+ * ModuleActivator represents a module that plugs into the Tuscany system. Each 
+ * module should provide an implementation of this interface and register the 
+ * ModuleActivator implementation class by defining a file named 
+ * 
+ * "META-INF/services/org.apache.tuscany.core.ModuleActivator"
+ * 
+ * The content of the file is the class name of the ModuleActivator implementation. 
+ * The implementation class must have a no-arg constructor. The same instance 
+ * will be used to invoke all the methods during different phases of the module 
+ * activation. Note that the start and stop methods defined by this interface
+ * take a reference to the Tuscany SCA runtime ExtensionPointRegistry. This 
+ * gives the ModuleActivator the opportunity to add extension points to the
+ * registry as it is requested to start up and remove them when it is requested
+ * to shut down.
+ * 
+ * @version $Rev$ $Date$
