+* Extension of the Symfony2 EventDispatcher
+*
+* It provides an additional `trigger_event` method, which
+* gives some syntactic sugar for dispatching events. Instead
+* of creating the event object, the method will do that for
+* you.
+*
+* Example:
+*
+*     $vars = array('page_title');
+*     extract($phpbb_dispatcher->trigger_event('core.index', compact($vars)));
