+## WebSocket test tool
+`ws-test` reads the same configuration as `job-search` for its defaults:
+```bash
+go run ./cmd/ws-test dial --ping    # ping the HTTP server's /ws endpoint
+go run ./cmd/ws-test dial           # send each line of stdin, print replies
+go run ./cmd/ws-test serve          # plain TCP server for websocket hub clients
+```
+
+`dial` also takes `--message`, `--listen`, `--origin` (to test the Origin
+check), `--url` and `--timeout`; see `ws-test dial --help`.
