XULRunner is a single "gecko runtime" installable package that can be used to bootstrap multiple XUL+XPCOM applications that are as rich as Firefox and Thunderbird. It will provide mechanisms for installing, upgrading, and uninstalling these applications. XULRunner will also provide libxul, a solution which allows the embedding of Mozilla technologies in other projects and products. Based on an initial port by James Wright <jamesw at bsdhosting.co.za>. Improvements and okay steven@
