-;;; Brief internal description - Skip this if your not interested!
-;;;
-;;; The function appt-check is run from the 'loadst' process which is started
-;;; by invoking (display-time). A temporary function below modifies
-;;; display-time-filter
-;;; (from original time.el) to include a hook which will invoke appt-check.
-;;; This will not be necessary in the next version of gnuemacs.
-;;;
+;;; Brief internal description - Skip this if you are not interested!
;;;
;;; The function appt-make-list creates the appointments list which appt-check
;;; reads. This is all done automatically.
;;;
;;; For instance, these variables can be set to functions that display
;;; appointments in pop-up frames, which are lowered or iconified after
-;;; appt-display-interval seconds.
+;;; appt-display-interval minutes.
