dbus 0.60-2ubuntu12 (powerpc binary) in ubuntu dapper

 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 dbus-glib-1 for more information about those.
 .
 This package contains the D-BUS daemon; the client-side library can
 be found in the libdbus-1-2 package, as it is no longer contained in
 this package.
