=head1 NAME
Pod::Perldoc::ToPod - let Perldoc render Pod as ... Pod!
=head1 SYNOPSIS
perldoc -opod Some::Modulename
(That's currently the same as the following:)
perldoc -u Some::Modulename
=head1 DESCRIPTION
This is a "plug-in" class that allows Perldoc to display Pod source as
itself! Pretty Zen, huh?
Currently this class works by just filtering out the non-Pod stuff from
a given input file.
