	• The actual tool and approach has limited power • Can help translate one of Parnas’ KWIC decompositions to the other • Too limited to be useful in practice – PDGs are limiting • Big and expensive to manipulate • Difficult to handle in the face of multiple files, etc. • May encourage systematic restructuring in some cases • Some related work specifically in OO by Opdyke and Johnson • Question: How do you find appropriate restructuring?
