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
