Hey again!

i was wondering if someone could help me out.
What i want to do, is use a breadcrumb style navigation script, what i want it to do it look at the url, and take certain things from it,
so if the link is this: index.php?page=tutorials&page=list&cat=photoshop
it would make "Site Name > Tutorials > Photoshop"

Thanks to anyone that can help! :D
