Tools to statistically analyze a repository

[genkuro]

Do tools exist which will pull statistics from a cvs repository?
Statistics = number of files, newest modified stamp, oldest modified
stamp, average modified stamp, and so forth per directory.

I'm looking for a way to tell which directories in a repository are
being actively coded.  I'm working with an unknown repository and I'd
sooner skip stale files.  A tool which churns out data similar to du
would be just dandy.

Many thanks.
