   * A Usenet article, either single-part or multipart.
   * To lessen the memory footprint of large binaries groups,
   * Pan folds multipart posts into a single Article object.
   * Only minimal information for any one part is kept
   * (message-id, line count, byte count), and the Article object
   * holds the rest.
   * This is a lossy approach: less-important unique fields,
   * such as the part's xref and time-posted, are not needed
   * and so we don't keep them.

       * The fields of a single part of a multipart Article.
       * For other fields, refer to the parent Article object.
