A tool suite for evolving legacy software

Evolving an existing software system is fundamentally different from developing one from scratch. Consequently, tools to support evolution must go beyond traditional development tools. The paper describes the Esprit de Corps Suite (EDCS) of software evolution tools. EDCS supports the mission oriented architectural legacy evolution (MORALE) software reengineering process. The paper briefly describes MORALE before presenting the individual tools and how they interoperate to support legacy system evolution.
