move;
-arc; down; move; "arc"
-\&.PE
-.DE
-.ft R
-.KE
-.PP
-The first thing to notice is the \fImove\fP command, which moves a
-default distance (1/2 inch) in the current movement direction.
-.PP
-Secondly, see how we can also decorate lines and arrows with text.
-The line and arrow commands each take two arguments here, specifying
-text to go above and below the object.  If you wonder why one argument
-would not do, contemplate the output of \fBarrow "ow!"\fP:
-.KS
-.PS
-arrow "ow!"
-.PE
-.CE "3: Text centered on an arrow"
-.PP
-When a command takes one text string, \fBpic\fP tries to place it at
-the object's geometric center.  As you add more strings, \fBpic\fP
-treats them as a vertical block to be centered.  The program
-.KS
-.DS
-.CW
-line "1";
-line "1" "2";
-line "1" "2" "3";
-line "1" "2" "3" "4";
-line "1" "2" "3" "4" "5";
-.DE
-.ft R
-.KE
-.LP
-for example, gives you this:
-.KS
-.sp 2
-.PS
-line "1";
-line "1" "2";
-line "1" "2" "3";
-line "1" "2" "3" "4";
-line "1" "2" "3" "4" "5";
-.PE
-.sp 2
-.CE "4: Effects of multiple text arguments"
-.PP
-The last line of Figure 3.2's program, `\fBarc; down; move;
-"arc"\fP', describing the captioned arc, introduces several new ideas.
-Firstly, we see how to change the direction in which objects are
-joined.  Had we written \fBarc; move; "arc"\fP,
-omitting \fBdown\fP the caption would have been joined to the top
-of the arc, like this:
-.KS
-.PS
-arc; move; "arc";
-.PE
-.CE "5: Result of \fBarc; move; \"arc\"\fP"
-.PP
-This is because drawing an arc changes the default direction to the
-one its exit end points at.  To reinforce this point, consider:
-.KS
-.PS
-arc cw; move; "arc";
-.PE
-.CE "6: Result of \fBarc cw; move; \"arc\"\fP"
-.PP
-All we've done differently here is specify \[lq]cw\[rq] for a clockwise arc
-(\[lq]ccw\[rq] specifies counter-clockwise direction).
-Observe how it changes the default direction to down, rather than up.
-.PP
-Another good way to see this via with the following program:
-.KS
-.DS
-.CW
-line; arc; arc cw; line
-.DE
-.ft R
-.KE
-.LP
-which yields:
-.KS
-.PS
-line; arc; arc cw; line;
-.PE
-.CE "7: Result of \fBline; arc; arc cw; line\fP"
-.LP
-Notice that we did not have to specify \[lq]up\[rq] for the second arc to be
-joined to the end of the first.
-.PP
-Finally, observe that a string, alone, is treated as text to be
-surrounded by an invisible box of a size either specified by width
-and height attributes or by the defaults \fBtextwid\fR and
-\fBtextht\fR.  Both are initially zero (because we don't know the
-default font size).
-.
-.
-.NH 1 
-Sizes and Spacing
-.PP
-Sizes are specified in inches.  If you don't like inches, it's
-possible to set a global style variable \fBscale\fP that changes the
-unit.  Setting \fBscale = 2.54\fP will effectively change the internal
-unit to centimeters (all other size variable values will be scaled
-correspondingly).
-.
-.NH 2
-Default Sizes of Objects
-.PP
-Here are the default sizes for \fBpic\fP objects:
-.TS H
-center, tab(@), linesize(2);
-lb | lb
-l | l.
-.sp 2p
-Object@Default Size
-.sp 2p
-_
-.sp 2p
-.TH
-box@0.75" wide by 0.5" high
-circle@0.5" diameter
-ellipse@0.75" wide by 0.5" high
-arc@0.5" radius
-line@0.5" long
-arrow@0.5" long
-.sp 5p
-_
-.TE
-.PP
-The simplest way to think about these defaults is that they make the
-other basic objects fit snugly into a default-sized box.
-.
-.NH 2
-Objects Do Not Stretch!
-.PP
-Text is rendered in the current font with normal troff line spacing.
-Boxes, circles, and ellipses do \fInot\fP automatically resize to fit
-enclosed text.  Thus, if you say \fBbox "this text far too long for a
-default box"\fP you'll get this:
-.KS
-.PS
-box "this text is far too long for a default box"
-.PE
-.CE "1: Boxes do not automatically resize"
-.LP
-which is probably not the effect you want.
-.
-.NH 2
-Resizing Boxes
-.PP
-To change the box size, you can specify a box width with the \[lq]width\[rq]
-modifier:
-.KS
-.PS
-box width 3 "this text is far too long for a default box"
-.PE
-.CE "2: Result of \fBbox width 3 \"text far too long\"\fP"
-.PP
-This modifier takes a dimension in inches.  There is also a \[lq]height\[rq]
-modifier that will change a box's height.  The \fBwidth\fP keyword may
-be abbreviated to \fBwid\fP; the \fBheight\fP keyword to \fBht\fP.
-.
-.NH 2
-Resizing Other Object Types
-.PP
-To change the size of a circle, give it a \fBrad[ius]\fP or
-\fBdiam[eter]\fP modifier; this changes the radius or diameter of the
-circle, according to the numeric argument that follows.
-.KS
-.PS
-{circle rad 0.1; move down 0.2 from last circle .s; "0.1"};
-move; circle rad 0.2 "0.2"; move; circle rad 0.3 "0.3";
-.PE
-.CE "3: Circles with increasing radii"
-.PP
-The \fBmove\fP command can also take a dimension, which just tells
-it how many inches to move in the current direction.
-.PP
-Ellipses are sized to fit in the rectangular box defined by their
-axes, and can be resized with \fBwidth\fP and \fBheight\fP like boxes.
-.PP
-You can also change the radius of curvature of an arc with \fBrad[ius]\fP
-(which specifies the radius of the circle of which the arc is a segment).
-Larger values yield flatter arcs.
-.KS
-.PS
-{arc rad 0.1; move down 0.3 from last arc .center; "0.1"};
-move;
-{arc rad 0.2; move down 0.4 from last arc .center; "0.2"};
-move;
-{arc rad 0.3; move down 0.5 from last arc .center; "0.3"};
-.PE
-.CE "4: \fBarc rad\fP with increasing radii"
-.PP
-Observe that because an arc is defined as a quarter circle, increasing
-the radius also increases the size of the arc's bounding box.
-.
-.NH 2
-The `same' Keyword
-.PP
-In place of a dimension specification, you can use the keyword
-\fBsame\fR.  This gives the object the same size as the previous one
-of its type.  As an example, the program
-.KS
-.DS
-.CW
-\&.PS
-box; box wid 1 ht 1; box same; box
-\&.PE
-.R
-.DE
-.KE
-.LP
-gives you

-.PE
-.CE "5: The \fBsame\fP keyword"
-.
-.
-.NH 1
-Generalized Lines and Splines
-.
-.NH 2
-Diagonal Lines
-.PP
-It is possible to specify diagonal lines or arrows by adding multiple \fBup\fP,
-\fBdown\fP, \fBleft\fP, and \fBright\fP modifiers to the line object.
-Any of these can have a multiplier.  To understand the effects, think
-of the drawing area as being gridded with standard-sized boxes.
-.KS

-.PP
-A \[lq]line\[rq] or \[lq]arrow\[rq] object may actually be a path
-consisting of any number of segments of varying lengths and directions.
-To describe a path, connect several line or arrow commands with the

-.NH 1
-Decorating Objects
-.
-.NH 2
-Dashed Objects
-.PP
-We've already seen that the modifier \fBdashed\fP can change the line
-style of an object from solid to dashed.  GNU \fBgpic\fP permits you to
-dot or dash ellipses, circles, and arcs (and splines in \*[tx] mode
-only); some versions of DWB may only permit dashing of lines and
-boxes.  It's possible to change the dash interval by specifying a
-number after the modifier.
-.PP
-.KS
-.PS
-box dashed "default";
-move;
-box dashed 0.05 "0.05";
-move;
-box dashed 0.1 "0.1";

-move;
-box dashed 0.2 "0.2";
-.PE
-.CE "1: Dashed objects"
-.
-.NH 2
-Dotted Objects
-.PP
-Another available qualifier is \fBdotted\fP.  GNU \fBgpic\fP permits
-you to dot or dash ellipses, circles, and arcs (and splines in \*[tx]
-mode only); some versions of DWB may only permit dashing of lines and
-boxes.  It too can be suffixed with a number to specify the interval
-between dots:
-.KS
-.PS
-box dotted "default";
-move;
-box dotted 0.05 "0.05";
-move;
-box dotted 0.1 "0.1";
-move;
-box dotted 0.15 "0.15";
-move;
-box dotted 0.2 "0.2";
-.PE
-.CE "2: Dotted objects"
-.
-.NH 2
-Rounding Box Corners
-.PP
-It is also possible, in GNU \fBgpic\fP only, to modify a box so it has
-rounded corners:
-.KS
-.PS
-box rad 0.05 "rad 0.05";
-move;
-box rad 0.1 "rad 0.1";
-move;
-box rad 0.15 "rad 0.15"; 
-move;
-box rad 0.2 "rad 0.2"; 
-move;
-box rad 0.25 "rad 0.25"; 
-.PE
-.CE "3: \fBbox rad\fP with increasing radius values"
-.PP
-Radius values higher than half the minimum box dimension are silently
-truncated to that value.
-.
-.NH 2
-Arrowheads
-.PP
-Lines and arcs can be decorated as well.  Any line or arc (and any
-spline as well) can be decorated with arrowheads by adding one or more
-as modifiers:
-.KS
-.PS
-line <- ->
-.PE
-.CE "4: Double-headed line made with  \fBline <- ->\fP"
-.PP
-In fact, the \fBarrow\fP command is just shorthand for \fBline ->\fP.  And
-there is a double-head modifier <->, so the figure above could have been made
-with \fBline <->\fP.
-.PP
-Arrowheads have a \fBwidth\fP attribute, the distance across the rear;
-and a \fBheight\fP attribute, the length of the arrowhead along the shaft.
-.PP
-Arrowhead style is controlled by the style variable \fBarrowhead\fP.
-The DWB and GNU versions interpret it differently.  DWB defaults to
-open arrowheads and an \fBarrowhead\fP value of\~2; the Kernighan
-paper says a value of\~7 will make solid arrowheads.  GNU \fBgpic\fP
-defaults to solid arrowheads and an \fBarrowhead\fP value of\~1; a
-value of\~0 will produce open arrowheads.  Note that solid arrowheads are
-always filled with the current outline color.
-.
-.NH 2
-Line Thickness
-.PP
-It's also possible to change the line thickness of an object (this is
-a GNU extension, DWB \fBpic\fP doesn't support it).  
-The default thickness of the lines used to draw objects is controlled by the
-.B linethick
-variable.
-This gives the thickness of lines in points.
-A negative value means use the default thickness:
-in \*[tx] output mode, this means use a thickness of 8 milliinches;
-in \*[tx] output mode with the
-.B -c
-option, this means use the line thickness specified by
-.B .ps
-lines; in troff output mode, this means use a thickness proportional
-to the pointsize.  A zero value means draw the thinnest possible line
-supported by the output device.  Initially it has a value of -1.
-There is also a \fBthickness\fP attribute (which can be abbreviated to
-\fBthick\fP).  For example, \fBcircle thickness 1.5\fP would draw a
-circle using a line with a thickness of 1.5 points.  The thickness of
-lines is not affected by the value of the
-.B scale
-variable, nor by any width or height given in the
-.B .PS
-line.
-.
-.NH 2
-Invisible Objects
-.PP
-The modifier \fBinvis[ible]\fP makes an object entirely invisible.  This
-used to be useful for positioning text in an invisible object that is
-properly joined to neighboring ones.  Newer DWB versions and GNU
-\fBpic\fP treat stand-alone text in exactly this way.
-.
-.NH 2
-Filled Objects
-.PP
-It is possible to fill boxes, circles, and ellipses.  The
-modifier \fBfill[ed]\fP accomplishes this.  You can suffix it with a fill
-value; the default is given by the stule variable \fBfillval\fP.
-.PP
-DWB \fBpic\fP and \fBgpic\fP have opposite conventions for fill values
-and different defaults.  DWB \fBfillval\fP defaults to 0.3 and smaller
-values are darker; GNU \fBfillval\fP uses 0 for white and 1 for black.
-.KS
-.PS
-circle fill; move; circle fill 0.4; move; circle fill 0.9;
-.PE
-.CE "5: \fBcircle fill; move; circle fill 0.4; move; circle fill 0.9;\fR"
-.PP
-GNU \fBgpic\fP makes some additional guarantees.  A fill value greater
-than 1 can also be used: this means fill with the shade of gray that
-is currently being used for text and lines.  Normally this will be
-black, but output devices may provide a mechanism for changing this.
-The invisible attribute does not affect the filling of objects.  Any
-text associated with a filled object will be added after the object
-has been filled, so that the text will not be obscured by the filling.
-.PP
-The closed-object modifier \fBsolid\fP is equivalent to \fBfill\fP
-with the darkest fill value (DWB \fBpic\fP had this capability but
-mentioned it only in a reference section).  
-.
-.NH 2
-Colored Objects
-.PP
-As a GNU extension, three additional modifiers are available to specify
-colored objects.  \fBoutline\fP sets the color of the outline, \fBshaded\fP
-the fill color, and \fBcolor\fP sets both.  All three keywords expect a
-suffix specifying the color.  Example:
-.KS
-.PS
-box color "yellow"; arrow color "cyan"; circle shaded "green" outline "black";
-.PE
-.CE "6: \fBbox color ""yellow""; arrow color ""cyan""; \
-circle shaded ""green"" outline ""black"";\fR"
-.PP
-Alternative spellings are \fBcolour\fP, \fBcolored\fP, \fBcoloured\fP,
-and \fBoutlined\fP.
-.PP
-Currently, color support is not available in \*[tx] mode.  Predefined color
-names for \fIgroff\/\fP(1) are in the device macro files, for example
-\f(CWps.tmac\fP; additional colors can be defined with the \fB.defcolor\fP
-request (see the manual page of GNU \fItroff\/\fP(1) for more details).
-.PP
-\fBpic\fP assumes that at the beginning of a picture both glyph and fill
-color are set to the default value.
-.
-.
-.NH 1
-More About Text Placement
-.PP
-By default, text is centered at the geometric center of the object it is
-associated with.  The modifier \fBljust\fP causes the left end to be
-at the specified point (which means that the text lies to the right of
-the specified place!), the modifier \fBrjust\fP puts the right end at
-the place.  The modifiers \fBabove\fP and \fBbelow\fP center the text
-one half line space in the given direction.
-.PP
-Text attributes can be combined:
-.KS
-.PS
-[line up "ljust text" ljust;] 
-move 1.5;
-[line up "rjust text" rjust;] 
-move;
-[arrow 1 "ljust above" ljust above;]
-move;
-[arrow 1 "rjust below" rjust below;]
-.PE
-.CE "1: Text attributes"
-.PP
-What actually happens is that \fIn\fP text strings are centered in a box
-that is \fBtextwid\fP wide by \fBtextht\fP high.  Both these variables
-are initially zero (that is \fBpic\fR's way of not making assumptions
-about \fI[tg]roff\/\fP(1)'s default point size).
-.PP
-In GNU \fBgpic\fR, objects can have an
-.B aligned
-attribute.
-This will only work when the postprocessor is
-\fBgrops\fP.
-Any text associated with an object having the
-.B aligned
-attribute will be rotated about the center of the object
-so that it is aligned in the direction from the start point
-to the end point of the object.
-Note that this attribute will have no effect for objects whose start and
-end points are coincident.
-.
-.
-.NH 1
-More About Direction Changes
-.PP
-We've already seen how to change the direction in which objects are
-composed from rightwards to downwards.  Here are some more
-illustrative examples:

-	"\fBup; box; arrow; circle; arrow; ellipse;\fP"
-]
-.PE
-.CE "2: Effects of different motion directions (up and down)"
-.PP
-Something that may appear surprising happens if you change directions 
-in the obvious way:
-.KS
-.PS
-box; arrow; circle; down; arrow; ellipse
-.PE
-.CE "3: \fBbox; arrow; circle; down; arrow; ellipse\fP"
-.LP
-You might have expected that program to yield this:
-.KS
-.PS
-box; arrow; circle; move to last circle .s; down; arrow; ellipse
-.PE
-.CE "4: More intuitive?"
-.LP
-But, in fact, to get Figure \*[SN]3 you have to do this:
-.KS
-.DS
-.CW
-\&.PS
-box;
-arrow;
-circle;
-move to last circle .s;
-down;
-arrow;
-ellipse
-\&.PE
-.R
-.DE
-.KE
-.LP
-Why is this?  Because the exit point for the current direction is
-already set when you draw the object.  The second arrow in Figure
-\*[SN]2 dropped downwards from the circle's attachment point for an
-object to be joined to the right.
-.PP
-The meaning of the command \fBmove to last circle .s\fP should be obvious.
-In order to see how it generalizes, we'll need to go into detail on two
-important topics; locations and object names.
-.
-.
-.NH 1
-Naming Objects
-.PP
-The most natural way to name locations in \fBpic\fP is relative to
-objects.  In order to do this, you have to be able you have to be able
-to name objects.  The \fBpic\fP language has rich facilities for this
-that try to emulate the syntax of English.
-.
-.NH 2
-Naming Objects By Order Of Drawing
-.PP
-The simplest (and generally the most useful) way to name an object is
-with a \fBlast\fP clause.  It needs to be followed by an object type
-name; \fBbox\fP, \fBcircle\fP, \fBellipse\fP, \fBline\fP, \fBarrow\fP,
-\fBspline\fP, \fB""\fP, or \fB[]\fP (the last type refers to a \fIcomposite
-object\fP which we'll discuss later).  So, for example, the \fBlast
-circle\fP clause in the program attached to Figure \*[SN]3 refers to the
-last circle drawn.
-.PP
-More generally, objects of a given type are implicitly numbered
-(starting from\~1).  You can refer to (say) the third ellipse in the
-current picture with \fB3rd ellipse\fP, or to the first box as \fB1st
-box\fP, or to the fifth text string (which isn't an attribute to another
-object) as \fB5th ""\fP.
-.PP
-Objects are also numbered backwards by type from the last one.
-You can say \fB2nd last box\fP to get the second-to-last box, or
-\fB3rd last ellipse\fP to get the third-to-last ellipse.
-.PP
-In places where \fIn\/\fBth\fR is allowed, \fB`\fIexpr\/\fB'th\fR is
-also allowed.  Note that
-.B 'th
-is a single token: no space is allowed between the
-.B '
-and the \fBth\fP.
-For example,
-.IP
-.KS
-.DS
-.CW
-for i = 1 to 4 do {
-   line from `i'th box.nw to `i+1'th box.se
-}
-.DE
-.R
-.KE
-.
-.NH 2
-Naming Objects With Labels
-.PP
-You can also specify an object by referring to a label.  A label is a
-word (which must begin with a capital letter) followed by a colon;
-you declare it by placing it immediately before the object drawing command.
-For example, the program
-.KS
-.DS
-.CW
-\&.PS
-A: box "first" "object"
-move;
-B: ellipse "second" "object"
-move;
-arrow right at A .r;
-\&.PE
-.R
-.DE
-.KE
-.LP
-declares labels \fBA\fP and \fBB\fP for its first and second objects.
-Here's what that looks like:
-.KS
-.PS
-A: box "first" "object"
-move;
-B: ellipse "second" "object"
-move;
-arrow right at A .r;
-.PE
-.CE "1: Example of label use"
-The \fBat\fP statement in the fourth line uses the label \fBA\fP (the
-behavior of \fBat\fP will be explained in the next section).  We'll
-see later on that labels are most useful for referring to block composite
-objects.  
-.PP
-Labels are not constants but variables (you can view colon as a sort
-of assignment).  You can say something like \fBA: A + (1,0);\fP
-and the effect will be to reassign the label \fBA\fR to designate a
-position one inch to the right of its old value. 
-.
-.
-.NH 1
-Describing locations
-.PP
-The location of points can be described in many different ways.  All these
-forms are interchangeable as for as the \fBpic\fP language syntax is
-concerned; where you can use one, any of the others that would make 
-semantic sense are allowed.
-.PP
-The special label \fBHere\fR always refers to the current position.
-.
-.NH 2
-Absolute Coordinates
-.PP
-The simplest is absolute coordinates in inches; \fBpic\fP uses a
-Cartesian system with (0,0) at the lower left corner of the virtual
-drawing surface for each picture (that is, X increases to the right
-and Y increases upwards).  An absolute location may always be written in the
-conventional form as two comma-separated numbers surrounded by
-parentheses (and this is recommended for clarity).  In contexts where
-it creates no ambiguity, the pair of X and Y coordinates suffices
-without parentheses.
-.PP
-It is a good idea to avoid absolute coordinates, however.  They tend
-to make picture descriptions difficult to understand and modify.
-Instead, there are quite a number of ways to specify locations
-relative to \fBpic\fP objects and previous locations.
-.PP
-Another possibility of surprise is the fact that \fBpic\fP crops the
-picture to the smallest bounding box before writing it out.  For
-example, if you have a picture consisting of a small box with its lower
-left corner at (2,2) and another small box with its upper right corner
-at (5,5), the width and height of the image are both 3\~units and
-not\~5.  To get the origin at (0,0) included, simply add an invisible
-object to the picture, positioning the object's left corner at (0,0).
-.
-.NH 2
-Locations Relative to Objects
-.PP
-The symbol \fBHere\fP always refers to the position of the last object
-drawn or the destination of the last \fBmove\fP.
-.PP
-Alone and unqualified, a \fBlast circle\fP or any other way of
-specifying a closed-object or arc location refers as a position to the
-geometric center of the object.  Unqualified, the name of a line or
-spline object refers to the position of the object start.
-.PP
-Also, \fBpic\fP objects have quite a few named locations
-associated with them.  One of these is the object center, which can be
-indicated (redundantly) with the suffix \fB.center\fP (or just \fB.c\fP).
-Thus, \fBlast circle \&.center\fP is equivalent to \fBlast
-circle\fP.
-.NH 3
-Locations Relative to Closed Objects
-.PP
-Every closed object (box, circle, ellipse, or block composite) also
-has eight compass points associated with it;
-.KS
-.PS
-define dot {circle fill rad 0.02 at $1}
-
-define compass { [
-	ME: $1;
-	dot(ME.c);  "\fB .c\fP"  at ME .c ljust;

-	dot(ME.se); "\fB .se\fP" at ME .se below
-	dot(ME.s);  "\fB.s\fP"   at ME .s below
-	dot(ME.sw); "\fB.sw \fP" at ME .sw below
-	dot(ME.w);  "\fB.w \fP"  at ME .w rjust
-	dot(ME.nw); "\fB.nw \fP" at ME .nw above
-] }
-compass(box wid 1.5 ht 1);
-move right from last [] .e;
-compass(circle diam 1);
-move right from last [] .e;
-compass(ellipse wid 1.5 ht 1);
-.PE
-.CE "1: Compass points"
-.LP
-these are the locations where eight compass rays from the geometric center
-would intersect the figure.  So when we say \fBlast circle .s\fP we are
-referring to the south compass point of the last circle drawn.  The
-explanation of Figure 7.3's program is now complete.
-.PP
-(In case you dislike compass points, the names \fB.top\fP,
-\&\fB.bottom\fP, \fB.left\fP and \fB.right\fP are synonyms for \fB.n\fP,
-\&\fB.s\fP, \fB.e\fP, and \fB.w\fP respectively; they can even be
-abbreviated to \fB.t\fP, \fB.b\fP, \fB.l\fP and \fB.r\fP).
-.PP
-The names \fBcenter\fP, \fBtop\fP, \fBbottom\fP, \fBleft\fP, \fBright\fP,
-\fBnorth\fP, \fBsouth\fP, \fBeast\fP, and \fBwest\fP can also be used
-(without the leading dot) in a prefix form marked by \fBof\fP; thus,
-\fBcenter of last circle\fP and \fBtop of 2nd last ellipse\fP are both
-valid object references.  Finally, the names \fBleft\fP and \fBright\fP
-can be prefixed with \fBupper\fP and \fBlower\fP which both have the
-obvious meaning.
-.PP
-Arc objects also have compass point; they are the compass points of
-the implied circle.
-.NH 3
-Locations Relative to Open Objects
-.PP
-Every open object (line, arrow, arc, or spline) has three named
-points: \fB.start\fP, \fB.center\fP (or \fB.c\fP), and \fB.end\fP.  They
-can also be used without leading dots in the \fBof\fP prefix form.
-The center of an arc is the center of its circle, but the center of
-a line, path, or spline is halfway between its endpoints.

-Ways of Composing Positions
-.PP
-Once you have two positions to work with, there are several ways to
-combine them to specify new positions.
-.NH 3
-Vector Sums and Displacements
-.PP
-Positions may be added or subtracted to yield a new position (to be
-more precise, you can only add a position and an expression pair; the
-latter must be on the right side of the addition or subtraction sign).
-The result is the conventional vector sum or difference of coordinates.
-For example, \fBlast box .ne + (0.1, 0)\fP is a valid position.  This 
-example illustrates a common use, to define a position slightly offset
-from a named one (say, for captioning purposes).
-.NH 3
-Interpolation Between Positions
-.PP
-A position may be interpolated between any two positions.  The syntax
-is `\fIfraction\fP \fBof the way between\fP \fIposition1\fP \fBand\fP
-\fIposition2\fP'.  For example, you can say \fB1/3 of the way between
-here and last ellipse .ne\fP.  The fraction may be in
-numerator/denominator form or may be an ordinary number (values are
-\fInot\fP restricted to [0,1]).  As an alternative to this verbose
-syntax, you can say `\fIfraction\fP  \fB<\,\fP\fIposition1\fP \fB,\fP
-\fIposition2\/\fP\fB>\fP'; thus, the example could also be written as
-\fB1/3 <here, last ellipse>\fP.

-\fB(\,\fP\fIp\fP\fB,\fP \fIq\fP\fB)\fP has the X coordinate of \fIp\fP

-Using Locations
-.PP
-There are four ways to use locations; \fBat\fP, \fBfrom\fP, \fBto\fP,
-and \fBwith\fP.  All three are object modifiers; that is, you use them
-as suffixes to a drawing command.
-.PP
-The \fBat\fP modifier says to draw a closed object or arc with its
-center at the following location, or to draw a line/spline/arrow
-starting at the following location.
-.PP
-The \fBto\fP modifier can be used alone to specify a move destination.
-The \fBfrom\fP modifier can be used alone in the same way as \fBat\fP.
-.PP
-The \fBfrom\fP and \fBto\fP modifiers can be used with a \fBline\fR or
-\fBarc\fR command to specify start and end points of the object.  In
-conjunction with named locations, this offers a very flexible
-mechanism for connecting objects.  For example, the following program
-.KS
-.DS
-.CW
-\&.PS
-box "from"
-move 0.75;
-ellipse "to"
-arc cw from 1/3 of the way \e
-    between last box .n and last box .ne to last ellipse .n;

-arc cw from 1/3 of the way \
-    between last box .n and last box .ne to last ellipse .n;
-.PE
-.CE "6: A tricky connection specified with English-like syntax"
-.PP
-The \fBwith\fP modifier allows you to identify a named attachment
-point of an object (or a position within the object) with another point.

-The `chop' Modifier
-.PP
-When drawing lines between circles that don't intersect them at a

-of the circle at either or both ends.  Consider the following program:
-.KS

-\&.PS
-circle "x"
-circle "y" at 1st circle - (0.4, 0.6) 
-circle "z" at 1st circle + (0.4, -0.6)

-arrow from 2nd circle to 3rd circle chop 
-arrow from 3rd circle to 1st circle chop 
-.PE
-.CE "8: The \fBchop\fR modifier"
-.LP
-Notice that the \fBchop\fR attribute moves arrowheads rather than
-stepping on them.  By default, the \fBchop\fR modifier shortens both
-ends of the line by \fBcirclerad\fR.  By suffixing it with a number
-you can change the amount of chopping.
-.PP
-If you say \fBline .\|.\|.\& chop \fIr1\fP chop \fIr2\fP\fR with \fIr1\fP
-and \fIr2\fP both numbers, you can vary the amount of chopping at both
-ends.  You can use this in combination with trigonometric functions
-to write code that will deal with more complex intersections.
-.
-.
-.NH 1
-Object Groups
-.PP
-There are two different ways to group objects in \fBpic\fP; \fIbrace
-grouping\fP and \fIblock composites\fP.
-.
-.NH 2
-Brace Grouping
-.PP
-The simpler method is simply to group a set of objects within curly
-bracket or brace characters.  On exit from this grouping, the current
-position and direction are restored to their value when the opening
-brace was encountered.
-.
-.NH 2
-Block Composites
-.PP
-A block composite object is created a series of commands enclosed by
-square brackets.  The composite can be treated for most purposes like
-a single closed object, with the size and shape of its bounding box.
-Here is an example.  The program fragment

-To refer to one of the composite's attachment points, you can say

-very important for putting together large, multi-part diagrams.
-.PP 
-Blocks are also a variable-scoping mechanism, like a \fIgroff\/\fP(1)
-environment.  All variable assignments done inside a block are undone
-at the end of it.  To get at values within a block, write a name of
-the block followed by a dot, followed by the label you
-want.  For example, we could refer the the center of the box in the
-above composite as \fBlast [] .Caption\fP or \fBA.Caption\fP.
-.PP
-This kind of reference to a label can be used in any way any other
-location can be.  For example, if we added \fB"Hi!" at A.Caption\fP

-Style Variables

-previous sections.  They're all described here.  For each variable,
-the default is given.
-.TS H

-Any of these variables can be set with a simple assignment statement.
-For example:

-.PE
-.CE "1: \fBboxht=1; boxwid=0.3; movewid=0.2; box; move; box; move; box; move; box;\fP"
-.PP
-In GNU \fBpic\fR, setting the \fBscale\fR variable re-scales all
-size-related state variables so that their values remain equivalent in
-the new units.
-.PP
-The command \fBreset\fP resets all style variables to their defaults.
-You can give it a list of variable names as arguments (optionally
-separated by commas), in which case it resets only those.
-.PP
-State variables retain their values across pictures until reset.
-.

-.NH 1
-Expressions, Variables, and Assignment
-.PP
-A number is a valid expression, of course (all numbers are stored
-internally as floating-point).  Decimal-point notation is acceptable;
-in GNU \fBgpic\fR, scientific notation in C's `e' format (like
-\f(CW5e-2\fP) is accepted.
-.PP
-Anywhere a number is expected, the language will also accept a
-variable.  Variables may be the built-in style variable described in
-the last section, or new variables created by assignment.
-.PP
-DWB \fBpic\fP supports only the ordinary assignment via \fB=\fP, which
-defines the variable (on the left side of the equal sign) in the current
-block if it is not already defined there, and then changes the value (on
-the right side) in the current block.  The variable is not visible outside
-of the block.  This is similar to the C\~programming language where a
-variable within a block shadows a variable with the same name outside of
-the block.
-.PP
-GNU \fBgpic\fP supports an alternate form of assignment using \fB:=\fP.
-The variable must already be defined, and the value will be assigned to
-that variable without creating a variable local to the current block.
-For example, this
-.KS
-.DS
-.CW
-x=5
-y=5
-[
-  x:=3
-  y=3
-]
-print x " " y
-.DE
-.KE
-.LP
-prints \fB3 5\fP.
-.PP
-You can use the height, width, radius, and x and y coordinates of any
-object or corner in expressions.  If \fBA\fP is an object label or name,
-all the following are valid:
-.KS
-.DS
-.CW
-A.x                  # x coordinate of the center of A
-A.ne.y               # y coordinate of the northeast corner of A
-A.wid                # the width of A
-A.ht                 # and its height
-2nd last circle.rad  # the radius of the 2nd last circle
-.R
-.DE
-.KE
-.LP
-Note the second expression, showing how to extract a corner coordinate.
-.PP
-Basic arithmetic resembling those of C operators are available; \fB+\fP,
-\fB*\fP, \fB-\fP, \fB/\fP, and \fB%\fP.  So is \fB^\fP for exponentiation.
-Grouping is permitted in the usual way using parentheses.  GNU \fBgpic\fP
-allows logical operators to appear in expressions; \fB!\&\fP (logical
-negation, not factorial), \fB&&\fP, \fB|\||\fP, \fB==\fP, \fB!=\fP,
-\fB>=\fP, \fB<=\fP, \fB<\fP, \fB>\fP.
-.PP
-Various built-in functions are supported: \fBsin(\fIx\fB)\fR,
-\fBcos(\fIx\fB)\fR, \fBlog(\fIx\fB)\fR, \fBexp(\fIx\fB)\fR,
-\fBsqrt(\fIx\fB)\fR, \fBmax(\fIx\fB,\fIy\fB)\fR,
-\fBatan2(\fIx\fB,\fIy\fB)\fR, \fBmin(\fIx\fB,\fIy\fB)\fR,
-\fBint(\fIx\fB)\fR, \fBrand()\fP, and \fBsrand()\fP.
-Both \fBexp\fP and \fBlog\fP are
-base\~10; \fBint\fP does integer truncation; \fBrand()\fP returns a
-random number in [0-1), and \fBsrand()\fP sets the seed for 
-a new sequence of pseudo-random numbers to be returned by \fBrand()\fP
-(\fBsrand()\fP is a GNU extension).
-.PP
-GNU \fBgpic\fP also documents a one-argument form or rand,
-\fBrand(\fIx\fB)\fR, which returns a random number between 1 and
-\fIx\fP, but this is deprecated and may be removed in a future
-version.
-.PP
-The function \fBsprintf()\fP behaves like a C \fIsprintf\/\fP(3)
-function that only takes %, %e, %f, and %g format strings.
-.
-.
-.NH 1
-Macros
-.PP
-You can define macros in \fBpic\fP.  This is useful for diagrams with
-repetitive parts.  In conjunction with the scope rules for block
-composites, it effectively gives you the ability to write functions.
-.PP
-The syntax is
-.DS
-.CW
-\fBdefine\fP \fIname\fP \fB{\fP \fIreplacement text \fB}\fP
-.R
-.DE
-.LP
-This defines \fIname\fR as a macro to be replaced by the replacement

-.DS

-\fIname\fB(\fIarg1, arg2, \|.\|.\|.\& argn\fB)\fR
-.R

-The arguments (if any) will be substituted for tokens \fB$1\fP, \fB$2\fP

-In general, \fBpic\fP is a free-format, token-oriented language that
-ignores whitespace outside strings.  But certain lines and contructs
-are specially interpreted at the lexical level:
-.PP
-A comment begins with \fB#\fP and continues to \fB\en\fP (comments may
-also follow text in a line).  A line beginning with a period or
-backslash may be interpreted as text to be passed through to the
-post-processor, depending on command-line options.  An end-of-line
-backslash is interpreted as a request to continue the line; the
-backslash and following newline are ignored.
-.PP
-.RS
-Here are the grammar terminals:
-.IP \s[-1]INT\s[0]
-A positive integer.
-.IP \s[-1]NUMBER\s[0]
-A floating point numeric constant.  May contain a decimal point or be
-expressed in scientific notation in the style of \fIprintf\/\fP(3)'s %e
-escape.  A trailing `i' or `I' (indicating the unit `inch') is ignored.
-.IP \s[-1]TEXT\s[0]
-A string enclosed in double quotes.  A double quote within \s[-1]TEXT\s[0]
-must be preceded by a backslash.  Instead of \s[-1]TEXT\s[0] you can use
-.DS
-.CW
-sprintf ( TEXT [, <expr> ...] )
-.R
-.DE
-.IP
-except after the `until' and `last' keywords, and after all ordinal
-keywords (`th' and friends).
-.IP \s[-1]VARIABLE\s[0]
-A string starting with a character from the set [a-z], optionally
-followed by one or more characters of the set [a-zA-Z0-9_].
-(Values of variables are preserved across pictures.)
-.IP \s[-1]LABEL\s[0]
-A string starting with a character from the set [A-Z], optionally
-followed by one or more characters of the set [a-zA-Z0-9_].
-.IP \s[-1]COMMAND-LINE\s[0]
-A line starting with a command character (`.' in groff mode, `\e' in

-Tokens not enclosed in \[la]\|\[ra] are literals, except:

-\fB\en\fP is a newline.
-.IP 2.
-Three dots is a suffix meaning `replace with 0 or more repetitions
-of the preceding element(s).
-.IP 3.
-An enclosure in square brackets has its usual meaning of `this clause is
-optional'.
-.IP 4.
-Square-bracket-enclosed portions within tokens are optional.  Thus,
-`h\^[eigh]\^t' matches either `height' or `ht'.

-As Kernighan notes, \[lq]since barbarisms like \fB1th\fP and \fB3th\fP are

-an expression, as opposed to a numeric literal) is not documented in DWB's
-\fIpic\/\fR(1).
-.PP
-The \[la]\,\fIxxx\/\fP-of\|\[ra] rule is special: The lexical parser checks whether

-Both \fBexp\fP and \fBlog\fP are base 10; \fBint\fP does integer

-.DS

-History and Acknowledgements
-.PP
-Original \fBpic\fP was written to go with Joseph Ossanna's original
-\fItroff\/\fP(1) by Brian Kernighan, and later re-written by Kernighan
-with substantial enhancements (apparently as part of the evolution of
-\fItroff\/\fP(1) into \fIditroff\/\fP(1) to generate
-device-independent output).
-.PP
-The language had been inspired by some earlier graphics languages
-including \fBideal\fP and \fBgrap\fP.  Kernighan credits Chris van Wyk
-(the designer of \fBideal\fP) with many of the ideas that went into
-\fBpic\fP.

-The \fBpic\fP language was originally described by Brian Kernighan in
-Bell Labs Computing Science Technical Report #116 (you can obtain a
-PostScript copy of the revised version, [1], by sending a mail message to
-\fInetlib@research.att.com\fP with a body of `send 116 from

-% To process a Texinfo manual with TeX, it's most reliable to use the
-% texi2dvi shell script that comes with the distribution.  For a simple
-% manual foo.texi, however, you can get away with this:
-%   tex foo.texi
-%   texindex foo.??
-%   tex foo.texi
-%   tex foo.texi
-%   dvips foo.dvi -o  # or whatever; this makes foo.ps.
-% The extra TeX runs get the cross-reference information correct.
-% Sometimes one run after texindex suffices, and sometimes you need more
-% than two; texi2dvi does it as many times as necessary.

-% @multitable macros
-% Amy Hendrickson, 8/18/94, 3/6/96
-%
-% @multitable ... @end multitable will make as many columns as desired.
-% Contents of each column will wrap at width given in preamble.  Width
-% can be specified either with sample text given in a template line,
-% or in percent of \hsize, the current width of text on page.
-
-% Table can continue over pages but will only break between lines.
-
-% To make preamble:
-%
-% Either define widths of columns in terms of percent of \hsize:
-%   @multitable @columnfractions .25 .3 .45
-%   @item ...
-%
-%   Numbers following @columnfractions are the percent of the total
-%   current hsize to be used for each column. You may use as many
-%   columns as desired.
-
-
-% Or use a template:
-%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-%   @item ...
-%   using the widest term desired in each column.
-
-% Each new table line starts with @item, each subsequent new column
-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab do not need to be on their own lines, but it will not hurt
-% if they are.
-
-% Sample multitable:
-
-%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-%   @item first col stuff @tab second col stuff @tab third col
-%   @item
-%   first col stuff
-%   @tab
-%   second col stuff
-%   @tab
-%   third col
-%   @item first col stuff @tab second col stuff
-%   @tab Many paragraphs of text may be used in any column.
-%
-%         They will wrap at the width determined by the template.
-%   @item@tab@tab This will be in third column.
-%   @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.
-% @multitablelinespace is space to leave between table items, baseline
-%                                                            to baseline.

-README
-
-This is the GNU groff document formatting system.
-The version number is given in the file VERSION.
-
-Included in this release are implementations of troff, pic, eqn, tbl,
-grn, refer, \-man, \-mdoc, and \-ms macros, and drivers for PostScript,
-TeX dvi format, HP LaserJet\~4 printers, Canon CAPSL printers, HTML format
-(beta status), and typewriter-like devices.
-Also included is a modified version of the Berkeley \-me macros, an enhanced
-version of the X11 xditview previewer, and an implementation of the \-mm
-macros contributed by
-.MTO jh@\:axis.se "J\[:o]rgen H\[:a]gg" .
-
-See the file INSTALL for installation instructions.
-You will require a C++ compiler.
-
-The file NEWS describes recent user-visible changes to groff.
-
-Groff is free software.
-See the file COPYING for copying permission.
-
-The file PROBLEMS describes various problems that have been encountered in
-compiling, installing, and running groff.
-
-The most recent released version of groff is always available by
-.URL "ftp://\:ftp.gnu.org/\:gnu/\:groff" "anonymous ftp" .
-
-The current development version of groff is available from a
-.URL "http://\:savannah.gnu.org/\:cvs/\:?group=groff" "CVS repository" .
-You can access it by first selecting a parent directory in
-which to create a working copy (call it, say, ~/cvswork), and then
-executing the commands
-
-.in 2m
-.nf
-.ft C
-cd ~/cvswork
-CVS_RSH=ssh; export CVS_RSH
-cvs -d:ext:anoncvs@savannah.gnu.org/cvsroot/groff -z5 co groff
-.ft P
-.fi
-.in
-
-(Note that you need an SSH client for security reasons.)
-
-This will create a subdirectory, ~/cvswork/groff, with a `checked out'
-copy of the CVS repository.
-An update of this working copy may be
-achieved, at any later time by invoking the commands
-
-.in 2m
-.nf
-.ft C
-cd ~/cvswork/groff
-CVS_RSH=ssh cvs -z5 update -dP
-.ft P
-.fi
-.in
-
-Please read the CVS info pages for further details.
-
-Finally, it is possible to access the CVS with a
-.URL http://\:savannah.gnu.org/\:cvs/\:?group=groff "web browser" .
-
-Alternatively, you can download snapshots (which are updated twice a day).
-The complete groff source as a single file is available
-.URL http://\:groff.ffii.org/\:groff/\:devel/\:groff-current.tar.gz here .
-
-A diff file relative to groff-\[la]version\[ra], the latest official groff
-release is available at
-
-.in 2m
-.ft C
-http://groff.ffii.org/groff/devel/groff-\[la]version\[ra]-current.diff.gz
-.ft P
-.in
-
-Assuming that groff-\[la]version\[ra].tar.gz and
-groff-\[la]version\[ra]-current.diff.gz are in the same directory, do the
-following to apply the diff file:
-
-.in 2m
-.nf
-.ft C
-tar xzvf groff-\[la]version\[ra].tar.gz
-cd groff-\[la]version\[ra]
-gunzip -c ../groff-\[la]version\[ra]-current.diff.gz | patch -p1
-.ft P
-.fi
-.in
-
-Depending on your requirements, you may need at least some of the
-following tools to build groff directly from its source:
-
-.in 2m
-.nf
-ghostscript
-the psutils package
-the netpbm package
-texinfo 4.8
-bison \[>=] 1.875b or byacc
-.fi
-.in
-
-Note that texinfo and bison or byacc are required only for building from
-CVS sources (either a checked out working copy, or a daily snapshot).
-They are not required for building from a stable release tarball.
-Also note that the version numbers stated are the minimum supported.
-No version of texinfo < 4.8 will work, and the original release of bison
-1.875 is known not to work; you \fImay\fP find that bison releases < 1.875
-will work, but in case of difficulty, please update to a later version
-\fIbefore\fP posting a bug report.
-
-For \fIall\fP sources, you need ghostscript for creation of either PDF or
-HTML output; the netpbm and psutils packages are required only for HTML
-output.
-If you don't intend to produce output in either of these formats, then
-these packages are unnecessary.
-
-Please report bugs using the form in the file BUG-REPORT; the idea of this
-is to make sure that FSF has all the information it needs to fix the bug.
-At the very least, read the BUG-REPORT form and make sure that you supply
-all the information that it asks for.
-Even if you are not sure that something is a bug, report it using
-BUG-REPORT: this will enable us to determine whether it really is a bug or
-not.

-and `VPS' register larger than or equal to 1000 is always divided by 1000.
-For example, `.nr\~PS\~10250' sets the document's font size to 10.25 points.
-
-.LI
-The `Ds' and `De' macros provided in ms since groff version 1.19 have
-been removed; the equivalent `DS' and `DE' macros should be used instead.
-X11 documents which actually use `Ds' and `De' always load a
-specific macro file from the X11 distribution (`macros.t') which
-provides proper definitions for the two macros.
-
-.LI
-The following registers have been added for improving layout control:
-
-.IP PORPHANS
-Defines number of lines following `LP', `PP', `QP', `IP' or `XP' which
-must be kept together, before any automatic page break.
-
-.IP HORPHANS
-Sets number of lines of following paragraph which must be kept with a
-heading, defined by `NH' or `SH', before any automatic page break.
-
-.IP GROWPS
-Sets the first level of heading (set with `NH') which will keep the
-same point size as body text.
-
-.IP PSINCR
-Sets the point size increment for each level of heading (set with
-`NH'), below the threshold level set by `GROWPS'; e.g., if
-\en[PS]\~=\~10, \en[GROWPS]\~=\~3 and \en[PSINCR]\~=\~2.0p, then `.NH\~1'
-will produce 14pt headings, `.NH\~2' will produce 12pt, and all other levels
-will remain at 10pt (because \en[PS]\~=\~10).
-
-.LI
-The `SH' macro now accepts a numeric argument, to make heading size
-match that of `NH' with same argument value when the `GROWPS'/`PSINCR'
-feature is enabled.
-.ULE

-Please refer to the documentation of the ms package for other, minor
-improvements.

-added.
-Example use:

-
-Note that some output devices don't support all glyphs of this encoding.

-If the `return' request is called with an argument, it exits twice,
-namely the current macro and the macro one level higher.
-This is used to define a wrapper macro for `return' in trace.tmac.
-
-.LI
-For completeness, two new requests have been added: `dei1' and `ami1'.
-They are equivalent to `dei' and `ami', respectively, but the macros
-are executed with compatibility mode off (similar to `de1' and `am1').
-

-New command line option `\-I' to specify a directory for files (both
-those on the command line and those named in `psbb' requests).
-This is also handled by the groff wrapper program.

-     http://partners.adobe.com/asn/tech/type/unicodegn.jsp
-is used to construct glyph names based on Unicode character codes.
-The existing groff glyph names are frozen; no glyph names which can't be
-constructed algorithmically will be added in the future.
-
-The \e[...] escape sequence has been extended to specify multiple glyph
-components.
-Example:
-

-Some groff glyphs which are useful as composites map to `wrong' Unicode
-code points.
-For example, `ho' maps to U+02DB which is a spacing ogonek, whereas a
-non-spacing ogonek U+0328 is needed for composite glyphs.
-The new request
-
-.in 2m
-.ft C
-\&.composite from to
-.ft R
-.in
-
-will change the mapping while a composite glyph name is constructed.
-To make \e[A\~ho] yield the expected result,
-
-.in 2m
-.ft C
-\&.composite ho u0328
-.ft R
-.in
-
-is needed.
-[The new file `composite.tmac' loaded at start-up already
-contains proper calls to `.composite'.]
-
-Please refer to the info pages of groff and to the groff_char man page

-A new request `fschar' has been added to define font-specific fallback
-characters.
-They are searched after the list of fonts declared with the
-`fspecial' request but before the list of fonts declared with `special'.
-
-.LI
-Fallback characters defined with `fschar' can be removed with the
-new `rfschar' request.

-They are searched after the list of fonts declared with the
-`special' request but before the already mounted special fonts.
-
-.LI
-In groff versions 1.18 and 1.18.1, \eD'f\~...'\& didn't move the current
-point horizontally.
-Despite of being silly, this change has been reverted for backwards
-compatibility.
-Consequently, the intermediate output command `Df' also moves the 
-position horizontally again.
-
-\eD'f\~...'\& is deprecated since it depends on the horizontal resolution
-of the output device (given with the `hor' parameter in the DESC file).
-Use the new \eD'Fg\~...'\& escape instead.
-
-.LI
-For orthogonality, new \eD subcommands to change the fill color are
-available:

-The values set with \eH and \eS are now available in number registers
-\en[.height] and \en[.slant], respectively.

-The `.pe' number register isn't new but hasn't been documented before.
-It is set to\~1 during a page ejection caused by the `bp' request.
-

-The new glyph symbol `tno' is a textual variant of `no'.
-
-.LI
-The new glyph symbol `+e' represents U+03F5, GREEK LUNATE EPSILON SYMBOL.
-(Well, it is not really new since it has been previously supported by
-grolj4.)
-The mapping for both the dvi and lj4 symbol font has been

-(provided the font file created by afmtodit has proper entries).
-grops constructs additional encoding vectors on the fly if necessary.

-The paper size is now emitted via the %%DocumentMedia and PageSize
-mechanisms so that it is no longer required to tell `gv' or `ps2pdf'

-The `broken' flag value\~16 omits this feature
-(the used PostScript command `setpagedevice' is a LanguageLevel\~2

-The non-slanted PostScript font definition files have been regenerated to
-include left and right italic correction values.
-Applying those to a glyph (this is, prepending the glyph with `\e,' and
-appending `\e/' to the glyph) sets the glyph width to the real value given
-by the horizontal bounding box values.
-Without those escapes, the advance width for the particular glyph is used
-(which can differ considerably).
-
-Most users will neither need this feature nor notice a difference in
-existing documents (provided \e, and \e/ is used as advertised, namely for

-Troff
-
-.ULS
-.LI
-Color support has been added to troff and pic (and to the device drivers
-grops, grodvi, grotty, and grohtml -- other preprocessors and drivers will
-follow).
-A new function `defcolor' defines colors; the escape sequence `\em' sets the
-drawing color, the escape sequence `\eM' specifies the background color for
-closed objects created with \eD'.\|.\|.' commands.
-`\em[]' and `\eM[]' switch back to the previous color.
-`\em' and `\eM' correspond to the new troff output command sets starting
-with `m' and `DF'.
-The device-specific default color is called `default' and can't be
-redefined.
-
-Use the `color' request to toggle the usage of colors (default is on); the
-read-only register `.color' is\~0 if colors are not active, and non-zero
-otherwise.
-
-The old `Df' output command is mapped onto `DFg'; all color output
-commands don't change the current font position (consequently, `Df'
-doesn't either).
-
-Outputting color can be disabled in troff and groff with the option\~\-c
-(it is always disabled in compatibility mode).
-See the section on grotty for the
-.ie '\*[.T]'html' \
-.  URL #GROFF_NO_SGR GROFF_NO_SGR
-.el \
-. nop GROFF_NO_SGR
-environment variable also.
-
-For defining color components as fractions between 0 and\~1, a new scaling
-indicator `f' has been defined: 1f\~=\~65536u.
-For testing whether a color is defined (with .if and .ie), a new
-conditional operator `m' is available.
-
-More details can be found in the groff_diff.7 manual page and in
-groff.texinfo.
-
-.LI
-Similar to \em and \eM, \ef[] switches back to the previous font.
-\efP (and \ef[P]) is still valid for backwards compatibility.
-
-.LI
-The new escape \eF is the same as `.fam'; \eF[] switches back to previous
-family -- \eF[P] selects family `P'.
-
-.LI
-Two new glyph symbols are available: `eu' is the official Euro symbol;
-`Eu' is a font-specific glyph variant.
-
-.LI
-The new glyph symbols `t+\-', `tdi', and `tmu' are textual variants of
-`+\-', `di', and `mu', respectively.
-
-.LI
-Latin-1 character 181 (PS name `mu', Unicode name U+00B5 MICRO SIGN) has
-got the troff glyph name `mc'.
-
-.LI
-\-Tutf8 is now available on EBCDIC hosts.
-
-.LI
-Strings can take arguments, using this syntax: \e*[foo\~arg1\~arg2\~.\|.\|.].
-Example:
-
-.in 2m
-.nf
-.ft C
-\&.ds xxx This is a \e\e$1 test.
-\e*[xxx nice]
-.ft P
-.fi
-.in
-
-.LI
-It is now possible to have whitespace between the first and second dot (or
-the name of the ending macro) to end a macro definition.
-Example:
-
-.in 2m
-.nf
-.ft C
-\&.de !
-\&..
-\&.
-\&.de foo
-\&.  nop Hello, I'm `foo'.
-\&.  nop I will now define `bar'.
-\&.  de bar !
-\&.    nop Hello, I'm `bar'.
-\&.  !
-\&..
-.ft P
-.fi
-.in
-
-.LI
-`.fn' is a new string-valued register which returns the (internal) real
-font name; styles and families are properly concatenated.
-
-.LI
-Three new read/write registers `seconds', `minutes', and `hours' contain
-the current time, set at start-up of troff.
-Use the `af' request to control their output format.
-
-.LI
-The new request `fchar' can be used to provide fallback characters.
-It has the same syntax as the `char' request; the only difference is that
-a character defined with `.char' hides the glyph with the same name in the
-current font, whereas a character defined with `.fchar' is checked only if
-the particular glyph isn't found in the current font.
-This test happens before checking special fonts.
-
-.LI
-In analogy to the `tmc' request, `.writec' is the same as `.write' but
-doesn't emit a final newline.
-
-.LI
-The new request `itc' is a variant of `.it' for which a line interrupted
-with \ec counts as one input line.
-
-.LI
-Two new requests `ds1' and `as1' which are similar to `ds' and `as' but
-with compatibility mode disabled during expansion of strings defined by
-them.
-
-.LI
-The syntax of the `substring' request has been changed:
-The first character in a string now has index\~0, the last character
-has index\~\-1.
-Note that this is an incompatible change.
-
-.LI
-To emit strings directly to the intermediate output, a new `output'
-request has been added; it is similar to `\e!' used at the top level.
-
-.LI
-`.hpf' has been extended.
-It can now handle most TeX hyphenation pattern files without
-modification.
-To do that, the commands \epatterns, \ehyphenation, and \eendinput are
-recognized.
-Please refer to groff_diff.7 for more information.
-
-.LI
-`hpfcode' is a new request to provide an input encoding mapping for the
-`hpf' request.
-
-.LI
-The new request `hpfa' appends hyphenation patterns (`hpf' replaces
-already existing patterns).
-
-.LI
-A new request `ami' (append macro indirect) has been added.
-The first and second parameter of `ami' are taken from string registers
-rather than directly; this very special request is needed to make
-`trace.tmac' independent from the escape character (which might even
-be disabled).
-
-.LI
-The new request `sizes' is similar to the `sizes' command in DESC files.
-It expects the same syntax; the data must be on a single line, and the
-final `0' can be omitted.
-
-.LI
-`trin' (translate input) is a new request which is similar to `tr' with
-the exception that the `asciify' request will use the character code (if
-any) before the character translation.
-Example:
-
-.in 2m
-.nf
-.ft C
-\&.trin ax
-\&.di xxx
-a
-\&.br
-\&.di
-\&.xxx
-\&.trin aa
-\&.asciify xxx
-\&.xxx
-.ft P
-.fi
-.in
-
-The result is `x\~a'.  Using `tr', the result would be `x\~x'.
-
-.LI
-The request `pvs' isn't new, but hasn't been documented before.
-It adds vertical space after a line has been output.
-This makes it an alternative to the `ls' request to produce
-double-spaced documents.
-The read-only register `.pvs' holds the current amount of the
-post-vertical line space.
-
-.LI
-For compatibility with plan 9's troff, multiple `pi' requests are
-supported:
-
-.in 2m
-.nf
-.ft C
-\&.pi foo
-\&.pi bar
-.ft P
-.fi
-.in
-
-is now equivalent to
-
-.in 2m
-.ft C
-\&.pi foo | bar
-.ft P
-.in
-
-.LI
-A new escape sequence `\eO' is available to disable and enable glyph
-output.
-Please see groff_diff.man and groff.texinfo for more details.
-
-.LI
-The escapes `\e%', `\e&', `\e)', and `\e:' no longer cause an error in \eX;
-they are ignored now.
-Additionally `\e\ ' and `\e~' are converted to single space characters.
-
-.LI
-The default tab distance in nroff mode is now 0.8i to be compatible
-with UNIX troff.
-
-.LI
-Using the latin-1 input character 0xAD (soft hyphen) for the `shc'
-request was a bad idea.
-Instead, it is now translated to `\e%', and the default hyphenation
-character is again \e[hy].
-Note that the glyph \e[shc] is not useful for typographic purposes;
-it only exists to have glyph names for all latin-1 characters.

