Naff.

I just checked in a "cvs2git.c" file in the "tools" project (which has my patch application stuff).

It's still buggy, and it's hacky as hell, but you can basically do something like this:

	cvsps | cvs2git > script

with the normal setup for "cvsps", and "cvs2git" needs one additional stage, namely it wants to know the RCSDIR where to find the RCS files (that should be basically "$CVSROOT/module").

That _script_ then creates a git archive. Very hacky. So after you've successfully created the conversion script, check it to see that it looks sane, and then do

	sh script

and the end result is a git'ified version of your CVS repo (and a corrupted working directory, btw, so look out. It _shouldn't_ corrupt your old CVS repo, though, so it should be ok).

It has the logic for branches, but it doesn't work, and I'm fed up enough with CVS and RCS for the moment that I'm not going to work on it any more tonight. I don't know what stupid bug I have (I've had about a million of them on this silly program), but it's at a point where I think others might find it interesting, and it's probably/hopefully some really embarrassing typo or something and easily fixed.

It converted Peter's "syslinux" repository in a couple of minutes, resulting in 1038 commits (it _should_ have resulted in 1046 commits, that's the branch thing afaik) and most of it looks sane:

	    Initial revision

And btw, it's definitely cvsps that does all the heavy lifting here. "cvs2git" itself is 255 lines of horrid crud, and should have been written in perl, except I only do C..
