This is right. But I was confused by the fact that the first-level items
in the list ("Twisted Conch Documentation", "Twisted Core Documentation",
etc.) link to pages that _again_ present links to the second-level items.
Adding to my confusion was the fact that the links on the main page have
different names from the ones on the subpages.

i don't know howto create an exe file using cx_freeze from .tac file.
is there a way to tell reactor to run application and services defined
so i can skip .tac file and just execute python file?
maybe something similar to this:
application = service.Application("Services")
factory1 = protocol.ServerFactory()
factory1.protocol = Protocol1
internet.TCPServer(8000, factory1).setServiceParent(application)
factory2 = protocol.ServerFactory()
factory2.protocol = Protocol2
internet.TCPServer(9000, factory2).setServiceParent(application)
# howto make reactor do something like this:
reactor.run(application)

Re: [Twisted-Python] Deferred documentation.
I haven't been following the thread, but just wanted to mention something that caught me out when I was learning to use deferreds. Both the old deferred documentation and your fix-up fail to mention addCallbacks() until near the end, when in practice I find addCallbacks() to be much more useful than addCallback(). The diagram near the top demonstrating the deferred process also implies the use of addCallbacks(), even though prior to this only addCallback() and addErrback() have been mentioned. This confused me into thinking a consecutive addCallback().addErrback() would register a callback and an errback at the same point in the processing chain. Apart from this point I found the old documentation very clear. If you really want the idiots guide I think you need animated diagrams, or something, but I don't see that happening.

Good catch, I really should mention that...

Sadly it's undocumented, but you're probably looking for:
http://twistedmatrix.com/documents/current/api/twisted.application.app.html#startApplication
The only examples I can find of it's use are by people who want to start a
"tac" type application as a WinNT Service, but I think it would work for
your purposes as well.
Here's an example:
http://foobar.lu/wp/2007/06/27/runnning-a-twisted-application-as-windows-service/
You can see the application object is created as normal (though in the
example it happens in a different file and is imported), then
startApplication is called, then reactor.run().
Good Luck!

It's not clear from your message whether you're using
internet.TCPServer() in your actual production code, or if that's just
something you picked to make a simple example for the mailing-list.
If you really are using internet.TCPServer(), you can just skip the
Application object entirely, and call reactor.listenTCP() instead of
internet.TCPServer(), then reactor.run() at the bottom.
If you've written your own Server or Application subclass that you want
to run, Kevin Horn's answer is probably the one you want.
