Emmanuel Bourg commented on CLI-179:
------------------------------------

Actually there is a solution with the current API. You can create a group w=
ith --version, --help and your options, and mark it as required. The parser=
 will check if one of the options is present.

> it is currently impossible to have options like "help" or "version" if we=
 also have some required options. The parsing results in an error "Missing =
parameters".
> But for an "help" or "version" option, it would be usefull to display the=
 wanted information, even if required options are not set.
