* Create a topology given a peer group (set of running peers)
- * and a connection processor.
+ * and a connection processor. Creates a small world topology
+ * according to the rewired ring construction. The basic
+ * behavior is that a ring topology is created, but with some
+ * probability instead of connecting a peer to the next
+ * neighbor in the ring a connection will be created to a peer
+ * selected uniformly at random. We use the TESTING
+ * PERCENTAGE option to specify what number of
+ * connections each peer should have. Default is 2,
+ * which makes the ring, any given number is multiplied by
+ * the log of the network size; i.e. a PERCENTAGE of 2 makes
+ * each peer have on average 2logn connections. The additional
+ * connections are made at increasing distance around the ring
+ * from the original peer, or to random peers based on the re-
+ * wiring probability. The TESTING
+ * PROBABILITY option is used as the probability that a given
+ * connection is rewired.
*
* @param pg the peergroup to create the topology on
* @param proc the connection processor to call to actually set
* up connections between two peers
