XINDEX ggg

    The XINDEX command is used to retrieve an index file in
    the format of originally created for use by the TIN[6] news
    reader.

    The required parameter ggg is the name of the news group
    to be selected (e.g. "news.software.b").  A list of valid
    news groups may be obtained from the LIST command.

    The successful selection response will return index file
    in the format used by the TIN news reader followed by a
    period on a line by itself.

    When a valid group is selected by means of this command,
    the internally maintained "current article pointer" is set
    to the first article in the group.  If an invalid group is
    specified, the previously selected group and article remain
    selected.  If an empty news group is selected, the "current
    article pointer" is in an indeterminate state and should
    not be used.

    Note that the name of the news group is not case-dependent.
    It must otherwise match a news group obtained from the LIST
    command or an error will result.

    The format of the tin-style index file is discussed in the
    documentation for the TIN newsreader. Since more recent
    versions of TIN support the news overview (NOV) format, it
    is recommended that this extension become historic and no
    longer be used in current servers or future implementations.
