I've got a bunch of PDF files that contain two "real" pages to a single PDF page; I'd like to chop these in half and put each half on a separate page. Essentially, I need something that does the exact opposite of
psnup). How can this feat be achieved?
Platform is Linux, open source preferred; as I've got a great pile of these to do something that can be scripted (as opposed to a GUI) would be nice, so I can just give it a list of them and have it chew away.
A pre-existing script isn't the only option, either; if there's sample code to manipulate PDFs in similar ways with a third-party library, I can probably hack it into doing what I want.
