=head1 NAME

zmsystemctl.pl - ZoneMinder systemctl wrapper

=head1 SYNOPSIS

 zmsystemctl.pl {start|stop|restart|version}

=head1 DESCRIPTION

This is a wrapper script that allows zoneminder to start and stop itself
in a manner that keeps it in-sync with systemd.  This script is intended
to be called internally by zoneminder and may not give the desired results
if run from the command line.
