570 675 Mass Ave, Cambridge, MA 02139, USA
571 Everyone is permitted to copy and distribute verbatim copies
572 of this license document, but changing it is not allowed.
576 The licenses for most software are designed to take away your
577 freedom to share and change it. By contrast, the GNU General Public
578 License is intended to guarantee your freedom to share and change free
579 software--to make sure the software is free for all its users. This
580 General Public License applies to most of the Free Software
581 Foundation's software and to any other program whose authors commit to
582 using it. (Some other Free Software Foundation software is covered by
583 the GNU Library General Public License instead.) You can apply it to
586 When we speak of free software, we are referring to freedom, not
587 price. Our General Public Licenses are designed to make sure that you
588 have the freedom to distribute copies of free software (and charge for
589 this service if you wish), that you receive source code or can get it
590 if you want it, that you can change the software or use pieces of it
591 in new free programs; and that you know you can do these things.
593 To protect your rights, we need to make restrictions that forbid
594 anyone to deny you these rights or to ask you to surrender the rights.
595 These restrictions translate to certain responsibilities for you if you
596 distribute copies of the software, or if you modify it.
598 For example, if you distribute copies of such a program, whether
599 gratis or for a fee, you must give the recipients all the rights that
600 you have. You must make sure that they, too, receive or can get the
601 source code. And you must show them these terms so they know their
604 We protect your rights with two steps: (1) copyright the software, and
605 (2) offer you this license which gives you legal permission to copy,
606 distribute and/or modify the software.
608 Also, for each author's protection and ours, we want to make certain
609 that everyone understands that there is no warranty for this free
610 software. If the software is modified by someone else and passed on, we
611 want its recipients to know that what they have is not the original, so
612 that any problems introduced by others will not reflect on the original
613 authors' reputations.
615 Finally, any free program is threatened constantly by software
616 patents. We wish to avoid the danger that redistributors of a free
617 program will individually obtain patent licenses, in effect making the
618 program proprietary. To prevent this, we have made it clear that any
619 patent must be licensed for everyone's free use or not licensed at all.
621 The precise terms and conditions for copying, distribution and
625 GNU GENERAL PUBLIC LICENSE
626 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
628 0. This License applies to any program or other work which contains
629 a notice placed by the copyright holder saying it may be distributed
630 under the terms of this General Public License. The "Program", below,
631 refers to any such program or work, and a "work based on the Program"
632 means either the Program or any derivative work under copyright law:
633 that is to say, a work containing the Program or a portion of it,
634 either verbatim or with modifications and/or translated into another
635 language. (Hereinafter, translation is included without limitation in
636 the term "modification".) Each licensee is addressed as "you".
638 Activities other than copying, distribution and modification are not
639 covered by this License; they are outside its scope. The act of
640 running the Program is not restricted, and the output from the Program
641 is covered only if its contents constitute a work based on the
642 Program (independent of having been made by running the Program).
643 Whether that is true depends on what the Program does.
645 1. You may copy and distribute verbatim copies of the Program's
646 source code as you receive it, in any medium, provided that you
647 conspicuously and appropriately publish on each copy an appropriate
648 copyright notice and disclaimer of warranty; keep intact all the
649 notices that refer to this License and to the absence of any warranty;
650 and give any other recipients of the Program a copy of this License
651 along with the Program.
653 You may charge a fee for the physical act of transferring a copy, and
654 you may at your option offer warranty protection in exchange for a fee.
656 2. You may modify your copy or copies of the Program or any portion
657 of it, thus forming a work based on the Program, and copy and
658 distribute such modifications or work under the terms of Section 1
659 above, provided that you also meet all of these conditions:
661 a) You must cause the modified files to carry prominent notices
662 stating that you changed the files and the date of any change.
664 b) You must cause any work that you distribute or publish, that in
665 whole or in part contains or is derived from the Program or any
666 part thereof, to be licensed as a whole at no charge to all third
667 parties under the terms of this License.
669 c) If the modified program normally reads commands interactively
670 when run, you must cause it, when started running for such
671 interactive use in the most ordinary way, to print or display an
672 announcement including an appropriate copyright notice and a
673 notice that there is no warranty (or else, saying that you provide
674 a warranty) and that users may redistribute the program under
675 these conditions, and telling the user how to view a copy of this
676 License. (Exception: if the Program itself is interactive but
677 does not normally print such an announcement, your work based on
678 the Program is not required to print an announcement.)
681 These requirements apply to the modified work as a whole. If
682 identifiable sections of that work are not derived from the Program,
683 and can be reasonably considered independent and separate works in
684 themselves, then this License, and its terms, do not apply to those
685 sections when you distribute them as separate works. But when you
686 distribute the same sections as part of a whole which is a work based
687 on the Program, the distribution of the whole must be on the terms of
688 this License, whose permissions for other licensees extend to the
689 entire whole, and thus to each and every part regardless of who wrote it.
691 Thus, it is not the intent of this section to claim rights or contest
692 your rights to work written entirely by you; rather, the intent is to
693 exercise the right to control the distribution of derivative or
694 collective works based on the Program.
696 In addition, mere aggregation of another work not based on the Program
697 with the Program (or with a work based on the Program) on a volume of
698 a storage or distribution medium does not bring the other work under
699 the scope of this License.
