---------------------------------------------------------
[~ebourg], I don't quite understand your suggestion here. If I set the option
group as required then it will require to have a --help or --version but that
doesn't translate to "if --help or --version are provided, skip the required
options list outside this option group".
Here is a practical example:
{noformat}
java -jar app.jar --help
Missing required options: s, t
usage: server-migration [-e <environment file>] [-h] [-i <true/false>] -s
<source> -t <target>
-e,--environment <environment file> env
-h,--help help
-i,--interactive <true/false> int
-s,--source <source> src
-t,--target <target> tgt
{noformat}
If I provide -s and -t then all is fine and help is printed as expected. If I
don't provide any options, than this message is correct, s and t are indeed
missing.

> 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.
