5325N/A Everyone is permitted to copy and distribute verbatim copies
5325N/A of this license document, but changing it is not allowed.
5325N/A The licenses for most software are designed to take away your
5325N/Afreedom to share and change it. By contrast, the GNU General Public
5325N/ALicense is intended to guarantee your freedom to share and change free
5325N/Asoftware--to make sure the software is free for all its users. This
5325N/AGeneral Public License applies to most of the Free Software
5325N/AFoundation's software and to any other program whose authors commit to
5325N/Ausing it. (Some other Free Software Foundation software is covered by
5325N/Athe GNU Library General Public License instead.) You can apply it to
5325N/A When we speak of free software, we are referring to freedom, not
5325N/Aprice. Our General Public Licenses are designed to make sure that you
5325N/Ahave the freedom to distribute copies of free software (and charge for
5325N/Athis service if you wish), that you receive source code or can get it
5325N/Aif you want it, that you can change the software or use pieces of it
5325N/Ain new free programs; and that you know you can do these things.
5325N/A To protect your rights, we need to make restrictions that forbid
5325N/Aanyone to deny you these rights or to ask you to surrender the rights.
5325N/AThese restrictions translate to certain responsibilities for you if you
5325N/Adistribute copies of the software, or if you modify it.
5325N/A For example, if you distribute copies of such a program, whether
5325N/Agratis or for a fee, you must give the recipients all the rights that
5325N/Ayou have. You must make sure that they, too, receive or can get the
5325N/Asource code. And you must show them these terms so they know their
5325N/A We protect your rights with two steps: (1) copyright the software, and
5325N/A(2) offer you this license which gives you legal permission to copy,
5325N/A Also, for each author's protection and ours, we want to make certain
5325N/Athat everyone understands that there is no warranty for this free
5325N/Asoftware. If the software is modified by someone else and passed on, we
5325N/Awant its recipients to know that what they have is not the original, so
5325N/Athat any problems introduced by others will not reflect on the original
5325N/A Finally, any free program is threatened constantly by software
5325N/Apatents. We wish to avoid the danger that redistributors of a free
5325N/Aprogram will individually obtain patent licenses, in effect making the
5325N/Aprogram proprietary. To prevent this, we have made it clear that any
5325N/Apatent must be licensed for everyone's free use or not licensed at all.
5325N/A The precise terms and conditions for copying, distribution and
5325N/A TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
5325N/A 0. This License applies to any program or other work which contains
5325N/Aa notice placed by the copyright holder saying it may be distributed
5325N/Aunder the terms of this General Public License. The "Program", below,
5325N/Arefers to any such program or work, and a "work based on the Program"
5325N/Ameans either the Program or any derivative work under copyright law:
5325N/Athat is to say, a work containing the Program or a portion of it,
5325N/Aeither verbatim or with modifications
and/or translated into another
5325N/Alanguage. (Hereinafter, translation is included without limitation in
5325N/Athe term "modification".) Each licensee is addressed as "you".
5325N/AActivities other than copying, distribution and modification are not
5325N/Acovered by this License; they are outside its scope. The act of
5325N/Arunning the Program is not restricted, and the output from the Program
5325N/Ais covered only if its contents constitute a work based on the
5325N/AProgram (independent of having been made by running the Program).
5325N/AWhether that is true depends on what the Program does.
5325N/A 1. You may copy and distribute verbatim copies of the Program's
5325N/Asource code as you receive it, in any medium, provided that you
5325N/Aconspicuously and appropriately publish on each copy an appropriate
5325N/Acopyright notice and disclaimer of warranty; keep intact all the
5325N/Anotices that refer to this License and to the absence of any warranty;
5325N/Aand give any other recipients of the Program a copy of this License
5325N/AYou may charge a fee for the physical act of transferring a copy, and
5325N/Ayou may at your option offer warranty protection in exchange for a fee.
5325N/A 2. You may modify your copy or copies of the Program or any portion
5325N/Aof it, thus forming a work based on the Program, and copy and
5325N/Adistribute such modifications or work under the terms of Section 1
5325N/Aabove, provided that you also meet all of these conditions:
5325N/A a) You must cause the modified files to carry prominent notices
5325N/A stating that you changed the files and the date of any change.
5325N/A b) You must cause any work that you distribute or publish, that in
5325N/A whole or in part contains or is derived from the Program or any
5325N/A part thereof, to be licensed as a whole at no charge to all third
5325N/A parties under the terms of this License.
5325N/A c) If the modified program normally reads commands interactively
5325N/A when run, you must cause it, when started running for such
5325N/A interactive use in the most ordinary way, to print or display an
5325N/A announcement including an appropriate copyright notice and a
5325N/A notice that there is no warranty (or else, saying that you provide
5325N/A a warranty) and that users may redistribute the program under
5325N/A these conditions, and telling the user how to view a copy of this
5325N/A License. (Exception: if the Program itself is interactive but
5325N/A does not normally print such an announcement, your work based on
5325N/A the Program is not required to print an announcement.)
