-;;; Commentary:
-;;;
-;;; This module supports the configuration of the D-Bus message bus
-;;; (http://dbus.freedesktop.org/). D-Bus is an inter-process communication
-;;; facility. Its "system bus" is used to allow system services to
-;;; communicate and be notified of system-wide events.

-

-@code{etc/dbus-1/system.d} directories of each package listed in
