Thanks so, so much is explained, but oh so little documentation exists

In fact, as per myth's coding standatds, a 10 line explation would be so useful!
if you run the grabber within the frontend nothing is logged and mythmetadata is not \
run. But your wise words will help troubleshoot. (run the frontend in a terminal to \
view the detail) James
