-Acknowledgment headers
-======================
-
-Messages that flow through the global pipeline get their headers 'cooked',
-which basically means that their headers go through several mostly unrelated
-transformations.  Some headers get added, others get changed.  Some of these
-changes depend on mailing list settings and others depend on how the message
-is getting sent through the system.  We'll take things one-by-one.
-
-    >>> from mailman.pipeline.cook_headers import process
-    >>> mlist = config.db.list_manager.create(u'_xtest@example.com')
-    >>> mlist.subject_prefix = u''
-
-When the message's metadata has a 'noack' key set, an 'X-Ack: no' header is
-added.
-
-    >>> msg = message_from_string("""\
-    ... From: aperson@example.com
-    ...
-    ... A message of great import.
-    ... """)
-    >>> process(mlist, msg, dict(noack=True))
-    >>> print msg.as_string()
-    From: aperson@example.com
-    X-Ack: no
-    ...
-
-Any existing X-Ack header in the original message is removed.
-
-    >>> msg = message_from_string("""\
-    ... X-Ack: yes
-    ... From: aperson@example.com
-    ...
-    ... A message of great import.
-    ... """)
-    >>> process(mlist, msg, dict(noack=True))
-    >>> print msg.as_string()
-    From: aperson@example.com
-    X-Ack: no
