** The main contributors have been (in no special order):
**
** Glen Eustace <[e-mail]>
**    user name caching for b-i-g password files
** Paul Emerson <[e-mail]>
**    cleaning up Interactive 386/ix handling, fixing the lp
**    interface, and generally tidying up the sources
** Keith Ericson <[e-mail]>
**    more 386/ix fixes
** Jeff Stearns <[e-mail]>
**    setuid/setgid for lpr
** Peter Van Campen <[e-mail]>
**    fixing setuid/gid stuff, syslog
** Ted Nolan <[e-mail]>
**    /usr/adm/wtmp, other security suggestions
** Mogens Trab Damsgaard <[e-mail]>
**    allow SVR4 and BSD names to be used as appropriate.
** Arthur David Olson <[e-mail]>
**    dozens of fixes all over the place
** Phil Servita <[e-mail]>
**    Ultrix authentication
** Greg Hinkel <[e-mail]>
