tar2rubyscript and rubyscript2exe for rails 3.x

Hi, Greetings to all…!

I have successfully created executable files for rails 2.x with ruby 1.8.x . Followed the tutorial: http://www.erikveen.dds.nl/distributingrubyapplications/rails.html

How can I do this for Rails 3.x applications.

I am Using UBUNTU

Expecting your valuable suggestions.

Thank you.
