I would like to thank Packt Publishing for giving me the opportunity
to write my first book. A big thank you goes to my wife for her
encouragement and support throughout the time I was writing
this book. She takes excellent care of me and my kids. Thanks also
to Chris Alfonso for referring Packt's inquiry to me and for his
hospitality during the month my family ransacked his house. I'd
also like to thank my friends and colleagues, Clay Shelor, Alvero
Lopez Ortega, and Will Foster. These gentlemen provided feedback
and reviews invaluable to my content being properly written and
coherent for your consumption. Finally, I'd like to thank the Lord for
the life and breath given to His creation for the purpose of His glory.
