=head1 NAME
zmdc.pl - ZoneMinder Daemon Control script
=head1 SYNOPSIS
zmdc.pl {command} [daemon [options]]
=head1 DESCRIPTION
This script is the gateway for controlling the various ZoneMinder
daemons. All starting, stopping and restarting goes through here.
On the first invocation it starts up a server which subsequently
records what's running and what's not. Other invocations just
connect to the server and pass instructions to it.
=head1 OPTIONS
{command} - One of 'startup|shutdown|status|check|logrot' or
'start|stop|restart|reload|version'.
[daemon [options]] - Daemon name and options, required for second group of commands
