I just removed some copyvio material that an editor had attributed to http://www.as-tn.com. Wikipedia's copyright policies prevent us from incorporating proprietary material by other authors, so I took it out wholesale. I unfortunately know too little about the field to try to reword it myself to avoid the copyright issue, but perhaps a knowledgable user could refer to the URL above to add more information.
