+Credentials object for OAuth 2.0.
+
+Credentials can be applied to an httplib2.Http object using the
+authorize() method, which then signs each request from that object
+with the OAuth 2.0 access token.  This set of credentials is for the
+use case where you have acquired an OAuth 2.0 access_token from
+another place such as a JavaScript client or another web
+application, and wish to use it from Python. Because only the
+access_token is present it can not be refreshed and will in time
+expire.
+
+AccessTokenCredentials objects may be safely pickled and unpickled.
+
+Usage:
+  credentials = AccessTokenCredentials('&lt;an access token&gt;',
+    'my-user-agent/1.0')
+  http = httplib2.Http()
+  http = credentials.authorize(http)
+
+Exceptions:
+  AccessTokenCredentialsExpired: raised when the access_token expires or is
+    revoked.
