+Date:                    2013-04-29
+Initial Package Version: 5.17
+Upstream Status:         unknown
+Origin:                  Arch Linux (Giovanni Campagna)
+Description:             Allow using obexd without systemd in the user session
+
+Not all sessions run systemd --user (actually, the majority
+doesn't), so the dbus daemon must be able to spawn obexd
+directly, and to do so it needs the full path of the daemon.
