Class MirageDriver

java.lang.Object

uk.ac.starlink.mirage.MirageDriver

public class MirageDriver
extends Object

Main application class for the StarTable Mirage front-end. The class named by MIRAGE_CLASS must be on the JVM's classpath in order for this to work. No Mirage components need to be available during compilation or distribution of this code however. This is desirable since Mirage is distributed under a more restrictive licence than the GPL.
