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.
