+/** internal
+ * class ArgumentGroup
+ *
+ * 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]]
