CGI::Application is intended to make it easier to create sophisticated,
reusable web-based applications. This module implements a methodology which,
if followed, will make your web software easier to design, easier to
document, easier to write, and easier to evolve.

The guiding philosophy behind CGI::Application is that a web-based
application can be organized into a specific set of "Run-Modes." Each
Run-Mode is roughly analogous to a single screen (a form, some output, etc).
All the Run-Modes are managed by a single "Application Module" which is a
Perl module. In your web server's document space there is an "Instance
Script" which is called by the web server as a CGI (or an Apache::Registry
script if you're using Apache + mod_perl).

CGI::Application is an Object-Oriented Perl module which implements an
Abstract Class. It is not intended that this package be instantiated
directly. Instead, it is intended that your Application Module will be
implemented as a Sub-Class of CGI::Application.
