Find all the modules 'use'd in a directory

[Matisse Enzer]

I want to utility program that I can point at a list of files and/r  
directories and get back a list of all the unique modules/pragmas that  
are imported via 'use'

Before i write my own, using PPI, does this exist already in the CPAN?
thanx!
