+# Build environment for modding/hacked/ (vendored from
+# https://github.com/inkyblackness/hacked, see ../README.md). Fetches the Go
+# toolchain and this module's dependencies once, here, at image-build time, so
+# ../hacked-build-run-image.sh can compile fully offline afterward. Rebuild
+# with ../hacked-build-image.sh whenever a version below changes, or whenever
+# ../hacked/go.mod or go.sum changes (its dependencies are baked into the
+# image's module cache).
