# Short-Description: D-BUS is a message bus system, a simple way for applications to talk to one another.
# Description:       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).
