dd| dd dS )a Supports args of the argparse.ArgumentParser constructor
as **kwargs, as well as the following additional args.
Additional Args:
add_config_file_help: Whether to add a description of config file
syntax to the help message.
add_env_var_help: Whether to add something to the help message for
args that can be set through environment variables.
auto_env_var_prefix: If set to a string instead of None, all config-
file-settable options will become also settable via environment
variables whose names are this prefix followed by the config
file key, all in upper case. (eg. setting this to "foo_" will
allow an arg like "--my-arg" to also be set via the FOO_MY_ARG
environment variable)
default_config_files: When specified, this list of config files will
be parsed in order, with the values from each config file
taking precedence over pervious ones. This allows an application
to look for config files in multiple standard locations such as
the install directory, home directory, and current directory.
Also, shell * syntax can be used to specify all conf files in a
directory. For exmaple:
["/etc/conf/app_config.ini",
"/etc/conf/conf-enabled/*.ini",
"~/.my_app_config.ini",
"./app_config.txt"]
ignore_unknown_config_file_keys: If true, settings that are found
in a config file but don't correspond to any defined
configargparse args will be ignored. If false, they will be
processed and appended to the commandline like other args, and
can be retrieved using parse_known_args() instead of parse_args()
config_file_parser_class: configargparse.ConfigFileParser subclass
which determines the config file format. configargparse comes
with DefaultConfigFileParser and YAMLConfigFileParser.
args_for_setting_config_path: A list of one or more command line
args to be used for specifying the config file path
(eg. ["-c", "--config-file"]). Default: []
config_arg_is_required: When args_for_setting_config_path is set,
set this to True to always require users to provide a config path.
config_arg_help_message: the help message to use for the
args listed in args_for_setting_config_path.
args_for_writing_out_config_file: A list of one or more command line
args to use for specifying a config file output path. If
provided, these args cause configargparse to write out a config
file with settings based on the other provided commandline args,
environment variants and defaults, and then to exit.
(eg. ["-w", "--write-out-config-file"]). Default: []
write_out_config_file_arg_help_message: The help message to use for
the args in args_for_writing_out_config_file.

This method supports the same args as ArgumentParser.add_argument(..)
as well as the additional args below.
Additional Args:
env_var: If set, the value of this environment variable will override
any config file or default values for this arg (but can itself
be overriden on the commandline). Also, if auto_env_var_prefix is
set in the constructor, this env var name will be used instead of
the automatic name.
is_config_file_arg: If True, this arg is treated as a config file path
This provides an alternative way to specify config files in place of
the ArgumentParser(fromfile_prefix_chars=..) mechanism.
Default: False
is_write_out_config_file_arg: If True, this arg will be treated as a
config file path, and, when it is specified, will cause
configargparse to write all current commandline args to this file
as config options and then exit.
Default: False
