      # problem... inner command could have a different category but we want this to be a runtime error...
      # So I guess we should use our error class anyways but override its methods...
      # Or do we want to let the inner category reign? Issue with that is the subcommand could have the same
      # name as an input and collide (unlikely but possible.)
      # So what to do? Wrapper error? Maybe introduce a sub command category for the wrapper?
      # other solution instead.... add a runtime_path to Error
      add_subcommand_error(subcommand, error)

#subcommand? ⇒ Boolean

Returns:
