Refactoring

Not ready to merge yet, need to load the results of the dependency analysis back into the Makefile (ie. need to add a bunch of `-include` at the end of the Makefile). I'll do that tomorrow.

Next: add more examples to check that the Makefile generation is ok, deal with the release scripts, and start porting my project.
I need to run the manual on dynlink, I always forgot how it works exactly. What type do you suggest?
