GPL, COPYING file

[Paolo Ciarrocchi]

Hi all,
a friend of mine wants to release a CMS under GPLv3.
We disagree on how the licence should be inserted in the package.

I think, please correct me if I'm wrong, that the only think he should do
is to put the licence in a COPYING file (which will be part of the package) and
optionally add to the header of every single file the following lines:
-- 
Copyright (C) yyyy  nome dell'autore

I think this is optional even because a lot of gpl software (Linuk
kernel, GIT, mercurial etc etc)
just add the COPYNG file.

My friend believe that he should add the whole licence to every single
file of the package.

Can you please clarify?

Thanks a lot in advance.

Ciao,
