Having just done a formatting pass through it, I can confirm that it's truly a great piece of work.
I ordered it over 12 months ago and can't wait to get the printed copy in my hands but in the mean time, I've grabbed it and done some basic formatting to turn it into a PDF with a useful table of contents which I present for your download entertainment here.
My reading of the licensing is that this is perfectly OK, and indeed others have done it, but they are in strange non-metric formats and none that I've seen have a useful (clickable) table of contents.
(If I have done the wrong thing, please let me know ASAP and I'll remove it).
I did the formatting rather manually by copying the web pages into Apple's Pages. Must say, Pages is a superb word processor these days and I have no desire to run anything else again.
