public class PrefixPrintStream

extends java.io.PrintStream

This class is a slight modification of the standard PrintStream (which is derived from a FilterStream) to append a prefix to any line message (eg. println(String)) sent to the stream. By reassigning System.err to an instantiation of this class, all error messages can have an "Error: " prefix automatically inserted.
