It is a modified version of tests/simple/main.cpp from the GitHub codebase:

int main() {
try {
  const auto localhost = ClientOptions().SetHost("hostname").SetPort(8080).SetUser("user").SetPassword("password");
  Client client(localhost);
} catch (const ProtocolError & e) {
  cout << e.what();
} catch (const std:: exception& e) {
  cout << e.what();
}
return 0;
}
