 /**
- * SpecialPage: handling special pages and lists thereof.
+ * Parent class for all special pages.
  *
- * 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.
+ * This program is free software; you can redistribute it and/or modify
+ * it under the terms of the GNU General Public License as published by

  *
- * 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.

+ * GNU General Public License for more details.
  *
- * 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.
+ * You should have received a copy of the GNU General Public License along
+ * with this program; if not, write to the Free Software Foundation, Inc.,
