+# Based on upstream's own wheel build at this tag (the python-manylinux job of
+# .github/workflows/packaging.yml, ci/scripts/python_util.sh's build_drivers and
+# ci/scripts/python_wheel_unix_{build,relocate}.sh):
+#   https://github.com/apache/arrow-adbc/blob/apache-arrow-adbc-24/.github/workflows/packaging.yml
+# Unlike adbc-driver-postgresql/adbc-driver-sqlite, this driver's shared library
+# (c/driver/flightsql -> go/adbc/pkg/flightsql, via CMake's add_go_lib) is a cgo
+# `go build -buildmode=c-shared`, not a plain C/C++ CMake target, so the manylinux
+# image needs a Go toolchain added (the image ships none). The pinned version comes
+# from upstream's own .env (the same read native-unix.yml's "Get required Go
+# version" step does) and go.dev ships a linux-riscv64 tarball for it. setup.py
+# still copies the resulting libadbc_driver_flightsql.so into the package and the
+# relocate script's retag step is reproduced inline since it isn't vendored as a
+# package file we can invoke directly. See build-adbc-driver-manager.yml for why
+# the checkout uses the Go module tag. Testing mirrors native-unix.yml's own
+# "Test Python Driver Flight SQL" step: build go/adbc's own
+# driver/flightsql/cmd/testserver and run the wheel's tests against it locally,
+# no external Flight SQL service (Dremio/GizmoSQL) needed.
