Abstract:

Discusses how XML is used in the configuration of GUI interfaces. He looks at Mozilla's XML-based User Interface Language (XUL) which allows you to write applications that run without any particular dependency on the choice of underlying operating system. This may seem strange at first, but you'll soon see that this Mozilla project offers powerful tools for GUI building that allow you to develop for an extensive base of installed users.
