# Below is stub documentation for your module. You'd better edit it!
=head1 NAME
OpenBSDTorrents - Perl extension for blah blah blah
=head1 SYNOPSIS
use OpenBSDTorrents;
blah blah blah
=head1 DESCRIPTION
Stub documentation for OpenBSDTorrents, created by h2xs. It looks like the

unedited.
Blah blah blah.

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.
