--no-parent
Do not ever ascend to the parent directory when retrieving
recursively. This is a useful option, since it guarantees that
only the files below a certain hierarchy will be downloaded.
--relative
Follow relative links only. Useful for retrieving a specific home
page without any distractions, not even those from the same hosts.
hat mich daran erinnert, dass man mit relativen Links auch nach oben klettern kann.Beispiel eines relativen Links: "../relativer-link.htm").
