The Java VC is an extensible, customisable, graphical visualisation tool for ECLiPSe implemented in Java. A new Java VC can be started using the predicate <code>start_vc/1</code>. While the Java VC is running, it will react automatically to the creation of <i>viewables</i> during ECLiPSe execution. For more information on how to declare and use viewables see the documentation for <code>lib(viewable)</code>. The Java VC can be terminated from ECLiPSe using the predicate <code>stop_vc/1</code>.\n           \n")).
