This directory contains a program to test the simulator basics.  Make the
simulator by typing `make'.  An executable `sim' will be created.  Run
this executable.  When the simualtor command prompt appears, type `test'.
A set of tests will be performed, displaying various aspects of the
network with instructions as to what should appear on the screen.  Check
that the correct items appear.  When the simulator prompt re-appears, the
test is over.  Type `q' to exit the simulator (don't bother to save the
command file).
