the easiest way is to split your CGI module in two parts; use the following
script as a wrapper, and place the program logic in a separate script ("my-
script.main()" in this case):

#!/usr/bin/env python

import cgi, StringIO, sys, traceback

try:
    import myscript
    myscript.main()
except:
    print "Content-Type:", "text/html"
    print
    file = StringIO.StringIO()
    traceback.print_exc(file=file)
    print "<pre>"
    print cgi.escape(file.getvalue())
    print "</pre>"