-.LI
-.MTO df191@\:ncf.ca "Peter Schaffter"
-has contributed a new major macro package called `mom', mainly for
-non-scientific writers, which takes care of many typographic issues.
-It comes with a complete reference (in HTML format) and some examples.
-`mom' has been designed to format documents for PostScript output only.

-.LI
-Two macros `AT' (AT&T) and `UC' (Univ. of California) have been added to
-the man macros for compatibility with older BSD releases.
-
-.LI
-Both the man and mdoc macro packages now use the LL and LT registers for
-setting the line and title length, respectively (similar to those
-registers in the ms macro package).
-If not set on the command line or in a macro file loaded before the macro
-package itself, they default to 78n in nroff mode and 6.5i in troff mode.

-The `\-xwidth' specifier in the mdoc macro package has been removed.
-Its functionality is now integrated directly into `\-width'.
-Similarly, `\-column' has been extended to has this functionality also.

-By default, font sizes are now available in the range 5\-10000pt, similar
-to PS fonts.
-If you want the old behaviour (i.e., font sizes at discrete values only),
-insert the following at the start of your document:
-
-.in 2m
-.nf
-.ft C
-\&.if '\e*[.T]'dvi' \e
-\&.  sizes 500 600 700 800 900 1000 1095 1200 1400 1440 1600 \e
-\&         1728 1800 2000 2074 2200 2400 2488 2800 3600
-.ft P
-.fi
-.in
-
-.LI
-A new font file HBI (using cmssbxo10; this is slanted sans serif bold
-extended) has been added.
-
-.LI
-Two font families are now available: `T' and `H'.
-
-.LI
-EC and TC fonts have been integrated.
-Use `\-mec' (calling the file ec.tmac) to switch to them.
-Those fonts give a much better coverage of the symbols defined by groff
-than the CM fonts.
-
-Note that ec.tmac must be called before any language-specific files; it
-doesn't take care of hcode values.
-
-.LI
-Color support has been added.
-For drawing commands, colors are translated to gray values currently.
-.ULE

-.TAG grotty
-.SH 2
-Grotty
-
-.ULS
-.LI
-Color support has been added, using the SGR (ISO\~6429, sometimes called
-ANSI color) escape sequences.
-
-.LI
-SGR escape sequences are now used by default for underlining and bold
-printing also, no longer using the backspace character trick.
-To revert to the old behaviour, use the `\-c' switch.
-
-Note that you have to use the `\-R' option of `less' to make SGR escapes
-display correctly.
-On the other hand, terminal programs and consoles like `xterm' which
-support SGR sequences natively can directly display the output of grotty.
-Consequently, the options `\-b', `\-B', `\-u', and `\-U' work only in
-combination with `\-c' and are ignored silently otherwise.
-
-For the `man' program, it may be necessary to add the `\-R' option of
-`less' to the $PAGER environment variable; alternatively, you can use
-`man's `\-P' option (or adapt its configuration file accordingly).
-See man(1) for more details.
-
-.TAG GROFF_NO_SGR
-.LI
-If the environment variable GROFF_NO_SGR is set, SGR output is disabled,
-reverting to the old behaviour.
-
-.LI
-A new special \eX'tty:\~sgr\~n' has been added; if n is non-zero or missing,
-enable SGR output (the default).
-
-.LI
-If the new option `\-i' is used (only in SGR mode), grotty sends escape
-sequences to set the italic font attribute instead of the underline
-attribute for italic fonts.
-Note that many terminals don't have support for this (including xterm).
-.ULE

-.SH 2
-grohtml
-
-.ULS
-.LI
-Color support for glyphs has been added.
-
-.LI
-New option `\-h' to select the style of headings in HTML output.
-
-.LI
-New option `\-b' to set the background colour to white.
-
-.LI
-New options `\-a' and `\-g' to control the number of bits for anti-aliasing
-used for text and graphics, respectively.
-Default value is\~4; 0\~means no anti-aliasing.
-
-.LI
-groff character/glyph entities now map onto HTML\~4 character entities.
-.ULE
-.
-.
-.SH 2
-Grolbp
-
-.ULS
-.LI
-Valid paper sizes are now specified as with the new `papersize' keyword
-in the DESC file.
-Specifically, the old custom paper type format `custAAAxBBB' is no longer
-supported.
-.ULE
-.
-.
-.SH 2
-Miscellaneous
-
-.ULS
-.LI
-A new manual page `ditroff.7' is available.
-
-.LI
-The groff texinfo manual will now be installed, together with a bunch
-of examples.
-
-.LI
-A new keyword `papersize' has been added to the DESC file format.
-Its argument is either
-
-.ULS
-.LI
-a predefined paper format (e.g. `A4' or `letter')
-
-.LI
-a file name pointing to a file which must contain a paper size
-specification in its first line (e.g. `/etc/papersize')
-
-.LI
-a custom paper size definition like `35c,4i'
-.ULE
-
-See groff_font(5) for more details.
-This keyword only affects the physical dimensions of the output medium;
-grops, grolj4, and grolbp use it currently.
-troff completely ignores it.

-Note that all \[charXXX] entity names have been removed from the font files.
-They don't make sense for Unicode.
-
-The following entity from the original troff manual (by Ossanna and
-Kernighan) is unmapped:
-
-  bs    shaded solid ball (Bell System logo, AT&T logo)
-
-Character 0x002D has not been given a name because its Unicode name
-HYPHEN-MINUS is so ambiguous that it is unusable for serious typographic
-use.
-
-\[wp] has been mapped to 0x2118, because according to Unicode 4.1's
-NamesList.txt, U+2118 SCRIPT CAPITAL P is really a Weierstrass `p',
-neither SCRIPT not CAPITAL.
-
-The following line could be added; \[space] is known to devps but is not
-documented and not known to devdvi (actually, there is no space glyph within
-the TeX system).
-
-  space   24   0   0x0020
-
-devps maps \[a~] and `~' to `asciitilde', which is equivalent to 0x02DC, but
-this glyph is just too small.  We map them to 0x007E instead.
-
-devps maps \[a^] and `^' to `circumflex', which is equivalent to 0x02C6, but
-this glyph is just too small.  We map them to 0x005E instead.
-
-devps maps \[*U] to `Upsilon1', which is equivalent to 0x03D2.  We map it to
-0x03A5 instead.
-
-devps maps \[*W] to `Omega', which is equivalent to either 0x2126 or 0x03A9.
-We map it to 0x03A9.
-
-devps maps \[*D] to `Delta', which is equivalent to either 0x2206 or 0x0394.
-We map it to 0x0394.
-
-
-Adding Unicode characters
--------------------------
-
-Assume you want to use a Unicode character not provided in the list, say
-U+20AC. You need to do two things:
-
-- Add a line
-
-    u20AC   24   0   0x20AC
-
-  (the second column is computed as 24 * wcwidth(0x20AC)) to the file
-  R.proto, or, when groff is already installed, to the four fonts files in
-  $(prefix)/share/groff/<version>/font/devutf8/.
-
-- In your source file, use the notation \[u20AC] to access it.

-.TH DITROFF @MAN7EXT@ "@MDATE@" "Groff Version @VERSION@"
-.SH NAME
-ditroff \- classical device independent roff
-.
-.
-.\" --------------------------------------------------------------------
-.SH DESCRIPTION
-.\" --------------------------------------------------------------------
-.
-The name
-.I ditroff
-once marked a development level of the
-.I troff
-text processing system.
-.
-In actual
-.BR roff (@MAN7EXT@)
-systems, the name
-.I troff
-is used as a synonym for
-.IR ditroff .
-.
-.P
-The first roff system was written by Joe Osanna around 1973.
-.
-It supported only two output devices, the
-.B nroff
-program produced text oriented tty output, while the
-.B troff
-program generated graphical output for exactly one output device, the Wang
-.I Graphic Systems CAT
-typesetter.
-.
-.P
-In 1979, Brian Kernighan rewrote troff to support more devices by
-creating an intermediate output format for troff that can be fed into
-postprocessor programs which actually do the printout on the device.
-.
-Kernighan's version marks what is known as 
-.I classical troff
-today.
-.
-In order to distinguish it from Osanna's original mono-device version,
-it was called
-.I ditroff
-(\c
-.IR d\/ evice\~ i\/ ndependent\~ troff\/\c
-)
-on some systems, though this naming isn't mentioned in the classical
-documentation.
-.
-.P
-Today, any existing roff system is based on Kernighan's multi-device
-troff.
-.
-The distinction between
-.I troff
-and 
-.I ditroff
-isn't necessary any longer, for each modern
-.I troff
-provides already the complete functionality of
-.IR ditroff .
-.
-On most systems, the name
-.I troff
-is used to denote
-.IR ditroff .
-.
-.P
-The easiest way to use ditroff is the GNU roff system,
-.IR groff .
-The
-.BR groff (@MAN1EXT@)
-program is a wrapper around
-.I (di)troff
-that automatically handles postprocessing.

-.TH GROFF @MAN7EXT@ "@MDATE@" "Groff Version @VERSION@"
-.SH NAME
-groff \- a short reference for the GNU roff language
-.
-.
-.\" --------------------------------------------------------------------
-.SH DESCRIPTION
-.\" --------------------------------------------------------------------
-.
-The name
-.I groff
-stands for
-.I GNU roff
-and is the free implementation of the roff type-setting system.
-.
-See
-.BR roff (@MAN7EXT@)
-for a survey and the background of the groff system.
-.
-.P
-This document gives only short descriptions of the predefined roff
-language elements as used in groff.
-.
-Both the classical features and the groff extensions are provided.
-.
-.P
-Historically, the
-.I roff language
-was called
-.IR troff .
-.I groff
-is compatible with the classical system and provides proper
-extensions.
-.
-So in GNU, the terms
-.IR roff ,
-.IR troff ,
-and
-.I groff language
-could be used as synonyms.
-.
-However
-.I troff
-slightly tends to refer more to the classical aspects, whereas
-.I groff
-emphasizes the GNU extensions, and
-.I roff
-is the general term for the language.
-.
-.P
-This file is only a short version of the complete documentation that
-is found in the
-.I groff
-.BR info (1)
-file, which contains more detailed, actual, and concise information.
-.
-.P
-The general syntax for writing groff documents is relatively easy, but
-writing extensions to the roff language can be a bit harder.
-.
-.P
-The roff language is line-oriented.
-.
-There are only two kinds of lines, control lines and text lines.
-.
-The control lines start with a control character, by default a period
-.dquoted_char .
-or a single quote
-.dquoted_char ' ;
-all other lines are text lines.
-.
-.P
-.B Control lines
-represent commands, optionally with arguments.
-.
-They have the following syntax.
-.
-The leading control character can be followed by a command name;
-arguments, if any, are separated by blanks from the command name and
-among themselves, for example,
-.RS
-.
-.P
-.Text .command_name arg1 arg2
-.RE
-.
-.P
-For indentation, any number of space or tab characters can be inserted
-between the leading control character and the command name, but the
-control character must be on the first position of the line.
-.
-.P
-.B Text lines
-represent the parts that will be printed.
-They can be modified by escape sequences, which are recognized by a
-leading backslash
-.squoted_char \[rs] .
-These are in-line or even in-word formatting elements or functions.
-.
-Some of these take arguments separated by single quotes
-.dquoted_char ' ,
-others are regulated by a length encoding introduced by an open
-parenthesis
-.squoted_char (
-or enclosed in brackets
-.squoted_char [
-and
-.squoted_char ] .
-.
-.P
-The roff language provides flexible instruments for writing language
-extension, such as macros.
-.
-When interpreting macro definitions, the roff system enters a special
-operating mode, called the
-.BR "copy mode" .
-.
-.P
-The copy mode behavior can be quite tricky, but there are some rules
-that ensure a safe usage.
-.
-.IP 1.
-Printable backslashes must be denoted as
-.esc e .
-To be more precise,
-.esc e
-represents the current escape character.
-.
-To get a backslash glyph, use
-.esc (rs
-or
-.esc [rs] .
-.IP 2.
-Double all backslashes.
-.IP 3.
-Begin all text lines with the special non-spacing character
-.esc & .
-.
-.P
-This does not produce the most efficient code, but it should work as a
-first measure.
-.
-For better strategies, see the groff info file and
-.BR groff_tmac (@MAN5EXT@).
-.
-.P
-Reading roff source files is easier, just reduce all double backslashes
-to a single one in all macro definitions.
-.
-.
-.\" --------------------------------------------------------------------
-.SH "GROFF ELEMENTS"
-.\" --------------------------------------------------------------------
-.
-The roff language elements add formatting information to a text file.
-.
-The fundamental elements are predefined commands and variables that
-make roff a full-blown programming language.
-.
-.P
-There are two kinds of roff commands, possibly with arguments.
-.B Requests
-are written on a line of their own starting with a dot
-.squoted_char .
-or a
-.dquoted_char ' ,
-whereas
-.B Escape sequences
-are in-line functions and in-word formatting elements starting with a
-backslash
-.squoted_char \[rs] .
-.
-.P
-The user can define her own formatting commands using the
-.request de
-request.
-.
-These commands are called
-.BR macros ,
-but they are used exactly like requests.
-.
-Macro packages are pre-defined sets of macros written in the groff
-language.
-.
-A user's possibilities to create escape sequences herself is very
-limited, only special characters can be mapped.
-.
-.P
-The groff language provides several kinds of variables with
-different interfaces.
-.
-There are pre-defined variables, but the user can define her own
-variables as well.
-.
-.P
-.B String
-variables store character sequences.
-.
-They are set with the
-.request ds
-request and retrieved by the
-.esc *
-escape sequences.
-.
-Strings can have variables.
-.
-.P
-.B Register
-variables can store numerical values, numbers with a scale unit, and
-occasionally string-like objects.
-.
-They are set with the
-.request nr
-request and retrieved by the
-.esc n
-escape sequences.
-.
-.P
-.B Environments
-allow the user to temporarily store global formatting parameters like
-line length, font size, etc.\& for later reuse.
-.
-This is done by the
-.request ev
-request.
-.
-.P
-.B Fonts
-are identified either by a name or by an internal number.
-.
-The current font is chosen by the
-.request ft
-request or by the
-.esc f
-escape sequences.
-.
-Each device has special fonts, but the following fonts are available
-for all devices.
-.B R
-is the standard font Roman.
-.B B
-is its
-.B bold
-counterpart.
-.
-The
-.I italic
-font is called
-.B I
-and is available everywhere, but on text devices it is displayed as an
-underlined Roman font.
-.
-For the graphical output devices, there exist constant-width pendants
-of these fonts,
-.BR CR ,
-.BR CI ,
-and
-.BR CB .
-On text devices, all characters have a constant width anyway.
-.
-.P
-Moreover, there are some advanced roff elements.
-.
-A
-.B diversion
-stores information into a macro for later usage.
-.
-A
-.B trap
-is a positional condition like a certain number of lines from page top
-or in a diversion or in the input.
-.
-Some action can be prescribed to be run automatically when the
-condition is met.
-.
-.P
-More detailed information and examples can be found in the groff info
-file.
-.
-.
-.\" --------------------------------------------------------------------
-.SH "CONTROL CHARACTERS"
-.\" --------------------------------------------------------------------
-.
-There is a small set of characters that have a special controlling
-task in certain conditions.
-.
-.TP
-.character .
-A dot is only special at the beginning of a line or after the
-condition in the requests
-.request if ,
-.request ie ,
-.request el ,
-and
-.request while .
-There it is the control character that introduces a request (or macro).
-.
-The special behavior can be delayed by using the
-.esc .
-escape.
-.
-By using the 
-.request cc
-request, the control character can be set to a different character,
-making the dot
-.squoted_char .
-a non-special character.
-.IP ""
-In all other positions, it just means a dot character.

-In text paragraphs, it is advantageous to start each sentence at a
-line of its own.
-.
-.TP
-.character '
-The single quote has two controlling tasks.
-.
-At the beginning of a line and in the conditional requests it is the
-non-breaking control character.
-.
-That means that it introduces a request like the dot, but with the
-additional property that this request doesn't cause a linebreak.
-.
-By using the 
-.request c2
-request, the non-break control character can be set to a different
-character.
-.
-.IP ""
-As a second task, it is the most commonly used argument separator in
-some functional escape sequences (but any pair of characters not part
-of the argument will work).
-.
-In all other positions, it denotes the single quote or apostrophe
-character.
-.
-Groff provides a printable representation with the

-.
-.TP
-.character \[dq]
-The double quote is used to enclose arguments in requests, macros, and
-strings.
-.
-In the
-.request ds
-and
-.request as
-requests, a leading double quote in the argument will be stripped off,
-making everything else afterwards the string to be defined (enabling
-leading whitespace).
-.
-The escaped double quote
-.esc \[dq]
-introduces a comment.
-.
-Otherwise, it is not special.
-.
-Groff provides a printable representation with the
-.esc (dq
-escape sequence.
-.
-.TP
-.character \[rs]
-The backslash usually introduces an escape sequence (this can be
-changed with the
-.request ec
-request).
-.
-A printed version of the escape character is the
-.esc e
-escape; a backslash glyph can be obtained by
-.esc (rs .
-.TP
-.character (
-The open parenthesis is only special in escape sequences when
-introducing an escape name or argument consisting of exactly two
-characters.
-.
-In groff, this behavior can be replaced by the \f[CB][]\f[] construct.
-.TP
-.character [
-The opening bracket is only special in groff escape sequences; there
-it is used to introduce a long escape name or long escape argument.
-.
-Otherwise, it is non-special, e.g.\& in macro calls.
-.TP
-.character ]
-The closing bracket is only special in groff escape sequences; there
-it terminates a long escape name or long escape argument.
-.
-Otherwise, it is non-special.
-.TP
-\f[CI]space\f[]
-Space characters are only functional characters.
-.
-They separate the arguments in requests, macros, and strings, and the words
-in text lines.
-.
-They are subject to groff's horizontal spacing calculations.
-.
-To get a defined space width, escape sequences like
-.squoted_char "\[rs]\ "
-(this is the escape character followed by a space),
-.esc | ,
-.esc ^ ,
-or
-.esc h
-should be used.
-.
-.IP \f[CI]newline\f[]
-In text paragraphs, newlines mostly behave like space characters.
-.
-Continuation lines can be specified by an escaped newline, i.e., by
-specifying a backslash
-.squoted_char \[rs]
-as the last character of a line.
-.IP \f[CI]tab\f[]
-If a tab character occurs during text the interpreter makes a
-horizontal jump to the next pre-defined tab position.
-.
-There is a sophisticated interface for handling tab positions.

-.SH REQUESTS
-.\" --------------------------------------------------------------------
-.
-This section provides a short reference for the predefined requests.
-.
-In groff, request and macro names can be arbitrarily long.
-.
-No bracketing or marking of long names is needed.
-.
-.P
-Most requests take one or more arguments.
-.
-The arguments are separated by space characters (no tabs!); there is
-no inherent limit for their length or number.
-.
-An argument can be enclosed by a pair of double quotes.
-.
-This is very handy if an argument contains space characters, e.g.,
-.RI \[dq] "arg with space" \[dq]
-denotes a single argument.
-.
-.P
-Some requests have optional arguments with a different behaviour.
-.
-Not all of these details are outlined here.
-.
-Refer to the groff info file and
-.BR groff_diff (@MAN7EXT@)
-for all details.
-.
-.P
-In the following request specifications, most argument names were
-chosen to be descriptive.
-.
-Only the following denotations need clarification.
-.
-.P
-.PD 0

-.I n
-is a numerical expression that evaluates to an integer value.
-.
-.TPx
-.I N
-is an arbitrary numerical expression, signed or unsigned.
-.
-.TPx
-.I \[+-]N
-has three meanings depending on its sign, described below.
-.
-.RE
-.PD
-.
-.P
-If an expression defined as
-.I \[+-]N
-starts with a
-.squoted_char +
-sign the resulting value of the expression will be added to an already
-existing value inherent to the related request, e.g.\& adding to a number
-register.
-.
-If the expression starts with a
-.squoted_char -
-the value of the expression will be subtracted from the request value.
-.
-.P
-Without a sign,
-.I N
-replaces the existing value directly.

-.SH "ESCAPE SEQUENCES"
-.\" --------------------------------------------------------------------
-.
-Escape sequences are in-line language elements usually introduced by a
-backslash
-.squoted_char \[rs]
-and followed by an escape name and sometimes by a required argument.
-.
-Input processing is continued directly after the escaped character or
-the argument resp.\& without an intervening separation character.
-.
-So there must be a way to determine the end of the escape name and the
-end of the argument.
-.
-.P
-This is done by enclosing names (escape name and arguments consisting
-of a variable name) by a pair of brackets
-.BI \[lB] name \[rB] 
-and constant arguments (number expressions and characters) by
-apostrophes (ASCII 0x27) like
-.BI \[cq] constant \[cq] \f[R].
-.
-.P
-There are abbreviations for short names.
-.
-Two character escape names can be specified by an opening parenthesis
-like
-.esc ( xy
-without a closing counterpart.
-.
-And all one-character names different from the special characters
-.squoted_char [
-and
-.squoted_char (
-can even be specified without a marker in the form
-.esc c .
-.
-.P
-Constant arguments of length\~1 can omit the marker apostrophes, too,
-but there is no two-character analogue.
-.
-.P
-While 1-character escape sequences are mainly used for in-line
-functions and system related tasks, the 2-letter names following the
-.esc (
-construct are used for special characters predefined by the roff system.
-.
-Escapes sequences with names of more than two characters
-.esc[] "" name
-denote user defined named characters (see the
-.request char
-request).

-.\" --------------------------------------------------------------------
-.
-Registers are variables that store a value.
-In groff, most registers store numerical values (see section
-.B NUMERICAL EXPRESSIONS
-above), but some can also hold a string value.
-.
-.P
-Each register is given a name.
-Arbitrary registers can be defined and set with the request
-.request nr
-.IR register .
-.
-.P
-The value stored in a register can be retrieved by the escape sequences
-introduced by
-.esc n .
-.
-.P
-Most useful are predefined registers.
-.
-In the following the notation
-.I name
-is used to refer to a register called
-.register name
-to make clear that we speak about registers.
-.
-Please keep in mind that the
-.esc[] n ""
-decoration is not part of the register name.

-.BR man (1)
-program or the roff formatter).
-.
-Glyphs not available for the device that
-is being used to print or view this manual page will be marked with
-.ie \n(.g `(N/A)'; the device currently used is `\*(.T'.
-.el `(N/A)'.
-.
-.
-.P
-In the actual version, 
-.B groff
-provides only \%8-bit characters for direct input and named entities
-for further glyphs.
-.
-On ASCII platforms, input character codes in the range 0 to 127 (decimal)
-represent the usual \%7-bit ASCII characters, while codes between 127
-and 255 are interpreted as the corresponding characters in the
-.I \%Latin-1
-.RI ( \%ISO-8859-1 )
-code set by default.
-.
-This mapping is contained in the file \f(CWlatin1.tmac\fP
-and can be changed by loading a different input encoding.
-.
-Note that some of the input characters are reserved by
-.BR groff ,
-either for internal use or for special input purposes.
-.
-On EBCDIC platforms, only code page
-.B cp1047
-is supported (which contains the same characters as \%Latin-1; the
-input encoding file is called \f(CWcp1047.tmac\fP).
-.
-Again, some input characters are reserved for internal and special purposes.
-.
-It is rather straightforward (for the experienced user) to set up other
-\%8-bit encodings like
-.IR \%Latin-2 ;
-since
-.B groff
-will use Unicode in the next major version, no additional encodings
-are provided.
-.
-.
-.P
-All roff systems provide the concept of named glyphs.
-.
-In traditional roff systems, only names of length\ 2 were used, while
-groff also provides support for longer names.
-.
-It is strongly suggested that only named glyphs are used for all
-character representations outside of the printable \%7-bit ASCII range.
-.
-.
-.P
-Some of the predefined groff escape sequences (with names of length\ 1)
-also produce single characters; these exist for historical reasons or
-are printable versions of syntactical characters.
-.
-They include `\f(CW\e\e\fP', `\f(CW\e\'\fP', `\f(CW\e`\fP', `\f(CW\e-\fP',
-`\f(CW\e.\fP', and `\f(CW\ee\fP'; see
-.BR groff (@MAN7EXT@).
-.
-.
-.P
-In groff, all of these different types of characters and glyphs can be
-tested positively with the `\f(CW.if\ c\fP' conditional.

-.
-In this section, the glyphs in groff are specified in tabular
-form.
-.
-The meaning of the columns is as follows.
-.
-.
-.TP
-.I "Output"
-shows how the glyph is printed for the current device; although
-this can have quite a different shape on other devices, it always
-represents the same glyph.
-.
-.
-.TP
-.I "Input name"
-specifies how the glyph is input either directly by a key on the
-keyboard, or by a groff escape sequence.
-.
-.
-.TP
-.I "Input code"
-applies to glyphs which can be input with a single character, and
-gives the ISO \%Latin-1 decimal code of that input character.
-.
-Note that this code is equivalent to the lowest 256 Unicode characters,
-including \%7-bit ASCII in the range 0 to\ 127.
-.
-.
-.TP
-.I "PostScript name"
-gives the usual PostScript name of the glyph.
-.
-.
-.TP
-.I "Unicode decomposed"
-is the glyph name used in composite glyph names.

-.SS "Named Glyphs"
-.\" --------------------------------------------------------------------
-.
-Glyph names can be embedded into the document text by using escape
-sequences.
-.
-.BR groff (@MAN7EXT@)
-describes how these escape sequences look.
-.
-Glyph names can consist of quite arbitrary characters from the
-ASCII or \%Latin-1 code set, not only alphanumeric characters.
-.
-Here some examples:
-.
-.TP
-\f(CW\e\fP\fIc\fP
-A glyph having the name
-.IR c ,
-which consists of a single character (length\ 1).
-.
-.TP
-\f(CW\e(\fP\fIch\fP
-A glyph having the 2-character name
-.IR ch .
-.
-.TP
-\f(CW\e[\fP\fIchar_name\fP\f(CW]\fP
-A glyph having the name
-.I char_name
-(having length 1, 2, 3, .\|.\|.).
-.
-.TP
-\f(CW\e[\fP\fIbase_glyph composite_1 composite_2 .\|.\|.\fP\f(CW]\fP
-A composite glyph; see below for a more detailed description.
-.
-.
-.P
-In groff, each \%8-bit input character can also referred to by the construct
-`\f(CW\e[char\fP\fIn\fP\f(CW]\fP' where
-.I n
-is the decimal code of the character, a number between 0 and\ 255
-without leading zeros (those entities are
-.I not
-glyph names).
-.
-They are normally mapped onto glyphs using the \f(CW.trin\fP request.
-.
-Another special convention is the handling of glyphs with names directly
-derived from a Unicode code point; this is discussed below.
-.
-Moreover, new glyph names can be created by the \f(CW.char\fP request; see
-.BR groff (@MAN7EXT@).
-.
-.P
-In the following, a plus sign in the `Notes' column indicates that this
-particular glyph name appears in the PS version of the original troff

-Another complication is the fact that some glyphs which represent bracket
-pieces in original troff can be used for other mathematical symbols also,
-for example `lf' and `rf' which provide the `floor' operator.
-.
-Other devices (most notably for DVI output) don't unify such glyphs.
-.
-For this reason, the four glyphs `lf', `rf', `lc', and `rc' are not
-unified with similarly looking bracket pieces.
-.
-In
-.BR groff ,
-only glyphs with long names are guaranteed to pile up correctly for all
-devices (provided those glyphs exist).

-These glyphs are intended for technical use, not for real Greek; normally,
-the uppercase letters have upright shape, and the lowercase ones are
-slanted.
-.
-There is a problem with the mapping of letter phi to Unicode.
-.
-Prior to Unicode version\ 3.0, the difference between U+03C6, GREEK
-SMALL LETTER PHI, and U+03D5, GREEK PHI SYMBOL, was not clearly described;
-only the glyph shapes in the Unicode book could be used as a reference.
-.
-Starting with Unicode\ 3.0, the reference glyphs have been exchanged and
-described verbally also: In mathematical context, U+03D5 is the stroked
-variant and U+03C5 the curly glyph.
-.
-Unfortunately, most font vendors didn't update their fonts to
-this (incompatible) change in Unicode.
-.
-At the time of this writing (February 2003), it is not clear yet whether
-the Adobe Glyph Names `phi' and `phi1' also change its meaning if used for
-mathematics, thus compatibility problems are likely to happen \(en being
-conservative, groff currently assumes that `phi' in a PostScript symbol
-font is the stroked version.
-.P
-In groff, symbol `\f(CW\e[*f]\fP' always denotes the stroked version of
-phi, and `\f(CW\e[+f]\fP' the curly variant.

-.\" --------------------------------------------------------------------
-.
-This manual page describes the language differences between
-.IR groff ,
-the GNU
-.I roff
-text processing system and the classical
-.I roff
-formatter of the freely available Unix\~7 of the 1970s, documented in
-the
-.I Troff User's Manual
-by
-.I Osanna
-and
-.IR Kernighan .
-This inludes the roff language as well as the intermediate output
-format (troff output).
-.
-.P
-The section
-.I SEE ALSO
-gives pointers to both the classical
-.I roff
-and the modern
-.I groff
-documentation.
-.

-.SH "GROFF LANGUAGE"
-.\" --------------------------------------------------------------------
-.
-In this section, all additional features of
-.I groff
-compared to the classical Unix\~7
-.I troff
-are described in detail.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Long names"
-.\" --------------------------------------------------------------------
-.
-The names of number registers, fonts, strings/\:macros/\:diversions,
-special characters (glyphs), and colors can be of any length.
-.
-In escape sequences, additionally to the classical
-.BI ( xx
-construction for a two-character name, you can use
-.BI [ xxx ]
-for a name of arbitrary length.
-.
-.TP
-.BI \[rs][ xxx ]
-Print the special character (glyph) called
-.IR xxx .
-.
-.TP
-.BI \[rs][ "comp1 comp2 .\|.\|." ]
-Print composite glyph consisting of multiple components.
-.
-Example: `\[rs][A\~ho]' is capital letter A with ogonek which finally maps
-to glyph name `u0041_0328'.
-.
-See the
-.I groff info file
-for details how a glyph name for a composite glyph is constructed, and
-.BR groff_char (@MAN7EXT@)
-for list of glyph name components used composite glyph names.
-.

-.\" --------------------------------------------------------------------
-.SS "Fractional pointsizes"
-.\" --------------------------------------------------------------------
-.
-A
-.I scaled point
-is equal to
-.B 1/sizescale
-points, where
-.B sizescale
-is specified in the
-.B DESC
-file (1 by default).
-.
-There is a new scale indicator
-.B z
-that has the effect of multiplying by sizescale.
-.
-Requests and escape sequences in troff interpret arguments that
-represent a pointsize as being in units of scaled points, but they
-evaluate each such argument using a default scale indicator of
-.BR z .
-Arguments treated in this way are the argument to the
-.B ps
-request, the third argument to the
-.B cs
-request, the second and fourth arguments to the
-.B tkf
-request, the argument to the
-.B \[rs]H
-escape sequence, and those variants of the
-.B \[rs]s
-escape sequence that take a numeric expression as their argument.
-.
-.P
-For example, suppose sizescale is 1000; then a scaled point will be
-equivalent to a millipoint; the call
-.B .ps\ 10.25
-is equivalent to
-.B .ps\ 10.25z
-and so sets the pointsize to 10250 scaled points, which is equal to
-10.25 points.
-.
-.P
-The number register
-.B \[rs]n[.s]
-returns the pointsize in points as decimal fraction.
-.
-There is also a new number register
-.B \[rs]n[.ps]
-that returns the pointsize in scaled points.
-.
-.P
-It would make no sense to use the
-.B z
-scale indicator in a numeric expression whose default scale indicator
-was neither
-.B u
-nor
-.BR z ,
-and so
-.B troff
-disallows this.
-.
-Similarly it would make no sense to use a scaling indicator other than
-.B z
-or
-.B u
-in a numeric expression whose default scale indicator was
-.BR z ,
-and so
-.B troff
-disallows this as well.
-.
-.P
-There is also new scale indicator\~\c
-.B s
-which multiplies by the number of units in a scaled point.
-.
-So, for example,
-.B \[rs]n[.ps]s
-is equal to
-.BR 1m .
-Be sure not to confuse the
-.B s
-and
-.B z
-scale indicators.

-The current font is the index of a font position and so is also either
-a font or a style.
-.
-When it is a style, the font that is actually used is the font the
-name of which is the concatenation of the name of the current family
-and the name of the current style.
-.
-For example, if the current font is\~1 and font position\~1 is
-associated with style\~\c

-Like the word space size, the sentence space is in units of
-one twelfth of the spacewidth parameter for the current font.
-.
-Initially both the word space size and the sentence
-space size are\~12.

-Contrary to UNIX troff, GNU troff handles this request in nroff mode

-The sentence space size is used in two circumstances.

-.B @g@troff
-predefines a single (read/write) string-based register,
-.BR \[rs]*(.T ,
-which contains the argument given to the
-.B \-T
-command line option, namely the current output device (for example,
-.I latin1
-or
-.IR ascii ).
-Note that this is not the same as the (read-only) number register
-.B \[rs]n[.T]
-which is defined to be\~1 if
-.B troff
-is called with the
-.B \-T
-command line option, and zero otherwise.
-.
-This behaviour is different to UNIX troff.
-.
-.P
-Fonts not listed in the
-.SM DESC
-file are automatically mounted on the next available font position
-when they are referenced.
-.
-If a font is to be mounted explicitly with the
-.B fp
-request on an unused font position, it should be mounted on the first
-unused font position, which can be found in the
-.B \[rs]n[.fp]
-register; although
-.B troff
-does not enforce this strictly, it will not allow a font to be mounted
-at a position whose number is much greater than that of any currently

-.P
-Interpolating a string does not hide existing macro arguments.
-.

-between them.
-.
-.P
-In a string comparison in a condition, characters that appear at
-different input levels to the first delimiter character will not be
-recognised as the second or third delimiters.
-.
-This applies also to the
-.B tl
-request.
-.
-In a
-.B \[rs]w
-escape sequence, a character that appears at a different input level
-to the starting delimiter character will not be recognised as the
-closing delimiter character.

-.BR \[rs]C ,
-.BR \[rs]l ,
-.BR \[rs]L ,
-.BR \[rs]o ,

-.BR \[rs]Z .
-.
-When decoding a macro or string argument that is delimited by double
-quotes, a character that appears at a different input level to the starting
-delimiter character will not be recognised as the closing delimiter
-character.
-.
-The implementation of
-.B \[rs]$@
-ensures that the double quotes surrounding an argument will appear the
-same input level, which will be different to the input level of the
-argument itself.
-.
-In a long escape name
-.B ]
-will not be recognized as a closing delimiter except when it occurs at
-the same input level as the opening
-.BR ] .
-.
-In compatibility mode, no attention is paid to the input-level.

-.
-.TP
-.BI .if\ F f
-True if font

-intermediate shades of gray.
-.
-This applies only to solid circles, solid ellipses and solid
-polygons.
-.
-By default, a level of 1000 will be used.
-.
-Whatever color a solid object has, it should completely obscure
-everything beneath it.
-.
-A value greater than 1000 or less than 0 can also be used: this means
-fill with the shade of gray that is currently being used for lines and

-.
-Normally this will be black, but some drivers may provide a way of

-.
-.IP
-The corresponding

-where

-Unix troff will treat each of the $x sub i$ as a horizontal quantity,
-and each of the $y sub i$ as a vertical quantity and will assume that
-the width of the drawn object is $sum from i=1 to n x sub i$,
-and that the height is $sum from i=1 to n y sub i$.
-.
-(The assumption about the height can be seen by examining the
-.B st

-command to contain newlines: when outputting the argument to the
-.B x\ X
-command, GNU troff will follow each newline in the argument with a
-.B +
-character (as usual, it will terminate the entire argument with a
-newline); thus if the line after the line containing the
-.B x\ X
-command starts with
-.BR + ,
-then the newline ending the line containing the
-.B x\ X
-command should be treated as part of the argument to the
-.B x\ X
-command, the
-.B +
-should be ignored, and the part of the line following the
-.B +
-should be treated like the part of the line following the
-.B x\ X
-command.

-The first three output commands are guaranteed to be:
-.IP
-.BI x\ T\  device

-.SH INCOMPATIBILITIES
-.\" --------------------------------------------------------------------
-.
-In spite of the many extensions, groff has retained compatibility to
-classical troff to a large degree.
-.
-For the cases where the extensions lead to collisions, a special
-compatibility mode with the restricted, old functionality was created
-for groff.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Groff Language"
-.\" --------------------------------------------------------------------
-.
-.I groff
-provides a
-.B compatibility mode
-that allows to process roff code written for classical
-.B troff
-or for other implementations of roff in a consistent way.
-.
-.P
-Compatibility mode can be turned on with the
-.option \-C
-command line option, and turned on or off with the
-.request .cp
-request.
-.
-The number register
-.esc n(.C
-is\~1 if compatibility mode is on, 0\~otherwise.
-.
-.P
-This became necessary because the GNU concept for long names causes
-some incompatibilities.
-.I Classical troff
-interprets
-.IP
-.request .dsabcd
-.
-.P
-as defining a string
-.B ab
-with contents
-.BR cd .
-In
-.IR groff
-mode, this will be considered as a call of a macro named
-.request dsabcd .
-.
-.P
-Also
-.I classical troff
-interprets
-.esc *[
-or
-.esc n[
-as references to a string or number register called
-.request [
-while
-.I groff
-takes this as the start of a long name.
-.
-.P
-In
-.IR "compatibility mode" ,
-groff interprets these things in the traditional way; so long
-names are not recognized.
-.
-.P
-On the other hand, groff in
-.I GNU native mode
-does not allow to use the single-character escapes
-.esc \[rs]
-(backslash),
-.esc |
-(vertical bar),
-.esc ^
-(caret),
-.esc &
-(ampersand),
-.esc {
-(opening brace),
-.esc }
-(closing brace),
-.squoted "\[rs]\ "
-(space),
-.esc '
-(single quote),
-.esc `
-(backquote),
-.esc \-
-(minus),
-.esc _
-(underline),
-.esc !
-(bang),
-.esc %
-(percent),
-and
-.esc c
-(character c) in names of strings, macros, diversions, number
-registers, fonts or environments, whereas
-.I classical troff
-does.
-.
-.P
-The
-.esc A
-escape sequence can be helpful in avoiding these escape sequences in
-names.
-.
-.P
-Fractional pointsizes cause one noteworthy incompatibility.
-.
-In
-.I classical
-.IR troff ,
-the
-.request ps
-request ignores scale indicators and so
-.RS
-.P
-.B .ps\~10u
-.RE
-.
-.P
-will set the pointsize to 10\~points, whereas in groff native mode the
-pointsize will be set to 10\~scaled points.
-.
-.P
-In
-.IR groff ,
-there is a fundamental difference between unformatted input
-characters, and formatted output characters (glyphs).
-.
-Everything that affects how a glyph will be output is
-stored with the glyph; once a glyph has been
-constructed it is unaffected by any subsequent requests that are
-executed, including the
-.request bd ,
-.request cs ,
-.request tkf ,
-.request tr ,
-or
-.request fp
-requests.
-.
-.P
-Normally glyphs are constructed from input characters at
-the moment immediately before the glyph is added to the current
-output line.
-.
-Macros, diversions and strings are all, in fact, the same type of
-object; they contain lists of input characters and glyphs
-in any combination.
-.
-.P
-Special characters can be both; before being added to the output, they
-act as input entities, afterwards they denote glyphs.
-.
-.P
-A glyph does not behave like an input character for the
-purposes of macro processing; it does not inherit any of the special
-properties that the input character from which it was constructed
-might have had.
-.
-The following example will make things clearer.
-.
-.P
-.RS
-.nf
-.ft CB
-.Text .di x
-.Text \[rs]\[rs]\[rs]\[rs]
-.Text .br
-.Text .di
-.Text .x
-.ft
-.fi
-.RE
-.
-.P
-With
-.I GNU troff
-this will be printed as
-.esc \[rs] .
-So each pair of input backslashes
-.squoted \[rs]\[rs]
-is turned into a single output backslash glyph
-.squoted \[rs]
-and the resulting output backslashes are not interpreted as escape
-characters when they are reread.
-.
-.P
-.I Classical troff
-would interpret them as escape characters when they were reread and
-would end up printing a single backslash
-.squoted \[rs] .
-.
-.P
-In GNU, the correct way to get a printable version of the backslash
-character
-.squoted \[rs]
-is the
-.esc (rs
-escape sequence, but classical troff does not provide a clean feature
-for getting a non-syntactical backslash.
-.
-A close method is the printable version of the current escape
-character using the
-.esc e
-escape sequence; this works if the current escape character is not
-redefined.
-.
-It works in both GNU mode and compatibility mode, while dirty tricks
-like specifying a sequence of multiple backslashes do not work
-reliably; for the different handling in diversions, macro definitions,
-or text mode quickly leads to a confusion about the necessary number of
-backslashes.
-.
-.P
-To store an escape sequence in a diversion that will be interpreted
-when the diversion is reread, either the traditional
-.esc !
-transparent output facility or the
-new
-.esc ?
-escape sequence can be used.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Intermediate Output"
-.\" --------------------------------------------------------------------
-.
-The groff intermediate output format is in a state of evolution.
-.
-So far it has some incompatibilities, but it is intended to establish
-a full compatibility to the classical troff output format.
-.
-Actually the following incompatibilities exist:
-.
-.Topic
-The positioning after the drawing of the polygons conflicts with the
-classical definition.
-.
-.Topic
-The intermediate output cannot be rescaled to other devices as
-classical "device-independent" troff did.

-.SH NAME
-groff_font \- format of groff device and font description files
-.
-.
-.SH DESCRIPTION
-The groff font format is roughly a superset of the ditroff
-font format.
-.
-The font files for device
-.I name
-are stored in a directory
-.BI dev name\c
-\&.
-.
-There are two types of file: a
-device description file called
-.B DESC
-and for each font
-.I F
-a font file called
-.IR F .
-.
-These are text files;
-unlike the ditroff font format,
-there is no associated binary format.
-.
-.
-.SS DESC file format
-.
-The DESC file can contain the following types of line as shown below.
-.
-Later entries in the file override previous values.
-.
-.TP
-.B charset
-This line and everything following in the file are ignored.
-.
-It is allowed for the sake of backwards compatibility.
-.
-.TP
-.BI family\  fam
-The default font family is
-.IR fam .
-.
-.TP
-.BI fonts\  n\ F1\ F2\ F3\|.\|.\|.\|Fn
-Fonts
-.I F1\|.\|.\|.\|Fn
-will be mounted in the font positions 
-.IR m +1,\|.\|.\|., m + n
-where
-.I m
-is the number of styles.
-.
-This command may extend over more than one line.
-.
-A font name of
-.B 0
-will cause no font to be mounted on the corresponding font position.
-.
-.TP
-.BI hor\  n
-The horizontal resolution is
-.I n
-machine units.
-.
-.TP
-.BI image_generator\  string
-Needed for
-.B grohtml
-only.
-It specifies the program to generate PNG images from
-PostScript input.
-Under GNU/Linux this is usually
-.I gs
-but under other systems (notably cygwin) it might be set to another name.
-.
-.TP
-.BI paperlength\  n
-The physical vertical dimension of the output medium in machine units.
-.
-This isn't used by
-.B troff
-itself but by output devices.
-.
-Deprecated.
-.
-Use
-.B papersize
-instead.
-.
-.TP
-.BI papersize\  string
-Select a paper size.
-.
-Valid values for
-.I string
-are the ISO paper types A0-A7, B0-B7, C0-C7, D0-D7, DL, and the US paper
-types letter, legal, tabloid, ledger, statement, executive, com10, and
-monarch.
-.
-Case is not significant for
-.IR string
-if it holds predefined paper types.
-.
-Alternatively,
-.I string
-can be a file name (e.g.\& `/etc/papersize'); if the file can be opened,
-.B groff
-reads the first line and tests for the above paper sizes.
-.
-Finally,
-.I string
-can be a custom paper size in the format
-.IB length , width
-(no spaces before and after the comma).
-.
-Both
-.I length
-and
-.I width
-must have a unit appended; valid values are `i' for inches, `c' for
-centimeters, `p' for points, and `P' for picas.
-.
-Example:
-.BR 12c,235p .
-.
-An argument which starts with a digit is always treated as a custom paper
-format.
-.
-.B papersize
-sets both the vertical and horizontal dimension of the output medium.
-.
-.IP
-More than one argument can be specified;
-.B groff
-scans from left to right and uses the first valid paper specification.
-.
-.TP
-.BI paperwidth\  n
-The physical horizontal dimension of the output medium in machine units.
-.
-Deprecated.
-.
-Use
-.B papersize
-instead.
-.
-This isn't used by
-.BR troff
-itself but by output devices.
-.
-.TP
-.B pass_filenames
-Make troff tell the driver the source file name being processed.
-.
-This is achieved by another tcommand:
-.B F
-.IR filename .
-.
-.TP
-.BI postpro\  program
-Use
-.I program
-as the postprocessor.
-.
-.TP
-.BI prepro\  program
-Call
-.I program
-as a preprocessor.
-.
-.TP
-.BI print\  program
-Use
-.I program
-as the spooler program for printing.
-.
-If omitted, the
-.B \-l
-and
-.B \-L
-options of
-.B groff
-are ignored.
-.
-.TP
-.BI res\  n
-There are
-.I n
-machine units per inch.
-.
-.TP
-.BI sizes\  s1\ s2\|.\|.\|.\|sn\  0
-This means that the device has fonts at
-.IR s1 ,
-.IR s2 ,\|.\|.\|.\| sn
-scaled points.
-.
-The list of sizes must be terminated by a
-.BR 0 .
-.
-Each
-.I si
-can also be a range of sizes
-.IR m \- n .
-.
-The list can extend over more than one line.
-.
-.TP
-.BI sizescale\  n
-The scale factor for pointsizes.
-.
-By default this has a value of 1.
-.
-One
-.I
-scaled point
-is equal to
-one
-.RI point/ n .
-.
-The arguments to the
-.B unitwidth
-and
-.B sizes
-commands are given in scaled points.
-.
-.TP
-.BI styles\  S1\ S2\|.\|.\|.\|Sm
-The first
-.I m
-font positions will be associated with styles
-.IR S1\|.\|.\|.\|Sm .
-.
-.TP
-.B tcommand
-This means that the postprocessor can handle the
-.B t
-and
-.B u
-output commands.
-.
-.TP
-.BI unitwidth\  n
-Quantities in the font files are given in machine units
-for fonts whose point size is
-.I n 
-scaled points.
-.
-.TP
-.B unscaled_charwidths
-Make the font handling module always return unscaled character widths.
-Needed for the
-.B grohtml
-device.
-.
-.TP
-.B use_charnames_in_special
-This command indicates that troff should encode named characters inside
-special commands.
-.
-.TP
-.BI vert\  n
-The vertical resolution is
-.I n
-machine units.
-.
-.LP
-The
-.BR res ,
-.BR unitwidth ,
-.BR fonts ,
-and
-.B sizes
-lines are compulsory.
-.
-Not all commands in the DESC file are used by
-.B troff
-itself; some of the keywords (or even additional ones) are used by
-postprocessors to store arbitrary information about the device.
-.
-.LP
-Here a list of obsolete keywords which are recognized by
-.B groff
-but completely ignored:
-.BR spare1 ,
-.BR spare2 ,
-.BR biggestfont .
-.
-.
-.SS Font file format
-.
-A font file has two sections.
-The first section is a sequence
-of lines each containing a sequence of blank delimited
-words; the first word in the line is a key, and subsequent
-words give a value for that key.
-.
-.TP
-.BI ligatures\  lig1\ lig2\|.\|.\|.\|lign\ \fR[ 0 \fR]
-Characters
-.IR lig1 ,
-.IR lig2 ,\ \|.\|.\|.,\ lign
-are ligatures; possible ligatures are
-.BR ff ,
-.BR fi ,
-.BR fl ,
-.B ffi
-and
-.BR ffl .
-.
-For backwards compatibility, the list of ligatures may be terminated
-with a
-.BR 0.
-.
-The list of ligatures may not extend over more than one line.
-.
-.TP
-.BI name\  F
-The name of the font is
-.IR F .
-.
-.TP
-.BI slant\  n
-The characters of the font have a slant of
-.I n
-degrees.
-.
-(Positive means forward.)
-.
-.TP
-.BI spacewidth\  n
-The normal width of a space is
-.IR n .
-.
-.TP
-.B special
-The font is
-.IR special ;
-this means that when a character is requested that is not present in
-the current font, it will be searched for in any special fonts that
-are mounted.
-.
-.LP
-Other commands are ignored by
-.B troff
-but may be used by postprocessors to store arbitrary information
-about the font in the font file.
-.
-.LP
-The first section can contain comments which start with the
-.B #
-character and extend to the end of a line.
-.
-.LP
-The second section contains one or two subsections.
-.
-It must contain a
-.I charset
-subsection
-and it may also contain a
-.I kernpairs
-subsection.
-.
-These subsections can appear in any order.
-.
-Each subsection starts with a word on a line by itself.
-.
-.LP
-The word
-.B charset
-starts the charset subsection.
-.
-The
-.B charset
-line is followed by a sequence of lines.
-.
-Each line gives information for one character.
-.
-A line comprises a number of fields separated
-by blanks or tabs.
-.
-The format is
-.
-.IP
-.I name metrics type code 
-.RI [ entity_name ]
-.RB [ --
-.IR comment ]
-.
-.LP
-.I name
-identifies the character:
-if
-.I name
-is a single character
-.I c
-then it corresponds to the groff input character
-.IR c ;
-if it is of the form
-.BI \[rs] c
-where c is a single character, then it
-corresponds to the special character
-.BI \[rs][ c ]\fR;
-otherwise it corresponds to the groff input character
-.BI \[rs][ name ]\fR.
-.
-If it is exactly two characters
-.I xx
-it can be entered as
-.BI \[rs]( xx\fR.
-.
-Note that single-letter special characters can't be accessed as
-.BI \[rs] c\fR;
-the only exception is `\[rs]-' which is identical to `\[rs][-]'.
-.
-The name
-.B \-\-\-
-is special and indicates that the character is unnamed;
-such characters can only be used by means of the
-.B \[rs]N
-escape sequence in
-.BR troff .
-.
-.LP
-Groff supports eight-bit characters; however some utilities
-have difficulties with eight-bit characters.
-.
-For this reason, there is a convention that the name
-.BI char n
-is equivalent to the single character whose code is
-.IR n .
-.
-For example,
-.B char163
-would be equivalent to the character with code 163
-which is the pounds sterling sign in ISO Latin-1.
-.
-.LP
-The
-.I type
-field gives the character type:
-.
-.TP
-1
-means the character has a descender, for example, p;
-.
-.TP
-2
-means the character has an ascender, for example, b;
-.
-.TP
-3
-means the character has both an ascender and a descender, for example,
-(.
-.
-.LP
-The
-.I code
-field gives the code which the postprocessor uses to print the character.
-.
-The character can also be input to groff using this code by means of the
-.B \[rs]N
-escape sequence.
-.
-The code can be any integer.
-.
-If it starts with a
-.B 0
-it will be interpreted as octal;
-if it starts with
-.B 0x
-or
-.B 0X
-it will be intepreted as hexadecimal.
-.
-Note, however, that the
-.B \[rs]N
-escape sequence only accepts a decimal integer.
-.
-.LP
-The
-.I entity_name
-field gives an ascii string identifying the glyph which the postprocessor
-uses to print the character.
-.
-This field is optional and has been introduced so that the html device driver
-can encode its character set.
-.
-For example, the character `\[rs][Po]' is represented as `&pound;' in
-html\~4.0.
-.
-.LP
-Anything on the line after the encoding field resp. after `-\&-' will
-be ignored.
-.
-.LP
-The
-.I metrics
-field has the form (in one line; it is broken here for the sake of
-readability):
-.
-.IP
-.I width\c
-.RI [\fB, height\c
-.RI [\fB, depth\c
-.RI [\fB, italic-correction
-.br
-.RI [\fB, left-italic-correction\c
-.RI [\fB, subscript-correction ]]]]]
-.
-.LP
-There must not be any spaces between these subfields.
-.
-Missing subfields are assumed to be 0.
-.
-The subfields are all decimal integers.
-.
-Since there is no associated binary format, these
-values are not required to fit into a variable of type
-.B char
-as they are in ditroff.
-.
-The
-.I width
-subfields gives the width of the character.
-.
-The
-.I height
-subfield gives the height of the character (upwards is positive);
-if a character does not extend above the baseline, it should be
-given a zero height, rather than a negative height.
-.
-The
-.I depth
-subfield gives the depth of the character, that is, the distance
-below the lowest point below the baseline to which the
-character extends (downwards is positive);
-if a character does not extend below above the baseline, it should be
-given a zero depth, rather than a negative depth.
-.
-The
-.I italic-correction
-subfield gives the amount of space that should be added after the
-character when it is immediately to be followed by a character
-from a roman font.
-.
-The
-.I left-italic-correction
-subfield gives the amount of space that should be added before the
-character when it is immediately to be preceded by a character
-from a roman font.
-.
-The
-.I subscript-correction
-gives the amount of space that should be added after a character
-before adding a subscript.
-.
-This should be less than the italic correction.
-.
-.LP
-A line in the charset section can also have the format
-.
-.IP
-.I
-name \fB"
-.
-.LP
-This indicates that
-.I name
-is just another name for the character mentioned in the
-preceding line.
-.
-.LP
-The word
-.B kernpairs
-starts the kernpairs section.
-.
-This contains a sequence of lines of the form:
-.
-.IP
-.I c1 c2 n
-.
-.LP
-This means that when character
-.I c1
-appears next to character
-.I c2
-the space between them should be increased by
-.IR n .
-.
-Most entries in kernpairs section will have a negative value for
-.IR n .

