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.     
     
 
 
  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
