-## The DBus Interface

-When compiled with the optional `with_dbus` flag, xmobar can be
-controlled over dbus. All signals defined in [src/Signal.hs] as `data
-SignalType` can now be sent over dbus to xmobar. Due to current
-limitations of the implementation only one process of xmobar can
-acquire the dbus. This is handled on a first-come-first-served basis,
-meaning that the first process will get the dbus interface. Other
-processes will run without further problems, yet have no dbus
-interface.
