Batch replace copyright comment in XCode

I've been working on an iOS project for some time now, creating hundreds of source files, and now that's it's good and done, I realize something sad : I edit the copyright file template before getting to work, and all of my files have this lame format : ``` // // MyClass.h // // Created by Redwarp on 3/25/13. // Copyright (c) 2013 Redwarp. All rights reserved. // ``` And that's not cool ! I would like to replace it with something more like that : ``` /* This software is licensed under the Apache 2 license, quoted below.

I could probably write a script, that searches all my files and replace the first "//" lines with a better comment, but I'm sure there is a tool out there that does that perfectly. Except : I can't find that tool anywhere. Would anyone know of such a tool ? (Or might it be that I'm a fool ?)
