Prints the NDB Cluster version number of the executable\&. The version number is relevant because not all versions can be used together, and the NDB Cluster startup process verifies that the versions of the binaries being used can co\-exist in the same cluster\&. This is also important when performing an online (rolling) software upgrade or downgrade of NDB Cluster\&.
