 +                    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.
 +
 +                    GNU GENERAL PUBLIC LICENSE
 +   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.
 +
 +                     END OF TERMS AND CONDITIONS
 +
 +            How to Apply These Terms to Your New Programs
 +
 +  If you develop a new program, and you want it to be of the greatest
 +possible use to the public, the best way to achieve this is to make it
 +free software which everyone can redistribute and change under these terms.
 +
 +  To do so, attach the following notices to the program. ​ It is safest
 +to attach them to the start of each source file to most effectively
 +convey the exclusion of warranty; and each file should have at least
 +the "​copyright"​ line and a pointer to where the full notice is found.
 +
 +    <one line to give the program'​s name and a brief idea of what it does.>
 +    Copyright (C) <​year> ​ <name of author>
 +
 +    This program is free software; you can redistribute it and/or modify
 +    it under the terms of the GNU General Public License as published by
 +    the Free Software Foundation; either version 2 of the License, or
 +    (at your option) any later version.
 +
 +    This program is distributed in the hope that it will be useful,
 +    but WITHOUT ANY WARRANTY; without even the implied warranty of
 +    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. ​ See the
 +    GNU General Public License for more details.
 +
 +    You should have received a copy of the GNU General Public License along
 +    with this program; if not, write to the Free Software Foundation, Inc.,
 +    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
 +
 +Also add information on how to contact you by electronic and paper mail.
 +
 +If the program is interactive,​ make it output a short notice like this
 +when it starts in an interactive mode:
 +
 +    Gnomovision version 69, Copyright (C) year name of author
 +    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
 +    This is free software, and you are welcome to redistribute it
 +    under certain conditions; type `show c' for details.
 +
 +The hypothetical commands `show w' and `show c' should show the appropriate
 +parts of the General Public License. ​ Of course, the commands you use may
 +be called something other than `show w' and `show c'; they could even be
 +mouse-clicks or menu items--whatever suits your program.
 +
 +You should also get your employer (if you work as a programmer) or your
 +school, if any, to sign a "​copyright disclaimer"​ for the program, if
 +necessary. ​ Here is a sample; alter the names:
 +
 +  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
 +  `Gnomovision'​ (which makes passes at compilers) written by James Hacker.
 +
 +  <​signature of Ty Coon>, 1 April 1989
 +  Ty Coon, President of Vice
 +
 +This General Public License does not permit incorporating your program into
 +proprietary programs. ​ If your program is a subroutine library, you may
 +consider it more useful to permit linking proprietary applications with the
 +library. ​ If this is what you want to do, use the GNU Lesser General
 +Public License instead of this License.
