# faugus-launcher-bin - Faugus Launcher
# (https://github.com/Faugus/faugus-launcher), a GTK4 front-end for running
# Windows games through UMU-Launcher.
#
# Upstream publishes an architecture-independent .deb per release, which the
# PKGBUILD repackages. The Debian revision in the asset name is not derived
# from the version, so refresh_checksums() resolves the asset via the GitHub
# API and syncs the _asset variable in the PKGBUILD along with the checksum.
#
# Upstream tags carry no "v" prefix.
