of course it's still a bilevel image rather than greyscale, so you mess
up a lot of diagrams and images within the documentation, and go a long
way toward ruining the chances of someone running a useful OCR scan over
the data at some future point :-(

I can't remember exactly what documentation's being discussed; bilevel's
great for documents that are still pretty common but if it's something
rare then it doesn't do much on the preservation front :-(
