In Modulafor Macintosh consisting of4 2.1 andB 2.1 2. In Pascalfor Macintosh consisting of4 1.3.1.1 andB 2.1 3. In Modulafor Sun, consisting of4 2.1 andB 1.2.1.1 This information cannot be inferred from the version trees in Fig. 2.1-2. After somerevisions of the different variants have been developed it turns out that component A must be implemented differentlon both machines, as well as component B has to be developed in two variants according to the programming languagestoo (instant 2). The resulting version trees are presented in Fig. 2.1-3. Fig. 2.1-3 The project's version tree at instant 2 This small example shows thelte chronological ...
