+This is an example for the QServerSocket class which is included in the
+network module.
+
+It is a simple http daemon. After starting it you can connect to port
+8080 with a web browser and an html page is shown. The program does
+not really parse the http request; so it is not of much use except for
+being a small example for QServerSocket.
