The Drools Development Team is devotedly nursing Drools, providing the essential platform for my article, and the Drools Community has helped me to collect material for it. Therefore, I think it is only proper to inform you all that - provided you can read German - you can peruse a copy of the article Regelbasiertes Programmieren in der Bahntechnik<http://members.inode.at/w.laun/articles/Signal+Draht.html>(Rule Based Programming for Railway Applications), featuring Drools on my home page. Kind Regards Wolfgang
