extraction of text of graphical images from a PDF file. Text I could read and type it in again. Pictures I could photograph off my PC screen. It's completely moronic. It's Adobe. Plus some people at my college think it's protecting their documents well. They seem to believe that content which is made for education should under no circumstances leak to the outside - somebody could maybe learn something! It would be a disaster! It is obvious they're morons. This patch just proves my point." svn path=/nixpkgs/branches/stdenv-updates/; revision=9875
