| * <p>Mainly useful when creating complex command based CLI interfaces, |
| * where several commands can share a set of arguments, but using |
| * object inheritance is not enough, due to no-multiple-inheritance |
| * restriction. Using {@link ParametersDelegate} any number of |
| * command sets can be shared by using composition pattern.</p> |
