-
-   -  create a procedure `screenhack(dpy, window)'
-
-   -  create a variable `char *progclass' which names this program's
-      resource class.
-
-   -  create a variable `char defaults []' for the default resources, and
-      null-terminate it.
-
-   -  create a variable `XrmOptionDescRec options[]' for the command-line,
