	Short: "A simple tool to extract the private key from an eth wallet",
	Long: `
This function can take a geth style wallet file and extract the private key as hex. It can also do the opposite

This command would take the private key and import it into a local keystore with no password

$ polycli parseethwallet --hexkey 42b6e34dc21598a807dc19d7784c71b2a7a01f6480dc6f58258f78e539f1a1fa

If we wanted to go the opposite direction, we could run a command like this:

polycli parseethwallet --file /tmp/keystore/UTC--2023-05-09T22-48-57.582848385Z--85da99c8a7c2c95964c8efd687e95e632fc533d6  | jq '.'
