Can anyone tell me how I find which jamfile is run when the line:

<library>boost/python/boost_python

is encountered by bjam?

I don't think this is quite correct, but anyway, the project /boost/python corresponds to the Jamfile in libs/python/build/. There are a bunch of calls to use-project in Jamroot to set this up.

And are there equivalent 'shortcuts' to other boost libraries, particularly boost unit test framework?

Yes. Actually there's a shorter form. Jamroot defines aliases for all the libraries like /boost//unit_test_framework In Christ, Steven Watanabe
