@cindex MIME messages (Rmail)
+@vindex rmail-enable-mime
+ Rmail, by default, decodes a MIME message and display the body
+part(s) in a humar readable way. If the message contains multiple
+parts (entities), each part has an additional single tagline that
+contains the information about depth, index, and type of the part. It
+may also contain buttons to handle the part (for saving or
+image-showing).
+
+ If you customize @code{rmail-enable-mime} to @code{nil} (the default
+is @code{t}), Rmail does not show MIME decoded message until a user
+explicitly requires it.
+

- The @kbd{v} (@code{rmail-mime}) command creates a temporary buffer
-displaying the current MIME message. By default, it displays plain text
-and multipart messages, and offers buttons to save attachments.
+ The @kbd{v} (@code{rmail-mime}) command toggles the display of a
+MIME message between the raw mode and the default mode. In the raw
+mode, the undecoded MIME data is displayed. With a prefix argument,
+it toggles the display of only an entity at point.
+
+ But, if the variable @code{rmail-enable-mime} is @code{nil}, the
+command creates a temporary buffer displaying the current MIME
+message. By default, it displays plain text and multipart messages,
+and offers buttons to save attachments.
