-Configuration options which may be set on the command line or in config files.
-
-The schema for each option is defined using the Opt sub-classes, e.g.:
-
-::
-
-    common_opts = [
-        cfg.StrOpt('bind_host',
-                   default='0.0.0.0',
-                   help='IP address to listen on'),
-        cfg.IntOpt('bind_port',
-                   default=9292,
-                   help='Port number to listen on')
-    ]
-
-Options can be strings, integers, floats, booleans, lists or 'multi strings'::
-
-    enabled_apis_opt = cfg.ListOpt('enabled_apis',
-                                   default=['ec2', 'osapi_compute'],
-                                   help='List of APIs to enable by default')
-
-    DEFAULT_EXTENSIONS = [
-        'nova.api.openstack.compute.contrib.standard_extensions'
-    ]
-    osapi_compute_extension_opt = cfg.MultiStrOpt('osapi_compute_extension',
-                                                  default=DEFAULT_EXTENSIONS)
-
-Option schemas are registered with the config manager at runtime, but before
-the option is referenced::
-
-    class ExtensionManager(object):
-
-        enabled_apis_opt = cfg.ListOpt(...)
-
-        def __init__(self, conf):
-            self.conf = conf
-            self.conf.register_opt(enabled_apis_opt)
-            ...
-
-        def _load_extensions(self):
-            for ext_factory in self.conf.osapi_compute_extension:
-                ....
-
-A common usage pattern is for each option schema to be defined in the module or
-class which uses the option::
-
-    opts = ...
-
-    def add_common_opts(conf):
-        conf.register_opts(opts)
-
-    def get_bind_host(conf):
-        return conf.bind_host
-
-    def get_bind_port(conf):
-        return conf.bind_port
-
-An option may optionally be made available via the command line. Such options
-must registered with the config manager before the command line is parsed (for
-the purposes of --help and CLI arg validation)::
-
-    cli_opts = [
-        cfg.BoolOpt('verbose',
-                    short='v',
-                    default=False,
-                    help='Print more verbose output'),
-        cfg.BoolOpt('debug',
-                    short='d',
-                    default=False,
-                    help='Print debugging output'),
-    ]
-
-    def add_common_opts(conf):
-        conf.register_cli_opts(cli_opts)
-
-The config manager has two CLI options defined by default, --config-file
-and --config-dir::
-
-    class ConfigOpts(object):
-
-        def __call__(self, ...):
-
-            opts = [
-                MultiStrOpt('config-file',
-                        ...),
-                StrOpt('config-dir',
-                       ...),
-            ]
-
-            self.register_cli_opts(opts)
-
-Option values are parsed from any supplied config files using
-openstack.common.iniparser. If none are specified, a default set is used
-e.g. glance-api.conf and glance-common.conf::
-
-    glance-api.conf:
-      [DEFAULT]
-      bind_port = 9292
-
-    glance-common.conf:
-      [DEFAULT]
-      bind_host = 0.0.0.0
-
-Option values in config files override those on the command line. Config files
-are parsed in order, with values in later files overriding those in earlier
-files.
-
-The parsing of CLI args and config files is initiated by invoking the config
-manager e.g.::
-
-    conf = ConfigOpts()
-    conf.register_opt(BoolOpt('verbose', ...))
-    conf(sys.argv[1:])
-    if conf.verbose:
-        ...
-
-Options can be registered as belonging to a group::
-
-    rabbit_group = cfg.OptGroup(name='rabbit',
-                                title='RabbitMQ options')
-
-    rabbit_host_opt = cfg.StrOpt('host',
-                                 default='localhost',
-                                 help='IP/hostname to listen on'),
-    rabbit_port_opt = cfg.IntOpt('port',
-                                 default=5672,
-                                 help='Port number to listen on')
-
-    def register_rabbit_opts(conf):
-        conf.register_group(rabbit_group)
-        # options can be registered under a group in either of these ways:
-        conf.register_opt(rabbit_host_opt, group=rabbit_group)
-        conf.register_opt(rabbit_port_opt, group='rabbit')
-
-If it no group attributes are required other than the group name, the group
-need not be explicitly registered e.g.
-
-    def register_rabbit_opts(conf):
-        # The group will automatically be created, equivalent calling::
-        #   conf.register_group(OptGroup(name='rabbit'))
-        conf.register_opt(rabbit_port_opt, group='rabbit')
-
-If no group is specified, options belong to the 'DEFAULT' section of config
-files::
-
-    glance-api.conf:
-      [DEFAULT]
-      bind_port = 9292
-      ...
-
-      [rabbit]
-      host = localhost
-      port = 5672
-      use_ssl = False
-      userid = guest
-      password = guest
-      virtual_host = /
-
-Command-line options in a group are automatically prefixed with the
-group name::
-
-    --rabbit-host localhost --rabbit-port 9999
-
-Option values in the default group are referenced as attributes/properties on
-the config manager; groups are also attributes on the config manager, with
-attributes for each of the options associated with the group::
-
-    server.start(app, conf.bind_port, conf.bind_host, conf)
-
-    self.connection = kombu.connection.BrokerConnection(
-        hostname=conf.rabbit.host,
-        port=conf.rabbit.port,
-        ...)
-
-Option values may reference other values using PEP 292 string substitution::
-
-    opts = [
-        cfg.StrOpt('state_path',
-                   default=os.path.join(os.path.dirname(__file__), '../'),
-                   help='Top-level directory for maintaining nova state'),
-        cfg.StrOpt('sqlite_db',
-                   default='nova.sqlite',
-                   help='file name for sqlite'),
-        cfg.StrOpt('sql_connection',
-                   default='sqlite:///$state_path/$sqlite_db',
-                   help='connection string for sql database'),
-    ]
-
-Note that interpolation can be avoided by using '$$'.
-
-Options may be declared as required so that an error is raised if the user
-does not supply a value for the option.
-
-Options may be declared as secret so that their values are not leaked into
-log files::
-
-     opts = [
-        cfg.StrOpt('s3_store_access_key', secret=True),
-        cfg.StrOpt('s3_store_secret_key', secret=True),
-        ...
-     ]
-
-This module also contains a global instance of the ConfigOpts class
-in order to support a common usage pattern in OpenStack::
-
-    from tempest.openstack.common import cfg
-
-    opts = [
-        cfg.StrOpt('bind_host', default='0.0.0.0'),
-        cfg.IntOpt('bind_port', default=9292),
-    ]
-
-    CONF = cfg.CONF
-    CONF.register_opts(opts)
-
-    def start(server, app):
-        server.start(app, CONF.bind_port, CONF.bind_host)
-
-Positional command line arguments are supported via a 'positional' Opt
-constructor argument::
-
-    >>> conf = ConfigOpts()
-    >>> conf.register_cli_opt(MultiStrOpt('bar', positional=True))
-    True
-    >>> conf(['a', 'b'])
-    >>> conf.bar
-    ['a', 'b']
-
-It is also possible to use argparse "sub-parsers" to parse additional
-command line arguments using the SubCommandOpt class:
-
-    >>> def add_parsers(subparsers):
-    ...     list_action = subparsers.add_parser('list')
-    ...     list_action.add_argument('id')
-    ...
-    >>> conf = ConfigOpts()
-    >>> conf.register_cli_opt(SubCommandOpt('action', handler=add_parsers))
-    True
-    >>> conf(args=['list', '10'])
-    >>> conf.action.name, conf.action.id
-    ('list', '10')
