You should also get your employer (if you work as a
programmer) or your school, if any, to sign a “copyright
disclaimer” for the program, if necessary. Here is a sample;
alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
program ‘Gnomovision’ (which makes passes at compilers)
written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating
your program into proprietary programs. If your program is a
subroutine library, you may consider it more useful to permit
linking proprietary applications with the library. If this is what
you want to do, use the GNU Library General Public License
instead of this License.
=================================================
GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc. 51
Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also
counts as the successor of the GNU Library Public License,
version 2, hence the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General
Public Licenses are intended to guarantee your freedom to
share and change free software-to make sure the software is
free for all its users.
This license, the Lesser General Public License, applies
to some specially designated software packages-typically
libraries--of the Free Software Foundation and other authors
who decide to use it. You can use it too, but we suggest you
first think carefully about whether this license or the ordinary
General Public License is the better strategy to use in any
particular case, based on the explanations below.
When we speak of free software, we are referring to freedom
of use, 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 and use pieces of it in new free programs;
and that you are informed that you can do these things.
To protect your rights, we need to make restrictions that
forbid distributors to deny you these rights or to ask you to
surrender these 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 other code 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.
We protect your rights with a two-step method: (1) we
copyright the library, and (2) we offer you this license, which
gives you legal permission to copy, distribute and/or modify
the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library
is modified by someone else and passed on, the recipients
should know that what they have is not the original version,
so that the original author’s reputation will not be affected by
problems that might be introduced by others.
Finally, software patents pose a constant threat to the
existence of any free program. We wish to make sure that
a company cannot effectively restrict the users of a free
program by obtaining a restrictive license from a patent holder.
Therefore, we insist that any patent license obtained for a
version of the library must be consistent with the full freedom
of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU
Lesser General Public License, applies to certain designated
libraries, and is quite different from the ordinary General
Public License. We use this license for certain libraries in order
to permit linking those libraries into non-free programs.
When a program is linked with a library, whether statically or
using a shared library, the combination of the two is legally
speaking a combined work, a derivative of the original library.
The ordinary General Public License therefore permits such
linking only if the entire combination fits its criteria of freedom.
The Lesser General Public License permits more lax criteria for
linking other code with the library.
We call this license the “Lesser” General Public License
because it does Less to protect the user’s freedom than the
ordinary General Public License. It also provides other free
software developers Less of an advantage over competing
non-free programs. These disadvantages are the reason we
use the ordinary General Public License for many libraries.
However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need
to encourage the widest possible use of a certain library, so
that it becomes a de-facto standard. To achieve this, non-free
programs must be allowed to use the library. A more frequent
case is that a free library does the same job as widely used
non-free libraries. In this case, there is little to gain by limiting
the free library to free software only, so we use the Lesser
General Public License.
In other cases, permission to use a particular library in non-
free programs enables a greater number of people to use a
large body of free software. For example, permission to use
the GNU C Library in non-free programs enables many more
people to use the whole GNU operating system, as well as its
variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less protective
of the users’ freedom, it does ensure that the user of a
program that is linked with the Library has the freedom and
the wherewithal to run that program using a modified version
of the Library.
