DESCRIPTION
    This module is EXPERIMENTAL

    This module provides a declarative syntax for Catalyst applications. Its
    main focus is currently on common and repetitious parts of the
    application, such as the application class itself, controllers, and
    controller roles.

  Not a Source Filter
    The used syntax elements are not parsed via source filter mechanism, but
    through Devel::Declare, which is a much less fragile deal to handle and
    allows extensions to mix without problems. For example, all keywords
    added by this module are separete handlers.

  Syntax Documentation
    The documentation about syntax is in the respective parts of the
    distribution below the "CatalystX::Declare::Keyword::" namespace. Here
    are the manual pages you will be interested in to familiarize yourself
    with this module's syntax extensions:

    CatalystX::Declare::Keyword::Application
    CatalystX::Declare::Keyword::Action
    CatalystX::Declare::Keyword::Controller
    CatalystX::Declare::Keyword::Role
    CatalystX::Declare::Keyword::View
    CatalystX::Declare::Keyword::Model

    Things like models, views, roles for request or response objects, can be
    built declaratively with MooseX::Declare, which is used to additionally
    provide keywords for "class", "role", "method" and the available method
    modifier declarations. This allows for constructs such as:

        use CatalystX::Declare;

        class Foo {

            method bar { 23 }
        }

        controller MyApp::Web::Controller::Baz {

            final action qux under '/' { 
                $ctx->response->body(Foo->new->bar) 
            }
        }

  For Usage Information
    These links are intended for the common user of this module.

    Catalyst::Runtime
    Catalyst::Devel
    Catalyst::Manual
        Although you probably already know Catalyst, since you otherwise
        probably wouldn't be here, I include these links for completeness
        sake.

    Moose
        The powerful modern Perl object orientation implementation that is
        used as basis for Catalyst. MooseX::Declare, on which
        CatalystX::Declare is based, provides a declarative syntax for
        Moose.

    MooseX::Declare
        We inherit almost all functionality from MooseX::Declare to allow
        the declaration of traditional classes, roles, methods, modifiers,
        etc. Refer to this documentation first for syntax elements that
        aren't part of CatalystX::Declare.

    MooseX::Method::Signatures
        This isn't directly used, but MooseX::Declare utilises this to
        provide us with method and modifier declarations. For extended
        information on the usage of methods, especially signatures, refer to
        this module after looking for an answer in the MooseX::Declare
        documentation.

  For Developer Information
    This section contains links relevant to the implementation of this
    module.

    Devel::Declare
        You could call this is the basic machine room that runs the
        interaction with perl. It provides a way to hook into perl's source
        code parsing and change small parts on a per-statement basis.

    MooseX::MethodAttributes
        We use this module to easily communicate the action attributes to
        Catalyst. Currently, this is the easiest solution for now but may be
        subject to change in the future.
