| Emulating a network card is supported. It can be used by passing the | |
| `network_relay_url` option to `V86Starter`. The url must point to a running | |
| WebSockets Proxy. The source code for WebSockets Proxy can be found at | |
| https://github.com/benjamincburns/websockproxy. | |
| The network card could also be controlled programatically, but this is | |
| currently not exposed. |
