Yes. And there's no windows-specific interface to Subversion, other
than those produced by parties other than the Subversion developers.
That's all I menat.

Except that it's the reference UI, and it's produced by the subversion

I never had a bad experience with them. I use SVN and CVS "GUI" tools
from within emacs; they're very useful. In fact, I love them. That
said, I have a decent grounding in how the tools work because I read
the official documentation and familiarized myself with the interfaces
it describes. I want other Boost developers to have the same
grounding, for their own sakes, and for mine (so the repo doesn't get
messed up).
