[Numpy-discussion] ANNOUNCE: ETS 3.2.0 Released

Hi -

thanks for all the good work on this!

I have been using an older version of the ETS, which I got when I installed
the EPD (4.0.30001) and now I have finally gotten around to trying to update
my ETS to this version.

I have a question - how do I go about uninstalling my previous version of
the ETS? A more general question to anyone - what's the right way of
uninstalling any old python package? In the past, I have been advised to go
in and run "rm -rf" on the directory inside my site-packages directory (and
remove stuff from "easy-install.pth"?), but in the case of ETS, I am not
even sure which directories in there belong to ETS.

Is there some elegant way of uninstalling python packages?

TIA --

Ariel
