From 72cf25fe5d2ea6ae1b78bf2d1be7adcc5e292030 Mon Sep 17 00:00:00 2001
From: keiichi <keiichi>
Date: Sun, 26 Dec 1999 07:55:59 +0000
Subject: [PATCH] (TopLevel): Require `mime' and `eword-deocode' instead of
 `mmbuffer'. (mmgnus-entity): Rename from
 `mime-gnus-handle-entity' and use `mime-entity' as parent
 class.  Add slot `body' and `header'.
 (mmgnus-visible-field-p): New function. (copy from
 `mime-visible-field-p' in FLIM's mmbuffer.el)
 (mmgnus-insert-header-from-string): New function.
 (mime-insert-header): Define new method.
 (mime-entity-content): Likewise. (mime-gnus-entity): Use
 `mmgnus-entity' as parent class.
