Issues to be tackled in this repo:
-- Better output of submodule diffs (in progress)
+- Better output of submodule diffs (I expect full support in git 1.6.6. Patches are already in Junio’s master, only one patch accepted by Paul in master of his gitk repo has still to be merged into Junio's repo)
- Adding tools to git gui and gitk for easier submodule handling (in progress)
- Collecting hooks useful for submodules
- Better support for merging and resolving merge conflicts of submodules
