In this paper, we propose an automated method for detecting and tracking homologous code in genealogy of evolving software using fine-grained tree differencing on source code. Such a tool would help software developers/maintainers to better understand the source code and to detect/prevent inconsistent modifications that may lead to latent errors.

This paper reports on a tool for fine-grained analysis of structural changes made between revisions of programs. The tool, called Diff/TS, calculates, visualizes and classifies edit operations including moves that will change one revision into another by means of detailed tree structural analysis on source code.
