libdbus-1-3 1.0.2-1ubuntu3 (sparc binary) in ubuntu gutsy

 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.
 .
 D-Bus is still under heavy development, but is expected to be widely
 used. It comes with several interfaces, including GLib. See the
 description of libdbus-glib-1-2 for more information about those.
 .
 The daemon can be found in the dbus package.
