3. Legal terms and small print

Mosmake is free software; you can redistribute it and/or modify under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

Mosmake 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.

Since you probably have at least a dozen copies of the GPL lying around already, one is not included in the author's distribution of Mosmake. In the unlikely case that you don't have a copy of the license, or if you're unsure that the copy you have is genuine, check the official source at http://www.gnu.org/licenses/licenses.html#GPL.

The author of Mosmake is not in any way affiliated with the Free Software Foundation, except that he happens to like their license.

The author wishes to assert that he considers it "mere aggregation" if Mosmake is distributed unchanged together with the source code for another piece of software which uses Mosmake in its build process.

This means that you can use Mosmake to build software that is not itself licenced under the GPL: Mosmake is not viral.
