Abstract
This demo presents MAKAO (Makefile Architecture Kernel featuring Aspect Orientation), a re(verse)-engineering framework for build systems. At its heart, MAKAO makes the build's dependency graph available in a tangible way. Aside from visualisation, this enables powerful querying of all build-related data, as well as various filtering techniques to define views on the build architecture. If desired, all this gathered information can be put to use to write aspects for refactoring the build. Afterwards, validation rules can help in assessing failure or success.
