I think the second option is definitely simpler, but doesn't make it
easy to obtain a particular version of a file... We could support using
git-archive, tho this does require a new version of git (1.7.9.5)

That might be more work than necessary though.. I just don't like that
the 2nd method requires ensuring that the tree is already at the correct
version.. It's not a huge burden though.

Thanks,
