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, an embedding framework which provides an embedding mechanism suitable for each platform.
XULRunner is not an appropriate solution for small devices which cannot take the full memory or download weight of the XULRunner featureset. XULRunner must remain a relatively lightweight runtime. At the present time XULRunner applications are not expected to be forwards-compatible, and should be marked as compatible with a specific XULRunner version.
The ultimate "make" utility.
XPath is a language for addressing parts of an XML document, designed to be used by both XSLT and XPointer.