5325N/AThese requirements apply to the modified work as a whole. If
5325N/Aidentifiable sections of that work are not derived from the Program,
5325N/Aand can be reasonably considered independent and separate works in
5325N/Athemselves, then this License, and its terms, do not apply to those
5325N/Asections when you distribute them as separate works. But when you
5325N/Adistribute the same sections as part of a whole which is a work based
5325N/Aon the Program, the distribution of the whole must be on the terms of
5325N/Athis License, whose permissions for other licensees extend to the
5325N/Aentire whole, and thus to each and every part regardless of who wrote it.
5325N/AThus, it is not the intent of this section to claim rights or contest
5325N/Ayour rights to work written entirely by you; rather, the intent is to
5325N/Aexercise the right to control the distribution of derivative or
5325N/Acollective works based on the Program.
5325N/AIn addition, mere aggregation of another work not based on the Program
5325N/Awith the Program (or with a work based on the Program) on a volume of
5325N/Aa storage or distribution medium does not bring the other work under
5325N/A 3. You may copy and distribute the Program (or a work based on it,
5325N/Aunder Section 2) in object code or executable form under the terms of
5325N/ASections 1 and 2 above provided that you also do one of the following:
5325N/A a) Accompany it with the complete corresponding machine-readable
5325N/A source code, which must be distributed under the terms of Sections
5325N/A 1 and 2 above on a medium customarily used for software interchange; or,
5325N/A b) Accompany it with a written offer, valid for at least three
5325N/A years, to give any third party, for a charge no more than your
5325N/A cost of physically performing source distribution, a complete
5325N/A machine-readable copy of the corresponding source code, to be
5325N/A distributed under the terms of Sections 1 and 2 above on a medium
5325N/A customarily used for software interchange; or,
5325N/A c) Accompany it with the information you received as to the offer
5325N/A to distribute corresponding source code. (This alternative is
5325N/A allowed only for noncommercial distribution and only if you
5325N/A received the program in object code or executable form with such
5325N/A an offer, in accord with Subsection b above.)
5325N/AThe source code for a work means the preferred form of the work for
5325N/Amaking modifications to it. For an executable work, complete source
5325N/Acode means all the source code for all modules it contains, plus any
5325N/Aassociated interface definition files, plus the scripts used to
5325N/Acontrol compilation and installation of the executable. However, as a
5325N/Aspecial exception, the source code distributed need not include
5325N/Aanything that is normally distributed (in either source or binary
5325N/Aform) with the major components (compiler, kernel, and so on) of the
5325N/Aoperating system on which the executable runs, unless that component
5325N/Aitself accompanies the executable.
5325N/AIf distribution of executable or object code is made by offering
5325N/Aaccess to copy from a designated place, then offering equivalent
5325N/Aaccess to copy the source code from the same place counts as
5325N/Adistribution of the source code, even though third parties are not
5325N/Acompelled to copy the source along with the object code.
5325N/A 4. You may not copy, modify, sublicense, or distribute the Program
5325N/Aexcept as expressly provided under this License. Any attempt
5325N/Aotherwise to copy, modify, sublicense or distribute the Program is
5325N/Avoid, and will automatically terminate your rights under this License.
5325N/AHowever, parties who have received copies, or rights, from you under
5325N/Athis License will not have their licenses terminated so long as such
5325N/Aparties remain in full compliance.
5325N/A 5. You are not required to accept this License, since you have not
5325N/Asigned it. However, nothing else grants you permission to modify or
5325N/Adistribute the Program or its derivative works. These actions are
5325N/Aprohibited by law if you do not accept this License. Therefore, by
5325N/Amodifying or distributing the Program (or any work based on the
5325N/AProgram), you indicate your acceptance of this License to do so, and
5325N/Aall its terms and conditions for copying, distributing or modifying
5325N/Athe Program or works based on it.
5325N/A 6. Each time you redistribute the Program (or any work based on the
5325N/AProgram), the recipient automatically receives a license from the
5325N/Aoriginal licensor to copy, distribute or modify the Program subject to
5325N/Athese terms and conditions. You may not impose any further
5325N/Arestrictions on the recipients' exercise of the rights granted herein.
5325N/AYou are not responsible for enforcing compliance by third parties to
5325N/A 7. If, as a consequence of a court judgment or allegation of patent
5325N/Ainfringement or for any other reason (not limited to patent issues),
5325N/Aconditions are imposed on you (whether by court order, agreement or
5325N/Aotherwise) that contradict the conditions of this License, they do not
5325N/Aexcuse you from the conditions of this License. If you cannot
5325N/Adistribute so as to satisfy simultaneously your obligations under this
5325N/ALicense and any other pertinent obligations, then as a consequence you
5325N/Amay not distribute the Program at all. For example, if a patent
5325N/Alicense would not permit royalty-free redistribution of the Program by
5325N/Aall those who receive copies directly or indirectly through you, then
5325N/Athe only way you could satisfy both it and this License would be to
5325N/Arefrain entirely from distribution of the Program.
