Worse, it's a csh script which sources ~/.cshrc!! At least it did the 
last time I used csh seriously which was a long time ago. This can 
lead to mysterious, not to mention wrong, results because "which foo" 
will read .cshrc, change path accordingly, and tell you it found foo 
in location A. You will then go ahead and use $(shell foo ...) and 
/bin/sh will proceed to find foo in location B or not at all. Some 
systems have replaced it with a fixed, non-csh-specific version but not all.
