2408N/A Everyone is permitted to copy and distribute verbatim copies
2408N/A of this license document, but changing it is not allowed.
2408N/A The licenses for most software are designed to take away your
2408N/Afreedom to share and change it. By contrast, the GNU General Public
2408N/ALicense is intended to guarantee your freedom to share and change free
2408N/Asoftware--to make sure the software is free for all its users. This
2408N/AGeneral Public License applies to most of the Free Software
2408N/AFoundation's software and to any other program whose authors commit to
2408N/Ausing it. (Some other Free Software Foundation software is covered by
2408N/Athe GNU Library General Public License instead.) You can apply it to
2408N/A When we speak of free software, we are referring to freedom, not
2408N/Aprice. Our General Public Licenses are designed to make sure that you
2408N/Ahave the freedom to distribute copies of free software (and charge for
2408N/Athis service if you wish), that you receive source code or can get it
2408N/Aif you want it, that you can change the software or use pieces of it
2408N/Ain new free programs; and that you know you can do these things.
2408N/A To protect your rights, we need to make restrictions that forbid
2408N/Aanyone to deny you these rights or to ask you to surrender the rights.
2408N/AThese restrictions translate to certain responsibilities for you if you
2408N/Adistribute copies of the software, or if you modify it.
2408N/A For example, if you distribute copies of such a program, whether
2408N/Agratis or for a fee, you must give the recipients all the rights that
2408N/Ayou have. You must make sure that they, too, receive or can get the
2408N/Asource code. And you must show them these terms so they know their
2408N/A We protect your rights with two steps: (1) copyright the software, and
2408N/A(2) offer you this license which gives you legal permission to copy,
2408N/A Also, for each author's protection and ours, we want to make certain
2408N/Athat everyone understands that there is no warranty for this free
2408N/Asoftware. If the software is modified by someone else and passed on, we
2408N/Awant its recipients to know that what they have is not the original, so
2408N/Athat any problems introduced by others will not reflect on the original
2408N/A Finally, any free program is threatened constantly by software
2408N/Apatents. We wish to avoid the danger that redistributors of a free
2408N/Aprogram will individually obtain patent licenses, in effect making the
2408N/Aprogram proprietary. To prevent this, we have made it clear that any
2408N/Apatent must be licensed for everyone's free use or not licensed at all.
2408N/A The precise terms and conditions for copying, distribution and
2408N/A TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
2408N/A 0. This License applies to any program or other work which contains
2408N/Aa notice placed by the copyright holder saying it may be distributed
2408N/Aunder the terms of this General Public License. The "Program", below,
2408N/Arefers to any such program or work, and a "work based on the Program"
2408N/Ameans either the Program or any derivative work under copyright law:
2408N/Athat is to say, a work containing the Program or a portion of it,
2408N/Aeither verbatim or with modifications
and/or translated into another
2408N/Alanguage. (Hereinafter, translation is included without limitation in
2408N/Athe term "modification".) Each licensee is addressed as "you".
2408N/AActivities other than copying, distribution and modification are not
2408N/Acovered by this License; they are outside its scope. The act of
2408N/Arunning the Program is not restricted, and the output from the Program
2408N/Ais covered only if its contents constitute a work based on the
2408N/AProgram (independent of having been made by running the Program).
2408N/AWhether that is true depends on what the Program does.
2408N/A 1. You may copy and distribute verbatim copies of the Program's
2408N/Asource code as you receive it, in any medium, provided that you
2408N/Aconspicuously and appropriately publish on each copy an appropriate
2408N/Acopyright notice and disclaimer of warranty; keep intact all the
2408N/Anotices that refer to this License and to the absence of any warranty;
2408N/Aand give any other recipients of the Program a copy of this License
2408N/AYou may charge a fee for the physical act of transferring a copy, and
2408N/Ayou may at your option offer warranty protection in exchange for a fee.
2408N/A 2. You may modify your copy or copies of the Program or any portion
2408N/Aof it, thus forming a work based on the Program, and copy and
2408N/Adistribute such modifications or work under the terms of Section 1
2408N/Aabove, provided that you also meet all of these conditions:
2408N/A a) You must cause the modified files to carry prominent notices
2408N/A stating that you changed the files and the date of any change.
2408N/A b) You must cause any work that you distribute or publish, that in
2408N/A whole or in part contains or is derived from the Program or any
2408N/A part thereof, to be licensed as a whole at no charge to all third
2408N/A parties under the terms of this License.
2408N/A c) If the modified program normally reads commands interactively
2408N/A when run, you must cause it, when started running for such
2408N/A interactive use in the most ordinary way, to print or display an
2408N/A announcement including an appropriate copyright notice and a
2408N/A notice that there is no warranty (or else, saying that you provide
2408N/A a warranty) and that users may redistribute the program under
2408N/A these conditions, and telling the user how to view a copy of this
2408N/A License. (Exception: if the Program itself is interactive but
2408N/A does not normally print such an announcement, your work based on
2408N/A the Program is not required to print an announcement.)
