Yeah, git's stuff is nowhere even *near* python3 ready.

I have it on my to-do list to run 2to3 on the in-tree scripts as a diagnostic, but I haven't had time to do that yet...mainly because cvsps/cvsimport blew up in my face when I poked at them.

Now I need to go beat parsecvs into shape and run both it and cvs2git against the CVS torture tests I'm developing, so the 2to3 check won't happen for a week or two at least. Sorry.

As in a general thing, I wouldn't advise worrying too much about python3 compatibility. That version is not gaining adoption very fast, mainly due to the rat's nest around plain strings vs. UTF-8 which can make code conversion a serious pain in the ass.
