`loop` binary, tells if you want to use deletion loops (`true`) or not (`false`) (if you use [an external script](https://framagit.org/framasoft/pad_delete_after_delay) for example). Default is true.
`loopDelay` delay in seconds between deletion loops. Deletion loop will check all pads to see if they have to be deleted. You can't put `60*60` for a hour, you have to put `3600`. Default is one hour.
`deleteAtStart` binary, tells if you want to start a deletion loop at Etherpad startup. Default is true.
