+ * Provides a way of globally setting various aspects of webapp contexts.
+ * 
+ * Adding this binding will allow the user to arbitrarily apply a file of 
+ * jetty-web.xml like settings to a webapp context.
+ * 
+ * Example usage would be:
+ * - adding a server or system class setting to all webapp contexts
+ * - adding an override descriptor 
+ * 
+ * Note: Currently properties from startup will not be available for 
+ * reference.
