=head1 NAME

zmaudit.pl - ZoneMinder event file system and database consistency checker

=head1 SYNOPSIS

 zmaudit.pl [-r,-report|-i,-interactive]

=head1 DESCRIPTION

This script checks for consistency between the event filesystem and
the database. If events are found in one and not the other they are
deleted (optionally). Additionally any monitor event directories that
do not correspond to a database monitor are similarly disposed of.
However monitors in the database that don't have a directory are left
alone as this is valid if they are newly created and have no events
yet.

=head1 OPTIONS

 -r, --report               - Just report don't actually do anything
 -i, --interactive          - Ask before applying any changes
 -c, --continuous           - Run continuously
 -v, --version              - Print the installed version of ZoneMinder

use constant MAX_AGED_DIRS => 10; # Number of event dirs to check age on
