auctex: Copying

 
 Copying
 *******
 
 AUCTeX primarily consists of Lisp files for Emacs, but there are also
 installation scripts and files and TeX support files.  All of those are
 "free"; this means that everyone is free to use them and free to
 redistribute them on a free basis.  The files of AUCTeX are not in the
 public domain; they are copyrighted and there are restrictions on their
 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 these
 programs that they might get from you.
 
    Specifically, we want to make sure that you have the right to give
 away copies of the files that constitute AUCTeX, that you receive source
 code or else can get it if you want it, that you can change these files
 or use pieces of them in new free programs, and that you know you can do
 these things.
 
    To make sure that everyone has such rights, we have to forbid you to
 deprive anyone else of these rights.  For example, if you distribute
 copies of parts of AUCTeX, you must give the recipients all the rights
 that you have.  You must make sure that they, too, receive or can get
 the source code.  And you must tell them their rights.
 
    Also, for our own protection, we must make certain that everyone
 finds out that there is no warranty for AUCTeX.  If any parts are
 modified by someone else and passed on, we want their recipients to know
 that what they have is not what we distributed, so that any problems
 introduced by others will not reflect on our reputation.
 
    The precise conditions of the licenses for the files currently being
 distributed as part of AUCTeX are found in the General Public Licenses
 that accompany them.  This manual specifically is covered by the GNU
 Free Documentation License (SeeCopying this Manual).
