-		 *
-		 * MediaWiki has various interface components that are extended, enhanced

-		 * in core itself.
-		 *
-		 * This framework helps streamlining the timing of when these other
-		 * code paths fire their plugins (instead of using document-ready,
-		 * which can and should be limited to firing only once).
-		 *
-		 * Features like navigating to other wiki pages, previewing an edit
-		 * and editing itself – without a refresh – can then retrigger these
-		 * hooks accordingly to ensure everything still works as expected.
-		 *
-		 * Example usage:
-		 *
-		 *     mw.hook( 'wikipage.content' ).add( fn ).remove( fn );
-		 *     mw.hook( 'wikipage.content' ).fire( $content );
-		 *
-		 * Handlers can be added and fired for arbitrary event names at any time. The same
-		 * event can be fired multiple times. The last run of an event is memorized
-		 * (similar to `$(document).ready` and `$.Deferred().done`).
-		 * This means if an event is fired, and a handler added afterwards, the added
-		 * function will be fired right away with the last given event data.
-		 *
-		 * Like Deferreds and Promises, the mw.hook object is both detachable and chainable.
-		 * Thus allowing flexible use and optimal maintainability and authority control.
-		 * You can pass around the `add` and/or `fire` method to another piece of code
-		 * without it having to know the event name (or `mw.hook` for that matter).
-		 *
-		 *     var h = mw.hook( 'bar.ready' );
-		 *     new mw.Foo( .. ).fetch( { callback: h.fire } );
-		 *
-		 * Note: Events are documented with an underscore instead of a dot in the event
-		 * name due to jsduck not supporting dots in that position.
