;;; Commentary:
;; Turning on eev-mode simply activates the eev-mode-map keymap, and
;; adds an "eev" to the mode line to remind you this. Turning off
;; eev-mode deactivates the keymap and the reminder. If you want an
;; eev-mode-map with fewer or other bindings, follow the instructions
;; here:
;; (find-eev "eev-mode.el" "when-not-eev-mode-map")
;; «.eev-mode-map-set» (to "eev-mode-map-set")
;; «.when-not-eev-mode-map» (to "when-not-eev-mode-map")
