auspinner is a stateless CLI tool to easily pin CAR files to IPFS pinning services. It's essentially a client for the IPFS Pinning Service API that speaks HTTP and Bitswap.
Serve them over Bitswap by connecting to the delegates returned from the pinning service
Alternatively, if no delegates are returned, the --use-origins flag uses libp2p NAT port mapping to get a public address which is passed in the origins to the pinning service
