Any interest in using c2.py as your test runner?

This is a CMake-based b2 replacement. It's basically b2 but works with CMake and supports a lot more stuff. It's basically a complete version of the multi-config stuff from CMake + Ninja but with more multiple compilers at the same time.

Let me know if you think it'd be cool to try it for the Beman Project, which is very Boost-y in nature.
