-/*********************** Notes for the BIND 4.9 release (Paul Vixie, DEC)
- * dig 2.0 was written by copying sections of libresolv.a and nslookup
- * and modifying them to be more useful for a general lookup utility.
- * as of BIND 4.9, the changes needed to support dig have mostly been
- * incorporated into libresolv.a and nslookup; dig now links against
- * some of nslookup's .o files rather than #including them or maintaining
- * local copies of them. in some sense, dig belongs in the nslookup
- * subdirectory rather than up here in "tools", but that's for arc@sgi.com
- * (owner of nslookup) to decide.
- *
- * while merging dig back into the BIND release, i made a number of
- * structural changes. for one thing, i put all of dig's private
- * library routines into this file rather than maintaining them in
- * separate, #included, files. i don't like to #include ".c" files.
- * i removed all calls to "bcopy", replacing them with structure
- * assignments. i removed all "extern"'s of standard functions,
- * replacing them with #include's of standard header files. this
- * version of dig is probably as portable as the rest of BIND.
- *
- * i had to remove the query-time and packet-count statistics since
- * the current libresolv.a is a lot harder to modify to maintain these
- * than the 4.8 one (used in the original dig) was. for consolation,
- * i added a "usage" message with extensive help text.
- *
- * to save my (limited, albeit) sanity, i ran "indent" over the source.
- * i also added the standard berkeley/DEC copyrights, since this file now
- * contains a fair amount of non-USC code. note that the berkeley and
- * DEC copyrights do not prohibit redistribution, with or without fee;
- * we add them only to protect ourselves (you have to claim copyright
- * in order to disclaim liability and warranty).
