Hmm, this looks like a fork that extracted KJ from the Cap'n Proto repository 4 years ago and hasn't been updated. KJ has been continuously developed (as part of Cap'n Proto) over that time, so this is outdated.<p>The Cap'n Proto repo itself allows you to build and link against KJ independently of capnp. So if you only want KJ, there isn't really any downside in using the version as it exists in the Cap'n Proto repo.<p>Anyway I'm glad people like KJ!
