Which may or may not be a bad thing. The problem I see here is: How do we seperate the submodule from the superproject? Without the history (commits and trees) of the superproject the submodule trees do not make sense anymore. The reason users have submodules is because the projects are seperate somehow. With just trees in the submodule it becomes tied quite tightly to the superproject, IMO. One step further: Why use gitlinks to point to trees? Let's just use normal tree links instead, we already have that implemented :) Cheers Heiko
