-/**
- * <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
- *
- *   Response Data:
- *
- *       art_nr fitting_header_value
- * 
- * </pre>
