    Flame can be used with a shade or openstack sdk instance, and options can
    be passed as option kwargs.

    ex:

        from flameclient.session import get_shade
        from flameclient import flame

        auth_kwargs = {
            'auth_type': u'password',
            'auth_url': 'https://your_cloud_identity_url/v2.0',
            'interface': 'public',
            'password': 'YourPassword',
            'project_id': 'YourProjectID',
            'project_name': 'YourProjectName',
            'region_name': 'region_one',
            'username': 'YourUserName'
        }

        cloud = get_shade(**auth_kwargs)

    Or instead of kwargs if you want to use environment variables:

        cloud = get_shade(load_envvars=True)

    Then:

        generator = flame.TemplateGenerator(
            connection=cloud,
            options=dict(
                include_constraint=True,
                extract_ports=True,
                generate_adoption_data=True,
                no_threads=True)
        )

        generator.extract_data()
        print(generator.heat_template_and_data())

    Passing a shade or openstack sdk instance and option kwargs allows you to
    integrate shade in other projects.
