setend + xracer

[Bryan Cassidy]

I'm trying to set the environment variable $XRACER_HOME to
/usr/local/share/xracer and don't know how. In the handbook it says
setenv ??? /path/ so I tried bothsetenv $XRACER_HOME
/usr/local/share/xracer and setenv XRACER_HOME /usr/local/share/xracer
 and nothing works. Guess I don't get how to set an environment
variable. Some quick help? Wouldn't mind checkin this game out with
the Nvidia drivers I have installed.
