The programs currently being distributed that relate to Texinfo include
makeinfo, info, texindex, and texinfo.tex.
These programs are free; this means that everyone is free to use
them and free to redistribute them on a free basis. The Texinfo-related
programs 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 programs that relate to Texinfo, that you receive source code or else can get it if you want it, that you can change these programs 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 the Texinfo related programs, 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 the programs that relate to Texinfo. If these programs 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 programs currently being distributed that relate to Texinfo are found in the General Public Licenses that accompany them. This manual specifically is covered by the GNU Free Documentation License (see GNU Free Documentation License).
