When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These
restrictions translate to certain responsibilities for you if you distribute copies of the library, or if you modify it.
For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You
must make sure that they, too, receive or can get the source code. If you link a program with the library, you must provide complete object
files to the recipients so that they can relink them with the library after making changes to the library and recompiling it. And you must show
them these terms so they know their rights.
Our method of protecting your rights has two steps: (1) copyright the library, and (2) offer you this license, which gives you legal permission to
copy, distribute and/or modify the library.
Also, for each distributor's protection, we want to make certain that everyone understands that there is no warranty for this free library. If the
library is modified by someone else and passed on, we want its recipients to know that what they have is not the original version, so that any
problems introduced by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that companies distributing free software
will individually obtain patent licenses, thus in effect transforming the program into proprietary software. To prevent this, we have made it clear
that any patent must be licensed for everyone's free use or not licensed at all.
Most GNU software, including some libraries, is covered by the ordinary GNU General Public License, which was designed for utility
programs. This license, the GNU Library General Public License, applies to certain designated libraries. This license is quite different from the
ordinary one; be sure to read it in full, and don't assume that anything in it is the same as in the ordinary license.
The reason we have a separate public license for some libraries is that they blur the distinction we usually make between modifying or adding
to a program and simply using it. Linking a program with a library, without changing the library, is in some sense simply using the library, and
is analogous to running a utility program or application program. However, in a textual and legal sense, the linked executable is a combined
work, a derivative of the original library, and the ordinary General Public License treats it as such.
Because of this blurred distinction, using the ordinary General Public License for libraries did not effectively promote software sharing,
because most developers did not use the libraries. We concluded that weaker conditions might promote sharing better.
However, unrestricted linking of non-free programs would deprive the users of those programs of all benefit from the free status of the libraries
themselves. This Library General Public License is intended to permit developers of non-free programs to use free libraries, while preserving
your freedom as a user of such programs to change the free libraries that are incorporated in them. (We have not seen how to achieve this as
regards changes in header files, but we have achieved it as regards changes in the actual functions of the Library.) The hope is that this will
lead to faster development of free libraries.
The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work
based on the library" and a "work that uses the library". The former contains code derived from the library, while the latter only works together
with the library.
Note that it is possible for a library to be covered by the ordinary General Public License rather than by this special one.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library which contains a notice placed by the copyright holder or other authorized party
saying it may be distributed under the terms of this Library General Public License (also called "this License"). Each licensee is addressed as
"you".
A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use
some of those functions and data) to form executables.