-.\" --------------------------------------------------------------------
-.SH DESCRIPTION
-.\" --------------------------------------------------------------------
-.
-This manual page describes the
-.I intermediate output
-format of the GNU
-.BR roff (@MAN7EXT@)
-text processing system
-.BR groff (@MAN1EXT@).
-.
-This output is produced by a run of the GNU
-.BR @g@troff (@MAN1EXT@)
-program.
-.
-It contains already all device-specific information, but it is not yet
-fed into a device postprocessor program.
-.
-.
-.P
-As the GNU
-.I roff
-processor
-.BR groff (@MAN1EXT@)
-is a wrapper program around
-.B @g@troff
-that automatically calls a
-postprocessor, this output does not show up normally.
-.
-This is why it is called
-.I intermediate
-within the
-.I groff
-.IR system .
-.
-The
-.B groff
-program provides the option
-.B -Z
-to inhibit postprocessing, such that the produced
-.I intermediate output
-is sent to standard output just like calling
-.B @g@troff
-manually.
-.
-.
-.P
-In this document, the term
-.I @g@troff output
-describes what is output by the GNU
-.B @g@troff
-program, while
-.I intermediate output
-refers to the language that is accepted by the parser that prepares
-this output for the postprocessors.
-.
-This parser is smarter on whitespace and implements obsolete elements
-for compatibility, otherwise both formats are the same.
-.
-Both formats can be viewed directly with
-.BR \%gxditview (@MAN1EXT@).
-.
-.
-.P
-The main purpose of the
-.I intermediate output
-concept is to facilitate the development of postprocessors by
-providing a common programming interface for all devices.
-.
-It has a language of its own that is completely different from the
-.BR groff (@MAN7EXT@)
-language.
-.
-While the
-.I groff
-language is a high-level programming language for text processing, the
-.I intermediate output
-language is a kind of low-level assembler language by specifying all
-positions on the page for writing and drawing.
-.
-.
-.P
-The
-.RI pre- groff
-.I roff
-versions are denoted as
-.I classical
-.IR troff .
-The
-.I intermediate output
-produced by
-.B groff
-is fairly readable, while
-.I classical troff
-output was hard to understand because of strange habits that are
-still supported, but not used any longer by
-.I GNU
-.IR @g@troff .
-.
-.
-.\" --------------------------------------------------------------------
-.SH "LANGUAGE CONCEPTS"
-.\" --------------------------------------------------------------------
-.
-During the run of
-.BR @g@troff , 
-the
-.I roff
-input is cracked down to the information on what has to be printed at
-what position on the intended device.
-.
-So the language of the
-.I intermediate output
-format can be quite small.
-.
-Its only elements are commands with or without arguments.
-.
-In this document, the term "command" always refers to the
-.I intermediate output
-language, never to the
-.I roff
-language used for document formatting.
-.
-There are commands for positioning and text writing, for drawing, and
-for device controlling.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Separation"
-.\" --------------------------------------------------------------------
-.
-.I Classical troff output
-had strange requirements on whitespace.
-.
-The
-.B groff
-output parser, however, is smart about whitespace by making it
-maximally optional.
-.
-The whitespace characters, i.e., the
-.IR tab ,
-.IR space ,
-and
-.I newline
-characters, always have a syntactical meaning.
-.
-They are never printable because spacing within the output is always
-done by positioning commands.
-.
-.
-.P
-Any sequence of
-.I space
-or
-.I tab
-characters is treated as a single
-.I syntactical
-.IR space .
-.
-It separates commands and arguments, but is only required when there
-would occur a clashing between the command code and the arguments
-without the space.
-.
-Most often, this happens when variable length command names,
-arguments, argument lists, or command clusters meet.
-.
-Commands and arguments with a known, fixed length need not be
-separated by
-.I syntactical
-.IR space .
-.
-.
-.P
-A line break is a syntactical element, too.
-.
-Every command argument can be followed by whitespace, a comment, or a
-newline character.
-.
-Thus a
-.I syntactical line break
-is defined to consist of optional
-.I syntactical space
-that is optionally followed by a comment, and a newline character.
-.
-.
-.P
-The normal commands, those for positioning and text, consist of a
-single letter taking a fixed number of arguments.
-.
-For historical reasons, the parser allows to stack such commands on
-the same line, but fortunately, in
-.I groff intermediate
-.IR output ,
-every command with at least one argument is followed by a line break,
-thus providing excellent readability.
-.
-.P
-The other commands \[em] those for drawing and device controlling \[em]
-have a more complicated structure; some recognize long command names,
-and some take a variable number of arguments.
-.
-So all
-.B D
-and
-.B x
-commands were designed to request a
-.I syntactical line break
-after their last argument.
-.
-Only one command,
-.RB ` x\ X '
-has an argument that can stretch over several lines, all other
-commands must have all of their arguments on the same line as the
-command, i.e., the arguments may not be splitted by a line break.
-.
-.P
-Empty lines, i.e., lines containing only space and/or a comment, can
-occur everywhere.
-.
-They are just ignored.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Argument Units"
-.\" --------------------------------------------------------------------
-.
-Some commands take integer arguments that are assumed to represent
-values in a measurement unit, but the letter for the corresponding
-.I scale indicator
-is not written with the output command arguments; see
-.BR groff (@MAN7EXT@)
-and the
-.I groff info file
-for more on this topic.
-.
-Most commands assume the scale indicator\~\c
-.unit u ,
-the basic unit of the device, some use\~\c
-.unit z , 
-the
-.I scaled point unit
-of the device, while others, such as the color commands expect plain
-integers.
-.
-Note that these scale indicators are relative to the chosen device.
-.
-They are defined by the parameters specified in the device's
-.I DESC
-file; see
-.BR groff_font (@MAN5EXT@).
-.
-.
-.P
-Note that single characters can have the eighth bit set, as can the
-names of fonts and special characters.
-.
-The names of characters and fonts can be of arbitrary length.
-.
-A character that is to be printed will always be in the current font.
-.
-.
-.P
-A string argument is always terminated by the next whitespace
-character (space, tab, or newline); an embedded
-.B #
-character is regarded as part of the argument, not as the beginning of
-a comment command.
-.
-An integer argument is already terminated by the next non-digit
-character, which then is regarded as the first character of the next
-argument or command.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Document Parts"
-.\" --------------------------------------------------------------------
-A correct
-.I intermediate output
-document consists of two parts, the
-.I prologue
-and the
-.IR body .
-.
-.P
-The task of the
-.I prologue
-is to set the general device parameters using three exactly specified
-commands.
-.
-The
-.I groff prologue
-is guaranteed to consist of the following three lines (in that order):
-.RS
-.P
-.B x\ T
-.I device
-.br
-.B x\ res
-.I n\ h\ v
-.br
-.B x init
-.RE
-.P
-with the arguments set as outlined in the section
-.BR "Device Control Commands" .
-.
-But the parser for the
-.I intermediate output
-format is able to swallow additional whitespace and comments as well.
-.
-.
-.P
-The
-.I body
-is the main section for processing the document data.
-.
-Syntactically, it is a sequence of any commands different from the
-ones used in the
-.IR prologue .
-.
-Processing is terminated as soon as the first
-.B x\ stop
-command is encountered; the last line of any
-.I groff intermediate output
-always contains such a command.
-.
-.
-.P
-Semantically, the
-.I body
-is page oriented.
-.
-A new page is started by a
-.BR p \~command.
-.
-Positioning, writing, and drawing commands are always done within the
-current page, so they cannot occur before the first
-.BR p \~command.
-.
-Absolute positioning (by the
-.B H
-and
-.BR V \~commands)
-is done relative to the current page, all other positioning
-is done relative to the current location within this page.
-.
-.
-.\" --------------------------------------------------------------------
-.SH "COMMAND REFERENCE"
-.\" --------------------------------------------------------------------
-.
-This section describes all
-.I intermediate output
-commands, the classical commands as well as the
-.I groff
-extensions.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Comment Command"
-.\" --------------------------------------------------------------------
-.
-.TP
-.BI # anything \[la]end_of_line\[ra]
-A comment.
-.
-Ignore any characters from the
-.BR # \~\c
-character up to the next newline character.
-.
-.P
-This command is the only possibility for commenting in the
-.I intermediate
-.IR output .
-.
-Each comment can be preceded by arbitrary
-.I syntactical
-.IR space ;
-every command can be terminated by a comment.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Simple Commands"
-.\" --------------------------------------------------------------------
-.
-The commands in this subsection have a command code consisting of a
-single character, taking a fixed number of arguments.
-.
-Most of them are commands for positioning and text writing.
-.
-These commands are smart about whitespace.
-.
-Optionally,
-.I syntactical space
-can be inserted before, after, and between the command letter and its
-arguments.
-.
-All of these commands are stackable, i.e., they can be preceded by
-other simple commands or followed by arbitrary other commands on the
-same line.
-.
-A separating
-.I syntactical space
-is only necessary when two integer arguments would clash or if the
-preceding argument ends with a string argument.
-.
-.
-.if (\n[@USE_ENV_STACK] == 1) \{\
-.command {
-Open a new environment by copying the actual device configuration data
-to the environment stack.
-.
-The current environment is setup by the device specification and
-manipulated by the setting commands.
-.
-.
-.command }
-Close the actual environment (opened by a preceding
-.BR { \~command)
-and restore the previous environment from the environment
-stack as the actual device configuration data.
-.
-\}              \" endif @USE_ENV_STACK
-.
-.
-.command C xxx \[la]white_space\[ra]
-Print a special groff character named
-.argument xxx .
-.
-The trailing
-.I syntactical space
-or
-.I line break
-is necessary to allow character names of arbitrary length.
-.
-The character is printed at the current print position; the
-character's size is read from the font file.
-.
-The print position is not changed.
-.
-.
-.command c c
-Print character\~\c
-.argument c
-at the current print position;
-the character's size is read from the font file.
-.
-The print position is not changed.
-.
-.
-.command f n
-Set font to font number\~\c
-.argument n
-(a non-negative integer).
-.
-.
-.command H n
-Move right to the absolute vertical position\~\c
-.argument n
-(a non-negative integer in basic units\~\c
-.unit u )
-relative to left edge of current page.
-.
-.
-.command h n
-Move
-.argument n
-(a non-negative integer) basic units\~\c
-.unit u
-horizontally to the right.
-.
-.I [CSTR\~#54]
-allows negative values for
-.I n
-also, but
-.I groff
-doesn't use this.
-.
-.
-.command m "color_scheme \f[R][\f[]component .\|.\|.\f[R]]\f[]"
-Set the color for text (glyphs), line drawing, and the outline of
-graphic objects using different color schemes; the analoguous command
-for the filling color of graphic objects is
-.BR DF .
-.
-The color components are specified as integer arguments between 0 and
-\n[@maxcolor].
-.
-The number of color components and their meaning vary for the
-different color schemes.
-.
-These commands are generated by the
-.I groff
-escape sequence
-.BR \*[@backslash]m .
-.
-No position changing.
-.
-These commands are a
-.I groff
-extension.
-.
-.
-.RS
-.
-.command mc "cyan magenta yellow"
-Set color using the CMY color scheme, having the 3\~color components
-cyan, magenta, and yellow.
-.
-.
-.command md
-Set color to the default color value
-(black in most cases).
-.
-No component arguments.
-.
-.
-.command mg "gray"
-Set color to the shade of gray given by the argument, an integer
-between 0 (black) and \n[@maxcolor] (white).
-.
-.
-.command mk "cyan magenta yellow black"
-Set color using the CMYK color scheme, having the 4\~color components
-cyan, magenta, yellow, and black.
-.
-.command mr "red green blue"
-Set color using the RGB color scheme, having the 3\~color components
-red, green, and blue.
-.
-.RE
-.
-.
-.command N n
-Print character with index\~\c
-.argument n
-(an integer, normally non-negative) of the current font.
-.
-The print position is not changed.
-.
-If
-.B \-T\~html
-is used, negative values are emitted also to indicate an unbreakable space
-with given width.
-.
-For example,
-.B N\~-193
-represents an unbreakable space which has a width of 193u.
-.
-This command is a
-.I groff
-extension.
-.
-.
-.command n b\ a
-Inform the device about a line break, but no positioning is done by
-this command.
-.
-In
-.I classical
-.IR troff ,
-the integer arguments
-.argument b
-and\~\c
-.argument a
-informed about the space before and after the current line to
-make the
-.I intermediate output
-more human readable without performing any action.
-.
-In
-.IR groff ,
-they are just ignored, but they must be provided for compatibility
-reasons.
-.
-.
-.command p n
-Begin a new page in the outprint.
-.
-The page number is set to\~\c
-.argument n .
-.
-This page is completely independent of pages formerly processed even
-if those have the same page number.
-.
-The vertical position on the outprint is automatically set to\~0.
-.
-All positioning, writing, and drawing is always done relative to a
-page, so a
-.BR p \~command
-must be issued before any of these commands.
-.
-.
-.command s n
-Set point size to
-.argument n
-scaled points
-(this is unit\~\c
-.unit z
-in GNU
-.BR @g@troff ).
-.
-.I Classical troff
-used the unit
-.I points
-(\c
-.unit p )
-instead; see section
-.BR COMPATIBILITY .
-.
-.
-.command t xxx \[la]white_space\[ra]
-.command+ t "xxx dummy_arg" \[la]white_space\[ra]
-Print a word, i.e., a sequence of characters
-.argument xxx
-terminated by a space character or a line break; an optional second
-integer argument is ignored (this allows the formatter to generate
-an even number of arguments).
-.
-The first character should be printed at the current position, the
-current horizontal position should then be increased by the width of
-the first character, and so on for each character.
-.
-The widths of the characters are read from the font file, scaled for the
-current point size, and rounded to a multiple of the horizontal
-resolution.
-.
-Special characters cannot be printed using this command (use the
-.B C
-command for named characters).
-.
-This command is a
-.I groff
-extension; it is only used for devices whose
-.I DESC
-file contains the
-.B tcommand
-keyword; see
-.BR groff_font (@MAN5EXT@).
-.
-.
-.command u "n xxx" \[la]white_space\[ra]
-Print word with track kerning.
-.
-This is the same as the
-.B t
-command except that after printing each character, the current
-horizontal position is increased by the sum of the width of that
-character and\~\c
-.argument n
-(an integer in
-basic units\~\c
-.unit u ).
-This command is a
-.I groff
-extension; it is only used for devices whose
-.I DESC
-file contains the
-.B tcommand
-keyword; see
-.BR groff_font (@MAN5EXT@).
-.
-.
-.command V n
-Move down to the absolute vertical position\~\c
-.argument n
-(a non-negative integer in basic units\~\c
-.unit u )
-relative to upper edge of current page.
-.
-.
-.command v n
-Move
-.argument n
-basic units\~\c
-.unit u
-down
-.RI ( n
-is a non-negative integer).
-.
-.I [CSTR\~#54]
-allows negative values for
-.I n
-also, but
-.I groff
-doesn't use this.
-.
-.
-.command w
-Informs about a paddable whitespace to increase readability.
-.
-The spacing itself must be performed explicitly by a move command.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Graphics Commands"
-.\" --------------------------------------------------------------------
-.
-Each graphics or drawing command in the
-.I intermediate output
-starts with the letter\~\c
-.B D
-followed by one or two characters that specify a subcommand; this
-is followed by a fixed or variable number of integer arguments that
-are separated by a single space character.
-.
-A
-.B D\c
-\~command
-may not be followed by another command on the same line (apart from a
-comment), so each
-.B D\c
-\~command
-is terminated by a
-.I syntactical line
-.IR break .
-.
-.
-.P
-.B @g@troff
-output follows the classical spacing rules (no space between command
-and subcommand, all arguments are preceded by a single space
-character), but the parser allows optional space between the command
-letters and makes the space before the first argument optional.

-.SS "Device Control Commands"
-.\" --------------------------------------------------------------------
-.
-Each device control command starts with the letter
-.B x
-followed by a space character (optional or arbitrary space/\:tab in
-.IR groff )
-and a subcommand letter or word; each argument (if any) must be
-preceded by a
-.I syntactical
-.IR space .
-.
-All
-.B x
-commands are terminated by a
-.IR "syntactical line break" ;
-no device control command can be followed by another command on the same
-line (except a comment).
-.
-.P
-The subcommand is basically a single letter, but to increase
-readability, it can be written as a word, i.e., an arbitrary sequence
-of characters terminated by the next tab, space, or newline character.
-.
-All characters of the subcommand word but the first are simply ignored.
-.
-For example,
-.B @g@troff
-outputs the initialization command
-.B x\ i
-as
-.B x\ init
-and the resolution command
-.B x\ r
-as
-.BR "x\ res" .
-.
-But writings like
-.B x\ i_like_groff
-and
-.B x\ roff_is_groff
-resp.\& are accepted as well to mean the same commands.
-.

-.SH "COMPATIBILITY"
-.\" --------------------------------------------------------------------
-.
-The
-.I intermediate output
-language of the 
-.I classical troff
-was first documented in
-.IR [CSTR\~#97] .
-.
-The
-.I groff intermediate output
-format is compatible with this specification except for the following
-features.
-.
-.
-.Topic
-The classical quasi device independence is not yet implemented.
-.
-.
-.Topic
-The old hardware was very different from what we use today.
-.
-So the
-.I groff
-devices are also fundamentally different from the ones in
-.I classical
-.IR troff .
-.
-For example, the classical PostScript device was called
-.I post
-and had a resolution of 720 units per inch,
-while
-.IR groff 's
-.I ps
-device has a resolution of 72000 units per inch.
-.
-Maybe, by implementing some rescaling mechanism similar to the
-classical quasi device independence, these could be integrated into
-modern
-.IR groff .
-.
-.
-.Topic
-The B-spline command
-.B D~
-is correctly handled by the
-.I intermediate output
-parser, but the drawing routines aren't implemented in some of the
-postprocessor programs.
-.
-.
-.Topic
-The argument of the commands
-.B s
-and
-.B x H
-has the implicit unit scaled point\~\c
-.unit z
-in
-.IR groff ,
-while
-.I classical troff
-had point (\c
-.unit p ).
-.
-This isn't an incompatibility, but a compatible extension, for both
-units coincide for all devices without a
-.I sizescale
-parameter, including all classical and the
-.I groff
-text devices.
-.
-The few
-.I groff
-devices with a sizescale parameter either did not exist, had a
-different name, or seem to have had a different resolution.
-.
-So conflicts with classical devices are very unlikely.

-.\" SH DESCRIPTION
-.\" --------------------------------------------------------------------
-.
-The
-.BR roff (@MAN7EXT@)
-type-setting system provides a set of macro packages suitable for
-special kinds of documents.
-.
-Each macro package stores its macros and definitions in a file called
-the package's
-.BR "tmac file" .
-The name is deduced from
-.RB ` T\c
-.IB roff MAC\c
-.IR ros '.
-.
-.P
-The tmac files are normal roff source documents, except that they
-usually contain only definitions and setup commands, but no text.
-.
-All tmac files are kept in a single or a small number of directories,
-the
-.B tmac
-directories.
-.
-.
-.\" --------------------------------------------------------------------
-.SH "GROFF MACRO PACKAGES"
-.\" --------------------------------------------------------------------
-.
-.I groff
-provides all classical macro packages, some more full packages, and
-some secondary packages for special purposes.
-.
-Note that it is not possible to use multiple primary macro packages at the
-same time; saying e.g.\&
-.
-.IP
-.Shell_cmd "groff \-m man \-m ms foo"
-.
-.P
-or
-.
-.IP
-.Shell_cmd "groff \-m man foo \-m ms bar"
-.
-.P
-will fail.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Man\~Pages"
-.\" --------------------------------------------------------------------
-.

-.B man
-This is the classical macro package for UNIX manual pages
-(man\~pages); it is quite handy and easy to use; see
-.BR groff_man (@MAN7EXT@).
-.
-.
-.TP
-.B doc
-.TP+
-.B mdoc
-An alternative macro package for man\~pages mainly used in BSD
-systems; it provides many new features, but it is not the standard for
-man\~pages; see
-.BR groff_mdoc (@MAN7EXT@).
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Full Packages"
-.\" --------------------------------------------------------------------
-.
-The packages in this section provide a complete set of macros for
-writing documents of any kind, up to whole books.
-.
-They are similar in functionality; it is a matter of taste which one
-to use.
-.
-.
-.TP
-.B me
-The classical
-.I me

-.
-.
-.TP
-.B mom
-The new
-.I mom
-macro package, only available in groff.
-.
-As this is not based on other packages, it can be freely designed.
-.
-So it is expected to become quite a nice, modern macro package.

-.\" --------------------------------------------------------------------
-.SS "Special Packages"
-.\" --------------------------------------------------------------------
-.
-The macro packages in this section are not intended for stand-alone
-usage, but can be used to add special functionality to any other
-macro package or to plain groff.
-.
-.
-.TP
-.B papersize
-This macro file is already loaded at start-up by
-.B @g@troff
-so it isn't necessary to call it explicitly.
-.
-It provides an interface to set the paper size on the command line with
-the option \f[B]\%\-dpaper=\f[]\f[I]size\f[].
-.
-Possible values for
-.I size
-are the same as the predefined
-.B papersize
-values in the DESC file (only lowercase; see
-.BR groff_font (@MAN5EXT@)
-for more) except
-.BR a7 - d7 .
-.
-An appended
-.B l
-(ell) character denotes landscape orientation.
-.
-Examples:
-.BR a4 ,
-.BR c3l ,
-.BR letterl .
-.
-.IP
-Most output drivers need additional command line switches
-.B \-p
-and
-.B \-l
-to override the default paper length and orientation as set in the driver
-specific DESC file.
-.
-For example, use the following for PS output on A4 paper in landscape
-orientation:
-.
-.IP
-.Shell_cmd "groff \-Tps \-dpaper=a4l \-P\-pa4 \-P\-l \-ms foo.ms > foo.ps"
-.
-.
-.TP
-.B pic
-This file provides proper definitions for the macros
-.B PS
-and
-.BR PE ,
-needed for the
-.BR @g@pic (@MAN1EXT@)
-preprocessor.
-.
-They will center each picture.
-.
-Use it only if your macro package doesn't provide proper definitions
-for those two macros (actually, most of them already have).
-.
-.
-.TP
-.B pspic
-A single macro is provided in this file,
-.BR PSPIC ,
-to include a PostScript graphic in a document.
-.
-It makes only sense for output devices which support inclusion of PS
-images:
-.BR \-Tps ,
-.BR \-Tdvi ,
-and
-.BR \-Thtml ;
-the file is then loaded automatically.
-.
-Syntax:
-.RS
-.IP
-\&\fB.PSPIC\fP [\fB\-L\fP|\fB-R\fP|\fB\-I\fP \fIn\fP]\ \fI\|file\fP [\fIwidth\fP [\fIheight\fP]]
-.RE
-.
-.IP
-.I file
-is the name of the file containing the illustration;
-.I width
-and
-.I height
-give the desired width and height of the graphic.
-.
-The
-.I width
-and
-.I height
-arguments may have scaling indicators attached;
-the default scaling indicator is\~\c
-.BR i .
-.
-This macro will scale the graphic uniformly
-in the x and y\~directions so that it is no more than
-.I width
-wide
-and
-.I height
-high.
-.
-By default, the graphic will be horizontally centered.
-.
-The
-.BI \-L
-and
-.BI \-R
-options cause the graphic to be left-aligned and right-aligned,
-respectively.
-.
-The
-.B \-I
-option causes the graphic to be indented by\~\c
-.I n
-(default scaling indicator is\~\c
-.BR m ).
-.
-.
-.TP
-.B trace
-Use this for tracing macro calls.
-.
-It is only useful for debugging.
-.
-See
-.BR groff_trace (@MAN7EXT@) .
-.
-.
-.TP
-.B tty-char
-Overrides the definition of standard troff characters and some groff
-characters for tty devices.
-.
-The optical appearance is intentionally inferior compared to that of
-normal tty formatting to allow processing with critical equipment.
-.
-.
-.TP
-.B www
-Additions of elements known from the html format, as being used in the
-internet (World Wide Web) pages; this includes URL links and mail
-addresses; see
-.BR groff_www (@MAN7EXT@).
-.
-.
-.\" --------------------------------------------------------------------
-.SH NAMING
-.\" --------------------------------------------------------------------
-.
-In classical roff systems, there was a funny naming scheme for macro
-packages, due to a simplistic design in option parsing.
-.
-Macro packages were always included by option
-.option -m;
-when this option was directly followed by its argument without an
-intervening space, this looked like a long option preceded by a single
-minus \[em] a sensation in the computer stone age.
-.
-To make this optically working for macro package names, all classical
-macro packages choose a name that started with the letter
-.'char m ,
-which was omitted in the naming of the macro file.
-.
-.
-.P
-For example, the macro package for the man pages was called
-.IR man ,
-while its macro file
-.IR tmac.an .
-So it could be activated by the argument
-.I an
-to option
-.option -m ,
-or
-.option -man
-for short.
-.
-.
-.P
-For similar reasons, macro packages that did not start with an
-.'char m
-had a leading
-.'char m
-added in the documentation and in talking; for example, the package
-corresponding to
-.I tmac.doc
-was called
-.I mdoc
-in the documentation, although a more suitable name would be
-.IR doc .
-For, when omitting the space between the option and its argument, the
-command line option for activating this package reads
-.option "-mdoc" .
-.
-.
-.P
-To cope with all situations, actual versions of
-.BR groff (@MAN1EXT@)
-are smart about both naming schemes by providing two macro files
-for the inflicted macro packages; one with a leading
-.'char m ,
-the other one without it.
-.
-So in
-.IR groff ,
-the
-.I man
-macro package may be specified as on of the following four methods:
-.
-.IP
-.Shell_cmd "groff\~\-m\~man"
-.Shell_cmd "groff\~\-man"
-.Shell_cmd "groff\~\-mman"
-.Shell_cmd "groff\~\-m\~an"
-.
-.
-.P
-Recent packages that do not start with
-.'char m
-do not use an additional
-.'char m
-in the documentation.
-.
-For example, the
-.I www
-macro package may be specified only as one of the two methods:
-.
-.IP
-.Shell_cmd "groff\~\-m\~www"
-.Shell_cmd "groff\~\-mwww"
-.
-.
-.P
-Obviously, variants like
-.I -mmwww
-would not make much sense.
-.
-.
-.P
-A second strange feature of classical troff was to name macro files
-according to
-.BIR tmac. name .
-In modern operating systems, the type of a file is specified as
-postfix, the file name extension.
-.
-Again, groff copes with this situation by searching both
-.IB anything .tmac
-and
-.BI tmac. anything
-if only
-.I anything
-is specified.
-.
-.
-.P
-The easiest way to find out which macro packages are available on a
-system is to check the man\~page
-.BR groff (@MAN1EXT@),
-or the contents of the
-.I tmac
-directories.
-.
-.
-.P
-In
-.IR groff ,
-most macro packages are described in\~man pages called
-.BR groff_\f[I]name\f[] (@MAN7EXT@),
-with a leading
-.'char m
-for the classical packages.
-.
-.
-.\" --------------------------------------------------------------------
-.SH INCLUSION
-.\" --------------------------------------------------------------------
-.
-There are several ways to use a macro package in a document.
-.
-The classical way is to specify the troff/groff option
-.option \-m
-.argument name
-at run-time; this makes the contents of the macro package
-.I name
-available.
-.
-In groff, the file
-.IB name .tmac
-is searched within the tmac path; if not found,
-.BI tmac. name
-will be searched for instead.
-.
-.
-.P
-Alternatively, it is also possible to include a macro file by adding
-the request
-.request so
-.I filename
-into the document; the argument must be the full file name of an
-existing file, possibly with the directory where it is kept.
-.
-In groff, this was improved by the similar request
-.request mso
-.IR package ,
-which added searching in the tmac path, just like option
-.option -m
-does.
-.
-.
-.P
-Note that in order to resolve the
-.request so
-and
-.request mso
-requests, the roff preprocessor
-.BR soelim (@MAN1EXT@)
-must be called if the files to be included need preprocessing.
-.
-This can be done either directly by a pipeline on the command line or
-by using the troff/groff option
-.option \-s .
-.
-.I man
-calls soelim automatically.
-.
-.
-.P
-For example, suppose a macro file is stored as
-.I @MACRODIR@/macros.tmac
-and is used in some document called
-.IR docu.roff .
-.
-.
-.P
-At run-time, the formatter call for this is
-.
-.IP
-.Shell_cmd "groff\~\-m\~" "macrofile\~document.roff"
-.
-.
-.P
-To include the macro file directly in the document either
-.
-.IP
-.Example
-.  Text .mso macrofile.tmac
-./Example
-.
-.P
-is used or
-.
-.IP
-.Example
-.  Text .so @MACRODIR@/macros.tmac
-./Example
-.
-.
-.P
-In both cases, the formatter is called with
-.IP
-.Shell_cmd "groff\~\-s\~" docu.roff
-.
-.
-.P
-If you want to write your own groff macro file, call it
-.IB whatever .tmac
-and put it in some directory of the tmac path, see section
-.BR FILES .
-Then documents can include it with the
-.request mso
-request or the option
-.option -m .

-.SH CONVENTION
-.\" --------------------------------------------------------------------
-.
-.\" This section does not fit into the framework of this document.
-.
-There is a convention that is supported by many modern roff
-type-setters and
-.BR man (1)
-programs, the
-.I preprocessor word
-described in the following.
-.
-.P
-If the first line in a document is a comment, the first word (after the
-comment characters and a blank) constitutes the
-.B preprocessor
-.BR word .
-That means that the letters of this word are interpreted as
-abbreviations for those preprocessor commands that should be run
-when formatting the document.
-.
-Mostly, only the letters corresponding to the options for the
-preprocessors are recognized,
-.'char e
-(for
-.BR eqn ),
-.\" 'char G ,
-.\" 'char g ,
-.'char p ,
-(for
-.BR pic ),
-.'char R
-(for
-.BR refer ),
-.'char s
-(for
-.BR soelim ),
-and
-.'char t
-(for
-.BR tbl ).
-(see
-.BR roff (@MAN7EXT@)).
-.
-.
-.P
-Besides being a good reminder for the user, some formatters (like the
-.BR man (1)
-program) are even able to automatically start the preprocessors
-specified in the preprocessor word, but do not bet on this.
-.
-.
-.P
-The
-.I man
-program handles some preprocessors automatically, such that in
-man\~pages only the following characters should be used:
-.'char e ,
-.'char p ,
-and
-.'char t .
-.
-.
-..
-.\" --------------------------------------------------------------------
-.SH "WRITING MACROS"
-.\" --------------------------------------------------------------------
-.
-A
-.BR roff (@MAN7EXT@)
-document is a text file that is enriched by predefined formatting
-constructs, such as requests, escape sequences, strings, numeric
-registers, and macros from a macro package.
-.
-These elements are described in
-.BR roff (@MAN7EXT@).
-.
-.
-.P
-To give a document a personal style, it is most useful to extend the
-existing elements by defining some macros for repeating tasks; the best
-place for this is near the beginning of the document or in a separate
-file.
-.
-.
-.P
-Macros without arguments are just like strings.
-.
-But the full power of macros reveals when arguments are passed with a
-macro call.
-.
-Within the macro definition, the arguments are available as the escape
-sequences
-.BR $1 ,
-\*[Ellipsis],
-.BR $9 ,
-.BR $[ \*[Ellipsis] ] ,
-.BR $* ,
-and
-.BR $@ ,
-the name under which the macro was called is in
-.BR $0 ,
-and the number of arguments is in register
-.BR \n[.$] ;
-see
-.BR groff (@MAN7EXT@).

-This is comparable to the C\~preprocessing phase during the development
-of a program written in the C\~language.
-.
-.
-.P
-In this phase, groff interprets all backslashes; that means that all
-escape sequences in the macro body are interpreted and replaced by
-their value.
-.
-For constant expression, this is wanted, but strings and registers
-that might change between calls of the macro must be protected from
-being evaluated.
-.
-This is most easily done by doubling the backslash that introduces the
-escape sequence.
-.
-This doubling is most important for the positional parameters.
-.
-For example, to print information on the arguments that were passed to
-the macro to the terminal, define a macro named `.print_args',
-say.
-.
-.
-.P
-.ds @1 \[rs]f[I]\[rs]\[rs]$0\[rs]f[]\"
-.ds @2 arguments:\"
-.Example
-.  Text .ds midpart was called with
-.  Text .de print_args
-.  Text .\~\~tm\~\*[@1]\~\[rs]\[rs]*[midpart]\~\[rs]\[rs]n[.$]\~\*[@2]
-.  Text .\~\~tm\~\[rs]\[rs]$*
-.  Text ..
-./Example
-.rm @1
-.rm @2
-.
-.
-.P
-When calling this macro by
-.
-.P
-.Example
-.  Text .print_args arg1 arg2
-./Example
-.
-.P
-the following text is printed to the terminal:
-.
-.P
-.Example
-.  Text \f[CI]print_args\f[] was called with the following 2 arguments:
-arg1 arg2
-./Example
-.
-.
-.P
-Let's analyze each backslash in the macro definition.
-.
-As the positional parameters and the number of arguments will change
-with each call of the macro their leading backslash must be doubled,
-which results in
-.I \[rs]\[rs]$*
-and
-.IR \[rs]\[rs][.$] .
-The same applies to the macro name because it could be called with an
-alias name, so
-.IR \[rs]\[rs]$0 .
-.
-.
-.P
-On the other hand,
-.I midpart
-is a constant string, it will not change, so no doubling for
-.IR \[rs]*[midpart] .
-The
-.I \[rs]f
-escape sequences are predefined groff elements for setting the font
-within the text.
-.
-Of course, this behavior will not change, so no doubling with
-.I \[rs]f[I]
-and
-.IR \[rs]f[] .
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Draft Mode"
-.\" --------------------------------------------------------------------
-.
-Writing groff macros is easy when the escaping mechanism is temporarily
-disabled.
-.
-In groff, this is done by enclosing the macro definition(s) into a
-pair of
-.B .eo
-and
-.B .ec
-requests.
-.
-Then the body in the macro definition is just like a normal part of
-the document \[em] text enhanced by calls of requests, macros,
-strings, registers, etc.
-.
-For example, the code above can be written in a simpler way by
-.
-.
-.P
-.ds @1 \[rs]f[I]\[rs]$0\[rs]f[]\"
-.ds @2 arguments:\"
-.Example
-.  Text .eo
-.  Text .ds midpart was called with
-.  Text .de print_args
-.  Text .\~\~tm\~\*[@1]\~\[rs]*[midpart]\~\[rs]n[.$]\~\*[@2]
-.  Text .\~\~tm\~\[rs]$*
-.  Text ..
-.  Text .ec
-./Example
-.rm @1
-.rm @2
-.
-.
-.P
-Unfortunately, draft mode cannot be used universally.
-.
-Although it is good enough for defining normal macros, draft mode
-will fail with advanced applications, such as indirectly defined
-strings, registers, etc.
-.
-An optimal way is to define and test all macros in draft mode and then
-do the backslash doubling as a final step; do not forget to remove the
-.I .eo
-request.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Tips for Macro Definitions"
-.\" --------------------------------------------------------------------
-.
-.Topic
-Start every line with a dot, for example, by using the groff request
-.B .nop
-for text lines, or write your own macro that handles also text lines
-with a leading dot.
-.
-.IP
-.Example
-.  Text .de Text
-.  Text .\~\~if (\[rs]\[rs]n[.$] == 0)\~\[rs]
-.  Text .\~\~\~\~return
-.  Text .\~nop\~\[rs])\[rs]\[rs]$*[rs]\)
-.  Text ..
-./Example
-.
-.Topic
-Write a comment macro that works both for copy-in and draft mode; for
-as escaping is off in draft mode, trouble might occur when normal
-comments are used.
-.
-For example, the following macro just ignores its arguments, so it
-acts like a comment line:
-.
-.IP
-.Example
-.  Text .de\~c
-.  Text ..
-.  Text .c\~This\~is\~like\~a\~comment\~line.
-./Example
-.
-.Topic
-In long macro definitions, make ample use of comment lines or empty
-lines for a better structuring.
-.
-.Topic
-To increase readability, use groff's indentation facility for requests
-and macro calls (arbitrary whitespace after the leading dot).
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Diversions"
-.\" --------------------------------------------------------------------
-.
-Diversions can be used to realize quite advanced programming
-constructs.
-.
-They are comparable to pointers to large data structures in the
-C\~programming language, but their usage is quite different.
-.
-.
-.P
-In their simplest form, diversions are multi-line strings, but
-they get their power when diversions are used dynamically within macros.
-.
-The information stored in a diversion can be retrieved by calling the
-diversion just like a macro.
-.
-.
-.P
-Most of the problems arising with diversions can be avoided if you are
-conscious about the fact that diversions always deal with complete
-lines.
-.
-If diversions are used when the line buffer has not been flashed,
-strange results are produced; not knowing this, many people get
-desperate about diversions.
-.
-To ensure that a diversion works, line breaks should be added at the
-right places.
-.
-To be on the secure side, enclose everything that has to do with
-diversions into a pair of line breaks; for example, by amply using
-.B .br
-requests.
-.
-This rule should be applied to diversion definition, both inside and
-outside, and to all calls of diversions.
-.
-This is a bit of overkill, but it works nicely.
-.
-.
-.P
-[If you really need diversions which should ignore the current partial
-line, use environments to save the current partial line and/\:or use the
-.B .box
-request.]
-.
-.
-.P
-The most powerful feature using diversions is to start a diversion
-within a macro definition and end it within another macro.
-.
-Then everything between each call of this macro pair is stored within
-the diversion and can be manipulated from within the macros.
-.
-.

-.SH NAME
-roff \- concepts and history of roff typesetting
-.
-.
-.\" --------------------------------------------------------------------
-.SH DESCRIPTION
-.\" --------------------------------------------------------------------
-.
-.I roff
-is the general name for a set of type-setting programs, known under
-names like
-.IR troff ,
-.IR nroff ,
-.IR ditroff ,
-.IR groff ,
-etc.
-.
-A roff type-setting system consists of an extensible text formatting
-language and a set of programs for printing and converting to other
-text formats.
-.
-Traditionally, it is the main text processing system of Unix; every
-Unix-like operating system still distributes a roff system as a core
-package.
-.
-.P
-The most common roff system today is the free software implementation
-.IR "GNU roff",
-.BR groff (@MAN1EXT@).
-.
-The pre-groff implementations are referred to as
-.I classical
-(dating back as long as 1973).
-.
-.I groff
-implements the look-and-feel and functionality of its classical
-ancestors, but has many extensions.
-.
-As
-.I groff
-is the only roff system that is available for every (or almost every)
-computer system it is the de-facto roff standard today.
-.
-.P
-In some ancient Unix systems, there was a binary called
-.B roff
-that implemented the even more ancient
-.B runoff
-of the
-.I Multics
-operating system, cf. section
-.BR HISTORY .
-The functionality of this program was very restricted even in
-comparison to ancient troff; it is not supported any longer.
-.
-Consequently, in this document, the term
-.I roff
-always refers to the general meaning of
-.IR "roff system" ,
-not to the ancient roff binary.
-.
-.P
-In spite of its age, roff is in wide use today, for example, the manual
-pages on UNIX systems
-.RI ( man\~pages\/ ),
-many software books, system documentation, standards, and corporate
-documents are written in roff.
-.
-The roff output for text devices is still unmatched, and its graphical
-output has the same quality as other free type-setting programs and is
-better than some of the commercial systems.
-.
-.P
-The most popular application of roff is the concept of
-.I manual pages
-or shortly
-.IR "man pages" ;
-this is the standard documentation system on many operating systems.
-.
-.P
-This document describes the historical facts around the development
-of the
-.IR "roff system" ;
-some usage aspects common to all roff versions, details on the roff
-pipeline, which is usually hidden behind front-ends like
-.BR groff (@MAN1EXT@);
-an general overview of the formatting language; some tips for editing
-roff files; and many pointers to further readings.
-.
-.
-.\" --------------------------------------------------------------------
-.SH "HISTORY"
-.\" --------------------------------------------------------------------
-.
-The
-.I roff
-text processing system has a very long history, dating back to the
-1960s.
-.
-The roff system itself is intimately connected to the Unix operating
-system, but its roots go back to the earlier operating systems CTSS
-and Multics.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "The Predecessor runoff"
-.\" --------------------------------------------------------------------
-.
-.P
-The evolution of
-.I roff
-is intimately related to the history of the operating systems.
-.
-Its predecessor
-.B runoff
-was written by
-.I Jerry Saltzer
-on the
-.I CTSS
-operating system
-.RI ( "Compatible Time Sharing System" )
-as early as 1961.
-.
-When CTSS was further developed into the operating system
-.URL http://\:www.multicians.org "Multics" ,
-the famous predecessor of Unix from 1963,
-.I runoff
-became the main format for documentation and text processing.
-.
-Both operating systems could only be run on very expensive computers
-at that time, so they were mostly used in research and for official
-and military tasks.
-.
-.P
-The possibilities of the
-.I runoff
-language were quite limited as compared to modern roff.
-.
-Only text output was possible in the 1960s.
-.
-This could be implemented by a set of requests of length\~2, many of
-which are still identically used in roff.
-.
-The language was modelled according to the habits of typesetting in
-the pre-computer age, where lines starting with a dot were used in
-manuscripts to denote formatting requests to the person who would
-perform the typesetting manually later on.
-.
-.P
-The runoff program was written in the
-.I PL/1
-language first, later on in
-.IR BCPL ,
-the grandmother of the
-.IR C \~\c
-programming language.
-.
-In the Multics operating system, the help system was handled by
-runoff, similar to roff's task to manage the Unix manual pages.
-.
-There are still documents written in the runoff language; for examples
-see Saltzer's home page, cf. section
-.BR "SEE ALSO" .
-.
-.
-.\" --------------------------------------------------------------------
-.SS "The Classical nroff/troff System"
-.\" --------------------------------------------------------------------
-.
-In the 1970s, the Multics off-spring
-.I Unix
-became more and more popular because it could be run on affordable
-machines and was easily available for universities at that time.
-.
-At MIT (the Massachusetts Institute of Technology), there was a need to
-drive the Wang
-.I Graphic Systems CAT
-typesetter, a graphical output device from a PDP-11 computer running
-Unix.
-.
-As runoff was too limited for this task it was further developed into
-a more powerful text formatting system by
-.IR "Josef F. Osanna" ,
-a main developer of the Multics operating system and programmer of
-several runoff ports.
-.
-.P
-The name
-.I runoff
-was shortened to
-.IR roff .
-The greatly enlarged language of Osanna's concept included already all
-elements of a full
-.IR "roff system" .
-.
-All modern roff systems try to implement compatibility to this system.
-.
-So Joe Osanna can be called the father of all roff systems.
-.
-.P
-This first
-.I roff system
-had three formatter programs.
-.
-.TP
-.B troff
-.RI ( "typesetter roff\/" )
-generated a graphical output for the
-.I CAT
-typesetter as its only device.
-.
-.TP
-.B nroff
-produced text output suitable for terminals and line printers.
-.
-.TP
-.B roff
-was the reimplementation of the former runoff program with its limited
-features; this program was abandoned in later versions.
-.
-Today, the name
-.I roff
-is used to refer to a troff/\:nroff sytem as a whole.
-.
-.P
-Osanna first version was written in the PDP-11 assembly language and
-released in 1973.
-.
-.I Brian Kernighan
-joined the
-.I roff
-development by rewriting it in the C\~programming language.
-.
-The C\~version was released in 1975.
-.
-.P
-The syntax of the formatting language of the
-.BR nroff / troff
-programs was documented in the famous
-.IR "Troff User's Manual [CSTR\~#54]" ,
-first published in 1976, with further revisions up to 1992 by Brian
-Kernighan.
-.
-This document is the specification of the
-.IR "classical troff" .
-All later
-.I roff
-systems tried to establish compatibility with this specification.
-.
-.P
-After Osanna had died in 1977 by a heart-attack at the age of about\~50,
-Kernighan went on with developing troff.
-.
-The next milestone was to equip troff with a general interface to
-support more devices, the intermediate output format and the
-postprocessor system.
-.
-This completed the structure of a
-.I "roff system"
-as it is still in use today; see section
-.BR "USING ROFF" .
-.
-In 1979, these novelties were described in the paper
-.IR "[CSTR\~#97]" .
-This new troff version is the basis for all existing newer troff
-systems, including
-.IR groff .
-.
-On some systems, this
-.I device independent troff
-got a binary of its own, called
-.BR ditroff (@MAN7EXT@).
-.
-All modern
-.B troff
-programs already provide the full ditroff capabilities automatically.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Commercialization"
-.\" --------------------------------------------------------------------
-.
-A major degradation occurred when the easily available Unix\~7
-operating system was commercialized.
-.
-A whole bunch of divergent operating systems emerged, fighting each
-other with incompatibilities in their extensions.
-.
-Luckily, the incompatibilities did not fight the original troff.
-.
-All of the different commercial roff systems made heavy use of
-Osanna/\:Kernighan's open source code and documentation, but sold them
-as \[lq]their\[rq] system \[em] with only minor additions.
-.
-.P
-The source code of both the ancient Unix and classical troff weren't
-available for two decades.
-.
-Fortunately, Caldera bought SCO UNIX in 2001.
-.
-In the following, Caldera made the ancient source code accessible
-on-line for non-commercial use, cf. section
-.BR "SEE ALSO" .
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Free roff"
-.\" --------------------------------------------------------------------
-.
-None of the commercial roff systems could attain the status of a
-successor for the general roff development.
-.
-Everyone was only interested in their own stuff.
-.
-This led to a steep downfall of the once excellent
-Unix operating system during the 1980s.
-.
-.P
-As a counter-measure to the galopping commercialization, AT&T Bell
-Labs tried to launch a rescue project with their
-.I Plan\~9
-operating system.
-.
-It is freely available for non-commercial use, even the source code,
-but has a proprietary license that impedes the free development.
-.
-This concept is outdated, so Plan\~9 was not accepted as a platform to
-bundle the main-stream development.
-.
-.P
-The only remedy came from the emerging free operatings systems
-(386BSD, GNU/\:Linux, etc.) and software projects during the 1980s and
-1990s.
-.
-These implemented the ancient Unix features and many extensions, such
-that the old experience is not lost.
-.
-In the 21st century, Unix-like systems are again a major factor in
-computer industry \[em] thanks to free software.
-.
-.P
-The most important free roff project was the GNU port of troff,
-created by James Clark and put under the
-.URL http://\:www.gnu.org/\:copyleft "GNU Public License" .
-.
-It was called
-.I groff
-.RI ( "GNU roff" ).
-See
-.BR groff (@MAN1EXT@)
-for an overview.
-.
-.P
-The groff system is still actively developed.
-.
-It is compatible to the classical troff, but many extensions were
-added.
-.
-It is the first roff system that is available on almost all operating
-systems \[em] and it is free.
-.
-This makes groff the de-facto roff standard today.
-.
-.
-.\" --------------------------------------------------------------------
-.SH "USING ROFF"
-.\" --------------------------------------------------------------------
-.
-Most people won't even notice that they are actually using roff.
-.
-When you read a system manual page (man page) roff is working in the
-background.
-.
-Roff documents can be viewed with a native viewer called
-.BR \%xditview (1x),
-a standard program of the X window distribution, see
-.BR X (7x).
-.
-But using roff explicitly isn't difficult either.
-.
-.P
-Some roff implementations provide wrapper programs that make it easy
-to use the roff system on the shell command line.
-.
-For example, the GNU roff implementation
-.BR groff (@MAN1EXT@)
-provides command line options to avoid the long command pipes of
-classical troff; a program
-.BR grog (@MAN1EXT@)
-tries to guess from the document which arguments should be used for a
-run of groff; people who do not like specifying command line options
-should try the
-.BR groffer (@MAN1EXT@)
-program for graphically displaying groff files and man pages.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "The roff Pipe"
-.\" --------------------------------------------------------------------
-.
-Each roff system consists of preprocessors, roff formatter programs,
-and a set of device postprocessors.
-.
-This concept makes heavy use of the
-.I piping
-mechanism, that is, a series of programs is called one after the other,
-where the output of each program in the queue is taken as the input
-for the next program.

-The preprocessors generate roff code that is fed into a roff formatter
-(e.g. troff), which in turn generates

-.
-.P
-All of these parts use programming languages of their own; each
-language is totally unrelated to the other parts.
-.
-Moreover, roff macro packages that were tailored for special purposes
-can be included.
-.
-.P
-Most roff documents use the macros of some package, intermixed with
-code for one or more preprocessors, spiced with some elements from the
-plain roff language.

-The full power of the roff formatting language is seldom needed by
-users; only programmers of macro packages need to know about the gory

-.SS "Preprocessors"
-.\" --------------------------------------------------------------------
-.
-A roff preprocessor is any program that generates output that
-syntactically obeys the rules of the roff formatting language.
-.
-Each preprocessor defines a language of its own that is translated
-into roff code when run through the preprocessor program.
-.
-Parts written in these languages may be included within a roff
-document; they are identified by special roff requests or macros.
-.
-Each document that is enhanced by preprocessor code must be run
-through all corresponding preprocessors before it is fed into the
-actual roff formatter program, for the formatter just ignores all
-alien code.
-.
-The preprocessor programs extract and transform only the document
-parts that are determined for them.
-.
-.P
-There are a lot of free and commercial roff preprocessors.
-.
-Some of them aren't available on each system, but there is a small
-set of preprocessors that are considered as an integral part of each
-roff system.

-.SS "Formatter Programs"
-.\" --------------------------------------------------------------------
-.
-A
-.I roff formatter
-is a program that parses documents written in the roff formatting
-language or uses some of the roff macro packages.
-.
-It generates
-.IR "intermediate output" ,
-which is intended to be fed into a single device postprocessor that
-must be specified by a command-line option to the formatter program.
-.
-The documents must have been run through all necessary preprocessors
-before.
-.
-.P
-The output produced by a roff formatter is represented in yet another
-language, the
-.IR "intermediate output format"
-or
-.IR "troff output" .
-This language was first specified in
-.IR "[CSTR\~#97]" ;
-its GNU extension is documented in
-.BR groff_out (@MAN5EXT@).
-.
-The intermediate output language is a kind of assembly language
-compared to the high-level roff language.
-.
-The generated intermediate output is optimized for a special device,
-but the language is the same for every device.
-.
-.P
-The roff formatter is the heart of the roff system.
-.
-The traditional roff had two formatters,
-.B nroff
-for text devices and
-.B troff
-for graphical devices.
-.
-.P
-Often, the name
-.I troff
-is used as a general term to refer to both formatters.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Devices and Postprocessors"
-.\" --------------------------------------------------------------------
-.
-Devices are hardware interfaces like printers, text or graphical
-terminals, etc., or software interfaces such as a conversion into a
-different text or graphical format.
-.
-.P
-A roff postprocessor is a program that transforms troff output into a
-form suitable for a special device.
-.
-The roff postprocessors are like device drivers for the output target.
-.
-.P
-For each device there is a postprocessor program that fits the device
-optimally.
-.
-The postprocessor parses the generated intermediate output and
-generates device-specific code that is sent directly to the device.
-.
-.P
-The names of the devices and the postprocessor programs are not fixed
-because they greatly depend on the software and hardware abilities of
-the actual computer.
-.
-For example, the classical devices mentioned in
-.I [CSTR\~#54]
-have greatly changed since the classical times.
-.
-The old hardware doesn't exist any longer and the old graphical
-conversions were quite imprecise when compared to their modern
-counterparts.
-.
-.P
-For example, the Postscript device
-.I post
-in classical troff had a resolution
-of 720, while groff's
-.I ps
-device has 72000, a refinement of factor 100.
-.
-.P
-Today the operating systems provide device drivers for most
-printer-like hardware, so it isn't necessary to write a special
-hardware postprocessor for each printer.
-.
-.
-.\" --------------------------------------------------------------------
-.SH "ROFF PROGRAMMING"
-.\" --------------------------------------------------------------------
-.
-Documents using roff are normal text files decorated by roff
-formatting elements.
-.
-The roff formatting language is quite powerful; it is almost a full
-programming language and provides elements to enlarge the language.
-.
-With these, it became possible to develop macro packages that are
-tailored for special applications.
-.
-Such macro packages are much handier than plain roff.
-.
-So most people will choose a macro package without worrying about the
-internals of the roff language.
-.
-.
-.\" --------------------------------------------------------------------
-.SS "Macro Packages"
-.\" --------------------------------------------------------------------
-.
-Macro packages are collections of macros that are suitable to format a
-special kind of documents in a convenient way.
-.
-This greatly eases the usage of roff.
-.
-The macro definitions of a package are kept in a file called
-.IB name .tmac
-(classically
-.BI tmac. name\c
-).
-.
-All tmac files are stored in one or more directories at standardized
-positions.
-.
-Details on the naming of macro packages and their placement is found
-in
-.BR groff_tmac (@MAN5EXT@).
-.
-.P
-A macro package that is to be used in a document can be announced to
-the formatter by the command line option
-.ShortOpt m ,
-see
-.BR troff (@MAN1EXT@),
-or it can be specified within a document using the file inclusion
-requests of the roff language, see
-.BR groff (@MAN7EXT@).
-.
-.P
-Famous classical macro packages are
-.I man
-for traditional man pages,
-.I mdoc
-for BSD-style manual pages;
-the macro sets for books, articles, and letters are
-.I me
-(probably from the first name of its creator
-.I Eric
-Allman),
-.I ms
-(from
-.IR "Manuscript Macros\/" ),
-and
-.I mm
-(from
-.IR "Memorandum Macros\/" ).
-.
-.
-.\" --------------------------------------------------------------------
-.SS "The roff Formatting Language"
-.\" --------------------------------------------------------------------
-.
-The classical roff formatting language is documented in the
-.I Troff User's Manual
-.IR "[CSTR\~#54]" .
-.
-The roff language is a full programming language providing requests,
-definition of macros, escape sequences, string variables, number or
-size registers, and flow controls.
-.
-.P
-.I Requests
-are the predefined basic formatting commands similar to the commands
-at the shell prompt.
-.
-The user can define request-like elements using predefined roff
-elements.
-.
-These are then called
-.IR macros .
-.
-A document writer will not note any difference in usage for requests
-or macros; both are written on a line on their own starting with a dot.
-.
-.P
-.I Escape sequences
-are roff elements starting with a backslash
-.QuotedChar \[rs] .
-They can be inserted anywhere, also in the midst of text in a line.
-.
-They are used to implement various features, including the insertion of
-non-ASCII characters with
-.Esc ( ,
-font changes with
-.Esc f ,
-in-line comments with
-.Esc \[dq] ,
-the escaping of special control characters like
-.Esc \[rs] ,
-and many other features.
-.
-.P
-.I Strings
-are variables that can store a string.
-.
-A string is stored by the
-.B .ds
-request.
-.
-The stored string can be retrieved later by the
-.B \[rs]*
-escape sequence.
-.
-.P
-.I Registers
-store numbers and sizes.
-.
-A register can be set with the request
-.B .nr
-and its value can be retrieved by the escape sequence
-.BR "\[rs]n" .
-.
-.
-.\" --------------------------------------------------------------------
-.SH "FILE NAME EXTENSIONS"
-.\" --------------------------------------------------------------------
-.
-Manual pages (man pages) take the section number as a file name
-extension, e.g., the filename for this document is
-.IR roff.7 ,
-i.e., it is kept in section\~7
-of the man pages.
-.
-.P
-The classical macro packages take the package name as an extension, e.g.
-.IB file. me
-for a document using the
-.I me
-macro package,
-.IB file. mm
-for
-.IR mm ,
-.IB file. ms
-for
-.IR ms ,
-.IB file. pic
-for
-.I pic
-files,
-etc.
-.
-.P
-But there is no general naming scheme for roff documents, though
-.IB file. tr
-for
-.I troff file
-is seen now and then.
-.
-Maybe there should be a standardization for the filename extensions of
-roff files.
-.
-.P
-File name extensions can be very handy in conjunction with the
-.BR less (1)
-pager.
-.
-It provides the possibility to feed all input into a command-line pipe
-that is specified in the shell environment variable
-.BR LESSOPEN .
-This process is not well documented, so here an example:
-.
-.CodeSkip
-.ShellCommand LESSOPEN='|lesspipe %s'
-.CodeSkip
-.
-where
-.B lesspipe
-is either a system supplied command or a shell script of your own.
-.
-.
-.\" --------------------------------------------------------------------
-.SH "EDITING ROFF"
-.\" --------------------------------------------------------------------
-.
-The best program for editing a roff document is Emacs (or Xemacs), see
-.BR emacs (1).
-It provides an
-.I nroff
-mode that is suitable for all kinds of roff dialects.
-.
-This mode can be activated by the following methods.
-.
-.P
-When editing a file within Emacs the mode can be changed by typing
-.RI ` "M-x nroff-mode" ',
-where
-.B M-x
-means to hold down the
-.B Meta
-key (or
-.BR Alt )
-and hitting the
-.BR x\~ key
-at the same time.
-.
-.P
-But it is also possible to have the mode automatically selected when
-the file is loaded into the editor.
-.
-.Topic
-The most general method is to include the following 3 comment lines at
-the end of the file.
-.
-.CodeSkip
-.nf
-.B \*[Comment] Local Variables:
-.B \*[Comment] mode: nroff
-.B \*[Comment] End:
-.fi
-.
-.Topic
-There is a set of file name extensions, e.g. the man pages that
-trigger the automatic activation of the nroff mode.
-.
-.Topic
-Theoretically, it is possible to write the sequence
-.CodeSkip
-.B \*[Comment] \%-*-\ nroff\ -*-
-.CodeSkip
-as the first line of a file to have it started in nroff mode when
-loaded.
-.
-Unfortunately, some applications such as the
-.B man
-program are confused by this; so this is deprecated.
-.
-.P
-All roff formatters provide automated line breaks and horizontal and
-vertical spacing.
-.
-In order to not disturb this, the following tips can be helpful.
-.
-.Topic
-Never include empty or blank lines in a roff document.
-.
-Instead, use the empty request (a line consisting of a dot only) or a
-line comment
-.B \*[Comment]
-if a structuring element is needed.
-.
-.Topic
-Never start a line with whitespace because this can lead to
-unexpected behavior.
-.
-Indented paragraphs can be constructed in a controlled way by roff
-requests.
-.
-.Topic
-Start each sentence on a line of its own, for the spacing after a dot
-is handled differently depending on whether it terminates an
-abbreviation or a sentence.
-.
-To distinguish both cases, do a line break after each sentence.
-.
-.Topic
-To additionally use the auto-fill mode in Emacs, it is best to insert
-an empty roff request (a line consisting of a dot only) after each
-sentence.
-.
-.P
-The following example shows how optimal roff editing could look.
-.
-.IP
-.nf
-This is an example for a roff document.
-.Text .
-This is the next sentence in the same paragraph.
-.Text .
-This is a longer sentence stretching over several
-lines; abbreviations like `cf.' are easily
-identified because the dot is not followed by a
-line break.
-.Text .
-In the output, this will still go to the same
-paragraph.
-.fi
-.
-.P
-Besides Emacs, some other editors provide nroff style files too, e.g.\&
-.BR vim (1),
-an extension of the
-.BR vi (1)
-program.

