As I've stated, you cannot claim Copyright to the ReactOS foundation
unless EVERY developer that has touched that file agrees to it. This
would require significant administrative resources as well as locating
any previous project members. And that still doesn't guarantee that they
will all agree to give copyright to the foundation. As it stands,
copyright belongs to the actual developers that have written the file.

When some of us unofficially discussed the project header, we determined
it was not a good idea to have a revision entry for 3 simple facts:
1) Waste of space
2) Duplicate information, we have SVN for this
3) Even disregarding the first two reasons, if you look back at when
this was used, almost no developers actually update the revision field.
Few of them even upgrade the "programmer" field. A lot of files have
David Welch in the kernel simply because his original header was copied
everywhere. Developers which actually worked on the file often don't
appear at all. Getting people to update the revisions field would be
even harder. Additionally, it's completely unnecessary since SVN is
there for that (and this was the original argument that was made against

Add it to the coding guidelines I guess.

I suggest something as follows:
* PROJECT: ReactOS Kernel
* LICENSE: GPL - See COPYING in the top level directory
* FILE: ntoskrnl/ex/mutant.c
* PURPOSE: section of the kernel
* PROGRAMMERS: Alex Ionescu (alex at reactos.org)
* David Welch (welch at cwcom.net)
Which is exactly what the kernel uses right now.
