org.jruby.embed.ScriptingContainer.runScriptlet()
Evaluates a script under the current scope (perhaps the top-level scope) and returns a result only if a script returns a value. Right after the parsing, the script is evaluated once. @param script is a Ruby script to get run @return an evaluated result converted to a Java object
