+/**
+ * Easy updating of menu accels when changing a KAccel object. 
+ *
+ * Since a KAccel object does not keep track of menu items to which it
+ * is connected, we normally have to manually call 
+ * KAccel::changeMenuAccel() again for each update of the KAccel object.
+ *
+ * With KAccelMenuWatch you provide the kaccel object and the menu
+ * items to which it connects, and if you update the kaccel you just have
+ * to call KAccelMenuWatch::updateMenus() and the menu items will be updated.
+ *
+ * It is safe to delete menus that have connections handled by this class.
+ * On deletion of a menu, all associated accelerators will be deleted.
+ *
+ * Note that you _have_ to call KAccelMenuWatch::updateMenus() after you
+ * connect the * accelerators, as they are not activated till then.
