SubCommander

Well, I have been looking for a portable SVN client for a while. I know about RapidSVN portable, but that seems to have died. I really only needed it for this laptop (which I don't have admin on), and I found SubCommander. After looking at it, it seems to only save settings in my documents, and none in registry (that I could find). I figure it wouldn't be that hard to get this as a true portable app. It's open source as well (Under the GNU), so there should be no legal issues.
