# As of 07 December 2022, per https://pkgs.org/download/transifex-cli, only
# Void Linux and KaOS package the new Go-based Transifex CLI officially, so our
# safest bet is to pull the binaries from GitHub Releases directly for now.
#
# These binaries do not dynamically link to anything, and thus should work on
# glibc and musl (Alpine, Void, etc.) systems equally well.
