Do you ever zip up your source code, and email to someone, only to have it bounce back because your zip file was too large? Then you realize it has the executables and debug files included in it?

Well, someone else had this same problem. So they created Clean Sources, which allows you to right click on a folder and tell it to clean your source directory. What does that mean? It removes the binaries, debug files, etc. that aren't needed when you send someone else your source code. It's a nice little tool.
