rhino.js

/*
 *  Node.js test runner for running data-*.js tests with Rhino's interpreter
 *  running in es6 mode (a.k.a.: -version 200).
 * 
 *  If the environment variable JAVA_HOME is defined it will use it to
 *  construct the path to 'java' as $JAVA_HOME/bin/java
 *
 *  Reports discrepancies to console; fix them manually in data-*.js files.
 *  Expects a 'rhino.jar' file in this directory. Example:
 *
 *    $ node rhino.js
 *
 *  Any syntax tested that is unsupported by Rhino will output to stderr. To make the
 *  output of this file more useful, redirect stderr to /dev/null or elsewhere. Example:
 *
 *    $ node rhino.js 2>/dev/null
