This isn't answerable in short form comment thread like you would find here. Besides the structure of the repo itself, you have to consider the "base" SCM software, as well as the interfaces that are and can be built around it. You are probably limiting yourself to a specific implementation of git, and for that, a specific and relatively concise answer can probably be given. But the issue in general is much, much more expansive than that. The question as posed doesn't give us enough information to give a proper answer. As such, you can see how the answers so far are all over the board.
