22  main.cpp -- Main function for the dashboard controller for a
23           car. This controller contains a speedometer, two odometers (total
24           and partial distance), the driver of the car, clocks, and the
25           pulse generator. The pulses are generated by the sensors placed
26           around one of the wheel shafts. The rate of pulse generation is
27           determined by the speed of the car. The driver can start the car,
28           set its speed, reset the partial distance odometer, and stop the
29           car (which means he will stop the simulation). One of the clocks
30           is slow and the other is fast. The fast clock represents the real
31           time. The slow clock is used to control the actions of the
32           driver. The signals in this program are traced.
33
34           purpose (in terms of changes to dash6's purpose) -- named port
35           binding mixed with bind(). Example: let m1 and m2 be two modules,
36           and p1 and p2 be their ports. Let m2 contain m1. Let's bind these
37           ports. In dashX with X <= 6, the binding is done in m2's
38           constructor as m1->p1.bind(p2). In this test, the binding is named
39           in that the binding is done in m2's constructor as m1->p1(p2).
40
41           The output of this program is identical to that of dash6.
