[Tutor] Upgrading 2.2 to 2.3

[R. Alan Monroe]

I can't find any info on upgrading on python.org. Am I supposed to:

a) put 2.3 over 2.2 in the same folder?
b) uninstall 2.2 then install 2.3?
c) install 2.3 in a new folder (what happens to all my old
site-packages?) ?
d) something I hadn't thought of?

This is on Windows 2000 FWIW.
