Below you'll find the initial, proposed table of contents for the book. Note that these contents are subject to change.
The version of the book you would buy today includes all the sections highlighted in green. The book is currently approximately 360 pages in PDF format. (I've numbered the current version of the book 0.61).
People that have purchased the book can always download the latest version. I expect the book to be complete around the end of May 2013 (or so). If you have any questions, see the FAQ page.
