I haven't had a hard look, but this reminds me of the Android build system. Was that an inspiration / have you had a look at it? It's quite nice. One issue I have with all build systems, Android's included, is the amount of magic that goes on -- variables defined in other files which are automatically in scope for your Make file, and, worse, variables you define being magically modified by something else. This is an issue for all Make-based systems because there are so many possible sources for variable definitions. Scons is also guilty of this. Any thoughts on reducing that issue?
