+This is a copy of sg_map_areg_bdgs_migration_bundle.py with issue-specific
+adjustments.
+
+This script is solely intended for transforming the bundle exported as part of
+TI-1703 (transforms the bundle in-place).
+
+It deletes all exported repository folders from the bundle, because
+in this specific case every single source repository folder is mapped to
+an (existing) target repository folder - therefore no complicated logic is
+needed to determine which repository folders to keep.
+
+Dossiers are mapped to their target position according to the Excel sheet
