The cksum(1) tools shipping with NetBSD 4 and -current have a `-c
<file>' option which does what you want.

You could start by reading the checksum file line by line:

	while read line; do
		# now `$line' is the next line read from $1
	done <$1

To parse the md5(1) output, note that everything between the first
opening backet '(' and the last closing bracket ')' is the filename,
and the last word of the line is the checksum.
