Well, I think it doesn't have to be true: there can be some options
like e.g. '-n' / '--dry-run' that are common to all subcommands, and
in my opinion they could come before subcommand name.

But if restriction that subcommand name must be first simplifies code,
then let's do it this way.


I agree that subcommands are and must be mutually exclusive --
otherwise they better be implemented as options, not subcommands.
