  // The name of the route.

  // for the route if none is provided in the "template" option. If no name is
  // provided, the router guesses a name based on the path '/post/:_id'
  name: 'post.show',

  // To support legacy versions of Iron.Router you can provide an explicit path
  // as an option, in case the first parameter is actually a route name.
  // However, it is recommended to provide the path as the first parameter of the
  // route function.
  path: '/post/:_id',

  // If we want to provide a specific RouteController instead of an anonymous
  // one we can do that here. See the Route Controller section for more info.

  // If the template name is different from the route name you can specify it
  // explicitly here.
  template: 'Post',

  // A layout template to be used with this route.

  // be used.

  // A data function that can be used to automatically set the data context for
  // our layout. This function can also be used by hooks and plugins. For
  // example, the "dataNotFound" plugin calls this function to see if it
  // returns a null value, and if so, renders the not found template.

  // The same thing as providing a function as the second parameter. You can
  // also provide a string action name here which will be looked up on a Controller
  // when the route runs. More on Controllers later. Note, the action function
  // is optional. By default a route will render its template, layout and
  // regions automatically.
  // Example:
  //  action: 'myActionFunction'
  action: function () {
    // render all templates and regions for this route
    this.render();
  }
