Query: Good book but no documentation!!!

I thought the book was quite good but was disappointed that there was no documentation on the website that was promised in the book. Not only that, but the book website had broken links and hasn't been updated in months and our requests have fallen on deaf ears... I've waited a year to write this review as I didn't want to jump to conclusions. So while I found the book an informative read I only rated it one star as I would not have bought the book if the documentation was never going to be made by the author. He has now asked the community to provide the documentation through the website...It also bring up questions as to whether the documentation was ever used for actual projects or just to sell books. From the Book's website it seems to be the latter.
