+used to embed scripting functionality into an application.  It supports
+QtScript as a scripting interpreter backend.
+
+Kross provides an abstract API to provide scripting functionality in a
+interpreter-independent way.  The application that uses Kross should not need
+to know anything about the scripting language being used.  The core of Kross
+provides the framework to deal transparently with interpreter-backends and
+offers abstract functionality to deal with scripts.")
