+=item C<delay_flash_on_redirect>
+
+May be overridden by a controller. If this method returns true, redirect_to
+will delay all flash messages for the current request. Defaults to false for
+compatibility reasons.
+
+=item C<get_auth_level $action>
+
+May be overridden by a controller. Determines what kind of
+authentication is required for a particular action. Must return either
+C<admin> (which means that authentication as an admin is required),
+C<user> (authentication as a normal user suffices) with a possible
+future value C<none> (which would require no authentication but is not
+yet implemented).
+
+=item C<keep_auth_vars_in_form %params>
+
+May be overridden by a controller. If falsish (the default) all form
+variables whose name starts with C<{AUTH}> are removed before the
+request is routed. Only controllers that handle login requests
+themselves should return trueish for this function.
+
+C<$params{action}> contains the action name that the request will be
+dispatched to.
+
+=item C<controller_name>
+
+Returns the name of the curernt controller package without the
+C<SL::Controller::> prefix. This method can be called both as a class
+method and an instance method.
+
+=item C<action_name>
+
+Returns the name of the currently executing action. If the dispatcher
+mechanism was used then this is not C<dispatch> but the actual method
+name the dispatching resolved to.
+
+=item C<presenter>
+
+Returns the global presenter object by calling
+L<SL::Presenter/get>.
