About Eiffel

This repository forms part of the Eiffel Community. Eiffel is a protocol for technology agnostic machine-to-machine communication in continuous integration and delivery pipelines, aimed at securing scalability, flexibility and traceability. Eiffel is based on the concept of decentralized real time messaging, both to drive the continuous integration and delivery system and to document it.
