    from `botocore` as well as important data such as configuration
    information and credentials into a single, easy-to-use object.

        file associated with this session.

        :type session_vars: dict
        :param session_vars: A dictionary that is used to override some or all
            of the environment variables associated with this session.  The
            key/value pairs defined in this dictionary will override the
            corresponding variables defined in ``SESSION_VARIABLES``.

        :type event_hooks: BaseEventHooks
        :param event_hooks: The event hooks object to use. If one is not

        :type include_builtin_handlers: bool

            automatically register builtin handlers.

        :param profile: The name of the profile to use for this
            session.  Note that the profile can only be set when
            the session is created.

z0Session._get_config_variable_with_custom_methodscCst�d||�||j|<dS)a�Set a configuration variable to a specific value.

        By using this method, you can override the normal lookup
        process used in ``get_config_variable`` by explicitly setting
        a value.  Subsequent calls to ``get_config_variable`` will
        use the ``value``.  This gives you per-session specific
        configuration values.

        ::
            >>> # Assume logical name 'foo' maps to env var 'FOO'
            >>> os.environ['FOO'] = 'myvalue'
            >>> s.get_config_variable('foo')
            'myvalue'
            >>> s.set_config_variable('foo', 'othervalue')
            >>> s.get_config_variable('foo')
            'othervalue'

        :type logical_name: str
        :param logical_name: The logical name of the session variable
            you want to set.  These are the keys in ``SESSION_VARIABLES``.
        :param value: The value to associate with the config variable.

        Returns the config values from the config file scoped to the current
        profile.

        The configuration data is loaded **only** from the config file.
        It does not resolve variables based on different locations
        (e.g. first from the session instance, then from environment
        variables, then from the config file).  If you want this lookup
        behavior, use the ``get_config_variable`` method instead.

        Note that this configuration is specific to a single profile (the
        ``profile`` session variable).

        If the ``profile`` session variable is set and the profile does
        not exist in the config file, a ``ProfileNotFound`` exception
        will be raised.

        :param handler: The callback to unregister.

        :type unique_id: str
        :param unique_id: A unique identifier identifying the callback
            to unregister.  You can provide either the handler or the
            unique_id, you do not have to provide both.

        :param unique_id_uses_count: boolean
        :param unique_id_uses_count: Specifies if the event should maintain
            a count when a ``unique_id`` is registered and unregisted. The
            event can only be completely unregistered once every ``register``
            call using the ``unique_id`` has been matched by an ``unregister``
            call. If the ``unique_id`` is specified, subsequent
            ``unregister`` calls must use the same value for
            ``unique_id_uses_count`` as the ``register`` call that first
            registered the event.

        :raises ValueError: If the call to ``unregister`` uses ``unique_id``
            but the value for ``unique_id_uses_count`` differs from the
            ``unique_id_uses_count`` value declared by the very first
            ``register`` call for that ``unique_id``.

Create a botocore client.

        :type service_name: string
        :param service_name: The name of the service for which a client will
            be created.  You can use the ``Session.get_available_services()``
            method to get a list of all available service names.

        :type region_name: string
        :param region_name: The name of the region associated with the client.
            A client is associated with a single region.

        :type api_version: string
        :param api_version: The API version to use.  By default, botocore will
            use the latest API version when creating a client.  You only need
            to specify this parameter if you want to use a previous API version
            of the client.

        :type use_ssl: boolean
        :param use_ssl: Whether or not to use SSL.  By default, SSL is used.
            Note that not all services support non-ssl connections.

        :type verify: boolean/string
        :param verify: Whether or not to verify SSL certificates.
            By default SSL certificates are verified.  You can provide the
            following values:

            * False - do not validate SSL certificates.  SSL will still be
              used (unless use_ssl is False), but SSL certificates
              will not be verified.
            * path/to/cert/bundle.pem - A filename of the CA cert bundle to
              uses.  You can specify this argument if you want to use a
              different CA cert bundle than the one used by botocore.

        :type endpoint_url: string
        :param endpoint_url: The complete URL to use for the constructed
            client.  Normally, botocore will automatically construct the
            appropriate URL to use when communicating with a service.  You can
            specify a complete URL (including the "http/https" scheme) to
            override this behavior.  If this value is provided, then
            ``use_ssl`` is ignored.

        :type aws_access_key_id: string
        :param aws_access_key_id: The access key to use when creating
            the client.  This is entirely optional, and if not provided,
            the credentials configured for the session will automatically
            be used.  You only need to provide this argument if you want
            to override the credentials used for this specific client.

        :type aws_secret_access_key: string
        :param aws_secret_access_key: The secret key to use when creating
            the client.  Same semantics as aws_access_key_id above.

        :type aws_session_token: string
        :param aws_session_token: The session token to use when creating
            the client.  Same semantics as aws_access_key_id above.

        :type config: botocore.client.Config
        :param config: Advanced client configuration options. If a value
            is specified in the client config, its value will take precedence
            over environment variables and configuration values, but not over
            a value passed explicitly to the method. If a default config
            object is set on the session, the config object used when creating
            the client will be the result of calling ``merge()`` on the
            default config with the config provided to this call.

        :type aws_account_id: string
        :param aws_account_id: The account id to use when creating
            the client.  Same semantics as aws_access_key_id above.

        :rtype: botocore.client.BaseClient
        :return: A botocore client instance

    This class can be used instead of
    :class:`botocore.configprovider.ConfigChainFactory` to make it honor the
    methods argument to get_config_variable. This class can be used to filter
    out providers that are not in the methods tuple when creating a new config
    chain.

        This config chain factory will omit any providers not in the methods
        tuple provided at initialization. For example if given the tuple
        ('instance', 'config',) it will not inject the environment provider
        into the standard config chain. This lets the botocore session support
        the custom ``methods`` argument for all the default botocore config
        variables when calling ``get_config_variable``.
