I ve worked on several projects writing and implementing specifications (particularly CLN): I ve found the specs I write are much better when I quote them in the implementation, so I can see what implementers need to know. Also, when specs change in development, it s almost trivial to find where to update the code.This project is a formalization of my various hacky scripts which ensure the requirements are accurately quoted, and give coverage if any are missing. Not a major Opus, but I hope someone else finds it useful!
