describing the intended use of the newsgroup.

    If the second argument is present and it is the keyword moderated,
    the group should be created moderated instead of the default of
    unmoderated.  The newgroup message should be ignored unless there is
    an "Approved" line in the same message header.

3.4.  Rmgroup

                            rmgroup 

    This message removes a newsgroup with the given name.  Since the
    newsgroup is removed from every host on the network, this command
    should be used carefully by a responsible administrator.  The
    rmgroup message should be ignored unless there is an "Approved:"
    line in the same message header.

3.5.  Sendsys
                           sendsys (no arguments)

    The sys file, listing all neighbors and the newsgroups to be sent to
    each neighbor, will be mailed to the author of the control message
    ("Reply-To", if present, otherwise "From").  This information is
    considered public information, and it is a requirement of membership
    in USENET that this information be provided on request, either
    automatically in response to this control message, or manually, by
    mailing the requested information to the author of the message.
    This information is used to keep the map of USENET up to date, and
    to determine where netnews is sent.

    The format of the file mailed back to the author should be the same
    as that of the sys file.  This format has one line per neighboring
    host (plus one line for the local host), containing four colon
    separated fields.  The first field has the host name of the
    neighbor, the second field has a newsgroup pattern describing the
    newsgroups sent to the neighbor.  The third and fourth fields are
    not defined by this standard.  The sys file is not the same as the
    UUCP L.sys file.  A sample response is:

      From: cbosgd!mark  (Mark Horton)
      Date: Sun, 27 Mar 83 20:39:37 -0500
      Subject: response to your sendsys request

3.6.  Version

                           version (no arguments)

    The name and version of the software running on the local system is
    to be mailed back to the author of the message ("Reply-to" if
    present, otherwise "From").

3.7.  Checkgroups




 
RFC 1036              Standard for USENET Messages         December 1987


    The message body is a list of "official" newsgroups and their
    description, one group per line.  They are compared against the list
    of active newsgroups on the current host.  The names of any obsolete
    or new newsgroups are mailed to the user "usenet" and descriptions
    of the new newsgroups are added to the help file used when posting
    news.
