  # If you need to set some config variable only in a local branch, then add an overwrite here

  # One example is DISABLE_HRTF - this will be set on a branch which is about to be merged and will be removed in a subsequent second MR

  # this is more easily done directly here in the child repo

  # these lines are suposed to stay commented out to serve as an example

  # # set this to true to skip the external HRTF testcases in pytest calls
