-;; In Emacs-21.3, the manual documented the following procedure to
-;; activate this package:
-;; (display-time)
-;; (add-hook 'diary-hook 'appt-make-list)
-;; (diary 0)
-;; The display-time call was not necessary, AFAICS.
-;; What was really needed was to add the hook and load this file.
-;; Calling (diary 0) once the hook had been added was in some sense a
-;; roundabout way of loading this file. This file used to have code at
-;; the top-level that set up the appt-timer and global-mode-string.
-;; One way to maintain backwards compatibility would be to call
-;; (appt-activate 1) at top-level. However, this goes against the
-;; convention that just loading an Emacs package should not activate
-;; it. Instead, we make appt-make-list activate the package (after a
-;; suggestion from rms). This means that one has to call diary in
-;; order to get it to work, but that is in line with the old (weird,
-;; IMO) documented behavior for activating the package.
-;; Actually, since (diary 0) does not run diary-hook, I don't think
-;; the documented behavior in Emacs-21.3 would ever have worked.
-;; Oh well, at least with the changes to appt-make-list it will now
-;; work as well as it ever did.
-;; The new method is just to use (appt-activate 1).
