Software Re-Documentation Process and Tool

Researchers and professionals know the importance of the documentation for the efficient maintenance of legacy software. Unfortunately , many legacy systems lack this important artifact. Maintenance then becomes a difficult process where software engineers must study and understand the system over and over again. A possible solution out of this situation is to re-document the legacy system. In this article we will present a software re-documentation process, its main features, and constituting activities. We will also present a tool we are developing to automate this process as much as possible. This tools runs in Java and is currently designed for Visual Basic legacy systems.
