/*
 * This example shows how to create buttons using the FSDefineButton and FSDefineButton2
 * classes. Each button displays a web page in a browser when clicked. The second button
 * also plays a sound when clicked.
 *
 * To run this example, type the following on a command line:
 *
 *     java com.flagstone.transform.examples.ConstructButtons \
 *         --font font-file \
 *         --sound sound-file \
 *         --label string \
 *        [--resultDir path]
 *
 * where
 *
 *     font-file is the path to a file containing a font definition used to 
 *     render the text for label on the button.
 *
 *     sound-file is the path to a file containing a WAVE or MP3 format sound
 *     which is played when a button is clicked.
 *
 *     string the label that will be displayed on the button - enclose in quotes 
 *     if the label contains spaces.
 *
 *     resultDir is the directory where the Flash file generated by the example 
 *     is written to.
