GIven that the users will have to update the CMD file to avoid "collision" with other applications, I'd prefer that we prefix the env vars that go into the csdef file something like: NEWRELIC_LICENSE_KEY - then change the CMD file to look for that.  

I just want to make sure we do no harm, especially if another package, vendor or user ends up using the general term: "LICENSE_KEY."  More like namespacing the keys. Let em know your thoughts.
