    Sébastien> http://orgmode.org/manual/exports.html#exports

That option controls what is exported, but I really need to tangle:
there're portions of the file, section headings and other documentation
that don't belong into the output file. So for instance given:

* Introduction
  This is a file that does blah
* Configuration
#+tblname: config
|a | nice table|

*Details
#+srcname: procmail-rules(config=config)
#+begin_src emacs-lisp :exports results :results output :tangle ~/.procmailrc
 ... elisp code that evaluates to procmail rules  
#+end_src

Of this entire file, noting should end up in ~/.procmailrc except for the
result of the evaluation of procmail-rules, which is what I hoped to
achieve with ':tangle ~/.procmailrc' and ':exports results' combined.

Thanks,

        Maurizio
