I'm raising this issue again. I did some digging and found an Open-Bio
mailing list thread from 2006 that states:

The full thread is available from <http://tinyurl.com/2oh9x4>.

Considering that Subversion addresses the weaknesses of CVS, I'm
surprised that every Open-Bio project still runs from CVS instead of
Subversion. Someone's got to lead the way, why not have it be

We've had a lot of active development as of late, with SeqIO, and now
with NumPy transitioning. Either of those cases would have been better
tracked through Subversion, which keeps tallies of revisions on a
repository-wide basis, rather than a file-by-file basis.

I've also found that researchers new to revision control have had
great success in picking up and using Subversion in our local Software
Carpentry group. I have also created a screencast on using Subversion
which demonstrates all the basic commands and activities. This
screencast is available in AVI (MPEG4) and OGG formats at

I hope the BioPython developers will consider a move to Subversion
seriously. If there is support from the devs, but no interest on
anyone's part to make it happen, given the proper people to contact, I
will be happy to get this moving as a way of contributing back to the
BioPython community.
