+This helps loading http_pb2 and annotations_pb2.
+Without this, the Python importer will not be able to process the lines:
+from google.api import http_pb2 or
+from google.api import annotations_pb2
+(Without importing these, the protobuf loader will not recognize http options
+in the protobuf definitions.)
