28;;; Commentary:
29
30;; Don't zone out in front of Emacs!  Try M-x zone.
31;; If it eventually irritates you, try M-x zone-leave-me-alone.
32
33;; Bored by the zone pyrotechnics?  Write your own!  Add it to
34;; `zone-programs'.  See `zone-call' for higher-ordered zoning.
35
36;; WARNING: Not appropriate for Emacs sessions over modems or
37;;          computers as slow as mine.
