  15.     You may incorporate this sample code into your applications without
  16.     restriction, though the sample code has been provided "AS IS" and the
  17.     responsibility for its operation is 100% yours.  However, what you are
  18.     not permitted to do is to redistribute the source as "DSC Sample Code"
  19.     after having made changes. If you're going to re-distribute the source,
  20.     we require that you make it clear in the source that the code was
  21.     descended from Apple Sample Code, but that you've made changes.
