Is there any way to to tell rinari-console to run in sandbox mode? M-x rinari-console seems to be the only comand, and I don't know how to pass the ---sandbox flag to it. This should be simple, but my google-fu is completely failing.
I'm not a Ruby developer, but it looks like you can make Rinari prompt you for arguments with a prefix argument: C-u M-x rinari-console RET.
