Abstract

Cloning is considered a harmful practice for software maintenance because it requires consistent changes of the entities that share a cloned fragment. However this claim has not been refuted or confirmed empirically. Therefore, we have developed a prototype tool, CloneTracker, in order to study the rate of change of applications containing clones. This paper describes CloneTracker and illustrates its preliminary application on a case study.
