Ian: Congratulation to our accepted paper for CSM'89. Here are some initial thoughts on our paper on Tools for Preventive Software Maintenance: preventive maintenance means: attempts to anticipate, simplify, prevent future maintenance. Tools which anticipate, simplify: Law checker Parameterizer Growth plan generator Evolution tool some evolution steps can be done automatically Tools which prevent (automate): Parameterizer Task: We have to take a close look at the ECOOP review. Possible approach to paper: We deal with maintenance of object-oriented software only. We discuss the benefits of the Law to maintenance AND the benefits of the grammar-based approach in general. We have too much material for this paper. We have to find a good focus for our paper. What are your ideas? -- Karl
