varde/.gitea/workflows/release.yml

# Release pipeline: a `vX.Y.Z` tag (pushed by `cargo release`, see
# release.toml) builds distribution tarballs and attaches them to a
# Gitea release.
#
# Each tarball contains the two binaries (stripped, release profile),
# the systemd units, the example config, rendered man pages, and the
# license/readme — everything a distro package or a hand install needs.
