+README.SUSE for xtexit
+kfr@suse.de 7.5.96
+
+
+I changed the original program as follow:
+
+- Use the 3D Athena widgets (-lXaw3d instead of -lXaw in Makefile)
+- The program steps are:
+  1. 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. If you are in an editor you can
+choose to save your work. If there is nothing to ask, the programms
+quit immediatly.
