  * With JDK 1.0 appletviewer,

  *  However if you add ~/.hotjava (or the file ~/.hotjava/properties) 
  *  to acl.write, then applets loaded over the net can change your

  *  
  *  Note that under no circumentances should you allow this! 
  *  That is, never add ~/.hotjava or ~/.hotjava/properties to
  *  your acl.write list.    If you do, then applets loaded over
  *  the net will be able to change your browser properties to
  *  allow themselves to read and write to any files on your system.
