Performing a compare between a set of files as of today and yesterday

[sduncan000]

I would like to determine all the differences that occur to a
particular folder structure within the respository (say, /cvs/foo/*)
between 2 weeks ago and today.

What is the easiest way to perform this compare?

I dont necessarily have tags applied to the files at those given
points in time either.

I had thought to perform an export using -D "2 weeks ago" and another
of the HEAD of the branch/trunk and comparing those outside of CVS,
but 1-is this a valid method, and 2-is there a better, more efficient
method?

thanks,
Steve
