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 dash3's purpose) -- new style of
35           declaring modules and processes (i.e., via the use of
36           module_name).
