果然如此, 是 1999年的一段程序, 可以向 RFC2324 来发送一个 BREW 请求.

;;; Commentary:
;; This module provides an Emacs interface to RFC2324-compliant coffee
;; devices (Hyper Text Coffee Pot Control Protocol, or HTCPCP). It
;; prompts the user for the different additives, then issues a BREW
;; request to the coffee device.
;; coffee.el requires a special BREW-capable version of Emacs/W3 to be
;; installed.
;; Reference: <URL:ftp://ftp.isi.edu/in-notes/rfc2324.txt>
;; Thanks to Giacomo Boffi <giacomo.boffi@polimi.it> for some typos
;; and the addition of the "Brown-Coffee" sweetener type.

;;; Code:

(require 'cl)

(defvar coffee-host "coffee"
  "*The host which provides the coffee service.") 

(defvar coffee-pot-designator 1
  "*On machines with multiple pots, the number of the pot to brew in")

(defvar coffee-brew-hook nil
  "*Hook executed before issuing a BREW request")

(defconst coffee-milk-types
  '("Cream" "Half-and-Half" "Whole-Milk" "Part-Skim" "Skim" "Non-Dairy"))

(defconst coffee-syrup-types '("Vanilla" "Almond" "Raspberry" "Chocolate"))

    ("Syrup"     . ,coffee-syrup-types)

         (url-request-data "START"))

         (type (cdr (assoc type-name coffee-addition-types)))
         (ingredients (mapcar #'(lambda (a) (cons a a)) type))
          (completing-read "Addition type: " ingredients nil t)))
(defun coffee-url ()
  (require 'w3-forms)
  (concat "coffee://" coffee-host "/"
          (int-to-string coffee-pot-designator)
