We have an alternative solution that hooks into the package QA. It focuses on directories that are supposed to be empty. In addition to failing the build if there are files in such a directory, it also allows to specify for each directory why it should be empty. We have used this, e.g., to mark common directories that have been renamed to give an indication of where the files were supposed to have been installed. Do you want me to generalize this and send a patch for it? //Peter
