<longdescription lang="en">
  Kawa is a full Scheme implementation. It implements almost all of R5RS,
  plus some extensions. By default, symbols are case sensitive. It is
  completely written in Java. Scheme functions and files are automatically
  compiled into Java byte-codes. Kawa does some optimizations, and the
  compiled code runs at reasonable speed.
