I'm talking about something that was much-talked about, and people are probably following some of the suggestions made about this, but I think there should be some sort of standardisation.
Here's the header I use for all my GSoC code:
# vim: set sw=4 sts=4 et :
# Copyright: 2008 Gentoo Foundation
# Author(s): Nirbheek Chauhan <email@example.com>
# License: GPL-2
# Immortal lh!
I encourage all of you to adopt the last two lines in your headers as well :D
