+Session
+=======
+
+``openstack.session.Session`` is the class that maintains session layer
+similar to the OSI model session layer.  The session has a transport and
+an authenticator.  The transport is used by the session and authenticator
+for HTTP layer transport.  The authenticator is responsible for providing an
+authentication token and an endpoint to communicate with.
+
+Session object
+--------------
+
+.. class:: openstack.session.Session(transport, authenticator)
+
+   Create a new ``Session`` object with a transport and authenticator.
+
+   * transport -  Transport such as ``openstack.transport.Transport`` that
+     provides an HTTP request method.  The transport is also to be used by
+     the authenticator if needed.
+   * authenticator - An authenticator derived from
+     ``openstack.auth.base.BaseAuthenticator`` that provides get_token and
+     get_endpoint methods for the session.
+
+   All the other methods of the session accept the following parameters:
+
+   * service - a service filter for the authenticator to determine the
+     correct endpoint to use.
+   * authenticate - A flag that indicates if a token should be attached to the
+     request.  This parameter defaults to true.
+   * kwargs - The remaining arguments are passed to the transport request
+     method.
+
+   .. method:: head(url, service=service_filter, authenticate=True, **kwargs)
+
+      Perform an HTTP HEAD request.
+
+   .. method:: get(url, service=service_filter, authenticate=True, **kwargs)
+
+      Perform an HTTP GET request.
+
+   .. method:: post(url, service=service_filter, authenticate=True, **kwargs)
+
+      Perform an HTTP POST request.
+
+   .. method:: put(url, service=service_filter, authenticate=True, **kwargs)
+
+      Perform an HTTP PUT request.
+
+   .. method:: delete(url, service=service_filter, authenticate=True, **kwargs)
+
+      Perform an HTTP DELTE request.
+
+   .. method:: patch(url, service=service_filter, authenticate=True, **kwargs)
+
+      Perform an HTTP PATCH request.
+
+Examples
+--------
+
+The following examples use the example authenticator which takes the token
+and endpoint as arguments.
+
+Create a session
+~~~~~~~~~~~~~~~~
+
+Constructor::
+
+    from examples import authenticator
+    from openstack import session
+    from openstack import transport
+    xport = transport.Transport()
+    token = 'SecretToken'
+    endpoint = 'http://cloud.example.com:3333'
+    auther = authenticator.TestAuthenticator(token, endpoint)
+    sess = session.Session(xport, auther)
+
+HTTP GET
+~~~~~~~~
+
+Making a basic HTTP GET call::
+
+    containers = sess.get('/').json()
+
+The containers variable will contain a list of dict describing the containers.
+
+HTTP PUT
+~~~~~~~~
+
+Creating a new object::
+
+    objay_data = 'roland garros'
+    objay_len = len(objay_data)
+    headers = {"Content-Length": objay_len, "Content-Type": "text/plain"}
+    resp = sess.put('/pilots/french.txt', headers=headers, data=objay_data)
