[GSoC 11] submodule improvements

Hi, I've been chosen to improve git submodules during the summer. My main focus will be to move the .git-directory away from the submodules so that submodules can be deleted and created in the working tree [1].

I will post updates on this list labeled [GSoC 11 submodule] for those interested in following my work. I've also put up a fork of Junios repo on github, where you can find my [2] branches.

My name is Fredrik Gustafsson, I study electronics with a software path in Lund, Sweden.

My schedule is a bit strange because of the Swedish semesters, so my work will begin tomorrow (Monday).

I'm looking forward to work with my mentors (whose already been very supportive) and the rest of the git community.

The proposal says

    The submodule system is widely used, specially within the android
    platform.

which puzzles me somewhat. The Android platform uses the Repo tool to help out with multiple gits in the same source tree, and Repo currently isn't based on submodules. Work is however ongoing to switch Repo into using submodules instead (which would make the whole tool rather redundant). Are you thinking of that work, or is there a misunderstanding somewhere?

That senctence can certainly be misinterpret, specially without the sentence after.

With "the submodule system" I didn't meant the git implementation of submodules but rather the use of multiple git-repositories connected in some way.

The git submodule-commands is one way to achieve this, there's many others, for example (part of) repo.

My goal is that the git submodule system should be good enough to be the only submodule system needed to be used with git.

I'm sorry for being unclear in the proposal.
