examples/chat/README

-
-This example is a simple instant messaging implementation. There are multiple
-participants in the chat, both sending and reading messages. The sending
-application 'prompt' is separated from the application displaying the chat
-'display' so that there's no need for sophisticated GUI.
-
-To run the example you'll need both applications plus the 'forwarder' device
-that will play role of messaging server (chatroom). Build it this way:
-
-$ ./autogen.sh
-$ ./configure --with-chat --with-forwarder
-$ make
-$ sudo make install
-
-Once it is built create the configuration file (say config.xml) for the
-forwarder describing which network endpoints are to be used for incoming and
-outgoing messages:
-
-<forwarder>
-    <in>
-        <bind addr = "tcp://eth0:5555"/>
-    </in>
-    <out>
-        <bind addr = "tcp://eth0:5556"/>
-    </out>
-</forwarder>
-
-You are of course free to define mutliple endpoints for either incoming or
-outgoing messages.
-
-Now start the forwarder:
-
-$ zmq_forwarder ./config.xml
-
-At this point the messaging server is ready to accept connections from
-messaging clients. When starting the sending application, specify your name
-so that messages can be attributed to you:
-
-$ ./prompt tcp://myserver:5555 "John Doe"
-
-$ ./display tcp://myserver:5556
