From the ACM record: "Software architecture reconstruction techniques may be used to understand and maintain software systems, especially in these cases where architectural documentation is outdated or missing. This paper presents the architecture reconstruction functionality of HUSACCT and describes how this functionality may be used and extended with algorithms in support of reconstruction research focusing on modular architectures. The tool provides a graphical user interface to select an algorithm, edit its parameters and to execute or reverse the algorithm. To study the results, browsers and diagrams are available. Furthermore, a user interface is provided to enhance the determination of the effectiveness of algorithms by means of the MoJoFM metric."
