You don't know from the start what will the tree look like. Git is well suited for your tree and will eat it with out solt Do not use subprojects these are used with two separately developed projects that are dependent (one on the other not two ways). For example I have a GUI app that uses wxWidgets. Instead of instructing my users on where to get it and what exact version to use, with what version of my program, I mirror it in a submodule and this is all done automatically for me and my cloners. What you need is topic branches. Not all branches need have all the same files. In fact they can have nothing in common. The only thing with git is that at a certain checkout in time only these files will be present on disk. So lets say you have: /include/lib4foobar /include/lib4bar /src/lib4foobar /src/lib4bar /src/foo /src/bar Lets complicate it and say lib4bar is also dependent on lib4foobar then you have these branches: lib4foobar lib4bar foo bar When you work on a library/app you take your foo-maintainer hat and push patches to your subtree branch. When it is time for integration, checkout master and merge all the branches in. Simple as hell. And faster then you ever imagine. Additionally you can have working branches that, lets say did-of-the-day, where you save work to 3 topics /src/bar /src/lib4bar /src/lib4foobar. Once you are happy. You can push them through the project branches, and delete the working branch, or you can merge that directly into master and when you pull master into the topic branches after a big merge, they will have it automatically. This is all very similar to Linux. With the subject maintainers and all, just with fewer people. PS: Don't forget to have a very first patch with nothing but a common root file like GPLv2 or README. The first patch is hard to work with.
