Confix is a build tool for source code packages, on top of GNU
Automake. It inspects the package's source code, tracks inter package
dependencies, propagates checks across package boundaries, and finally
writes Automake input files for the maintainer.
Both forward-chaining and backward-chaining rules (which may include pythoncode) are compiled into python. Can also automatically assemble python programs out of python functions which are attached to backward-chaining rules. See pyke.sourceforge.ne
