Software maintenance is the main driver of total costs in the lifecycle of long-living software systems. Code clones, that is, the replication of code fragments across the system, decrease maintainability: It increases the code size and hinders manual code change, inspection, and analysis. Intensive research has been spent in the last two decades to determine the nature of clones, specifically why and where they occur as well as whether they impair the maintenance of software systems. While
