This functionality has been replaced by the new sleep library which supports more then just DBUS systems. * lisp/obsolete/gnus-dbus.el: Add Obsolete-since header. Add commentary. (gnus-dbus-close-on-sleep, gnus-dbus-sleep-registration-object) (gnus-dbus-register-sleep-signal gnus-dbus-sleep-handler) (gnus-dbus-unregister-sleep-signal): Mark as obsolete.

;;; Commentary:
|
|
|
|
;; This library is obsolete.
|
|
;;
|
|
;; Use `gnus-close-on-sleep' instead.
|
|
|
|
;; This library contains some Gnus integration for systems using DBUS.
|
|
;; At present it registers a signal to close all Gnus servers before
|
|
;; system sleep or hibernation.
