=head1 SYNOPSIS

  package MyApp::Controller::Metalic;
  use parent 'Catalyst::Controller::Metal';

  sub call {
      my($self, $env) = @_;
      if ($env->{PATH_INFO} =~ m!^/hello!) {
          return [ 200, [ "Content-Type" => 'text/plain' ], [ "Hello World" ] ];
      } else {
          return [ 404, [], [] ];

Catalyst::Controller::Metal allows you to write a raw PSGI handler in
your Catalyst application, inspired by Rails Metal that allows you to
write raw Rack applications inside Ruby on Rails.
