	I think I tried something like your second example last night.
	I think I did

	% cksum foodir/*

	and had to compare each file from another file I was copying from.
	it was tiresome to check each of dozens of files tho. I was here at 
	desk for something obscene -- over 12 hrs. getting my new [slightly
	used:)] computer back to normal.  

	if there isn't anything that can compare entire dirs, it looks like
	it's time to hack a small program.  tx, polyt.
