Yes, in a sense everything is a wrapper for something. :)

In my example I should have written 

    run(application)

instead of 

    run(...)

Then the difference would be more apparent. Namely, in my 'wrapper'
it is explicit what application will be run and where all the services
came from, your 'wrapper' is just a customized version of twistd and 
what will be run depends on the command line and what will be found 
in the file system. In some cases I'd like to _explicitly_ code into 
main script what functionality my application provides and I do not
want twistd search file system for plugins at all.

I couldn't figure out how to use it without plugins. Obviously I'm 
missing something simple here. If you could extend your example to 
show how to use twistd functionality without writing plugins then it
would be just great.

Yes, that is probably why it is called twisted :)
