/** Sample code that uses the JSE-223 pluggable scripting language interface
* to instantiate and use luaj.
*
* <p>In this case, Globals are only indirectly constructed as a side effect
* of using the scripting interface.
*
* <p>All features should be supported including compiled scripts.
*
* <p>Configuration is via system properties:
* <ul><li><b>"org.luaj.luajc"</b> - set to "true" to use the LuaJC lua-to-Java-bytecode compiling.
* Requires the bcel library to be on the class path.
* </li><li><b>"org.luaj.debug"</b> - set to "true" to load the debug library,
* which may provide better stack traces for closures.
* </li></ul>
*
* <p> These flag values can be set on the command line or via code.
