To do so, attach the following notices to the program. It is safest to attach

them to the start of each source file to most effectively convey the exclusion of

warranty; and each file should have at least the “copyright” line and a pointer to

where the full notice is found.

<one line to give the program’s name and a brief idea of what it does.>

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this when it starts

in an interactive mode:

comes with ABSOLUTELY NO WARRANTY; for details type ‛show w’.

This is free software, and you are welcome to redistribute it under certain

conditions; type ‛show c’ for details.

The hypothetical commands ‛show w’ and ‛show c’ should show the appropriate

parts of the General Public License. Of course, the commands you use may be

called something other than ‛show w’ and ‛show c’; they could even be mouse-

clicks or menu items--whatever suits your program.

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

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 (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.

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.

GNU LESSER GENERAL PUBLIC LICENSE 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.
