+# This function allows developers to specify the impacted scenario by adding
+# the info about installer and scenario into the commit message or using
+# the topic branch names. This results in either skipping the real verification
+# totally or skipping the determining the installer and scenario programmatically.
+# It is important to note that this feature is only available to generic scenarios
+# and only single installer/scenario pair is allowed.
+# The input in commit message should be placed at the end of the commit message body,
+# before the signed-off and change-id lines.

+#
+# deploy-scenario:k8-nosdn-nofeature
+# installer-type:kubespray
