Simple command line framework inspired by nox.
Argument parsing is handled by argparse. Each function annotated with an instance of this class becomes a subcommand.
Options are shared across all commands, and are defined by providing kwargs when creating an instance of this class.
Options are only defined for commands which have a matching parameter.
The name of each kwarg is the option name, which will be prefixed with `--` and with underscores converted to dashes.
The value of each kwarg is passed as kwargs to ArgumentParser.add_argument. Passing None results in an internal only parameter.
The following custom kwargs are recognized and are not passed to add_argument:
name - Override the positional argument (option) passed to add_argument.
exclusive - Put the argument in an exclusive group of the given name.
