Software reuse should be understood as a technical procedure to be followed in order to reduce the effort of development and maintenance of a program. In other words, software reuse is the reapplication, on a definitive system, for the information, as well as the artifacts, obtained from other similar systems. This work describes a reutilization tool, based on Prieto-Diaz model, and its application is examined, as well as possibilities of its extensibility in future works are discussed.
