+  * The base class for KDirStat application windows. It sets up the main window
+  * and reads the config file as well as providing a menubar, toolbar and
+  * statusbar. An instance of KDirStatView creates your center view, which is
+  * connected to the window's Doc object.  KDirStatApp reimplements the methods
+  * that KMainWindow provides for main window handling and supports full
+  * session management as well as using KActions.
