+# If you run `go build` a header "libgojsonnet.h" will be autogenerated in
+# this directory. Then it can be picked up by Gazelle and added to `srcs` here.
+# When building with Bazel the file gets created elsewhere in Bazel's
+# sandbox tree, so when using Bazel exclusively it won't cause any trouble.
+# However, sooner or later someone is going to run Gazelle after using `go build`
+# and then the file may slip in, so it's better to just exclude it explicitly,
+# with the directive below:
+# gazelle:exclude ./libgojsonnet.h
