Distribution

Af is free software; this means that everyone is free to use it and free to redistribute it on certain conditions. Af 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 af that they might get from you. The precise conditions are found in the GNU General Public License that comes with af and also appears following this section.

The simplest way to get a copy of af is from someone else who has it. You need not ask for permission to do so, or tell anyone you have done so; just copy it. If you have access to the Internet, you can get the latest version, or a patch to upgrade to the latest version, from the Af Home Page on the World Wide Web `http://www.thing.demon.co.uk/af', or by anonymous FTP from `ftp://ftp.csv.warwick.ac.uk/pub/mail/af'.
