| * Group arguments. |
| * By default, ArgumentParser groups command-line arguments |
| * into “positional arguments” and “optional arguments” |
| * when displaying help messages. When there is a better |
| * conceptual grouping of arguments than this default one, |
| * appropriate groups can be created using the addArgumentGroup() method |
| * |
| * This class inherited from [[ArgumentContainer]] |
