The 13 tcsh users probably specifically requested tcsh or they would have
ended up with csh by default, so here are some more stats for you...
(44-15)/115=0.25 or 25%, so my number was actually 35/28=1.52 or 52% over
stated. The original 10% was still 250% understated. I'll take stats 52%
in error over 250%, or 2.5/0.52=4.8 times more accurate any day.
:-) :-) :-) (I can use and abuse them just as good as the next guy...
unless he happens to be the author of the book by the similiar name...).
