You'd write a .tac file and run it with "twistd -y [tac file]".

The documentation is at
http://twistedmatrix.com/documents/current/howto/application but is
terse and desperately short on examples.

Several of the examples use that setup:

http://twistedmatrix.com/documents/current/examples/chatserver.py
http://twistedmatrix.com/documents/current/examples/emailserver.py

At the end of the tutorial intro, the finger code is converted to a tac
file too:
http://twistedmatrix.com/documents/current/howto/tutorial/intro

The crucial step is creating the object called 'application' at the
global level -- this is what twistd seeks.
