+	This script tests whether uploaded parts can be skipped in a

+	On Minio: yes, parts can be skipped

+	On S3: not tested

+
+	Conclusions:
+
+	- Skipping a part in a CompleteMultipartUpoad call is OK
+	- The part is simply not included in the stored object
+	- Sequential part renumbering counts only non-skipped parts
