// ThreadedScoreServer.java
// Andrew Davison, March 2002, [e-mail]

/* A threaded server that stores a client's score (and name) in a
   list of top-10 high scores.

   The list is maintained in a file SCORFN, and loaded when the
   server starts.
   The server is terminated with a ctrl-C

   The server processes a client by creating a 
   ThreadedScoreHandler object.
