I'd like to thank my wife, Sara, for her caring support and understanding as I worked on the book at weekends and evenings, and to my parents, parents-in-law, sister, and grandmother for all their support, guidance, tutelage, and encouragement over the years. I'd also like to thank Packt, especially the editors, Tushar Gupta, and Karan Thakkar, and everyone else in the team, whose persistence and attention to detail has been exemplary.
