6.11.  Control

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

      Control-content     = CONTROL-verb CONTROL-argument
      CONTROL-verb        = <the verb defined in this standard
                     (or an extension of it) for a specific
                     CONTROL message>
      verb                = token
      CONTROL-arguments   = <the argument defined in this standard
                     (or an extension of it) for a specific
                     CONTROL message>
      arguments           = *( CFWS value )  ; see 4.1
[Observe that <value> reqires the use of a quoted-string if any
tspecials or NON-ASCII characters are involved. This is a restriction on
present usage, but follows Mime practice.]

   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. Section 7 describes all of the standard verbs.

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

        NOTE: The presence of a Subject header starting with the string
        "cmsg " and followed by a Control-content 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.

-     NOTE:  Control  messages  are  often processed and
-     filed rather differently than normal articles.
-
-     NOTE: The restriction of verbs to letters and dig-
-     its  is new, but is consistent with existing prac-
-     tice and potentially simplifies implementation  by
-     avoiding  characters significant to command inter-
-     preters.  Beware that the arguments are  under  no
-     such restriction in general.

-     NOTE:  Two  other  conventions  for distinguishing
-     control messages from normal  articles  were  for-
-     merly  in  use:  a  three-component newsgroup name
-     ending in  ".ctl"  or  a  subject  beginning  with
-     "cmsg "  was  considered to imply that the article
-     was a  control  message.   These  conventions  are
