There is one other script, `get-traditional.sh`, which simply gets the value of a row in the traditional way, with no deltas. There are two other scripts, `get-traditional.sh`, which simply gets the value of a row in the traditional way, with no deltas, and `del-traditional.sh` will delete an asset in the traditional way.
