  11 // protocol defintions were not present in earlier releases of the Mac OS X
  12 // SDK.  In order to support building against the new SDK, which requires
  13 // delegates to conform to these protocols, and earlier SDKs, which do not
  14 // define these protocols at all, this file will provide empty protocol
  15 // definitions when used with earlier SDK versions.
