If you then run the tcl programs in this subdirectory, you can save the pictures to postscript. The two yes modes do slightly different things.  If you are interested in saving pictures, you have to experiment. Mainly the export feature is present for my own personal use, so that I can illustrate my monograph.  Java does have its own postscript generating capabilities, but it is rather complicated and adds a lot of overhead to the program.\n\n ";

The last 3 calculations play the role of small but formal computer-aided proofs.   These calculations do not have much visible output.  The computer simply runs the calculations and then stop.  In several cases, a few lines are printed on the command line, assuming that the program is launched from a terminal. In principle, the user could trace through the code and verify that the given calculation is done.";

The Pinwheel Lemma states that the first return map for outer billiards on kites is the product of 8 simpler maps, which I call strip maps. When you select this option, you then see 3 integer selectors appear below.  If the first integer selector says 256, it means that you are sampling the parameters 1/256,...,255/256 in the kite parameter interval (0,1).  If the second integer selector says 1024, it means that you are sampling 1024 points per unit.  If the third integer says 8, it means that you are sampling points from the sets (0,8) times {-1,1}. the total number of tests you make is the product of the 3 numbers. You can change these numbers, and their new meanings will be similar.";
