-=head1 NAME
-
-Catalyst::Engine::HTTP - Catalyst HTTP Engine
-
-=head1 SYNOPSIS
-
-A script using the Catalyst::Engine::HTTP module might look like:
-
- #!/usr/bin/perl -w
-
- BEGIN { $ENV{CATALYST_ENGINE} = 'HTTP' }
-
- use strict;
- use lib '/path/to/MyApp/lib';
- use MyApp;
-
- MyApp->run;
-
-=head1 DESCRIPTION
-
-This is the Catalyst engine specialized for development and testing.
-
