name: Release

# A tag like v0.1.1 builds budctl and budctl-gui for x86_64 and aarch64 Linux and publishes them,
# with install.sh and checksums, as a GitHub release. The builds run on Ubuntu 22.04, so they need
# glibc 2.35 or newer and nothing else at build time: Wayland and xkbcommon are loaded at runtime.
