This book would not be possible (nor very useful) if Subversion did not exist. For that, the authors would like to thank Brian Behlendorf and CollabNet for the vision to fund such a risky and ambitious new Open Source project; Jim Blandy for the original Subversion name and design—we love you, Jim; Karl Fogel for being such a good friend and a great community leader, in that order.
Thanks to O'Reilly and our editors, Linda Mui and Tatiana Diaz for their patience and support.
Finally, we thank the countless people who contributed to this book with informal reviews, suggestions, and fixes: While this is undoubtedly not a complete list, this book would be incomplete and incorrect without the help of: David Anderson, Jani Averbach, Ryan Barrett, Francois Beausoleil, Jennifer Bevan, Matt Blais, Zack Brown, Martin Buchholz, Brane Cibej, John R.

 Oh, and thanks, Karl, for being too overworked to write this book yourself.
