Some more factoids that may be of use:
1. The last Python you install will take over all the file
associations, start menu stuff, etc.
2. You can enumerate over the Pythons you have installed in \
3. If you silently install a Python PACKAGE made with distutils'
bdist_msi, it will by default install to the latest Python version it
finds (2.6 > 2.5 > 2.4 > 2.3)
