Lyn Dupré was the developmental editor. She has a special gift for rooting out problems and suggesting improvements. The errors in this book were introduced—by authors who never stop writing—after Ms. Dupré finished her work.

If you write technical material, you should read Ms. Dupré's book Bugs in Writing: A Guide to Debugging Your Prose (revised edition), (Addison-Wesley, 1998).
