+In order to register methods on the D-Bus, Emacs has to request a well

+clients.  Names on the D-Bus can be registered and unregistered using
+the following functions:
+
+@defun dbus-register-service bus service &rest flags
+Register the known name @var{service} on D-Bus @var{bus}.
+
+@var{bus} is either the symbol @code{:system} or the symbol

+@var{service} is the service name to be registered on the D-Bus.  It

+@var{flags} is a subset of the following keywords:
+
+@itemize
+@item @code{:allow-replacement}: Allow another service to become the primary
