working effectively with legacy code ebook

The tests were hard to write, and the team didn't run them very often because they took so long to run. Special thanks to all of the people who reviewed the drafts. Their love and support made this book and all of the learning that preceded it possible. Special thanks also to Gary and Joan Feathers, April Roberts, Dr. Raimund Ege, David Lopez de Quintana, Carlos Perez, Carlos M. Rodriguez, and the late Dr. John C. Comfort for help and encouragement over the years.I also have to thank to Brian Button for the example in Chapter XX, I'm Changing the Same Code All Over the Place.

He said, "They're writing legacy code, man." Special thanks also to Paul Petralia, Michelle Vincenti, Lori Lyons, Krista Hansing, and the rest of the team at Prentice-Hall. I apologize in advance to any of you I may have left out. That definition of legacy code has nothing to do with who wrote it.
