%description
    This is a glue package to provide a minimum Sun Java JDK/JRE like
    command interface to the GCJ/GIJ based Java tool chain and their
    companion tools. It is *NOT* a complete JDK/JRE, but at least
    provides the most important tools for compiling and running non-GUI
    Java 1.4 applications.
