Where to download rails.js?

Question

I believe that rails.js is required for :remote => true to work on rails forms, but I don't have rails.js in my public/javascripts folder. I have:

application.js
jquery.js
jquery.min.js
jquery-ui.js
jquery-ui.min.js
jquery-ujs.js
jrails.js

How do I get rails.js? Thanks
