=head1 DESCRIPTION

See L<Bugzilla::JobQueue> and L<Bugzilla::JobQueue::Runner>.

=head1 Running jobqueue.pl as a System Service

For systems that use Upstart or SysV Init, there is a SysV/Upstart init
script included with Bugzilla for jobqueue.pl: F<contrib/bugzilla-queue>.
It should work out-of-the-box on RHEL, Fedora, CentOS etc.

You can install it by doing C<./jobqueue.pl install> as root, after
already having run L<checksetup> at least once to completion
on this Bugzilla installation.

If you are using a system that isn't RHEL, Fedora, CentOS, etc., then you
may have to modify F<contrib/bugzilla-queue> and install it yourself
manually in order to get C<jobqueue.pl> running as a system service.
