We all know that code duplication is the root of all evil. (Well, a sort of.) Still we rush and copy code all the time. Now that you have those important features implemented, wouldn't it be nice to go back in time, find copied fragments and refactor them?
This is exactly what SimilarCode was made for. It looks for pieces of copied (or just very similar) code throughout your projects and presents the results for your viewing (and refactoring) pleasure.
SimilarCode will even find the copied code after you rename some variables, insert or alter a few statements, or do other small changes.
