[Numpy-discussion] how to reference Numerical Python in a scientific publication

[Sebastian Haase]

Hi,
we are using numerical python as an integral part of a microscope 
development project over last few years.

So far we have been using exclusively numarray but now I decided it's 
time to slowly but sure migrate to numpy.

What is the proper way to reference these packages ?

Thanks to everyone involved,
