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".
