Introductory Tour of Mozilla's XUL
XUL is an XML-based technology for expressing the GUI part of a software application. It has been used to express GUIs for applications as diverse as web browsers, email clients, calendars, calculators, spreadsheet editors, HTML editors, debuggers, and whole desktop environments. The free Mozilla platform—that is, the executable engine and libraries that accompany every Mozilla-based product—provides a fully-featured implementation of XUL. This article is a quick look at the main tags that Mozilla's XUL provides."
