/**
 * Launches the International Sample Application.  Constructed using
 * the Applet Wizard, IntlDemo.java works both as an applet and an
 * application.  When run as an application without
 * command-line parameters, TextDataFiles are used as the data source.
 * If JDBC connection parameters are passed as command-line
 * parameters, the specified JDBC database will be used.
 * Running as an applet displays a button which when pushed
 * starts running the application.
