Render unto Proprietary...

Render unto proprietary formats (Kindle) that which is proprietary (a novel) and with proprietary tools (Kindlegen.) Calibre, with their obsession with reverse-engineering the kindle formats, can't produce output that KDP will accept without mangling, but they continue to shriek that plugins to use kindlegen aren't needed. Pedantic behavior like that, I can live without. Just have to redo the book in Jutoh. What book, you ask? Well, a little bird tells me that Looking Glass may be back on the market in the foreseeable future.
