At present, boost.python provides an 'array' type that corresponds to 
Python's numpy.ndarray.
However, the wrapper isn't rich enough for example to pass raw data 
pointers, making it not suitable for some applications.

Docs for the existing facilities can be found at 
http://www.boost.org/doc/libs/1_41_0/libs/python/doc/v2/numeric.html.

We have had a couple of discussions about improving boost.python's 
support for numpy, but nothing materialized yet. May be we should rally 
up enough momentum to get this done.



Thanks,
         Stefan
