+# KXMLGUI
+
+Framework for managing menu and toolbar actions
+
+## Introduction
+
+KXMLGUI provides a framework for managing menu and toolbar actions in an
+abstract way. The actions are configured through a XML description and hooks
+in the application code. The framework supports merging of multiple
+description for example for integrating actions from plugins.
+
+## Kiosk
+
+KXMLGui makes use of the Kiosk authorization functionality of KConfig (see the
+KAuthorized namespace in that framework).  Notably, QAction instances added to a
+KActionCollection are disabled if KAuthorized::authorizeAction() reports that
+they are not authorized.  The items on the standard help menu (KHelpMenu) can
+likewise be disabled based on Kiosk settings, and toolbar editing can be
+restricted.
+
+See KActionCollection, KHelpMenu and KToolBar documentation for more
+information.
