Access to Git Repos within PHP

I haven't noticed this question asked before, so I'll ask it. Is there a "fully-baked" solution for using git to manage, say, blog posts and manage the whole thing via PHP? Seems to me like you could use git to fetch and store datestamped and incremental blog posts. And thus, one could build a blog infrastruction around this. Problem is, what if the hosting company doesn't provide the git program on its servers, or it doesn't allow running external git commands via a shell? The solution would be some sort of "module" written in PHP which would allow access to git objects, both the fetching, creation and updating of them. The question then becomes, is there any PHP-based solution to doing this, which is "fully-baked", as in, not half-built and then abandoned? Paul -- Paul M.
