JW-Build is small. You can install the package with your distribution's package
manager, but you can also keep it within your version system, alongside your
own code. It's also meant to be the lightest possible touch on any given source
code package, in terms of needed prerequisites, and also in terms of code you
need to put into those packages. This way, it's easily introduced - but it
also allows you to easily opt out of JW-Build at any time.

makefile generation as done by CMake or GNU Autotools, to keep the running code
small and readable to facilitate debugging. To achieve this, it has to detect a
couple of things in every directory, but there's a caching mechanism in place,
which keeps builds reasonably fast.

JW-Build is designed to be friendly to both developers and integrators. You can
cd into any given directory, run make, and expect the resulting code to work
and be testable. It has built-in support for remote Git repositories and
collaboration. Of course, it can build and package itself.
