Writing a book is not a solo or duo exercise. This result could not have been achieved without the contributions of a great team.

Steve Dark performed the technical review of this book. His insightful comments and suggestions have added an extra dimension of quality to the book. For that we thank him. We also wish to thank Ralf Becher and Stephen Redmond, who did the technical review on the previous edition of this book.

We also want to thank Packt's team: Aishwarya Pandere, content development editor, and Dinesh Pawar, technical editor. Their guidance kept us focused and on track.
