/*
 *  Node.js test runner for running data-*.js tests with Nashorn 'jjs' command
 *  running in es6 mode (a.k.a.: jjs --language=es6).
 * 
 *  If the environment variable JAVA_HOME is defined it will use it to
 *  construct the path to 'jjs' as $JAVA_HOME/bin/jjs
 *
 *  Reports discrepancies to console; fix them manually in data-*.js files.
 *  Expects a 'jjs' command in the path.  Example:
 *
 *    $ node nashorn.js
