I'm very glad you've enjoyed my "exemplary" module. And I've also
figured out boost.build v1. Definitely not harder to figure out than
automake or even make. It's a very edifying way to build my little C++
example, too.

Version 0.5.2 now includes a Jamfile that builds the module.

shoutpy is a wrapper that lets you use Python to send compressed audio
to an icecast server for internet radio broadcast. The wrapper uses
three files: a header and C++ file to wrap libshout2 in a C++ class,
and the boost.python declarations in the third.

http://www.xiph.org/~brendan/shout-python/ wraps the same library
using the Python C api directly; my boost.python binary is 29 times
larger than that when compiled by distutils and the boost-jam debug
build is 165 times larger. When you run 'strip' on shoutpy.so the
extension is only 18 times larger than the C version of almost the
same thing. But as we know the boost.python wrapper gets written much
more quickly and in a less dodgy way than often ad-hoc
direct-to-Python-API code, and if we didn't care about programmer
efficiency we wouldn't be using Python in the first place.
