+/**
+ * @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
