Thanks. That's useful as a first pass.

I assume, though, that this approach understates the number of developers
involved because some changes are "funneled" through point people?  As a
simple example, patches might be submitted to various distributions and
then committed upstream--in this case the distribution person (rather
than the original submitter) is credited in the bitkeeper changelog,
