+You can customize the commandline options (if used) for the different zip formats.
+If you want to force local for the `tgz` output add this line:
+
+.. code-block:: scala
+
+  universalArchiveOptions in (Universal, packageZipTarball) := Seq("--force-local", "-pcvf")
+
+This will set the cli options for the `packageZipTarball` task in the `Universal` plugin to the following sequence.
+Currently these task can be customized

+    `universalArchiveOptions in (Universal, packageZipTarball)`
