Jobs.pl #1

#
# Example trigger to enforce a rule "submissions must have a job associated
# with them."
#
# This script will do the following:
#	1. Return "success" (exit code 0) if the change has
#	   at least one "job" associated with it;
#	2. Otherwise, reports an error.
#
# Unix usage:
#	perl /whatever/Jobs.pl %changelist% %serverport% %client%
# NT usage:
#       c:/perl/bin/perl  c:/whatever/Jobs.pl %changelist% %serverport% %client%
# (Note that the name of this script might need to be an "8.3" filename,
# depending on the version of Perl you're running.)
#
# Example 'triggers' section:
#    Triggers:
#	exJobs  //...   "c:/perl/bin/perl c:/whatever/Jobs.pl %changelist% %serverport% %client%"
#
# Tested on Platforms:   FreeBSD, NT (as program, not service).
#
# Known bugs:
#	1. Perforce triggers have problems [at the moment] running when the
#	   Perforce server is running as an NT server.
