I have two pdfs, A.pdf and B.pdf, each of which has some bookmarks (perhaps added by jpdfbookmarks). I'd like to concatenate them into one big file, AB.pdf. So I tried one of my favorite tools, pdftk:
pdftk A.pdf B.pdf cat output AB.pdf
But then AB.pdf doesn't have any bookmarks! Is there some way to concatenate pdfs in such a way that you retain the bookmarks? I prefer a Free, or at least free, command-line tool that will work on linux.
