[Numpy-discussion] New array interface helper file

At http://numeric.scipy.org/array_interface.py you will find the start of a set of helper functions for the array interface that can make it more easy to deal with. It also documents the array interface with docstrings. I tried to attach these to properties, but then I don't know how to "see" them from Python. This is the kind of thing I think should go into Python If anybody would like to try their hand at converter functions to go back and forth between the struct module strings and the __array_descr__ string, make my day. -Travis