2408N/AThese requirements apply to the modified work as a whole. If
2408N/Aidentifiable sections of that work are not derived from the Program,
2408N/Aand can be reasonably considered independent and separate works in
2408N/Athemselves, then this License, and its terms, do not apply to those
2408N/Asections when you distribute them as separate works. But when you
2408N/Adistribute the same sections as part of a whole which is a work based
2408N/Aon the Program, the distribution of the whole must be on the terms of
2408N/Athis License, whose permissions for other licensees extend to the
2408N/Aentire whole, and thus to each and every part regardless of who wrote it.
2408N/AThus, it is not the intent of this section to claim rights or contest
2408N/Ayour rights to work written entirely by you; rather, the intent is to
2408N/Aexercise the right to control the distribution of derivative or
2408N/Acollective works based on the Program.
2408N/AIn addition, mere aggregation of another work not based on the Program
2408N/Awith the Program (or with a work based on the Program) on a volume of
2408N/Aa storage or distribution medium does not bring the other work under
2408N/A 3. You may copy and distribute the Program (or a work based on it,
2408N/Aunder Section 2) in object code or executable form under the terms of
2408N/ASections 1 and 2 above provided that you also do one of the following:
2408N/A a) Accompany it with the complete corresponding machine-readable
2408N/A source code, which must be distributed under the terms of Sections
2408N/A 1 and 2 above on a medium customarily used for software interchange; or,
2408N/A b) Accompany it with a written offer, valid for at least three
2408N/A years, to give any third party, for a charge no more than your
2408N/A cost of physically performing source distribution, a complete
2408N/A machine-readable copy of the corresponding source code, to be
2408N/A distributed under the terms of Sections 1 and 2 above on a medium
2408N/A customarily used for software interchange; or,
2408N/A c) Accompany it with the information you received as to the offer
2408N/A to distribute corresponding source code. (This alternative is
2408N/A allowed only for noncommercial distribution and only if you
2408N/A received the program in object code or executable form with such
2408N/A an offer, in accord with Subsection b above.)
2408N/AThe source code for a work means the preferred form of the work for
2408N/Amaking modifications to it. For an executable work, complete source
2408N/Acode means all the source code for all modules it contains, plus any
2408N/Aassociated interface definition files, plus the scripts used to
2408N/Acontrol compilation and installation of the executable. However, as a
2408N/Aspecial exception, the source code distributed need not include
2408N/Aanything that is normally distributed (in either source or binary
2408N/Aform) with the major components (compiler, kernel, and so on) of the
2408N/Aoperating system on which the executable runs, unless that component
2408N/Aitself accompanies the executable.
2408N/AIf distribution of executable or object code is made by offering
2408N/Aaccess to copy from a designated place, then offering equivalent
2408N/Aaccess to copy the source code from the same place counts as
2408N/Adistribution of the source code, even though third parties are not
2408N/Acompelled to copy the source along with the object code.
2408N/A 4. You may not copy, modify, sublicense, or distribute the Program
2408N/Aexcept as expressly provided under this License. Any attempt
2408N/Aotherwise to copy, modify, sublicense or distribute the Program is
2408N/Avoid, and will automatically terminate your rights under this License.
2408N/AHowever, parties who have received copies, or rights, from you under
2408N/Athis License will not have their licenses terminated so long as such
2408N/Aparties remain in full compliance.
2408N/A 5. You are not required to accept this License, since you have not
2408N/Asigned it. However, nothing else grants you permission to modify or
2408N/Adistribute the Program or its derivative works. These actions are
2408N/Aprohibited by law if you do not accept this License. Therefore, by
2408N/Amodifying or distributing the Program (or any work based on the
2408N/AProgram), you indicate your acceptance of this License to do so, and
2408N/Aall its terms and conditions for copying, distributing or modifying
2408N/Athe Program or works based on it.
2408N/A 6. Each time you redistribute the Program (or any work based on the
2408N/AProgram), the recipient automatically receives a license from the
2408N/Aoriginal licensor to copy, distribute or modify the Program subject to
2408N/Athese terms and conditions. You may not impose any further
2408N/Arestrictions on the recipients' exercise of the rights granted herein.
2408N/AYou are not responsible for enforcing compliance by third parties to
2408N/A 7. If, as a consequence of a court judgment or allegation of patent
2408N/Ainfringement or for any other reason (not limited to patent issues),
2408N/Aconditions are imposed on you (whether by court order, agreement or
2408N/Aotherwise) that contradict the conditions of this License, they do not
2408N/Aexcuse you from the conditions of this License. If you cannot
2408N/Adistribute so as to satisfy simultaneously your obligations under this
2408N/ALicense and any other pertinent obligations, then as a consequence you
2408N/Amay not distribute the Program at all. For example, if a patent
2408N/Alicense would not permit royalty-free redistribution of the Program by
2408N/Aall those who receive copies directly or indirectly through you, then
2408N/Athe only way you could satisfy both it and this License would be to
2408N/Arefrain entirely from distribution of the Program.
