+"""Transport - Asynchronous HTTP client library support.
+
+:mod:`google.auth.aio` is designed to work with various asynchronous client libraries such
+as aiohttp. In order to work across these libraries with different
+interfaces some abstraction is needed.
+
+This module provides two interfaces that are implemented by transport adapters
+to support HTTP libraries. :class:`Request` defines the interface expected by
+:mod:`google.auth` to make asynchronous requests. :class:`Response` defines the interface
+for the return value of :class:`Request`.
