GNU GENERAL PUBLIC LICENSE
Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.  
51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.

Preamble
The licenses for most software are designed to take away your freedom to 
share and change it. By contrast, the GNU General Public License is 
intended to guarantee your freedom to share and change free software--to 
make sure the software is free for all its users. This General Public 
License applies to most of the Free Software Foundation's software and to 
any other program whose authors commit to using it. (Some other Free 
Software Foundation software is covered by the GNU Lesser General Public 
License instead.) You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our 
General Public Licenses are designed to make sure that you have the freedom 
to distribute copies of free software (and charge for this service if you 
wish), that you receive source code or can get it if you want it, that you 
can change the software or use pieces of it in new free programs; and that 
you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to 
deny you these rights or to ask you to surrender the rights. These 
restrictions translate to certain responsibilities for you if you 
distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis or 
for a fee, you must give the recipients all the rights that you have. You 
must make sure that they, too, receive or can get the source code. And you 
must show them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and (2) 
offer you this license which gives you legal permission to copy, distribute 
and/or modify the software.

Also, for each author's protection and ours, we want to make certain that 
everyone understands that there is no warranty for this free software. If 
the software is modified by someone else and passed on, we want its 
recipients to know that what they have is not the original, so that any 
problems introduced by others will not reflect on the original authors' 
reputations.

Finally, any free program is threatened constantly by software patents. We 
wish to avoid the danger that redistributors of a free program will 
individually obtain patent licenses, in effect making the program 
proprietary. To prevent this, we have made it clear that any patent must be 
licensed for everyone's free use or not licensed at all.

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

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 works. But when you distribute the same 
  sections 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 of 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 of 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 or 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 will be guided by the two goals of 
  preserving the free status of all derivatives of our free software and of 
  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.

CC0 1.0 Universal License

Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer 
exclusive Copyright and Related Rights (defined below) upon the creator and 
subsequent owner(s) (each and all, an "owner") of an original work of 
authorship and/or a database (each, a "Work").

Certain owners wish to permanently relinquish those rights to a Work for 
the purpose of contributing to a commons of creative, cultural and 
scientific works ("Commons") that the public can reliably and without fear 
of later claims of infringement build upon, modify, incorporate in other 
works, reuse and redistribute as freely as possible in any form whatsoever 
and for any purposes, including without limitation commercial purposes. 
These owners may contribute to the Commons to promote the ideal of a free 
culture and the further production of creative, cultural and scientific 
works, or to gain reputation or greater distribution for their Work in part 
through the use and efforts of others.

For these and/or other purposes and motivations, and without any 
expectation of additional consideration or compensation, the person 
associating CC0 with a Work (the "Affirmer"), to the extent that he or she 
is an owner of Copyright and Related Rights in the Work, voluntarily elects 
to apply CC0 to the Work and publicly distribute the Work under its terms, 
with knowledge of his or her Copyright and Related Rights in the Work and 
the meaning and intended legal effect of CC0 on those rights.

1. Copyright and Related Rights. A Work made available under CC0 may be 
  protected by copyright and related or neighboring rights ("Copyright and 
  Related Rights"). Copyright and Related Rights include, but are not limited 
  to, the following:

  the right to reproduce, adapt, distribute, perform, display, communicate, 
  and translate a Work;
  moral rights retained by the original author(s) and/or performer(s);
  publicity and privacy rights pertaining to a person's image or likeness 
  depicted in a Work;
  rights protecting against unfair competition in regards to a Work, subject 
  to the limitations in paragraph 4(a), below;
  rights protecting the extraction, dissemination, use and reuse of data in a 
  Work;
  database rights (such as those arising under Directive 96/9/EC of the 
  European Parliament and of the Council of 11 March 1996 on the legal 
  protection of databases, and under any national implementation thereof, 
  including any amended or successor version of such directive); and
  other similar, equivalent or corresponding rights throughout the world 
  based on applicable law or treaty, and any national implementations thereof.

2. Waiver. To the greatest extent permitted by, but not in contravention 
  of, applicable law, Affirmer hereby overtly, fully, permanently, 
  irrevocably and unconditionally waives, abandons, and surrenders all of 
  Affirmer's Copyright and Related Rights and associated claims and causes of 
  action, whether now known or unknown (including existing as well as future 
  claims and causes of action), in the Work (i) in all territories worldwide, 
  (ii) for the maximum duration provided by applicable law or treaty 
  (including future time extensions), (iii) in any current or future medium 
  and for any number of copies, and (iv) for any purpose whatsoever, 
  including without limitation commercial, advertising or promotional 
  purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each 
  member of the public at large and to the detriment of Affirmer's heirs and 
  successors, fully intending that such Waiver shall not be subject to 
  revocation, rescission, cancellation, termination, or any other legal or 
  equitable action to disrupt the quiet enjoyment of the Work by the public 
  as contemplated by Affirmer's express Statement of Purpose.

3. Public License Fallback. Should any part of the Waiver for any reason be 
  judged legally invalid or ineffective under applicable law, then the Waiver 
  shall be preserved to the maximum extent permitted taking into account 
  Affirmer's express Statement of Purpose. In addition, to the extent the 
  Waiver is so judged Affirmer hereby grants to each affected person a 
  royalty-free, non transferable, non sublicensable, non exclusive, 
  irrevocable and unconditional license to exercise Affirmer's Copyright and 
  Related Rights in the Work (i) in all territories worldwide, (ii) for the 
  maximum duration provided by applicable law or treaty (including future 
  time extensions), (iii) in any current or future medium and for any number 
  of copies, and (iv) for any purpose whatsoever, including without 
  limitation commercial, advertising or promotional purposes (the "License"). 
  The License shall be deemed effective as of the date CC0 was applied by 
  Affirmer to the Work. Should any part of the License for any reason be 
  judged legally invalid or ineffective under applicable law, such partial 
  invalidity or ineffectiveness shall not invalidate the remainder of the 
  License, and in such case Affirmer hereby affirms that he or she will not 
  (i) exercise any of his or her remaining Copyright and Related Rights in 
  the Work or (ii) assert any associated claims and causes of action with 
  respect to the Work, in either case contrary to Affirmer's express 
  Statement of Purpose.

4. Limitations and Disclaimers.

  No trademark or patent rights held by Affirmer are waived, abandoned, 
  surrendered, licensed or otherwise affected by this document.
  Affirmer offers the Work as-is and makes no representations or warranties 
  of any kind concerning the Work, express, implied, statutory or otherwise, 
  including without limitation warranties of title, merchantability, fitness 
  for a particular purpose, non infringement, or the absence of latent or 
  other defects, accuracy, or the present or absence of errors, whether or 
  not discoverable, all to the greatest extent permissible under applicable 
  law.
  Affirmer disclaims responsibility for clearing rights of other persons that 
  may apply to the Work or any use thereof, including without limitation any 
  person's Copyright and Related Rights in the Work. Further, Affirmer 
  disclaims responsibility for obtaining any necessary consents, permissions 
  or other rights required for any use of the Work.
  Affirmer understands and acknowledges that Creative Commons is not a party 
  to this document and has no duty or obligation with respect to this CC0 or 
  use of the Work.
