All the data continuously generated in your IT infrastructure 
contains a definitive record of customers, application performance, 
security threats, fraudulent activity, and more. Splunk takes this 
data and makes sense of it. IT sense. And common sense.

Looks fine to me ; I'll assume that this is going upstream via the nuc900 maintainer since the module split up is old news at this point in time.

Thanks,
Paul.
