=head1 DESCRIPTION

C<Apache2::ASP::FormHandler> is an empty subclass of L<Apache2::ASP::HTTPHandler>
and adds nothing of its own.

It provides a starting point for all other form handlers.

All form handlers should inherit from C<Apache2::ASP::FormHandler> or one of its
subclasses.

Although the author is a B<Big Fan> of MVC, he does not like to be constantly beat 
over the head with the MVC two-by-four.

The style of MVC available here is very much like that found in ASP.Net's MVC, 
though somehow it predates the ASP.Net version by more than 2 years.
