/* Created by : Alexander Yanuar KOENTJARA - LexZEUS, 28-Jun-2000 E-Mail : lexzeus@hotmail.com Homepage : http://lexzeus.tripod.com To work properly, this class needs mines.class in its folder/directory. As a open source program, you can use my "lexSweeper v1.0" in your web site, modify, or distribute it as your wish, but you must include my name as the author in the source code. Also, I make the code with a nice indents, so even a beginner can learn to know how my code works. You know, it's a bad habbit for some of programmers to be so selfish to write their codes within very awful indents, it won't help other people to debug or modify if there's something error inside, unless their code is for private used.