-.TH GRODVI @MAN1EXT@ "@MDATE@" "Groff Version @VERSION@"
-.SH NAME
-grodvi \- convert groff output to TeX dvi format
-.
-.
-.SH SYNOPSIS
-.B grodvi
-[
-.B \-dlv
-] [
-.BI \-F dir
-] [
-.BI \-p papersize
-] [
-.BI \-w n
-] [
-.IR files \|.\|.\|.\&
-]
-.PP
-It is possible to have whitespace between a command line option and its
-parameter.
-.
-.
-.SH DESCRIPTION
-.B grodvi
-is a driver for
-.B groff
-that produces \*(tx dvi format.
-.
-Normally it should be run by
-.BR groff\ \-Tdvi .
-.
-This will run
-.BR @g@troff\ \-Tdvi ;
-it will also input the macros in
-.BR @MACRODIR@/dvi.tmac .
-.
-.LP
-The dvi file generated by
-.B grodvi
-can be printed by any correctly-written dvi driver.
-.
-The troff drawing primitives are implemented
-using the tpic version\~2 specials.
-.
-If the driver does not support these, the
-.B \[rs]D
-commands will not produce any output.
-.
-.LP
-There is an additional drawing command available:
-.
-.TP
-.BI \[rs]D'R\  dh\ dv '
-Draw a rule (solid black rectangle), with one corner
-at the current position, and the diagonally opposite corner
-at the current position
-.RI +( dh , dv ).
-.
-Afterwards the current position will be at the opposite corner.
-.
-This produces a rule in the dvi file and so can be printed even with a
-driver that does not support the tpic specials unlike the other
-.B \[rs]D
-commands.
-.
-.LP
-The groff command
-.BI \[rs]X' anything '
-is translated into the same command in the dvi file as would be
-produced by
-.BI \[rs]special{ anything }
-in \*(tx;
-.I anything
-may not contain a newline.
-.
-.LP
-For inclusion of EPS image files,
-.B \-Tdvi
-loads
-.B pspic.tmac
-automatically, providing the
-.B PSPIC
-macro.
-.
-Please check
-.BR groff_tmac (@MAN5EXT@)
-for a detailed description.
-.
-.LP
-Font files for
-.B grodvi
-can be created from tfm files using
-.BR tfmtodit (@MAN1EXT@).
-.
-The font description file should contain the following
-additional commands:
-.
-.Tp \w'\fBinternalname'u+2n
-.BI internalname\   name
-The name of the tfm file (without the
-.B .tfm
-extension) is
-.IR name .
-.
-.TP
-.BI checksum\  n
-The checksum in the tfm file is
-.IR n .
-.
-.TP
-.BI designsize\  n
-The designsize in the tfm file is
-.IR n .
-.
-.LP
-These are automatically generated by
-.B tfmtodit.
-.
-.LP
-The default color for
-.B \[rs]m
-and
-.B \[rs]M
-is black.
-.
-Currently, the drawing color for
-.B \[rs]D
-commands is always black, and fill color values are translated to gray.
-.
-.LP
-In
-.B troff
-the
-.B \[rs]N
-escape sequence can be used to access characters by their position
-in the corresponding tfm file;
-all characters in the tfm file can be accessed this way.
-.
-.LP
-By design, the DVI format doesn't care about physical dimensions of the
-output medium.
-.
-Instead,
-.B grodvi
-emits the equivalent to \*(tx's
-.BI \[rs]special{papersize= width , length }
-on the first page;
-.B dvips
-(and possibly other DVI drivers) then sets the page size accordingly.
-.
-If either the page width or length is not positive, no papersize special
-is output.
-.
-.
-.SH OPTIONS
-.TP
-.B \-d
-Do not use tpic specials to implement drawing commands.
-.
-Horizontal and vertical lines will be implemented by rules.
-.
-Other drawing commands will be ignored.
-.
-.TP
-.BI \-F dir
-Prepend directory
-.IB dir /dev name
-to the search path for font and device description files;
-.I name
-is the name of the device, usually
-.BR dvi .
-.
-.TP
-.B \-l
-Specify landscape orientation.
-.
-.TP
-.BI \-p papersize
-Specify paper dimensions.
-.
-This overrides the
-.BR papersize ,
-.BR paperlength ,
-and
-.B paperwidth
-commands in the
-.B DESC
-file; it accepts the same arguments as the
-.B papersize
-command (see
-.BR groff_font (@MAN5EXT@)
-for details).
-.
-.TP
-.B \-v
-Print the version number.
-.
-.TP
-.BI \-w n
-Set the default line thickness to
-.I n
-thousandths of an em.
-If this option isn't specified, the line thickness defaults to 0.04\~em.
-.
-.
-.SH USAGE
-There are styles called
-.BR R ,
-.BR I ,
-.BR B ,
-and
-.B BI
-mounted at font positions 1 to\ 4.
-The fonts are grouped into families
-.B T
-and
-.B H\ \c
-having members in each of these styles:
-.
-.RS
-.TP
-.B TR
-.FT TR
-CM Roman (cmr10)
-.FT
-.
-.TQ
-.B TI
-.FT TI
-CM Text Italic (cmti10)

-.B HBI
-.FT HBI
-CM Slanted Sans Serif Bold Extended (cmssbxo10)
-.FT
-.RE
-.
-.LP
-There are also the following fonts which are not members of a family:
-.
-.RS
-.TP
-.B CW
-CM Typewriter Text (cmtt10)
-.FT CW
-.FT
-.
-.TQ
-.B CWI
-CM Italic Typewriter Text (cmitt10)
-.FT CWI
-.FT
-.RE
-.
-.LP
-Special fonts are
-.B MI
-(cmmi10),
-.B S
-(cmsy10),
-.B EX
-(cmex10),
-.B SC
-(cmtex10, only for
-.BR CW ),
-and, perhaps surprisingly,
-.BR TR ,
-.BR TI ,
-and
-.BR CW ,
-due to the different font encodings of text fonts.
-.
-For italic fonts,
-.B CWI
-is used instead of
-.BR CW .
-.
-.LP
-Finally, the symbol fonts of the American Mathematical Society are available
-as special fonts
-.B SA
-(msam10) and
-.B SB
-(msbm10).
-.
-These two fonts are not mounted by default.
-.
-.LP
-Using the option
-.B \-mec
-(which loads the file
-.BR ec.tmac )
-provides the EC and TC fonts.
-.
-The design of the EC family is very similar to that of the CM fonts;
-additionally, they give a much better coverage of groff symbols.
-.
-Note that
-.B ec.tmac
-must be called before any language-specific files; it doesn't take care of
-hcode values.

-.SH BUGS
-Dvi files produced by
-.B grodvi
-use a different resolution (57816 units per inch) to those produced by
-\*(tx.
-.
-Incorrectly written drivers which assume the resolution used by \*(tx,
-rather than using the resolution specified in the dvi file will not
-work with
-.BR grodvi .
-.
-.LP
-When using the
-.B \-d
-option with boxed tables,
-vertical and horizontal lines can sometimes protrude by one pixel.
-.
-This is a consequence of the way \*(tx requires that the heights
-and widths of rules be rounded.

-.SH DESCRIPTION
-The
-.B grohtml
-front end (which consists of a preprocessor,
-.BR pre-grohtml ,
-and a device driver,
-.BR post-grohtml )
-translates the output of GNU
-.B troff
-to html.
-Users should always invoke
-.B grohtml
-via the groff command with a
-.B \-Thtml
-option.
-If no files are given,
-.B grohtml
-will read the standard input.
-A filename of
-.B \-
-will also cause
-.B grohtml
-to read the standard input.
-Html output is written to the standard output.
-When
-.B grohtml
-is run by
-.B groff
-options can be passed to
-.B grohtml
-using
-.BR groff 's
-.B \-P
-option.
-.
-.
-.SH OPTIONS
-.TP
-.BI \-a aa-text-bits
-Number of bits of antialiasing information to be used by
-.I text
-when generating png images.
-The default is\~4 but valid values are 0, 1, 2, and\~4.
-Note your version of
-.B gs
-needs to support the
-.B \%\-dTextAlphaBits
-and
-.B \%\-dGraphicAlphaBits
-options in order to exploit antialiasing.
-A value of\~0 stops
-.B grohtml
-from issuing antialiasing commands to
-.BR gs .
-.
-.TP
-.B \-b
-Initialize the background color to white.
-.
-.TP
-.BI \-D dir
-Inform
-.B grohtml
-to place all image files into directory
-.IR dir .
-.
-.TP
-.BI \-F dir
-Prepend directory
-.IB dir /dev name
-to the search path for font and device description files;
-.I name
-is the name of the device, usually
-.BR html .
-.
-.TP
-.BI \-g aa-graphic-bits
-Number of bits of antialiasing information to be used by
-.I graphics
-when generating png images.
-The default is\~4 but valid values are 0, 1, 2, and\~4.
-Note your version of
-.B gs
-needs to support the
-.B \%\-dTextAlphaBits
-and
-.B \%\-dGraphicAlphaBits
-options in order to exploit antialiasing.
-A value of\~0 stops
-.B grohtml
-from issuing antialiasing commands to
-.BR gs .
-.
-.TP
-.B \-h
-Generate section and number headings by using
-.BR <B> .\|.\|. </B>
-and increasing the font size, rather than using the
-.BI <H n >\c
-\&.\|.\|.\c
-.BI </H n >
-tags.
-.
-.TP
-.BI \-i resolution
-Select the resolution for all images.
-By default this is 100 pixels per inch.
-Example:
-.B \-i200
-indicates 200 pixels per inch.
-.
-.TP
-.BI \-I stem
-Determine the image stem name.
-If omitted grohtml uses
-.BI \%grohtml- XXX
-.RI ( XXX
-is the process ID).
-.
-.TP
-.BI \-j filename
-Inform
-.B grohtml
-to split the html output into multiple files.
-The
-.I filename
-is the stem and specified section headings
-(default is level one) start a new file, named
-.IR filename-n.html .
-.
-.TP
-.B \-l
-Turn off the production of automatic section links at the top of the
-document.
-.
-.TP
-.B \-n
-Generate simple heading anchors whenever a section/number heading is found.
-Without the option the anchor value is the textual heading.
-This can cause problems when a heading contains a `?' on older versions of
-some browsers (Netscape).
-This flag is automatically turned on if a heading contains an image.
-.
-.TP
-.BI \-o vertical-offset
-Specify the vertical offset of images in points.
-.
-.TP
-.B \-p
-Display page rendering progress to stderr.
-.B grohtml
-only displays a page number when an image is required.
-.
-.TP
-.B \-r
-Turn off the automatic header and footer line (html rule).
-.
-.TP
-.B \-s size
-Set the base point size of the source file.
-Thereafter when this point size is used in the source it will correspond
-to the html base size.
-Every increase of two points in the source will yield a
-.B <big>
-tag, and conversely when a decrease of two points is seen a
-.B <small>
-tag is emitted.
-.
-.TP
-.BI \-S level
-When splitting html output,
-split at the heading level (or higher) defined by
-.IR level .
-.
-.TP
-.B \-v
-Print the version number.
-.
-.
-.SH USAGE
-There are styles called
-.BR R ,
-.BR I ,
-.BR B ,
-and
-.B BI
-mounted at font positions 1 to\~4.
-.
-.
-.SH DEPENDENCIES
-.B grohtml
-is dependent upon the png utilities
-.RB ( \%pnmcut ,
-.BR \%pnmcrop ,
-.BR \%pnmtopng )
-and GhostScript
-.RB ( gs ).
-.B \%pnmtopng
-(version 2.37.6 or greater)
-and
-.B \%pnmcut
-from the netpbm package (version 9.16 or greater) will work also.
-It is also dependent upon
-.B \%psselect
-from the
-.B PSUtils
-package.
-Images are generated whenever a table, picture, equation or line is
-encountered.
-.
-.
-.SH BUGS
-.B Grohtml
-has been completely redesigned and rewritten.
-It is still beta code.

-available:
-.TP
-.BI \eD'R\  dh\ dv '
-Draw a rule (i.e.\ a solid black rectangle), with one corner at the current
-position, and the diagonally opposite corner at the current position
-.RI +( dh , dv ).
-.SH OPTIONS
-Note that there can be whitespace between a one-letter option and its

-.BI \-\-orientation= orientation
-Print the document with
-.I orientation
-orientation, which must be `portrait' or `landscape'.
-.TP
-.BI \-w width

-.I name
-is the name of the device, usually
-.BR lbp .
-.TP
-.B \-h
-.TQ
-.B \-\-help
-Print a short help text.
-.SH TYPEFACES
-The driver supports the Dutch, Swiss and Swiss-Narrow scalable typefaces,
-each one in the Regular, Bold, Italic and Bold-Italic styles.
-Additionally, the Courier and Elite monospaced typefaces at the sizes 8 and
-12 points (for Courier) resp. 8 and 10 points (for Elite) are supported,
-each one in the Regular, Bold and Italic styles.
-.PP
-The following chart summarizes the font names you can use to access these
-fonts:
-.PP
-.TS
-tab(|) allbox center;
-c c c c c
-ab c c c c
-.
-Typeface | Regular | Bold | Italic | Bold-Italic
-Dutch | TR | TB | TI | TBI
-Swiss | HR | HB | HI | HBI
-Swiss Narrow | HNR | HNB | HNI | HNBI
-Courier | CR | CB | CI |
-Elite | ER | EB | EI |
-.TE
-.PP
-.SH PAPER SIZES
-The paper size can be set in the
-.B DESC
-file or with command line options to
-.BR grolbp .
-If the paper size is specified both ways, the command line options take
-precedence over the contents of the
-.B DESC
-file (this applies to the page orientation too).
-.PP
-See
-.BR groff_font (@MAN1EXT@)
-how to set the paper dimensions in the
-.B DESC
-file.
-.PP
-To set the paper size in the command line, add
-.sp 1
-.in +2m
-.BI \-p \ paper-size
-.in -2m
-.sp 1
-or
-.sp 1
-.in +2m
-.BI \-\-papersize= paper-size
-.in -2m
-.sp 1
-to the other
-.B grolbp
-options, where
-.I paper-size
-is in the same format as in the
-.B DESC
-file.
-.PP
-If no paper size is specified in the
-.B DESC
-file or the command line, a default size of A4 is used.
-.SH PAGE ORIENTATION
-As with the page size, the orientation of the printed page
-.RB ( portrait
-or
-.BR landscape )
-can be set in the
-.B DESC
-file or with command line options.
-It is also case insensitive.
-.PP
-To set the orientation in the
-.B DESC
-file, insert a line with the following content:
-.sp 1
-.in +2m
-.B orientation
-.RB [ portrait | landscape ]
-.in -2m
-.sp 1
-Only the first valid orientation command in the
-.B DESC
-file is used.
-.PP
-To set the page orientation with command line options you can use the
-.B \-o
-or
-.B \-\-orientation
-option with the same parameters
-.RB ( portrait
-or
-.BR landscape )
-as in the
-.B DESC
-file.
-Or you can use the
-.B \-l
-option to force the pages to be printed in landscape.
-.SH FONT FILE FORMAT
-In addition to the usual commands described in
-.BR groff_font (@MAN5EXT@),
-.B grolbp
-provides the command
-.I lbpname
-which sets the font name sent to the printer when requesting this font.
-The syntax of this command is:
-.sp 1
-.in +2m
-.B lbpname
-.I printer_font_name
-.in -2m
-.IP \(bu
-For bitmapped fonts,
-.I printer_font_name
-has the form
-.sp 1
-.in +2m
-.RI N\(la base_fontname \(ra\(la font_style \(ra
-.in -2m
-.sp 1
-.I base_fontname 
-is the font name as it appears in the printers font listings without the
-first letter, up to (but not including) the font size.
-.I font_style
-can be one of the letters
-.BR R ,
-.BR I ,
-or
-.BR B ,
-indicating the font styles Roman, Italic and Bold respectively.
-.IP
-For instance, if the printer's 
-.I font listing A
-shows font `Nelite12I.ISO_USA', the corresponding entry in the font
-description file is
-.sp 1
-.in +2m
-.B lbpname NeliteI
-.in -2m
-.IP
-Note that you may need to modify
-.B grolbp
-to add support for new bitmapped fonts, since the available font names and
-font sizes of bitmapped fonts (as documented above) are hard-coded into the
-program.
-.IP \(bu
-For scalable fonts,
-.I printer_font_name
-is identical to the font name as it appears in the printer's 
-.IR "font listing A" .
-.IP
-For instance, to select the `Swiss' font in bold style, which appears in
-the printer's
-.I font listing A
-as `Swiss-Bold', the required
-.B lbpname
-command line is
-.sp 1
-.in +2m
-.B lbpname Swiss-Bold
-.in -2m
-.sp 1
-.PP
-The argument of
-.B lbpname
-is case sensitive.

-.SH DESCRIPTION
-.B grolj4
-is a driver for
-.B groff
-that produces output in PCL5 format suitable for an HP Laserjet 4 printer.
-.LP
-There is an additional drawing command available:
-.TP
-.BI \eD'R\  dh\ dv '
-Draw a rule (solid black rectangle), with one corner
-at the current position, and the diagonally opposite corner
-at the current position
-.RI +( dh , dv ).
-Afterwards the current position will be at the opposite corner.  This
-generates a PCL fill rectangle command, and so will work on
-printers that do not support HPGL/2 unlike the other
-.B \eD
-commands.
-.SH OPTIONS
-.TP
-.BI \-c n
-Print
-.I n
-copies of each page.
-.TP
-.B \-l
-Print the document with a landscape orientation.
-.TP
-.BI "\-d [" n ]
-Use duplex mode
-.IR n :
-1\ is long-side binding; 2\ is short-side binding;
-default is\ 1.
-.TP
-.BI \-p size
-Set the paper size to
-.IR size ,
-which must be one of
-letter, legal, executive, a4, com10, monarch, c5, b5, dl.
-.TP
-.B \-v
-Print the version number.
-.TP
-.BI \-w n
-Set the default line thickness to
-.I n
-thousandths of an em.
-If this option isn't specified, the line thickness defaults to 0.04\~em.
-.TP
-.BI \-F dir
-Prepend directory
-.IB dir /dev name
-to the search path for font and device description files;
-.I name
-is the name of the device, usually
-.BR lj4 .
-.LP
-The following four commands are available additionally in the
-font description files:
-.TP
-.BI pclweight \ N
-The integer value
-.I N
-must be in the range -7 to +7; default is 0.
-.TP
-.BI pclstyle \ N
-The integer value
-.I N
-must be in the range 0 to 32767; default is 0.
-.TP
-.BI pclproportional \ N
-A boolean flag which can be either 0 or 1; default is 0.
-.TP
-.BI pcltypeface \ N
-The integer value
-.I N
-must be in the range 0 to 65535; default is 0.

-.TH LJ4_FONT @MAN5EXT@ "@MDATE@" "Groff Version @VERSION@"
-.\" --------------------------------------------------------------------------
-.SH NAME
-.\" --------------------------------------------------------------------------
-lj4_font \- groff fonts for use with devlj4
-.\" --------------------------------------------------------------------------
-.SH DESCRIPTION
-.\" --------------------------------------------------------------------------
-Nominally, all Hewlett-Packard LaserJet~4\(enseries and newer printers
-have the same internal fonts: 45 scalable fonts and one bitmapped
-Lineprinter font.
-The scalable fonts are available in sizes between 0.25 point and 999.75
-points, in 0.25-point increments; the Lineprinter font is available only
-in 8.5-point size.
-.LP
-The LaserJet font files included with
-.B groff
-assume that all printers since the LaserJet~4 are identical.
-There are some differences between fonts in the earlier and more recent
-printers, however.
-The LaserJet~4 printer used Agfa Intellifont technology for 35 of the
-internal scalable fonts; the remaining 10 scalable fonts were TrueType.
-Beginning with the LaserJet~4000\(enseries printers introduced in 1997,
-all scalable internal fonts have been TrueType.
-The number of printable glyphs differs slightly between Intellifont and
-TrueType fonts (generally, the TrueType fonts include more glyphs), and
-there are some minor differences in glyph metrics.
-Differences among printer models are described in the
-.I "PCL~5 Comparison Guide"
-and the
-.I "PCL~5 Comparison Guide Addendum"
-(for printers introduced since approximately 2001).
-.LP
-LaserJet printers reference a glyph by a combination of a 256-glyph
-symbol set and an index within that symbol set.
-Many glyphs appear in more than one symbol set; all combinations of
-symbol set and index that reference the same glyph are equivalent.
-For each glyph,
-.BR hpftodit (@MAN1EXT@)
-searches a list of symbol sets, and selects the first set that contains
-the glyph.
-The printing code generated by
-.BR hpftodit (@MAN1EXT@)
-is an integer that encodes a numerical value for the symbol set in the
-high byte(s), and the index in the low byte.
-See
-.BR groff_font (@MAN5EXT@)
-for a complete description of the font file format; symbol sets are
-described in greater detail in the
-.IR "PCL~5 Printer Language Technical Reference Manual" .
-.LP
-Two of the scalable fonts, Symbol and Wingdings, are bound to
-256-glyph symbol sets; the remaining scalable fonts, as well as the
-Lineprinter font, support numerous symbol sets, sufficient to enable
-printing of more than 600 glyphs.
-.LP
-The metrics generated by
-.BR hpftodit (@MAN1EXT@)
-assume that the DESC file contains values of 1200 for res and 6350 for
-unitwidth (or any combination (e.g., 2400 and 3175) for which
-res~\(mu~unitwidth~=~7\|620\|000).
-Although HP PCL~5 LaserJet printers support an internal resolution of
-7200 units per inch, they use a 16-bit signed integer for cursor
-positioning; if
-.B devlj4
-is to support U.S. ledger paper (11\(sd~\(mu~17\(sd), the maximum usable
-resolution is 32\|767~/~17, or 1927, units per inch, which rounds down to
-1200 units per inch.
-If the largest required paper size is less (e.g., 8.5\(sd~\(mu~11\(sd or
-A5), a greater resolution (and lesser unitwidth) can be specified.
-.\" --------------------------------------------------------------------------
-.SH LIMITATIONS
-.\" --------------------------------------------------------------------------
-Font metrics for Intellifont fonts were provided by Tagged Font Metric
-(TFM) files originally developed by Agfa/Compugraphic.
-The TFM files provided for these fonts supported 600+ glyphs and
-contained extensive lists of kern pairs.
-.LP
-To accommodate developers who had become accustomed to TFM files, HP also
-provided TFM files for the 10 TrueType fonts included in the LaserJet~4.
-The TFM files for TrueType fonts generally included less information
-than the Intellifont TFMs, supporting fewer glyphs, and in most cases,
-providing no kerning information.
-By the time the LaserJet~4000 printer was introduced, most
-developers had migrated to other means of obtaining font metrics,
-and support for new TFM files was very limited.
-The TFM files provided for the TrueType fonts in the LaserJet~4000
-support only the Latin 2 (ISO 8859-2) symbol set, and include no kerning
-information; consequently, they are of little value for any but the most
-rudimentary documents.
-.LP
-Because the Intellifont TFM files contain considerably more information,
-they generally are preferable to the TrueType TFM files even for use
-with the TrueType fonts in the newer printers.
-The metrics for the TrueType fonts are very close, though not identical,
-to those for the earlier Intellifont fonts of the same names.
-Although most output using the Intellifont metrics with the newer
-printers is quite acceptable, a few glyphs may fail to print as
-expected.
-The differences in glyph metrics may be particularly noticeable with
-composite parentheses, brackets, and braces used by
-.BR eqn (@MAN1EXT@) .
-A script, located in
-.BR @FONTDIR@/devlj4/generate ,
-can be used to adjust the metrics for these glyphs in the special font S
-for use with printers that have all TrueType fonts.
-.LP
-At the time HP last supported TFM files, only Version 1 of the Unicode
-standard was available.
-Consequently, many glyphs lacking assigned code points were assigned by
-HP to the Private Use Area (PUA).
-Later versions of the Unicode standard included code points outside the
-PUA for many of these glyphs.
-The HP-supplied TrueType TFM files use the PUA assignments;
-TFM files generated from more recent TrueType font files require the
-later Unicode values to access the same glyphs.
-Consequently, two different mapping files may be required: one for the
-HP-supplied TFM files, and one for more recent TFM files.

-.SH DESCRIPTION
-.B grops
-translates the output of GNU
-.B troff
-to PostScript.
-.
-Normally
-.B grops
-should be invoked by using the groff command
-with a
-.B \-Tps
-option.
-.
-.if '@DEVICE@'ps' (Actually, this is the default for groff.)
-.
-If no files are given,
-.B grops
-will read the standard input.
-.
-A filename of
-.B \-
-will also cause
-.B grops
-to read the standard input.
-.
-PostScript output is written to the standard output.
-.
-When
-.B grops
-is run by
-.B groff
-options can be passed to
-.B grops
-using the
-.B groff
-.B \-P
-option.
-.
-.PP
-Note that
-.B grops
-doesn't produce a valid document structure (conforming to the Document
-Structuring Convention) if called with multiple file arguments.
-.
-To print such concatenated output it is necessary to deactivate DSC
-handling in the printing program or previewer.
-.
-.
-.SH OPTIONS
-.TP
-.BI \-b n
-Provide workarounds for older printers, broken spoolers, and previewers.
-.
-Normally
-.B grops
-produces output at PostScript LanguageLevel\~2 that conforms to the
-Document Structuring Conventions version 3.0.
-.
-Some older printers, spoolers, and previewers can't handle such output.
-.
-The value of\~\c
-.I n
-controls what
-.B grops
-does to make its output acceptable to such programs.
-.
-A value of\~0 will cause grops not to employ any workarounds.
-.
-.IP
-Add\~1 if no
-.B %%Begin\%Document\%Setup
-and
-.B %%End\%Document\%Setup
-comments should be generated;
-this is needed for early versions of TranScript that get confused by
-anything between the
-.B %%End\%Prolog
-comment and the first
-.B %%Page
-comment.
-.
-.IP
-Add\~2 if lines in included files beginning with
-.B %!
-should be stripped out; this is needed for Sun's pageview previewer.
-.
-.IP
-Add\~4 if
-.BR %%Page ,
-.BR %%Trailer
-and
-.B %%End\%Prolog
-comments should be
-stripped out of included files; this is needed for spoolers that
-don't understand the
-.B %%Begin\%Document
-and
-.B %%End\%Document
-comments.
-.
-.IP
-Add\~8 if the first line of the PostScript output should be
-.B %!PS-Adobe-2.0
-rather than
-.BR %!PS-Adobe-3.0 ;
-this is needed when using Sun's Newsprint with a printer that requires
-page reversal.
-.
-.IP
-Add\~16 if no media size information should be included in the document
-(this is, neither use
-.B %%Document\%Media
-nor the
-.B setpagedevice
-PostScript command).
-.
-This was the behaviour of groff version 1.18.1 and earlier; it is needed
-for older printers which don't understand PostScript LanguageLevel\~2.
-.
-It is also necessary if the output is further processed to get an
-encapsulated PS (EPS) file -- see below.
-.
-.IP
-The default value can be specified by a
-.
-.RS
-.IP
-.BI broken\  n
-.
-.LP
-command in the DESC file.
-.
-Otherwise the default value is\~0.
-.RE
-.
-.TP
-.BI \-c n
-Print
-.I n
-copies of each page.
-.
-.TP
-.BI \-F dir
-Prepend directory
-.IB dir /dev name
-to the search path for prologue, font, and device description files;
-.I name
-is the name of the device, usually
-.BR ps .
-.
-.TP
-.BI \-g
-Guess the page length.
-.
-This generates PostScript code that guesses the page length.
-.
-The guess will be correct only if the imageable area is vertically
-centered on the page.
-.
-This option allows you to generate documents that can be printed
-both on letter (8.5\(mu11) paper and on A4 paper without change.
-.
-.TP
-.BI \-I dir
-This option may be used to specify a directory to search for
-files on the command line and files named in 
-.B \eX'ps: import'
-and
-.B \eX'ps: file'
-escapes.
-The current directory is always searched first.
-This option may be specified more than once;
-the directories will be searched in the order specified.
-No directory search is performed for files specified using an absolute path.
-.
-.TP
-.B \-l
-Print the document in landscape format.
-.
-.TP
-.B \-m
-Turn manual feed on for the document.
-.
-.TP
-.BI \-p paper-size
-Set physical dimension of output medium.
-.
-This overrides the
-.BR papersize ,
-.BR paperlength ,
-and
-.B paperwidth
-commands in the
-.B DESC
-file; it accepts the same arguments as the
-.B papersize
-command.
-.
-See
-.B groff_font (@MAN5EXT@)
-for details.
-.
-.TP
-.BI \-P prologue-file
-Use the file

-The arguments
-.IR llx ,
-.IR lly ,

-are integers that give the desired width and height in groff
-units of the graphic.
-.
-The graphic will be scaled so that it has this width and height
-and translated so that the lower left corner of the graphic is
-located at the position associated with
-.B \[rs]X

-.
-If the height argument is omitted it will be scaled uniformly in the
-x and y\~directions so that it has the specified width.
-.
-Note that the contents of the

-.RE
-.
-.LP
-The input to
-.B grops
-must be in the format output by
-.BR @g@troff (@MAN1EXT@).
-.
-This is described in
-.BR groff_out (@MAN5EXT@).
-.
-.LP
-In addition, the device and font description files for the device used
-must meet certain requirements.
-.
-The device and font description files supplied for
-.B ps
-device meet all these requirements.
-.
-.BR afmtodit (@MAN1EXT@)
-can be used to create font files from AFM files.
-.
-The resolution must be an integer multiple of\~72 times the
-.BR sizescale .
-.
-The
-.B ps
-device uses a resolution of 72000 and a sizescale of 1000.
-.
-.LP
-The device description file must contain a valid paper size; see
-.BR groff_font (@MAN5EXT@)
-for more information.
-.
-.LP
-Each font description file must contain a command
-.IP
-.BI internalname\  psname
-.LP
-which says that the PostScript name of the font is
-.IR psname .
-.
-It may also contain a command
-.IP
-.BI encoding\  enc_file
-.LP
-which says that
-the PostScript font should be reencoded using the encoding described in
-.IR enc_file ;
-this file should consist of a sequence of lines of the form:
-.IP
-.I
-pschar code
-.LP
-where
-.I pschar
-is the PostScript name of the character,
-and
-.I code
-is its position in the encoding expressed as a decimal integer; valid
-values are in the range 0 to\~255.
-.
-Lines starting with
-.B #
-and blank lines are ignored.
-.
-The code for each character given in the font file must correspond
-to the code for the character in encoding file, or to the code in the default
-encoding for the font if the PostScript font is not to be reencoded.
-.
-This code can be used with the
-.B \[rs]N
-escape sequence in
-.B troff
-to select the character,
-even if the character does not have a groff name.
-.
-Every character in the font file must exist in the PostScript font, and 
-the widths given in the font file must match the widths used
-in the PostScript font.
-.
-.B grops
-will assume that a character with a groff name of
-.B space
-is blank (makes no marks on the page);
-it can make use of such a character to generate more efficient and
-compact PostScript output.
-.
-.LP
-Note that
-.B grops
-is able to display all glyphs in a PostScript font, not only 256.
-.I enc_file
-(or the default encoding if no encoding file specified) just defines the
-order of glyphs for the first 256 characters; all other glyphs are
-accessed with additional encoding vectors which
-.B grops
-produces on the fly.
-.
-.LP
-.B grops
-can automatically include the downloadable fonts necessary
-to print the document.
-Such fonts must be in PFA format.
-Use
-.BR pfbtops (@MAN1EXT@)
-to convert a Type\~1 font in PFB format.
-Any downloadable fonts which should, when required, be included by
-.B grops
-must be listed in the file
-.BR @FONTDIR@/devps/download ;
-this should consist of lines of the form
-.
-.IP
-.I
-font filename
-.
-.LP
-where
-.I font
-is the PostScript name of the font,
-and
-.I filename
-is the name of the file containing the font;
-lines beginning with
-.B #
-and blank lines are ignored;
-fields may be separated by tabs or spaces;
-.I filename
-will be searched for using the same mechanism that is used
-for groff font metric files.
-.
-The
-.B download
-file itself will also be searched for using this mechanism;
-currently, only the first found file in the font path is used.
-.
-.LP
-If the file containing a downloadable font or imported document
-conforms to the Adobe Document Structuring Conventions,
-then
-.B grops
-will interpret any comments in the files sufficiently to ensure that its
-own output is conforming.
-.
-It will also supply any needed font resources that are listed in the
-.B download
-file
-as well as any needed file resources.
-.
-It is also able to handle inter-resource dependencies.
-.
-For example, suppose that you have a downloadable font called Garamond,
-and also a downloadable font called Garamond-Outline
-which depends on Garamond
-(typically it would be defined to copy Garamond's font dictionary,
-and change the PaintType),
-then it is necessary for Garamond to appear before Garamond-Outline
-in the PostScript document.
-.
-.B grops
-will handle this automatically
-provided that the downloadable font file for Garamond-Outline
-indicates its dependence on Garamond by means of
-the Document Structuring Conventions,
-for example by beginning with the following lines
-.
-.IP
-.B
-%!PS-Adobe-3.0 Resource-Font
-.br
-.B
-%%DocumentNeededResources: font Garamond
-.br
-.B
-%%EndComments
-.br
-.B
-%%IncludeResource: font Garamond
-.
-.LP
-In this case both Garamond and Garamond-Outline would need to be listed
-in the
-.B download
-file.
-.
-A downloadable font should not include its own name in a
-.B %%Document\%Supplied\%Resources
-comment.
-.
-.LP
-.B grops
-will not interpret 
-.B %%Document\%Fonts
-comments.
-.
-The
-.BR %%Document\%Needed\%Resources ,
-.BR %%Document\%Supplied\%Resources ,
-.BR %%Include\%Resource ,
-.BR %%Begin\%Resource ,
-and
-.BR %%End\%Resource
-comments
-(or possibly the old
-.BR %%Document\%Needed\%Fonts ,
-.BR %%Document\%Supplied\%Fonts ,
-.BR %%Include\%Font ,
-.BR %%Begin\%Font ,
-and
-.BR %%End\%Font
-comments)
-should be used.
-.
-.
-.SS Encapsulated PostScript
-.B grops
-itself doesn't emit bounding box information.
-.
-With the help of GhostScript the following commands will produce an
-encapsulated PS file
-.B foo.eps
-from input file
-.BR foo :
-.
-.IP
-.B
-groff -P-b16 foo > foo.ps
-.br
-.B
-gs -dNOPAUSE -sDEVICE=bbox -- foo.ps 2> foo.bbox
-.br
-.B
-cat foo.ps | sed \-e '/%%Orientation/rfoo.bbx' > foo.eps
-.br
-.B
-rm foo.bbx
-.br
-.
-.
-.
-.SS TrueType fonts
-TrueType fonts can be used with 
-.B grops 
-if converted first to 
-.B "Type 42"
-format, an especial PostScript wrapper equivalent to the
-PFA format mentioned in
-.BR pfbtops (@MAN1EXT@).
-There are several different methods to generate a type42 
-wrapper and most of them involve the use of a PostScript
-interpreter such as Ghostscript \(em see
-.BR gs (1).
-Yet, the easiest method involves the use of the application 
-.BR ttftot42 .
-This program uses
-.BR freetype (3)
-(version 1.3.1) to generate type42
-font wrappers and well-formed AFM files that can be fed to
-the
-.BR afmtodit (@MAN1EXT@)
-script to create appropriate metric files.
-The resulting font wrappers should be added to the
-.B download
-file.
-.B ttftot42
-source code can be downloaded from

-These are patches to makes psfig work with groff.  They apply to the
-version of psfig in comp.sources.unix/Volume11.  After applying them,
-psfig should be recompiled with -DGROFF.  The resulting psfig will
-work only with groff, so you might want to install it under a
-different name.  The output of this psfig must be processed using the
-macros in the file ../tmac/tmac.psfig.  These will automatically add
-the necessary PostScript code to the prologue output by grops.  Use of
-the `global' feature in psfig will result in non-conformant PostScript
-which will fail if processed by a page reversal program.  Note that
-psfig is unsupported by me (I'm not interested in hearing about psfig
-problems.)  For new documents, I recommend using the PostScript
-inclusion features provided by grops.

-.SH NAME
-grotty \- groff driver for typewriter-like devices
-.
-.
-.SH SYNOPSIS
-.B grotty
-[
-.B \-bBcdfhioruUv
-] [
-.BI \-F dir
-] [
-.IR files \|.\|.\|.\&
-]
-.PP
-It is possible to have whitespace between the
-.B \-F
-option and its parameter.
-.
-.
-.SH DESCRIPTION
-.B grotty
-translates the output of GNU
-.B troff
-into a form suitable for typewriter-like devices.
-Normally
-.B grotty
-should be invoked by using the
-.B groff
-command
-with a
-.BR \-Tascii ,
-.BR \-Tlatin1 ,
-.B \-Tkoi8-r
-or
-.B \-Tutf8
-option on ASCII based systems, and with
-.B \-Tcp1047
-and
-.B \-Tutf8
-on EBCDIC based hosts.
-If no files are given,
-.B grotty
-will read the standard input.
-A filename of
-.B \-
-will also cause
-.B grotty
-to read the standard input.
-Output is written to the standard output.
-.LP
-By default,
-.B grotty
-emits SGR escape sequences (from ISO 6429, also called ANSI color escapes)
-to change text attributes (bold, italic, colors).
-This makes it possible to have eight different \M[green]background\M[]
-and \m[red]foreground\m[] colors; additionally, bold and italic
-attributes can be used \f[BI]at the same time\f[] (by using the BI font).
-.LP
-The following colors are defined in
-.BR tty.tmac :
-black, white, red, green, blue, yellow, magenta, cyan.
-Unknown colors are mapped to the default color (which is dependent on the
-settings of the terminal; in most cases, this is black for the foreground
-and white for the background).
-.LP
-Use the
-.B \-c
-switch to revert to the old behaviour, printing a bold character
-.I c
-with the sequence
-.RI ` c
-.SM BACKSPACE
-.IR c '
-and an italic character
-.I c
-by the sequence
-.RB ` _
-.SM BACKSPACE
-.IR c '.
-At the same time, color output is disabled.
-The same effect can be achieved by setting either the
-.B GROFF_NO_SGR
-environment variable or using the `sgr' X command (see below).
-.LP
-For SGR support, it is necessary to use the
-.B \-R
-option of
-.BR less (1)
-to disable the interpretation of
-.BR grotty 's
-old output format.
-Consequently, all programs which use
-.B less
-as the pager program have to pass this option to it.
-For
-.BR man (1)
-in particular, either add
-.B \-R
-to the
-.B $PAGER
-environment variable, e.g.\&
-.RS
-.LP
-.B PAGER="/usr/bin/less -R"
-.br
-.B export PAGER
-.RE
-.LP
-or use the
-.B \-P
-option of
-.B man
-to set the pager executable and its options, or modify the configuration
-file of
-.B man
-in a similar fashion.
-.LP
-.BR grotty 's
-old output format can be displayed on a terminal
-by piping through
-.BR ul (1).
-Pagers such as
-.BR more (1)
-or
-.BR less (1)
-are also able to display these sequences.
-Use either
-.B \-B
-or
-.B \-U
-when piping into
-.BR less (1);
-use
-.B \-b
-when piping into
-.BR more (1).
-There is no need to filter the output through
-.BR col (1)
-since
-.B grotty
-never outputs reverse line feeds.
-.LP
-The font description file may contain a command
-.IP
-.BI internalname\  n
-.LP
-where
-.I n
-is a decimal integer.
-If the 01 bit in
-.I n
-is set,
-then the font will be treated as an italic font;
-if the 02 bit is set,
-then it will be treated as a bold font.
-The code field in the font description field gives the
-code which will be used to output the character.
-This code can also be used in the
-.B \[rs]N
-escape sequence in
-.BR troff .
-.
-.
-.SH OPTIONS
-.TP
-.B \-b
-Suppress the use of overstriking for bold characters.
-Ignored if
-.B \-c
-isn't used.
-.
-.TP
-.B \-B
-Use only overstriking for bold-italic characters.
-Ignored if
-.B \-c
-isn't used.
-.
-.TP
-.B \-c
-Use
-.BR grotty 's
-old output format (see above).
-This also disables color output.
-.
-.TP
-.B \-d
-Ignore all
-.B \[rs]D
-commands.
-Without this
-.B grotty
-will render
-.B \[rs]D'l\|.\|.\|.\&'
-commands that have at least one zero argument
-(and so are either horizontal or vertical)
-using
-.BR \- ,
-.BR | ,
-and
-.B +
-characters.
-.
-.TP
-.B \-f
-Use form feeds in the output.
-A form feed will be output at the end of each page that has no output
-on its last line.
-.
-.TP
-.BI \-F dir
-Prepend directory
-.IB dir /dev name
-to the search path for font and device description files;
-.I name
-is the name of the device, usually
-.BR ascii ,
-.BR latin1 ,
-.BR koi8-r ,
-.BR utf8 ,
-or
-.BR cp1047 .
-.TP
-.B \-h
-Use horizontal tabs in the output.
-Tabs are assumed to be set every 8 columns.
-.
-.TP
-.B \-i
-Use escape sequences to set the italic text attribute instead of the
-underline attribute for italic fonts (`I' and `BI').
-Note that most terminals (including xterm) don't support this.
-Ignored if
-.B \-c
-is active.
-.
-.TP
-.B \-o
-Suppress overstriking (other than for bold or underlined characters in
-case the old output format has been activated with
-.BR \-c ).
-.
-.TP
-.B \-r
-Use escape sequences to set the reverse text attribute instead of the
-underline attribute for italic fonts (`I' and `BI').
-Ignored if
-.B \-c
-is active.
-.
-.TP
-.B \-u
-Suppress the use of underlining for italic characters.
-Ignored if
-.B \-c
-isn't used.
-.
-.TP
-.B \-U
-Use only underlining for bold-italic characters.
-Ignored if
-.B \-c
-isn't used.
-.
-.TP
-.B \-v
-Print the version number.
-.
-.
-.SH USAGE
-.B grotty
-understands a single X command produced using the
-.B \[rs]X
-escape sequence.
-.TP
-.BI \[rs]X'tty:\ sgr\  n '
-If
-.I n
-is non-zero or missing, enable SGR output (this is the default), otherwise
-use the old drawing scheme for bold and underline.
-.
-.
-.SH ENVIRONMENT
-.TP
-.B GROFF_NO_SGR
-If set, the old drawing scheme for bold and underline (using the
-backspace character) is active.
-Colors are disabled.

-device will be installed.
-.
-.
-.SH BUGS
-.LP
-.B grotty
-is intended only for simple documents.
-.LP
-There is no support for fractional horizontal or vertical motions.
-.LP
-There is no support for
-.B \[rs]D
-commands
-other than horizontal and vertical lines.
-.LP
-Characters above the first line (ie with a vertical position of\~0)
-cannot be printed.
-.LP
-Color handling is different compared to
-.BR grops (@MAN1EXT@).
-.B \[rs]M
-doesn't set the fill color for closed graphic objects (which
-.B grotty
-doesn't support anyway) but changes the background color of the character
-cell, affecting all subsequent operations.

-This is gxditview, an X11 previewer for groff based on MIT's xditview.
-This version can be used with the output of gtroff -Tps as well as
-with -TX75 and -TX100.  You will need X11R5 or newer to install it (it
-might work on X11R4, but I haven't tested it.)
-
-Previously, gxditview was installed in the usual place for X binaries
-(e.g., /usr/bin/X11); you have to remove it manually.
-
-xditview is copyrighted by MIT under the usual X terms (see
-gxditview.man); the changes to that which come along with the groff package
-are in the public domain.
-
-Please report bugs to bug-groff@gnu.org.

-.TH GXDITVIEW @MAN1EXT@ "@MDATE@" "Groff Version @VERSION@"
-.
-.
-.SH NAME
-gxditview \- display groff intermediate output files
-.
-.
-.SH SYNOPSIS
-.B \%gxditview
-.RI [\fB\- toolkitoption\  .\|.\|.\|]
-.RI [\fB\- option\  .\|.\|.\|]
-.RI [ filename ]
-.
-.
-.SH DESCRIPTION
-The
-.B \%gxditview 
-program displays the
-.I groff intermediate
-.IR output ,
-see
-.BR groff_out (@MAN5EXT@),
-on an X\~display.
-.
-It uses the standard X11 fonts, so it does not require access to the
-server machine for font loading.
-.
-There are several ways to use
-.BR \%gxditview .
-.
-.
-.PP
-The
-.I groff intermediate output
-can be generated by
-.BR groff\~\-Z .
-This can be viewed by explicity calling
-.B \%gxditview
-.IR \%filename .
-If
-.I filename
-is
-.BR \- ,
-.B \%gxditview
-will read the standard input;
-.I \%filename
-cannot be omitted.
-.
-The
-.I groff intermediate output
-is different for all devices.
-.
-.B \%gxditview
-can view it for all devices, but the quality is not always good.
-.
-.
-.PP
-The best result is achieved with the
-.BR X *
-devices for
-.BR groff 's
-option
-.BR \-T .
-.
-There are four
-.BR X *
-devices:
-.BR \%\-TX75 ,
-.BR \%\-TX75\-12 ,
-.BR \%\-TX100 ,
-.BR \%\-TX100\-12 .
-They differ by the X\~resolution (75dpi or 100dpi) and the used base font
-size (10pt or 12pt).
-.
-They are especially built for
-.BR \%gxditview .
-When using one of them
-.B groff
-generates the
-.I intermediate output
-for this device and calls
-.B \%gxditview
-automatically for viewing.
-.
-.
-.PP
-.BR groff 's
-option
-.B \-X
-should be considered obsolete today; it produces
-.I intermediate output
-for
-.I Postscript
-and uses
-.B \%gxditview
-as a viewer for it, but with a bad quality.
-.
-Simply don't use it.
-.
-.
-.PP
-During the run of
-.BR \%gxditview ,
-the left mouse button brings up a menu with the following entries:
-.
-.TP 8
-.B "Next Page"
-Display the next page.
-.
-.TP
-.B "Previous Page"
-Display the previous page.
-.
-.TP
-.B "Select Page"
-Select a particular numbered page specified by a dialog box.
-.
-.TP
-.B Print
-Print the
-.I groff intermediate output
-using a command specified by a dialog box.
-.
-The default command initially displayed is controlled by the
-.B printCommand
-application resource, and by the
-.B \-printCommand
-option.
-.
-.TP
-.B Open
-Open for display a new file specified by a dialog box.
-.
-The file should contain some
-.I groff intermediate
-.IR output .
-If the filename starts with
-.B |
-it will be taken to be a command to read from.
-.
-.TP
-.B Quit
-Exit from
-.BR \%gxditview .
-.
-.
-.PP
-The
-.IR n ,
-.I Space
-and
-.I Return
-keys are bound to the
-.B Next\ Page
-action.
-.
-The
-.IR p ,
-.I BackSpace
-and
-.I Delete
-keys are bound to the
-.B Previous\ Page
-action.
-.
-The
-.I q
-key is bound to the
-.B Quit
-action.
-.
-The
-.I r
-key is bound to the
-.B Rerasterize
-action which rereads the current file, and redisplays the current
-page; if the current file is a command, the command will be
-reexecuted.
-.
-.
-.PP
-The
-.B paperlength
-and
-.B paperwidth
-commands in the DESC file specify the length and width in machine units
-of the virtual page displayed by
-.BR \%gxditview .
-.
-.
-.SH OPTIONS
-The
-.B \%gxditview
-program accepts all of the standard X\~Toolkit command line options
-along with the additional options listed below:
-.
-.TP 8
-.B \-help
-This option indicates that a brief summary of the allowed options should be
-printed.

-.TP
-.B \-page
-This option specifies the page number of the document to be displayed.
-.
-.TP
-.BI \-backingStore\  backing-store-type
-Redisplay of the
-.I groff intermediate output
-window can take up to a second or so, this option causes the server to
-save the window contents so that when it is scrolled around the
-viewport, the window is painted from contents saved in backing store.
-.I backing-store-type
-can be one of
-.BR Always ,
-.B WhenMapped
-or 
-.BR NotUseful .
-.

