| DESCRIPTION | ||
| It was designed to simulate multiple clients. It uses asynch IO API in | ||
| libevent to handle multiple clients. A client connects to the relay, | ||
| negotiates the session, and sends multiple (configured number) messages to the server (relay), | ||
| expecting the same number of replies. The length of the messages is configurable. | ||
| The message is an arbitrary octet stream. | ||
