    public class DJepApplet

extends java.applet.Applet
implements java.awt.event.ActionListener

This class implements a simple command line utility for evaluating mathematical expressions. Usage: java org.lsmp.djep.DJepConsole [expression] If an argument is passed, it is interpreted as an expression and evaluated. Otherwise, a prompt is printed, and the user can enter expressions to be evaluated. To exit from the command prompt a 'q' must be entered. typing

    diff(x^2,x)

will differentiate x^2 wrt 2. And

    eval(x^2,x,3)

will calculate x^2 at x=3. Expresions like

    eval(diff(diff(x^2+y^3,x),y),x,3,y,4)

are also allowed.
