@DiapDealer -- any more updates to the PI?
It's been a big time saver; I had a couple of really ugly epubs that I was able to clean in a lot less time than it used to take
I don't know why people think it's necessary to exactly duplicate a dead tree version of a book. Most of the very subtle format differences are invisible in my reader.
I spend most of the time removing multiple nested <span> tags, and in a recent cleanup, every paragraph was in it's own <div>. I've gotten used to the 4 or 5 TOC files that get added because the book has been Calibre-converted multiple times.
Thanks again for the PI
