257N/A Everyone is permitted to copy and distribute verbatim copies
257N/A of this license document, but changing it is not allowed.
257N/A The licenses for most software are designed to take away your
257N/Afreedom to share and change it. By contrast, the GNU General Public
257N/ALicense is intended to guarantee your freedom to share and change free
257N/Asoftware--to make sure the software is free for all its users. This
257N/AGeneral Public License applies to most of the Free Software
257N/AFoundation's software and to any other program whose authors commit to
257N/Ausing it. (Some other Free Software Foundation software is covered by
257N/Athe GNU Library General Public License instead.) You can apply it to
257N/A When we speak of free software, we are referring to freedom, not
257N/Aprice. Our General Public Licenses are designed to make sure that you
257N/Ahave the freedom to distribute copies of free software (and charge for
257N/Athis service if you wish), that you receive source code or can get it
257N/Aif you want it, that you can change the software or use pieces of it
257N/Ain new free programs; and that you know you can do these things.
257N/A To protect your rights, we need to make restrictions that forbid
257N/Aanyone to deny you these rights or to ask you to surrender the rights.
257N/AThese restrictions translate to certain responsibilities for you if you
257N/Adistribute copies of the software, or if you modify it.
257N/A For example, if you distribute copies of such a program, whether
257N/Agratis or for a fee, you must give the recipients all the rights that
257N/Ayou have. You must make sure that they, too, receive or can get the
257N/Asource code. And you must show them these terms so they know their
257N/A We protect your rights with two steps: (1) copyright the software, and
257N/A(2) offer you this license which gives you legal permission to copy,
257N/A Also, for each author's protection and ours, we want to make certain
257N/Athat everyone understands that there is no warranty for this free
257N/Asoftware. If the software is modified by someone else and passed on, we
257N/Awant its recipients to know that what they have is not the original, so
257N/Athat any problems introduced by others will not reflect on the original
257N/A Finally, any free program is threatened constantly by software
257N/Apatents. We wish to avoid the danger that redistributors of a free
257N/Aprogram will individually obtain patent licenses, in effect making the
257N/Aprogram proprietary. To prevent this, we have made it clear that any
257N/Apatent must be licensed for everyone's free use or not licensed at all.
257N/A The precise terms and conditions for copying, distribution and
257N/A GNU GENERAL PUBLIC LICENSE
257N/A TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
257N/A 0. This License applies to any program or other work which contains
257N/Aa notice placed by the copyright holder saying it may be distributed
257N/Aunder the terms of this General Public License. The "Program", below,
257N/Arefers to any such program or work, and a "work based on the Program"
257N/Ameans either the Program or any derivative work under copyright law:
257N/Athat is to say, a work containing the Program or a portion of it,
257N/Aeither verbatim or with modifications
and/or translated into another
257N/Alanguage. (Hereinafter, translation is included without limitation in
257N/Athe term "modification".) Each licensee is addressed as "you".
257N/AActivities other than copying, distribution and modification are not
257N/Acovered by this License; they are outside its scope. The act of
257N/Arunning the Program is not restricted, and the output from the Program
257N/Ais covered only if its contents constitute a work based on the
257N/AProgram (independent of having been made by running the Program).
257N/AWhether that is true depends on what the Program does.
257N/A 1. You may copy and distribute verbatim copies of the Program's
257N/Asource code as you receive it, in any medium, provided that you
257N/Aconspicuously and appropriately publish on each copy an appropriate
257N/Acopyright notice and disclaimer of warranty; keep intact all the
257N/Anotices that refer to this License and to the absence of any warranty;
257N/Aand give any other recipients of the Program a copy of this License
257N/AYou may charge a fee for the physical act of transferring a copy, and
257N/Ayou may at your option offer warranty protection in exchange for a fee.
257N/A 2. You may modify your copy or copies of the Program or any portion
257N/Aof it, thus forming a work based on the Program, and copy and
257N/Adistribute such modifications or work under the terms of Section 1
257N/Aabove, provided that you also meet all of these conditions:
257N/A a) You must cause the modified files to carry prominent notices
257N/A stating that you changed the files and the date of any change.
257N/A b) You must cause any work that you distribute or publish, that in
257N/A whole or in part contains or is derived from the Program or any
257N/A part thereof, to be licensed as a whole at no charge to all third
257N/A parties under the terms of this License.
257N/A c) If the modified program normally reads commands interactively
257N/A when run, you must cause it, when started running for such
257N/A interactive use in the most ordinary way, to print or display an
257N/A announcement including an appropriate copyright notice and a
257N/A notice that there is no warranty (or else, saying that you provide
257N/A a warranty) and that users may redistribute the program under
257N/A these conditions, and telling the user how to view a copy of this
257N/A License. (Exception: if the Program itself is interactive but
257N/A does not normally print such an announcement, your work based on
257N/A the Program is not required to print an announcement.)
