tde-packaging build script GPL/Public Domain statement requirement?

Tim, All,

When we last did the build scripts for trinity, Tim suggested that each build script contain reference to the GPL. I had submitted all build scripts for Arch with:

# # All modifications and uses of this file are licensed under # the software for which this file was made for, should the software # be under an Open Source License, at least version 1.9, defined # by the Open Source Initiative. In other cases, this file is automatically # released to the Public Domain. #

I've noticed the current scripts omit the statement. For submitting/updating scripts, is this something that is wanted? If so, does it need to be updated in any way? It could be more readable legally.
