+Endpoint Decorator
+------------------
+
+When you want to use the werkzeug routing system for more flexibility you
+need to map the endpoint as defined in the :class:`~werkzeug.routing.Rule` 
+to a view function. This is possible with this decorator. For example:: 
+
+    from flask import Flask
+    from werkzeug.routing import Rule
+
+    app = Flask(__name__)                                                          
+    app.url_map.add(Rule('/', endpoint='index'))                                   
+
+    @app.endpoint('index')                                                         
+    def my_index():                                                                
+        return "Hello world"     
+