-The default command displayed in the dialog box for the
-.B Print
-menu entry will be
-.IR command .
-.
-.TP
-.BI \-resolution\  res
-The
-.I groff intermediate output
-file will be displayed at a resolution of
-.I res
-dpi, unless the DESC file contains the
-.B X11
-command, in which case the device resolution will be used.
-.
-This corresponds to the
-.I Dvi
-widget's
-.B resolution
-resource.
-.
-The default is 75.
-.
-.TP
-.BI \-filename\  string
-The default filename displayed in the dialog box for the
-.B Open

-     This is what Unix does.
-     This mode of operation is selected by either setting the environment

-     PERMUTE is the default.  We permute the contents of ARGV as we

-     with character code 1.  Using `-' as the first character of the
-     list of option characters selects this mode of operation.
-
-     The special argument `--' forces an end of option-scanning regardless

-/* Description
-
-   This file implements the parser for the intermediate groff output,
-   see groff_out(5), and does the printout for the given device.
-
-   All parsed information is processed within the function do_file().
-   A device postprocessor just needs to fill in the methods for the class
-   `printer' (or rather a derived class) without having to worry about
-   the syntax of the intermediate output format.  Consequently, the
-   programming of groff postprocessors is similar to the development of
-   device drivers.
-
-   The prototyping for this file is done in driver.h (and error.h).
-*/
-
-/* Changes of the 2001 rewrite of this file.
-
-   The interface to the outside and the handling of the global
-   variables was not changed, but internally many necessary changes
-   were performed.
-
-   The main aim for this rewrite is to provide a first step towards
-   making groff fully compatible with classical troff without pain.
-
-   Bugs fixed
-   - Unknown subcommands of `D' and `x' are now ignored like in the
-     classical case, but a warning is issued.  This was also
-     implemented for the other commands.
-   - A warning is emitted if `x stop' is missing.
-   - `DC' and `DE' commands didn't position to the right end after
-     drawing (now they do), see discussion below.
-   - So far, `x stop' was ignored.  Now it terminates the processing
-     of the current intermediate output file like the classical troff.
-   - The command `c' didn't check correctly on white-space.
-   - The environment stack wasn't suitable for the color extensions
-     (replaced by a class).
-   - The old groff parser could only handle a prologue with the first
-     3 lines having a fixed structure, while classical troff specified
-     the sequence of the first 3 commands without further
-     restrictions.  Now the parser is smart about additional
-     white space, comments, and empty lines in the prologue.
-   - The old parser allowed space characters only as syntactical
-     separators, while classical troff had tab characters as well.
-     Now any sequence of tabs and/or spaces is a syntactical
-     separator between commands and/or arguments.
-   - Range checks for numbers implemented.
-
-   New and improved features
-   - The color commands `m' and `DF' are added.
-   - The old color command `Df' is now converted and delegated to `DFg'.
-   - The command `F' is implemented as `use intended file name'.  It
-     checks whether its argument agrees with the file name used so far,
-     otherwise a warning is issued.  Then the new name is remembered
-     and used for the following error messages.
-   - For the positioning after drawing commands, an alternative, easier
-     scheme is provided, but not yet activated; it can be chosen by
-     undefining the preprocessor macro STUPID_DRAWING_POSITIONING.
-     It extends the rule of the classical troff output language in a
-     logical way instead of the rather strange actual positioning.
-     For details, see the discussion below.
-   - For the `D' commands that only set the environment, the calling of
-     pr->send_draw() was removed because this doesn't make sense for
-     the `DF' commands; the (changed) environment is sent with the
-     next command anyway.
-   - Error handling was clearly separated into warnings and fatal.
-   - The error behavior on additional arguments for `D' and `x'
-     commands with a fixed number of arguments was changed from being
-     ignored (former groff) to issue a warning and ignore (now), see
-     skip_line_x().  No fatal was chosen because both string and
-     integer arguments can occur.
-   - The gtroff program issues a trailing dummy integer argument for
-     some drawing commands with an odd number of arguments to make the
-     number of arguments even, e.g. the DC and Dt commands; this is
-     honored now.
-   - All D commands with a variable number of args expect an even
-     number of trailing integer arguments, so fatal on error was
-     implemented.
-   - Disable environment stack and the commands `{' and `}' by making
-     them conditional on macro USE_ENV_STACK; actually, this is
-     undefined by default.  There isn't any known application for these
-     features.
-
-   Cosmetics
-   - Nested `switch' commands are avoided by using more functions.
-     Dangerous 'fall-through's avoided.
-   - Commands and functions are sorted alphabetically (where possible).
-   - Dynamic arrays/buffers are now implemented as container classes.
-   - Some functions had an ugly return structure; this has been
-     streamlined by using classes.
-   - Use standard C math functions for number handling, so getting rid
-     of differences to '0'.
-   - The macro `IntArg' has been created for an easier transition
-     to guaranteed 32 bits integers (`int' is enough for GNU, while
-     ANSI only guarantees `long int' to have a length of 32 bits).
-   - The many usages of type `int' are differentiated by using `Char',
-     `bool', and `IntArg' where appropriate.
-   - To ease the calls of the local utility functions, the parser
-     variables `current_file', `npages', and `current_env'
-     (formerly env) were made global to the file (formerly they were
-     local to the do_file() function)
-   - Various comments were added.
-
-   TODO
-   - Get rid of the stupid drawing positioning.
-   - Can the `Dt' command be completely handled by setting environment
-     within do_file() instead of sending to pr?
-   - Integer arguments must be >= 32 bits, use conditional #define.
-   - Add scaling facility for classical device independence and
-     non-groff devices.  Classical troff output had a quasi device
-     independence by scaling the intermediate output to the resolution
-     of the postprocessor device if different from the one specified
-     with `x T', groff have not.  So implement full quasi device
-     indepedence, including the mapping of the strange classical
-     devices to the postprocessor device (seems to be reasonably
-     easy).
-   - The external, global pointer variables are not optimally handled.
-     - The global variables `current_filename',
-       `current_source_filename', and `current_lineno' are only used for
-       error reporting.  So implement a static class `Error'
-       (`::' calls).
-     - The global `device' is the name used during the formatting
-       process; there should be a new variable for the device name used
-       during the postprocessing.
-  - Implement the B-spline drawing `D~' for all graphical devices.
-  - Make `environment' a class with an overflow check for its members
-    and a delete method to get rid of delete_current_env().
-  - Implement the `EnvStack' to use `new' instead of `malloc'.
-  - The class definitions of this document could go into a new file.
-  - The comments in this section should go to a `Changelog' or some
-    `README' file in this directory.
-*/
-
-/*
-  Discussion of the positioning by drawing commands
-
-  There was some confusion about the positioning of the graphical
-  pointer at the printout after having executed a `D' command.
-  The classical troff manual of Osanna & Kernighan specified,
-
-    `The position after a graphical object has been drawn is
-     at its end; for circles and ellipses, the "end" is at the
-     right side.'
-
-  From this, it follows that
-  - all open figures (args, splines, and lines) should position at their
-    final point.
-  - all circles and ellipses should position at their right-most point
-    (as if 2 halves had been drawn).
-  - all closed figures apart from circles and ellipses shouldn't change
-    the position because they return to their origin.
-  - all setting commands should not change position because they do not
-    draw any graphical object.
-
-  In the case of the open figures, this means that the horizontal
-  displacement is the sum of all odd arguments and the vertical offset
-  the sum of all even arguments, called the alternate arguments sum
-  displacement in the following.
-
-  Unfortunately, groff did not implement this simple rule.  The former
-  documentation in groff_out(5) differed from the source code, and
-  neither of them is compatible with the classical rule.
-
-  The former groff_out(5) specified to use the alternative arguments
-  sum displacement for calculating the drawing positioning of
-  non-classical commands, including the `Dt' command (setting-only)
-  and closed polygons.  Applying this to the new groff color commands
-  will lead to disaster.  For their arguments can take large values (>
-  65000).  On low resolution devices, the displacement of such large
-  values will corrupt the display or kill the printer.  So the
-  nonsense specification has come to a natural end anyway.
-
-  The groff source code, however, had no positioning for the
-  setting-only commands (esp. `Dt'), the right-end positioning for
-  outlined circles and ellipses, and the alternative argument sum
-  displacement for all other commands (including filled circles and
-  ellipses).
-
-  The reason why no one seems to have suffered from this mayhem so
-  far is that the graphical objects are usually generated by
-  preprocessors like pic that do not depend on the automatic
-  positioning.  When using the low level `\D' escape sequences or `D'
-  output commands, the strange positionings can be circumvented by
-  absolute positionings or by tricks like `\Z'.
-
-  So doing an exorcism on the strange, incompatible displacements might
-  not harm any existing documents, but will make the usage of the
-  graphical escape sequences and commands natural.
-
-  That's why the rewrite of this file returned to the reasonable,
-  classical specification with its clear end-of-drawing rule that is
-  suitable for all cases.  But a macro STUPID_DRAWING_POSITIONING is
-  provided for testing the funny former behavior.
-
-  The new rule implies the following behavior.
-  - Setting commands (`Dt', `Df', `DF') and polygons (`Dp' and `DP')
-    do not change position now.
-  - Filled circles and ellipses (`DC' and `DE') position at their
-    most right point (outlined ones `Dc' and `De' did this anyway).
-  - As before, all open graphical objects position to their final
-    drawing point (alternate sum of the command arguments).

-Use the same size increases for sum prod int as eqn does.
-
-Perhaps chartype should be renamed.
-
-TeX makes {sub,super}script on a single character with an accent
-into an accent onto the (character with the script). Should we do this?
-
-Implement mark and lineups within scripts, matrices and piles, and accents.
-(Why would this be useful?)
-
-Perhaps push hmotions down through lists to avoid upsetting spacing
-adjustments.
-
-Possibly generate .lf commands during compute_metrics phase.
-
-Consider whether there should be extra space at the side of piles.
-
-Provide scriptstyle displaystyle etc.
-
-Provide a nicer matrix syntax, eg
-matrix ccc {
-a then b then c above
-e then f then g above
-h then i then k
-}
-
-Perhaps generate syntax error messages using the style of gpic.
-
-Wide accents.
-
-More use of \Z.
-
-Extensible square roots.
-
-Vphantom
-
-Smash.
-
-Provide a variant of vec that extends over the length of the accentee.
-
-Support vertical arrow delimiters.
-
-Make the following work:
-.EQ
-delim @@
-.EN
-.EQ @<-@
-some equation

-.SH DESCRIPTION
-This manual page describes the GNU version of
-.BR eqn ,
-which is part of the groff document formatting system.
-.B eqn
-compiles descriptions of equations embedded within
-.B troff
-input files into commands that are understood by
-.BR troff .
-Normally, it should be invoked using the
-.B \-e
-option of
-.BR groff .
-The syntax is quite compatible with Unix eqn.
-The output of GNU
-.B eqn
-cannot be processed with Unix troff;
-it must be processed with GNU troff.
-If no files are given on the command line, the standard input
-will be read.
-A filename of
-.B \-
-will cause the standard input to be read.
-.
-.LP
-.B eqn
-searches for the file
-.B eqnrc
-in the directories given with the
-.B \-M
-option first, then in
-.BR @SYSTEMMACRODIR@ ,
-.BR @LOCALMACRODIR@ ,
-and finally in the standard macro directory
-.BR @MACRODIR@ .
-If it exists,
-.B eqn
-will process it before the other input files.
-The
-.B \-R
-option prevents this.
-.
-.LP
-GNU
-.B eqn
-does not provide the functionality of neqn:
-it does not support low-resolution, typewriter-like devices
-(although it may work adequately for very simple input).
-.
-.
-.SH OPTIONS
-.TP
-.BI \-d xy
-Specify delimiters
-.I x
-and\~\c
-.I y
-for the left and right end, respectively, of in-line equations.
-Any
-.B delim
-statements in the source file overrides this.
-.
-.TP
-.B \-C
-Recognize
-.B .EQ
-and
-.B .EN
-even when followed by a character other than space or newline.
-.TP
-.B \-N
-Don't allow newlines within delimiters.
-This option allows
-.B eqn
-to recover better from missing closing delimiters.
-.
-.TP
-.B \-v
-Print the version number.
-.
-.TP
-.B \-r
-Only one size reduction.
-.
-.TP
-.BI \-m n
-The minimum point-size is\~\c
-.IR n .
-.B eqn
-will not reduce the size of subscripts or superscripts to
-a smaller size than\~\c
-.IR n .
-.
-.TP
-.BI \-T name
-The output is for device
-.IR name .
-The only effect of this is to define a macro
-.I name
-with a value of\~\c
-.BR 1 .
-Typically
-.B eqnrc
-will use this to provide definitions appropriate for the output device.
-The default output device is
-.BR @DEVICE@ .
-.
-.TP
-.BI \-M dir
-Search
-.I dir
-for
-.B eqnrc
-before the default directories.
-.
-.TP
-.B \-R
-Don't load
-.BR eqnrc .
-.
-.TP
-.BI \-f F
-This is equivalent to a
-.BI gfont\  F
-command.
-.
-.TP
-.BI \-s n
-This is equivalent to a
-.BI gsize\  n
-command.
-This option is deprecated.
-.B eqn
-will normally set equations at whatever the current point size
-is when the equation is encountered.
-.
-.TP
-.BI \-p n
-This says that subscripts and superscripts should be
-.I n\~\c
-points smaller than the surrounding text.
-This option is deprecated. 
-Normally
-.B eqn
-makes sets subscripts and superscripts at 70% 
-of the size of the surrounding text.
-.
-.
-.SH USAGE
-Only the differences between GNU
-.B eqn
-and Unix eqn are described here.
-.
-.LP
-Most of the new features of GNU
-.B eqn
-are based on \*(tx.
-There are some references to the differences between \*(tx and GNU
-.B eqn
-below;
-these may safely be ignored if you do not know \*(tx.
-.
-.SS Automatic spacing
-.B eqn
-gives each component of an equation a type, and adjusts the spacing
-between components using that type.
-Possible types are:
-.
-.RS
-.TP \w'punctuation'u+2n
-ordinary
-an ordinary character such as `1' or `\c
-.IR x ';
-.
-.TP
-operator
-a large operator such as
-.ds Su `\s+5\(*S\s0'
-.if \n(.g .if !c\(*S .ds Su the summation operator
-\*(Su;
-.
-.TP
-binary
-a binary operator such as `\(pl';
-.
-.TP
-relation
-a relation such as `=';
-.
-.TP
-opening
-a opening bracket such as `(';
-.
-.TP
-closing
-a closing bracket such as `)';
-.
-.TP
-punctuation
-a punctuation character such as `,';
-.
-.TP
-inner
-a subformula contained within brackets;
-.TP
-suppress
-spacing that suppresses automatic spacing adjustment.
-.RE
-.
-.LP
-Components of an equation get a type in one of two ways.
-.
-.TP
-.BI type\  t\ e
-This yields an equation component that contains\~\c
-.I e
-but that has type\~\c
-.IR t ,
-where
-.I t
-is one of the types mentioned above.
-For example,
-.B times
-is defined as
-.
-.RS
-.IP
-.B
-type "binary" \e(mu
-.RE
-.
-.IP
-The name of the type doesn't have to be quoted, but quoting protects
-from macro expansion.
-.
-.TP
-.BI chartype\  t\ text
-Unquoted groups of characters are split up into individual characters,
-and the type of each character is looked up;
-this changes the type that is stored for each character;
-it says that the characters in
-.I text
-from now on have type\~\c
-.IR t .
-For example,
-.
-.RS
-.IP
-.B
-chartype "punctuation" .,;:
-.RE
-.
-.IP
-would make the characters `.,;:' have type punctuation
-whenever they subsequently appeared in an equation.
-The type\~\c
-.I t
-can also be
-.B letter
-or
-.BR digit ;
-in these cases
-.B chartype
-changes the font type of the characters.
-See the
-.B Fonts
-subsection.
-.
-.SS New primitives
-.TP
-.IB e1\  smallover\  e2
-This is similar to
-.BR over ;
-.B smallover
-reduces the size of
-.I e1
-and
-.IR e2 ;
-it also puts less vertical space between
-.I e1
-or
-.I e2
-and the fraction bar.
-The
-.B over
-primitive corresponds to the \*(tx
-.B \eover
-primitive in display styles;
-.B smallover
-corresponds to
-.B \eover
-in non-display styles.
-.
-.TP
-.BI vcenter\  e
-This vertically centers
-.I e
-about the math axis.
-The math axis is the vertical position about which characters
-such as `\(pl' and `\(mi' are centered; also it is the vertical position
-used for the bar of fractions.
-For example,
-.B sum
-is defined as
-.
-.RS
-.IP
-.B
-{ type "operator" vcenter size +5 \e(*S }
-.RE
-.
-.TP
-.IB e1\  accent\  e2
-This sets
-.I e2
-as an accent over
-.IR e1 .
-.I e2
-is assumed to be at the correct height for a lowercase letter;
-.I e2
-will be moved down according if
-.I e1
-is taller or shorter than a lowercase letter.
-For example,
-.B hat
-is defined as
-.
-.RS
-.IP
-.B
-accent { "^" }
-.RE
-.
-.IP
-.BR dotdot ,
-.BR dot ,
-.BR tilde ,
-.BR vec ,
-and
-.B dyad
-are also defined using the
-.B accent
-primitive.
-.
-.TP
-.IB e1\  uaccent\  e2
-This sets
-.I e2
-as an accent under
-.IR e1 .
-.I e2
-is assumed to be at the correct height for a character without a descender;
-.I e2
-will be moved down if
-.I e1
-has a descender.
-.B utilde
-is pre-defined using
-.B uaccent
-as a tilde accent below the baseline.
-.
-.TP
-.BI split\ \(ts text \(ts
-This has the same effect as simply
-.
-.RS
-.IP
-.I text
-.RE
-.
-.IP
-but
-.I text
-is not subject to macro expansion because it is quoted;
-.I text
-will be split up and the spacing between individual characters
-will be adjusted.
-.
-.TP
-.BI nosplit\  text
-This has the same effect as
-.
-.RS
-.IP
-.BI \(ts text \(ts
-.RE
-.
-.IP
-but because
-.I text
-is not quoted it will be subject to macro expansion;
-.I text
-will not be split up
-and the spacing between individual characters will not be adjusted.
-.
-.TP
-.IB e\  opprime
-This is a variant of
-.B prime
-that acts as an operator on\~\c
-.IR e .
-It produces a different result from
-.B prime
-in a case such as
-.BR A\ opprime\ sub\ 1 :
-with
-.B opprime
-the\~\c
-.B 1
-will be tucked under the prime as a subscript to the\~\c
-.B A
-(as is conventional in mathematical typesetting),
-whereas with
-.B prime
-the\~\c
-.B 1
-will be a subscript to the prime character.
-The precedence of
-.B opprime
-is the same as that of
-.B bar
-and
-.BR under ,
-which is higher than that of everything except
-.B accent
-and
-.BR uaccent .
-In unquoted text a\~\c
-.B '
-that is not the first character will be treated like
-.BR opprime .
-.
-.TP
-.BI special\  text\ e
-This constructs a new object from\~\c
-.I e
-using a
-.BR @g@troff (@MAN1EXT@)
-macro named
-.IR text .
-When the macro is called,
-the string
-.B 0s
-will contain the output for\~\c
-.IR e ,
-and the number registers
-.BR 0w ,
-.BR 0h ,
-.BR 0d ,
-.BR 0skern ,
-and
-.BR 0skew
-will contain the width, height, depth, subscript kern, and skew of\~\c
-.IR e .
-(The
-.I "subscript kern"
-of an object says how much a subscript on that object should be tucked in;
-the
-.I skew
-of an object says how far to the right of the center of the object an
-accent over the object should be placed.)
-The macro must modify
-.B 0s
-so that it will output the desired result with its origin at the current
-point, and increase the current horizontal position by the width
-of the object.
-The number registers must also be modified so that they correspond to the
-result.

-denominator by at least this amount.
-.
-.TP
-.B accent_width
-When
-.B bar
-or
-.B under
-is applied to a single character,
-the line will be this long.
-Normally,
-.B bar
-or
-.B under
-produces a line whose length is the width of the object to which it applies;
-in the case of a single character,
-this tends to produce a line that looks too long.
-.
-.TP
-.B delimiter_factor
-Extensible delimiters produced with the

-Besides the macros mentioned above, the following definitions are available:
-.BR Alpha ,
-.BR Beta ,

-.B Omega
-(this is the same as
-.BR ALPHA ,
-.BR BETA ,
-\&.\|.\|.,
-.BR OMEGA ),
-.B ldots
-(three dots on the base line),
-and
-.BR dollar .
-.
-.SS Fonts
-.B eqn
-normally uses at least two fonts to set an equation:
-an italic font for letters,
-and a roman font for everything else.
-The existing
-.B gfont
-command
-changes the font that is used as the italic font.
-By default this is\~\c
-.BR I .
-The font that is used as the roman font can be changed
-using the new
-.B grfont
-command.
-.
-.TP
-.BI grfont\  f
-Set the roman font to\~\c
-.IR f .
-.
-.LP
-The
-.B italic
-primitive uses the current italic font set by
-.BR gfont ;
-the
-.B roman
-primitive uses the current roman font set by
-.BR grfont .
-There is also a new
-.B gbfont
-command, which changes the font used by the
-.B bold
-primitive.
-If you only use the
-.BR roman ,
-.B italic
-and
-.B bold
-primitives to changes fonts within an equation,
-you can change all the fonts used by your equations
-just by using
-.BR gfont ,
-.B grfont
-and
-.B gbfont
-commands.
-.
-.LP
-You can control which characters are treated as letters
-(and therefore set in italics) by using the
-.B chartype
-command described above.
-A type of
-.B letter
-will cause a character to be set in italic type.
-A type of
-.B digit
-will cause a character to be set in roman type.

-This is grn from the Berkeley ditroff distribution.  It has no
-AT&T code and is therefore freely distributable.
-
-Tim Theisen <tim@cs.wisc.edu>
-
-=====================================================================
-
-This is the modified code for the groff.  It uses the different
-devxxx format that is ascii rather than binary as in the
-Berkeley distribution.  Since groff does not have the \Ds option
-for line drawing (dotted, dashed, etc.), this version includes
-the routines for drawing curves and arcs, so it does not use the
-\D~, \Da nor \Dc.  Although also included in here is a routine
-for drawing the optional gremlin style curves, it is not used
-because the gremlin editor uses the conventional spline
-algorithm.  The Berkeley grn has the choice of different
-stipples.  Here, only different shades of gray will be painted
-depending on the gremlin file.  It is possible to upgrade this at
-a later time.  (Daniel Senderowicz <daniel@synchrods.com> 12/28/99)
-
-=====================================================================
-
-Gremlin produces three types of curves: B-Splines, interpolated
-curves and Bezier.  As the original Berkeley grn, now groff grn
-will honor B-Splines and interpolated curves.  Bezier curves will
-be printed as B-Splines.  (Daniel Senderowicz <daniel@synchrods.com>
-10/04/02)
-
-=====================================================================
-
-It has been further modified by Werner Lemberg <wl@gnu.org> to fit
-better into the groff package.
-
-  . Replaced Makefile with Makefile.sub.
-
-  . Removed dev.h since it is unused.
-
-  . Renamed grn.1 to grn.man; this man page has been extensively
-    revised.
-
-  . Used error() and fatal() from libgroff for all source files.
-
-  . Renamed *.c to *.cpp; updates as needed for C++ (prototypes, proper
-    casts, standard header files etc).  Heavy formatting.
-
-  . main.cpp:
-
-      Using groff's default values instead of DEVDIR, DEFAULTDEV, PRINTER,
-      TYPESETTER, and GREMLIB.
-
-      `res' is now an integer.
-
-      Added `-C' command flag (for compatibility mode) as with other
-      preprocessors.
-
-      Added `-F' and `-v' option (similar to troff).
-
-      Renamed `-L' option to `-M' for consistence.
-
-      Removed `-P' option.
-
-      Using font::load_desc() for scanning DESC files.
-
-      Removed SYSV-specific code.
-
-      Using macro_path.open_file() for getting gremlin graphic files.
-
-      Added usage().

-@g@grn \- groff preprocessor for gremlin files
-.SH SYNOPSIS
-.BR @g@grn
-[
-.B \-Cv
-]
-[
-.BI \-T dev
-]
-[
-.BI \-M dir
-]
-[
-.BI \-F dir
-]
-[
-.IR file\.\.\.\&
-]
-.PP
-It is possible to have whitespace between a command line option and its
-parameter.
-.SH DESCRIPTION
-.I @g@grn
-is a preprocessor for including
-.I gremlin
-pictures in
-.I groff
-input.
-.I @g@grn
-writes to standard output, processing only input lines between two that
-start with
-.B .GS
-and
-.BR .GE.
-Those lines must contain
-.I @g@grn
-commands (see below).
-These commands request a
-.I gremlin
-file, and the picture in that file is
-converted and placed in the
-.I @g@troff
-input stream.
-The
-.B .GS
-request may be followed by a C, L, or R to center, left, or right
-justify the whole
-.I gremlin
-picture (default justification is center).
-If no
-.I file
-is mentioned, the standard input is read.
-At the end of the picture, the position on the page is the bottom of the
-.I gremlin
-picture.
-If the
-.I @g@grn
-entry is ended with
-.B .GF
-instead of
-.BR .GE ,
-the position is left at the top of the picture.
-.PP
-Please note that currently only the \-me macro package has support for
-.BR .GS ,
-.BR .GE ,
-and
-.BR .GF .
-.PP
-The following command-line options are understood:
-.TP
-.BI \-T dev
-Prepare output for printer
-.IR dev .
-The default device is
-.BR @DEVICE@ .
-See
-.BR groff (@MAN1EXT@)
-for acceptable devices.
-.TP
-.BI \-M dir
-Prepend
-.I dir
-to the default search path for
-.I gremlin
-files.
-The default path is (in that order) the current directory, the home
-directory,
-.BR @SYSTEMMACRODIR@ ,
-.BR @LOCALMACRODIR@ ,
-and
-.BR @MACRODIR@ .
-.TP
-.BI \-F dir
-Search
-.I dir
-for subdirectories
-.BI dev name
-.RI ( name
-is the name of the device) for the
-.B DESC
-file before the default font directories
-.BR @LOCALFONTDIR@ ,
-.BR @FONTDIR@ ,
-and
-.BR @LEGACYFONTDIR@ .
-.TP
-.B \-C
-Recognize
-.B .GS
-and
-.B .GE
-(and
-.BR .GF )
-even when followed by a character other than space or newline.
-.\".TP
-.\".B \-s
-.\"This switch causes the picture to be traversed twice:
-.\"The first time, only the interiors of filled polygons (as borderless
-.\"polygons) are printed.
-.\"The second time, the outline is printed as a series of line segments.
-.\"This way, postprocessors that overwrite rather than merge picture elements
-.\"(such as Postscript) can still have text and graphics on a shaded
-.\"background.
-.TP
-.B \-v
-Print the version number.
-.SH GRN COMMANDS
-Each input line between
-.B .GS
-and
-.B .GE
-may have one
-.I @g@grn
-command.
-Commands consist of one or two strings separated by white space, the first
-string being the command and the second its operand.
-Commands may be upper or lower case and abbreviated down to one character.
-.PP
-Commands that affect a picture's environment (those listed before
-.BR default ,
-see below) are only in effect for the current picture:
-The environment is reinitialized to the defaults at the start of the next
-picture.
-The commands are as follows:
-.TP
-.BI 1\  N
-.TQ
-.BI 2\  N
-.TQ
-.BI 3\  N
-.TQ
-.BI 4\  N
-Set
-.IR gremlin 's
-text size number 1 (2, 3, or 4) to
-.I N
-points.
-The default is 12 (16, 24, and 36, respectively).
-.TP
-.BI roman\  f
-.TQ
-.BI italics\  f
-.TQ
-.BI bold\  f
-.TQ
-.BI special\  f
-Set the roman (italics, bold, or special) font to
-.IR @g@troff 's
-font
-.I f
-(either a name or number).
-The default is R (I, B, and S, respectively).
-.TP
-.BI l\  f
-.TQ
-.BI stipple\  f
-Set the stipple font to
-.IR @g@troff 's
-stipple font
-.I f
-(name or number).
-The command
-.B stipple
-may be abbreviated down as far as `st' (to avoid
-confusion with
-.BR special ).
-There is
-.I no
-default for stipples (unless one is set by the default command), and it is
-invalid to include a
-.I gremlin
-picture with polygons without specifying a
-stipple font.
-.TP
-.BI x\  N
-.TQ
-.BI scale\  N
-Magnify the picture (in addition to any default magnification) by
-.IR N ,
-a floating point number larger than zero.
-The command
-.B scale
-may be abbreviated down to `sc'.
-.TP
-.BI narrow\  N
-.TQ
-.BI medium\  N
-.TQ
-.BI thick\  N
-Set the thickness of
-.IR gremlin 's
-narrow (medium and thick, respectively) lines to
-.I N
-times 0.15pt (this value can be changed at compile time).
-The default is 1.0 (3.0 and 5.0, respectively), which corresponds to 0.15pt
-(0.45pt and 0.75pt, respectively).
-A thickness value of zero selects the smallest available line thickness.
-Negative values cause the line thickness to be proportional to the current
-point size.
-.TP
-.BI pointscale\  <off/on>
-Scale text to match the picture.
-Gremlin text is usually printed in the point size specified with the
-commands
-.BR 1 ,
-.BR 2 ,
-.BR 3 ,
-.RB or\~ 4 ,
-regardless of any scaling factors in the picture.
-Setting
-.B pointscale
-will cause the point sizes to scale with the picture (within
-.IR @g@troff 's
-limitations, of course).
-An operand of anything but
-.I off
-will turn text scaling on.
-.TP
-.B default
-Reset the picture environment defaults to the settings in the current
-picture.
-This is meant to be used as a global parameter setting mechanism at the
-beginning of the
-.I @g@troff
-input file, but can be used at any time to reset the
-default settings.
-.TP
-.BI width\  N
-Forces the picture to be
-.I N
-inches wide.
-This overrides any scaling factors present in the same picture.
-.RB ` width
-.IR 0 '
-is ignored.
-.TP
-.BI height\  N
-Forces picture to be
-.I N
-inches high, overriding other scaling factors.
-If both `width' and `height' are specified the tighter constraint will
-determine the scale of the picture.
-.B Height
-and
-.B width
-commands are not saved with a
-.B default
-command.
-They will, however, affect point size scaling if that option is set.
-.TP
-.BI file\  name
-Get picture from
-.I gremlin
-file
-.I name
-located the current directory (or in the library directory; see the
-.B \-M
-option above).
-If two
-.B file
-commands are given, the second one overrides the first.
-If
-.I name
-doesn't exist, an error message is reported and processing continues from
-the
-.B .GE
-line.
-.SH NOTES ABOUT GROFF
-Since
-.I @g@grn
-is a preprocessor, it doesn't know about current indents, point sizes,
-margins, number registers, etc.
-Consequently, no
-.I @g@troff
-input can be placed between the
-.B .GS
-and
-.B .GE
-requests.
-However,
-.I gremlin
-text is now processed by
-.IR @g@troff ,
-so anything legal in a single line of
-.I @g@troff
-input is legal in a line of
-.I gremlin
-text (barring `.' directives at the beginning of a line).
-Thus, it is possible to have equations within a
-.I gremlin
-figure by including in the
-.I gremlin
-file
-.I eqn
-expressions enclosed by previously defined delimiters (e.g.
-.IR $$ ).
-.PP
-When using
-.I @g@grn
-along with other preprocessors, it is best to run
-.I tbl
-before
-.IR @g@grn ,
-.IR pic ,
-and/or
-.I ideal
-to avoid overworking
-.IR tbl .
-.I Eqn
-should always be run last.
-.PP
-A picture is considered an entity, but that doesn't stop
-.I @g@troff
-from trying to break it up if it falls off the end of a page.
-Placing the picture between `keeps' in \-me macros will ensure proper
-placement.
-.PP
-.I @g@grn
-uses
-.IR @g@troff 's 
-number registers
-.B g1
-through
-.B g9
-and sets registers
-.B g1
-and
-.B g2
-to the width and height of the
-.I gremlin
-figure (in device units) before entering the
-.B .GS
-request (this is for those who want to rewrite these macros).
-.SH GREMLIN FILE FORMAT
-There exist two distinct 
-.I gremlin
-file formats, the original format from the
-.I AED
-graphic terminal version, and the
-.I SUN
-or
-.I X11
-version.
-An extension to the
-.IR SUN / X11
-version allowing reference points with negative coordinates is
-.B not
-compatible with the
-.I AED
-version.
-As long as a 
-.I gremlin
-file does not contain negative coordinates, either format will be read
-correctly by either version of
-.I gremlin
-or
-.IR @g@grn .
-The other difference to the
-.IR SUN / X11
-format is the use of names for picture objects (e.g., POLYGON, CURVE)
-instead of numbers.
-Files representing the same picture are shown in Table 1 in each format.

-The second line of the file contains an orientation, and
-.B x

-values for a positioning point, separated by spaces.
-The orientation, either
-.B 0
-or
-.BR 1 ,
-is ignored by the
-.IR SUN / X11
-version.
-.B 0
-means that
-.I gremlin
-will display things in horizontal format (drawing area wider than it is
-tall, with menu across top).
-.B 1
-means that
-.I gremlin
-will display things in vertical format (drawing area taller than it is wide,
-with menu on left side).
-.B x
-and
-.B y
-are floating point values giving a positioning point to be used when this
-file is read into another file.
-The stuff on this line really isn't all that important; a value of ``1 0.00
-0.00'' is suggested.

-After the object type comes a variable number of lines, each specifying a
-point used to display the element.
-Each line contains an x-coordinate and a y-coordinate in floating point
-format, separated by spaces.
-The list of points is terminated by a line containing the string ``-1.0
--1.0''
-.RI ( AED
-version) or a single asterisk, ``*''
-.RI ( SUN / X11
-version).
-.IP \(bu
-After the points comes a line containing two decimal values, giving the
-brush and size for the element.
-The brush determines the style in which things are drawn.
-For vectors, arcs, and curves there are six legal brush values:
-.sp
-.TS
-center, tab(@);
-ncw(0.1i)l.
-1 \(mi@@thin dotted lines
-2 \(mi@@thin dot-dashed lines
-3 \(mi@@thick solid lines
-4 \(mi@@thin dashed lines
-5 \(mi@@thin solid lines
-6 \(mi@@medium solid lines
-.TE
-.sp
-For polygons, one more value, 0, is legal.
-It specifies a polygon with an invisible border.
-For text, the brush selects a font as follows:
-.sp
-.TS
-center, tab(@);
-ncw(0.1i)l.
-1 \(mi@@roman (R font in groff)
-2 \(mi@@italics (I font in groff)
-3 \(mi@@bold (B font in groff)
-4 \(mi@@special (S font in groff)
-.TE
-.sp
-If you're using
-.I @g@grn
-to run your pictures through
-.IR groff ,
-the font is really just a starting font:
-The text string can contain formatting sequences like
-``\efI''
-or
-``\ed''
-which may change the font (as well as do many other things).
-For text, the size field is a decimal value between 1 and 4.
-It selects the size of the font in which the text will be drawn.
-For polygons, this size field is interpreted as a stipple number to fill the
-polygon with.
-The number is used to index into a stipple font at print time.
-.IP \(bu
-The last line of each element contains a decimal number and a string of
-characters, separated by a single space.
-The number is a count of the number of characters in the string.
-This information is only used for text elements, and contains the text
-string.
-There can be spaces inside the text.
-For arcs, curves, and vectors, this line of the element contains the string
-``0''.
-.SH NOTES ON COORDINATES
-.I gremlin
-was designed for
-.IR AED s,
-and its coordinates reflect the
-.I AED
-coordinate space.
-For vertical pictures, x-values range 116 to 511, and y-values from 0 to
-483.
-For horizontal pictures, x-values range from 0 to 511 and y-values range
-from 0 to 367.
-Although you needn't absolutely stick to this range, you'll get best results
-if you at least stay in this vicinity.
-Also, point lists are terminated by a point of (-1, -1), so you shouldn't
-ever use negative coordinates.
-.I gremlin
-writes out coordinates using format ``%f1.2''; it's probably a good idea to
-use the same format if you want to modify the
-.I @g@grn
-code.
-.SH NOTES ON SUN/X11 COORDINATES
-There is no longer a restriction on the range of coordinates used to create
-objects in the
-.IR SUN / X11
-version of
-.IR gremlin .
-However, files with negative coordinates
-.B will
-cause problems if displayed on the
-.IR AED .

- *
- * This file contains the main and file system dependent routines for

- * with a `default' command and are further overridden by commands in the
- * input.
- *
- * Inside the GS and GE, commands are accepted to reconfigure the picture. 
- * At most one command may reside on each line, and each command is followed
- * by a parameter separated by white space.  The commands are as follows,
- * and may be abbreviated down to one character (with exception of `scale'
- * and `stipple' down to "sc" and "st") and may be upper or lower case.
- *
- *                        default  -  Make all settings in the current
- *                                    .GS/.GE the global defaults.  Height,

- *                                    integer point size).
- *  roman, italics, bold, special  -  Set gremlin's fonts to any other troff
- *                                    font (one or two characters).
- *                     stipple, l  -  Use a stipple font for polygons.  Arg

- *                     pointscale  -  Turn on scaling point sizes to match

-In troff mode, dotted and dashed splines.
-
-Make DELIMITED have type lstr; this would allow us to give better
-error messages for problems within the body of for and if constructs.
-
-In troff mode without -x, fake \D't' with .ps commands.
-
-Perhaps an option to set command char.
-
-Add an output class for dumb line printers. It wouldn't be pretty but
-it would be better than nothing. Integrate it with texinfo.  Useful
-for groff -Tascii as well.
-
-Option to allow better positioning of arrowheads on arcs.
-
-Perhaps add PostScript output mode.
-
-Change the interface to the output class so that output devices have
-the opportunity to handle arrowheads themselves.
-
-Consider whether the line thickness should scale.
-
-Consider whether the test in a for loop should be fuzzy (as it
-apparently is in grap).
-
-Possibly change fillval so that zero is black.
-
-Provide a way of getting text blocks (positioned with `.in' rather
-than \h), into pic.  Should be possible to use block of diverted text
-in pic.  Possibly something similar to T{ and T} in tbl.
-
-Option to provide macro backtraces.
-
-Have a path that is searched by `copy' statement.  Set by environment
-variable or command line option.

-@g@pic \- compile pictures for troff or TeX

-\&.\|.\|.\&

-.
-.SH DESCRIPTION
-.
-This manual page describes the GNU version of
-.BR pic ,
-which is part of the groff document formatting system.
-.B pic
-compiles descriptions of pictures embedded within
-.B troff
-or \*(tx input files into commands that are understood by \*(tx or
-.BR troff .
-Each picture starts with a line beginning with
-.B .PS
-and ends with a line beginning with
-.BR .PE .
-Anything outside of
-.B .PS
-and
-.B .PE
-is passed through without change.
-.LP
-It is the user's responsibility to provide appropriate definitions of the
-.B PS
-and
-.B PE
-macros.
-When the macro package being used does not supply such definitions
-(for example, old versions of \-ms),
-appropriate definitions can be obtained with
-.BR \-mpic :
-These will center each picture.
-.
-.
-.SH OPTIONS
-.
-Options that do not take arguments may be grouped behind a single
-.BR \- .
-The special option
-.B \-\^\-
-can be used to mark the end of the options.
-A filename of
-.B \-
-refers to the standard input.
-.
-.TP
-.B \-C
-Recognize
-.B .PS
-and
-.B .PE
-even when followed by a character other than space or newline.
-.
-.TP
-.B \-S
-Safer mode; do not execute
-.B sh
-commands.
-This can be useful when operating on untrustworthy input.
-(enabled by default)
-.
-.TP
-.B \-U
-Unsafe mode; revert the default option
-.BR \-S .
-.
-.TP
-.B \-n
-Don't use the groff extensions to the troff drawing commands.
-You should use this if you are using a postprocessor that doesn't support
-these extensions.
-The extensions are described in
-.BR groff_out (@MAN5EXT@).
-The
-.B \-n
-option also causes
-.B pic
-not to use zero-length lines to draw dots in troff mode.
-.
-.TP
-.B \-t
-\*(tx mode.
-.
-.TP
-.B \-c
-Be more compatible with
-.BR tpic .
-Implies
-.BR \-t .
-Lines beginning with
-.B \e
-are not passed through transparently.
-Lines beginning with
-.B .
-are passed through with the initial
-.B .
-changed to
-.BR \e .
-A line beginning with
-.B .ps
-is given special treatment:
-it takes an optional integer argument specifying
-the line thickness (pen size) in milliinches;
-a missing argument restores the previous line thickness;
-the default line thickness is 8 milliinches.
-The line thickness thus specified takes effect only
-when a non-negative line thickness has not been
-specified by use of the
-.B thickness
-attribute or by setting the
-.B linethick
-variable.
-.
-.TP
-.B \-v
-Print the version number.
-.
-.TP
-.B \-z
-In \*(tx mode draw dots using zero-length lines.
-.
-.LP
-The following options supported by other versions of
-.B pic
-are ignored:
-.
-.TP
-.B \-D

-.SH USAGE
-.
-This section describes only the differences between GNU
-.B pic
-and the original version of
-.BR pic .
-Many of these differences also apply to newer versions of Unix
-.BR pic .
-A complete documentation is available in the file
-.LP
-.RS
-.B @DOCDIR@/pic.ms
-.RE
-.
-.SS \*(tx mode
-.
-\*(tx mode is enabled by the
-.B \-t
-option.
-In \*(tx mode,
-.B pic
-will define a vbox called
-.B \egraph
-for each picture.
-Use the
-.B figname
-command to change the name of the vbox.
-You must yourself print that vbox using, for example, the command
-.RS
-.LP
-.B
-\ecenterline{\ebox\egraph}
-.RE
-.LP
-Actually, since the vbox has a height of zero (it is defined with
-\evtop) this will produce slightly more vertical space above the
-picture than below it;
-.RS
-.LP
-.B
-\ecenterline{\eraise 1em\ebox\egraph}
-.RE
-.LP
-would avoid this.
-.LP
-To make the vbox having a positive height and a depth of zero
-(as used e.g.\& by \*(lx's
-.BR \%graphics.sty ),
-define the following macro in your document:
-.RS
-.LP
-.B \edef\egpicbox#1{%
-.br
-.B "   \evbox{\eunvbox\ecsname #1\eendcsname\ekern 0pt}}"
-.RE
-.LP
-Now you can simply say
-.B \egpicbox{graph}
-instead of \ebox\egraph.
-.LP
-You must use a \*(tx driver that supports the
-.B tpic
-specials, version 2.
-.LP
-Lines beginning with
-.B \e
-are passed through transparently; a
-.B %
-is added to the end of the line to avoid unwanted spaces.
-You can safely use this feature to change fonts or to
-change the value of
-.BR \ebaselineskip .
-Anything else may well produce undesirable results; use at your own risk.
-Lines beginning with a period are not given any special treatment.

-.LP
-String comparison expressions must be parenthesised in some contexts
-to avoid ambiguity.
-.
-.SS Other Changes
-.
-A bare expression,
-.IR expr ,
-is acceptable as an attribute;
-it is equivalent to
-.IR dir\ expr ,
-where
-.I dir
-is the current direction.
-For example
-.LP
-.RS
-.B line 2i
-.RE
-.LP
-means draw a line 2\ inches long in the current direction.
-The `i' (or `I') character is ignored; to use another measurement unit,
-set the
-.I scale
-variable to an appropriate value.
-.
-.LP
-The maximum width and height of the picture are taken from the variables
-.B maxpswid
-and
-.BR maxpsht .
-Initially these have values 8.5 and 11.
-.
-.LP
-Scientific notation is allowed for numbers.
-For example
-.RS
-.LP
-.B
-x = 5e\-2
-.RE
-.
-.LP
-Text attributes can be compounded.
-For example,
-.RS
-.LP
-.B
-"foo" above ljust
-.RE
-.LP
-is valid.
-.
-.LP
-There is no limit to the depth to which blocks can be examined.
-For example,
-.RS
-.LP
-.B
-[A: [B: [C: box ]]] with .A.B.C.sw at 1,2
-.br
-.B
-circle at last [\^].A.B.C
-.RE
-.LP
-is acceptable.
-.
-.LP
-Arcs now have compass points
-determined by the circle of which the arc is a part.
-.
-.LP
-Circles, ellipses, and arcs can be dotted or dashed.
-In \*(tx mode splines can be dotted or dashed also.
-.
-.LP
-Boxes can have rounded corners.
-The
-.B rad
-attribute specifies the radius of the quarter-circles at each corner.
-If no
-.B rad
-or
-.B diam
-attribute is given, a radius of
-.B boxrad
-is used.
-Initially,
-.B boxrad
-has a value of\ 0.
-A box with rounded corners can be dotted or dashed.
-.
-.LP
-The
-.B .PS
-line can have a second argument specifying a maximum height for
-the picture.
-If the width of zero is specified the width will be ignored in computing
-the scaling factor for the picture.
-Note that GNU
-.B pic
-will always scale a picture by the same amount vertically as well as
-horizontally.
-This is different from the
-.SM DWB
-2.0
-.B pic
-which may scale a picture by a different amount vertically than
-horizontally if a height is specified.
-.
-.LP
-Each text object has an invisible box associated with it.
-The compass points of a text object are determined by this box.
-The implicit motion associated with the object is also determined
-by this box.
-The dimensions of this box are taken from the width and height attributes;
-if the width attribute is not supplied then the width will be taken to be
-.BR textwid ;
-if the height attribute is not supplied then the height will be taken to be
-the number of text strings associated with the object
-times
-.BR textht .
-Initially
-.B textwid
-and
-.B textht
-have a value of 0.
-.
-.LP
-In (almost all) places where a quoted text string can be used,
-an expression of the form
-.IP
-.BI sprintf(\(ts format \(ts,\  arg ,\fR.\|.\|.\fB)
-.LP
-can also be used;
-this will produce the arguments formatted according to
-.IR format ,
-which should be a string as described in
-.BR printf (3)
-appropriate for the number of arguments supplied.
-.
-.LP
-The thickness of the lines used to draw objects is controlled by the
-.B linethick
-variable.
-This gives the thickness of lines in points.
-A negative value means use the default thickness:
-in \*(tx output mode, this means use a thickness of 8 milliinches;
-in \*(tx output mode with the
-.B -c
-option, this means use the line thickness specified by
-.B .ps
-lines;
-in troff output mode, this means use a thickness proportional
-to the pointsize.
-A zero value means draw the thinnest possible line supported by
-the output device.
-Initially it has a value of -1.
-There is also a
-.BR thick [ ness ]
-attribute.
-For example,
-.RS
-.LP
-.B circle thickness 1.5
-.RE
-.LP
-would draw a circle using a line with a thickness of 1.5 points.
-The thickness of lines is not affected by the
-value of the
-.B scale
-variable, nor by the width or height given in the
-.B .PS
-line.
-.
-.LP
-Boxes (including boxes with rounded corners),
-circles and ellipses can be filled by giving them an attribute of
-.BR fill [ ed ].
-This takes an optional argument of an expression with a value between
-0 and 1; 0 will fill it with white, 1 with black, values in between
-with a proportionally gray shade.
-A value greater than 1 can also be used:
-this means fill with the
-shade of gray that is currently being used for text and lines.
-Normally this will be black, but output devices may provide
-a mechanism for changing this.
-Without an argument, then the value of the variable
-.B fillval
-will be used.
-Initially this has a value of 0.5.
-The invisible attribute does not affect the filling of objects.
-Any text associated with a filled object will be added after the
-object has been filled, so that the text will not be obscured
-by the filling.
-.
-.LP
-Three additional modifiers are available to specify colored objects:
-.BR outline [ d ]
-sets the color of the outline,
-.B shaded
-the fill color, and
-.B colo\fR[\fPu\fR]\fPr\fR[\fPed\fR]
-sets both.
-All three keywords expect a suffix specifying the color, for example
-.RS
-.LP
-.B circle shaded """green""" outline """black"""
-.RE
-.LP
-Currently, color support isn't available in \*(tx mode.
-Predefined color names for
-.B groff
-are in the device macro files, for example
-.BR ps.tmac ;
-additional colors can be defined with the
-.B .defcolor
-request (see the manual page of
-.BR @g@troff (@MAN1EXT@)
-for more details).
-.LP
-To change the name of the vbox in \*(tx mode, set the pseudo-variable
-.B figname
-(which is actually a specially parsed command) within a picture.
-Example:
-.RS
-.LP
-.B .PS
-.br
-.B figname = foobar;
-.br
-.B ...
-.br
-.B .PE
-.RE
-.LP
-The picture is then available in the box
-.BR \efoobar .
-.LP
-.B pic
-assumes that at the beginning of a picture both glyph and fill color are
-set to the default value.
-.
-.LP
-Arrow heads will be drawn as solid triangles if the variable
-.B arrowhead
-is non-zero and either \*(tx mode is enabled or the
-.B \-n
-option has not been given.
-Initially
-.B arrowhead
-has a value of\ 1.
-Note that solid arrow heads are always filled with the current outline
-color.
-.
-.LP
-The troff output of
-.B pic
-is device-independent.
-The
-.B \-T
-option is therefore redundant.
-All numbers are taken to be in inches; numbers are never interpreted
-to be in troff machine units.
-.
-.LP
-Objects can have an
-.B aligned
-attribute.
-This will only work if the postprocessor is
-.BR grops .
-Any text associated with an object having the
-.B aligned
-attribute will be rotated about the center of the object
-so that it is aligned in the direction from the start point
-to the end point of the object.
-Note that this attribute will have no effect for objects whose start and
-end points are coincident.
-.
-.LP
-In places where
-.IB n th
-is allowed
-.BI ` expr 'th
-is also allowed.
-Note that
-.B 'th
-is a single token: no space is allowed between the
-.B '
-and the
-.BR th .
-For example,
-.IP

-.nf
-for i = 1 to 4 do {

-inline references
-
-Some sort of macro/subroutine that can cover several references.
-
-move-punctuation should ignore multiple punctuation characters.
-
-Make the index files machine independent.
-
-Allow search keys to be negated (with !) to indicate that the
-reference should not contain the key.  Ignore negated keys during
-indexed searching.
-
-Provide an option with lkbib and lookbib that prints the location
-(filename, position) of each reference.  Need to map filename_id's
-back to filenames.
-
-Rename join-authors to join-fields.  Have a separate label-join-fields
-command used by @ and #.
-
-Have some sort of quantifier: eg $.n#A means execute `$.n' for each
-instance of an A field, setting $ to that field, and then join the
-results using the join-authors command.
-
-no-text-in-bracket command which says not to allow post_text and
-pre_text when the [] flags has been given. Useful for superscripted
-footnotes.
-
-Make it possible to translate - to \(en in page ranges.
-
-Trim eign a bit.
-
-In indexed searching discard all numeric keys except dates.
-
-Allow `\ ' to separate article from first word.
-
-%also
-
-Option automatically to supply [] flags in every reference.
-
-See if we can avoid requiring a comma before jr. and so on
-in find_last_name().
-
-Cache sortified authors in authors string during tentative evaluation of
-label specification.
-
-Possibly don't allow * and % expressions in the first part of ?:, | or
-& expressions.
-
-Handle better the case where <> occurs inside functions and in the
-first operand of ~. Or perhaps implement <> using some magic character
-in the string.
-
-Should special treatment be given to lines beginning with . in
-references?  (Unix refer seems to treat them like `%').
-
-Add global flag to control whether all files should be stat-ed after
-loading, and whether they should be stat-ed before each search.
-Perhaps make this dependent on the number of files there are.
-
-Option to truncate keys to truncate_len in linear searching.
-
-Allow multiple -f options in indxbib.
-
-In indxbib, possibly store common words rather than common words
-filename.  In this case store only words that are actually present in
-the file.
-
-Perhaps we should put out an obnoxious copyright message when lookbib
-starts up.
-
-Provide an option that writes a file containing just the references
-actually used.  Useful if you want to distribute a document.
-
-Have a magic token such that
-%A <sort stuff><magic token><print stuff>
-will print as though it were
-%A <print stuff>
-but sort as though it were
-%A <sort stuff>
-Do we need this if we can specify author alternatives for sorting?
-No, provided we have separate alternatives for @.
-
-In consider_authors when last names are ambiguous we might be able to
-use just the first name and not Jr. bit. Or we might be able to
-abbreviate the author.
-
-It ought to be possible to specify an alternative field to sort on
-instead of date. (ie if there's a field giving the type of document --
-these references should sort after any years)
-
-Provide a way to execute a command using a command-line option.
-
-Option to set the label-spec as a command-line option (-L).
-
-Command to to specify which fields can occur multiple times:
-multiple AE
-
-Command to specify how various fields sort:
-aort-as-name A
-sort-as-date D
-sort-as-title T
-sort-as-other O
-
-Command to specify which fields are author fields:
-# if we don't have A use field Q
-author-fields AQ
-
-Commands to set properties of tokens.
-sortify-token \(ae ae
-uppercase-token \[ae] \[AE]
-
-Command to set the names of months:
-months january february march april may ...
-
-Perhaps provide some sort of macro capability:
-# perhaps a macro capability
-defmacro foo
-annotation-field $1
-endef
-
-Command to control strings used in capitalization
-capitalize-start \s+2
-capitalize-end \s-2
-(perhaps make these arguments to the capitalize command.)

-.SH DESCRIPTION
-This file documents the GNU version of
-.BR refer ,
-which is part of the groff document formatting system.
-.B refer
-copies the contents of
-.IR filename \|.\|.\|.\&
-to the standard output,
-except that lines between
-.B .[
-and
-.B .]\&
-are interpreted as citations,
-and lines between
-.B .R1
-and
-.B .R2
-are interpreted as commands about how citations are to be processed.
-.
-.LP
-Each citation specifies a reference.
-The citation can specify a reference that is contained in
-a bibliographic database by giving a set of keywords
-that only that reference contains.
-Alternatively it can specify a reference by supplying a database
-record in the citation.
-A combination of these alternatives is also possible.
-.
-.LP
-For each citation,
-.B refer
-can produce a mark in the text.
-This mark consists of some label which can be separated from
-the text and from other labels in various ways.
-For each reference it also outputs
-.B groff
-commands that can be used by a macro package to produce a formatted
-reference for each citation.
-The output of
-.B refer
-must therefore be processed using a suitable macro package.
-The
-.B \-ms
-and
-.B \-me
-macros are both suitable.
-The commands to format a citation's reference can be output immediately after
-the citation,
-or the references may be accumulated,
-and the commands output at some later point.
-If the references are accumulated, then multiple citations of the same
-reference will produce a single formatted reference.
-.
-.LP
-The interpretation of lines between
-.B .R1
-and
-.B .R2
-as commands is a new feature of GNU
-.BR refer .
-Documents making use of this feature can still be processed by
-Unix refer just by adding the lines
-.
-.RS
-.LP
-.nf
-.ft B
-\&.de R1
-\&.ig R2
-\&..
-.ft
-.fi
-.RE
-.
-to the beginning of the document.
-This will cause
-.B troff
-to ignore everything between
-.B .R1
-and
-.BR .R2 .
-The effect of some commands can also be achieved by options.
-These options are supported mainly for compatibility with Unix refer.
-It is usually more convenient to use commands.
-.
-.LP
-.B refer
-generates
-.B .lf
-lines so that filenames and line numbers in messages produced
-by commands that read
-.B refer
-output will be correct;
-it also interprets lines beginning with
-.B .lf
-so that filenames and line numbers in the messages and
-.B .lf
-lines that it produces will be accurate even if the input has been
-preprocessed by a command such as
-.BR @g@soelim (@MAN1EXT@).
-.
-.
-.

