-module ActionController #:nodoc:

-    def self.included(base)
-      base.extend(ClassMethods)
-    end
-
-    # Dependencies control what classes are needed for the controller to run its course. This is an alternative to doing explicit
-    # +require+ statements that bring a number of benefits. It's more succinct, communicates what type of dependency we're talking about,
-    # can trigger special behavior (as in the case of +observer+), and enables Rails to be clever about reloading in cached environments
-    # like FCGI. Example:
-    #
-    #   class ApplicationController < ActionController::Base
-    #     model    :account, :company, :person, :project, :category
-    #     helper   :access_control
-    #     service  :notifications, :billings
-    #     observer :project_change_observer
-    #   end
-    #
-    # Please note that a controller like ApplicationController will automatically attempt to require_dependency on a model of its 
-    # singuralized name and a helper of its name. If nothing is found, no error is raised. This is especially useful for concrete 
-    # controllers like PostController:
-    #
-    #   class PostController < ApplicationController
-    #     # model  :post (already required)
-    #     # helper :post (already required)
-    #   end
-    #
-    # Also note, that if the models follow the pattern of just 1 class per file in the form of MyClass => my_class.rb, then these
-    # classes don't have to be required as Active Support will auto-require them.
-    module ClassMethods #:nodoc:
-      # Specifies a variable number of models that this controller depends on. Models are normally Active Record classes or a similar
-      # backend for modelling entity classes.

-        require_dependencies(:model, models)
-        depend_on(:model, models)

-      # Action Mailer service or a Payment Gateway service.

-        require_dependencies(:service, services)
-        depend_on(:service, services)

-      # Specifies a variable number of observers that are to govern when this controller is handling actions. The observers will
-      # automatically have .instance called on them to make them active on assignment.
