 Here’s an example viewer for displaying ‘text/enriched’ inline:
 
      (defun mm-display-enriched-inline (handle)
        (let (text)
          (with-temp-buffer
            (mm-insert-part handle)
            (save-window-excursion
              (enriched-decode (point-min) (point-max))
              (setq text (buffer-string))))
          (mm-insert-inline handle text)))
 
    We see that the function takes a MIME handle as its parameter.  It
 then goes to a temporary buffer, inserts the text of the part, does some
 work on the text, stores the result, goes back to the buffer it was
 called from and inserts the result.
 
    The two important helper functions here are ‘mm-insert-part’ and
 ‘mm-insert-inline’.  The first function inserts the text of the handle
 in the current buffer.  It handles charset and/or content transfer
 decoding.  The second function just inserts whatever text you tell it to
 insert, but it also sets things up so that the text can be “undisplayed”
 in a convenient manner.
