=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.
