> One use case of DistCp is to sync two directories. Currently, DistCp has an
> -update option for overwriting dst files if src is different from dst.
> However, it is not enough for sync. If there are some files in dst but not
> exist in src, there is no easy way to delete them. We should add a new
> option, say -delete, so that DistCp will delete the non-existing in dst.
