Hi Mike,

Since the MESA SDK requires adding lines to a user's .tcshrc file, what is
the best option for users of fri@ix? I would like to upgrade my version of
MESA within fri/sam to incorporate the SDK install, as it is now Bill's
default for testing, but I don't want to mess up settings for other users
of fri. What do you recommend?

Thanks