-.SH USAGE
-.
-.
-.SS Bibliographic databases
-The bibliographic database is a text file consisting of records
-separated by one or more blank lines.
-Within each record fields start with a
-.B %
-at the beginning of a line.
-Each field has a one character name that immediately follows the
-.BR % .
-It is best to use only upper and lower case letters for the names
-of fields.
-The name of the field should be followed by exactly one space,
-and then by the contents of the field.
-Empty fields are ignored.
-The conventional meaning of each field is as follows:
-.
-.TP
-.B A
-The name of an author.
-If the name contains a title such as
-.B Jr.\&
-at the end,
-it should be separated from the last name by a comma.
-There can be multiple occurrences of the
-.B A
-field.
-The order is significant.
-It is a good idea always to supply an
-.B A
-field or a
-.B Q
-field.
-.
-.TP
-.B B
-For an article that is part of a book, the title of the book.
-.
-.TP
-.B C
-The place (city) of publication.
-.
-.TP
-.B D
-The date of publication.
-The year should be specified in full.
-If the month is specified, the name rather than the number of the month
-should be used, but only the first three letters are required.
-It is a good idea always to supply a
-.B D
-field;
-if the date is unknown, a value such as
-.B in press
-or
-.B unknown
-can be used.
-.
-.TP
-.B E
-For an article that is part of a book, the name of an editor of the book.
-Where the work has editors and no authors,
-the names of the editors should be given as
-.B A
-fields and
-.B ,\ (ed)
-or
-.B ,\ (eds)
-should be appended to the last author.
-.
-.TP
-.B G
-US Government ordering number.
-.
-.TP
-.B I
-The publisher (issuer).
-.
-.TP
-.B J
-For an article in a journal, the name of the journal.
-.
-.TP
-.B K
-Keywords to be used for searching.
-.
-.TP
-.B L
-Label.
-.
-.TP
-.B N
-Journal issue number.
-.
-.TP
-.B O
-Other information.
-This is usually printed at the end of the reference.
-.
-.TP
-.B P
-Page number.
-A range of pages can be specified as
-.IB m \- n\fR.
-.
-.TP
-.B Q
-The name of the author, if the author is not a person.
-This will only be used if there are no
-.B A
-fields.
-There can only be one
-.B Q
-field.
-.
-.TP
-.B R
-Technical report number.
-.
-.TP
-.B S
-Series name.
-.
-.TP
-.B T
-Title.
-For an article in a book or journal,
-this should be the title of the article.
-.
-.TP
-.B V
-Volume number of the journal or book.
-.
-.TP
-.B X
-Annotation.
-.
-.LP
-For all fields except
-.B A
-and
-.BR E ,
-if there is more than one occurrence of a particular field in a record,
-only the last such field will be used.
-.
-.LP
-If accent strings are used, they should follow the character to be accented.
-This means that the
-.B AM
-macro must be used with the
-.B \-ms
-macros.
-Accent strings should not be quoted:
-use one
-.B \e
-rather than two.
-.
-.
-.SS Citations
-The format of a citation is
-.
-.RS
-.BI .[ opening-text
-.br
-.I "flags keywords"
-.br
-.I fields
-.br
-.BI .] closing-text
-.RE
-.
-.LP
-The
-.IR opening-text ,
-.IR closing-text
-and
-.I flags
-components are optional.
-Only one of the
-.I keywords
-and
-.I fields
-components need be specified.
-.
-.LP
-The
-.I keywords
-component says to search the bibliographic databases for a reference
-that contains all the words in
-.IR keywords .
-It is an error if more than one reference if found.
-.
-.LP
-The
-.I fields
-components specifies additional fields to replace or supplement
-those specified in the reference.
-When references are being accumulated and the
-.I keywords
-component is non-empty,
-then additional fields should be specified only on the first
-occasion that a particular reference is cited,
-and will apply to all citations of that reference.
-.
-.LP
-The
-.I opening-text
-and
-.I closing-text
-component specifies strings to be used to bracket the label instead
-of the strings specified in the
-.B bracket-label
-command.
-If either of these components is non-empty,
-the strings specified in the
-.B bracket-label
-command will not be used;
-this behaviour can be altered using the
-.B [
-and
-.B ]
-flags.
-Note that leading and trailing spaces are significant for these components.
-.
-.LP
-The
-.I flags
-component is a list of
-non-alphanumeric characters each of which modifies the treatment
-of this particular citation.
-Unix refer will treat these flags as part of the keywords and
-so will ignore them since they are non-alphanumeric.
-The following flags are currently recognized:
-.
-.TP
-.B #
-This says to use the label specified by the
-.B short-label
-command,
-instead of that specified by the
-.B label
-command.
-If no short label has been specified, the normal label will be used.
-Typically the short label is used with author-date labels
-and consists of only the date and possibly a disambiguating letter;
-the
-.B #
-is supposed to be suggestive of a numeric type of label.
-.
-.TP
-.B [
-Precede
-.I opening-text
-with the first string specified in the
-.B bracket-label
-command.
-.
-.TP
-.B ]
-Follow
-.I closing-text
-with the second string specified in the
-.B bracket-label
-command.
-.
-.LP
-One advantages of using the
-.B [
-and
-.B ]
-flags rather than including the brackets in
-.I opening-text
-and
-.I closing-text
-is that
-you can change the style of bracket used in the document just by changing the
-.B bracket-label
-command.
-Another advantage is that sorting and merging of citations
-will not necessarily be inhibited if the flags are used.
-.
-.LP
-If a label is to be inserted into the text,
-it will be attached to the line preceding the
-.B .[
-line.
-If there is no such line, then an extra line will be inserted before the
-.B .[
-line and a warning will be given.
-.
-.LP
-There is no special notation for making a citation to multiple references.
-Just use a sequence of citations, one for each reference.
-Don't put anything between the citations.
-The labels for all the citations will be attached to the line preceding
-the first citation.
-The labels may also be sorted or merged.
-See the description of the
-.B <>
-label expression, and of the
-.B sort-adjacent-labels
-and
-.B abbreviate-label-ranges
-command.
-A label will not be merged if its citation has a non-empty
-.I opening-text
-or
-.IR closing-text .
-However, the labels for a citation using the
-.B ]
-flag and without any
-.I closing-text
-immediately followed by a citation using the
-.B [
-flag and without any
-.I opening-text
-may be sorted and merged
-even though the first citation's
-.I opening-text
-or the second citation's
-.I closing-text
-is non-empty.
-(If you wish to prevent this just make the first citation's
-.I closing-text
-.BR \e& .)
-.
-.
-.SS Commands
-Commands are contained between lines starting with
-.B .R1
-and
-.BR .R2 .
-Recognition of these lines can be prevented by the
-.B \-R
-option.
-When a
-.B .R1
-line is recognized any accumulated references are flushed out.
-Neither
-.B .R1
-nor
-.B .R2
-lines,
-nor anything between them
-is output.
-.
-.LP
-Commands are separated by newlines or
-.BR ; s.
-.B #
-introduces a comment that extends to the end of the line
-(but does not conceal the newline).
-Each command is broken up into words.
-Words are separated by spaces or tabs.
-A word that begins with
-.B \(ts
-extends to the next
-.B \(ts
-that is not followed by another
-.BR \(ts .
-If there is no such
-.B \(ts
-the word extends to the end of the line.
-Pairs of
-.B \(ts
-in a word beginning with
-.B \(ts
-collapse to a single
-.BR \(ts .
-Neither
-.B #
-nor
-.B ;
-are recognized inside
-.BR \(ts s.
-A line can be continued by ending it with
-.BR \e ;
-this works everywhere except after a
-.BR # .
-.
-.LP
-.ds n \fR*
-Each command
-.I name
-that is marked with \*n has an associated negative command
-.BI no- name
-that undoes the effect of
-.IR name .
-For example, the
-.B no-sort
-command specifies that references should not be sorted.
-The negative commands take no arguments.
-.
-.LP
-In the following description each argument must be a single word;
-.I field
-is used for a single upper or lower case letter naming a field;
-.I fields
-is used for a sequence of such letters;
-.I m
-and
-.I n
-are used for a non-negative numbers;
-.I string
-is used for an arbitrary string;
-.I filename
-is used for the name of a file.
-.
-.Tp \w'\fBabbreviate-label-ranges'u+2n
-.BI abbreviate\*n\  fields\ string1\ string2\ string3\ string4
-Abbreviate the first names of
-.IR fields .
-An initial letter will be separated from another initial letter by
-.IR string1 ,
-from the last name by
-.IR string2 ,
-and from anything else
-(such as a
-.B von
-or
-.BR de )
-by
-.IR string3 .
-These default to a period followed by a space.
-In a hyphenated first name,
-the initial of the first part of the name will be separated from the hyphen by
-.IR string4 ;
-this defaults to a period.
-No attempt is made to handle any ambiguities that might
-result from abbreviation.
-Names are abbreviated before sorting and before
-label construction.
-.
-.TP
-.BI abbreviate-label-ranges\*n\  string
-Three or more adjacent labels that refer to consecutive references
-will be abbreviated to a label consisting
-of the first label, followed by
-.I string
-followed by the last label.
-This is mainly useful with numeric labels.
-If
-.I string
-is omitted it defaults to
-.BR \- .
-.
-.TP
-.B accumulate\*n
-Accumulate references instead of writing out each reference
-as it is encountered.
-Accumulated references will be written out whenever a reference
-of the form
-.
-.RS

-.
-.TP
-.BI date-as-label\*n\  string
-.I string
-is a label expression that specifies a string with which to replace the
-.B D
-field after constructing the label.
-See the
-.B "Label expressions"
-subsection for a description of label expressions.
-This command is useful if you do not want explicit labels in the
-reference list, but instead want to handle any necessary
-disambiguation by qualifying the date in some way.
-The label used in the text would typically be some combination of the
-author and date.
-In most cases you should also use the
-.B no-label-in-reference
-command.
-For example,
-.
-.RS
-.IP
-.B "date-as-label D.+yD.y%a*D.-y"
-.
-.LP
-would attach a disambiguating letter to the year part of the
-.B D
-field in the reference.
-.RE
-.
-.TP
-.B default-database\*n
-The default database should be searched.
-This is the default behaviour, so the negative version of

-.B refer
-determines whether the default database should be searched
-on the first occasion that it needs to do a search.
-Thus a
-.B no-default-database
-command must be given before then,
-in order to be effective.
-.
-.TP
-.BI discard\*n\  fields
-When the reference is read,

-authors will be replaced by
-.I string
-provided that
-.IR t \|\-\| u
-is not less than

-.RE
-.
-.TP
-.BI include\  filename
-Include

-how many such fields should be reversed.
-If no number is given for a field, all such fields will be reversed.
-.
-.TP
-.BI search-ignore\*n\  fields
-While searching for keys in databases for which no index exists,
-ignore the contents of
-.IR fields .
-Initially, fields
-.B XYZ
-are ignored.
-.
-.TP
-.BI search-truncate\*n\  n
-Only require the first
-.I n
-characters of keys to be given.
-In effect when searching for a given key
-words in the database are truncated to the maximum of
-.I n
-and the length of the key.
-Initially
-.I n
-is\ 6.
-.
-.TP
-.BI short-label\*n\  string
-.I string
-is a label expression that specifies an alternative (usually shorter)
-style of label.
-This is used when the
-.B #
-flag is given in the citation.
-When using author-date style labels, the identity of the author
-or authors is sometimes clear from the context, and so it
-may be desirable to omit the author or authors from the label.
-The
-.B short-label
-command will typically be used to specify a label containing just
-a date and possibly a disambiguating letter.
-.
-.TP
-.BI sort\*n\  string
-Sort references according to
-.BR string .
-References will automatically be accumulated.
-.I string
-should be a list of field names, each followed by a number,
-indicating how many fields with the name should be used for sorting.
-.B +
-can be used to indicate that all the fields with the name should be used.
-Also
-.B .\&
-can be used to indicate the references should be sorted using the
-(tentative) label.
-(The
-.B "Label expressions"
-subsection describes the concept of a tentative label.)
-.
-.TP
-.B sort-adjacent-labels\*n
-Sort labels that are adjacent in the text according to their
-position in the reference list.
-This command should usually be given if the
-.B abbreviate-label-ranges
-command has been given,
-or if the label expression contains a
-.B <>
-expression.
-This will have no effect unless references are being accumulated.
-.
-.
-.SS Label expressions
-.
-.LP
-Label expressions can be evaluated both normally and tentatively.
-The result of normal evaluation is used for output.
-The result of tentative evaluation, called the
-.IR "tentative label" ,
-is used to gather the information
-that normal evaluation needs to disambiguate the label.
-Label expressions specified by the
-.B date-as-label
-and
-.B short-label
-commands are not evaluated tentatively.
-Normal and tentative evaluation are the same for all types
-of expression other than
-.BR @ ,
-.BR * ,
-and
-.B %
-expressions.
-The description below applies to normal evaluation,
-except where otherwise specified.
-.
-.TP
-.I field
-.TQ
-.I field\ n
-The
-.IR n -th
-part of
-.IR field .
-If
-.I n
-is omitted, it defaults to\ 1.
-.
-.TP
-.BI ' string '
-The characters in
-.I string
-literally.
-.
-.TP
-.B @
-All the authors joined as specified by the
-.B join-authors
-command.
-The whole of each author's name will be used.
-However, if the references are sorted by author
-(that is the sort specification starts with
-.BR A+ ),
-then authors' last names will be used instead, provided that this does
-not introduce ambiguity,
-and also an initial subsequence of the authors may be used
-instead of all the authors, again provided that this does not
-introduce ambiguity.
-The use of only the last name for the
-.IR i -th
-author of some reference
-is considered to be ambiguous if
-there is some other reference,
-such that the first
-.IR i \|-\|1
-authors of the references are the same,
-the
-.IR i -th
-authors are not the same,
-but the
-.IR i -th
-authors' last names are the same.
-A proper initial subsequence of the sequence
-of authors for some reference is considered to be ambiguous if there is
-a reference with some other sequence of authors which also has
-that subsequence as a proper initial subsequence.
-When an initial subsequence of authors is used, the remaining
-authors are replaced by the string specified by the
-.B et-al
-command;
-this command may also specify additional requirements that must be
-met before an initial subsequence can be used.
-.B @
-tentatively evaluates to a canonical representation of the authors,
-such that authors that compare equally for sorting purpose
-will have the same representation.
-.
-.TP
-.BI % n
-.TQ
-.B %a
-.TQ
-.B %A
-.TQ
-.B %i
-.TQ
-.B %I
-The serial number of the reference formatted according to the character
-following the
-.BR % .
-The serial number of a reference is\ 1 plus the number of earlier references
-with same tentative label as this reference.
-These expressions tentatively evaluate to an empty string.
-.
-.TP
-.IB expr *
-If there is another reference with the same tentative label as
-this reference, then
-.IR expr ,
-otherwise an empty string.
-It tentatively evaluates to an empty string.
-.
-.TP
-.IB expr + n
-.TQ
-.IB expr \- n
-The first
-.RB ( + )
-or last
-.RB ( \- )
-.I n
-upper or lower case letters or digits of
-.IR expr .
-Troff special characters (such as
-.BR \e('a )
-count as a single letter.
-Accent strings are retained but do not count towards the total.
-.
-.TP
-.IB expr .l
-.I expr
-converted to lowercase.
-.
-.TP
-.IB expr .u
-.I expr
-converted to uppercase.
-.
-.TP
-.IB expr .c
-.I expr
-converted to caps and small caps.
-.
-.TP
-.IB expr .r
-.I expr
-reversed so that the last name is first.
-.
-.TP
-.IB expr .a
-.I expr
-with first names abbreviated.
-Note that fields specified in the
-.B abbreviate
-command are abbreviated before any labels are evaluated.
-Thus
-.B .a
-is useful only when you want a field to be abbreviated in a label
-but not in a reference.
-.
-.TP
-.IB expr .y
-The year part of
-.IR expr .
-.
-.TP
-.IB expr .+y
-The part of
-.I expr
-before the year, or the whole of
-.I expr
-if it does not contain a year.
-.
-.TP
-.IB expr .\-y
-The part of
-.I expr
-after the year, or an empty string if
-.I expr
-does not contain a year.
-.
-.TP
-.IB expr .n
-The last name part of
-.IR expr .
-.
-.TP
-.IB expr1 \(ti expr2
-.I expr1
-except that if the last character of
-.I expr1
-is
-.B \-
-then it will be replaced by
-.IR expr2 .
-.
-.TP
-.I expr1\ expr2
-The concatenation of
-.I expr1
-and
-.IR expr2 .
-.
-.TP
-.IB expr1 | expr2
-If
-.I expr1
-is non-empty then
-.I expr1
-otherwise
-.IR expr2 .
-.
-.TP
-.IB expr1 & expr2
-If
-.I expr1
-is non-empty
-then
-.I expr2
-otherwise an empty string.
-.
-.TP
-.IB expr1 ? expr2 : expr3
-If
-.I expr1
-is non-empty
-then
-.I expr2
-otherwise
-.IR expr3 .
-.
-.TP
-.BI < expr >
-The label is in two parts, which are separated by
-.IR expr .
-Two adjacent two-part labels which have the same first part will be
-merged by appending the second part of the second label onto the first
-label separated by the string specified in the
-.B separate-label-second-parts
-command (initially, a comma followed by a space); the resulting label
-will also be a two-part label with the same first part as before
-merging, and so additional labels can be merged into it.
-Note that it is permissible for the first part to be empty;
-this maybe desirable for expressions used in the
-.B short-label
-command.
-.
-.TP
-.BI ( expr )
-The same as
-.IR expr .
-Used for grouping.
-.
-.LP
-The above expressions are listed in order of precedence
-(highest first);
-.B &
-and
-.B |
-have the same precedence.
-.
-.
-.SS Macro interface
-Each reference starts with a call to the macro
-.BR ]- .
-The string
-.B [F
-will be defined to be the label for this reference,
-unless the
-.B no-label-in-reference
-command has been given.
-There then follows a series of string definitions,
-one for each field:
-string
-.BI [ X
-corresponds to field
-.IR X .
-The number register
-.B [P
-is set to\ 1 if the
-.B P
-field contains a range of pages.
-The
-.BR [T ,
-.B [A
-and
-.B [O
-number registers are set to\ 1 according as the
-.BR T ,
-.B A
-and
-.B O
-fields end with one of the characters
-.BR .?! .
-The
-.B [E
-number register will be set to\ 1 if the
-.B [E
-string contains more than one name.
-The reference is followed by a call to the
-.B ][
-macro.
-The first argument to this macro gives a number representing
-the type of the reference.
-If a reference contains a
-.B J
-field, it will be classified as type\ 1,
-otherwise if it contains a
-.B B
-field, it will type\ 3,
-otherwise if it contains a
-.B G
-or
-.B R
-field it will be type\ 4,
-otherwise if contains a
-.B I
-field it will be type\ 2,
-otherwise it will be type\ 0.
-The second argument is a symbolic name for the type:
-.BR other ,
-.BR journal-article ,
-.BR book ,
-.B article-in-book
-or
-.BR tech-report .
-Groups of references that have been accumulated
-or are produced by the
-.B bibliography
-command are preceded by a call to the
-.B ]<
-macro and followed by a call to the
-.B ]>
-macro.

-.TH @G@SOELIM @MAN1EXT@ "@MDATE@" "Groff Version @VERSION@"
-.
-.SH NAME
-@g@soelim \- interpret .so requests in groff input
-.
-.SH SYNOPSIS
-.B @g@soelim
-[
-.B \-Crtv
-]
-[
-.BI \-I dir
-]
-[
-.IR files \|.\|.\|.\|
-]
-.
-.PP
-It is possible to have whitespace between the
-.B \-I
-command line option and its parameter.
-.
-.SH DESCRIPTION
-.B @g@soelim
-reads
-.I files
-and replaces lines of the form
-.IP
-.BI .so\  file
-.LP
-by the contents of
-.IR file .
-It is useful if files included with
-.B so
-need to be preprocessed.
-Normally,
-.B @g@soelim
-should be invoked with the
-.B \-s
-option of
-.BR groff .
-.
-.PP
-Note that there must be no whitespace between the leading dot and
-the two characters `s' and `o'.  Otherwise, only
-.B groff
-interprets the
-.B .so
-request (and
-.B soelim
-ignores it).
-.
-.SH OPTIONS
-.TP
-.B \-C
-Recognize
-.B .so
-even when followed by a character other than space or newline.
-.
-.TP
-.BI \-I dir
-This option may be used to specify a directory to search for
-files (both those on the command line and those named in
-.B \&.so
-requests).
-The current directory is always searched first.
-This option may be specified more than once,
-the directories will be searched in the order specified.
-No directory search is performed for files specified using an absolute path.
-.
-.TP
-.B \-r
-Do not add .lf requests (for general use, with non-groff files).
-.
-.TP
-.B \-t
-Don't emit .lf requests but TeX comment lines (starting with `%') giving
-the current file and line number.
-.
-.TP
-.B \-v
-Print the version number.
-.
-.SH USAGE
-The normal processing sequence of groff is this:
-.
-.PP
-.ie t \{\
-.PS
-box invisible width 0.5 height 0.4 "input" "file";
-move to last box .bottom;
-down;
-arrow 0.3;
-box invisible width 0.8 height 0.2 "preprocessor";
-move to last box .right
-right;
-arrow 0.3;
-A: box invisible width 0.35 height 0.2 "troff";
-move to last box .top;
-up;
-move 0.3;
-box invisible width 0.6 height 0.4 "sourced" "file";
-line <- up 0.3 from A.top;
-move to A.right;
-right;
-arrow 0.3;
-box invisible width 0.85 height 0.2 "postprocessor";
-move to last box .bottom;
-down;
-arrow 0.3;
-box invisible width 0.5 height 0.4 "output" "file"
-.PE
-.\}
-.el \{\
-.nf
-          input        sourced
-          file          file
-            |             |
-            v             v
-        preprocessor -> troff -> postprocessor
-                                      |
-                                      v
-                                   output
-                                    file
-.fi
-.\}
-.PP
-.
-That is, files sourced with
-.B .so
-are normally read
-.I only
-by
-.B troff
-(the actual formatter).
-.B soelim
-is
-.I not
-required for
-.B troff
-to source files.
-.
-.PP
-If a file to be sourced should also be preprocessed, it must
-already be read
-.I before
-the input file passes through the preprocessor.
-This is handled by
-.BR soelim :
-.
-.PP
-.ie t \{\
-.PS

-move to last box .bottom;

-.TH @G@TBL @MAN1EXT@ "@MDATE@" "Groff Version @VERSION@"
-.SH NAME
-@g@tbl \- format tables for troff
-.
-.
-.SH SYNOPSIS
-.B @g@tbl
-[
-.B \-Cv
-]
-[
-.IR files \|.\|.\|.\&
-]
-.
-.
-.SH DESCRIPTION
-This manual page describes the GNU version of
-.BR tbl ,
-which is part of the groff document formatting system.
-.B tbl
-compiles descriptions of tables embedded within
-.B troff
-input files into commands that are understood by
-.BR troff .
-Normally, it should be invoked using the
-.B \-t
-option of
-.B groff.
-It is highly compatible with Unix
-.BR tbl .
-The output generated by GNU
-.B tbl
-cannot be processed with Unix
-.BR troff ;
-it must be processed with GNU
-.BR troff .
-If no files are given on the command line, the standard input
-will be read.
-A filename of
-.B \-
-will cause the standard input to be read.
-.
-.
-.SH OPTIONS
-.TP
-.B \-C
-Enable compatibility mode to
-recognize
-.B .TS
-and
-.B .TE
-even when followed by a character other than space or newline.
-Leader characters (\[rs]a) are handled as interpreted.
-.TP
-.B \-v
-Print the version number.
-.
-.
-.SH USAGE
-.B tbl
-expects to find table descriptions wrapped in the
-.B .TS
-(table start) and
-.B .TE
-(table end) macros.
-The line immediately following the
-.B .TS
-macro may contain any of the following global options (ignoring the case
-of characters -- Unix tbl only accepts options with all characters lowercase
-or all characters uppercase):
-.
-.TP
-.B center
-Centers the table (default is left-justified).
-The alternative keyword name
-.B centre
-is also recognized (this is a GNU tbl extension).
-.
-.TP
-.BI delim( xy )
-Use
-.I x
-and
-.I y
-as start and end delimiters for
-.BR @g@eqn (@MAN1EXT@).
-.
-.TP
-.B expand
-Makes the table as wide as the current line length.
-.
-.TP
-.B box
-Encloses the table in a box.
-.
-.TP
-.B doublebox
-Encloses the table in a double box.
-.
-.TP
-.B allbox
-Encloses each item of the table in a box.
-.
-.TP
-.B frame
-Same as box (GNU tbl only).
-.
-.TP
-.B doubleframe
-Same as doublebox (GNU tbl only).
-.
-.TP
-.BI tab( x )
-Uses the character
-.I x
-instead of a tab to separate items in a line of input data.
-.
-.TP
-.BI linesize( n )
-Sets lines or rules (e.g. from
-.BR box )
-in
-.IR n -point
-type.
-.
-.TP
-.B nokeep
-Don't use diversions to prevent page breaks (GNU tbl only).
-Normally
-.B tbl
-attempts to prevent undesirable breaks in the table by using diversions.
-This can sometimes interact badly with macro packages' own use of
-diversions, when footnotes, for example, are used.
-.
-.TP
-.BI decimalpoint( c )
-Set the character to be recognized as the decimal point in numeric
-columns (GNU tbl only).
-.
-.TP
-.B nospaces
-Ignore leading and trailing spaces in data items (GNU tbl only).
-.
-.LP
-The global options must end with a semicolon.
-There might be whitespace after an option and its argument in parentheses.
-.LP
-After global options come lines describing the format of each line of
-the table.
-Each such format line describes one line of the table itself, except that
-the last format line (which you must end with a period) describes all
-remaining lines of the table.
-A single key character describes each column of each line of the table.
-You may run format specs for multiple lines together on the same line by
-separating them with commas.
-.LP
-You may follow each key character with specifiers that determine the font
-and point size of the corresponding item, that determine column width,
-inter-column spacing, etc.
-.LP
-The longest format line defines the number of columns in the table; missing
-format descriptors at the end of format lines are assumed to be `L'.
-Extra columns in the data (which have no corresponding format entry) are
-ignored.
-.LP
-The available key characters are:
-.
-.TP
-c,C
-Centers item within the column.
-.
-.TP
-r,R
-Right-justifies item within the column.
-.
-.TP
-l,L
-Left-justifies item within the column.
-.
-.TP
-n,N
-Numerically justifies item in the column: Units positions of numbers are
-aligned vertically.
-.
-.TP
-s,S
-Spans previous item on the left into this column.
-.
-.TP
-a,A
-Centers longest line in this column and then left-justifies all other lines
-in this column with respect to that centered line.
-.
-.TP
-^
-Spans down entry from previous row in this column.
-.
-.TP
-_,-
-Replaces this entry with a horizontal line.
-.
-.TP
-=
-.
-Replaces this entry with a double horizontal line.
-.
-.TP
-|
-The corresponding column becomes a vertical rule (if two of these are
-adjacent, a double vertical rule).
-.
-.LP
-A vertical bar to the left of the first key-letter or to the right of the
-last one produces a line at the edge of the table.
-.LP
-Here are the specifiers that can appear in suffixes to column key letters:
-.
-.TP
-b,B
-Short form of fB (make affected entries bold).
-.
-.TP
-i,I
-Short form of fI (make affected entries italic).
-.
-.TP
-t,T
-Start an item vertically spanning rows at the top of its range rather than
-vertically centering it.
-.
-.TP
-d,D
-Start an item vertically spanning rows at the bottom of its range rather
-than vertically centering it (GNU tbl only).
-.
-.TP
-v,V
-Followed by a number, this indicates the vertical line spacing to be used in
-a multi-line table entry.
-If signed, the current vertical line spacing is incremented or decremented
-(using a signed number instead of a signed digit is a GNU tbl extension).
-A vertical line spacing specifier followed by a column separation number
-must be separated by one or more blanks.
-No effect if the corresponding table entry isn't a text block.
-.
-.TP
-f,F
-Either of these specifiers may be followed by a font name (either one or two
-characters long), font number (a single digit), or long name in parentheses
-(the last form is a GNU tbl extension).
-A one-letter font name must be separated by one or more blanks from whatever
-follows.
-.
-.TP
-p,P
-Followed by a number, this does a point size change for the affected fields.
-If signed, the current point size is incremented or decremented (using a
-signed number instead of a signed digit is a GNU tbl extension).
-A point size specifier followed by a column separation number must be
-separated by one or more blanks.
-.
-.TP
-w,W
-Minimal column width value.
-Must be followed either by a
-.BR @g@troff (@MAN1EXT@)
-width expression in parentheses or a unitless integer.
-If no unit is given, en units are used.
-Also used as the default line length for included text blocks.
-If used multiple times to specify the width for a particular column,
-the last entry takes effect.
-.
-.TP
-x,X
-This is a GNU tbl extension.
-Either of these specifiers may be followed by a macro name 
-(either one or two characters long),
-or long name in parentheses.
-A one-letter macro name must be separated by one or more blanks
-from whatever follows.
-The macro which name can be specified here
-must be defined before creating the table.
-It is called just before the table's cell text is output. 
-As implemented currently, this macro is only called if block input is used,
-that is, text between `T{' and `T}'.
-The macro should contain only simple
-.B troff
-requests to change the text block formatting, like text adjustment,
-hyphenation, size, or font.
-The macro is called
-.I after
-other cell modifications like
-.BR b ,
-.B f
-or
-.B v
-are output.
-Thus the macro can overwrite other modification specifiers.
-.
-.TP
-e,E
-Make equally-spaced columns.
-.
-.TP
-u,U
-Move the corresponding column up one half-line.
-.
-.TP
-z,Z
-Ignore the corresponding column for width-calculation purposes.
-.
-.LP
-A number suffix on a key character is interpreted as a column
-separation in ens (multiplied in proportion if the
-.B expand
-option is on).
-Default separation is 3n.
-.LP
-The format lines are followed by lines containing the actual data for the
-table, followed finally by
-.BR .TE .
-Within such data lines, items are normally separated by tab characters (or
-the character specified with the
-.B tab
-option).
-Long input lines can be broken across multiple lines if the last character
-on the line is `\e' (which vanishes after concatenation).
-.LP
-A dot starting a line, followed by anything but a digit is handled as a
-troff command, passed through without changes.
-The table position is unchanged in this case.
-.LP
-If a data line consists of only `_' or `=', a single or double line,
-respectively, is drawn across the table at that point; if a single item in a
-data line consists of only `_' or `=', then that item is replaced by a
-single or double line, joining its neighbours.
-If a data item consists only of `\e_' or `\e=', a single or double line,
-respectively, is drawn across the field at that point which does not join
-its neighbours.
-.LP
-A data item consisting only of `\eRx' (`x' any character) is replaced by
-repetitions of character `x' as wide as the column (not joining its
-neighbours).
-.LP
-A data item consisting only of `\e^' indicates that the field immediately
-above spans downward over this row.
-.LP
-A text block can be used to enter data as a single entry which would be
-too long as a simple string between tabs.
-It is started with `T{' and closed with `T}'.
-The former must end a line, and the latter must start a line, probably
-followed by other data columns (separated with tabs).
-By default, the text block is formatted with the settings which were
-active before entering the table, possibly overridden by the
-.B v
-and
-.B w
-tbl specifiers.
-For example, to make all text blocks ragged-right, insert
-.B .na
-right before the starting
-.B .TS
-(and
-.B .ad
-after the table).
-.LP
-To change the data format within a table, use the
-.B .T&
-command (at the start of a line).
-It is followed by format and data lines (but no global options) similar to
-the
-.B .TS
-request.
-.
-.
-.SH "INTERACTION WITH @G@EQN"
-.BR @g@tbl (@MAN1EXT@)
-should always be called before
-.BR @g@eqn (@MAN1EXT@)
-.RB ( groff (@MAN1EXT@)
-automatically takes care of the correct order of preprocessors).
-.
-.
-.SH "GNU TBL ENHANCEMENTS"
-There is no limit on the number of columns in a table, nor any limit on the
-number of text blocks.
-All the lines of a table are considered in deciding column widths, not just
-the first 200.
-Table continuation
-.RB ( .T& )
-lines are not restricted to the first 200 lines.
-.LP
-Numeric and alphabetic items may appear in the same column.
-.LP
-Numeric and alphabetic items may span horizontally.
-.LP
-.B @g@tbl
-uses register, string, macro and diversion names beginning with the digit\~\c
-.BR 3 .
-When using
-.B @g@tbl
-you should avoid using any names beginning with a\~\c
-.BR 3 .
-.
-.
-.SH BUGS
-You should use
-.BR .TS\ H / .TH
-in conjunction with a supporting macro package for
-.I all
-multi-page boxed tables.
-If there is no header that you wish to appear at the top of each page
-of the table, place the
-.B .TH
-line immediately after the format section.
-Do not enclose a multi-page table within keep/release macros,
-or divert it in any other way.
-.LP
-A text block within a table must be able to fit on one page.
-.LP
-The
-.B bp
-request cannot be used to force a page-break in a multi-page table.
-Instead, define
-.B BP
-as follows
-.IP
-.B .de BP
-.br
-.B .ie '\e\en(.z'' .bp \e\e$1
-.br
-.B .el \e!.BP \e\e$1
-.br
-.B ..
-.br
-.LP
-and use
-.B BP
-instead of
-.BR bp .
-.LP
-Using \ea directly in a table to get leaders will not work (except in
-compatibility mode).
-This is correct behaviour: \ea is an
-.B uninterpreted
-leader.
-To get leaders use a real leader, either by using a control A or like
-this:
-.IP
-.nf
-.ft B
-\&.ds a \ea
-\&.TS
-tab(;);
-lw(1i) l.
-A\e*a;B
-\&.TE
-.ft

-.P
-The command line is parsed according to the usual GNU convention.
-.
-The whitespace between a command line option and its argument is
-optional.
-.
-Options can be grouped behind a single
-.ShortOpt
-(minus character).
-.
-A filename of
-.ShortOpt
-(minus character) denotes the standard input.

-.\" --------------------------------------------------------------------
-.SH DESCRIPTION
-.\" --------------------------------------------------------------------
-.
-This document describes the
-.B groff
-program, the main front-end for the 
-.I groff
-document formatting system.
-.
-The
-.I groff
-program and macro suite is the implementation of a
-.BR roff (@MAN7EXT@)
-system within the free software collection
-.URL http://\:www.gnu.org "GNU" .
-.
-The
-.I groff
-system has all features of the classical
-.IR roff ,
-but adds many extensions.
-.
-.P
-The
-.B groff
-program allows to control the whole
-.I groff
-system by command line options.
-.
-This is a great simplification in comparison to the classical case (which
-uses pipes only).
-.
-.
-.\" --------------------------------------------------------------------
-.SH OPTIONS
-.\" --------------------------------------------------------------------
-.
-As
-.B groff
-is a wrapper program for
-.B @g@troff
-both programs share a set of options.
-.
-But the
-.B groff
-program has some additional, native options and gives a new meaning to
-some
-.B @g@troff
-options.
-.
-On the other hand, not all
-.B @g@troff
-options can be fed into
-.BR groff .
-.
-.
-.\" --------------------------------------------------------------------
-.SS Native groff Options
-.\" --------------------------------------------------------------------
-.
-The following options either do not exist for
-.B @g@troff
-or are differently interpreted by
-.BR groff .
-.
-.
-.OptDef e
-Preprocess with
-.BR @g@eqn .
-.
-.
-.OptDef g
-Preprocess with
-.BR @g@grn .
-.
-.
-.OptDef G
-Preprocess with

-.
-.TP
-.EnvVar GROFF_COMMAND_PREFIX
-When there is a need to run different roff implementations at the same
-time
-.I groff
-provides the facility to prepend a prefix to most of its programs that
-could provoke name clashings at run time (default is to have none).
-.
-Historically, this prefix was the character
-.BR g ,
-but it can be anything.
-.
-For example,
-.BR gtroff
-stood for
-.IR groff 's
-.BR troff ,
-.BR gtbl
-for the

-.SH EXAMPLES
-.\" --------------------------------------------------------------------
-.
-The following example illustrates the power of the
-.B groff
-program as a wrapper around
-.BR @g@troff .
-.
-.P
-To process a roff file using the preprocessors
-.B tbl
-and
-.B pic
-and the
-.B me
-macro set, classical troff had to be called by
-.
-.P
-.ShellCommand pic foo.me | tbl | troff \*[@-]me \*[@-]Tlatin1 | grotty
-.
-.P
-Using
-.BR groff ,
-this pipe can be shortened to the equivalent command
-.P
-.ShellCommand groff \*[@-]p \*[@-]t \*[@-]me \*[@-]T latin1 foo.me
-.
-.P
-An even easier way to call this is to use
-.BR grog (@MAN1EXT@)
-to guess the preprocessor and macro options and execute the generated
-command (by using backquotes to specify shell command substitution)
-.P
-.ShellCommand \`grog \*[@-]Tlatin1 foo.me\`
-.
-.P
-The simplest way is to view the contents in an automated way by
-calling
-.
-.P
-.ShellCommand groffer foo.me
-.

-.SH BUGS
-.\" --------------------------------------------------------------------
-.
-.P
-On EBCDIC hosts (e.g. OS/390 Unix), output devices
-.B ascii
-and
-.B latin1
-aren't available.
-.
-Similarly, output for EBCDIC code page
-.B cp1047
-is not available on ASCII based operating systems.
-.

-Report bugs to bug-groff@gnu.org.
-.
-Include a complete, self-contained example that will allow the bug to
-be reproduced, and say which version of groff you are using.

-grog \- guess options for groff command
-.SH SYNOPSIS
-.B grog
-[
-.BI \- option
-\|.\|.\|.\&
-]
-[
-.IR files\  \|.\|.\|.\&
-]
-.SH DESCRIPTION
-.B grog
-reads
-.I files
-and guesses which of the
-.BR groff  (@MAN1EXT@)
-options
-.BR \-e ,
-.BR \-man ,
-.BR \-me ,
-.BR \-mm ,
-.BR \-mom ,
-.BR \-ms ,
-.BR \-mdoc,
-.BR \-mdoc-old,
-.BR \-p ,
-.BR \-R ,
-.BR \-g ,
-.BR \-G ,
-.BR \-s ,
-and
-.BR \-t
-are required for printing
-.IR files ,
-and prints the groff command including those options on the standard output.
-A filename of
-.B \-
-is taken to refer to the standard input.
-If no files are specified the standard input will be read.
-Any specified options will be included in the printed command.
-No space is allowed between options and their arguments.
-The only options recognized are
-.B \-C
-(which is also passed on) to enable compatibility mode, and
-.B \-v
-to print the version number.
-.LP
-For example,
-.IP
-.B \`grog \-Tdvi paper.ms\`
-.LP
-will guess the appropriate command to print
-.B paper.ms
-and then run it after adding the
-.B \-Tdvi
-option.

-.SH DESCRIPTION
-The
-.B @g@nroff
-script emulates the
-.B nroff
-command using groff.
-Only 
-.BR ascii ,
-.BR latin1 ,
-.BR koi8-r ,
-.BR utf8 ,
-and
-.B cp1047
-are valid arguments for the
-.B -T
-option, selecting the output encoding emitted by
-.BR grotty ,
-groff's TTY output device.
-If an invalid or no
-.BR \-T
-option is given,
-.B @g@nroff
-checks the current locale to select a default output device.
-It first tries the
-.B locale
-program, then the environment variables
-.BR LC_ALL ,
-.BR LC_CTYPE ,
-and
-.BR LANG ,
-and finally the
-.B LESSCHARSET
-environment variable.
-.PP
-The
-.B \-h
-and
-.B \-c
-options
-are equivalent to
-.BR grotty 's
-options
-.B \-h
-(using tabs in the output) and
-.B \-c
-(using the old output scheme instead of SGR escape sequences).
-The
-.BR \-d ,
-.BR \-C ,
-.BR \-i ,
-.BR \-M ,
-.BR \-m ,
-.BR \-n ,
-.BR \-o ,
-and
-.B \-r
-options have the effect described in
-.BR @g@troff (@MAN1EXT@).
-In addition,
-.B @g@nroff
-silently ignores the options
-.BR \-e ,
-.BR \-q ,
-and
-.BR \-s
-(which are not implemented in
-.BR @g@troff ).
-Options 
-.B \-p
-(pic),
-.B \-t
-(tbl),
-.B \-S
-(safer), and
-.B \-U
-(unsafe) are passed to
-.BR groff . 
-.B \-v
-shows the version number.
-.
-.SH ENVIRONMENT
-.TP
-.SM
-.B GROFF_BIN_PATH
-A colon separated list of directories in which to search for the
-.B groff
-executable before searching in PATH.  If unset, `@BINDIR@' is used.
-.SH NOTES
-This shell script is basically intended for use with
-.BR man (1),
-so warnings are suppressed.
-nroff-style character definitions (in the file tty-char.tmac) are also
-loaded to emulate unrepresentable glyphs.
-.
-.SH "SEE ALSO"
-.BR groff (@MAN1EXT@),
-.BR @g@troff (@MAN1EXT@),
-.BR grotty (@MAN1EXT@)

-A line prefix request to make e.g. French quotation possible:
-
-  He said: >> blablablabla
-  >> blablabla blabla  bla
-  >> blabla blabla bla bla
-  >> bla bla bla blablabla
-  >> blabla. <<
-
-Give a more helpful error message when the indent is set to a value
-greater than the line-length.
-
-Tracing. This is a pain to implement because requests are responsible
-for reading their own arguments.
-
-Possibly implement -s option (stop every N pages). This functionality
-would be more appropriate in a postprocessor.
-
-Line breaking should be smarter.  In particular, it should be possible
-to shrink spaces.  Also avoid having a line that's been shrunk a lot
-next to a line that's been stretched a lot.  The difficulty is to
-design a mechanism that allows the user complete control over the
-decision of where to break the line.
-
-Provide a mechanism to control the shape of the rag in non-justified
-text.
-
-Add a discretionary break escape sequence. \='...'...'...' like TeX.
-
-Think about kerning between characters and spaces. (Need to implement
-get_breakpoints and split methods for kern_pair_node class.)
-
-In troff, if .L > 1 when a diversion is reread in no-fill mode, then
-extra line-spacing is added on. Groff at the moment treats line-spacing
-like vertical spacing and doesn't do this. 
-
-Suppose \(ch comes from a special font S, and that the current font is
-R. Suppose that R contains a hyphen character and that S does not.
-Suppose that the current font is R. Suppose that \(ch is in a word
-and has a non-zero hyphen-type. Then we ought to be able to hyphenate,
-but we won't be able to because we will look for the hyphen only in
-font S and not in font R.
-
-Perhaps the current input level should be accessible in a number register.
-
-Should \w deal with a newline like \X?
-
-Have another look at uses of token::delimiter.  Perhaps we need to
-distinguish the case where we want to see if a token could start a
-number, from the case where we want to see if it could occur somewhere
-in a number expression.
-
-Provide a facility like copy thru in pic.
-
-Fancier implementation of font families which doesn't group fonts into
-families purely on the basis of their names.
-
-In the DESC file make the number of fonts optional if they are all on
-one line.
-
-Number register to give the diversion level.
-
-Time various alternative implementations of scale (both in font.c and
-number.c). On a sparc it's faster to always do it in floating point.
-
-Devise a more compact representation for the hyphenation patterns trie.
-
-Have a per-environment parameter to increase letter-spacing.
-
-Number register to return character height.
-
-Number register to return character slant.
-
-Request to set character height.
-
-Request to set character slant.
-
-Provide some way to upcase or downcase strings.
-
-Support non-uniformly scalable fonts. Perhaps associate a suffix with
-a particular range of sizes.  eg
-  sizesuffix .display 14-512
-Then is you ask for R at pointsize 16, groff will first look for
-R.display and then R.  Probably necessary to be able to specify a
-separate unitwidth for each sizesuffix (eg. for X).
-
-Make it possible to suppress hyphenation on a word-by-word basis.
-(Perhaps store hyphenation flags in tfont.)
-
-Possibly allow multiple simultaneous input line traps.
-
-Unpaddable, breakable space escape sequence.
-
-Support hanging punctuation.
-
-In justified text, if the last line of a paragraph is only a little
-bit short it might be desirable to justify the line.  Allow the user
-control over this.
-
-The pm request could print where the macro was defined.  Also could
-optionally print the contents of a macro.
-
-Provide some way to round numbers to multiples of the current
-horizontal or vertical resolution.
-
-Better string-processing support (search).
-
-Generalized ligatures.
-
-Provide some way for a macro to tell whether it was called with `'' or
-`.'.  This would be useful for implementing a tracing macro package.
-
-Request to remove an environment. (Maintain a count of the references
-to the environment from the environment table, environment dictionary
-or environment stack.)
-
-Perhaps in the nr request a leading `-' should only be recognized as a
-decrement when it's at the same input level as the request.
-
-Don't ever change a charinfo.  Create new variants instead and chain
-them together.
-
-Unix troff appears to read the first character of a request name in
-copy mode.  Should we do the same?
-
-Number register giving name of end macro.
-
-More thorough range checking.
-
-Provide syntax for octal and hexadecimal numeric constants.  Perhaps
-o#100 and x#7f as per Scheme.  Or perhaps PostScript 16#7f.  Ambiguity
-between whether `c' is treated as digit or scaling indicator.

-Do the break at the end of input after the end macro (if any).

-Unix troff behaves as follows:  if the last line is

-foo bar\c
-
-it will output foo on the current page, and bar on the next page;
-if the last line is
-
-foo\c
-
-or
-
-foo bar
-
-everything will be output on the current page.  This behaviour must be

-
-The problem is that some macro packages rely on this.  For example,
-the ATK macros have an end macro that emits \c if it needs to print a
-table of contents but doesn't do a 'bp in the end macro; instead the
-'bp is done in the bottom of page trap.  This works with Unix troff,
-provided that the current environment is not empty at the end of the
-input file.
-
-The following will make macro packages that do that sort of thing work
-even if the current environment is empty at the end of the input file.
-If the last input line used \c and this line occurred in the end macro,
-then we'll force everything out on the current page, but we'll make
-sure that the environment isn't empty so that we won't exit at the

-.SH DESCRIPTION
-.\" --------------------------------------------------------------------
-.
-This manual page describes the GNU version of
-.BR troff .
-It is part of the groff document formatting system.
-.
-It is functionally compatible with UNIX troff, but has many extensions,
-see
-.BR \%groff_diff (@MAN7EXT@).
-Usually it should be invoked using the
-.BR groff (@MAN1EXT@)
-command which will also run preprocessors and postprocessors in the
-appropriate order and with the appropriate options.
-.
-.
-.\" --------------------------------------------------------------------
-.SH OPTIONS
-.\" --------------------------------------------------------------------
-.
-.TP \w'\-dname=s'u+2n
-.B \-a
-Generate an
-.SM ASCII
-approximation of the typeset output.
-.
-.TP
-.B \-b
-Print a backtrace with each warning or error message.
-.
-This backtrace should help track down the cause of the error.
-.
-The line numbers given in the backtrace may not always be correct, for
-.BR @g@troff 's
-idea of line numbers gets confused by
-.B as
-or 
-.B am
-requests.
-.
-.TP
-.B \-c
-Disable color output (always disabled in compatibility mode).
-.
-.TP
-.B \-C
-Enable compatibility mode.
-.
-.TP
-.BI \-d cs
-.TQ
-.BI \-d name = s
-Define
-.I c
-or
-.I name
-to be a string
-.IR s ;
-.I c
-must be a one letter name.
-.
-.TP
-.B \-E
-Inhibit all error messages of
-.BR @g@troff .
-Note that this doesn't affect messages output to standard error by macro
-packages using the
-.B tm
-or
-.B tm1
-requests.
-.
-.TP
-.BI \-f fam
-Use
-.I fam
-as the default font family.
-.
-.TP
-.BI \-F dir
-Search in directory (or directory path)
-.I dir
-for subdirectories
-.BI dev name

-.I dir
-is scanned before all other font directories.
-.
-.TP
-.B \-i
-Read the standard input after all the named input files have been
-processed.
-.
-.TP
-.BI \-I dir
-This option may be used to specify a directory to search for
-files (both those on the command line and those named in
-.B \&.psbb
-requests).
-The current directory is always searched first.
-This option may be specified more than once;
-the directories will be searched in the order specified.
-No directory search is performed for files specified using an absolute path.
-.
-.TP
-.BI \-m name
-Read in the file
-.IB name .tmac\fR.
-If it isn't found, try
-.BI tmac. name
-instead.
-.
-It will be first searched for in directories given with the
-.B \-M
-command line option, then in directories given in the
-.B GROFF_TMAC_PATH
-environment variable, then in the current directory (only if in unsafe
-mode), the home directory, @SYSTEMMACRODIR@, @LOCALMACRODIR@, and
-@MACRODIR@.
-.
-.TP
-.BI \-M dir
-Search directory (or directory path)
-.I dir
-for macro files.
-.
-This is scanned before all other macro directories.
-.
-.TP
-.BI \-n num
-Number the first page
-.IR num .
-.
-.TP
-.BI \-o list
-Output only pages in
-.IR list ,
-which is a comma-separated list of page ranges;
-.I n
-means print page
-.IR n ,

-The warnings that can be given by
-.B @g@troff
-are divided into the following categories.
-.
-The name associated with each warning is used by the
-.B \-w
-and
-.B \-W
-options; the number is used by the
-.B warn
-request, and by the
-.B .warn
-register; it is always a power of 2 to allow bitwise composition.

-.P
-.nr x \w'\fBright-brace'+1n+\w'00000'u
-.ta \nxuR
-.
-.TP \nxu+3n
-.BR break "\t4"
-In fill mode, lines which could not be broken so that their length was
-less than the line length.
-.
-This is enabled by default.
-.
-.TP
-.BR char "\t1"
-Non-existent characters.
-.
-This is enabled by default.
-.
-.TP
-.BR color "\t524288"
-Color related warnings.
-.
-.TP
-.BR delim "\t8"
-Missing or mismatched closing delimiters.
-.
-.TP
-.BR di "\t256"
-Use of
-.B di
-or
-.B da
-without an argument when there is no current diversion.
-.
-.TP
-.BR el "\t16"
-Use of the
-.B el
-request with no matching
-.B ie
-request.
-.
-.TP
-.BR escape "\t32768"
-Unrecognized escape sequences.
-.
-When an unrecognized escape sequence is encountered, the escape
-character is ignored.
-.
-.TP
-.BR font "\t131072"
-Non-existent fonts.
-.
-This is enabled by default.
-.
-.TP
-.BR ig "\t262144"
-Invalid escapes in text ignored with the
-.B ig
-request.
-.
-These are conditions that are errors when they do not occur in ignored
-text.
-.
-.TP
-.BR input "\t16384"
-Invalid input characters.
-.
-.TP
-.BR mac "\t512"
-Use of undefined strings, macros and diversions.
-.
-When an undefined string, macro or diversion is used, that string is
-automatically defined as empty.
-.
-So, in most cases, at most one warning will be given for each name.
-.
-.TP
-.BR missing "\t8192"
-Requests that are missing non-optional arguments.
-.
-.TP
-.BR number "\t2"
-Invalid numeric expressions.
-.
-This is enabled by default.
-.
-.TP
-.BR range "\t64"
-Out of range arguments.
-.
-.TP
-.BR reg "\t1024"
-Use of undefined number registers.
-.
-When an undefined number register is used, that register is
-automatically defined to have a value of\~0.
-.
-So, in most cases, at most one warning will be given for use of a
-particular name.
-.
-.TP
-.BR right-brace "\t4096"
-Use of
-.B \[rs]}
-where a number was expected.
-.
-.TP
-.BR scale "\t32"
-Meaningless scaling indicators.
-.
-.TP
-.BR space "\t65536"
-Missing space between a request or macro and its argument.
-.
-This warning will be given when an undefined name longer than two
-characters is encountered, and the first two characters of the name
-make a defined name.
-.
-The request or macro will not be invoked.
-.
-When this warning is given, no macro is automatically defined.
-.
-This is enabled by default.
-.
-This warning will never occur in compatibility mode.
-.
-.TP
-.BR syntax "\t128"
-Dubious syntax in numeric expressions.
-.
-.TP
-.BR tab "\t2048"
-Inappropriate use of a tab character.
-Either use of a tab character where a number was expected, or use of tab
-character in an unquoted macro argument.
-.
-.P
-There are also names that can be used to refer to groups of warnings:
-.
-.TP
-.B all
-All warnings except
-.BR di ,
-.BR mac ,
-and
-.BR reg .
-It is intended that this covers all warnings that are useful with
-traditional macro packages.
-.
-.TP
-.B w
-All warnings.

-.TH ADDFTINFO @MAN1EXT@ "@MDATE@" "Groff Version @VERSION@"
-.SH NAME
-addftinfo \- add information to troff font files for use with groff
-.SH SYNOPSIS
-.B addftinfo
-[
-.B \-v
-]
-[
-.BI \- param\ value\fR.\|.\|.
-]
-.I res
-.I unitwidth
-.I font
-.SH DESCRIPTION
-.B addftinfo
-reads a troff font file
-and adds some additional font-metric information
-that is used by the groff system.
-The font file with the information added is written on the
-standard output.
-The information added is guessed using 
-some parametric information about the font
-and assumptions
-about the traditional troff names for characters.
-The main information added is the heights and depths of characters.
-The
-.I res
-and
-.I unitwidth
-arguments should be the same as the corresponding parameters
-in the DESC file;
-.I font
-is the name of the file describing the font;
-if
-.I font
-ends with
-.B I
-the font will be assumed to be italic.
-.SH OPTIONS
-.B \-v
-prints the version number.
-.LP
-All other options changes one of the parameters that is used
-to derive the heights and depths.
-Like the existing quantities in the font
-file, each
-.I value
-is in
-.RI inches/ res
-for a font whose point size is
-.IR unitwidth .
-.I param
-must be one of:
-.TP
-.B x-height
-The height of lowercase letters without ascenders such as x.
-.TP
-.B fig-height
-The height of figures (digits).
-.TP
-.B asc-height
-The height of characters with ascenders, such as b, d or l.
-.TP
-.B body-height
-The height of characters such as parentheses.
-.TP
-.B cap-height
-The height of uppercase letters such as A.
-.TP
-.B comma-depth
-The depth of a comma.
-.TP
-.B desc-depth
-The depth of characters with descenders, such as p,q, or y.
-.TP
-.B body-depth
-The depth of characters such as parentheses.
-.LP
-.B addftinfo
-makes no attempt to use the specified parameters to guess
-the unspecified parameters.
-If a parameter is not specified the default will be used.
-The defaults are chosen to have the reasonable values for
-a Times font.

-.
-.SH DESCRIPTION
-.B afmtodit
-creates a font file for use with groff and
-.BR grops .
-.
-.B afmtodit
-is written in perl;
-you must have perl version 5.004 or newer installed in order to run
-.BR afmtodit .
-.
-.LP
-.I afm_file
-is the AFM (Adobe Font Metric) file for the font.
-.
-.LP
-.I map_file
-is a file that says which groff character names map onto
-each PostScript character name;
-this file should contain a sequence of lines of the form
-.IP
-.I
-ps_char groff_char
-.LP
-where
-.I ps_char
-is the PostScript name of the character
-and
-.I groff_char
-is the groff name of the character (as used in the groff font file).
-.
-The same
-.I ps_char
-can occur multiple times in the file;
-each
-.I groff_char
-must occur at most once.
-.
-Lines starting with
-.B #
-and blank lines are ignored.
-.
-If the file isn't found in the current directory, it is searched in
-the `devps/generate' subdirectory of the default font directory.
-.
-.LP
-If a PostScript character is not named as
-.BI uni XXXX
-.RI ( XXXX
-are four uppercase hexadecimal digits), and is not mentioned in
-.IR map_file ,
-and a generic groff glyph name can't be deduced using the
-Adobe Glyph List (AGL, built into
-.BR  afmtodit ),
-then
-.B afmtodit
-puts the PostScript character into the groff font file as an unnamed
-character which can only be accessed by the
-.B \eN
-escape sequence in
-.BR troff .
-.
-If option
-.B \-e
-is not specified, the encoding defined in the AFM file (i.e., entries
-with non-negative character codes) is used.
-.
-Please refer to section `Using Symbols' in the groff info file which
-describes how groff glyph names are constructed.
-.
-.LP
-Characters not encoded in the AFM file (i.e., entries which have \-1 as
-the character code) are still available in groff; they get glyph index
-values greater than 255 (or greater than the biggest character code used
-in the AFM file in the unlikely case that it is greater than 255) in the
-groff font file.
-.
-Glyph indices of unencoded characters don't have a specific order; it
-is best to access them with glyph names only.
-.
-.LP
-The groff font file will be output to a file called
-.IR font .
-.
-.LP
-If there is a downloadable font file for the font, it may be listed in
-the file
-.BR @FONTDIR@/devps/download ;
-see
-.BR grops (@MAN1EXT@).
-.
-.LP
-If the
-.B \-i
-option is used,
-.B afmtodit
-will automatically generate an italic correction,
-a left italic correction and a subscript correction
-for each character
-(the significance of these parameters is explained in
-.BR groff_font (@MAN5EXT@));
-these parameters may be specified for individual characters by
-adding to the
-.I afm_file
-lines of the form:
-.IP
-.BI italicCorrection\  ps_char\ n
-.br
-.BI leftItalicCorrection\  ps_char\ n
-.br
-.BI subscriptCorrection\  ps_char\ n
-.LP
-where
-.I ps_char
-is the PostScript name of the character,
-and
-.I n
-is the desired value of the corresponding parameter in thousandths of an em.
-.
-These parameters are normally needed only for italic (or oblique) fonts.
-.
-.
-.SH OPTIONS
-.TP
-.BI \-a n
-Use
-.I n
-as the slant parameter in the font file;
-this is used by groff in the positioning of accents.
-.
-By default
-.B afmtodit
-uses the negative of the ItalicAngle specified in the afm file;
-with true italic fonts it is sometimes desirable to use
-a slant that is less than this.
-.
-If you find that characters from an italic font have accents
-placed too far to the right over them,
-then use the
-.B \-a
-option to give the font a smaller slant.
-.
-.TP
-.BI \-d desc_file
-The device description file is
-.I desc_file
-rather than the default
-.BR DESC .

