        return "Unknown action"

}

server.start()

dispatchMain()

import Foundation
import Procbridge

let port:UInt16 = 8000

let client = PBClient(host: "127.0.0.1", port: port)

print(try! client.request(method: "echo", payload: 123))
print(try! client.request(method: "echo", payload: ["a","b","c"]))
