26 <para>D-Bus is a message bus system, a simple way for applications to talk
27 to one another. D-Bus supplies both a system daemon (for events such as
28 "new hardware device added" or "printer queue changed") and a
29 per-user-login-session daemon (for general IPC needs among user
30 applications). Also, the message bus is built on top of a general one-to-one
31 message passing framework, which can be used by any two applications to
32 communicate directly (without going through the message bus daemon).</para>
