I've updated the description of the array interface (array protocol).
The web-page is
http://numeric.scipy.org/array_interface.html
Basically, the Python-side interface has been compressed to the single
attribute __array_interface__. There is still the __array_struct__
attribute which now has a descr member to the structure returned (but
the ARR_HAS_DESCR flag must be set or it must be ignored).
NumPy has been updated so that the old Python-side attributes are now
spelled:
__array_<somename>__ --> __array_interface__['<somename>']
