The XULRunner project is a Mozilla runtime package that can be used to bootstrap XUL+XPCOM applications that are as rich as Thunderbird and Firefox. 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. Note: If you have to install jdk you need to run ". /etc/profile" before trying to compile xurlrunner. Optional dependencies are avahi, gnome-vfs, libbonobo, and libgnome.
