=head1 DESCRIPTION
This is the Catalyst engine specialized for the CGI environment (using the
-C<CGI::Simple> and C<CGI::Cookie> modules). Normally Catalyst will select the
-appropriate engine according to the environment that it detects, however you
-can force Catalyst to use the CGI engine by specifying the following in your
-application module:
-
- use Catalyst qw(-Engine=CGI);
-
-Catalyst::Engine::CGI generates a full set of HTTP headers, which means that
-applications using the engine must be be configured as "Non-parsed Headers"
-scripts (at least when running under Apache). To configure this under Apache
-name the starting with C<nph->.
-
-The performance of this way of using Catalyst is not expected to be
-useful in production applications, but it may be helpful for development.
