  * Demo example of a route planning agent application with GUI. The main method
  * starts a map agent frame and supports runtime experiments. This
  * implementation is based on the {@link aima.search.map.MapAgent} and the

+ * {@link aima.search.map.MapEnvironment}. It can be used
  * as a code template for creating new applications with different specialized
