+Hello!
+
+KTron is a simple tron-clone for the K Desktop Environment.
+I think it's just nothing to say about the game:
+avoid running into walls, your own tail, and that of your opponent.
+
+Read the Online-Documentation for more details.
+
+
+Notice:
+Parts of the code, especially parts of the algorithm for the computerplayer
+are from xtron-1.1 by Rhett D. Jacobs <rhett@hotel.canberra.edu.au>

+KTron in general does everything I wanted it to do. :-)
+
+Plans for the future are:
+- possibility to create, load, save playfield with walls
