dbus: D-Bus is a message bus system, a simple way for applications to talk to 
dbus: one another. D-Bus supplies both a system daemon (for events such as 
dbus: “new hardware device added” or “printer queue changed”) and a 
dbus: per-user-login-session daemon (for general IPC needs among user 
dbus: applications). Also, the message bus is built on top of a general 
dbus: one-to-one message passing framework, which can be used by any two 
dbus: applications to communicate directly (without going through the message 
dbus: bus daemon).
