OUR NOTICE AND TERMS AND CONDITIONS OF THE GNU GENERAL PUBLIC LICENSE  

Our Preamble Notice 

A. This notice is required to be provided under our contract with the U.S. 
Department of Energy (DOE). This work was produced at the Lawrence 
Livermore National Laboratory under Contract No. DE-AC52-07NA27344 
with the DOE.  

B. Neither the United States Government nor Lawrence Livermore National Security, 
LLC nor any of their employees, makes any warranty, express or implied, or assumes 
any liability or responsibility for the accuracy, completeness, or usefulness of any 
information, apparatus, product, or process disclosed, or represents that its use would 
not infringe privately-owned rights.  

C. Also, reference herein to any specific commercial products, process, or services by 
trade name, trademark, manufacturer or otherwise does not necessarily constitute or 
imply its endorsement, recommendation, or favoring by the United States Government 
or Lawrence Livermore National Security, LLC. The views and opinions of authors 
expressed herein do not necessarily state or reflect those of the United States 
Government or Lawrence Livermore National Security, LLC, and shall not be used for 
advertising or product endorsement purposes.  

The precise terms and conditions for copying, distribution and modification 
follows.  


GNU Terms and Conditions for Copying, Distribution, and Modification 

0. 	This License applies to any program or other work which contains a notice 
placed by the copyright holder saying it may be distributed under the terms of this 
General Public License. The “Program,” below, refers to any such program or work, and 
a “work based on the Program” means either the Program or any derivative work under 
copyright law: that is to say, a work containing the Program or a portion of it, either 
verbatim or with modifications and/or translated into another language.  (Hereinafter, 
translation is included without limitation in the term “modification”.) Each licensee is 
addressed as “you.”  

Activities other than copying, distribution and modification are not covered by 
this License; they are outside its scope. The act of running the Program is not restricted, 
and the output from the Program is covered only if its contents constitute a work based 
on the Program (independent of having been made by running the Program). Whether 
that is true depends on what the Program does.  

1. 	You may copy and distribute verbatim copies of the Program’s 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 
give any other recipients of the Program a copy of this License along with the Program. 

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 Program or any portion of it, thus 
forming a work based on the Program, 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) You must cause the modified files to carry prominent notices stating 
	that you changed the files and the date of any change.  

	b) You must cause any work that you distribute or publish, that in whole 
	or in part contains or is derived from the Program or any part thereof, to 
	be licensed as a whole at no charge to all third parties under the terms of 
	this License.  
	
	c) If the modified program normally reads commands interactively when 
	run, you must cause it, when started running for such interactive use in 
	the most ordinary way, to print or display an announcement including an 
	appropriate copyright notice and a notice that there is no warranty (or 
	else, saying that you provide a warranty) and that users may redistribute 
	the program under these conditions, and telling the user how to view a 
	copy of this License. (Exception: if the Program itself is interactive but 
	does not normally print such an announcement, your work based on the 
	Program is not required to print an announcement.)  
	
These requirements apply to the modified work as a whole.  If identifiable sections of 
that work are not derived from the Program, and can be reasonably considered 
independent and separate works in themselves, then this License, and its terms, do not 
apply to those sections when you distribute them as separate work. But when you 
distribute the same section as part of a whole which is a work based on the Program, the 
distribution of the whole must be on the terms of this License, whose permissions for 
other licensees extend to the entire whole, and thus to each and every part regardless of 
who wrote it.  

Thus, it is not the intent of this section to claim rights or contest your rights to work 
written entirely by you; rather, the intent is to exercise the right to control the 
distribution of derivative or collective works based on the Program.  

In addition, mere aggregation of another work not based on the Program with the 
Program (or with a work based on the Program) on a volume of a storage or distribution 
medium does not bring the other work under the scope of this License.  

3. You may copy and distribute the Program (or a work based on it, under Section 2) in 
object code or executable form under the terms of Sections 1 and 2 above provided that 
you also do one of the following:  

	a) Accompany it with the complete corresponding machine-readable 
	source code, which must be distributed under the terms of Sections 1 and 
	2 above on a medium customarily used for software interchange; or,  
	
	b) Accompany it with a written offer, valid for at least three years, to give 
	any third party, for a charge no more than your cost of physically 
	performing source distribution, a complete machine-readable copy of the 
	corresponding source code, to be distributed under the terms of Sections 1 
	and 2 above on a medium customarily used for software interchange; or,  

	c) Accompany it with the information you received as to the offer to 
	distribute corresponding source code. (This alternative is allowed only for 
	noncommercial distribution and only if you received the program in object 
	code or executable form with such an offer, in accord with Subsection b 
	above.)  
	
