 I followed the tutorial about embedding at
 http://www.boost.org/libs/python/doc/tutorial/doc/html/python/embedding.html#python.using_the_interpreter

 but I am now faced with some errors (VC++ 6.0, latest
 Service Pack running on Windows 2000 SP4).

 The errors:

 Compiling...
 StdAfx.cpp

 pytest.exe - 9 error(s), 0 warning(s)

 handle<> ignored((PyRun_String(

 Dirk, if you would check this out and see if you think there's still
 something to address, I'd be very grateful.
