Class Logger

java.lang.Object

jsky.util.Logger

public class Logger
extends Object

Replacement logger that uses the Jarkarta commons logging system. Note this only provides the used parts of the original JSKY Logger class. This replacement is so that we can remove log4j and only use the Java 1.4 logger system (which is used by STARJAVA).
