A wonderful tool to analyze a text to find out the most frequent words in it.
See here the result on a 12-pages document I wrote back in 2002 at Agilent Technologies for the introduction of a new product : the Modular Network Tester. This document was aimed at presenting the new platform to the sales channels. Look at the corresponding cloud, and you'll get the message ;-)
Thanks to Bruno Giussiani for the heads up.
