 In some more involved cases the output files need to be edited. For example `ServiceStack` has Nuget dependencies, which
 are included in the `Microsoft.NETCore.App` framework stub. These dependencies generate empty packages, which can be
 removed. The `ProjectReference` entries referencing these removed empty packages also need to be deleted from the

+python3 make_stubs_all.py
+python3 make_stubs_all.py /Users/tmp/working-dir

+The script contains a hardcoded list of `packages`. If a new package is needed for test purposes, it should be added to the `packages` list in the script.
