+/**
+ * <pre>
+ *   XPAT header range|<message-id> pat [pat...]
+ *
+ *   The XPAT command is used to retrieve specific headers from
+ *   specific articles, based on pattern matching on the contents of
+ *   the header. This command was first available in INN.
+ *
+ *   The required header parameter is the name of a header line (e.g.
+ *   "subject") in a news group article. See RFC-1036 for a list
+ *   of valid header lines. The required range argument may be
+ *   any of the following:
+ *               an article number
+ *               an article number followed by a dash to indicate
+ *                  all following
+ *               an article number followed by a dash followed by
+ *                  another article number
+ *
+ *   The required message-id argument indicates a specific
+ *   article. The range and message-id arguments are mutually
+ *   exclusive. At least one pattern in wildmat must be specified
+ *   as well. If there are additional arguments the are joined
+ *   together separated by a single space to form one complete
+ *   pattern. Successful responses start with a 221 response
+ *   followed by a the headers from all messages in which the
+ *   pattern matched the contents of the specified header line. This
+ *   includes an empty list. Once the output is complete, a period
+ *   is sent on a line by itself. If the optional argument is a
+ *   message-id and no such article exists, the 430 error response
+ *   is returned. A 502 response will be returned if the client only
+ *   has permission to transfer articles.
+ *
+ *   Responses
+ *
+ *       221 Header follows
+ *       430 no such article
+ *       502 no permission
