+Test modification of configuration
+==================================
+
+Testing that later runs adapt to configuration changes even if the repository is
+unchanged.
+
+adding more formats
+-------------------
+
+bundle for added formats should be generated
+
+change configuration

+------------------
+
+Changing the ratio to something that would have triggered a bundle during the last push.
