I think I could add a hook for -h, that would first print help for the multiruby script and then keep running for the used interpreter. So something like
$ ruby -h
This is Fedora's multiruby executable. You can blah blah blah...
Currently available runtimes: _mri_ (default), _jruby_

Selected: _mri_

<actual help for MRI>


I think this shouldn't affect the performance and it shouldn't damage user experience.
Does that sound sane?
