Binary package “dbus-x11” in ubuntu quantal
simple interprocess messaging system (X11 deps)
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 contains the dbus-launch utility which is necessary for
packages using a D-Bus session bus.
See the dbus description for more information about D-Bus in general.
