That might be interesting, but in SVN I don't know how to do the
equivalent of Git local commits with occasional pushes to a public
remote. I've been using that development model on other projects and
have come to like it so much I've lost interest in SVN.

I assumed, perhaps incorrectly, that since the boost/filesystem
headers are replace with a symlink, that would cause trouble with SVN.

Again, that's really a different experiment. Its basically simulating
a distributed development environment with svn. The equivalent of "git
push" is simulated with merge scripts. But I'm just not interested in
trying to hang onto svn. I've come to like git much better. It gets in
my way less often than svn.
