I wouldn't bother with detection. setup.exe is a gui, it's fine for it
to show help as a gui.

What is needed is this:
The current libgetopt call to show the parameter help should become a
convenience call over a lower interface.

That interface should:
* Provide a const interator to all the options in the optionset.

That will let setup iterate over the options, extracting the help text
and placing into a GUI text area (or a combobox etc etc).

This is also on my TODO, and why I haven't applied your trivial 'add
help' option to setup - because it will need to be changed no matter
what.
