Please specify license clearer

[karllinden]

I would like to package this software for personal use downstream in Gentoo, but the current licensing terms are unclear. The mpd-notification.c file says:

/*
 * (C) 2011-2018 by Christian Hesse <mail@eworm.de>
 *
 * This software may be used and distributed according to the terms
 * of the GNU General Public License, incorporated herein by reference.
 */

without specifying exactly which version of the GPL that is mentioned. Is it GPL-2.0 only, or GPL-2.0 or any later version, or GPL-3.0?

Furthermore, according to [1] (under "The licenses notices") the source file should have a license notice which should not be on the above form but instead something like:

/*
 * Copyright (C) 2011-2018 Christian Hesse <mail@eworm.de>
 *
 * This program is free software: you can redistribute it and/or modify
 * it under the terms of the GNU General Public License as published by
 * the Free Software Foundation, either version 3 of the License, or
 * (at your option) any later version.

 * This program is distributed in the hope that it will be useful,
 * but WITHOUT ANY WARRANTY; without even the implied warranty of
 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
 * GNU General Public License for more details.

 * You should have received a copy of the GNU General Public License
 * along with this program.  If not, see <http://www.gnu.org/licenses/>.
 *
 */

Also, again according to [1] (under "The license files"), there should be a COPYING (or LICENSE) file with the (full) text version of the GPL.

Thanks in advance.
