• coprolite-api contains Сoprolite loader api
• coprolite-loader contains platform-independent implementation of Сoprolite loader (if desired, it can be used at least as the client mod loader)
• coprolite-launcher contains launcher for Сoprolite loader, usually for PaperMC and its forks

Special thanks to FabricMC, a considerable part of the code is taken from fabric-loader
