  23 ** it (it won't lint 100%, very little does, and there are bugs in
  24 ** some versions of lint :-), and send it back to Sun via email
  25 ** so that we can roll it into the source base and redistribute

  32 ** Glen Eustace <G.Eustace@massey.ac.nz>
  33 **    user name caching for b-i-g password files
  34 ** Paul Emerson <paul@sdgsun.uucp>
  35 **    cleaning up Interactive 386/ix handling, fixing the lp
  36 **    interface, and generally tidying up the sources
  37 ** Keith Ericson <keithe@sail.labs.tek.com>
  38 **    more 386/ix fixes
  39 ** Jeff Stearns <jeff@tc.fluke.com>
  40 **    setuid/setgid for lpr
  41 ** Peter Van Campen <petervc@sci.kun.nl>
  42 **    fixing setuid/gid stuff, syslog
  43 ** Ted Nolan <ted@usasoc.soc.mil>
  44 **    /usr/adm/wtmp, other security suggestions
  45 **
  46 ** Thanks to everyone who has contributed.
