    (description
     "D-Bus is a message bus system, a simple way for applications to
talk to one another. In addition to interprocess communication, D-Bus
helps coordinate process lifecycle; it makes it simple and reliable to
code a \"single instance\" application or daemon, and to launch
applications and daemons on demand when their services are needed.

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 apps
to communicate directly (without going through the message bus
daemon). Currently the communicating applications are on one computer,
or through unencrypted TCP/IP suitable for use behind a firewall with
shared NFS home directories.")
