--list
--create=NEWREF
--delete
--alias, -A
--collections, -c
When creating refs, the refspec value passed to the --create option is treated as COLLECTION-ID:REF-NAME and a mirrored ref is created. (This is an abuse of the refspec syntax.)
When deleting refs, all refs whose collection ID equals PREFIX are deleted.
