Subject: [PATCH]         The enclosed patch fixes the Makefile contained in
 share/doc/usd/{30.rogue,31.trek}: make fails if the games source tree is not
 present (see the mail that I have sent yesterday).

        This patch makes the Makefiles test if the games source
tree is present.  If it is not present, the Makefiles default to
no operation.
