# face-unlock-bin - the Arch build of face-unlock
# (https://git.felo.gg/LoonixTools/face-unlock), made by upstream's release
# workflow: the same program as the face-unlock package, with OpenCV linked in
# statically, so an OpenCV update on Arch does not break it.
#
# Not every release has the tarball (2.0.0 and older do not), so the newest
# release that has it is tracked, not /releases/latest. Gitea keeps no digest
# for release assets, so the checksum comes from downloading the tarball.
