make a subdir called backup
copy all the current stfuff there
after working a while type

	for f in *.c
	do 
		diff $f backup/$f > diffs/$f
		if test -s diffs/$f
		then
			echo Changed $f
		else
			rm diffs/$f
		fi
	done

which will tell you the names of the files that are
changed and will leave in the diffs dir the diffs
only for files that are differnt
