# Short-Description: D-Bus is a message bus system for applications to talk to one another.
# Description:       D-Bus supplies both a system daemon and a per-user-login-session daemon.
#                    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).
