Backbone.js & require.js: how do I transform my models, views and collections to require.js modules?

I am working on a javascript app with backbone.js, that said, for ease of development I structure my files this way

app
 |
 + views
 |    L movieRow.js
 |    L movieDetail.js
 |
 + models
 |    L movie.js
 |    L tvshow.js
 |
 + collections
 |    L movies.js
 |    L tvshows.js
 |
 + templates
 |    L movieList.tpl
 |    L movieDetail.tpl
 |    L applicationUI.tpl
 |
 L application.js

now, that are a lot of javascript files to server to the user, I see some buzz about labjs or require.js and decided to test around with it. but i have no idea how i would rewrite all my backbone models or views into these require.js modules.

any help in the right direction would be nice.
