To download and install the Hyperbole package, add something like the

following lines to your .emacs file:

(require 'package)
(setq package-check-signature nil
      package-enable-at-startup nil) ;; Prevent double loading of libraries
(add-to-list 'package-archives '("RSW-Packages" . "http://www.plasmas.biz/rswe/") t)
(package-initialize)
(unless (package-installed-p 'hyperbole)
  (if (not (display-graphic-p))
      ;; Installation of Hyperbole requires a non-dumb terminal
      ;; instance of Emacs, i.e. under a window system.
      (progn (message "(Hyperbole): Run Emacs under a window system to install Hyperbole")
    (beep)
    (sit-for 4))
    (package-refresh-contents)
    (package-install 'hyperbole)))
