How to figure out pre-installed ROR versions on a machine

Just in case, you are handed an already configured machine, complete with ROR setup.

To save some noise pollution asking people around for ROR environment/versions in your pre-configured machine :),

you are better off using the following command -

> ruby script\about

Would return something like this -

About your application's environment
