with ``cl::CommaSeparated``, this modifier only makes sense with a `cl::list`_
option.
-.. _cl::DefaultOption:
-
-* The **cl::DefaultOption** modifier is used to specify that the option is a
- default that can be overridden by application specific parsers. For example,
- the ``-help`` alias, ``-h``, is registered this way, so it can be overridden
- by applications that need to use the ``-h`` option for another purpose,
- either as a regular option or an alias for another option.
