Use -B for --backing-format, keep -F for backwards compatibility. Options added: --format, --cache - for the image in question --backing, --backing-format, --backing-cache, --backing-unsafe - for the new backing file (was eg CACHE vs SRC_CACHE, which is unclear). Probably should rename local variables.
