+ *
+ * Each KXMLGUIClient represents a part of the GUI, composed from containers and
+ * actions. KXMLGUIFactory takes care of building (with the help of a KXMLGUIBuilder)
+ * and merging the GUI from an unlimited number of clients.
+ *
+ * Each client provides XML through a QDomDocument and actions through a
+ * KActionCollection . The XML document contains the rules for how to merge the
+ * GUI.
+ *
+ * KXMLGUIFactory processes the DOM tree provided by a client and plugs in the client's actions,
+ * according to the XML and the merging rules of previously inserted clients. Container widgets
+ * are built via a KXMLGUIBuilder , which has to be provided with the KXMLGUIFactory constructor.