257N/AThese requirements apply to the modified work as a whole. If
257N/Aidentifiable sections of that work are not derived from the Program,
257N/Aand can be reasonably considered independent and separate works in
257N/Athemselves, then this License, and its terms, do not apply to those
257N/Asections when you distribute them as separate works. But when you
257N/Adistribute the same sections as part of a whole which is a work based
257N/Aon the Program, the distribution of the whole must be on the terms of
257N/Athis License, whose permissions for other licensees extend to the
257N/Aentire whole, and thus to each and every part regardless of who wrote it.
257N/AThus, it is not the intent of this section to claim rights or contest
257N/Ayour rights to work written entirely by you; rather, the intent is to
257N/Aexercise the right to control the distribution of derivative or
257N/Acollective works based on the Program.
257N/AIn addition, mere aggregation of another work not based on the Program
257N/Awith the Program (or with a work based on the Program) on a volume of
257N/Aa storage or distribution medium does not bring the other work under
257N/Athe scope of this License.
257N/A 3. You may copy and distribute the Program (or a work based on it,
257N/Aunder Section 2) in object code or executable form under the terms of
257N/ASections 1 and 2 above provided that you also do one of the following:
257N/A a) Accompany it with the complete corresponding machine-readable
257N/A source code, which must be distributed under the terms of Sections
257N/A 1 and 2 above on a medium customarily used for software interchange; or,
257N/A b) Accompany it with a written offer, valid for at least three
257N/A years, to give any third party, for a charge no more than your
257N/A cost of physically performing source distribution, a complete
257N/A machine-readable copy of the corresponding source code, to be
257N/A distributed under the terms of Sections 1 and 2 above on a medium
257N/A customarily used for software interchange; or,
257N/A c) Accompany it with the information you received as to the offer
257N/A to distribute corresponding source code. (This alternative is
257N/A allowed only for noncommercial distribution and only if you
257N/A received the program in object code or executable form with such
257N/A an offer, in accord with Subsection b above.)
257N/AThe source code for a work means the preferred form of the work for
257N/Amaking modifications to it. For an executable work, complete source
257N/Acode means all the source code for all modules it contains, plus any
257N/Aassociated interface definition files, plus the scripts used to
257N/Acontrol compilation and installation of the executable. However, as a
257N/Aspecial exception, the source code distributed need not include
257N/Aanything that is normally distributed (in either source or binary
257N/Aform) with the major components (compiler, kernel, and so on) of the
257N/Aoperating system on which the executable runs, unless that component
257N/Aitself accompanies the executable.
257N/AIf distribution of executable or object code is made by offering
257N/Aaccess to copy from a designated place, then offering equivalent
257N/Aaccess to copy the source code from the same place counts as
257N/Adistribution of the source code, even though third parties are not
257N/Acompelled to copy the source along with the object code.
257N/A 4. You may not copy, modify, sublicense, or distribute the Program
257N/Aexcept as expressly provided under this License. Any attempt
257N/Aotherwise to copy, modify, sublicense or distribute the Program is
257N/Avoid, and will automatically terminate your rights under this License.
257N/AHowever, parties who have received copies, or rights, from you under
257N/Athis License will not have their licenses terminated so long as such
257N/Aparties remain in full compliance.
257N/A 5. You are not required to accept this License, since you have not
257N/Asigned it. However, nothing else grants you permission to modify or
257N/Adistribute the Program or its derivative works. These actions are
257N/Aprohibited by law if you do not accept this License. Therefore, by
257N/Amodifying or distributing the Program (or any work based on the
257N/AProgram), you indicate your acceptance of this License to do so, and
257N/Aall its terms and conditions for copying, distributing or modifying
257N/Athe Program or works based on it.
257N/A 6. Each time you redistribute the Program (or any work based on the
257N/AProgram), the recipient automatically receives a license from the
257N/Aoriginal licensor to copy, distribute or modify the Program subject to
257N/Athese terms and conditions. You may not impose any further
257N/Arestrictions on the recipients' exercise of the rights granted herein.
257N/AYou are not responsible for enforcing compliance by third parties to
257N/A 7. If, as a consequence of a court judgment or allegation of patent
257N/Ainfringement or for any other reason (not limited to patent issues),
257N/Aconditions are imposed on you (whether by court order, agreement or
257N/Aotherwise) that contradict the conditions of this License, they do not
257N/Aexcuse you from the conditions of this License. If you cannot
257N/Adistribute so as to satisfy simultaneously your obligations under this
257N/ALicense and any other pertinent obligations, then as a consequence you
257N/Amay not distribute the Program at all. For example, if a patent
257N/Alicense would not permit royalty-free redistribution of the Program by
257N/Aall those who receive copies directly or indirectly through you, then
257N/Athe only way you could satisfy both it and this License would be to
257N/Arefrain entirely from distribution of the Program.
