*
* java -cp ... com.flagstone.cookbook.BasicButtonSound sound-file file-out
*
* where:
*
* sound-file is the path to a file containing a WAVE or MP3 format sound
* which is played when a button is clicked.
*
* file-out is the path where the file will be written. If no output file
* is specified then a file named after the example will be written to the
