What rules does C Four enforce?

C Four enforces a process aimed at creating an inclusive and forward-moving environment for software development. Pieter Hintjens describes it as a system where contributors are welcomed, and their patches are merged if they follow basic rules regarding style and commit messages, regardless of personal opinions or the maintainer's beliefs. This approach prevents elitism and encourages problem-solving through continuous progress rather than dwelling on issues, thus significantly increasing contributions and reducing conflicts within the community 1.
