This book would not have been written without the help and support of some great people: first of all, the Packt team and especially Usha Iyer, Leena Purkait, and Chaitanya Apte. Your guidance and patience during our first writing adventure was amazing.
We would also like to thank Dries Buytaert, the creator of Drupal and Ryan Szrama, the creator of Ubercart. Your personal projects became so important, that they affect the lives of thousands of people daily.
And of course, the Drupal and Ubercart communities for providing ideas, solving problems, and contributing fantastic modules.
