-- this file contains a few enhancements to the normal book and
-- paper functionality. it allows authors to disavow their books,
-- making them appear as by an "unknown author", by smudging out
-- the byline with black dye. it also allows written books to be
-- soaked in a bucket of water to wash out the ink and return
-- them to a virginal, unwritten state. finally, it makes it so
-- that when a book (or any owned item, for that matter) is
-- copied, the owner of the new copy is set to the user who
-- copied it, allowing users to collaborate on books.
