Selecting a different config.py

Happy Christmas everyone!

In the pyblosxom.cgi script there is:-

    # this allows for a config.py override
    script = os.environ.get('SCRIPT_FILENAME', None)
    if script is not None:
        script = script[0:script.rfind("/")]
        sys.path.insert(0, script)

Is this saying I can specify a different config.py (or a different
name for it) by setting SCRIPT_FILENAME?  If so, where do I set the
SCRIPT_FILENAME variable so that it gets picked up when the CGI is
run?
