    <para>
      <application>libevent</application> is an asynchronous event notification
      software library. The <application>libevent</application> API provides a
      mechanism to execute a callback function when a specific event occurs on
      a file descriptor or after a timeout has been reached. Furthermore,
      <application>libevent</application> also supports callbacks due to
      signals or regular timeouts.
