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