Upgrade Python 2.6.4 to 2.6.5

[python at bdurham.com]

Martin,

If we install over an existing version of Python 2.6.5, will our PTH
files and site-packages be preserved?

Or do we need to back out our 3rd party packages, install Python 2.6.5
and then manually restore our 3rd party packages?

Thank you,
Malcolm
