Thin and simple sounds very good. Let's try it with an example. Lets say we have one apllication App1 and three librarys (Lib1, Lib2, Lib3) with the following dependency-graph:

        App1
          /\
         /  \
   Lib1   Lib2
       \     /
        \   /
        Lib3 (don't really needed for this example but looks nice)

All components can be used individually and have their own upstream, maintainer etc.

To compile App1 however, I need some files from both Lib1 and Lib2 specifying it's API. To satisfy these dependencies, It sounds reasonable to link Lib2 and Lib3 submodules from App1. In your concept, can I construct a modules file to fetch the API files and
