;;; Commentary:
-;; Note: You need to have `url' and `w3' installed for this backend to
-;; work.
-
-;; A lot of codes stolen from mail-source, nnslashdot, nnweb.
-
-;; Todo: To support more web archives.
+;; Note: You need to have `url' (w3 0.46) or greater version
+;; installed for some functions of this backend to work.
-;; Known bugs: in w3 0.44, there are two copies of url-maybe-relative.
-;; If it is loaded from w3.el, (load-library "url"). w3 0.45 should
-;; work.
+;; Todo:
+;; 1. To support more web archives.
+;; 2. Generalize webmail to other MHonArc archive.
