+<title>GPL-x vs GPL-x+</title>
+FSF licenses (GPL, LGPL, AGPL, FDL) occur in two variants: the 'vN only'
+and 'vN or later' variants. In Gentoo, the licenses of the latter variants
+are denoted by appending
+a plus sign (+) to their respective license notations of the former variant,
+e.g. <c>GPL-2+</c> and <c>GPL-2</c>.
+Determining the correct variant usually requires looking for copyright
+notices in the code. For example, the following copyright notice
+indicates <c>GPL-2+</c> license:
+ * This program is free software; you can redistribute it and/or
+ * modify it under the terms of the GNU General Public License as

+ * the License, or (at your option) any later version.
