### Protocol Compliance
The Gorilla WebSocket package passes the server tests in the [Autobahn Test
Suite](http://autobahn.ws/testsuite) using the application in the [examples/autobahn
Suite](https://github.com/crossbario/autobahn-testsuite) using the application in the [examples/autobahn
subdirectory](https://github.com/gorilla/websocket/tree/master/examples/autobahn).
