Yes, that was my thinking. Up to you on whether it's better or just overly
wordy.

Okay, so I guess this is fine. I chatted with Dean about this today and it
sounds like the workflows he was worried about do actually work (namely,
copying a tarball from DTS engine to SUT) but that there is an added
requirement that a flag be added (i.e. you can't just run main.py alone
anymore) and it's unclear to him (and me) why this might be the case. I can
try and take another look tonight, but I'm basically happy now that I know
the workflows Dean was concerned about are tested and work.
