(...) The problem is that the J is LeJOS means Java. LeJOS is a Java OS for a LEGO brick, in this case (i.e., LeJOS NXJ) it is for the NXT. So it is very confusing to have your OS be called LeJOS OSEK. It would be really good if you would rename it (...) (17 years ago, 10-Aug-07, to lugnet.robotics)
