I anxious to try scipy core, but I don't want my system to stop working, 
either.  So let's see if I understand:

Current:   WinXP,   python 2.3

I would:
- upgrade to python 2.4
- rename the four files above (to save them, just in case ?)
- install scipy core
- make the necessary changes to my sources

Third-party apps that depend on scipy, and whose sources have not been 
updated, will break.

Numeric and numarray won't be touched, so apps that use only them (and 
no scipy)  won't know the difference (VPython in particular)

Anyone know if matplotlib would break?   (I've asked on that list, too.)

Anyone know which, if any, apps would break?  (Mayavi,  etc ?)
