+This is a proof-of-concept that uses ZeroMQ as transport.
+It uses a star topology as opposed to the native mesh network.
+
+Package ZMQ must be installed. All workers only run on localhost.
+
+All Julia nodes only connect to a "broker" process that listens on known ports
+8100 and 8101 via ZMQ sockets.
+
+
+All commands must be run from `examples/clustermanager/0mq` directory
+
+First, start the broker. In a new console type:
+    julia broker.jl
+
+This does not return.
+
+Next, start a Julia REPL and type:
+    include("ZMQCM.jl")
+    ZMQCM.start_master(4) # start with four workers
+
+
+Alternatively, head.jl, a test script could be run. It just launches the requested number of workers,
+executes a simple command on all of them and exits.
+    julia head.jl 4
+
+NOTE: As stated this is a proof-of-concept. A real Julia cluster using ZMQ will probably use
+different ZMQ socket types and optimize the transport.
