This is especially obnoxious for books that are already DRM-free. For example, one can presently buy a Tor (the publisher, not the onion router) book from the Kindle store, download the azw3 file, use a tool like KindleUnpacker [0] to more or less losslessly convert it to ePub, and read it anywhere.

And of wanting an output directory instead of a filename. And of leaving a whole pile of unnecessary temporary files around. And of forcing you to look through the temporary crap to even find the output. Oh well; the actual output is excellent.
