rafaelff [1] filed a deletion request for classix [2]: Source tarball URL is broken. Even though the upstream URL redirects to a GitHub repository (https://github.com/leofontenelle/classix), the development stopped 9 years ago. I tried adjusting the PKGBUILD for the unreleased upstream rewrite in progress, but it is too buggy.
