  41.  * This Java3D program:
  42.  *    Creates an instance of the JavaSoundMixer AudioDevice, initializing it
  43.  *         and attaching it to the PhysicalEnvironment with a special version
  44.  *         of UniverseBuilder (UniverseBuildJS).
  45.  *    Creates one Point sound sources.
  46.  *    Creates two Soundscapes with their own aural attributes.  Each
  47.  *         of these Soundscapes defines its own bounding leaf region.
  48.  *    Creates and executes a custom behavior (AudioBehaviorMoveOne) that
  49.  *         starts sound playing and transforms the AuralAttribute positions
  50.  *         by modifying the TransformGroup that contains both soundscape
  51.  *         nodes.
  52.  * Usage: java MoveAppBoundingLeaf [ URLpath [ name ]]
  53.  *
  54.  * The first optional command line parameter is the URL path to directory
  55.  *    containing:
  56.  *       (1) the files that will be named on the command line, or
  57.  *       (2) the javaone/data/sounds directory that contains the default files
  58.  *    If not given the default path is:
  59.  *       file:/net/java3d/export/java3d/javaone/data/sounds
  60.  *    NOTE: This default path is only valid on Solaris Eng Menlo Park network.
  61.  *    A path must be supplied if sound files to be used are in a different
  62.  *    directory location.
  63.  *    NOTE: When running on Java3D Menlo Park Test WinTel platform path should
  64.  *    be set to
  65.  *       file:/java3d/export/java3d/javaone/data/sounds
  66.  *
  67.  * The second thru fourth optional command line parameters are sound file names
  68.  *    If not given the default file name is:
  69.  *       unicycle_close.au
