Hmmm - I was pretty skeptical that this would be helpful when I read 
this.  I went to the cited page and checked out.  It wasn't all that 
clear what this thing does and how to use it.  I probably could figure 
it out if I had time to do so though.  But I can't believe that using it 
would be simpler, faster or more effective than the procedure I just 
outlined above.
