    1.30 + *   XPAT header range|<message-id> pat [pat...]
    1.31 + *
    1.32 + *   The XPAT command is used to retrieve specific headers from
    1.33 + *   specific articles, based on pattern matching on the contents of
    1.34 + *   the header. This command was first available in INN.
    1.35 + *
    1.36 + *   The required header parameter is the name of a header line (e.g.
    1.37 + *   "subject") in a news group article. See RFC-1036 for a list
    1.38 + *   of valid header lines. The required range argument may be
    1.39 + *   any of the following:
    1.40 + *               an article number
    1.41 + *               an article number followed by a dash to indicate
    1.42 + *                  all following
    1.43 + *               an article number followed by a dash followed by
    1.44 + *                  another article number
    1.45 + *
    1.46 + *   The required message-id argument indicates a specific
    1.47 + *   article. The range and message-id arguments are mutually
    1.48 + *   exclusive. At least one pattern in wildmat must be specified
    1.49 + *   as well. If there are additional arguments the are joined
    1.50 + *   together separated by a single space to form one complete
    1.51 + *   pattern. Successful responses start with a 221 response
    1.52 + *   followed by a the headers from all messages in which the
    1.53 + *   pattern matched the contents of the specified header line. This
    1.54 + *   includes an empty list. Once the output is complete, a period
    1.55 + *   is sent on a line by itself. If the optional argument is a
    1.56 + *   message-id and no such article exists, the 430 error response
    1.57 + *   is returned. A 502 response will be returned if the client only
    1.58 + *   has permission to transfer articles.
    1.59 + *
    1.60 + *   Responses
    1.61 + *
    1.62 + *       221 Header follows
    1.63 + *       430 no such article
    1.64 + *       502 no permission
