We'd like to thank all the people who helped make this book possible: Ross Mason, founder of the Mule project and MuleSource for somehow making the time for a thorough technical review; Susan Forshaw, who is helping drive Ricston forward; Wendy Devolder, founder of Skills Matter; and Lisa Hamilton and everyone with Ricston, Apress, and MuleSource that contributed in one way or the other. Last but not least, we hope this book helps readers start to tap the power of Mule!
