|---|
| 580 | | Copyright (C) 1989, 1991 Free Software Foundation, Inc.\ |
|---|
| 581 | | 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA\ |
|---|
| 582 | | Everyone is permitted to copy and distribute verbatim copies\ |
|---|
| 583 | | of this license document, but changing it is not allowed.\ |
|---|
| 584 | | \ |
|---|
| 585 | | Preamble\ |
|---|
| 586 | | \ |
|---|
| 587 | | The licenses for most software are designed to take away your\ |
|---|
| 588 | | freedom to share and change it. By contrast, the GNU General Public\ |
|---|
| 589 | | License is intended to guarantee your freedom to share and change free\ |
|---|
| 590 | | software--to make sure the software is free for all its users. This\ |
|---|
| 591 | | General Public License applies to most of the Free Software\ |
|---|
| 592 | | Foundation's software and to any other program whose authors commit to\ |
|---|
| 593 | | using it. (Some other Free Software Foundation software is covered by\ |
|---|
| 594 | | the GNU Library General Public License instead.) You can apply it to\ |
|---|
| 595 | | your programs, too.\ |
|---|
| 596 | | \ |
|---|
| 597 | | When we speak of free software, we are referring to freedom, not\ |
|---|
| 598 | | price. Our General Public Licenses are designed to make sure that you\ |
|---|
| 599 | | have the freedom to distribute copies of free software (and charge for\ |
|---|
| 600 | | this service if you wish), that you receive source code or can get it\ |
|---|
| 601 | | if you want it, that you can change the software or use pieces of it\ |
|---|
| 602 | | in new free programs; and that you know you can do these things.\ |
|---|
| 603 | | \ |
|---|
| 604 | | To protect your rights, we need to make restrictions that forbid\ |
|---|
| 605 | | anyone to deny you these rights or to ask you to surrender the rights.\ |
|---|
| 606 | | These restrictions translate to certain responsibilities for you if you\ |
|---|
| 607 | | distribute copies of the software, or if you modify it.\ |
|---|
| 608 | | \ |
|---|
| 609 | | For example, if you distribute copies of such a program, whether\ |
|---|
| 610 | | gratis or for a fee, you must give the recipients all the rights that\ |
|---|
| 611 | | you have. You must make sure that they, too, receive or can get the\ |
|---|
| 612 | | source code. And you must show them these terms so they know their\ |
|---|
| 613 | | rights.\ |
|---|
| 614 | | \ |
|---|
| 615 | | We protect your rights with two steps: (1) copyright the software, and\ |
|---|
| 616 | | (2) offer you this license which gives you legal permission to copy,\ |
|---|
| 617 | | distribute and/or modify the software.\ |
|---|
| 618 | | \ |
|---|
| 619 | | Also, for each author's protection and ours, we want to make certain\ |
|---|
| 620 | | that everyone understands that there is no warranty for this free\ |
|---|
| 621 | | software. If the software is modified by someone else and passed on, we\ |
|---|
| 622 | | want its recipients to know that what they have is not the original, so\ |
|---|
| 623 | | that any problems introduced by others will not reflect on the original\ |
|---|
| 624 | | authors' reputations.\ |
|---|
| 625 | | \ |
|---|
| 626 | | Finally, any free program is threatened constantly by software\ |
|---|
| 627 | | patents. We wish to avoid the danger that redistributors of a free\ |
|---|
| 628 | | program will individually obtain patent licenses, in effect making the\ |
|---|
| 629 | | program proprietary. To prevent this, we have made it clear that any\ |
|---|
| 630 | | patent must be licensed for everyone's free use or not licensed at all.\ |
|---|
| 631 | | \ |
|---|
| 632 | | The precise terms and conditions for copying, distribution and\ |
|---|
| 633 | | modification follow.\ |
|---|
| 634 | | \page \ |
|---|
| 635 | | GNU GENERAL PUBLIC LICENSE\ |
|---|
| 636 | | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\ |
|---|
| 637 | | \ |
|---|
| 638 | | 0. This License applies to any program or other work which contains\ |
|---|
| 639 | | a notice placed by the copyright holder saying it may be distributed\ |
|---|
| 640 | | under the terms of this General Public License. The "Program", below,\ |
|---|
| 641 | | refers to any such program or work, and a "work based on the Program"\ |
|---|
| 642 | | means either the Program or any derivative work under copyright law:\ |
|---|
| 643 | | that is to say, a work containing the Program or a portion of it,\ |
|---|
| 644 | | either verbatim or with modifications and/or translated into another\ |
|---|
| 645 | | language. (Hereinafter, translation is included without limitation in\ |
|---|
| 646 | | the term "modification".) Each licensee is addressed as "you".\ |
|---|
| 647 | | \ |
|---|
