+      GNU Ball and Paddle is an old-fashioned ball and paddle game
+      with a set amount of blocks to destroy on each level, while
+      moving a paddle left and right at the bottom of the
+      screen.  Various powerups may make different things occur.
+
+      It now uses GNU Guile for extension and the levels are written
+      with Guile.  Follow the example level sets and the documentation.
