dbus 1.4.18-1ubuntu1.4 (i386 binary) in ubuntu precise

 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.
 .
 D-Bus supports broadcast messages, asynchronous messages (thus
 decreasing latency), authentication, and more. It is designed to be
 low-overhead; messages are sent using a binary protocol, not using
 XML. D-Bus also supports a method call mapping for its messages, but
 it is not required; this makes using the system quite simple.
 .
 It comes with several bindings, including GLib, Python, Qt and Java.
 .
 This package contains the D-Bus daemon and related utilities.
 .
 The client-side library can be found in the libdbus-1-3 package, as it is no
 longer contained in this package.
