DESCRIPTION
    The key concept of Catalyst is DRY (Don't Repeat Yourself).

    See Catalyst::Manual for more documentation.

    Catalyst plugins can be loaded by naming them as arguments to the "use
    Catalyst" statement. Omit the "Catalyst::Plugin::" prefix from the
    plugin name, so "Catalyst::Plugin::My::Module" becomes "My::Module".

        use Catalyst 'My::Module';

    Special flags like -Debug and -Engine can also be specifed as arguments
    when Catalyst is loaded:

        use Catalyst qw/-Debug My::Module/;

    The position of plugins and flags in the chain is important, because
    they are loaded in exactly the order that they appear.

    The following flags are supported:

    -Debug
        enables debug output, i.e.:

            use Catalyst '-Debug';

        this is equivalent to:

            use Catalyst;
            sub debug { 1 }

    -Engine
        Force Catalyst to use a specific engine. Omit the
        "Catalyst::Engine::" prefix of the engine name, i.e.:

            use Catalyst '-Engine=CGI';

METHODS
    debug
        Overload to enable debug messages.

    config
        Returns a hashref containing your applications settings.

    $c->engine
        Contains the engine class.

    $c->log
        Contains the logging object. Unless it is already set Catalyst sets
        this up with a "Catalyst::Log" object. To use your own log class:

            $c->log( MyLogger->new );
            $c->log->info("now logging with my own logger!");

        Your log class should implement the methods described in the
        "Catalyst::Log" man page.

    $c->plugin( $name, $class, @args )
        Instant plugins for Catalyst. Classdata accessor/mutator will be
        created, class loaded and instantiated.

            MyApp->plugin( 'prototype', 'HTML::Prototype' );

            $c->prototype->define_javascript_functions;

CASE SENSITIVITY
    By default Catalyst is not case sensitive, so "MyApp::C::FOO::Bar"
    becomes "/foo/bar".

    But you can activate case sensitivity with a config parameter.

        MyApp->config->{case_sensitive} = 1;

LIMITATIONS
    mod_perl2 support is considered experimental and may contain bugs.
