;;; Commentary:
;;
;; notes:
;;
;;   -repeat after me: "the colon is not part of the header name..."
;;   -if w3 becomes part of emacs, then it may make sense to have this
;;    file depend on w3 -- the maintainer of w3 says merging with Emacs
;;    is planned!
;;
;; historical note:
;;
;;   this is intended as a replacement for mailto.el
;;
;; acknowledgments:
;;
;;   the functions that deal with unhexifying in this file were basically
;; taken from w3 -- i hope to replace them with something else soon OR
;; perhaps if w3 becomes a part of emacs soon, use the functions from w3.
