Hi all,

While at EuroSciPy 2010 I've been chatting to Pauli Virtanen and David
Cournapeau about how NumPy etc are doing things - they have got a
working single code base written in Python 2.x which supports Python 3
via the 2to3 script, and plan to continue like this for the medium term.
For their C code, then the usual #ifdef tricks are used. See also:
