Many thanks are due to Tor Andersson for creating MuPDF, to everyone who has contributed to it over the years, and to all my colleagues at Artifex Software for providing an environment in which it could grow, and nursing it through to maturity. Particular thanks are due to Sebastian Rasmussen for patiently proof-reading the book through its many revisions, and suggesting numerous improvements.
Finally, many thanks are due to Helen Rogers, for putting up with me.
