Python port information

There's highly experimental Python port of Boost.Build V2. It's currently not intended for users at all, and unless you're willing to develop it, we suggest you don't even look at it.

If you're willing to work on that port, follow these steps:

• Get CVS version of Boost.Build V2
• Run the following command from the source root:

  cvs up -r BOOST_BUILD_PYTHON python
  cvs up -r BOOST_BUILD_PYTHON pybb.jam
  

• Build bjam with Python support:

  ./build.sh --with-python=/usr
  

• Set the BOOST_BUILD_PATH to the directory where Boost.Build is located.

• Go to python/tests/bjam/make and run:

  bjam --build-system=pybb
  

The expected effect is that the a.cpp file is copied to a file.
