Here's a little a little tool I wrote that automatically generates copyright headers for source files in a git repository based on the git history.

Run it like this:

~/projects/pulseaudio$ copyright.py src/pulsecore/sink.c src/pulsecore/core-util.c

And it will give you this:

File: src/pulsecore/sink.c Copyright 2004, 2006-2009 Lennart Poettering Copyright 2006-2007 Pierre Ossman Copyright 2008-2009 Marc-Andre Lureau File: src/pulsecore/core-util.c Copyright 2004, 2006-2009 Lennart Poettering Copyright 2006-2007 Pierre Ossman Copyright 2008 Stelian Ionescu Copyright 2009 Jared D. McNeill Copyright 2009 Marc-Andre Lureau

This little script could use love from a friendly soul to make it crawl entire source trees and patch in appropriate copyright headers. Anyone up for it?
