def cloudant(user, passwd, **kwargs):
    Provides a context manager to create a Cloudant session and
    provide access to databases, docs etc.
    :param str user: Username used to connect to Cloudant.
    :param str passwd: Authentication token used to connect to Cloudant.
    :param str account: The Cloudant account name.  If the account parameter
        is present, it will be used to construct the Cloudant service URL.
    :param str url: If the account is not present and the url parameter is
        present then it will be used to set the Cloudant service URL.  The
        url must be a fully qualified http/https URL.
    :param str x_cloudant_user: Override the X-Cloudant-User setting used to
        authenticate. This is needed to authenticate on one's behalf,
        eg with an admin account.  This parameter must be accompanied
        by the url parameter.  If the url parameter is omitted then
        the x_cloudant_user parameter setting is ignored.
    :param str encoder: Optional json Encoder object used to encode
        documents for storage. Defaults to json.JSONEncoder.
    For example:
    .. code-block:: python
        # cloudant context manager
        from cloudant import cloudant
        with cloudant(USERNAME, PASSWORD, account=ACCOUNT_NAME) as client:
            # Context handles connect() and disconnect() for you.
            # Perform library operations within this context.  Such as:
            print client.all_dbs()
            # ...
    cloudant_session = Cloudant(user, passwd, **kwargs)
    cloudant_session.connect()
    yield cloudant_session
    cloudant_session.disconnect()
@contextlib.contextmanager
def cloudant_iam(account_name, api_key, **kwargs):
    Provides a context manager to create a Cloudant session using IAM
    authentication and provide access to databases, docs etc.
    :param account_name: Cloudant account name.
    :param api_key: IAM authentication API key.
    For example:
    .. code-block:: python
        # cloudant context manager
        from cloudant import cloudant_iam
        with cloudant_iam(ACCOUNT_NAME, API_KEY) as client:
            # Context handles connect() and disconnect() for you.
            # Perform library operations within this context.  Such as:
            print client.all_dbs()
            # ...
    cloudant_session = Cloudant.iam(account_name, api_key, **kwargs)
    cloudant_session.connect()
    yield cloudant_session
    cloudant_session.disconnect()
@contextlib.contextmanager
def cloudant_bluemix(vcap_services, instance_name=None, **kwargs):
    Provides a context manager to create a Cloudant session and provide access
    to databases, docs etc.
    :param vcap_services: VCAP_SERVICES environment variable
    :type vcap_services: dict or str
    :param str instance_name: Optional Bluemix instance name. Only required if
        multiple Cloudant instances are available.
    :param str encoder: Optional json Encoder object used to encode
        documents for storage. Defaults to json.JSONEncoder.
    Loads all configuration from the specified VCAP_SERVICES Cloud Foundry
    environment variable. The VCAP_SERVICES variable contains connection
    information to access a service instance. For example:
    .. code-block:: json
            "VCAP_SERVICES": {
                "cloudantNoSQLDB": [
                        "credentials": {
                            "username": "example",
                            "password": "xxxxxxx",
                            "host": "example.cloudant.com",
                            "url": "https://example:xxxxxxx@example.cloudant.com"
                        "syslog_drain_url": null,
                        "label": "cloudantNoSQLDB",
                        "provider": null,
                        "plan": "Lite",
                        "name": "Cloudant NoSQL DB"
