This a product of my last two or three weekends. It actually began as a duplicate file finder and has grown upto a source code search tool powered by Ctags the famaous code indexing utility.
The duplicate finder works based on file hashes using the Tiger Hash algorithm (BouncyCastle's impl).
The Code search is simply a UI to search Ctags tag files in each of your configured code repositories.
