have remained just thatan idea—but for two people: my father, Dr Appa Rao, who encouraged me to go ahead with the plan and explained why it was a good idea, and my wife, Valerie, who not only supported the idea, but also backed it up with a lot of sacrifice over the last year I'm grateful to both for helping make my idea a reality This book has benefited from the suggestions of several good technical reviewers Sheldon Barry reviewed the first half of the book and Martin Reid reviewed some of the early chapters Thanks to both of you, Sheldon and Martin The reviewer who spent the most