| 648 | | Activities other than copying, distribution and modification are not\ |
|---|
| 649 | | covered by this License; they are outside its scope. The act of\ |
|---|
| 650 | | running the Program is not restricted, and the output from the Program\ |
|---|
| 651 | | is covered only if its contents constitute a work based on the\ |
|---|
| 652 | | Program (independent of having been made by running the Program).\ |
|---|
| 653 | | Whether that is true depends on what the Program does.\ |
|---|
| 654 | | \ |
|---|
| 655 | | 1. You may copy and distribute verbatim copies of the Program's\ |
|---|
| 656 | | source code as you receive it, in any medium, provided that you\ |
|---|
| 657 | | conspicuously and appropriately publish on each copy an appropriate\ |
|---|
| 658 | | copyright notice and disclaimer of warranty; keep intact all the\ |
|---|
| 659 | | notices that refer to this License and to the absence of any warranty;\ |
|---|
| 660 | | and give any other recipients of the Program a copy of this License\ |
|---|
| 661 | | along with the Program.\ |
|---|
| 662 | | \ |
|---|
| 663 | | You may charge a fee for the physical act of transferring a copy, and\ |
|---|
| 664 | | you may at your option offer warranty protection in exchange for a fee.\ |
|---|
| 665 | | \ |
|---|
| 666 | | 2. You may modify your copy or copies of the Program or any portion\ |
|---|
| 667 | | of it, thus forming a work based on the Program, and copy and\ |
|---|
| 668 | | distribute such modifications or work under the terms of Section 1\ |
|---|
| 669 | | above, provided that you also meet all of these conditions:\ |
|---|
| 670 | | \ |
|---|
| 671 | | a) You must cause the modified files to carry prominent notices\ |
|---|
| 672 | | stating that you changed the files and the date of any change.\ |
|---|
| 673 | | \ |
|---|
| 674 | | b) You must cause any work that you distribute or publish, that in\ |
|---|
| 675 | | whole or in part contains or is derived from the Program or any\ |
|---|
| 676 | | part thereof, to be licensed as a whole at no charge to all third\ |
|---|
| 677 | | parties under the terms of this License.\ |
|---|
| 678 | | \ |
|---|
| 679 | | c) If the modified program normally reads commands interactively\ |
|---|
| 680 | | when run, you must cause it, when started running for such\ |
|---|
| 681 | | interactive use in the most ordinary way, to print or display an\ |
|---|
| 682 | | announcement including an appropriate copyright notice and a\ |
|---|
| 683 | | notice that there is no warranty (or else, saying that you provide\ |
|---|
| 684 | | a warranty) and that users may redistribute the program under\ |
|---|
| 685 | | these conditions, and telling the user how to view a copy of this\ |
|---|
| 686 | | License. (Exception: if the Program itself is interactive but\ |
|---|
| 687 | | does not normally print such an announcement, your work based on\ |
|---|
| 688 | | the Program is not required to print an announcement.)\ |
|---|
| 689 | | \page \ |
|---|
| 690 | | These requirements apply to the modified work as a whole. If\ |
|---|
| 691 | | identifiable sections of that work are not derived from the Program,\ |
|---|
| 692 | | and can be reasonably considered independent and separate works in\ |
|---|
| 693 | | themselves, then this License, and its terms, do not apply to those\ |
|---|
| 694 | | sections when you distribute them as separate works. But when you\ |
|---|
| 695 | | distribute the same sections as part of a whole which is a work based\ |
|---|
| 696 | | on the Program, the distribution of the whole must be on the terms of\ |
|---|
| 697 | | this License, whose permissions for other licensees extend to the\ |
|---|
| 698 | | entire whole, and thus to each and every part regardless of who wrote it.\ |
|---|
| 699 | | \ |
|---|
| 700 | | Thus, it is not the intent of this section to claim rights or contest\ |
|---|
| 701 | | your rights to work written entirely by you; rather, the intent is to\ |
|---|
| 702 | | exercise the right to control the distribution of derivative or\ |
|---|
| 703 | | collective works based on the Program.\ |
|---|
| 704 | | \ |
|---|
| 705 | | In addition, mere aggregation of another work not based on the Program\ |
|---|
| 706 | | with the Program (or with a work based on the Program) on a volume of\ |
|---|
| 707 | | a storage or distribution medium does not bring the other work under\ |
|---|
| 708 | | the scope of this License.\ |
|---|
| 709 | | \ |
|---|
| 710 | | 3. You may copy and distribute the Program (or a work based on it,\ |
|---|
| 711 | | under Section 2) in object code or executable form under the terms of\ |
|---|
| 712 | | Sections 1 and 2 above provided that you also do one of the following:\ |
|---|
