Such customizations usually define variants, with a common code base and well documented variabil- which features are offered by the components, and may depend ity [1, 6, 19]. Modern software systems are often built as complex on backend components being configured in a specific way. As assemblages of customizable components that out-grow the expres- such system become very large, with a huge number of possible siveness of SPLs.
