I am trying to find a tool that will help me to quickly identify the changes on
a website from one day to the next.

Ideally, I could create a "deltas report" from the 2 snapshots that would show
what the changes are.  I need to do a word count on the changes.
 
Does HTTrack support this? 
If not, do you know of a tool that does? 
Thanks for your help.
