@jasonbosco It's nice to know that this is being done. I already started testing this myself, without documentation (heh) and ran into an authorization problem. Now `api_key` is not used...

The real reason for this is the non-standard structure of the tar file. To fix the error we need to change the `normalizeTar` function. But my PR have no answer...
