I've got some code that looks like this on the file system:
1.java A/a.java The code in A is contained in a git repo.
However, I now want to expand the repo to cover the entire code base (i.e. including 1.java which is 1 directory up).
I've got a feeling (having played around with submodules) that it's not as easy as just init'ing a git repo in the parent directory. Am I right? If so, how should I tackle this?
