    34       way for applications to talk to one another.
    35       <application>D-Bus</application> supplies both a system daemon (for events
    36       such as <quote>new hardware device added</quote> or <quote>printer queue

    38       among user applications). Also, the message bus is built on top of a
    39       general one-to-one message passing framework, which can be used by any two
    40       applications to communicate directly (without going through the message bus
    41       daemon).
