+     "GNU Kawa is an implementation of the Scheme programming language that
+is built on top of the Java platform.  It is thus conveniently integrated
+with Java and benefits from this by having a compiler, optional static
+typing, and so on.  Kawa also serves as a framework for implementing other
+programming languages on the Java platform.  Included in Kawa is qexo, a
+partial implementation of XQuery in Java.")
