The history on the GIT tree is really not interesting - it just shows when

Yes - that would be best. THe original code is nice for debugging behavior

If anything, we can toss the original tarball for archival purposes.

Absolutely, I'm interested. Also, we will want to teach buildrom to build
the GNUified VSA.
