/* 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.
