        we point at with the binsha of this instance.

            modules as well.

        :param to_latest_revision: if True, the submodule's sha will be ignored during checkout.
            Instead, the remote will be fetched, and the local tracking branch updated.
            This only works if we have a local tracking branch, which is the case
            if the remote repository had a master branch, or of the 'branch' option
            was specified for this submodule and the branch existed remotely

        :param force:
            If True, we may reset heads even if the repository in question is dirty. Additinoally we will be allowed
            to set a tracking branch which is ahead of its remote branch back into the past or the location of the
            remote branch. This will essentially 'forget' commits.
            If False, local tracking branches that are in the future of their respective remote branches will simply
            not be moved.
        :param keep_going: if True, we will ignore but log all errors, and keep going recursively.
            Unless dry_run is set as well, keep_going could cause subsequent / inherited errors you wouldn't see
            otherwise.
            In conjunction with dry_run, it can be useful to anticipate all errors when updating submodules
        :param env: Optional dictionary containing the desired environment variables.
            Note: Provided variables will be used to update the execution
            environment for `git`. If some variable is not specified in `env`
            and is defined in `os.environ`, value from `os.environ` will be used.
            If you want to unset some variable, consider providing empty string
            as its value.
        :param clone_multi_options:  list of Clone options. Please see ``git.repo.base.Repo.clone``
            for details. Only take effect with `init` option.
        :param allow_unsafe_protocols: Allow unsafe protocols to be used, like ext
