Subject: [PATCH] neue SL::DB::Part Methode used_in_record.
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Die Prüfung auf orphaned ist viel strenger, und sollte für z.B. Löschen
verwendet werden, während used_in_record nur prüft, ob der Artikel in
Belegen vorkommt.
