To illustrate how the Qckvu Image Server works we've written a tiny Tcl/Tk program that sends commands to Qckvu over the socket.

The first step in running the demo is to start up the version of qckvu that has the TCP/IP socket. On the command line you must include the listening TCP/IP port.

Qckvu will start up, but there is no drawing loaded. It is however, listening on port 5000 for any commands that might be sent by a client.
