## Commands

| Script                 | Description |
| -----------------------|-------------|
| `npm run build`        | Builds project to `lib/`. |
| `npm run seed`         | Takes data from the libraries [countryjs](https://www.npmjs.com/package/countryjs) and [country-list](https://www.npmjs.com/package/country-list) and updates `data/iso-alpha-*.json` and `data/country/*.json` files. |
| `npm run generate`     | Takes seeded data, makes variants of names, checks for clashes (there's no mechanism to handle clashes as it's not come up) and dumps the data to `data/names.json`. |
| `npm test`     | Runs tests. |
