=head1 NAME
ZoneMinder::Database - Perl extension for blah blah blah
=head1 SYNOPSIS
use ZoneMinder::Object;
This package should likely not be used directly, as it is meant mainly to be a parent for all other ZoneMinder classes.
=head1 DESCRIPTION
Stub documentation for ZoneMinder, created by h2xs. It looks like the
author of the extension was negligent enough to leave the stub
unedited.
Blah blah blah.
=head2 EXPORT
None by default.
=head1 SEE ALSO
Mention other useful documentation such as the documentation of
related modules or operating system documentation (such as man pages
in UNIX), or any relevant external documentation such as RFCs or
standards.
If you have a mailing list set up for your module, mention it here.
If you have a web site set up for your module, mention it here.
