PRET-Extractor (PRoduct Evolution Tree Extractor) is a tool that extracts the Product Evolution Tree, approximation of the evolution history of software products, from source code of products.
A large number of software products may be derived from an original single product. Analyzing such a large number of software products is a difficult task for developers.
Since analyzing a large number of software products at once is a difficult task for developers, it is efficient that conduct the analysis on typical products first and then expand the scale as necessary. If an evolution history of software products is available, developers could recognize the relationships among the products and choose representatives for their analysis. However, such a history of products is often not available for developers. In the worst cases, developers only have access to source code of each product.
PRET-Extractor takes source code as input and visualizes a Product Evolution Tree. Similar products are connected on the tree so that users are able to understand the relationship among products.
