There is a need to be able to remove one category tag from all pages that are in some other category or one of a set of categories. For instance [[category:people]] or [[category:biography]] on many wikis fills rapidly with pages that belong in one of the subcategories. There needs to be a way to automatically remove the parent category from any page that is in the subcategories, leaving behind only the pages that have no existing subcategorization and need to be sorted manually.
