=head1 NAME

P5U::Lib::TestPod - support library implementing p5u's testpod command

=head1 SYNOPSIS

 use P5U::Lib::TestPod;
 P5U::Lib::TestPod->test_pod(@files);

=head1 DESCRIPTION

This is a support library for the testpod command.

=head2 Class Method

There's only one method (a class method, not an object method... this
isn't really an OO module) worth caring about:

=over

=item C<< test_pod(@files) >>

Tests the pod in given files. Writes TAP to STDOUT.

Actually, some of the files can be directories, in which case those
directories will be scanned for Perl modules, scripts and pod files.
