Software (Re-)Engineering with PSF

Abstract: This paper investigates the usefulness of PSF in software engineering and reengineering. PSF is based on ACP (Algebra of Communicating Processes) and as some architectural description languages are based on process algebra, we investigate whether PSF can be used at the software architecture level, but we also use PSF at lower abstract levels. As a case study we reengineer the compiler from the Toolkit of PSF.
