# this hack normalize 'show' and 'version' subcommands 'type_'
# attribute with other type_ sensitive subcommands. Without this
# hack, the next statement (i.e. "if args.type_ is None:") fails with
# "AttributeError: 'Namespace' object has no attribute 'type_'".
#
# notes
# - show and version subcommands type_ attribute is already strictly
# defined by the parameter argument (e.g. dataset identifier, file
# identifier, etc..), so we dont want the user to also be able to
# set type_ attribute using options. This is why type_ group is not
# present for show and version subcommands (see subparser module
# for details).
# - another way to normalize is to use "parser.set_defaults(type_=None)"
