So if I had something like:
// Copyright __YEAR__ The __PROJECT__ Authors.  All Rights Reserved.
// Use of this source code is governed by a __LICENSE__
// license that can be found in the LICENSE file.

Is that good enough?
Looking at src/nsterm.m as an example, it also doesn't have a copy of the
GPL but a long reference to it plus some surrounding explanation.

Isn't this almost the same reference-only licensing header?
