| which doesn't allow '-' in name). This function is to allow tools to have, for time being, |
| parameters which can't be parsed using <code>Option</code>. |
| Overrides should consume all valid legacy arguments. If the param 'args' is not empty on |
| return, it means there were invalid options, in which case we'll exit from the tool. |
