About Code in Motion

In their chapter, Code in Motion (PDF, ©2007 O'Reilly), Laura Wingerd, Perforce vice president of product technology, and Christopher Seiwald, Perforce president and CTO, discuss "code in motion"—source code that survives and thrives in an evolving, long-lived software product. The real-world case they cite is that of "DiffMerge," a component of the Perforce SCM System.

For Code in Motion readers, the DiffMerge source code is reproduced here.
