=head1 NAME
zmfilter.pl - ZoneMinder tool to filter events
=head1 SYNOPSIS
zmfilter.pl [-f <filter name>,--filter=<filter name>] [--filter_id=<filter id>] | -v, --version
=head1 DESCRIPTION
This script continuously monitors the recorded events for the given
monitor and applies any filters which would delete and/or upload
matching events.
=head1 OPTIONS
-f{filter name}, --filter={filter name} - The name of a specific filter to run
--filter_id={filter id} - The id of a specific filter to run
-v, --version - Print ZoneMinder version
