, plus some of the discussion threaded from those posts. (Sorry, my stuff needs rewriting and updating but I'm not in the position to do it at present. If there's anything you would like to ask about please do. https://news.ycombinator.com/item?id=9809041 and https://news.ycombinator.com/item?id=10548477 touch on things that are a bit further down the line, but related—in particular, to the handling of "internal metadata" and files with a compound internal structure.)