257N/AIf any portion of this section is held invalid or unenforceable under
257N/Aany particular circumstance, the balance of the section is intended to
257N/Aapply and the section as a whole is intended to apply in other
257N/AIt is not the purpose of this section to induce you to infringe any
257N/Apatents or other property right claims or to contest validity of any
257N/Asuch claims; this section has the sole purpose of protecting the
257N/Aintegrity of the free software distribution system, which is
257N/Aimplemented by public license practices. Many people have made
257N/Agenerous contributions to the wide range of software distributed
257N/Athrough that system in reliance on consistent application of that
257N/Ato distribute software through any other system and a licensee cannot
257N/AThis section is intended to make thoroughly clear what is believed to
257N/Abe a consequence of the rest of this License.
257N/A 8. If the distribution
and/or use of the Program is restricted in
257N/Acertain countries either by patents or by copyrighted interfaces, the
257N/Aoriginal copyright holder who places the Program under this License
257N/Amay add an explicit geographical distribution limitation excluding
257N/Athose countries, so that distribution is permitted only in or among
257N/Acountries not thus excluded. In such case, this License incorporates
257N/Athe limitation as if written in the body of this License.
257N/A 9. The Free Software Foundation may publish revised
and/or new versions
257N/Aof the General Public License from time to time. Such new versions will
257N/Abe similar in spirit to the present version, but may differ in detail to
257N/Aaddress new problems or concerns.
257N/AEach version is given a distinguishing version number. If the Program
257N/Aspecifies a version number of this License which applies to it and "any
257N/Alater version", you have the option of following the terms and conditions
257N/Aeither of that version or of any later version published by the Free
257N/ASoftware Foundation. If the Program does not specify a version number of
257N/Athis License, you may choose any version ever published by the Free Software
257N/A 10. If you wish to incorporate parts of the Program into other free
257N/Aprograms whose distribution conditions are different, write to the author
257N/Ato ask for permission. For software which is copyrighted by the Free
257N/ASoftware Foundation, write to the Free Software Foundation; we sometimes
257N/Amake exceptions for this. Our decision will be guided by the two goals
257N/Aof preserving the free status of all derivatives of our free software and
257N/Aof promoting the sharing and reuse of software generally.
257N/A 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
257N/AFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
257N/AOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES
257N/APROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
257N/AOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
257N/AMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
257N/ATO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
257N/APROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
257N/A 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
257N/AWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR 257N/AREDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
257N/AINCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
257N/AOUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
257N/ATO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
257N/AYOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
257N/APROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
257N/APOSSIBILITY OF SUCH DAMAGES.
257N/A END OF TERMS AND CONDITIONS
257N/A How to Apply These Terms to Your New Programs
257N/A If you develop a new program, and you want it to be of the greatest
257N/Apossible use to the public, the best way to achieve this is to make it
257N/Afree software which everyone can redistribute and change under these terms.
257N/A To do so, attach the following notices to the program. It is safest
257N/Ato attach them to the start of each source file to most effectively
257N/Aconvey the exclusion of warranty; and each file should have at least
257N/Athe "copyright" line and a pointer to where the full notice is found.
257N/A <one line to give the program's name and a brief idea of what it does.>
257N/A Copyright (C) <year> <name of author>
257N/A This program is free software; you can redistribute it
and/or modify
257N/A it under the terms of the GNU General Public License as published by
257N/A the Free Software Foundation; either version 2 of the License, or
257N/A (at your option) any later version.
257N/A This program is distributed in the hope that it will be useful,
257N/A but WITHOUT ANY WARRANTY; without even the implied warranty of
257N/A MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
257N/A GNU General Public License for more details.
257N/A You should have received a copy of the GNU General Public License
257N/A along with this program; if not, write to the Free Software
257N/A Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
257N/AAlso add information on how to contact you by electronic and paper mail.
257N/AIf the program is interactive, make it output a short notice like this
257N/Awhen it starts in an interactive mode:
257N/A Gnomovision version 69, Copyright (C) year name of author
257N/A Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
257N/A This is free software, and you are welcome to redistribute it
257N/A under certain conditions; type `show c' for details.
257N/AThe hypothetical commands `show w' and `show c' should show the appropriate
257N/Aparts of the General Public License. Of course, the commands you use may
257N/Abe called something other than `show w' and `show c'; they could even be
257N/Amouse-clicks or menu items--whatever suits your program.
257N/AYou should also get your employer (if you work as a programmer) or your
257N/Aschool, if any, to sign a "copyright disclaimer" for the program, if
257N/Anecessary. Here is a sample; alter the names:
257N/A Yoyodyne, Inc., hereby disclaims all copyright interest in the program

257N/AThis General Public License does not permit incorporating your program into
257N/Aproprietary programs. If your program is a subroutine library, you may
257N/Aconsider it more useful to permit linking proprietary applications with the
257N/Alibrary. If this is what you want to do, use the GNU Library General
257N/APublic License instead of this License.
