I agree about switching just after a release, but it's not ready for
primetime yet IMHO.

Firstly, I think most on this list are unaware just how hideously
difficult Boost2Git has become. Every time you think you're getting
closer to done, another new minefield of subtle issues appears which
causes more borkage across the whole conversion process. Dave and
Daniel absolutely deserve a huge round of applause for wrestling that
bull out of its china shop.

I would really *strongly* advocate a period where the SVN repo is
used for write only, but the git repos are used for everything except
writes. Boost2Git has been designed exactly to do that. We should
take advantage of it.

Such is the need for proper testing I would also expect such a test
period to last at least two Boost releases. More, if people want all
of sandbox working perfectly.

I also think this list's opinion on Boost2Git's readiness is
insignificant compared to Dave's and Daniel's. I only messed with the
conversion code for a short while, and I came away feeling awed.
