[arch-general] definition of "orphan"

Hi, in the arch world I see two different definition of an "orphan". The pacman manpage says: orphans - packages that were installed as dependencies  but are no longer required by any installed package. For the AUR the definition of an "orphan" is  If all maintainers of an AUR package disown it, it will  become an "orphaned" package. (https://wiki.archlinux.org/index.php/AUR_submission_guidelines#Maintaining_p... ) This is confusing. Would it make sense to change the wording so that it is not ambiguous anymore. Matthias
