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