What's the advantage in writing a new build tool? I'm asking this because I'm doing the same using scons:
https://bitbucket.org/cavallo71/fatpython At the moment I'm very interested into this problem: the main advantages I see so far are (in scons) are node dependencies and the fact it is plain python syntax.
