-/**
- * A very basic <code>SCPClient</code> that can be used to copy files from/to
- * the SSH-2 server. On the server side, the "scp" program must be in the PATH.
- * <p>
- * This scp client is thread safe - you can download (and upload) different sets
- * of files concurrently without any troubles. The <code>SCPClient</code> is
- * actually mapping every request to a distinct {@link Session}.
