[Zope] off topic: How do I run a python cgi?

Sorry for the off-topic-ness, but can anyone tell me "exactly" what I have to do to get a python script cgi working under IIS? Or point me at a web page? when I request http://mysite/test.py I just get the contents of the file back...ala print "Content-type: text/html" print print "<h1>Why doesn't this work?</h1>" thanks tom
