Firefox is one example.  In every file, you can write something like

 * The contents of this file are subject to the Falcon Programming
 * Language License 1.0 (the "FPLL"); you may not use this file
 * except in compliance with the FPLL. You may obtain a copy of the
 * FPLL at http://www.falconpl.org/?page_id=license
 * Software distributed under the FPLL is distributed on an "AS IS" basis,
 * WITHOUT WARRANTY OF ANY KIND, either express or implied. See the FPLL
 * for the specific language governing rights and limitations under the
 * FPLL.
 * Alternatively, the contents of this file may be used under the
 * terms of the GNU General Public License Version 2 or later (the
 * "GPL"), in which case the provisions of the GPL are applicable
 * instead of those above. If you wish to allow use of your version of
 * this file only under the terms of the GPL, and not to allow others
 * to use your version of this file under the terms of the FPLL,
 * indicate your decision by deleting the provisions above and replace
 * them with the notice and other provisions required by the GPL. If
 * you do not delete the provisions above, a recipient may use your
 * version of this file under the terms of either the FPLL or the GPL.

It would also be nice to put a notice at the top level (e.g. in a
README) that states that the same thing.  Something like

    Copyright 1989-2001, Giancarlo Niccolai  All rights reserved.

    This program is free software; you can redistribute it and/or modify
    it under the terms of either:

    a) the "Falcon Public Language License" which comes with Falcon, or

    b) the GNU General Public License as published by the Free Software
       Foundation; either version 2, or (at your option) any later

Also include a copy of the FPLL and the GPL with the code.
