;;; Commentary:
;; appt.el - visible and/or audible notification of
;; appointments from diary file.
;;
-;;;
-;;; Thanks to Edward M. Reingold for much help and many suggestions,
-;;; And to many others for bug fixes and suggestions.
-;;;
-;;;
-;;; This functions in this file will alert the user of a
-;;; pending appointment based on his/her diary file. This package
-;;; is documented in the Emacs manual.
-;;;
-;;; To activate this package, simply use (appt-activate 1).
-;;; A `diary-file' with appointments of the format described in the
-;;; documentation of the function `appt-check' is required.
-;;; Relevant customizable variables are also listed in the
-;;; documentation of that function.
-;;;
-;;; Today's appointment list is initialized from the diary when this
-;;; package is activated. Additionally, the appointments list is
-;;; recreated automatically at 12:01am for those who do not logout
-;;; every day or are programming late. It is also updated when the
-;;; `diary-file' is saved. Calling `appt-check' with an argument forces
-;;; a re-initialization at any time.
-;;;
-;;; In order to add or delete items from today's list, without
-;;; changing the diary file, use `appt-add' and `appt-delete'.
-;;;
-
-;;; Brief internal description - Skip this if you are not interested!
-;;;
-;;; The function `appt-make-list' creates the appointments list which
-;;; `appt-check' reads.
-;;;
-;;; You can change the way the appointment window is created/deleted by
-;;; setting the variables
-;;;
-;;; appt-disp-window-function
-;;; and
-;;; appt-delete-window-function
-;;;
-;;; For instance, these variables could be set to functions that display
-;;; appointments in pop-up frames, which are lowered or iconified after
-;;; `appt-display-interval' minutes.
