I was thinking of just 'cksum bin.*' since I would *assume* that
the cksums, once correct, would indicate a "good" file...

how about:
	cksum *.* > fudge
	comp fudge goodsums.lst
but, of course, that would require the user to have *all* the
files listed in "goodsums.lst" online.  Also, you'd have to create
an entry for goodsums.lst in the goodsums.lst file itself!  And,
since DOS will create fudge before completely expanding the *.*
in the cksum command, you need to take it into consideration, also.
