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