701 3. You may copy and distribute the Program (or a work based on it,
702 under Section 2) in object code or executable form under the terms of
703 Sections 1 and 2 above provided that you also do one of the following:
705 a) Accompany it with the complete corresponding machine-readable
706 source code, which must be distributed under the terms of Sections
707 1 and 2 above on a medium customarily used for software interchange; or,
709 b) Accompany it with a written offer, valid for at least three
710 years, to give any third party, for a charge no more than your
711 cost of physically performing source distribution, a complete
712 machine-readable copy of the corresponding source code, to be
713 distributed under the terms of Sections 1 and 2 above on a medium
714 customarily used for software interchange; or,
716 c) Accompany it with the information you received as to the offer
717 to distribute corresponding source code. (This alternative is
718 allowed only for noncommercial distribution and only if you
719 received the program in object code or executable form with such
720 an offer, in accord with Subsection b above.)
722 The source code for a work means the preferred form of the work for
723 making modifications to it. For an executable work, complete source
724 code means all the source code for all modules it contains, plus any
725 associated interface definition files, plus the scripts used to
726 control compilation and installation of the executable. However, as a
727 special exception, the source code distributed need not include
728 anything that is normally distributed (in either source or binary
729 form) with the major components (compiler, kernel, and so on) of the
730 operating system on which the executable runs, unless that component
731 itself accompanies the executable.
733 If distribution of executable or object code is made by offering
734 access to copy from a designated place, then offering equivalent
735 access to copy the source code from the same place counts as
736 distribution of the source code, even though third parties are not
737 compelled to copy the source along with the object code.
740 4. You may not copy, modify, sublicense, or distribute the Program
741 except as expressly provided under this License. Any attempt
742 otherwise to copy, modify, sublicense or distribute the Program is
743 void, and will automatically terminate your rights under this License.
744 However, parties who have received copies, or rights, from you under
745 this License will not have their licenses terminated so long as such
746 parties remain in full compliance.
748 5. You are not required to accept this License, since you have not
749 signed it. However, nothing else grants you permission to modify or
750 distribute the Program or its derivative works. These actions are
751 prohibited by law if you do not accept this License. Therefore, by
752 modifying or distributing the Program (or any work based on the
753 Program), you indicate your acceptance of this License to do so, and
754 all its terms and conditions for copying, distributing or modifying
755 the Program or works based on it.
757 6. Each time you redistribute the Program (or any work based on the
758 Program), the recipient automatically receives a license from the
759 original licensor to copy, distribute or modify the Program subject to
760 these terms and conditions. You may not impose any further
761 restrictions on the recipients' exercise of the rights granted herein.
762 You are not responsible for enforcing compliance by third parties to
765 7. If, as a consequence of a court judgment or allegation of patent
766 infringement or for any other reason (not limited to patent issues),
767 conditions are imposed on you (whether by court order, agreement or
768 otherwise) that contradict the conditions of this License, they do not
769 excuse you from the conditions of this License. If you cannot
770 distribute so as to satisfy simultaneously your obligations under this
771 License and any other pertinent obligations, then as a consequence you
772 may not distribute the Program at all. For example, if a patent
773 license would not permit royalty-free redistribution of the Program by
774 all those who receive copies directly or indirectly through you, then
775 the only way you could satisfy both it and this License would be to
776 refrain entirely from distribution of the Program.
778 If any portion of this section is held invalid or unenforceable under
779 any particular circumstance, the balance of the section is intended to
780 apply and the section as a whole is intended to apply in other
783 It is not the purpose of this section to induce you to infringe any
784 patents or other property right claims or to contest validity of any
785 such claims; this section has the sole purpose of protecting the
786 integrity of the free software distribution system, which is
787 implemented by public license practices. Many people have made
788 generous contributions to the wide range of software distributed
789 through that system in reliance on consistent application of that
790 system; it is up to the author/donor to decide if he or she is willing
791 to distribute software through any other system and a licensee cannot
794 This section is intended to make thoroughly clear what is believed to
795 be a consequence of the rest of this License.
798 8. If the distribution and/or use of the Program is restricted in
799 certain countries either by patents or by copyrighted interfaces, the
800 original copyright holder who places the Program under this License
801 may add an explicit geographical distribution limitation excluding
802 those countries, so that distribution is permitted only in or among
803 countries not thus excluded. In such case, this License incorporates
804 the limitation as if written in the body of this License.
806 9. The Free Software Foundation may publish revised and/or new versions
807 of the General Public License from time to time. Such new versions will
808 be similar in spirit to the present version, but may differ in detail to
809 address new problems or concerns.
811 Each version is given a distinguishing version number. If the Program
812 specifies a version number of this License which applies to it and "any
813 later version", you have the option of following the terms and conditions
814 either of that version or of any later version published by the Free
815 Software Foundation. If the Program does not specify a version number of
816 this License, you may choose any version ever published by the Free Software
819 10. If you wish to incorporate parts of the Program into other free
820 programs whose distribution conditions are different, write to the author
821 to ask for permission. For software which is copyrighted by the Free
822 Software Foundation, write to the Free Software Foundation; we sometimes
823 make exceptions for this. Our decision will be guided by the two goals
824 of preserving the free status of all derivatives of our free software and
825 of promoting the sharing and reuse of software generally.
829 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
830 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
831 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
832 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
833 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
834 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
835 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
836 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
837 REPAIR OR CORRECTION.
839 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
840 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
841 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
842 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
843 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
844 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
845 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
846 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
847 POSSIBILITY OF SUCH DAMAGES.
