Where `geth-spec.json` is your Geth spec file.

The resulting spec can be then used in Parity with `parity --chain parity-spec.json`.
The resulting converted file will be printed to the console, then you can save it as json file (for example `parity-spec.json`).

Finally it can be used in Parity with `parity --chain parity-spec.json`.
