/**
  * This class encapsulates Browser into an applet.
  * Instead of arguments to the command line for initializing each
  * panel, this applet finds the initialization arguments in the
  * applet parameters named 'providerN' where N is the N'th panel.
  * The value of each parameter has the same format as the command line
  * parameters. See browser.html for examples.
  *<p>
  * You need a Web Browser that can run Swing 1.0.
