Clone Detection and Clone Manipulation The DRY principle says that a particular code fragment should not be repeated more than once in a program. But it happens. And when it does, it is good to be able to find the multiple code "clones." A variety of tools have been designed for this, and some of them even allow joint editing of the clones. Survey the techniques for dealing with the problem, and compare the effectiveness with refactoring (e.g., Extract Method).
