Rastl- Thanks for voting first and checking later. Or not at all.
If you look at last page of the article there is proper attribution. This is the same license as was included in WPM, so even if I didn't write it, which I did, anyone is free to post it as long as it is properly attributed per the license terms. I appreciate your concern over IP, but if you are going to raise an alarm perhaps you might consider taking a couple minutes to get your facts straight.
