 =head1 DESCRIPTION
 
-This is a handler for Maypole which will use the CGI instead of Apache's
-C<mod_perl> 1.x. This handler can also be used for Apache 2.0.
+This is a CGI platform driver for Maypole. Your application can inherit from
+CGI::Maypole directly, but it is recommended that you use
+L<Maypole::Application>.
+
+This module requires CGI::Simple which you will have to install yourself via CPAN or manually.
