How to use the terminal-kit.terminal.processExit function in terminal-kit

term(`\nGenerating ECDSA keypair...`)
    const key: Key = ks.genKeyPair(conf.callsign)
    await timeout(2000) // delay for dramatic effect, lol
    term(`\nPublic Key: ^c${key.public}^\n`)

    // signatures are created using a private key, but we don't want to include
    // the private key in the config file, so instead we use the public key
    // as the identifier, and then actually sign with the private key.
    conf.signingKey = key.public
