===========

Purpose
-------

To implement a central storage for objects often used throughout the
application, is typically implemented using an abstract class with only
static methods (or using the Singleton pattern)

Examples
--------

-  Zend Framework: ``Zend_Registry`` holds the application's logger
   object, front controller etc.
-  Yii Framework: ``CWebApplication`` holds all the application
   components, such as ``CWebUser``, ``CUrlManager``, etc.
