The Epeios Research Project has led to the development of a set of generalist, and some less generalist, C++ libraries, which are published under free license (GNU AGPL). The backend/frontend protocol, the registry-based configuration system, the XML preprocessor and XDHTML are some of the technologies produced by the Epeios Research Project.
The Atlas toolkit also exists and is continuously improved thanks to the Epeios research project.
If you want to support all these projects, and also help me to provide a freely accessible server for all those who need the Atlas toolkit, please make some donation by following this link:
Many thanks to all donors!
