I am very thankful to my parents, especially my mother, whose prayers are with me all the time. I am grateful to the many friends and well-wishers who have supported and encouraged me both through the duration of this project and throughout my life as a whole.

In the preparation of the book, I would like to thank Rukhsana Khambatta for turning a book idea (that began in my mind) into reality. In addition, I am indebted to the entire team at Packt Publishing, including Susmita Panda, Sai Gamare, Arshad, and others. Last but not least, my thanks to those who reviewed this book and provided me with feedback, especially Steffen Macke for his invaluable suggestions.

I apologize to anyone whom I have failed to mention. There are many people who have helped me in this process and who have encouraged the creation of this book. To all of you, I extend my most heartfelt thanks.
