Comment (by jinmei):

 I couple of points that may be helpful:

 - I suspect a straightforward implementation of this python wrapper
   would need to get access to symbols (and perhaps class/structure
   definitions also) defined in pydnspp.so, which would be very tricky
   (or may be mostly impossible if we want to be portable).  I
   encountered this issue for the DNS ACL wrapper, and my resolution at
   that time was to use an intermediate frontend written in Python that
   converts pydnspp objects to other Python native objects via
   serialization so that the C++ wrapper itself wouldn't have to use
   pydnspp definitions directly.  You may need to do the same thing (or
   may find a better solution).
 - I suggest considering the use of src/lib/util/python/pycppwrapper_util.h
   to avoid various pitfalls of the Python C API (see the doc in the
   file for more details).  The mkpywrapper script with the template
   C++ files may also be useful.
 - To generate pydoc in the C++ wrapper code, you may find the conversion
 script useful.  See my message on bind10-dev:
