The "<?" stuff isn't part of core Python, hence your not being able to find
references to it on python.org. It's almost certainly part of a templating
system. Problem is, there are a great many of these for Python - see
<http://www.python.org/cgi-bin/moinmoin/WebProgramming> for many (though
probably not all) of them.
