libdbus-glib-1-2 0.112-2build1 (s390x binary) in ubuntu lunar

 D-Bus is a message bus, used for sending messages between applications.
 Conceptually, it fits somewhere in between raw sockets and CORBA in
 terms of complexity.
 .
 This package provides a deprecated GLib-based shared library for
 applications using the GLib interface to D-Bus. New code should use
 GDBus, part of GLib, instead.
 .
 See the dbus description for more information about D-Bus in general.
