-This draws a sonar screen that pings (get it?) the hosts on
-your local network, and plots their distance (response time) from you.
-The three rings represent ping times of approximately 2.5, 70 and 2,000
-milliseconds respectively.
+A sonar display pings (get it?) the hosts on your local network, and
+plots their distance (response time) from you. The three rings
+represent ping times of approximately 2.5, 70 and 2,000 milliseconds
+respectively.
Alternately, it can run a simulation that doesn't involve hosts.
-(If pinging doesn't work, you may need to make the executable be setuid.)