2408N/AIf any portion of this section is held invalid or unenforceable under
2408N/Aany particular circumstance, the balance of the section is intended to
2408N/Aapply and the section as a whole is intended to apply in other
2408N/AIt is not the purpose of this section to induce you to infringe any
2408N/Apatents or other property right claims or to contest validity of any
2408N/Asuch claims; this section has the sole purpose of protecting the
2408N/Aintegrity of the free software distribution system, which is
2408N/Aimplemented by public license practices. Many people have made
2408N/Agenerous contributions to the wide range of software distributed
2408N/Athrough that system in reliance on consistent application of that
2408N/Ato distribute software through any other system and a licensee cannot
2408N/AThis section is intended to make thoroughly clear what is believed to
2408N/Abe a consequence of the rest of this License.
2408N/A 8. If the distribution
and/or use of the Program is restricted in
2408N/Acertain countries either by patents or by copyrighted interfaces, the
2408N/Aoriginal copyright holder who places the Program under this License
2408N/Amay add an explicit geographical distribution limitation excluding
2408N/Athose countries, so that distribution is permitted only in or among
2408N/Acountries not thus excluded. In such case, this License incorporates
2408N/Athe limitation as if written in the body of this License.
2408N/A 9. The Free Software Foundation may publish revised
and/or new versions
2408N/Aof the General Public License from time to time. Such new versions will
2408N/Abe similar in spirit to the present version, but may differ in detail to
2408N/Aaddress new problems or concerns.
2408N/AEach version is given a distinguishing version number. If the Program
2408N/Aspecifies a version number of this License which applies to it and "any
2408N/Alater version", you have the option of following the terms and conditions
2408N/Aeither of that version or of any later version published by the Free
2408N/ASoftware Foundation. If the Program does not specify a version number of
2408N/Athis License, you may choose any version ever published by the Free Software
2408N/A 10. If you wish to incorporate parts of the Program into other free
2408N/Aprograms whose distribution conditions are different, write to the author
2408N/Ato ask for permission. For software which is copyrighted by the Free
2408N/ASoftware Foundation, write to the Free Software Foundation; we sometimes
2408N/Amake exceptions for this. Our decision will be guided by the two goals
2408N/Aof preserving the free status of all derivatives of our free software and
2408N/Aof promoting the sharing and reuse of software generally.
2408N/A 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
2408N/AFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
2408N/AOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES
2408N/APROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
2408N/AOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
2408N/AMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
2408N/ATO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
2408N/APROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
2408N/A 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
2408N/AWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR 2408N/AREDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
2408N/AINCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
2408N/AOUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
2408N/ATO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
2408N/AYOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
2408N/APROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
2408N/APOSSIBILITY OF SUCH DAMAGES.
2408N/A END OF TERMS AND CONDITIONS
2408N/A Appendix: How to Apply These Terms to Your New Programs
2408N/A If you develop a new program, and you want it to be of the greatest
2408N/Apossible use to the public, the best way to achieve this is to make it
2408N/Afree software which everyone can redistribute and change under these terms.
2408N/A To do so, attach the following notices to the program. It is safest
2408N/Ato attach them to the start of each source file to most effectively
2408N/Aconvey the exclusion of warranty; and each file should have at least
2408N/Athe "copyright" line and a pointer to where the full notice is found.
2408N/A <one line to give the program's name and a brief idea of what it does.>
2408N/A Copyright (C) 19yy <name of author>
2408N/A This program is free software; you can redistribute it
and/or modify
2408N/A it under the terms of the GNU General Public License as published by
2408N/A the Free Software Foundation; either version 2 of the License, or
2408N/A (at your option) any later version.
2408N/A This program is distributed in the hope that it will be useful,
2408N/A but WITHOUT ANY WARRANTY; without even the implied warranty of
2408N/A MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
2408N/A GNU General Public License for more details.
2408N/A You should have received a copy of the GNU General Public License
2408N/A along with this program; if not, write to the Free Software
2408N/A Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
2408N/AAlso add information on how to contact you by electronic and paper mail.
2408N/AIf the program is interactive, make it output a short notice like this
2408N/Awhen it starts in an interactive mode:
2408N/A Gnomovision version 69, Copyright (C) 19yy name of author
2408N/A Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
2408N/A This is free software, and you are welcome to redistribute it
2408N/A under certain conditions; type `show c' for details.
2408N/AThe hypothetical commands `show w' and `show c' should show the appropriate
2408N/Aparts of the General Public License. Of course, the commands you use may
2408N/Abe called something other than `show w' and `show c'; they could even be
2408N/Amouse-clicks or menu items--whatever suits your program.
2408N/AYou should also get your employer (if you work as a programmer) or your
2408N/Aschool, if any, to sign a "copyright disclaimer" for the program, if
2408N/Anecessary. Here is a sample; alter the names:
2408N/A Yoyodyne, Inc., hereby disclaims all copyright interest in the program
2408N/A `Gnomovision' (which makes passes at compilers) written by James Hacker.
2408N/A <signature of Ty Coon>, 1 April 1989
2408N/AThis General Public License does not permit incorporating your program into
2408N/Aproprietary programs. If your program is a subroutine library, you may
2408N/Aconsider it more useful to permit linking proprietary applications with the
2408N/Alibrary. If this is what you want to do, use the GNU Library General
2408N/APublic License instead of this License.
