+      # This module contains various useful helper methods
+      # that either tie into ActionView or the rest of the ActionPack stack,
+      # or are only useful in that context.
+      # Thus, the methods defined here are only available
+      # if ActionView is installed.
+      module ActionViewExtensions
+        # Returns a value for the "class" attribute
+        # unique to this controller/action pair.
+        # This can be used to target styles specifically at this action or controller.
+        # For example, if the current action were EntryController#show,
+        #
+        #   %div{:class => page_class} My Div
+        #
+        # would become
+        #
+        #   <div class="entry show">My Div</div>
+        #
+        # Then, in a stylesheet
+        # (shown here as Sass),
+        # you could refer to this specific action:
+        #
+        #   .entry.show
+        #     :font-weight bold
+        #
+        # or to all actions in the entry controller:
+        #
+        #   .entry
+        #     :color #00f
+        # 
+        def page_class