5325N/AIf any portion of this section is held invalid or unenforceable under
5325N/Aany particular circumstance, the balance of the section is intended to
5325N/Aapply and the section as a whole is intended to apply in other
5325N/AIt is not the purpose of this section to induce you to infringe any
5325N/Apatents or other property right claims or to contest validity of any
5325N/Asuch claims; this section has the sole purpose of protecting the
5325N/Aintegrity of the free software distribution system, which is
5325N/Aimplemented by public license practices. Many people have made
5325N/Agenerous contributions to the wide range of software distributed
5325N/Athrough that system in reliance on consistent application of that
5325N/Ato distribute software through any other system and a licensee cannot
5325N/AThis section is intended to make thoroughly clear what is believed to
5325N/Abe a consequence of the rest of this License.
5325N/A 8. If the distribution
and/or use of the Program is restricted in
5325N/Acertain countries either by patents or by copyrighted interfaces, the
5325N/Aoriginal copyright holder who places the Program under this License
5325N/Amay add an explicit geographical distribution limitation excluding
5325N/Athose countries, so that distribution is permitted only in or among
5325N/Acountries not thus excluded. In such case, this License incorporates
5325N/Athe limitation as if written in the body of this License.
5325N/A 9. The Free Software Foundation may publish revised
and/or new versions
5325N/Aof the General Public License from time to time. Such new versions will
5325N/Abe similar in spirit to the present version, but may differ in detail to
5325N/Aaddress new problems or concerns.
5325N/AEach version is given a distinguishing version number. If the Program
5325N/Aspecifies a version number of this License which applies to it and "any
5325N/Alater version", you have the option of following the terms and conditions
5325N/Aeither of that version or of any later version published by the Free
5325N/ASoftware Foundation. If the Program does not specify a version number of
5325N/Athis License, you may choose any version ever published by the Free Software
5325N/A 10. If you wish to incorporate parts of the Program into other free
5325N/Aprograms whose distribution conditions are different, write to the author
5325N/Ato ask for permission. For software which is copyrighted by the Free
5325N/ASoftware Foundation, write to the Free Software Foundation; we sometimes
5325N/Amake exceptions for this. Our decision will be guided by the two goals
5325N/Aof preserving the free status of all derivatives of our free software and
5325N/Aof promoting the sharing and reuse of software generally.
5325N/A 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
5325N/AFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
5325N/AOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES
5325N/APROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
5325N/AOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
5325N/AMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
5325N/ATO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
5325N/APROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
5325N/A 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
5325N/AWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR 5325N/AREDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
5325N/AINCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
5325N/AOUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
5325N/ATO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
5325N/AYOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
5325N/APROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
5325N/APOSSIBILITY OF SUCH DAMAGES.
5325N/A END OF TERMS AND CONDITIONS
5325N/A How to Apply These Terms to Your New Programs
5325N/A If you develop a new program, and you want it to be of the greatest
5325N/Apossible use to the public, the best way to achieve this is to make it
5325N/Afree software which everyone can redistribute and change under these terms.
5325N/A To do so, attach the following notices to the program. It is safest
5325N/Ato attach them to the start of each source file to most effectively
5325N/Aconvey the exclusion of warranty; and each file should have at least
5325N/Athe "copyright" line and a pointer to where the full notice is found.
5325N/A <one line to give the program's name and a brief idea of what it does.>
5325N/A Copyright (C) <year> <name of author>
5325N/A This program is free software; you can redistribute it
and/or modify
5325N/A it under the terms of the GNU General Public License as published by
5325N/A the Free Software Foundation; either version 2 of the License, or
5325N/A (at your option) any later version.
5325N/A This program is distributed in the hope that it will be useful,
5325N/A but WITHOUT ANY WARRANTY; without even the implied warranty of
5325N/A MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
5325N/A GNU General Public License for more details.
5325N/A You should have received a copy of the GNU General Public License
5325N/A along with this program; if not, write to the Free Software
5325N/A Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
5325N/AAlso add information on how to contact you by electronic and paper mail.
5325N/AIf the program is interactive, make it output a short notice like this
5325N/Awhen it starts in an interactive mode:
5325N/A Gnomovision version 69, Copyright (C) year name of author
5325N/A Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
5325N/A This is free software, and you are welcome to redistribute it
5325N/A under certain conditions; type `show c' for details.
5325N/AThe hypothetical commands `show w' and `show c' should show the appropriate
5325N/Aparts of the General Public License. Of course, the commands you use may
5325N/Abe called something other than `show w' and `show c'; they could even be
5325N/Amouse-clicks or menu items--whatever suits your program.
5325N/AYou should also get your employer (if you work as a programmer) or your
5325N/Aschool, if any, to sign a "copyright disclaimer" for the program, if
5325N/Anecessary. Here is a sample; alter the names:
5325N/A Yoyodyne, Inc., hereby disclaims all copyright interest in the program
5325N/A `Gnomovision' (which makes passes at compilers) written by James Hacker.
5325N/A <signature of Ty Coon>, 1 April 1989
5325N/AThis General Public License does not permit incorporating your program into
5325N/Aproprietary programs. If your program is a subroutine library, you may
5325N/Aconsider it more useful to permit linking proprietary applications with the
5325N/Alibrary. If this is what you want to do, use the GNU Library General
5325N/APublic License instead of this License.
