Rails 3.1 Where to put some application.coffee code ? file tree

In 3.0 we are using an application.coffee file and some specific controllers .coffee files using the following file tree

- app   - coffescripts         > application.coffee         - controllers               > control1.coffee               > control2.coffee

In 3.1 , I wonder where I should put the former application.coffee scripts , as the structure as been changed in it seems not to be recommended to write code directly into the application.js file

- app    - assets       - javascripts           > application.js           - controllers               > control1.coffee               > control2.coffee

thanks for your feedback
