I think this is a great idea, but the web version of the document is surprisingly difficult to navigate and read. In fact, it's downright unpleasant. I understand why it is available as a hardcopy version through a publisher, but I wonder why the PDF isn't available for web use.
Hi. We're working on making the source code that was used to generate the web version and the ebook available on Github soon. With that anyone can easily generate a copy of the book in any format of their choice.
