[pygame] Numeric/NumPy/Numarray Clarification

[Chris Ashurst <CAshurst@xxxxxxxx>]

I've been messing around with PyGame and the OpenGL bindings for a while
now, and I've recently begun to start seeing the light of using the array
classes from numpy for various math operation.

The thing is... Does anyone have any sort of clear idea about which package
I should have installed out of Numeric, NumPy and Numarray? They all seem to
be by the same bunch of people, but the fact that they all seem to do the
same thing, but are named differently and have no clues about them to let
you know which one does/has what bundled in with it.

For instance, in the pygame repository there's a little plasma demo that
uses RandomArray which is suppsedly in the Numeric package. I have the
Numeric package installed, but after searching through the
/usr/lib/python2.4/site-packages directory, I did not find RandomArray in
the Numeric package, but I *did* find a RandomArray2 module inside the
Numarray package. So in the code, I had to replace "from RandomArray import
*" to "from numarray.random_array.RandomArray2 import *".

Ultimately, that did the trick of solving the "missing" RandomArray import
problem, but seriously, I just want a nice, clean site-packages directory,
and just need some pointers on which bloody package I *should* have
installed, or at the very least, someone explain to me the differences
between the three apparently different packages.

Sorry for the long-windedness, but it's just kinda frustrating not knowing
if I have the "right" package installed.

Thanks :)
