Our first example of generated tools are renovation factories as needed for the analysis and remediation of legacy systems. Such factories are generated tools with the architecture as already shown in Figure 2. All the ingredients of such factories are generated from language specifications. Although our approach is completely generic, we will illustrate it here by way of examples for the COBOL language. We give now first a quick overview of the main ingredients of software renovation factories, then we discuss applications, and finally we give some measurements.
