scriptName is the initial portion of the URL path that "belongs"
to your application. It is used to determine PATH_INFO (which doesn't
seem to be passed in). An empty scriptName means your application
is mounted at the root of your virtual host.
environ, which must be a dictionary, can contain any additional
environment variables you want to pass to your application.
bindAddress is the address to bind to, which must be a tuple of
length 2. The first element is a string, which is the host name
or IPv4 address of a local interface. The 2nd element is the port
number.
allowedServers must be None or a list of strings representing the
IPv4 addresses of servers allowed to connect. None means accept
connections from anywhere.
loggingLevel sets the logging level of the module-level logger.

this if you wanted to run your application as an 'external' FastCGI
app. (i.e. the webserver would no longer be responsible for starting
your app) If a string, it will be interpreted as a filename and a UNIX
socket will be opened. If a tuple, the first element, a string,
