XREPLIC ggg:nnn[,ggg:nnn...]

    The XREPLIC command makes is possible to exactly duplicate
    the news spool structure of one server in another server. It
    first appeared in INN.

    This command works similarly to the IHAVE command as
    specified in RFC977. The same response codes are used. The
    command line arguments consist of entries separated by a
    single comma. Each entry consists of a news group name, a
    colon, and an article number. If the server responds with
    a 335 response, the article should be filed in the news
    group(s) and article number(s) specified in the XREPLIC
    command line.  If the server cannot do successfully install

    the article once it has accepted it, a 436 or 437 response
    code can be used to indicate the failure.

    This command should only be used when the receiving server
    is being fed by only one other server. It is likely that
    when used with servers that have multiple feeds that this
    command will frequently fail.

    XREPLIC slaving has been deprecated in INN version 1.7.2 and later.
    INN now has the ability to slave servers via transparent means, simply
    by having the article's Xref header transferred. (In previous versions,
    this header was generated locally and stripped off on outgoing feeds.)
    It is likely that future versions of INN will no longer support
    XREPLIC.
