 DOCUMENTATION

 Three system print messages are supported:

  void sys_error (char*);
  void sys_halt (char*);
  void sys_message (char*);
    sys_error and sys_halt will terminate the program, sys_message
    will print a message. 

 PRINTFLAG controls the printing of sys_messages and sys_errors.  If
 PRINTFLAG is FALSE, then messages are suppressed.  The default is TRUE.

 EM can be set to the EventManager.  If it is set then a Termination
 event is triggered before sys_halt terminated the application.

 assert is used in a few places to test assertions.