The source code for a work means the preferred form the work for making 
modifications to it. For an executable work, 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 executable. 
However, as a special exception, the source code distributed need not include 
anything that is normally distributed (in either source or binary form) with the 
major components (compiler, kernel, and so on) of the operating system on which 
the executable runs, unless that component itself accompanies the executable.  

If distribution of executable or object code is made by offering access to copy 
from a designated place, then offering equivalent access to copy the source code 
from the same place counts as distribution of the source code, even though third 
parties are not compelled to copy the source along with the object code.  

4. 	You may not copy, modify, sublicense, or distribute the Program except as 
expressly provided under this License. Any attempt otherwise to copy, modify, 
sublicense or distribute the Program is void, and will automatically terminate your 
rights under this License.  However, parties who have received copies, or rights, 
from you under this License will not have their licenses terminated so long as such 
parties remain in full compliance.  

5. 	You are not required to accept this License, since you have not signed it. 
However, nothing else grants you permission to modify or distribute the Program or its 
derivative works. These actions are prohibited by law if you do not accept this License. 
Therefore, by modifying or distributing the Program (or any work based on the 
Program), you indicate your acceptance of this License to do so, and all its terms and 
conditions for copying, distributing or modifying the Program or works based on it.  

6. 	Each time you redistribute the Program (or any work based on the Program), the 
recipient automatically receives a license from the original licensor to copy, distribute or 
modify the Program subject to these terms and conditions. You may not impose any 
further restrictions on the recipients’ exercise of the rights granted herein. You are not 
responsible for enforcing compliance by third parties to this License.  

7. 	If, as a consequence of a court judgment or allegation of patent infringement or 
for any other reason (not limited to patent issues), conditions are imposed on you 
(whether by court order, agreement or otherwise) that contradict the conditions of this 
License, they do not excuse you from the conditions of this License. If you cannot 
distribute so as to satisfy simultaneously your obligations under this License and any 
other pertinent obligations, then as a consequence you may not distribute the Program 
at all. For example, if a patent license would not permit royalty-free redistribution of the 
Program by all those who receive copies directly or indirectly through you, then the 
only way you could satisfy both it and this License would be to refrain entirely from 
distribution of the Program.  

If any portion of this section is held invalid or unenforceable under any particular 
circumstance, the balance of the section is intended to apply and the section as a 
whole is intended to apply in other circumstances.  

It is not the purpose to this section to induce you to infringe any patents or other 
property right claims or to contest validity of any such claims; this section has the sole 
purpose of protecting the integrity of the free software distribution system, which is 
implemented by public license practices.  Many people have made generous 
contributions to the wide range of software distributed through that system in reliance 
on consistent application of that system; it is up to the author/donor to decide if he or 
she is willing to distribute software through any other system and a licensee cannot 
impose that choice.  

This section is intended to make thoroughly clear what is believed to be a consequence 
of the rest of this License.  

8.	If the distribution and/or use of the Program is restricted in certain countries 
either by patents or by copyrighted interfaces, the original copyright holder who places 
the Program under this License may add an explicit geographical distribution limitation 
excluding those countries, so that distribution is permitted only in or among countries 
not thus excluded. In such case, this License incorporates the limitation as if written in 
the body of this License.  

9. The Free Software Foundation may publish revised and/or new versions of the 
General Public License from time to time. Such new versions will be similar in spirit to 
the present version, but may differ in detail to address new problems or concerns.  

Each version is given a distinguishing version number.  If the Program specifies a 
version number of this License which applies to it and “any later version,” you have the 
option of following the terms and conditions either of that version of any later version 
published by the Free Software Foundation. If the Program does not specify a version 
number of this License, you may choose any version ever published by the Free 
Software Foundation.  

10.	If you wish to incorporate parts of the Program into other free programs whose 
distribution conditions are different, write to the author to ask for permission. For 
software which is copyrighted by the Free Software Foundation, write to the Free 
Software Foundation; we sometimes make exceptions for this. Our decision to grant 
permission will be guided by the two goals of preserving the free status of all 
derivatives of our free software and or promoting the sharing and reuse of software 
generally.  
 

NO WARRANTY  

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO 
WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE 
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT 
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT 
NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND 
FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY 
AND PERFORMANCE OF   THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE 
DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR 
OR CORRECTION.  

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO 
IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO 
MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, 
BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL 
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR 
INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH 
ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN 
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
