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.
