Whenever I create a new .cpp/.h file in Xcode a comment is added to the top of the file. For example:

This blog post has some good steps for modifying file templates in Xcode 4.3:

The /Developer folder no longer exists, so you copy the templates from within the Xcode.app bundle located in /Applications:
/Applications/Xcode.app/Contents/Developer/Library/Xcode/Templates/File\ Templates/
And place your modified copy here, as before:
~/Library/Developer/Xcode/Templates/File\ Templates/
UPDATE: I decided to write a script that would extract the built in Xcode templates and replace the headers. Source and instructions can be found at the following url:
