21 * @file dht/gnunet-dht-driver.c
22 * @brief Driver for setting up a group of gnunet peers and
23 * then issuing GETS and PUTS on the DHT. Coarse results
24 * are reported, fine grained results (if requested) are
25 * logged to a (mysql) database, or to file.
27 * FIXME: Do churn, enable malicious peers!
