+					The following example, adapted from the NetworkTest plugin, shows a simple example of creating a
+					server listening on a TCP port using the cNetwork API. The server listens on port 9876 and for
+					each incoming connection it sends a welcome message and then echoes back whatever the client has
+					sent ("echo server").</p>
+					<p>
+					First, the callbacks for the listening server are defined. The most important of those is the
+					OnIncomingConnection() callback that must return the LinkCallbacks that will be used for the new
+					connection. In our simple scenario each connection uses the same callbacks, so a predefined
+					callbacks table is returned; it is, however, possible to define different callbacks for each
+					connection. This allows the callbacks to be "personalised", for example by the remote IP or the
+					time of connection. The OnAccepted() and OnError() callbacks only log that they occurred, there's
+					no processing needed for them.</p>
+					<p>
+					Finally, the cNetwork:Listen() API function is used to create the listening server. The status of
+					the server is checked and if it is successfully listening, it is stored in a global variable, so
+					that Lua doesn't garbage-collect it until we actually want the server closed.</p>
