And the best part about waf? The explicit design intent that you include the build system with the source code. This gets rid of all the problems with build systems becoming backwards/forwards incompatible, and trying to deal with the issues when a developer works on one project using build system v3.9 and another that users build system v4.6 With waf, the build system is trivially included in the source, and so your project always uses the right version of waf for itself.
