Open-source automated grading of programming assignments
Web-CAT is a plug-in based web application for automatically grading programming assignments in many programming languages. This project also provides Eclipse plugins for electronic submission and feedback services directly from the Eclipse IDE. We now use github for source code control (https://github.com/web-cat), although all file releases are still provided here through SourceForge. The CVS repository here is for archival purposes only.
