Removing copy protection from PDFs

This is often a work issue–eg with stuff forwarded to attorneys by IT-challenged clients–but also arises when archives digitalise stuff which is way out of copyright but which they still protect from private fiddling around, whether because of a lack of sophistication in their systems or because of some mad bureaucrat stuck up in the attic. This works for me and also produces decent text dumps from bitmaps. Just don’t do anything illegal. Prison food is the first to suffer in a recession.
