[Zope] how to configure Zope to use Python 2.3.3

[Rod Thorburn]

I am running Zope 2.6.3 (binary release) on win2k, which by default installs
Python 2.1.3 . However, I wish to use Python 2.3.3 and I can't see how to
'swap' Python instances.

Apologies for the apparent naivety of this question. I am new Zope,
obviously.

Regards

Rod
