=head1 NAME
Template::Plugin::Class - allow calling of class methods on arbitrary classes
=head1 SYNOPSIS
  [% USE foo = Class('Foo') %]
  [% foo.bar %]
=head1 DESCRIPTION
Template::Plugin::Class allows you to call class methods on
arbitrary classes.  One use for this is in Class::DBI style
applications, where you may do somthing like this:
  [% USE cd = Class('Music::CD') %]
  [% FOREACH disc = cd.retrieve_all %]
  [% disc.artist %] - [% disc.title %]
  [% END %]
=head1 CAVEATS
You won't be able to directly call C<AUTOLOAD> or C<DESTROY> methods
on the remote class.  This shouldn't be a huge hardship.
=head1 BUGS
Apart from the mentioned caveat, none currently known.  If you find
any please contact the author.
