Manual mode updating
GNU Emacs is not in the public domain; it is copyrighted and there are restrictions on its distribution, but these restrictions are designed to permit everything that a good cooperating citizen would want to do.
What is not allowed is to try to prevent others from further sharing any version of GNU Emacs that they might get from you.
If you have access to the Internet, you can get the latest distribution version of GNU Emacs by anonymous FTP; see on our website for more information.
You may also receive GNU Emacs when you buy a computer.
In other words, the program must be free for you when you get it, not just free for the manufacturer.
If you find GNU Emacs useful, please send a donation to the Free Software Foundation to support our work. The income from sales goes to support the foundation’s purpose: the development of new free software, and improvements to our existing programs including GNU Emacs.
