How to use the tockloader._version.__version__ function in tockloader

logging.basicConfig(style='{', format='[{levelname:<7}] {message}', level=logging.DEBUG)
	# Add a custom status level for logging what tockloader is doing.
	logging.addLevelName(25, 'STATUS')
	logging.Logger.status = functools.partialmethod(logging.Logger.log, 25)
	logging.status = functools.partial(logging.log, 25)

	# Create a common parent parser for arguments shared by all subparsers. In
	# practice there are very few of these since tockloader supports a range of
	# operations.
	parent = argparse.ArgumentParser(add_help=False)
	parent.add_argument('--debug',
		action='store_true',
		help='Print additional debugging information')
	parent.add_argument('--version',
		action='version',
		version=__version__,
		help='Print Tockloader version and exit')

	# Get the list of arguments before any command
	before_command_args = parent.parse_known_args()

	# The top-level parser object
	parser = argparse.ArgumentParser(parents=[parent])

	# Parser for all app related commands
	parent_apps = argparse.ArgumentParser(add_help=False)
	parent_apps.add_argument('--app-address', '-a',
		help='Address where apps are located',
		type=lambda x: int(x, 0))
	parent_apps.add_argument('--force',
		help='Allow apps on boards that are not listed as compatible',
		action='store_true')

def command_info (args):
	tock_loader = TockLoader(args)
	tock_loader.open()

	print('tockloader version: {}'.format(__version__))
	logging.status('Showing all properties of the board...')
	tock_loader.info()
