Don't bother. I found a serious scalability issue in cvs2svn.py with
large repositories on Friday, and just haven't finished my analysis.
I'll post details on users@cvs2svn.tigris.org on Monday, but for now,
I'd suggest holding off on converting your repository.


PS The short explanation is that the anydbm db doesn't scale well to
hundreds of thousands of keys.
