=head1 SYNOPSIS

    # lib/MyApp/View/Download/HTML.pm
    package MyApp::View::Download::HTML;
    use base qw( Catalyst::View::Download::HTML );
    1;

    # lib/MyApp/Controller/SomeController.pm
    sub example_action_1 : Local {
        my ($self, $c) = @_;

        my $content = "Some Text";

        # To output your data just pass your content into the 'html' key of the stash
        $c->stash->{'html'} = $content;

        # Or into the body of the response for this action
        $c->response->body($content);

        # Finally forward processing to the HTML View
        $c->forward('MyApp::View::Download::HTML');
    }

=head1 DESCRIPTION

Takes content and outputs the content as html text.

=head1 SUBROUTINES

=head2 process

This method will be called by Catalyst if it is asked to forward to a component
without a specified action.

=head2 render

Allows others to use this view for much more fine-grained content generation.

=head1 CONFIG

=over 4

=item stash_key

Determines the key in the stash this view will look for when attempting to
retrieve content to process. If this key isn't found it will then look at
$c->response->body for content.

  $c->view('MyApp::View::Download::HTML')->config->{'stash_key'} = 'content';
