23// This program conducts a Bianchi analysis of a wifi network.
24// Bianchi analysis involves saturating the network and observing how
25// the maximum achievable throughput is governed by the DCF or ECDA
26// channel access mechanisms. This program offers many configurable
27// options, traces, and a validation option; the main output is a Gnuplot
28// plot file plotting throughput vs. number of nodes.
