I will be ripping a site from a content management system that allows for you
to have multiple designs applied to the content using query string parameters

So for the rich page you would go to 

www.example.com/home

and for the text only design 

www.example.com/home?design=text

What i want to do is to collect all the pages for the text design, and rewrite
the links in the page to be

www.example.com/text/home

I can gather all the pages with no real issue, but i am struggling with the
url transform as i want to modify the url and add an additional dir in to the
path rather than make all the urls relative.

Is this something that i will be able to do simply with httrack?
