6.13.  Control

   The Control-header marks the article as a control message, and
   specifies the desired actions (additional to the usual ones of
   storing and/or relaying the article).

      header              =/ Control-header
      Control-header      = "Control" ":" SP Control-content
                     *( ";" extension-parameter )
      Control-content     = [CFWS] control-message [CFWS]
      control-message     = <empty>

   However, the rule given above for control-message is incomplete.
   Further alternatives will be added incrementally as the various
   control-messages are introduced in section 7, or in extensions to
   this standard, using the "=/" notation defined in [RFC 2234].  For
   example, a typical CONTROL-message would be defined as follows:

      control-message     =/ CONTROL-message
      CONTROL-message     = "CONTROL" CONTROL-arguments
      CONTROL-arguments   = <the argument(s) specific to that
                   CONTROL-message>

   where "CONTROL" is a "verb" which is (and MUST be) of the syntactic
   form of a token and CONTROL-arguments MUST be of the syntactic form
   of a CFWS-separated list of values (which may require the use of
   quoted-strings if any tspecials or non-ASCII characters are
   involved).

   The verb indicates what action should be taken, and the argument(s)
   (if any) supply details. In some cases, the body of the article may
   also contain details.

   An article with a Control-header MUST NOT also have a Supersedes-
   header.

        NOTE: The presence of a Subject-header starting with the string
        "cmsg " and followed by a Control-message MUST NOT be construed,
        in the absence of a proper Control-header, as a request to
        perform that control action (as may have occurred in some legacy
        software). See also section 5.4.
