  * Overview of event dispatch and subscribing
  *
  * @section sec_intro Introduction and terminology
- * Events are part of the Symfony framework: they allow for different components
- * of the system to interact and communicate with each other. Each event has a
- * unique string name. One system component dispatches the event at an
- * appropriate time; many events are dispatched by Drupal core and the Symfony
- * framework in every request. Other system components can register as event
- * subscribers; when an event is dispatched, a method is called on each
- * registered subscriber, allowing each one to react. For more on the general
- * concept of events, see
