* libulog.
*
* This library is provided as a migratory tool towards <utmpx.h>. We
* cannot yet implement <utmpx.h>, because our on-disk file format lacks
* various fields. <utmpx.h> also has some shortcomings. Ideally we
* want to allow logging of user login records generated by unprivileged
* processes as well, provided that they hold a file descriptor to a
* pseudo-terminal master device.
*
* Unlike struct utmpx, the buffers containing the strings are not
* stored inside struct ulog_utmpx itself. Processes should never
* handcraft these structures anyway.
*
* This library (or at least parts of it) will hopefully deprecate over
* time, when we provide the <utmpx.h> API.
