It's not, after all; what it does is pretty simple and can be done by
Boost.Build directly.

Uhm, not so fast. If you want to build anything like python modules,
which are shared libraries that link back to symbols in the
executable, you WILL need to follow the procedure executed by the
script.

They're non-trivial, for sure.

Sure. We could try it with your changes, but I bet it would break
Boost.Python. Any chance I can convince you to install Python and try
building the Boost.Python tests? If they work, I'll be happy to
accept your patch.
