=head1 DESCRIPTION

A Catalyst extension to replace the development server with L<Starman>.

This module replaces the functionality of L<Catalyst::Engine::HTTP::Prefork>,
which is now deprecated.

It provides access to the prefork engine specific options which were previously
added by hacking your server script.

=head1 Adding this to your application

Just add a server script module to your application which inherits from this
package.

L<Catalyst::ScriptRunner> will automatically detect and use it when
script/myapp_server.pl is started.

For example:

    package MyApp::Script::Server;
    use Moose;
    use namespace::autoclean;

    extends 'CatalystX::Script::Server::Starman';
