 GIJ is a Java bytecode interpreter, not limited to interpreting bytecode.
 It includes a class loader which can dynamically load shared objects, so
 it is possible to give it the name of a class which has been compiled and
 put into a shared library on the class path.
 .
 The package contains as well a collection of wrapper scripts and symlinks.
 It is meant to provide a Java-RTE-like interface to the GIJ/GCJ tool set,
 limited to the headless tools and libraries.
