;;    Extensions to `timer.el'.
;; 
;; 
;;  ***** NOTE: The following function defined in `timer.el' has
;;              been REDEFINED HERE:
;;
;;  `cancel-function-timers' - 
;;     This now uses `completing-read' in the interactive spec, with,
;;     as default, `symbol-nearest-point'.
;;
;;
;;  This file should be loaded after loading the standard GNU file
;;  `timer.el'.  So, in your `~/.emacs' file, do this:
;;  (eval-after-load "timer" '(require 'timer+))
