Up to this point there is no need to use the C API directly. Assuming you
have exported your C++ type 'Type' to python, you can write (inside C++):

namespace bpl = boost::python;
bpl::object instance(Type(...));

bpl::dict global;
global["instance"] = instance;
bpl::exec_file(python_script, global, global);


and the executed script can access your Type instance directly through
the 'instance' variable.

Caution: the 'exec_file' function has been added after 1.33.1, so
you need to use a CVS snapshot.