-.SH DESCRIPTION
-.\" --------------------------------------------------------------------------
-.B hpftodit
-creates a font file for use with a Hewlett-Packard LaserJet~4\(enseries
-(or newer) printer with
-.BR "groff \-Tlj4" ,
-using data from an HP tagged font metric (TFM) file.
-.I tfm_file
-is the name of the TFM file for the font; Intellifont and
-TrueType TFM files are supported, but symbol set TFM files are not.
-.I map_file
-is a file giving the groff names for characters in the font; this file
-should consist of a sequence of lines of the form:
-.IP
-.I
-m u c1 c2 \fR.\|.\|. [ 
-.CW #
-.I comment
-]
-.LP
-where
-.I m
-is a decimal integer giving the MSL number of the character,
-.I u
-is a hexadecimal integer giving the Unicode value of the character,
-and
-.IR c1 ,
-.IR c2 ", .\|.\|."
-are the groff names of the character.
-The values can be separated by any whitespace; the Unicode value must
-use uppercase digits A\^\(en\^F, and must be without a leading
-.CW ` 0x ',
-.CW ` u ',
-or
-.CW ` U+ '.
-Unicode values corresponding to composite glyphs are decomposed; e.g.,
-.CW ` u00C0 '
-becomes
-.CW ` u0041_0300 '.
-The name for a glyph without a groff name may be given as
-.CW u \fIXXXX\fP
-if the glyph corresponds to a Unicode value, or as an unnamed glyph
-.CW ` --- '.
-If the given Unicode value is in the Private Use Area
-(0xE000\^\(en\^0xF8FF), the glyph is included as an unnamed glyph.
-Refer to
-.BR groff_diff (@MAN1EXT@)
-for additional information about unnamed glyphs and how to access them.
-.LP
-Blank lines and lines beginning with
-.CW ` # '
-are ignored.
-A
-.CW ` # '
-following one or more groff names begins a comment.
-Because
-.CW ` # '
-is a valid groff name, it must appear first in a list of
-groff names if a comment is included, e.g.,
-.IP
-.CW "3   0023   #   # number sign"
-.LP
-or
-.IP
-.CW "3   0023   # sh   # number sign"
-.LP
-rather than
-.IP
-.CW "3   0023   sh #   # number sign"
-.LP
-which will treat the first
-.CW ` # '
-as the beginning of the comment.
-.LP
-.I font
-is the name of the groff font file.
-The groff font file is written to
-.IR font ;
-if
-.I font
-is specified as
-.CW ` - ',
-the output is written to the standard output.
-.LP
-The
-.B \-s
-option should be given if the font is special
-(a font is
-.I special
-if
-.B troff
-should search it whenever
-a character is not found in the current font).
-If the font is special,
-it should be listed in the
-.B fonts
-command in the DESC file;
-if it is not special, there is no need to list it, since
-.B troff
-can automatically mount it when it's first used.
-.LP
-If the
-.B \-i
-option is used,
-.B hpftodit
-automatically will generate an italic correction,
-a left italic correction and a subscript correction
-for each character
-(the significance of these parameters is explained in
-.BR groff_font (@MAN5EXT@)).
-.\" --------------------------------------------------------------------------
-.SH OPTIONS
-.\" --------------------------------------------------------------------------
-.TP
-.B \-a
-Include characters in the TFM file that are not included in the map
-file.
-A glyph with corresponding Unicode value is given the name
-.RI u XXXX ;
-a glyph without a Unicode value is included as an unnamed glyph
-\&`\-\^\-\^\-'.
-A glyph with a Unicode value in the Private Use Area
-(0xE000\^\(en\^0xF8FF) also is included as an unnamed glyph.
-.IP
-This option provides a simple means of adding Unicode-named and unnamed
-glyphs to a font without including them in the map file, but it affords
-little control over which glyphs are placed in a regular font and which
-are placed in a special font.
-The presence or absence of the
-.B \-s
-option has some effect on which glyphs are included: without the
-.B \-s
-option, only the \(lqtext\(rq symbol sets are searched for matching
-glyphs; with the
-.B \-s
-option, only the \(lqmathematical\(rq symbol sets
-are searched.
-Nonetheless, restricting the symbol sets searched isn't very
-selective\(emmany glyphs are placed in both regular and special fonts.
-Normally, the
-.B \-a
-option should be used only as a last resort.
-.\" --------------------------------------------------------------------------
-.TP
-.B \-d
-Dump information about the TFM file to the standard output; this option
-can be useful for ensuring that a TFM file is a proper match for a font,
-and that the contents of the TFM file are suitable.
-The information includes the values of important TFM tags, and a listing
-(by MSL number for Intellifont TFM files or by Unicode value for
-TrueType TFM files) of the glyphs included in the TFM file.
-The unit of measure `DU' for some tags indicates design units; there are
-8782 design units per em for Intellifont fonts, and 2048 design units
-per em for TrueType fonts.
-Note that the accessibility of a glyph depends on its inclusion in a
-symbol set; some TFM files list many glyphs but only a few symbol sets.
-.IP
-The glyph listing includes the glyph index within the TFM file, the MSL
-or Unicode value, and the symbol set and character code that will be
-used to print the glyph.
-If
-.I map_file
-is given,
-groff names are given for matching glyphs.
-If only the glyph index and MSL or Unicode value are given, the glyph
-does not appear in any supported symbol set and cannot be printed.
-.IP
-With the
-.B \-d
-option,
-.I map_file
-is optional, and
-.I font
-is ignored if given.
-.\" --------------------------------------------------------------------------
-.TP
-.B \-q
-Suppress warnings about characters in the map file that were not found
-in the TFM file.
-Warnings never are given for unnamed glyphs or by glyphs named by their
-Unicode values.
-This option is useful when sending the output of
-.B hpftodit
-to the standard output.
-.\" --------------------------------------------------------------------------
-.TP
-.B \-v
-Print the
-.B hpftodit
-version number.
-.\" --------------------------------------------------------------------------
-.TP
-.B \-s
-The font is special.
-This option adds the
-.B special
-command to the font file, and affects the order in which HP symbol sets
-are searched for each glyph.
-Without the
-.B \-s
-option, the \(lqtext\(rq sets are searched before
-the \(lqmathematical\(rq symbol sets.
-With the
-.B \-s
-option, the search order is reversed.
-.\" --------------------------------------------------------------------------
-.TP
-.BI \-i n
-Generate an italic correction for each character so that the character's
-width plus the character's italic correction is equal to
-.I n
-thousandths of an em plus the amount by which the right edge of the
-character's bounding is to the right of the character's origin.
-If this would result in a negative italic correction, use a zero italic
-correction instead.
-.IP
-Also generate a subscript correction equal to the 
-product of the tangent of the slant of the font and
-four fifths of the x-height of the font.
-If this would result in a subscript correction greater than the italic
-correction, use a subscript correction equal to the italic correction
-instead.
-.IP
-Also generate a left italic correction for each character
-equal to
-.I n
-thousandths of an em plus the amount by which the left edge of the
-character's bounding box is to the left of the character's origin.
-The left italic correction may be negative.
-.IP
-This option normally is needed only with italic or oblique fonts;
-a value of 50 (0.05 em) usually is a reasonable choice.

-.SH DESCRIPTION
-.B @g@indxbib
-makes an inverted index for the bibliographic databases in
-.IR filename \|.\|.\|.
-for use with
-.BR @g@refer (@MAN1EXT@),
-.BR @g@lookbib (@MAN1EXT@),
-and
-.BR lkbib (@MAN1EXT@).
-The index will be named
-.IB filename @INDEX_SUFFIX@\fR;
-the index is written to a temporary file which is then renamed to this.
-If no filenames are given on the command line because the
-.B \-f
-option has been used, and no
-.B \-o
-option is given, the index will be named
-.BR @DEFAULT_INDEX_NAME@@INDEX_SUFFIX@ .
-.LP
-Bibliographic databases are divided into records by blank lines.
-Within a record, each fields starts with a
-.B %
-character at the beginning of a line.
-Fields have a one letter name which follows the
-.B %
-character.
-.LP
-The values set by the
-.BR \-c ,
-.BR \-n ,
-.BR \-l
-and
-.B \-t
-options are stored in the index;
-when the index is searched, keys will be discarded and truncated in a
-manner appropriate to these options;
-the original keys will be used for verifying that any record
-found using the index actually contains the keys.
-This means that a user of an index need not know whether these
-options were used in the creation of the index,
-provided that not all the keys to be searched for
-would have been discarded during indexing
-and that the user supplies at least the part of each key
-that would have remained after being truncated during indexing.
-The value set by the
-.B \-i
-option is also stored in the index
-and will be used in verifying records found using the index.
-.SH OPTIONS
-.TP
-.B \-v
-Print the version number.
-.TP
-.B \-w
-Index whole files.
-Each file is a separate record.
-.TP
-.BI \-c file
-Read the list of common words from
-.I file
-instead of
-.BR @COMMON_WORDS_FILE@ .
-.TP
-.BI \-d dir
-Use
-.I dir
-as the pathname of the current working directory to store in the index,
-instead of the path printed by
-.BR pwd (1).
-Usually
-.I dir
-will be a symbolic link that points to the directory printed by
-.BR pwd (1).
-.TP
-.BI \-f file
-Read the files to be indexed from
-.IR file .
-If
-.I file
-is
-.BR \- ,
-files will be read from the standard input.
-The
-.B \-f
-option can be given at most once.
-.TP
-.BI \-i string
-Don't index the contents of fields whose names are in
-.IR string .
-Initially
-.I string
-is
-.BR XYZ .
-.TP
-.BI \-h n
-Use the first prime greater than or equal to
-.I n
-for the size of the hash table.
-Larger values of
-.I n
-will usually make searching faster,
-but will make the index larger
-and
-.B @g@indxbib
-use more memory.
-Initially
-.I n
-is 997.
-.TP
-.BI \-k n
-Use at most
-.I n
-keys per input record.
-Initially
-.I n
-is 100.
-.TP
-.BI \-l n
-Discard keys that are shorter than
-.IR n .
-Initially
-.I n
-is 3.
-.TP
-.BI \-n n
-Discard the
-.I n
-most common words.
-Initially
-.I n
-is 100.
-.TP
-.BI \-o basename
-The index should be named
-.IB basename @INDEX_SUFFIX@\fR.
-.TP
-.BI \-t n
-Truncate keys to
-.IR n .
-Initially
-.I n
-is 6.
-.SH FILES
-.TP \w'\fBindxbib\fIXXXXXX'u+2n
-.IB filename @INDEX_SUFFIX@
-Index.
-.TP
-.B @DEFAULT_INDEX_NAME@@INDEX_SUFFIX@
-Default index name.
-.TP
-.B @COMMON_WORDS_FILE@
-List of common words.

-.SH DESCRIPTION
-.B lkbib
-searches bibliographic databases for references that contain the keys
-.IR key \|.\|.\|.\&
-and prints any references found on the standard output.
-.B lkbib
-will search any databases given by

-options, and then a default database.
-The default database is taken from the
-.SB REFER
-environment variable if it is set,
-otherwise it is
-.BR @DEFAULT_INDEX@ .
-For each database
-.I filename
-to be searched,
-if an index
-.IB filename @INDEX_SUFFIX@
-created by
-.BR @g@indxbib (@MAN1EXT@)
-exists, then it will be searched instead;
-each index can cover multiple databases.
-.
-.
-.SH OPTIONS

-.SH DESCRIPTION
-.B pfbtops
-translates a PostScript font in
-.B .pfb
-format to ASCII, splitting overlong lines in text packets into smaller
-chunks.
-If
-.I pfb_file
-is omitted the pfb file will be read from the standard input.
-The ASCII format PostScript font will be written on the standard output.
-PostScript fonts for MS-DOS are normally supplied in
-.B .pfb
-format.
-.
-.LP
-The resulting ASCII format PostScript font can be used with groff.
-It must first be listed in
-.BR @FONTDIR@/devps/download .
-.
-.SH OPTIONS
-.TP
-.B \-v
-Print the version number.

-/* I have tried to incorporate the changes needed for TeX 3.0 tfm files,
-but I haven't tested them. */
-
-/* Groff requires more font metric information than TeX.  The reason
-for this is that TeX has separate Math Italic fonts, whereas groff
-uses normal italic fonts for math.  The two additional pieces of
-information required by groff correspond to the two arguments to the
-math_fit() macro in the Metafont programs for the CM fonts. In the
-case of a font for which math_fitting is false, these two arguments
-are normally ignored by Metafont. We need to get hold of these two
-parameters and put them in the groff font file.
-
-We do this by loading this definition after cmbase when creating cm.base.
-
-def ignore_math_fit(expr left_adjustment,right_adjustment) =
- special "adjustment";
- numspecial left_adjustment*16/designsize;
- numspecial right_adjustment*16/designsize;
- enddef;
-
-This puts the two arguments to the math_fit macro into the gf file.
-(They will appear in the gf file immediately before the character to
-which they apply.)  We then create a gf file using this cm.base.  Then
-we run tfmtodit and specify this gf file with the -g option.
-
-This need only be done for a font for which math_fitting is false;
-When it's true, the left_correction and subscript_correction should
-both be zero. */

-.SH DESCRIPTION
-.B tfmtodit
-creates a font file for use with
-.B
-groff \-Tdvi\fR.
-.I tfm_file
-is the name of the \*(tx font metric file for the font.
-.I map_file
-is a file giving the groff names for characters in the font;
-this file should consist of a sequence of lines of the form:
-.IP
-.I
-n c1 c2 \fR.\|.\|.
-.LP
-where
-.I n
-is a decimal integer giving the position of the character in the font,
-and
-.IR c1 ,
-.IR c2 ,.\|.\|.
-are the groff names of the character.
-If a character has no groff names but exists in the tfm file,
-then it will be put in the groff font file as an unnamed character.
-.I font
-is the name of the groff font file.
-The groff font file is written to
-.IR font .
-.LP
-The
-.B \-s
-option should be given if the font is special
-(a font is
-.I special
-if
-.B troff
-should search it whenever
-a character is not found in the current font.)
-If the font is special,
-it should be listed in the
-.B fonts
-command in the DESC file;
-if it is not special, there is no need to list it, since
-.B troff
-can automatically mount it when it's first used.
-.LP
-To do a good job of math typesetting, groff requires
-font metric information not present in the tfm file.
-The reason for this is that \*(tx has separate math italic fonts
-whereas groff uses normal italic fonts for math.
-The additional information required by groff is given by the
-two arguments to the
-.B math_fit
-macro in the Metafont programs for the Computer Modern fonts.
-In a text font (a font for which
-.B math_fitting
-is false), Metafont normally ignores these two arguments.
-Metafont can be made to put this information in the gf file
-by loading the following definition after
-.B cmbase
-when creating
-.BR cm.base :
-.IP
-.nf
-.ft B
-def ignore_math_fit(expr left_adjustment,right_adjustment) =
-    special "adjustment";
-    numspecial left_adjustment*16/designsize;
-    numspecial right_adjustment*16/designsize;
-    enddef;
-.fi
-.ft R
-.LP
-For the EC font family, load the following definition after
-.B exbase
-(it is probably easiest to patch
-.B exbase.mf
-locally):
-.IP
-.nf
-.ft B
-def ignore_math_fit(expr left_adjustment,right_adjustment) =
-    ori_special "adjustment";
-    ori_numspecial left_adjustment*16/designsize;
-    ori_numspecial right_adjustment*16/designsize;
-    enddef;
-.fi
-.ft R
-.LP
-The gf file created using this modified
-.B cm.base
-or
-.B exbase
-should be specified with the
-.B \-g
-option.
-The
-.B \-g
-option should not be given for a font for which
-.B math_fitting
-is true.
-.SH OPTIONS
-.TP
-.B \-v
-Print the version number.
-.TP
-.B \-s
-The font is special.
-The effect of this option is to add the
-.B special
-command to the font file.
-.TP
-.BI \-k n
-The skewchar of this font is at position
-.IR n .
-.I n
-should be an integer;
-it may be given in decimal,
-or with a leading 
-.B 0
-in octal,
-or with a leading
-.B 0x
-in hexadecimal.
-The effect of this option is to ignore any kerns whose second component
-is the specified character.
-.TP
-.BI \-g gf_file
-.I gf_file
-is a gf file produced by Metafont containing special and numspecial
-commands giving additional font metric information.
-.SH FILES

-.TH XTOTROFF @MAN1EXT@ "@MDATE@" "Groff Version @VERSION@"
-.
-.
-.SH NAME
-xtotroff \- convert X font metrics into GNU troff font metrics
-.
-.
-.SH SYNOPSIS
-.B xtotroff
-[
-.BI \-r \%resolution
-]
-[
-.BI \-s \%point-size
-]
-[
-.B \-v
-]
-.I FontMap
-.
-.PP
-It is possible to have whitespace between a command line option and its
-parameter.
-.
-.
-.SH DESCRIPTION
-.B xtotroff
-takes a
-.IR FontMap ,
-which maps
-.B groff
-fonts to X11 fonts,
-creates GNU
-.B troff
-metric files for all fonts listed.
-Each line in
-.I FontMap
-consists of GNU
-.B troff
-font name and an X font name (XLFD) pattern, separated by whitespace.
-Example:
-.
-.PP
-.in +2n
-.nf
-TB   -adobe-times-bold-r-normal--*-*-*-*-p-*-iso8859-1
-.fi
-.in
-.
-.PP
-The wildcards in the patterns are filled with the arguments to the
-.B \-r
-and
-.B \-s
-switches.
-If a font name is still ambiguous,
-.B xtotroff
-aborts.
-.
-.
-.SH OPTIONS
-.TP
-.BI \-r resolution
-Set the resolution for all font patterns in
-.IR FontMap .
-The value is used for both the horizontal and vertical resolution.
-If not specified, a resolution of 75dpi is assumed.
-.
-.TP
-.BI \-s point-size
-Set the point size for all font patterns in
-.IR FontMap .
-If not specified, a size of 10pt is assumed.
-.
-.TP
-.B \-v
-Print the version number.
-.
-.
-.SH BUGS
-The only supported font encodings are `iso8859-1' and `adobe-fontspecific'.

-    Description
-------------------------------------------------------------------------
-
-A simple set of macros to provide markup devices (currently only grohtml)
-with tags that define the meaning of the formatted text and also
-basic formatting instructions.  It generalizes the tag concept used within
-grohtml and in the future it is hoped that more markup based devices
-can capitalize on this work.  It also clearly defines those tags which are
-honoured by grohtml.  Note that not all tags are included here.  Some
-of the grohtml specific tags (header specific and jobname, etc.) are
-called directly from within www.tmac.  The tags defined here are
-reasonably generic and could be applied to other devices.

-.\" -----------------------------------------------------------------
-.
-.SH DESCRIPTION
-.
-The
-.B man
-macros used to generate
-.I \%man\~pages
-with
-.I groff
-were written by James Clark.
-.
-This document provides a brief summary of the use of each macro in that
-package.
-.
-.
-.\" -----------------------------------------------------------------
-.
-.SH OPTIONS
-.
-The
-.B man
-macros understand the following command line options (which define
-various registers).
-.
-.TP
-.B \-rcR=1
-This option (the default if in nroff mode) will create a single, very
-long page instead of multiple pages.
-.
-Say
-.B \-rcR=0
-to disable it.
-.
-.TP
-.B \-rC1
-If more than one manual page is given on the command line, number the
-pages continuously, rather than starting each at\ 1.
-.
-.TP
-.B \-rD1
-Double-sided printing.
-.
-Footers for even and odd pages are formatted differently.
-.
-.TP
-.BI \-rFT= dist
-Set distance of the footer relative to the bottom of the page if
-negative or relative to the top if positive.
-.
-The default is -0.5i.
-.
-.TP
-.BI \-rHY= flags
-Set hyphenation flags.
-.
-Possible values are 1\ to hyphenate without restrictions, 2\ to not
-hyphenate the last word on a page, 4\ to not hyphenate the last two
-characters of a word, and 8\ to not hyphenate the first two characters
-of a word.
-.
-These values are additive; the default is\ 14.
-.
-.TP
-.BI \-rIN= width
-Set body text indentation to
-.IR width .
-The default is 7n for
-.IR nroff ,
-7.2n for
-.IR troff .
-For
-.IR nroff ,
-this value should always be an integer multiple of unit `n' to get
-consistent indentation.
-.
-.TP
-.BI \-rLL= line-length
-Set line length.
-.
-If this option is not given,
-the line length is set to respect any value set by a prior `.ll' request,
-(which
-.I must
-be in effect when the `.TH' macro is invoked),
-if this differs from the built\-in default for the formatter;
-otherwise it defaults to 78n in
-.I nroff
-mode and 6.5i in
-.I troff
-mode.
-.
-.IP
-Note that the use of a `.ll' request to initialize the line length
-is supported for backward compatibility with some versions of the
-.B man
-program;
-direct initialization of the `LL' register should
-.I always
-be preferred to the use of such a request.
-In particular, note that a `.ll\ 65n' request will
-.I not
-preserve the normal
-.I nroff
-default line length,
-(the
-.B man
-default initialization to 78n will prevail),
-whereas,
-the `-rLL=65n' option, or an equivalent `.nr\ LL\ 65n'
-request preceding the use of the `TH' macro,
-.I will
-set a line length of 65n.
-.
-.TP
-.BI \-rLT= title-length
-Set title length.
-.
-If this option is not given, the title length defaults to the line
-length.
-.
-.TP
-.BI \-rP nnn
-Enumeration of pages will start with
-.I nnn
-rather than with\ 1.
-.
-.TP
-.BI \-rS xx
-Base document font size is
-.I xx
-points
-.RI ( xx
-can be 10, 11, or\ 12) rather than 10\ points.
-.
-.TP
-.BI \-rSN= width
-Set sub-subheading indentation to
-.IR width .
-The default is 3n.
-.
-.TP
-.BI \-rX nnn
-After page\ \c
-.IR nnn ,
-number pages as
-.IR nnn a,
-.IR nnn b,
-.IR nnn c,
-etc.
-.
-For example, the option `\-rX2' will produce the following page
-numbers: 1, 2, 2a, 2b, 2c, etc.
-.
-.
-.\" -----------------------------------------------------------------
-.
-.SH USAGE
-.
-This section describes the available macros for manual pages.
-.
-For further customization, put additional macros and requests into the
-file
-.B man.local
-which will be loaded immediately after the
-.B man
-package.
-.
-.TP
-.BI .TH " title section \fB[\fPextra1\fB]\fP \fB[\fPextra2\fB]\fP \fB[\fPextra3\fB]"
-Set the title of the
-.I \man\~page
-to
-.I title
-and the section to
-.IR section ,
-which must take on a value between 1 and\ 8.
-.
-The value
-.I section
-may also have a string appended, e.g. `.pm', to indicate a specific
-subsection of the
-.IR \%man\~pages .
-Both
-.I title
-and
-.I section
-are positioned at the left and right in the header line (with
-.I section
-in parentheses immediately appended to
-.IR title .
-.I extra1
-will be positioned in the middle of the footer line.
-.I extra2
-will be positioned at the left in the footer line (or at the left on
-even pages and at the right on odd pages if double-sided printing is
-active).
-.I extra3
-is centered in the header line.
-.
-.IP
-For HTML output, headers and footers are completely supressed.
-.
-.IP
-Additionally, this macro starts a new page; the new line number is\ 1
-again (except if the `-rC1' option is given on the command line) --
-this feature is intended only for formatting multiple
-.IR \%man\~pages ;
-a single
-.I \%man\~page
-should contain exactly one
-.B TH
-macro at the beginning of the file.
-.
-.TP
-.BI ".SH [" "text for a heading" ]
-Set up an unnumbered section heading sticking out to the left.
-.
-Prints out all the text following
-.B SH
-up to the end of the line (or the text in the next input line if there
-is no argument to
-.BR SH )
-in bold face
-(or the font specified by the string
-.BR HF ),
-one size larger than the base document size.
-.
-Additionally, the left margin and the indentation for the following
-text is reset to the default values.
-.
-.TP
-.BI ".SS [" "text for a heading" ]
-Set up a secondary, unnumbered section heading.
-.
-Prints out all the text following
-.B SS
-up to the end of the line (or the text in the next input line if there
-is no argument to
-.BR SS )
-in bold face
-(or the font specified by the string
-.BR HF ),
-at the same size as the base document size.
-.
-Additionally, the left margin and the indentation for the following
-text is reset to the default values.
-.
-.TP
-.BI ".TP [" nnn ]
-Set up an indented paragraph with label.
-.
-The indentation is set to
-.I nnn
-if that argument is supplied (the default unit is `n' if omitted),
-otherwise it is set to the previous indentation value specified with
-.BR TP ,
-.BR IP ,
-or
-.B HP
-(or to the default value if none of them have been used yet).
-.
-.IP
-The first input line of text following this macro is interpreted as a
-string to be printed flush-left, as it is appropriate for a label.
-.
-It is not interpreted as part of a paragraph, so there is no attempt
-to fill the first line with text from the following input lines.
-.
-Nevertheless, if the label is not as wide as the indentation the
-paragraph starts at the same line (but indented), continuing on the
-following lines.
-.
-If the label is wider than the indentation the descriptive part of the
-paragraph begins on the line following the label, entirely indented.
-.
-Note that neither font shape nor font size of the label is set to a
-default value; on the other hand, the rest of the text will have
-default font settings.
-.
-.IP
-The
-.B TP
-macro is the macro used for the explanations you are just reading.
-.
-.TP
-.B .LP
-.TQ
-.B .PP
-.TQ
-.B .P
-These macros are mutual aliases.
-.
-Any of them causes a line break at the current position, followed by a
-vertical space downwards by the amount specified by the
-.B PD
-macro.
-.
-The font size and shape are reset to the default value (10pt
-resp. Roman).
-.
-Finally, the current left margin and the indentation are restored.
-.
-.TP
-.BI ".IP [" designator "] [" nnn ]
-Set up an indented paragraph, using
-.I designator
-as a tag to mark its beginning.
-.
-The indentation is set to
-.I nnn
-if that argument is supplied (the default unit is `n' if omitted),
-otherwise it is set to the previous indentation value specified with
-.BR TP ,
-.BR IP ,
-or
-.B HP
-(or to the default value if none of them have been used yet).
-.
-Font size and face of the paragraph (but not the designator) are reset
-to its default values.
-.
-.IP
-To start an indented paragraph with a particular indentation but
-without a designator, use `""' (two doublequotes) as the second
-argument.
-.
-.IP
-For example, the following paragraphs were all set up with bullets as
-the designator, using `.IP\ \\(bu\ 4'.
-.
-The whole block has been enclosed with `.RS' and `.RE' to set the left
-margin temporarily to the current indentation value.
-.
-.RS
-.IP \(bu 4
-.B IP
-is one of the three macros used in the
-.B man
-package to format lists.
-.IP \(bu 4
-.B HP
-is another.
-.
-This macro produces a paragraph with a left hanging indentation.
-.IP \(bu 4
-.B TP
-is another.
-.
-This macro produces an unindented label followed by an indented
-paragraph.
-.RE
-.
-.TP
-.BI ".HP [" nnn ]
-Set up a paragraph with hanging left indentation.
-.
-The indentation is set to
-.I nnn
-if that argument is supplied (the default unit is `n' if omitted),
-otherwise it is set to the previous indentation value specified with
-.BR TP ,
-.BR IP ,
-or
-.B HP
-(or to the default value if none of them have been used yet).
-.
-Font size and face are reset to its default values.
-.
-The following paragraph illustrates the effect of this macro with
-hanging indentation set to\ 4 (enclosed by
-.B .RS
-and
-.B .RE
-to set the left margin temporarily to the current indentation):
-.
-.RS
-.HP 4
-This is a paragraph following an invocation of the
-.B HP
-macro.
-.
-As you can see, it produces a paragraph where all lines but the first
-are indented.
-.RE
-.
-.TP
-.BI ".RS [" nnn ]
-This macro moves the left margin to the right by the value
-.I nnn
-if specified (default unit is `n'); otherwise it is set to the
-previous indentation value specified with
-.BR TP ,
-.BR IP ,
-or
-.B HP
-(or to the default value if none of them have been used yet).
-.
-The indentation value is then set to the default.
-.
-.IP
-Calls to the
-.B RS
-macro can be nested.
-.
-.TP
-.BI ".RE [" nnn ]
-This macro moves the left margin back to level
-.IR nnn ,
-restoring the previous left margin.
-.
-If no argument is given, it moves one level back.
-.
-The first level (i.e., no call to
-.B RS
-yet) has number\ 1, and each call to
-.B RS
-increases the level by\ 1.
-.
-.PP
-To summarize, the following macros cause a line break with the
-insertion of vertical space (which amount can be changed with the
-.B PD
-macro):
-.BR SH ,
-.BR SS ,
-.BR TP ,
-.B LP
-.RB ( PP ,
-.BR P ),
-.BR IP ,
-and
-.BR HP .
-The macros
-.B RS
-and
-.B RE
-also cause a break but no insertion of vertical space.
-.
-.

-.
-.SH "MACROS TO SET FONTS"
-.
-The standard font is Roman; the default text size is 10\ point.
-.
-.TP
-.BI ".SM [" text ]
-Causes the text on the same line or the text on the next input line to
-appear in a font that is one point size smaller than the default font.
-.
-.TP
-.BI ".SB [" text ]
-Causes the text on the same line or the text on the next input line to
-appear in boldface font, one point size smaller than the default font.
-.
-.TP
-.BI ".BI " text
-Causes text on the same line to appear alternately in bold face and
-italic.
-.
-The text must be on the same line as the macro call.
-.
-Thus
-.RS
-.IP
-\&.BI this "word and" that
-.PP
-would cause `this' and `that' to appear in bold face, while `word and'
-appears in italics.
-.RE
-.
-.TP
-.BI ".IB " text
-Causes text to appear alternately in italic and bold face.
-.
-The text must be on the same line as the macro call.
-.
-.TP
-.BI ".RI " text
-Causes text on the same line to appear alternately in roman and
-italic.
-.
-The text must be on the same line as the macro call.
-.
-.TP
-.BI ".IR " text
-Causes text on the same line to appear alternately in italic and
-roman.
-.
-The text must be on the same line as the macro call.
-.
-.TP
-.BI ".BR " text
-Causes text on the same line to appear alternately in bold face and
-roman.
-.
-The text must be on the same line as the macro call.
-.
-.TP
-.BI ".RB " text
-Causes text on the same line to appear alternately in roman and bold
-face.
-.
-The text must be on the same line as the macro call.
-.
-.TP
-.BI ".B [" text ]
-Causes
-.I text
-to appear in bold face.
-.
-If no text is present on the line where the macro is called the text
-of the next input line appears in bold face.
-.
-.TP
-.BI ".I [" text ]
-Causes
-.I text
-to appear in italic.
-.
-If no text is present on the line where the macro is called the text
-of the next input line appears in italic.
-.
-.
-.\" -----------------------------------------------------------------
-.
-.SH "MISCELLANEOUS"
-.
-The default indentation is 7.2n in troff mode and 7n in nroff mode
-except for
-.B grohtml
-which ignores indentation.
-.
-.TP
-.B .DT
-Set tabs every 0.5 inches.
-.
-Since this macro is always called during a

-changed.
-.
-.TP
-.BI ".PD [" nnn ]
-Adjust the empty space before a new paragraph or section.
-.
-The optional argument gives the amount of space (default unit is `v');

-.
-.Nm groff Fl m Ns Cm doc Ar
-.
-.
-.Sh DESCRIPTION
-.
-A complete reference for writing
-.Ux
-manual pages with the
-.Nm \-mdoc
-macro package; a
-.Em content Ns -based
-and
-.Em domain Ns -based
-formatting package for
-.Tn GNU
-.Xr troff 1 .
-Its predecessor, the
-.Xr \-man 7
-package, addressed page layout leaving the manipulation of fonts and other
-typesetting details to the individual author.
-In
-.Nm \-mdoc ,
-page layout macros make up the
-.Em "page structure domain"
-which consists of macros for titles, section headers, displays and lists
-\- essentially items which affect the physical position of text on a
-formatted page.
-In addition to the page structure domain, there are two more domains, the
-.Em manual
-domain and the
-.Em general
-text domain.
-The general text domain is defined as macros which perform tasks such as
-quoting or emphasizing pieces of text.
-The manual domain is defined as macros that are a subset of the day to day
-informal language used to describe commands, routines and related
-.Ux
-files.
-Macros in the manual domain handle command names, command line arguments and
-options, function names, function parameters, pathnames, variables, cross
-references to other manual pages, and so on.
-These domain items have value for both the author and the future user of the
-manual page.
-Hopefully, the consistency gained across the manual set will provide easier
-translation to future documentation tools.
-.Pp
-Throughout the
-.Ux
-manual pages, a manual entry is simply referred to as a man page, regardless
-of actual length and without sexist intention.

-.Sh "TROFF IDIOSYNCRASIES"
-.
-The
-.Nm \-mdoc
-package attempts to simplify the process of writing a man page.
-Theoretically, one should not have to learn the tricky details of
-.Tn GNU
-.Xr troff 1
-to use
-.Nm \-mdoc ;
-however, there are a few limitations which are unavoidable and best gotten
-out of the way.
-And, too, be forewarned, this package is
-.Em not
-fast.
-.
-.Ss "Macro Usage"
-.
-As in
-.Tn GNU
-.Xr troff 1 ,
-a macro is called by placing a
-.Ql .\&
-(dot character) at the beginning of a line followed by the two-character
-(or three-character) name for the macro.
-There can be space or tab characters between the dot and the macro name.
-Arguments may follow the macro separated by spaces (but
-.Em no
-tabs).
-It is the dot character at the beginning of the line which causes
-.Tn GNU
-.Xr troff 1
-to interpret the next two (or more) characters as a macro name.
-A single starting dot followed by nothing is ignored.
-To place a
-.Ql .\&
-(dot character) at the beginning of an input line in some context other than
-a macro invocation, precede the
-.Ql .\&
-(dot) with the
-.Ql \e&
-escape sequence which translates literally to a zero-width space, and is
-never displayed in the output.
-.Pp
-In general,
-.Tn GNU
-.Xr troff 1
-macros accept an unlimited number of arguments (contrary to other versions
-of troff which can't handle more than nine arguments).
-In limited cases, arguments may be continued or extended on the next
-line (See
-.Sx Extended Arguments
-below).
-Almost all macros handle quoted arguments (see
-.Sx Passing Space Characters in an Argument
-below).
-.Pp
-Most of the
-.Nm \-mdoc
-general text domain and manual domain macros are special in that their
-argument lists are
-.Em parsed
-for callable macro names.
-This means an argument on the argument list which matches a general text or
-manual domain macro name (and which is defined to be callable) will be
-executed or called when it is processed.
-In this case the argument, although the name of a macro, is not preceded by
-a
-.Ql .\&
-(dot).
-This makes it possible to nest macros; for example the option macro,
-.Ql .Op ,
-may
-.Em call
-the flag and argument macros,
-.Ql \&Fl
-and
-.Ql \&Ar ,
-to specify an optional flag with an argument:
-.
-.Bl -tag -width ".Op Fl s Ar bytes" -offset indent
-.It Op Fl s Ar bytes
-is produced by
-.Ql ".Op Fl s Ar bytes"
-.El
-.
-.Pp
-To prevent a string from being interpreted as a macro name, precede the
-string with the escape sequence
-.Ql \e& :
-.
-.Bl -tag -width ".Op \&Fl s \&Ar bytes" -offset indent
-.It Op \&Fl s \&Ar bytes
-is produced by
-.Ql ".Op \e&Fl s \e&Ar bytes"
-.El
-.
-.Pp
-Here the strings
-.Ql \&Fl
-and
-.Ql \&Ar
-are not interpreted as macros.
-Macros whose argument lists are parsed for callable arguments are referred
-to as
-.Em parsed
-and macros which may be called from an argument list are referred to as
-.Em callable
-throughout this document.
-This is a technical
-.Em faux pas
-as almost all of the macros in
-.Nm \-mdoc
-are parsed, but as it was cumbersome to constantly refer to macros as
-being callable and being able to call other macros, the term parsed
-has been used.
-.
-.Pp
-In the following, we call an
-.Nm \-mdoc
-macro which starts a line (with a leading dot) a
-.Em command
-if this distinction is necessary.
-.
-.Ss "Passing Space Characters in an Argument"
-.
-Sometimes it is desirable to give as an argument a string containing one or
-more blank space characters, say, to specify arguments to commands which
-expect particular arrangement of items in the argument list.
-Additionally, it makes
-.Nm \-mdoc
-working faster.
-For example, the function command
-.Ql .Fn
-expects the first argument to be the name of a function and any remaining
-arguments to be function parameters.
-As
-.Tn ANSI\~C
-stipulates the declaration of function parameters in the parenthesized
-parameter list, each parameter is guaranteed to be at minimum a two word
-string.
-For example,
-.Fa int foo .
-.Pp
-There are two possible ways to pass an argument which contains
-an embedded space.
-One way of passing a string containing blank spaces is to use the hard or
-unpaddable space character
-.Ql \e\  ,
-that is, a blank space preceded by the escape character
-.Ql \e .
-This method may be used with any macro but has the side effect of
-interfering with the adjustment of text over the length of a line.
-.Xr Troff
-sees the hard space as if it were any other printable character and cannot
-split the string into blank or newline separated pieces as one would expect.
-This method is useful for strings which are not expected to overlap a line
-boundary.
-An alternative is to use
-.Ql \e~ ,
-a paddable (i.e.\& stretchable), unbreakable space (this is a
-.Tn GNU
-.Xr troff 1
-extension).
-The second method is to enclose the string with double quotes.
-.Pp
-For example:
-.
-.Bl -tag -width ".Fn fetch char\ *str" -offset indent
-.It Fn fetch char\ *str
-is created by
-.Ql ".Fn fetch char\e *str"
-.It Fn fetch "char *str"
-can also be created by
-.Ql ".Fn fetch \*[q]char *str\*[q]"
-.El
-.
-.Pp
-If the
-.Ql \e
-before the space in the first example
-or double quotes in the second example
-were omitted,
-.Ql .Fn
-would see three arguments, and the result would be:
-.Pp
-.Dl Fn fetch char *str
-.Pp
-.\" For an example of what happens when the parameter list overlaps a newline
-.\" boundary, see the
-.\" .Sx BUGS
-.\" section.
-.
-.Ss "Trailing Blank Space Characters"
-.
-.Xr Troff
-can be confused by blank space characters at the end of a line.
-It is a wise preventive measure to globally remove all blank spaces
-from
-.Ao blank-space Ac Ns Ao end-of-line Ac
-character sequences.
-Should the need arise to use a blank character at the end of a line, it
-may be forced with an unpaddable space and the
-.Ql \e&
-escape character.
-For example,
-.Ql string\e\ \e& .
-.
-.Ss "Escaping Special Characters"
-.
-Special characters like the newline character
-.Ql \en
-are handled by replacing the
-.Ql \e
-with
-.Ql \ee
-(e.g.\&
-.Ql \een )
-to preserve the backslash.
-.
-.Ss "Other Possible Pitfalls"
-.
-A warning is emitted when an empty input line is found outside of displays
-(see below).
-Use
-.Ql .sp
-instead.
-(Well, it is even better to use
-.Nm \-mdoc
-macros to avoid the usage of low-level commands.)
-.Pp
-Leading spaces will cause a break and are output directly.
-Avoid this behaviour if possible.
-Similarly, do not use more than one space character between words in an
-ordinary text line; contrary to other text formatters, they are
-.Em not
-replaced with a single space.
-.Pp
-You can't pass
-.Ql \*[q]
-directly as an argument.
-Use
-.Ql \e*[q]
-(or
-.Ql \e*q )
-instead.
-.Pp
-By default,
-.Xr troff 1
-inserts two space characters after a punctuation mark closing a sentence;
-characters like
-.Ql \&)
-or
-.Ql \&'
-are treated transparently, not influencing the sentence-ending behaviour.
-To change this, insert
-.Ql \e&
-before or after the dot:
-.
-.Bd -literal -offset indent
-The
-\&.Ql .
-character.
-\&.Pp
-The
-\&.Ql \e&.
-character.

-character
-.Pp
-The
-.Ql \&.
-character.
-.Pp
-.No test .
-test
-.Pp
-.No test.
-test
-.Ed
-.Pp
-.
-As can be seen in the first and third line,
-.Nm \-mdoc
-handles punctuation characters specially in macro arguments.
-This will be explained in section
-.Sx General Syntax
-below.
-In the same way, you have to protect trailing full stops of abbreviations
-with a trailing zero-width space:
-.Ql e.g.\e& .
-.Pp
-A comment in the source file of a man page can be either started with
-.Ql .\e"
-on a single line,
-.Ql \e"
-after some input, or
-.Ql \e#
-anywhere (the latter is a
-.Tn GNU
-.Xr troff 1
-extension); the rest of such a line is ignored.
-.
-.
-.Sh "A MANUAL PAGE TEMPLATE"
-.
-The body of a man page is easily constructed from a basic template:
-.
-.Bd -literal -offset indent

-.Pp
-.
-The first items in the template are the commands
-.Ql .Dd ,
-.Ql .Dt ,
-and
-.Ql .Os ;
-the document date, the operating system the man page or subject source is
-developed or modified for, and the man page title (in
-.Em upper case )
-along with the section of the manual the page belongs in.
-These commands identify the page and are discussed below in
-.Sx TITLE MACROS .
-.Pp
-The remaining items in the template are section headers
-.Pf ( Li .Sh ) ;
-of which
-.Em NAME ,
-.Em SYNOPSIS ,
-and
-.Em DESCRIPTION
-are mandatory.
-The headers are discussed in
-.Sx "PAGE STRUCTURE DOMAIN" ,
-after presentation of
-.Sx "MANUAL DOMAIN" .
-Several content macros are used to demonstrate page layout macros; reading
-about content macros before page layout macros is recommended.
-.
-.
-.Sh CONVENTIONS
-.
-In the description of all macros below, optional arguments are put into
-brackets.
-An ellipsis
-.Pf ( Sq ... )
-represents zero or more additional arguments.
-Alternative values for a parameter are separated with
-.Ql | .
-If there are alternative values for a mandatory parameter, braces are used
-(together with
-.Ql | )
-to enclose the value set.
-Meta-variables are specified within angles.
-.Pp
-Example:
-.
-.Bl -tag -width 6n -offset indent
-.It Li .Xx Xo
-.Aq foo 
-.Brq bar1 | bar2
-.Op \-test1 Op \-test2 | \-test3
-.No ...
-.Xc
-.El
-.
-.Pp
-Except stated explicitly, all macros are parsed and callable.
-.Pp
-Note that a macro takes effect up to the next nested macro.
-For example,
-.Ql ".Ic foo Aq bar"
-doesn't produce
-.Sq Ic "foo <bar>"
-but
-.Sq Ic foo Aq bar .
-Consequently, a warning message is emitted for most commands if the first
-argument is a macro itself since it cancels the effect of the calling
-command completely.
-Another consequence is that quoting macros never insert literal quotes;
-.Sq Ic "foo <bar>"
-has been produced by
-.Ql ".Ic \*[q]foo <bar>\*[q]" .
-.Pp
-Most macros have a default width value which can be used to specify a label
-width
-.Pf ( Fl width )
-or offset
-.Pf ( Fl offset )
-for the
-.Ql .Bl
-and
-.Ql .Bd
-macros.
-It is recommended not to use this rather obscure feature to avoid
-dependencies on local modifications of the
-.Nm \-mdoc
-package.
-.
-.
-.Sh "TITLE MACROS"
-.
-The title macros are part of the page structure domain but are presented
-first and separately for someone who wishes to start writing a man page
-yesterday.
-Three header macros designate the document title or manual page title, the
-operating system, and the date of authorship.
-These macros are called once at the very beginning of the document and are
-used to construct headers and footers only.
-.
-.Bl -tag -width 6n
-.It Li .Dt Xo
-.Op Aq document title
-.Op Aq section number
-.Op Aq volume
-.Xc
-The document title is the subject of the man page and must be in
-.Tn CAPITALS
-due to troff limitations.
-If omitted,
-.Sq Tn UNTITLED
-is used.
-The section number may be a number in the range
-.No 1,\~ Ns ... Ns ,\~9
-or
-.Ql unass ,
-.Ql draft ,
-or
-.Ql paper .
-If it is specified, and no volume name is given, a default volume name is
-used.
-.
-.Pp
-Under
-.Tn \*[operating-system] ,
-the following sections are defined:
-.Pp
-.TS
-l l l.
-1	\*[volume-operating-system] \*[volume-ds-1]
-2	\*[volume-operating-system] \*[volume-ds-2]
-3	\*[volume-operating-system] \*[volume-ds-3]
-4	\*[volume-operating-system] \*[volume-ds-4]
-5	\*[volume-operating-system] \*[volume-ds-5]
-6	\*[volume-operating-system] \*[volume-ds-6]
-7	\*[volume-operating-system] \*[volume-ds-7]
-8	\*[volume-operating-system] \*[volume-ds-8]
-9	\*[volume-operating-system] \*[volume-ds-9]
-.TE
-.Pp
-.
-A volume name may be arbitrary or one of the following:
-.
-.Pp
-.TS
-l l.
-USD	\*[volume-ds-USD]
-PS1	\*[volume-ds-PS1]
-AMD	\*[volume-ds-AMD]
-SMM	\*[volume-ds-SMM]

-KM 	\*[volume-ds-KM]
-IND	\*[volume-ds-IND]
-LOCAL	\*[volume-ds-LOCAL]
-CON	\*[volume-ds-CON]
-.TE
-.Pp
-.
-For compatibility,
-.Ql MMI
-can be used for
-.Ql IND ,
-and
-.Ql LOC
-for
-.Ql LOCAL .
-Values from the previous table will specify a new volume name.
-If the third parameter is a keyword designating a computer architecture,
-its value is prepended to the default volume name as specified by the
-second parameter.
-By default, the following architecture keywords are defined:
-.

-.Sh "INTRODUCTION OF MANUAL AND GENERAL TEXT DOMAINS"
-.
-.Ss "What's in a Name" Ns ...
-.
-The manual domain macro names are derived from the day to day informal
-language used to describe commands, subroutines and related files.
-Slightly different variations of this language are used to describe the
-three different aspects of writing a man page.
-First, there is the description of
-.Nm \-mdoc
-macro command usage.
-Second is the description of a
-.Ux
-command
-.Em with
-.Nm \-mdoc
-macros, and third, the description of a command to a user in the verbal
-sense; that is, discussion of a command in the text of a man page.
-.Pp
-In the first case,
-.Xr troff 1
-macros are themselves a type of command; the general syntax for a troff
-command is:
-.
-.Bd -filled -offset indent
-.Li ".Xx argument1 argument2" ...
-.Ed
-.Pp
-.
-.Ql .Xx
-is a macro command, and anything following it are arguments to
-be processed.
-In the second case, the description of a
-.Ux
-command using the content macros is a bit more involved; a typical
-.Sx SYNOPSIS
-command line might be displayed as:
-.
-.Bd -filled -offset indent
-.Nm filter
-.Op Fl flag
-.Ao Ar infile Ac Ao Ar outfile Ac
-.Ed
-.Pp
-.
-Here,
-.Nm filter
-is the command name and the
-bracketed string
-.Fl flag
-is a
-.Em flag
-argument designated as optional by the option brackets.
-In
-.Nm \-mdoc
-terms,
-.Ao Ar infile Ac
-and
-.Ao Ar outfile Ac
-are called
-.Em meta arguments ;
-in this example, the user has to replace the meta expressions given in angle
-brackets with real file names.
-Note that in this document meta arguments are used to describe
-.Nm \-mdoc
-commands; in most man pages, meta variables are not specifically written
-with angle brackets.
-The macros which formatted the above example:
-.
-.Bd -literal -offset indent
-\&.Nm filter
-\&.Op Fl flag
-\&.Ao Ar infile Ac Ao Ar outfile Ac
-.Ed
-.Pp
-.
-In the third case, discussion of commands and command syntax includes both
-examples above, but may add more detail.
-The arguments
-.Ao Ar infile Ac
-and
-.Ao Ar outfile Ac
-from the example above might be referred to as
-.Em operands
-or
-.Em file arguments .
-Some command line argument lists are quite long:
-.
-.Bd -ragged
-.Bl -tag -width ".Nm make" -offset indent -compact
-.It Nm make
-.Op Fl eiknqrstv
-.Op Fl D Ar variable
-.Op Fl d Ar flags
-.Op Fl f Ar makefile
-.Op Fl I Ar directory
-.Op Fl j Ar max_jobs
-.Op Ar variable Ns = Ns Ar value
-.Bk
-.Op Ar target ...
-.Ek
-.El
-.Ed
-.Pp
-.
-Here one might talk about the command
-.Nm make
-and qualify the argument,
-.Ar makefile ,
-as an argument to the flag,
-.Fl f ,
-or discuss the optional file operand
-.Ar target .
-In the verbal context, such detail can prevent confusion, however the
-.Nm \-mdoc
-package does not have a macro for an argument
-.Em to
-a flag.
-Instead the
-.Ql \&Ar
-argument macro is used for an operand or file argument like
-.Ar target
-as well as an argument to a flag like
-.Ar variable .
-The make command line was produced from:
-.
-.Bd -literal -offset indent
-\&.Nm make
-\&.Op Fl eiknqrstv
-\&.Op Fl D Ar variable
-\&.Op Fl d Ar flags
-\&.Op Fl f Ar makefile
-\&.Op Fl I Ar directory
-\&.Op Fl j Ar max_jobs
-\&.Op Ar variable Ns = Ns Ar value
-\&.Bk
-\&.Op Ar target ...
-\&.Ek
-.Ed
-.Pp
-.
-The
-.Ql .Bk
-and
-.Ql .Ek
-macros are explained in
-.Sx Keeps .
-.
-.Ss "General Syntax"
-.
-The manual domain and general text domain macros share a similar syntax with
-a few minor deviations; most notably,
-.Ql .Ar ,
-.Ql .Fl ,
-.Ql .Nm ,
-and
-.Ql .Pa
-differ only when called without arguments; and
-.Ql .Fn
-and
-.Ql .Xr
-impose an order on their argument lists.
-All content macros are capable of recognizing and properly handling
-punctuation, provided each punctuation character is separated by a leading
-space.
-If a command is given:
-.Pp
-.Dl \&.Ar sptr, ptr),
-.Pp
-The result is:
-.Pp
-.Dl Ar sptr, ptr),
-.Pp
-The punctuation is not recognized and all is output in the
-font used by
-.Ql .Ar .
-If the punctuation is separated by a leading white space:
-.Pp
-.Dl \&.Ar "sptr , ptr ) ,"
-.Pp
-The result is:
-.Pp
-.Dl Ar sptr , ptr ) ,
-.Pp
-The punctuation is now recognized and output in the default font
-distinguishing it from the argument strings.
-To remove the special meaning from a punctuation character escape it with
-.Ql \e& .
-.Pp
-The following punctuation characters are recognized by
-.Nm \-mdoc :
-.
-.Bl -column -offset indent-two XXXXXX XXXXXX XXXXXX XXXXXX
-.It Li .\& Ta Li ,\& Ta Li :\& Ta Li ;\& Ta Li (\&
-.It Li )\& Ta Li [\& Ta Li ]\& Ta Li ?\& Ta Li !\&
-.El
-.Pp
-.
-.Xr Troff
-is limited as a macro language, and has difficulty when presented with a
-string containing a member of the mathematical, logical or quotation set:
-.
-.Bd -literal -offset indent-two
-{+,\-,/,*,%,<,>,<=,>=,=,==,&,`,',"}
-.Ed
-.Pp
-.
-The problem is that
-.Xr troff
-may assume it is supposed to actually perform the operation or evaluation
-suggested by the characters.
-To prevent the accidental evaluation of these characters, escape them with
-.Ql \e& .
-Typical syntax is shown in the first content macro displayed below,
-.Ql .Ad .

-.Ss "Enclosure and Quoting Macros"
-.
-The concept of enclosure is similar to quoting.
-The object being to enclose one or more strings between a pair of characters
-like quotes or parentheses.
-The terms quoting and enclosure are used interchangeably throughout this
-document.
-Most of the one-line enclosure macros end in small letter
-.Ql q
-to give a hint of quoting, but there are a few irregularities.
-For each enclosure macro there is also a pair of open and close macros which
-end in small letters
-.Ql o
-and
-.Ql c
-respectively.

-have a default width value of 12n.
-.
-.Bl -tag -width ".Li .Ec , .Eo"
-.It Li .Eo , .Ec
-These macros expect the first argument to be the opening and closing strings
-respectively.
-.It Li .Es , .En
-Due to the nine-argument limit in the original troff program two other
-macros have been implemented which are now rather obsolete:
-.Ql .Es
-takes the first and second parameter as the left and right enclosure string,
-which are then used to enclose the arguments of
-.Ql .En .
-The default width value is 12n for both macros.
-.It Li .Eq
-The first and second arguments of this macro are the opening and
-closing strings respectively, followed by the arguments to be enclosed.
-.It Li .Ql
-The quoted literal macro behaves differently in troff and nroff mode.
-If formatted with
-.Xr nroff ,
-a quoted literal is always quoted.
-If formatted with troff, an item is only quoted if the width of the item is
-less than three constant width characters.
-This is to make short strings more visible where the font change to literal
-(constant width) is less noticeable.
-.Pp
-The default width is 16n.

