I would like to have something better, no so much of a work-around.

Maybe I could hack something, are there some docs explaining the internal format of git objects? or, where to look in the source to find this info?

Another point, the application is written in Python, right now I have to open a shell to run the git commands.

It would be nice if the core functionality was implemented in a C library, then with a Python wrapper I could use git without going through the shell.

Is this something to be expected? There will be a "libgit" sometime in the future?

Probably I will have to hack something else to have ACID transactions, in the short-term. But "git" is at least interesting, since it could open a world of possibilities. If I ever have something to show, I will tell you.
