Fixed, thanks for the heads-up. I reworked the docs significantly,
they're here:

And they reference new a new git mirror that is up here:

Which should make the whole process quite a bit easier for the beginner.

It's easy to just get the code out,

   git checkout other_branch tools/build/v2

but that checkout isn't tracked. What's the use case? It is easy
enough to just create a branch, put your new stuff on it (if it happens
to be isolated to one subdirectory, fine) and push it. There are a
couple of goodies out there like submodules and the subtree merge
strategy that I have yet to play with, maybe these are relevant.

Git-svn isn't very good at tracking our haphazard organization of
branches and tags. That build/python_port branch is worthless.

If you want to start working on the python port in gitland while
tracking the svn trunk, see those new docs, most of it is one big
example of how to do this. In short, you'd:

- make a gitorious account and your own boost repo clone
- clone your clone down to your local machine
- make two local branches, one for private development (and rebasing),
one for pushing
- svn export your current python port stuff into the git repository and
- follow the instructions for fetching, rebasing and pushing as new
commits come in to trunk

Well it is my preferred place for experimentation, certainly, and I know
I'm not alone. I'm reluctant to do any 'envisioning' at this point. :)
  I guess we have to wait and see.
