# librepods-bin - prebuilt package of https://github.com/librepods-org/librepods
# (AirPods integration for Linux, Qt6/C++ client in the linux/ subdirectory).
#
# Upstream releases carry only Android APKs, so build_artifact() builds the
# Linux client from the release tarball. Upstream tags look like v1.0.0-rc1;
# pkgver strips the hyphen (1.0.0rc1, sorts before 1.0.0 in vercmp) and
# build_artifact re-inserts it for the tag URL.
