10 Copying

GNU Wget is licensed under the GNU General Public License (GNU GPL), which makes it free software. Please note that “free” in “free software” refers to liberty, not price. As some people like to point out, it's the “free” of “free speech”, not the “free” of “free beer”.

The exact and legally binding distribution terms are spelled out below. The GPL guarantees that you have the right (freedom) to run and change GNU Wget and distribute it to others, and even—if you want—charge money for doing any of those things. With these rights comes the obligation to distribute the source code along with the software and to grant your recipients the same rights and impose the same restrictions.

This licensing model is also known as open source because it, among other things, makes sure that all recipients will receive the source code along with the program, and be able to improve it. The GNU project prefers the term “free software” for reasons outlined at http://www.gnu.org/philosophy/free-software-for-freedom.html.

The exact license terms are defined by this paragraph and the GNU General Public License it refers to:

GNU Wget 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 2 of the License, or (at your option) any later version.
