public class LogConsole
extends java.io.PrintStream
implements java.io.Serializable

A companion class to LogWriter that captures System.out and System.err output and redirects the output to the MAIN log using the LogWriter.DEBUG severity level.

The LogWriter.init method optionally creates an instance of this class, depending on the boolean value passed to the method. Other classes should not reference this class or any of its methods.
