I've packaged and been using v1.2, please see https://salsa.debian.org/bap/lieer.git
which has a bunch of packaging updates, including a transition to the new name of lieer, with an appropriate transition package of course. I'd be happy to have the maintainer take whatever is deemed useful, or to upload it, NMU, co-maintain --- whatever the maintainer desires. Julian? Cheers, --Barak.
