Uh, please don't use BCC to send to the list, it makes replying a tad

There was a method in the message you quoted:
-----
# Some config file
# $FreeBSD: blah$
# $MD5-Checksum: abcdefg8273912$
# Foo
a=1
b=2
-----
# (this is a Perl regexp, but it's possible with grep, somehow, I'm sure.
CHECKSUM=`grep -v \$MD5-Checksum(: [0-9a-fA-F]*)?\$$ | md5`
and it's easy enough to use sed to replace $MD5-Checksum$ lines with
CHECKSUM, and also compare the two...
CVS could even be setup to automagically insert the checksum, as it does
with the $FreeBSD$ lines currently.. (Doing so whilst observing the various
weird -ki flags to disable $$ expansions would be more difficult, however).
