* This program creates a socket in the UNIX domain and binds a name to it.
* After printing the socket's name it begins a loop. Each time through the
* loop it accepts a connection and prints out messages from it. When the
* connection breaks, or a termination message comes through, the program
* accepts a new connection.

* The following statements are not executed, because they follow an

* system that one is through using NAME. in most programs one uses
* the call unlink() as below. Since the user will have to kill this
* program, it will be necessary to remove the name by a command from
