- * @ngdoc directive
- * @name angular.module.ng.$compileProvider.directive.ng-view
- * @restrict ECA
- *
- * @description
- * # Overview
- * `ng-view` is a directive that complements the {@link angular.module.ng.$route $route} service by
- * including the rendered template of the current route into the main layout (`index.html`) file.
- * Every time the current route changes, the included view changes with it according to the
- * configuration of the `$route` service.
- *
- * @scope
- * @example
