It looks like this line:

  link media="screen" href="http://python.org/styles/screen-switcher-
default.css" type="text/css" id="screen-switcher-stylesheet" 
rel="stylesheet" />

was present in the first checkin by Stefan. I don't know what it was 
supposed to do.

Stefan if you are still around, can you comment on why this link 
exists? The target no longer exists.

Bern, I plan on deleting the line in a week if Stefan doesn't have any 
info. So the line should either be deleted or fixed.
