New tool for trying and testing JRuby+Truffle

[Petr Chalupa]

Hello,

there was a new tool for JRuby+Truffle added recently. It is a small 
command line utility designed to run and test Ruby gems and applications 
on JRuby+Truffle Ruby runtime. It uses other Ruby implementation to 
prepare environment and to execute files, tests on JRuby+Truffle.

It simplifies running a Ruby file from a gem to just few steps:

- cd to gem's directory
- run jruby+truffle setup
- run jruby+truffle run the_file.rb

Please see Readme [0] for more information.
