- * SpecialPage: handling special pages and lists thereof

- * execute() method, which sends the HTML for the special page to $wgOut.
- * The parent class has an execute() method which distributes the call to

- * user has the necessary access privileges and bails out if not.
+ * SpecialPage: handling special pages and lists thereof.
*
- * To add a special page at run-time, use SpecialPage::addPage().
- * DO NOT manipulate this array at run-time.
+ * To add a special page in an extension, add to $wgSpecialPages either
+ * an object instance or an array containing the name and constructor
+ * parameters. The latter is preferred for performance reasons.
+ *
+ * The object instantiated must be either an instance of SpecialPage or a
+ * sub-class thereof. It must have an execute() method, which sends the HTML
+ * for the special page to $wgOut. The parent class has an execute() method
+ * which distributes the call to the historical global functions. Additionally,
+ * execute() also checks if the user has the necessary access privileges
+ * and bails out if not.
+ *
+ * To add a core special page, use the similar static list in
+ * SpecialPage::$mList. To remove a core static special page at runtime, use
+ * a SpecialPage_initList hook.
