Module: vflow
Version: 0.1b

Description
Vflow is a ruby module similar to perl's Cflow and python's pyflowtool. 
It provides an interface to the flow-tools library to process flow 
files captured by flow-tools flow-capture program.

For example, you can print the source and destination of each flow 
thusly,

require 'Vflow'
vf = Vflow.new()
vf.open('aflowfile')
vf.each() { |r|
         # print time srcaddr:dstport -> dstaddr:dstport
         print "#{Time.at(r.unix_secs)} "
         print "#{IPSocket.getaddress(r.srcaddr)}:#{r.srcport} -> "
         puts "#{IPSocket.getaddress(r.dstaddr)}:#{r.dstport}"
}
vf.close()
