Appendix E
Software End User License Agreement

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.
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.
Activities  other  than  copying,  distribution  and 
modification are not covered by this License; they are 
outside its scope. The act of running a program using 
the Library is not  restricted, and output from such a 
program  is  covered  only  if  its  contents  constitute  a 
work  based  on  the  Library  (independent  of  the  use 
of the Library in a tool for writing it). Whether that is 
true depends on what the Library does and what the 
program that uses the Library does.
1.  You  may  copy  and distribute verbatim  copies  of the 
Library’s  complete  source  code  as  you  receive  it,  in 
any  medium,  provided  that  you  conspicuously  and 
appropriately  publish  on  each  copy  an  appropriate 
copyright  notice  and  disclaimer  of  warranty;  keep 
intact all the notices that refer to this License and to 
the absence of any warranty; and distribute a copy of 
this License along with the Library.
You may charge a fee for the physical act of transferring 
a  copy,  and  you  may  at  your  option  offer  warranty 
protection in exchange for a fee.
2.  You may modify your copy or copies of the Library or 
any portion  of  it, thus  forming  a work based  on the 
Library,  and  copy  and  distribute  such  modifications 
or work under the terms of Section 1 above, provided 
that you also meet all of these conditions:
a)  The  modified  work  must  itself  be  a  software 
library.
b)  You  must  cause  the  files  modified  to  carry 
prominent  notices  stating  that  you  changed  the 
files and the date of any change.
c)  You  must  cause  the  whole  of  the  work  to  be 
licensed at no charge to all third parties under the 
terms of this License.
d)  If a facility in the modified Library refers to a function 
or a table of data to be supplied by an application 
program  that  uses  the  facility,  other  than  as  an 
argument passed when the facility is invoked, then 
you must make a good faith effort to ensure that, 
in the event an application does not supply such 
function  or  table,  the  facility  still  operates,  and 
performs  whatever  part  of  its  purpose  remains 
meaningful.
