```
    Returns a valid ArgGroupSpec instance.
  - exclusive
```
public boolean exclusive()
```
    Returns whether this is a mutually exclusive group; true by default. If false, this is a co-occurring group. Ignored if validate() is false.

```
public CommandLine.Range multiplicity()
```
    Returns the multiplicity of this group: how many occurrences it may have on the command line; "0..1" (optional) by default. A group can be made required by specifying a multiplicity of "1". For a group of mutually exclusive arguments, being required means that one of the arguments in the group must appear on the command line, or a MissingParameterException is thrown. For a group of co-occurring arguments, being required means that all arguments in the group must appear on the command line. Ignored if validate() is false.
