Some brief instructions on how to use Sprocket 2 in Rails to get CoffeeScript
powered JS and SASS powered CSS with YUI compression all via the magic of rack.

This stuff will be native in Rails 3.1 and the layout of the files on the

// Get the pagination information from the response headers

// Wrap Backbone.sync to save the pagination header on the response object.

  var success_with_pagination = function(resp, status, xhr) {
    resp.next_page = xhr.getResponseHeader('X-Next-Page');
    return success(resp);
  }
  return Backbone.sync_without_pagination(method, model, success_with_pagination, error);
