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

46 Even though <application>D-Bus</application> was built in LFS, there are
