-/* This program is derived from 4.3 BSD software and is
-   subject to the copyright notice below.
-
-   The port to HP-UX has been motivated by the incapability
-   of 'rlogin'/'rlogind' as per HP-UX 6.5 (and 7.0) to transfer window sizes.
-
-   Changes:
-
-   - General HP-UX portation. Use of facilities not available
-     in HP-UX (e.g. setpriority) has been eliminated.
-     Utmp/wtmp handling has been ported.
-
-   - The program uses BSD command line options to be used
-     in connection with e.g. 'rlogind' i.e. 'new login'.
-
-   - HP features left out:         password expiry
-                                   '*' as login shell, add it if you need it
-
-   - BSD features left out:         quota checks
-                                   password expiry
-                                   analysis of terminal type (tset feature)
-
-   - BSD features thrown in:        Security logging to syslogd.
-                                    This requires you to have a (ported) syslog
-                                   system -- 7.0 comes with syslog
-
-                                   'Lastlog' feature.
-
-   - A lot of nitty gritty details have been adjusted in favour of
-     HP-UX, e.g. /etc/securetty, default paths and the environment
-     variables assigned by 'login'.
-
-   - We do *nothing* to setup/alter tty state, under HP-UX this is
-     to be done by getty/rlogind/telnetd/some one else.

-
-   1991-09-24 glad@daimi.aau.dk: HP-UX 8.0 port:
-   - now explictly sets non-blocking mode on descriptors
-   - strcasecmp is now part of HP-UX
-
-   1992-02-05 poe@daimi.aau.dk: Ported the stuff to Linux 0.12
-   From 1992 till now (1997) this code for Linux has been maintained at
-   ftp.daimi.aau.dk:/pub/linux/poe/
-
-   1999-02-22 Arkadiusz Mi¶kiewicz <misiek@pld.ORG.PL>
-    - added Native Language Support
-   Sun Mar 21 1999 - Arnaldo Carvalho de Melo <acme@conectiva.com.br>
-    - fixed strerr(errno) in gettext calls
