> For example, one advantage of git submodules over git subrepo is that it allows much smaller repositories. Since subtrac copies the commits into the parent repo, it doesn't have that advantage. I don't think there would be a size benefit regardless, since you would still be cloning the submodule from somewhere. There are good reasons why you would want the contents of a submodule to remain a submodule. If you have a documentation wiki, or some sort of helper program, or a data repo, you would probably be better having it be a submodule. But submodules are awkward for a variety of reasons.
