To start with, I'd grep the entire file for /\buse\s+([\w:]+)\b/ to find all the modules being used (at least via 'use' in any case).

Then for each module, search for /(?<!use\s+)$module\b/ to find all the OTHER uses of it in the file.

If the name of the module never appears anywhere else in the file, then it's almost certainly not used. :) Adam K
