Twill example issue

[Krishnachaitanya C Potluri]

Hello All,

We could really use Twill if there is some good working examples out there. I 
am trying to run hello world and I am seeing this issue. Can someone tell me 
where is twill looking for the jar and how can I tell it look in a certain 
folder?
