I found this on StackOverflow - you may want to contact this person at Clone Doctor.

I'm completing a CloneDR-based duplicated code finder tool (see www.se
+manticdesigns.com/Products/CloneDR) for Perl. I really like real exam
+ples. Can I have your 30 files? If it all works, I'll send you the re
+port and eventually the production tool. (Zip file?) – Ira Baxter Jun
