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 Lesser General Public License instead of this License.

GNU LESSER GENERAL PUBLIC LICENSE

Version 2.1, February 1999
Copyright © 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.

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,
whereas the latter must be combined with the library in order to run.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0.

This License Agreement applies to any software library or other program which
contains a notice placed by the copyright holder or other authorized party saying
it may be distributed under the terms of this Lesser 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.
The “Library”, below, refers to any such software library or work which has been
distributed under these terms. A “work based on the Library” means either the
Library or any derivative work under copyright law: that is to say, a work
containing the Library or a portion of it, either verbatim or with modifications
and/or translated straightforwardly into another language. (Hereinafter,
translation is included without limitation in the term “modification”.)
“Source code” for a work means the preferred form of the work for making
modifications to it. For a library, complete source code means all the source
code for all modules it contains, plus any associated interface definition files,
plus the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification are not covered by
this License; they are outside its scope. The act of running a program using
the Library is not restricted, and output from such a program is covered only
if its contents constitute a work based on the Library (independent of the use
of the Library in a tool for writing it). Whether that is true depends on what the
Library does and what the program that uses the Library does.

1.

You may copy and distribute verbatim copies of the Library’s complete source
code as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and disclaimer
of warranty; keep intact all the notices that refer to this License and to the absence
of any warranty; and distribute a copy of this License along with the Library.
You may charge a fee for the physical act of transferring a copy, and you may
at your option offer warranty protection in exchange for a fee.

2.

You may modify your copy or copies of the Library or any portion of it, thus
forming a work based on the Library, and copy and distribute such
modifications or work under the terms of Section 1 above, provided that you
also meet all of these conditions:
a)

The modified work must itself be a software library.

b)

You must cause the files modified to carry prominent notices stating that
you changed the files and the date of any change.

c)

You must cause the whole of the work to be licensed at no charge to all
third parties under the terms of this License.

d)

If a facility in the modified Library refers to a function or a table of data to
be supplied by an application program that uses the facility, other than as
an argument passed when the facility is invoked, then you must make a
good faith effort to ensure that, in the event an application does not
supply such function or table, the facility still operates, and performs
whatever part of its purpose remains meaningful. (For example, a
function in a library to compute square roots has a purpose that is entirely
well-defined independent of the application. Therefore, Subsection 2d
requires that any application-supplied function or table used by this
function must be optional: if the application does not supply it, the square
root function must still compute square roots.)

These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Library, and can be reasonably
considered independent and separate works in themselves, then this License,
and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole
which is a work based on the Library, the distribution of the whole must be on
the terms of this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to
work written entirely by you; rather, the intent is to exercise the right to control
the distribution of derivative or collective works based on the Library.
In addition, mere aggregation of another work not based on the Library with the
Library (or with a work based on the Library) on a volume of a storage or distribution
medium does not bring the other work under the scope of this License.

3.

You may opt to apply the terms of the ordinary GNU General Public License instead
of this License to a given copy of the Library. To do this, you must alter all the notices
that refer to this License, so that they refer to the ordinary GNU General Public
License, version 2, instead of to this License. (If a newer version than version 2 of
the ordinary GNU General Public License has appeared, then you can specify that
version instead if you wish.) Do not make any other change in these notices.
Once this change is made in a given copy, it is irreversible for that copy, so the
ordinary GNU General Public License applies to all subsequent copies and
derivative works made from that copy. This option is useful when you wish to
copy part of the code of the Library into a program that is not a library.

4.

You may copy and distribute the Library (or a portion or derivative of it, under
Section 2) in object code or executable form under the terms of Sections 1 and
2 above provided that you accompany it with the complete corresponding
machine-readable source code, which must be distributed under the terms of
Sections 1 and 2 above on a medium customarily used for software interchange.
If distribution of object code is made by offering access to copy from a designated
place, then offering equivalent access to copy the source code from the same
