Not quite it, but autoconf-archive has some tooling around it: * https://github.com/autoconf-archive/autoconf-archive/blob/81e26138e807b9ecb3c19b953e8776ff9e415fdf/macro.py#L112 * https://github.com/autoconf-archive/autoconf-archive/blob/81e26138e807b9ecb3c19b953e8776ff9e415fdf/set-serial.sh#L20 Maintainer mode is integrated with this so it updates serial numbers automatically.
