Our investigations of these systems have involved the creation of software architecture models, software architecture repair, the creation of a reference architecture for web servers, the study of evolution and growth of open source systems, and the modelling of architectural properties of systems that are apparent only at build time. %B 1st Workshop on Open Source Software Engineering at ICSE 2001 %> https://flosshub.org/sites/flosshub.org/files/hassangodfreyholt.pdf
