Installation of this extension follows the usual pattern:

  ./CASCADE-MAKE.sh

Note: Jena is a pure Java code base, and the relevant compiles jar
      files are bundled with this extension, so no actual compilation
      is needed.  The main task CASCADE-MAKE.sh does is to untar the
      'binary' files, and setup them up in appropriate top-level '
      lib' folder (for jar files) etc so Greenstone can find them


      In case it is every needed the companion source code is in 'src'
      (from the Apache Jena website, matched to the binary version).
      For source code, there is only a zip version of the file to
      download.
