/**
* Support for alternate implementations of Google App Engine services. This package is not
* intended for use by application code.
*
* If, for example, vendor X wanted to provide an alternate implementation of the
* DatastoreService, they would have to provide an implementation of {@link
* com.google.appengine.api.datastore.IDatastoreServiceFactory} that returns their implementation
* for {@link com.google.appengine.api.datastore.DatastoreService}.
*
*
Factory implementations are acquired using a {@link com.google.appengine.spi.FactoryProvider
* FactoryProvider} registered with {@link com.google.appengine.spi.ServiceFactoryFactory
* ServiceFactoryFactory}. These providers are typically discovered using {@link
* java.util.ServiceLoader}; see {@link com.google.appengine.spi.ServiceFactoryFactory} for details.
*
*
This package includes the utility ({@link com.google.appengine.spi.ServiceProvider
* ServiceProvider} for inserting the appropriate "service" entries into a jar file.
