  57.     Some of the Sound Manager 3.0 interfaces were not put into the InterfaceLib
  58.     that originally shipped with the PowerMacs. These missing functions and the

  60.     developers to link with. The runtime library for these functions are
  61.     installed by Sound Manager 3.1. The following functions are found in SoundLib.
