  75 <h2>Sound</h2>
  76 This class represents a short wave file, in Windows WAV format, that can
  77 be stored in memory and played. Currently this class is implemented on Windows
  78 and GTK (Linux) only.
  79 <p>
  80 This demo offers two examples, both driven by buttons, but obviously the event
  81 that drives the playing of the sound can come from anywhere.
