-alfred runs as daemon in the background of the system. A user may insert
-information by using the alfred binary on the command line, or use special
-programs to communicate with alfred (done via unix sockets). alfred then takes
-care of distributing the local information to other alfred servers on other
-nodes. This is done via IPv6 link-local multicast, and does not require any
-configuration. A user can request data from alfred, and will receive the
-information available from all alfred servers in the network.
