# The Go binding links rgbconsignment/lib/<GOOS>_<GOARCH>/librgb_consignment.a,
# and those archives are committed so that `go get` works without a Rust
# toolchain. `libs` rebuilds all four whenever the Rust side changes and
# `commit-libs` pushes them back to the branch; `test` runs against whatever
# archive is committed.
