Revisions. The book will be going for a reprint later this year (2017). It will have a few minor revisions (reflecting new research). This site will continue to contain the "first edition" content until the second edition is sent to press, when the minor revisions will be applied and the downloadable copy will also be changed.
In the meantime, notes regarding revisions will be found here.

The new edition of the book is now ready in web form here.
(Though there may still be some minor tweaks and extra research links added.)

Your help is requested. If you find anything you think is a mistake, please let us know.

This book is FREE as a download, as is this website.
(There are too many snake-oil charlatans.)
