 /***
 24  
  * This is an example of how you would implement the finger command
 25  
  * in Java using NetComponents.  The Java version is much shorter.
 26  
  * But keep in mind that the Unix finger command reads all sorts of
 27  
  * local files to output local finger information.  This program only
 28  
  * queries the finger daemon.
 29  
  * <p>
 30  
  * The -l flag is used to request long output from the server.
