Use: "syncAndPublish",
Short: "Syncs all Ethereum data into IPFS, indexing the CIDs",
Long: `This command works alongside a modified geth node which streams
all block and state (diff) data over a websocket subscription. This process
then converts the eth data to IPLD objects and publishes them to IPFS. Additionally,
it maintains a local index of the IPLD objects' CIDs in Postgres.`,
