-                                BOILERPLATE
-
-   To get started with mixed model programming with Motif and OpenGL, this
-   boilerplate `application' might help get you started.
-
-   This program honors two environment variables:
-
-      SETVISUAL <id>    Makes the application use the indicated visual,
-                        instead of the one chosen by glxChooseVisual.
-
-      SAMEVISUAL        Make the application use the same visual for the
-                        GUI as for the 3D GL Widget.
-
-   The basic idea is to minimize colormap `flash' on systems with only one
-   hardware colormap, especially when focus shifts between several
-   of the application's windows, e.g. the about box.
-
-   If you have suggestions for improvements, please mail to:
-
-
-      Jeroen van der Zijp  <jvz@cyberia.cfdrc.com>
-
-
-   Feel free to turn this into a useful program!!
