dbus-x11 - 1.16.0-1 main

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 automatically
launches one D-Bus session bus per X11 display per user. If the
dbus-user-session package is also installed, it takes precedence over
this package.
.
See the dbus description for more information about D-Bus in general.
