+Allows you to set the attributes that the dispatcher creates actions out of.
+This allows you to do 'rails style routes', or override some of the
+attribute defintions of actions composed from Roles.
+You can set arguments globally (for all actions of the controller) and
+specifically (for a single action).

+In the case above every sub in the package would be made into a Chain
+endpoint with a URI the same as the sub name for each sub, chained
+to the sub named C<base>. Ergo dispatch to C</example> would call the
+C<base> method, then the C<example> method.
+
+=head2 action_args
+
+Allows you to set constructor arguments on your actions. You can set arguments
+globally and specifically (as above).
+This is particularly useful when using C<ActionRole>s
+(L<Catalyst::Controller::ActionRole>) and custom C<ActionClass>es.
