+To have an idea about how many errata and also how many packages per errata on avarage were created the following tool can be used:
+
+    bundle exec analyzer.rb <errata-json>
+
+It is also possible now to check if the latest security-notices that can be found on the RSS-feeds are already part of the errata-file.
+The `check_latest_errata.rb` command returns a nagios-compliant output and return-code.