-The prefix macro suppresses the whitespace between its first and second
-argument:

-macro is mandatory.
-If not specified, headers, footers and page layout defaults will not be set
-and things will be rather unpleasant.
-The
-.Em NAME
-section consists of at least three items.
-The first is the
-.Ql .Nm
-name macro naming the subject of the man page.
-The second is the name description macro,
-.Ql .Nd ,
-which separates the subject name from the third item, which is the
-description.
-The description should be the most terse and lucid possible, as the space
-available is small.
-.Pp
-.Ql .Nd
-first prints
-.Ql \- ,
-then all its arguments.
-.
-.It Li ".Sh LIBRARY"
-This section is for section two and three function calls.
-It should consist of a single
-.Ql .Lb
-macro call;
-see
-.Sx "Library Names" .
-.
-.It Li ".Sh SYNOPSIS"
-The
-.Sx SYNOPSIS
-section describes the typical usage of the subject of a man page.
-The macros required are either
-.Ql .Nm ,
-.Ql .Cd ,
-or
-.Ql .Fn
-(and possibly
-.Ql .Fo ,
-.Ql .Fc ,
-.Ql .Fd ,
-and
-.Ql .Ft ) .
-The function name macro
-.Ql .Fn
-is required for manual page sections\~2 and\~3; the command and general name
-macro
-.Ql .Nm
-is required for sections 1, 5, 6, 7, and\~8.
-Section\~4 manuals require a
-.Ql .Nm ,
-.Ql .Fd
-or a
-.Ql .Cd
-configuration device usage macro.
-Several other macros may be necessary to produce the synopsis line as shown
-below:
-.
-.Bd -filled -offset indent
-.Nm cat
-.Op Fl benstuv
-.Op Fl
-.Ar

-.Dl ".Op Fl"
-.Dl .Ar
-.
-.It Li ".Sh DESCRIPTION"
-In most cases the first text in the
-.Sx DESCRIPTION
-section is a brief paragraph on the command, function or file, followed by a
-lexical list of options and respective explanations.
-To create such a list, the
-.Ql .Bl
-(begin list),
-.Ql .It
-(list item) and
-.Ql .El
-(end list)
-macros are used (see
-.Sx Lists and Columns
-below).
-.
-.It Li ".Sh IMPLEMENTATION NOTES"
-Implementation specific information should be placed here.
-.
-.It Li ".Sh RETURN VALUES"
-Sections 2, 3 and\~9 function return values should go here.
-The
-.Ql .Rv
-macro may be used to generate text for use in the
-.Sx RETURN VALUES
-section for most section 2 and 3 library functions;
-see
-.Sx "Return Values" .
-.El
-.Pp
-.
-The following
-.Ql .Sh
-section headers are part of the preferred manual page layout and must be
-used appropriately to maintain consistency.
-They are listed in the order in which they would be used.
-.
-.Bl -tag -width ".Li .Sh\ COMPATIBILITY"
-.It Li ".Sh ENVIRONMENT"
-The
-.Em ENVIRONMENT
-section should reveal any related environment variables and clues to their
-behavior and/or usage.
-.
-.It Li ".Sh FILES"
-Files which are used or created by the man page subject should be listed via
-the
-.Ql .Pa
-macro in the
-.Sx FILES
-section.
-.
-.It Li ".Sh EXAMPLES"
-There are several ways to create examples.
-See the
-.Em EXAMPLES
-section below for details.
-.
-.It Li ".Sh DIAGNOSTICS"
-Diagnostic messages from a command should be placed in this section.
-The
-.Ql .Ex
-macro may be used to generate text for use in the
-.Sx DIAGNOSTICS
-section for most section 1, 6 and\~8 commands;
-see
-.Sx "Exit Status" .
-.
-.It Li ".Sh COMPATIBILITY"
-Known compatibility issues (e.g. deprecated options or parameters)
-should be listed here.
-.
-.It Li ".Sh ERRORS"
-Specific error handling, especially from library functions (man page
-sections 2, 3, and\~9) should go here.
-The
-.Ql .Er
-macro is used to specify an error (errno).
-.
-.It Li ".Sh SEE ALSO"
-References to other material on the man page topic and cross references to
-other relevant man pages should be placed in the
-.Sx "SEE ALSO"
-section.
-Cross references are specified using the
-.Ql .Xr
-macro.
-Currently
-.Xr refer 1
-style references are not accommodated.
-.Pp
-It is recommended that the cross references are sorted on the section
-number, then alphabetically on the names within a section, and placed
-in that order and comma separated.
-Example:
-.Pp
-.Xr ls 1 ,
-.Xr ps 1 ,
-.Xr group 5 ,
-.Xr passwd 5
-.
-.It Li ".Sh STANDARDS"
-If the command, library function or file adheres to a specific
-implementation such as
-.St -p1003.2
-or
-.St -ansiC
-this should be noted here.
-If the command does not adhere to any standard, its history should be noted
-in the
-.Em HISTORY
-section.
-.
-.It Li ".Sh HISTORY"
-Any command which does not adhere to any specific standards should be
-outlined historically in this section.
-.
-.It Li ".Sh AUTHORS"
-Credits should be placed here.
-Use the
-.Ql .An
-macro for names and the
-.Ql .Aq
-macro for e-mail addresses within optional contact information.
-Explicitly indicate whether the person authored the initial manual page
-or the software or whatever the person is being credited for.
-.It Li ".Sh BUGS"
-Blatant problems with the topic go here.

-.Ss "Subsection Headers"
-.
-Subsection headers have exactly the same syntax as section headers:
-.Ql .Ss
-is parsed but not generally callable.
-It can be used as an argument in a call to
-.Ql .Ss
-only; it then reactivates the default font for
-.Ql .Ss .
-.Pp
-The default width is 8n.
-.
-.Ss "Paragraphs and Line Spacing"
-.
-.Bl -tag -width ".Li .Pp"
-.It Li .Pp
-The 
-.Ql .Pp
-paragraph command may be used to specify a line space where necessary.
-The macro is not necessary after a
-.Ql .Sh
-or
-.Ql .Ss
-macro or before a
-.Ql .Bl
-or
-.Ql .Bd
-macro (which both assert a vertical distance unless the
-.Fl compact
-flag is given).

-.Ss Keeps
-.
-The only keep that is implemented at this time is for words.
-The macros are
-.Ql .Bk
-(begin keep)
-and
-.Ql .Ek
-(end keep).
-The only option that
-.Ql .Bk
-accepts currently is
-.Fl words
-(this is also the default if no option is given) which is useful for
-preventing line breaks in the middle of options.
-In the example for the make command line arguments (see
-.Sx What's in a Name ) ,
-the keep prevented
-.Xr nroff
-from placing up the flag and the argument on separate lines.
-.Pp
-Both macros are neither callable nor parsed.
-.Pp
-More work needs to be done with the keep macros; specifically, a
-.Fl line
-option should be added.
-.
-.Ss "Examples and Displays"
-.
-There are seven types of displays.
-.Pp
-.Bl -tag -width ".Li .D1"
-.It Li .D1
-(This is D-one.)
-Display one line of indented text.
-This macro is parsed but not callable.
-.Pp
-.D1 Fl ldghfstru
-.Pp
-The above was produced by:
-.Li ".D1 Fl ldghfstru" .
-.
-.It Li .Dl
-(This is D-ell.)
-Display one line of indented
-.Em literal
-text.
-The
-.Ql .Dl
-example macro has been used throughout this file.
-It allows the indentation (display) of one line of text.
-Its default font is set to constant width (literal).
-.Ql .Dl
-is parsed but not callable.
-.Pp
-.Dl % ls \-ldg /usr/local/bin
-.Pp
-The above was produced by:
-.Li ".Dl % ls \e\-ldg /usr/local/bin" .
-.
-.It Li .Bd
-Begin display.
-The
-.Ql .Bd
-display must be ended with the
-.Ql .Ed
-macro.
-It has the following syntax:
-.Pp
-.Bd -ragged -compact
-.Bl -tag -width ".Li .Bd" -offset indent
-.It Li .Bd Xo
-.Bro \-literal | \-filled | \-unfilled | \-ragged | \-centered Brc

-.El
-.Ed
-.Pp
-.
-.Bl -tag -width ".Fl file Ao Ar file name Ac " -compact
-.It Fl ragged
-Fill, but do not adjust the right margin (only left-justify).
-.It Fl centered
-Center lines between the current left and right margin.
-Note that each single line is centered.
-.It Fl unfilled
-Do not fill; display a block of text as typed, using line breaks as
-specified by the user.
-This can produce overlong lines without warning messages.
-.It Fl filled
-Display a filled block.
-The block of text is formatted (i.e., the text is justified on both the left
-and right side).
-.It Fl literal
-Display block with literal font (usually fixed-width).
-Useful for source code or simple tabbed or spaced text.
-.It Fl file Ao Ar file name Ac
-The file whose name follows the
-.Fl file
-flag is read and displayed before any data enclosed with
-.Ql .Bd
-and
-.Ql .Ed ,
-using the selected display type.
-Any
-.Xr troff/ Ns Nm \-mdoc
-commands in the file will be processed.
-.It Fl offset Ao Ar string Ac
-If
-.Fl offset
-is specified with one of the following strings, the string is interpreted to
-indicate the level of indentation for the forthcoming block of text:
-.
-.Pp
-.Bl -tag -width ".Ar indent-two" -compact
-.It Ar left
-Align block on the current left margin; this is the default mode of
-.Ql .Bd .
-.It Ar center
-Supposedly center the block.
-At this time unfortunately, the block merely gets left aligned about an
-imaginary center margin.
-.It Ar indent
-Indent by one default indent value or tab.
-The default indent value is also used for the
-.Ql .D1
-and 
-.Ql .Dl
-macros, so one is guaranteed the two types of displays will line up.
-The indentation value is normally set to\~6n or about two thirds of an inch
-(six constant width characters).
-.It Ar indent\-two
-Indent two times the default indent value.
-.It Ar right
-This
-.Em left
-aligns the block about two inches from the right side of the page.
-This macro needs work and perhaps may never do the right thing within
-.Xr troff .
-.El
-.Pp
-.
-If
-.Ao string Ac
-is a valid numeric expression instead
-.Pf ( Em with a scale indicator other than
-.Sq Em u ) ,
-use that value for indentation.
-The most useful scale indicators are
-.Sq m
-and
-.Sq n ,
-specifying the so-called
-.Em \&Em
-and
-.Em "En square" .
-This is approximately the width of the letters
-.Sq m
-and
-.Sq n
-respectively
-of the current font (for nroff output, both scale indicators give the same
-values).
-If
-.Ao string Ac
-isn't a numeric expression, it is tested whether it is an
-.Nm \-mdoc
-macro name, and the default offset value associated with this macro is used.
-Finally, if all tests fail,
-the width of
-.Ao string Ac
-(typeset with a fixed-width font) is taken as the offset.
-.It Fl compact
-Suppress insertion of vertical space before begin of display.
-.El
-.
-.It Li .Ed
-End display (takes no arguments).
-.El
-.
-.Ss "Lists and Columns"
-.
-There are several types of lists which may be initiated with the
-.Ql .Bl
-begin-list macro.
-Items within the list are specified with the
-.Ql .It
-item macro, and each list must end with the
-.Ql .El
-macro.
-Lists may be nested within themselves and within displays.
-The use of columns inside of lists or lists inside of columns is unproven.
-.Pp
-In addition, several list attributes may be specified such as the width of a
-tag, the list offset, and compactness (blank lines between items allowed or
-disallowed).
-Most of this document has been formatted with a tag style list
-.Pf ( Fl tag ) .
-.Pp
-It has the following syntax forms:
-.
-.Pp
-.Bd -ragged -compact
-.Bl -tag -width ".Li .Bl" -offset indent -compact
-.It Li .Bl Xo

-This list type generates multiple columns.
-The number of columns and the width of each column is determined by the

-If

-(Note that the current state of
-.Nm \-mdoc
-is saved before
-.Aq Ar string
-is interpreted; afterwards, all variables are restored again.
-However, boxes (used for enclosures) can't be saved in
-.Tn GNU
-.Xr troff 1 ;
-as a consequence, arguments must always be
-.Em balanced
-to avoid nasty errors.
-For example, do not write
-.Ql ".Ao Ar string"
-but
-.Ql ".Ao Ar string Xc"
-instead if you really need only an opening angle bracket.)
-.Pp
-Otherwise, if
-.Aq Ar string
-is a valid numeric expression
-.Em ( with a scale indicator other than
-.Sq Em u ) ,
-use that value for indentation.
-The most useful scale indicators are
-.Sq m
-and
-.Sq n ,
-specifying the so-called
-.Em \&Em
-and
-.Em "En square" .
-This is approximately the width of the letters
-.Sq m
-and
-.Sq n
-respectively
-of the current font (for nroff output, both scale indicators give the same
-values).
-If
-.Aq Ar string
-isn't a numeric expression, it is tested whether it is an
-.Nm \-mdoc
-macro name, and the default width value associated with this macro is used.
-Finally, if all tests fail,
-the width of
-.Aq Ar string
-(typeset with a fixed-width font) is taken as the width.
-.Pp
-If a width is not specified for the tag list type, every time
-.Ql .It
-is invoked, an attempt is made to determine an appropriate width.
-If the first argument to
-.Ql .It
-is a callable macro, the default width for that macro will be used;
-otherwise, the default width of
-.Ql .No
-is used.
-.It Fl offset Ao Ar string Ac
-If
-.Aq Ar string
-is
-.Ar indent ,
-a default indent value (normally set to\~6n, similar to the value used in
-.Ql .Dl
-or
-.Ql .Bd )
-is used.
-If
-.Aq Ar string
-is a valid numeric expression instead
-.Pf ( Em with a scale indicator other than
-.Sq Em u ) ,
-use that value for indentation.
-The most useful scale indicators are
-.Sq m
-and
-.Sq n ,
-specifying the so-called
-.Em \&Em
-and
-.Em "En square" .
-This is approximately the width of the letters
-.Sq m

-If
-.Aq Ar string
-isn't a numeric expression, it is tested whether it is an

-.It Li .Fr
-.Pp
-.Dl Usage: .Fr Ao function return value Ac ...
-.Pp
-Don't use this macro.
-It allows a break right before the return value (usually a single digit)
-which is bad typographical behaviour.
-Use

-.Pp
-The names of the columns
-.Sy Nroff
-and
-.Sy Troff
-are a bit misleading;
-.Sy Nroff
-shows the
-.Tn ASCII
-representation, while
-.Sy Troff
-gives the best glyph form available.
-For example, a Unicode enabled
-.Tn TTY Ns - Ns
-device will have proper glyph representations for all strings, whereas the
-enhancement for a Latin1
-.Tn TTY Ns - Ns
-device is only the plus-minus sign.
-.Pp
-String names which consist of two characters can be written as
-.Ql \e*(xx ;
-string names which consist of one character can be written as
-.Ql \e*x .
-A generic syntax for a string name of any length is
-.Ql \e*[xxx]
-(this is a
-.Tn GNU
-.Xr troff 1
-extension).

-.Sh DIAGNOSTICS
-.
-The debugging macro
-.Ql .Db
-available in previous versions of
-.Nm \-mdoc
-has been removed since
-.Tn GNU
-.Xr troff 1
-provides better facilities to check parameters; additionally, many error and
-warning messages have been added to this macro package, making it both more
-robust and verbose.
-.Pp
-The only remaining debugging macro is
-.Ql .Rd
-which yields a register dump of all global registers and strings.
-A normal user will never need it.
-.
-.
-.Sh "FORMATTING WITH GROFF, TROFF, AND NROFF"
-.
-By default, the package inhibits page breaks, headers, and footers if
-displayed with a
-.Tn TTY
-device like
-.Sq latin1
-or
-.Sq unicode ,
-to make the manual more efficient for viewing on-line.
-This behaviour can be changed (e.g.\& to create a hardcopy of the
-.Tn TTY
-output) by setting the register
-.Ql cR
-to zero while calling
-.Xr groff 1 ,
-resulting in multiple pages instead of a single, very long page:
-.Pp
-.Dl groff \-Tlatin1 \-rcR=0 \-mdoc foo.man > foo.txt
-.Pp
-For double-sided printing, set register
-.Ql D
-to\~1:
-.Pp
-.Dl groff \-Tps \-rD1 \-mdoc foo.man > foo.ps
-.Pp
-To change the document font size to 11pt or 12pt, set register
-.Ql S
-accordingly:
-.Pp
-.Dl groff \-Tdvi \-rS11 \-mdoc foo.man > foo.dvi
-.Pp
-Register
-.Ql S
-is ignored for
-.Tn TTY
-devices.
-.Pp
-The line and title length can be changed by setting the registers
-.Ql LL
-and
-.Ql LT ,
-respectively:
-.Pp
-.Dl groff \-Tutf8 \-rLL=100n \-rLT=100n \-mdoc foo.man | less
-.Pp
-If not set, both registers default to 78n for TTY devices and 6.5i
-otherwise.

-.SH DESCRIPTION
-.
-This manual page describes the GNU version of the
-.I ms
-macros,
-part of the
-.I groff
-typesetting system.
-The
-.I ms
-macros are mostly compatible with the
-documented behavior of the 4.3
-.SM BSD
-Unix
-.I ms
-macros (see
-.I Differences from troff ms
-below for details).
-The
-.I ms
-macros are suitable for reports, letters, books, and
-technical documentation.
-.
-.
-.
-.SH USAGE
-.
-The
-.I ms
-macro package expects files to have
-a certain amount of structure.
-The simplest documents can begin with a paragraph macro
-and consist of text separated by paragraph macros
-or even blank lines.
-Longer documents have a structure as follows:
-.
-.TP
-.B "Document type"
-If you use the
-.B RP
-(report) macro at the beginning of the document,
-.I groff
-prints the cover page information on its own page;
-otherwise it prints the information on the
-first page with your document text immediately following.
-Other document formats found in AT&T
-.I troff
-are specific to AT&T
-or Berkeley, and are not supported in
-.IR "groff ms" .
-.
-.TP
-.B "Format and layout"
-By setting number registers,
-you can change your document's type (font and size),
-margins, spacing, headers and footers, and footnotes.
-See 
-.I "Document control registers"
-below for more details.
-.
-.TP
-.B "Cover page"
-A cover page consists of a title,
-and optionally the author's name and institution,
-an abstract, and the date.
-See
-.I "Cover page macros"
-below for more details.
-.
-.TP
-.B "Body"
-Following the cover page is your document.
-It consists of paragraphs, headings, and lists.
-.
-.TP
-.B "Table of contents"
-Longer documents usually include a table of contents,
-which you can add by placing the
-.B TC
-macro at the end of your document.
-.
-.
-.SS "Document control registers"
-.
-The following table lists the document control
-number registers.
-For the sake of consistency,
-set registers related to margins at the beginning of your document,
-or just after the
-.B RP
-macro.

-.SS "Cover page macros"
-.
-Use the following macros to create a cover page for your document
-in the order shown.
-.
-.TP
-.B .RP [no]
-Specifies the report format for your document.
-The report format creates a separate cover page.
-With no
-.B RP
-macro,
-.I groff
-prints a subset of the
-cover page on page\~1 of your document.
-.
-.IP
-If you use the optional
-.B no
-argument,
-.I groff
-prints a title page but
-does not repeat any of the title page information
-(title, author, abstract, etc.\&)
-on page\~1 of the document.
-.
-.TP
-.B .P1 
-(P-one) Prints the header on page\~1.
-The default is to suppress the header.
-.
-.TP
-.BI ".DA [" xxx ]
-(optional) Print the current date,
-or the arguments to the macro if any,
-on the title page (if specified)
-and in the footers.
-This is the default for
-.IR nroff .
-.
-.TP
-.BI ".ND [" xxx ]
-(optional) Print the current date,
-or the arguments to the macro if any,
-on the title page (if specified)
-but not in the footers.
-This is the default for
-.IR troff .
-.
-.TP
-.B .TL
-Specifies the document title.
-.I Groff
-collects text following the
-.B TL
-macro into the title, until reaching the author name or abstract.
-.
-.TP
-.B .AU
-Specifies the author's name.
-You can specify multiple authors by using an
-.B AU
-macro for each author.
-.
-.TP
-.B .AI
-Specifies the author's institution.
-You can specify multiple institutions.
-.
-.TP
-.B .AB [no]
-Begins the abstract.
-The default is to print the word
-.BR ABSTRACT ,
-centered and in italics, above the text of the abstract.
-The option
-.B no
-suppresses this heading.
-.
-.TP
-.B .AE
-End the abstract.
-.
-.
-.SS Paragraphs
-.
-Use the
-.B PP
-macro to create indented paragraphs,
-and the
-.B LP
-macro to create paragraphs with no initial indent.
-.
-.PP
-The
-.B QP
-macro indents all text at both left and right margins.
-The effect is identical to the HTML
-.B <BLOCKQUOTE>
-element.
-The next paragraph or heading
-returns margins to normal.
-.
-.PP
-The
-.B XP
-macro produces an exdented paragraph.
-The first line of the paragraph begins at
-the left margin,
-and subsequent lines are indented
-(the opposite of
-.BR PP ).
-.
-.PP
-For each of the above paragraph types,
-and also for any list entry introduced by the
-.B IP
-macro
-(described later),
-the document control register
-.BR PORPHANS ,
-sets the
-.I minimum
-number of lines which must be printed,
-after the start of the paragraph,
-and before any page break occurs.
-If there is insufficient space remaining on the current page
-to accommodate this number of lines,
-then a page break is forced
-.I before
-the first line of the paragraph is printed.
-.
-.PP
-Similarly,
-when a section heading
-(see subsection
-.I Headings
-below)
-preceeds any of these paragraph types,
-the
-.B HORPHANS
-document control register specifies the
-.I minimum
-number of lines of the paragraph
-which must be kept on the same page as the heading.
-If insufficient space remains on the current page
-to accommodate the heading and this number of lines of paragraph text,
-then a page break is forced
-.I before
-the heading is printed.
-.
-.
-.SS Headings
-.
-Use headings to create a hierarchical structure
-for your document.
-By default,
-the
-.I ms
-macros print headings in
-.B bold
-using the same font family and point size as the body text.
-For output devices which support scalable fonts,
-this behaviour may be modified,
-by defining the document control registers,
-.B GROWPS
-and
-.BR PSINCR .
-.
-.PP
-The following heading macros are available:
-.
-.TP
-.BI .NH\  xx
-Numbered heading.
-The argument
-.I xx
-is either a numeric argument to indicate the
-level of the heading, or
-.I S\ xx\ xx\ \c
-".\|.\|."
-to set the section number explicitly.
-If you specify heading levels out of sequence,
-such as invoking
-.B ".NH\ 3"
-after
-.BR ".NH\ 1" ,
-.I groff
-prints a warning on standard error.
-.
-.IP
-If the
-.B GROWPS
-register is set to a value
-greater than the level of the heading,
-then the point size of the heading will be increased by
-.B PSINCR
-units over the text size specified by the
-.B PS
-register,
-for each level by which the heading level is less than
-the value of
-.BR GROWPS .
-For example,
-the sequence:
-.
-.RS
-.ne 12
-.nf
-.IP
-\&.nr PS 10
-\&.nr GROWPS 3
-\&.nr PSINCR 1.5p
-\&.
-\&.NH 1
-Top Level Heading
-\&.
-\&.NH 2
-Second Level Heading
-\&.
-\&.NH 3
-Third Level Heading
-.fi
-.RE
-.
-.IP
-will cause
-.RI \*(lq 1.\ Top\ Level\ Heading \*(rq
-to be printed in 13pt
-.B bold
-text, followed by
-.RI \*(lq 1.1.\ Second\ Level\ Heading \*(rq
-in 11.5pt
-.B bold
-text, while
-.RI \*(lq 1.1.1.\ Third\ Level\ Heading \*(rq,
-and all more deeply nested heading levels,
-will remain in the 10pt
-.B bold
-text which is specified by the
-.B PS
-register.
-.
-.IP
-Note that the value stored in
-.B PSINCR
-is interpreted in
-.I groff
-basic units;
-the
-.I p
-scaling factor should be employed,
-when assigning a value specified in points.
-.
-.IP
-After invoking
-.BR .NH ,
-the assigned heading number is available in the strings
-.B SN-DOT
-(exactly as it appears in the formatted heading),
-and
-.B SN-NO-DOT
-(with its final period omitted).
-The string
-.B SN
-is also defined,
-as an alias for
-.BR SN-DOT ;
-if preferred,
-the user may redefine it as an alias for
-.BR SN-NO-DOT ,
-'ne 10
-by including the initialisation:
-.
-.RS
-.nf
-.IP
-\&.ds SN-NO-DOT
-\&.als SN SN-NO-DOT
-.fi
-.RE
-.
-.IP
-.I before
-the first use of
-.BR .NH ,
-or simply:
-.
-.RS
-.nf
-.IP
-\&.als SN SN-NO-DOT
-.fi
-.RE
-.
-.IP
-.I after
-the first use of
-.BR .NH .
-.
-.TP
-.BI .SH\ [ xx ]
-Unnumbered subheading.
-The use of the optional
-.I xx
-argument is a GNU extension,
-which adjusts the point size of the unnumbered subheading
-to match that of a numbered heading,
-introduced using
-.BI .NH\  xx
-with the same value of
-.IR xx .
-For example,
-given the same settings for
-.BR PS ,
-.B GROWPS
-and
-.BR PSINCR ,
-as used in the preceeding
-.B .NH
-example,
-the sequence:
-.
-.RS
-.ne
-.nf
-.IP
-\&.SH 2
-An Unnumbered Subheading
-.fi
-.RE
-.
-.IP
-will print
-.RI \*(lq "An Unnumbered Subheading" \*(rq
-in 11.5pt
-.B bold
-text.
-.
-.
-.SS Highlighting
-.
-The
-.I ms
-macros provide a variety of methods to highlight
-or emphasize text:
-.
-.TP
-.B ".B [\fItxt\fP [\fIpost\fP [\fIpre\fP]]]"
-Sets its first argument in
-.BR "bold type" .
-If you specify a second argument,
-.I groff
-prints it in the previous font after
-the bold text, with no intervening space
-(this allows you to set punctuation after
-the highlighted text without highlighting
-the punctuation).
-Similarly, it prints the third argument (if any)
-in the previous font
-.B before
-the first argument.
-For example,
-.RS
-.
-.IP
-\&.B foo ) (
-.RE
-.
-.IP
-prints
-.RB ( foo ).
-.
-.IP
-If you give this macro no arguments,
-.I groff
-prints all text following in bold until
-the next highlighting, paragraph, or heading macro.
-.
-.TP
-.B ".R [\fItxt\fP [\fIpost\fP [\fIpre\fP]]]"
-Sets its first argument in
-roman (or regular) type.
-It operates similarly to the
-.B B
-macro otherwise.
-.
-.TP
-.B ".I [\fItxt\fP [\fIpost\fP [\fIpre\fP]]]"
-Sets its first argument in
-.IR "italic type" .
-It operates similarly to the
-.B B
-macro otherwise.
-.
-.TP
-.B ".CW [\fItxt\fP [\fIpost\fP [\fIpre\fP]]]"
-Sets its first argument in a constant width face.
-It operates similarly to the
-.B B
-macro otherwise.
-.
-.TP
-.B ".BI [\fItxt\fP [\fIpost\fP [\fIpre\fP]]]"
-Sets its first argument in bold italic type.
-It operates similarly to the
-.B B
-macro otherwise.
-.
-.TP
-.BI ".BX [" txt ]
-Prints its argument and draws a box around it.
-If you want to box a string that contains spaces,
-use a digit-width space (\[rs]0).
-.
-.TP
-.BI ".UL [" txt " [" post ]]
-Prints its first argument with an underline.
-If you specify a second argument,
-.I groff
-prints it in the previous font after
-the underlined text, with no intervening space.
-.
-.TP
-.B .LG
-Prints all text following in larger type
-(2\~points larger than the current point size) until
-the next font size, highlighting, paragraph, or heading macro.
-You can specify this macro multiple times
-to enlarge the point size as needed.
-.
-.TP
-.B .SM
-Prints all text following in
-smaller type
-(2\~points smaller than the current point size) until
-the next type size, highlighting, paragraph, or heading macro.
-You can specify this macro multiple times
-to reduce the point size as needed.
-.
-.TP
-.B .NL
-Prints all text following in
-the normal point size
-(that is, the value of the
-.B PS
-register).
-.
-.TP
-.BI \[rs]*{ text \[rs]*}
-Print the enclosed
-.I text
-as a superscript.
-.
-.
-.SS Indents
-.
-You may need to indent sections of text.
-A typical use for indents is to create nested lists and sublists.
-.
-.PP
-Use the
-.B RS
-and
-.B RE
-macros to start and end a section of indented text, respectively.
-The
-.B PI
-register controls the amount of indent.
-.
-.PP
-You can nest indented sections as deeply as needed by
-using multiple, nested pairs of
-.B RS
-and
-.BR RE .
-.
-.
-.SS Lists
-.
-The
-.B IP
-macro handles duties for all lists.
-Its syntax is as follows:
-.
-.TP
-.BI ".IP [" marker " [" width ]]
-.
-.IP
-The
-.I marker
-is usually a bullet character
-.B \[rs](bu
-for unordered lists,
-a number (or auto-incrementing number register) for numbered lists,
-or a word or phrase for indented (glossary-style) lists.
-.
-.IP
-The
-.I width
-specifies the indent for the body of each list item.
-Once specified, the indent remains the same for all
-list items in the document until specified again.
-.\" -----
-.br
-.ne 15
-.
-.
-.SS "Tab stops"
-.
-Use the
-.B ta
-request to set tab stops as needed.
-Use the
-.B TA
-macro to reset tabs to the default (every 5n).
-You can redefine the
-.B TA
-macro to create a different set of default tab stops.
-.
-.
-.SS "Displays and keeps"
-.
-Use displays to show text-based examples or figures
-(such as code listings).
-Displays turn off filling, so lines of code can be
-displayed as-is without inserting
-.B br
-requests in between each line.
-Displays can be 
-.I kept
-on a single page, or allowed to break across pages.
-The following table shows the display types available.

-.
-.LP
-Use the
-.B DE
-macro to end any display type.
-The macros
-.B Ds
-and
-.B De
-were formerly provided as aliases for
-.B DS
-and
-.BR DE ,
-respectively, but they have been removed, and should no longer be used.
-X11 documents which actually use
-.B Ds
-and
-.B De
-always load a specific macro file from the X11 distribution (macros.t)
-which provides proper definitions for the two macros.
-.PP
-To
-.I keep
-text together on a page,
-such as
-a paragraph that refers to a table (or list, or other item)
-immediately following, use the
-.B KS
-and
-.B KE
-macros.
-The
-.B KS
-macro begins a block of text to be kept on a single page,
-and the
-.B KE
-macro ends the block.
-.
-.PP
-You can specify a
-.I "floating keep"
-using the
-.B KF
-and
-.B KE
-macros.
-If the keep cannot fit on the current page,
-.I groff
-holds the contents of the keep and allows text following
-the keep (in the source file) to fill in the remainder of
-the current page.
-When the page breaks,
-whether by an explicit
-.B bp
-request or by reaching the end of the page,
-.I groff
-prints the floating keep at the top of the new page.
-This is useful for printing large graphics or tables
-that do not need to appear exactly where specified.
-.
-.PP
-The macros
-.B B1
-and
-.B B2
-can be used to enclose a text within a box;
-.B .B1
-begins the box, and
-.B .B2
-ends it.
-Text in the box is automatically placed in a diversion
-(keep).
-.
-.
-.SS "Tables, figures, equations, and references"
-.
-The
-.I -ms
-macros support the standard
-.I groff
-preprocessors:
-.IR tbl ,
-.IR pic ,
-.IR eqn ,
-and
-.IR refer .
-Mark text meant for preprocessors by enclosing it
-in pairs of tags as follows:
-.
-.TP
-.BR ".TS [H]" " and " .TE
-Denotes a table, to be processed by the
-.I tbl
-preprocessor.
-The optional
-.BR H "\~argument"
-instructs
-.I groff
-to create a running header with the information
-up to the
-.B TH
-macro.
-.I Groff
-prints the header at the beginning of the table;
-if the table runs onto another page,
-.I groff
-prints the header on the next page as well.
-.
-.TP
-.BR .PS " and " .PE
-Denotes a graphic, to be processed by the
-.I pic
-preprocessor.
-You can create a
-.I pic
-file by hand, using the
-AT&T
-.I pic
-manual available on the Web as a reference,
-or by using a graphics program such as
-.IR xfig .
-.
-.TP
-.BR ".EQ [\fI\,align\/\fP]" " and " .EN
-Denotes an equation, to be processed by the
-.I eqn
-preprocessor.
-The optional
-.I align
-argument can be
-.BR C ,
-.BR L ,
-or\~\c
-.B I
-to center (the default), left-justify, or indent

-.
-.SS Footnotes
-.
-The
-.I ms
-macros provide a flexible footnote system.
-You can specify a numbered footnote by using the
-.B \[rs]**
-escape, followed by the text of the footnote
-enclosed by
-.B FS
-and
-.B FE
-macros.
-.
-.PP
-You can specify symbolic footnotes
-by placing the mark character (such as
-.B \[rs](dg
-for the dagger character) in the body text,
-followed by the text of the footnote
-enclosed by
-.B FS\ \[rs](dg
-and
-.B FE
-macros.
-.
-.PP
-You can control how
-.I groff
-prints footnote numbers by changing the value of the
-.B FF
-register as follows:
-.RS
-.ne 7
-.
-.TP
-0
-Prints the footnote number as a superscript; indents the footnote (default).
-.
-.TP
-1
-Prints the number followed by a period (like\~1.\&)
-and indents the footnote.
-.
-.TP
-2
-Like\~1, without an indent.
-.
-.TP
-3
-Like\~1, but prints the footnote number as a hanging paragraph.
-.
-.LP
-.RE
-You can use footnotes safely within keeps and displays,
-but avoid using numbered footnotes within floating keeps.
-You can set a second
-.B \[rs]**
-between a
-.B \[rs]**
-and its corresponding
-.BR .FS ;
-as long as each
-.B .FS
-occurs
-.I after
-the corresponding
-.B \[rs]**
-and the occurrences of
-.B .FS
-are in the same order as the corresponding occurrences of
-.BR \[rs]** .
-.
-.
-.SS "Headers and footers"
-.
-There are two ways to define headers and footers:
-.
-.IP \(bu 3n
-Use the strings
-.BR LH ,
-.BR CH ,
-and
-.B RH
-to set the left, center, and right headers; use
-.BR LF ,
-.BR CF ,
-and
-.B RF
-to set the left, center, and right footers.
-This works best for documents that do not distinguish
-between odd and even pages.
-.
-.IP \(bu
-Use the
-.B OH
-and
-.B EH
-macros to define headers for the odd and even pages; and
-.B OF
-and
-.B EF
-macros to define footers for the odd and even pages.
-This is more flexible than defining the individual strings.
-The syntax for these macros is as follows:
-.RS
-.
-.IP
-.B ".OH '\fIleft\fP'\fIcenter\fP'\fIright\fP'"
-.RE
-.
-.IP
-You can replace the quote (') marks with any character not
-appearing in the header or footer text.
-.
-.
-.SS Margins
-.
-You control margins using a set of number registers.
-The following table lists the register names and defaults:
-.RS
-.ne 8
-.na
-.TS
-cb   s cb s s cb s cb s
-afCW s l  s s l  s l  s.
-Reg.	Definition	Effective	Default
-_
-PO	T{
-Page offset (left margin)
-T}	next page	1i
-LL	T{
-Line length
-T}	next para.	6i
-LT	T{
-Header/footer length
-T}	next para.	6i
-HM	T{
-Top (header) margin
-T}	next page	1i
-FM	T{
-Bottom (footer) margin
-T}	next page	1i
-_
-.TE
-.RE
-.ad
-.
-.PP
-Note that there is no right margin setting.
-The combination of page offset and line length
-provide the information necessary to
-derive the right margin.
-.
-.
-.SS "Multiple columns"
-.
-The
-.I ms
-macros can set text in as many columns as will reasonably
-fit on the page.
-The following macros are available.
-All of them force a page break if a multi-column mode is already set.
-However, if the current mode is single-column, starting a multi-column
-mode does
-.I not
-force a page break.
-.
-.TP
-.B .1C
-Single-column mode.
-.
-.TP
-.B .2C
-Two-column mode.
-.
-.TP
-.BI ".MC [" width " [" gutter ]]
-Multi-column mode.
-If you specify no arguments, it is equivalent to the
-.B 2C
-macro.
-Otherwise,
-.I width
-is the width of each column and
-.I gutter
-is the space between columns.
-The
-.B MINGW
-number register is the default gutter width.
-.
-.
-.SS "Creating a table of contents"
-.
-Wrap text that you want to appear in the
-table of contents in
-.B XS
-and
-.B XE
-macros.
-Use the
-.B TC
-macro to print the table of contents at the end of the document,
-resetting the page number to\~\c
-.B i
-(Roman numeral\~1).
-.
-.PP
-You can manually create a table of contents
-by specifying a page number as the first argument to
-.BR XS .
-Add subsequent entries using the
-.B XA
-macro.
-For example:
-.RS
-.
-.PP
-.ne 8
-.nf
-\&.XS 1
-Introduction
-\&.XA 2
-A Brief History of the Universe
-\&.XA 729
-Details of Galactic Formation
-\&.\|.\|.
-\&.XE
-.fi
-.RE  
-.
-.LP  
-Use the
-.B PX  
-macro to print a manually-generated table of contents
-without resetting the page number.
-.
-.PP
-If you give the argument
-.B no
-to either
-.B PX
-or   
-.BR TC ,
-.I groff
-suppresses printing the title
-specified by the
-.B \[rs]*[TOC]  
-string.
-.
-.
-.SS "Fractional point sizes"
-.
-Traditionally, the
-.I ms
-macros only support integer values for the document's font size and
-vertical spacing.
-To overcome this restriction, values larger than or equal to 1000 are taken
-as fractional values, multiplied by 1000.
-For example, `.nr\~PS\~10250' sets the font size to 10.25 points.
-.
-.LP
-The following four registers accept fractional point sizes:
-.BR PS ,
-.BR VS ,
-.BR FPS ,
-and
-.BR FVS .
-.
-.LP
-Due to backwards compatibility, the value of
-.B VS
-must be smaller than 40000 (this is 40.0 points).
-.
-.
-.
-.SH "DIFFERENCES FROM troff ms"
-.
-The
-.I "groff ms"
-macros are a complete re-implementation,
-using no original AT&T code.
-Since they take advantage of the extended features in
-.IR groff ,
-they cannot be used with AT&T
-.IR troff .
-Other differences include:
-.
-.IP \(bu 3n
-The internals of
-.I "groff ms"
-differ from the internals of Unix
-.IR ms . 
-Documents that depend upon implementation details of Unix
-.I ms
-may not format properly with
-.IR "groff ms" .
-.
-.IP \(bu
-The error-handling policy of
-.I "groff ms"
-is to detect and report errors,
-rather than silently to ignore them.
-.
-.IP \(bu
-Bell Labs localisms are not implemented.
-.
-.IP \(bu
-Berkeley localisms, in particular the
-.B TM
-and
-.B CT
-macros,
-are not implemented.
-.
-.IP \(bu
-.I "Groff ms"
-does not work in compatibility mode (e.g., with the
-.B \-C
-option).
-.
-.IP \(bu
-There is no support for typewriter-like devices.
-.
-.IP \(bu
-.I "Groff ms"
-does not provide cut marks.
-.
-.IP \(bu
-Multiple line spacing is not supported
-(use a larger vertical spacing instead).
-.
-.IP \(bu
-Some Unix
-.I ms
-documentation says that the
-.B CW
-and
-.B GW
-number registers can be used to control the column width and
-gutter width, respectively.
-These number registers are not used in
-.IR "groff ms" .
-.
-.IP \(bu
-Macros that cause a reset
-(paragraphs, headings, etc.\&)
-may change the indent.
-Macros that change the indent do not increment or decrement
-the indent, but rather set it absolutely.
-This can cause problems for documents that define
-additional macros of their own.
-The solution is to use not the
-.B in
-request but instead the
-.B RS
-and
-.B RE
-macros.
-.
-.IP \(bu
-The number register
-.B GS
-is set to\~1 by the
-.I "groff ms"
-macros,
-but is not used by the Unix
-.I ms
-macros.
-Documents that need to determine whether
-they are being formatted with Unix
-.I ms
-or
-.I "groff ms"
-should use this number register.
-.
-.IP \(bu
-To make
-.I "groff ms"
-use the default page offset (which also specifies the left margin),
-the
-.B PO
-number register must stay undefined until the first
-.B ms
-macro is evaluated.
-This implies that
-.B PO
-should not be used early in the document, unless it is changed also:
-Remember that accessing an undefined register automatically defines it.
-.br
-.ne 23
-.

-.SS Strings

-You can redefine the following strings to adapt the
-.I "groff ms"
-macros to languages other than English:
-.TS
-center;
-cb cb
-afCW l .

-.
-.PP
-Use
-.B \[rs]*Q

-to get a left and right typographer's quote,
-respectively, in
-.I troff
-(and plain quotes in

-.SS Text Settings
-.
-The
-.B FAM
-string sets the default font family.
-If this string is undefined at initialization,
-it is set to Times.
-.
-.LP
-The point size, vertical spacing, and inter-paragraph spacing for footnotes
-are controlled by the number registers
-.BR FPS ,
-.BR FVS ,
-and
-.BR FPD ;
-at initialization these are set to
-.BR \[rs]n(PS-2 ,
-.BR \[rs]n[FPS]+2 ,
-and
-.BR \[rs]n(PD/2 ,
-respectively.
-If any of these registers are defined before initialization,
-the initialization macro does not change them.
-.
-.LP
-The hyphenation flags (as set by the
-.B hy
-request) are set from the
-.B HY
-register;
-the default is\~14.
-.
-.PP
-Improved accent marks
-(as originally defined in Berkeley's
-.I ms
-version)
-are available by specifying the
-.B AM
-macro at the beginning of your document.
-You can place an accent over most characters
-by specifying the string defining the accent
-directly after the character.
-For example,
-.B n\[rs]*~ 
-produces an n with a tilde over it.

-.SH "NAMING CONVENTIONS"
-.
-.
-.LP
-The following conventions are used for names of macros, strings and
-number registers.
-External names available to documents that use the
-.I "groff ms"
-macros contain only uppercase letters and digits.
-.
-.LP
-Internally the macros are divided into modules;
-naming conventions are as follows:
-.
-.IP \(bu 3n
-Names used only within one module are of the form
-.IB \%module * name\fR.
-.
-.IP \(bu
-Names used outside the module in which they are defined are of the form
-.IB \%module @ name\fR.
-.
-.IP \(bu
-Names associated with a particular environment are of the form
-.IB \%environment : name\fR;
-these are used only within the
-.B par
-module.
-.
-.IP \(bu
-.I name
-does not have a module prefix.
-.
-.IP \(bu
-Constructed names used to implement arrays are of the form
-.IB \%array ! index\fR.
-.
-.PP
-Thus the groff ms macros reserve the following names:
-.
-.IP \(bu 3n
-Names containing the characters
-.BR * ,
-.BR @ ,
-and\~\c
-.BR : .
-.
-.IP \(bu
-Names containing only uppercase letters and digits.

-.SH DESCRIPTION
-.\" --------------------------------------------------------------------
-.
-The
-.I trace
-macro package of
-.BR groff (@MAN1EXT@)
-can be a valuable tool for debugging documents written in the roff
-formatting language.
-.
-A call stack trace is protocolled on standard error, that means, a
-diagnostic message is emitted on entering and exiting of a macro call.
-.
-This greatly eases to track down an error in some macro.
-.
-.
-.P
-This tracing process is activated by specifying the groff or troff
-command line option
-.BR "-m\~trace" .
-This works also with the
-.BR groffer (@MAN1EXT@)
-viewer program.
-.
-A finer control can be obtained by including the macro file within the
-document by the groff macro call
-.BR ".mso\~trace.tmac" .
-Only macros that are defined after this line are traced.
-.
-.
-.P
-If some other macro package should be traced as well it must be specified
-after
-.BR "-m\~trace"
-on the command line.
-.
-.
-.P
-The macro file
-.B trace.tmac
-is unusual because it does not contain any macros to be called by a
-user.
-.
-Instead, the existing macro definition and appending facilities are
-modified such that they display diagnostic messages.
-.
-.
-.\" --------------------------------------------------------------------
-.SH EXAMPLES
-.\" --------------------------------------------------------------------
-.
-.P
-In the following examples, a roff fragment is fed into groff via
-standard input.
-.
-As we are only interested in the diagnostic messages (standard error)
-on the terminal, the normal formatted output (standard output) is
-redirected into the nirvana device
-.IR /dev/null .
-The resulting diagnostic messages are displayed directly below the
-corresponding example.

-.SH SYNOPSIS
-.B "groff \-mwww"
-[ options ]
-file ...
-.
-.
-.SH DESCRIPTION
-This manual page describes the GNU \-mwww macro package, which is part of
-the groff document formatting system.
-The manual page is very a basic guide, and the html device driver
-.RB ( \%grohtml )
-has been completely rewritten but still remains as in an alpha state.
-It has been included into the distribution so that a lot of people have a
-chance to test it.
-Note that this macro file will be automatically called (via the
-.B troffrc
-file) if you use
-.BR \-Thtml .
-.PP
-To see the hyperlinks in action, please format this man page with the
-.B \%grohtml
-device.
-.PP

-.
-.
-.SH REQUESTS
-.TP
-.B .JOBNAME filename
-Split output into multiple HTML files.
-A file is split whenever a .SH or .NH\ 1 is encountered.
-Its argument is the file stem name for future output files.
-This option is equivalent to
-.BR \%grohtml 's
-.B \-j
-option.
-.TP
-.B .HX n
-Specify the cut off depth when generating links from section headings.
-For example, a parameter of\~2 would cause
-.B \%grohtml
-to generate a list of links for
-.B .NH\ 1
-and
-.B .NH\ 2
-but not for
-.BR .NH\ 3 .
-Whereas
-.RS
-.IP
-.nf
-.B .HX 0
-.fi
-.RE
-.IP
-will tell
-.B \%grohtml
-that no heading links should be created at all.
-Another method for turning automatic headings off is by issuing the
-the command line switch
-.B \-P\-l
-to
-.BR groff .
-.
-.TP
-.B .BCL foreground background active not-visited visited
-This macro takes five parameters: foreground, background, active hypertext
-link, hypertext link not yet visited, and visited hypertext link colour.
-.
-.TP
-.B .BGIMG imagefile
-the only parameter to this macro is the background image file.
-.
-.TP
-.B .URL url [description] [after]
-generates
-.TAG URL
-a URL using either one, two or three arguments.
-The first parameter is the actual URL, the second is the name of the link,
-and the third is optional stuff to be printed immediately afterwards.
-If
-.B description
-and
-.B after
-are absent then the
-.B url
-becomes the anchor text.
-Hyphenation is disabled while printing the actual URL;
-explicit breakpoints
-should be inserted with the
-.B \[rs]:
-escape.
-Here is how to encode
-.URL http://\:foo.\:org/ "foo" :
-.RS
-.IP
-.B .URL http://\[rs]:foo.\[rs]:org/ "foo" :
-.RE
-.IP
-If this is processed by a device other than 
-.B \-Thtml
-it appears as:
-.RS
-.IP
-\m[blue]foo\m[] \[la]\f[C]http://foo.org\f[]\[ra]:
-.RE
-.IP
-The URL macro can be of any type; for example we can reference
-.URL pic.html "Eric Raymond's pic guide" 
-by:
-.RS
-.IP
-.B .URL pic.html \[dq]Eric Raymond's pic guide\[dq]
-.RE
-.
-.TP
-.B .MTO address [description] [after]
-Generate an email html reference.
-The first argument is mandatory as the email address.
-The optional second argument is the text you see in your browser
-If an empty argument is given,
-.B address
-is used instead.
-An optional third argument is stuff printed immediately afterwards.
-Hyphenation is disabled while printing the actual email address.
-For example, 
-.MTO joe@user.org "Joe User"
-was achieved by the following macro:
-.RS
-.IP
-.B .MTO joe@user.org \[dq]Joe User\[dq]
-.RE
-.IP
-Note that all the URLs actually are treated as consuming no textual space
-in groff.
-This could be considered as a bug since it causes some problems.
-To circumvent this,
-.B www.tmac
-inserts a zero-width character which expands to a harmless space (only if
-run with
-.BR \-Thtml ).
-.
-.TP
-.B .FTP url [description] [after]
-indicates that data can be obtained via ftp.
-The first argument is the url and the second is the browser text.
-A third argument, similar to the macros above, is intended for stuff printed
-immediately afterwards.
-The second and the third parameter are optional.
-Hyphenation is disabled while printing the actual URL.
-As an example, here the location of the
-.FTP ftp://\:ftp.gnu.org/ "GNU ftp server" .
-The macro example above was specified by:
-.RS
-.IP
-.B .FTP ftp://\[rs]:ftp.gnu.org/ \[dq]GNU ftp server\[dq] .
-.RE
-.
-.TP
-.B .TAG name
-Generates an html name tag from its argument.
-This can then be referenced using the
-.URL #URL URL
-macro.
-As you can see, you must precede the tag name with
-.B #
-since it is a local reference.
-This link was achieved via placing a TAG in the URL description above;
-the source looks like this:
-.RS
-.IP
-.nf
-.ft B
-\&.TP
-\&.B URL
-generates
-\&.TAG URL
-a URL using either two or three arguments.
-\&.\|.\|.
-.fi
-.ft P
-.RE
-.
-.TP
-.B .IMG [-R|-L|-C] filename [width] [height]
-Include a picture into the document.
-The first argument is the horizontal location: right, left, or center
-.RB ( \-R ,
-.BR \-L ,
-or
-.BR \-C ).
-Alignment is centered by default (-C).
-The second argument is the filename.
-The optional third and fourth arguments are the width and height.
-If the width is absent it defaults to 1\~inch.
-If the height is absent it defaults to the width.
-This maps onto an html img tag.
-If you are including a png image then it is advisable to use the
-.B PIMG
-macro.
-.
-.TP
-.B .PIMG [-R|-L|-C] filename [width [height]]
-Include an image in PNG format.
-This macro takes exactly the same parameters as the
-.B IMG
-macro; it has the advantage of working with postscript and html devices
-also since it can automatically convert the image into the EPS format,
-using the following programs
-of the
-.B netpbm
-package:
-.BR pngtopnm ,
-.BR pnmcrop ,
-and
-.BR pnmtops .
-If the document isn't processed with
-.B \-Thtml
-it is necessary to use the
-.B \-U
-option of groff.
-.
-.TP
-.B .MPIMG [-R|-L] [-G gap] filename [width [height]]
-Place a PNG image on the margin and wrap text around it.
-The first parameters are optional.
-The alignment: left or right
-.RB ( \-L
-or
-.BR \-R )
-specifies the margin where the picture is placed at.
-The default alignment is left
-.RB ( -L ).
-Optionally,
-.BI \-G \~gap
-can be used to arrange a gap between the picture
-and the text that wraps around it.
-The default gap width is zero.
-.br
-The first non-optional argument is the filename.
-The optional following arguments are the width and height.
-If the width is absent it defaults to 1\~inch.
-If the height is absent it defaults to the width.
-Example:
-.RS
-.IP
-.nf
-.ft B
-\&.MPIMG -L -G 2c foo.png 3c 1.5c
-.ft P
-.fi
-.RE
-.IP
-The height and width may also be given as percentages. The PostScript
-device calculates the width from the
-.B .l
-register and the height from the
-.B .p
-register. For example:
-.RS
-.IP
-.nf
-.ft B
-\&.MPIMG -L -G 2c foo.png 15%
-.ft P
-.fi
-.RE
-.
-.TP
-.B .HnS n
-Begin heading.
-The numeric heading level
-.I n
-is specified by the first parameter.
-Use this macro if your headings contain URL, FTP or MTO macros.
-Example:
-.RS
-.IP
-.nf
-.ft B
-\&.HnS 1
-\&.HR
-GNU Troff
-\&.URL http://groff.ffii.org (Groff) 
-\&\(em a
-\&.URL http://www.gnu.org/ GNU
-\&project.
-\&Hosted by
-\&.URL http://ffii.org/ FFII .
-\&.HR
-\&.HnE
-.ft P
-.fi
-.RE
-.IP
-In this case you might wish to
-disable automatic links to headings.
-This can be done via
-.B \-P\-l
-from the command line.
-.\" or by using a call to `.HX 0'.
-
-.
-.TP
-.B .HnE
-End heading.
-.
-.TP
-.B .LK
-.TAG LK
-Force \%grohtml to place the automatically generated links at this position.
-If this manual page has been processed with
-.B \-Thtml
-those links can be seen right here.
-.
-.LK
-.
-.TP
-.B .HR
-Generate a full-width horizontal rule for
-.BR \-Thtml .
-No effect for all other devices.
-.
-.TP
-.B .NHR
-Suppress generation of the top and bottom rules which \%grohtml emits
-by default.
-.
-.TP
-.B .HTL
-Generate an HTML title only.
-This differs from the 
-.B TL
-macro of the
-.B ms
-macro package which generates both an HTML title and an <H1> heading.
-Use it to provide an HTML title as search engine fodder but a graphic title
-in the document.
-The macro terminates when a space or break is seen (.sp, .br).
-.
-.TP
-.B .HEAD
-Add arbitrary HTML data to the <head> block.
-Ignored if not processed with
-.BR \-Thtml .
-Example:
-.RS
-.IP
-.nf
-.B ".HEAD" "\[dq]<link \[rs]"
-.B "  rel=\[dq]\[dq]icon\[dq]\[dq] \[rs]"
-.B "  type=\[dq]\[dq]image/png\[dq]\[dq] \[rs]"
-.B "  href=\[dq]\[dq]http://foo.org//bar.png\[dq]\[dq]/>\[dq]"
-.fi
-.ft P
-.RE
-.
-.TP
-.B .HTML
-All text after this macro is treated as raw html.
-If the document is processed without
-.B \-Thtml
-then the macro is ignored.
-Internally, this macro is used as a building block for other higher-level
-macros.
-.IP
-For example, the
-.B BGIMG
-macro is defined as
-.RS
-.IP
-.nf
-.ft B
-\&.de BGIMG
-\&.   HTML <body background=\[rs]$1>
-\&..
-.ft P
-.fi
-.RE
-.
-.TP
-.B .DC l text [color]
-Produce a drop capital.
-The first parameter is the letter to be dropped and enlarged, the second
-parameter
-.B text
-is the ajoining text whose height the first letter should not exceed.
-The optional third parameter is the color of the dropped letter.
-It defaults to black.
-.
-.TP
-.B ".CDS"
-Start displaying a code section in constant width font.
-.
-.TP
-.B ".CDE"
-End code display
-.
-.SH SECTION HEADING LINKS
-By default
-.B \%grohtml
-generates links to all section headings and places these at the top of the
-html document. (See
-.URL #LK LINKS
-for details of how to switch this off or alter the position).

-.\"   groff ... -dpaper=<format> ...
-.\"
-.\" Possible values for `format' are the same as the predefined `papersize'

 <li>xei_version is the version number of the API as implemented within libxo. This version is currently as 1 using XO_ENCODER_VERSION. This number can be checked to ensure compatibility. The working assumption is that all versions should be backward compatible, but each side may need to accurately know the version supported by the other side. xo_encoder_library_init can optionally check this value, and must then set it to the version number used by the encoder, allowing libxo to detect version differences and react accordingly. For example, if version 2 adds new operations, then libxo will know that an encoding library that set xei_version to 1 cannot be expected to handle those new operations.</li>
 <li>xei_handler must be set to a pointer to a function of type xo_encoder_func_t, as defined in xo_encoder.h. This function takes a set of parameters: -- xop is a pointer to the opaque xo_handle_t structure -- op is an integer representing the current operation -- name is a string whose meaning differs by operation -- value is a string whose meaning differs by operation -- private is an opaque structure provided by the encoder</li>

+pairs or single colors.
+
+For example consider the following xo_emit call:
+
+    xo_emit("{C:fg-red,bg-green}Merry XMas!!{C:}\n");
+
+To turn all colored output to red-on-blue, use eight pairs of
+"red/blue" mappings separated by "+"s:
+
+    --libxo colors=red/blue+red/blue+red/blue+red/blue+\
+                   red/blue+red/blue+red/blue+red/blue
+
+To turn the red-on-green text to magenta-on-cyan, give a "magenta"
+foreground value for red (the second mapping) and a "cyan" background
+to green (the third mapping):
+
+    --libxo colors=+magenta+/cyan
+
+Consider the common situation where blue output looks unreadable on a
+terminal session with a black background.  To turn both "blue"
+foreground and background output to "yellow", give only the fifth
+mapping, skipping the first four mappings with bare "+"s:
