Oh right, the Makefile build still exists. :-)

Your original thought--have make and CMake use the same scripts—was laudable, but we'd have to do something like rewrite this stuff in Python to make it both multi-platform and multi-build-tools compatible.  I don't have the Python chops for that, but if somebody else wants to do it, I'm happy to throw away my stuff.

I thought my CMake code would do the same.  Or should I not be looking for the text "origin"?  I was seeing that in my git repo, but I'm not exactly a sophisticated git user.  Maybe I should have that match any non-whitespace string?

I just saw this:

+    # FIXME: Extract URL from 'git remote -v'

But maybe I was looking at the wrong version of the patch. Regardless, I would do the same thing GetRepositoryPath does, which doesn't assume the name of the remote.

On a related note, Mark mentioned an issue using the git-svn code path when the current git branch isn't based on SVN, but I'll look into that later—no need to block this patch on it.

Thanks, Paul,
Jordan
