All Implemented Interfaces:

javax.accessibility.Accessible, java.awt.event.ActionListener, java.util.EventListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable

public class SimpleCLI

extends java.awt.Frame

implements java.awt.event.ActionListener

Creates a very simple command line for invoking the main method of classes. System.out and System.err are redirected to an output area. Features a simple command history -- use up and down arrows to move through previous commmands. This gui uses only AWT (i.e. no Swing).
