Introduction to the Special Issue of the 13th European Conference on Software Maintenance and Reengineering (CSMR 2009)

As the premier European forum for discussing theory and practice of maintenance, reengineering, and evolution of software systems, CSMR promotes discussion and interaction among researchers and practitioners regarding the development of maintainable systems as well as the evolution, migration, and reengineering of existing systems. The 2009 edition of CSMR focused on the theme 'Architecture-Centric Maintenance of Large-Scale Software Systems'. Many software developers and users are facing the maintenance and reengineering challenge today. They cannot escape from maintaining software systems and at the same time, they have to adapt their systems to evolving needs. At CSMR 2009, we observed a high interest in this topic from academia and industry by achieving the all-time CSMR-high on attendance.
