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 
 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

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

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
