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".
