# bugzilla-queue This starts, stops, and restarts the Bugzilla jobqueue.pl

### BEGIN INIT INFO
# Provides: bugzilla-queue
# Required-Start: $local_fs $syslog
# Required-Stop: $local_fs $syslog
# Default-Start: 3 5
# Default-Stop: 0 1 2 6
# Short-Description: Start and stop the Bugzilla queue runner.
# Description: The Bugzilla queue runner (jobqueue.pl) sends any mail
#	that Bugzilla has queued to be sent in the background. If you
#	have enabled the use_mailer_queue parameter in Bugzilla, you
#	must run this daemon.
