Abstract
The Base Variability Resolution (BVR) is a modern language to build software product lines (SPL). The language incorporates advanced concepts for feature modeling, reuse and realization of components in SPL. The BVR bundle implements and supports the language. The tool covers design, implementation and quality assurance to close the development cycle. The bundle enables feature modeling, resolution, realization and derivation of products, their testing and analysis. We integrate the SPLCA additions to provide the state of the art algorithms for analysis. The project is open-source and available for practitioners. The tool consists of Eclipse plug-ins which work seamlessly together as well as separate stand-alone components. We describe how the tool collaboration contributes to variability modeling. In addition, we present how the bundle applies well-known design patterns, principals to achieve synergy between components.
