There are two ways:

1. Raise an exception derived from std::exception. It will be translated to
a Python exception (see handle_exception() in conversions.cpp).

2. Use the standard Python interface to set an exception, then throw
boost::python::error_already_set(). E.g.:

        const char message[] = "value out of range for Python int";
        PyErr_SetString(PyExc_ValueError, message);
        throw boost::python::error_already_set();

HTH,
Dave
