Send all applications the WM_DELETE_WINDOW event + 2. Pop up a dialog to ask the user to quit X-Window. + 3. If pressed ok, kill all applications. +- The command line options are ignored :-( + +The idea of this quick&dirty hack is, that the applications have a chance +to ask you somthing befor exit really.
