  56.     This file has been updated to include Sound Input Manager 1.1 interfaces.
  57.  
  58.     Some of the Sound Input Manager 1.1 interfaces were not put into the InterfaceLib
  59.     that originally shipped with the PowerMacs. These missing functions and the
  60.     new 1.1 interfaces have been released in the SoundLib library for PowerPC
  61.     developers to link with. The runtime library for these functions are
  62.     installed by Sound Manager 3.2. The following functions are found in SoundLib.
