 This will produce a labsjdk installation under `build/labsjdks/release` along with 2 archives in the same
 directory; one for the JDK itself and a separate one for the debug symbols.
 
+NOTE: if you want to pass options for `configure` in OpenJDK, you can pass the file location which lists them in each line to `--configure-options` on `build_labsjdk.py`.

 You can verify the labsjdk build with:
 ```
