;;; 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 w/ Emacs
;; is planned!
;;
;; historical note:
;;
;; this is intended as a replacement for mailto.el
;;
;; acknowledgements:
;;
;; the functions that deal w/ unhexifying in this file were basically
;; taken from w3 -- i hope to replace them w/ something else soon OR
;; perhaps if w3 becomes a part of emacs soon, use the functions from w3.
;;; History:
;;
;; 0.3:
;;
;; added the constant rfc2368-version
;; implemented first potential fix for a bug in rfc2368-mailto-regexp
;; implemented first potential fix for a bug in rfc2368-parse-mailto
;; (both bugs reported by Kenichi OKADA)
;;
;; 0.2:
;;
;; started to use checkdoc
;;
;; 0.1:
;;
;; initial implementation
;;; Code:
;; only an approximation?
;; see rfc 1738
