=head1 NAME

Mytest2 - Perl extension for blah blah blah

=head1 SYNOPSIS

use Mytest2;
blah blah blah

=head1 DESCRIPTION

Stub documentation for Mytest2, 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.

=head2 Exportable constants

TESTVAL



=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.
