  11. * socket interface to communicate actions between the server
  12. * and client such as keyboard activity, mouse movement, responses
  13. * to client events, etc., as well as to communicate requests from
  14. * the client to the server, such as creation of new windows,
  15. * movement, resizing, and display updates.
