+"""The App Engine Transport Adapter for requests.

+.. versionadded:: 0.6.0
+
+This requires a version of requests >= 2.10.0 and Python 2.
+
+There are two ways to use this library:
+
+#. If you're using requests directly, you can use code like:
+
+   .. code-block:: python
+
+       >>> import requests
+       >>> import ssl
+       >>> import requests.packages.urllib3.contrib.appengine as ul_appengine
+       >>> from requests_toolbelt.adapters import appengine
+       >>> s = requests.Session()
+       >>> if ul_appengine.is_appengine_sandbox():
+       ...    s.mount('http://', appengine.AppEngineAdapter())
+       ...    s.mount('https://', appengine.AppEngineAdapter())
+
+#. If you depend on external libraries which use requests, you can use code
+   like:
+
+   .. code-block:: python
+
+       >>> from requests_toolbelt.adapters import appengine
+       >>> appengine.monkeypatch()
+
+which will ensure all requests.Session objects use AppEngineAdapter properly.
+
+You are also able to :ref:`disable certificate validation <insecure_appengine>`
+when monkey-patching.

+"""
+This module provides the API for ``requests_toolbelt.threaded``.
+
+The module provides a clean and simple API for making requests via a thread
+pool. The thread pool will use sessions for increased performance.
+
+A simple use-case is:
+
+.. code-block:: python
+
+    from requests_toolbelt import threaded
+
+    urls_to_get = [{
+        'url': 'https://api.github.com/users/sigmavirus24',
+        'method': 'GET',
+    }, {
+        'url': 'https://api.github.com/repos/requests/toolbelt',
+        'method': 'GET',
+    }, {
+        'url': 'https://google.com',
+        'method': 'GET',
+    }]
+    responses, errors = threaded.map(urls_to_get)
+
+By default, the threaded submodule will detect the number of CPUs your
+computer has and use that if no other number of processes is selected. To
+change this, always use the keyword argument ``num_processes``. Using the
+above example, we would expand it like so:
+
+.. code-block:: python
+
+    responses, errors = threaded.map(urls_to_get, num_processes=10)
+
+You can also customize how a :class:`requests.Session` is initialized by
+creating a callback function:
+
+.. code-block:: python
+
+    from requests_toolbelt import user_agent
+
+    def initialize_session(session):
+        session.headers['User-Agent'] = user_agent('my-scraper', '0.1')
+        session.headers['Accept'] = 'application/json'
+
+    responses, errors = threaded.map(urls_to_get,
+                                     initializer=initialize_session)
+
+.. autofunction:: requests_toolbelt.threaded.map
+
+Inspiration is blatantly drawn from the standard library's multiprocessing
+library. See the following references:
+
+- multiprocessing's `pool source`_
+
+- map and map_async `inspiration`_
+
+.. _pool source:
+    https://hg.python.org/cpython/file/8ef4f75a8018/Lib/multiprocessing/pool.py
