Subject: Greatly expand documentation comment at head of file... I had to  try
 to understand it; maybe this will help someone else do so too. Default
 CVSRootDir to $CVSROOT first, then the path in ~vadve only if $CVSROOT  was
 not set. Checkout with -z3 if we might be checking out over ssh/rsh. Check
 the filename of gnuplot to see if it is executable; if not, as a  last
 resort, try just plain "gnuplot", hoping it is in the path somewhere. Remove
 a little extra whitespace.
