# TODO: once builder has IPv4, consider replacing most usage with lua-aports' buildrepo (https://gitlab.alpinelinux.org/alpine/lua-aports/-/blob/master/buildrepo.1.scd)
#       Example of usage:
#       $ buildrepo -a "$PWD/src" -d "$PWD/target" -R memdmp util utau
#         -> This also allows cross-arch building assuming https://wiki.alpinelinux.org/wiki/How_to_make_a_cross_architecture_chroot is setup via e.g. CBUILD=aarch64

# note: we assume `abuild-keygen -a -i` has alr been run
