GNAT Modified General Public Licence

Commonly known as the GMGPL, the "GNAT Modified General Public License" is identical to the GNU GPL v3 Licence except that it adds the following clause to the terms and conditions of the licence, the basic idea is to ensure that there is no ambiguity for those that want to build commercial tools or other closed source software using the GPL V3, and no danger of the GPL unintentionally taking ownership of other code via the "derivative works" clause.