| 713 | | \ |
|---|
| 714 | | a) Accompany it with the complete corresponding machine-readable\ |
|---|
| 715 | | source code, which must be distributed under the terms of Sections\ |
|---|
| 716 | | 1 and 2 above on a medium customarily used for software interchange; or,\ |
|---|
| 717 | | \ |
|---|
| 718 | | b) Accompany it with a written offer, valid for at least three\ |
|---|
| 719 | | years, to give any third party, for a charge no more than your\ |
|---|
| 720 | | cost of physically performing source distribution, a complete\ |
|---|
| 721 | | machine-readable copy of the corresponding source code, to be\ |
|---|
| 722 | | distributed under the terms of Sections 1 and 2 above on a medium\ |
|---|
| 723 | | customarily used for software interchange; or,\ |
|---|
| 724 | | \ |
|---|
| 725 | | c) Accompany it with the information you received as to the offer\ |
|---|
| 726 | | to distribute corresponding source code. (This alternative is\ |
|---|
| 727 | | allowed only for noncommercial distribution and only if you\ |
|---|
| 728 | | received the program in object code or executable form with such\ |
|---|
| 729 | | an offer, in accord with Subsection b above.)\ |
|---|
| 730 | | \ |
|---|
| 731 | | The source code for a work means the preferred form of the work for\ |
|---|
| 732 | | making modifications to it. For an executable work, complete source\ |
|---|
| 733 | | code means all the source code for all modules it contains, plus any\ |
|---|
| 734 | | associated interface definition files, plus the scripts used to\ |
|---|
| 735 | | control compilation and installation of the executable. However, as a\ |
|---|
| 736 | | special exception, the source code distributed need not include\ |
|---|
| 737 | | anything that is normally distributed (in either source or binary\ |
|---|
| 738 | | form) with the major components (compiler, kernel, and so on) of the\ |
|---|
| 739 | | operating system on which the executable runs, unless that component\ |
|---|
| 740 | | itself accompanies the executable.\ |
|---|
| 741 | | \ |
|---|
| 742 | | If distribution of executable or object code is made by offering\ |
|---|
| 743 | | access to copy from a designated place, then offering equivalent\ |
|---|
| 744 | | access to copy the source code from the same place counts as\ |
|---|
| 745 | | distribution of the source code, even though third parties are not\ |
|---|
| 746 | | compelled to copy the source along with the object code.\ |
|---|
| 747 | | \page \ |
|---|
| 748 | | 4. You may not copy, modify, sublicense, or distribute the Program\ |
|---|
| 749 | | except as expressly provided under this License. Any attempt\ |
|---|
| 750 | | otherwise to copy, modify, sublicense or distribute the Program is\ |
|---|
| 751 | | void, and will automatically terminate your rights under this License.\ |
|---|
| 752 | | However, parties who have received copies, or rights, from you under\ |
|---|
| 753 | | this License will not have their licenses terminated so long as such\ |
|---|
| 754 | | parties remain in full compliance.\ |
|---|
| 755 | | \ |
|---|
| 756 | | 5. You are not required to accept this License, since you have not\ |
|---|
| 757 | | signed it. However, nothing else grants you permission to modify or\ |
|---|
| 758 | | distribute the Program or its derivative works. These actions are\ |
|---|
| 759 | | prohibited by law if you do not accept this License. Therefore, by\ |
|---|
| 760 | | modifying or distributing the Program (or any work based on the\ |
|---|
| 761 | | Program), you indicate your acceptance of this License to do so, and\ |
|---|
| 762 | | all its terms and conditions for copying, distributing or modifying\ |
|---|
| 763 | | the Program or works based on it.\ |
|---|
| 764 | | \ |
|---|
| 765 | | 6. Each time you redistribute the Program (or any work based on the\ |
|---|
| 766 | | Program), the recipient automatically receives a license from the\ |
|---|
| 767 | | original licensor to copy, distribute or modify the Program subject to\ |
|---|
| 768 | | these terms and conditions. You may not impose any further\ |
|---|
| 769 | | restrictions on the recipients' exercise of the rights granted herein.\ |
|---|
| 770 | | You are not responsible for enforcing compliance by third parties to\ |
|---|
| 771 | | this License.\ |
|---|
| 772 | | \ |
|---|
| 773 | | 7. If, as a consequence of a court judgment or allegation of patent\ |
|---|
| 774 | | infringement or for any other reason (not limited to patent issues),\ |
|---|
| 775 | | conditions are imposed on you (whether by court order, agreement or\ |
|---|
| 776 | | otherwise) that contradict the conditions of this License, they do not\ |
|---|
| 777 | | excuse you from the conditions of this License. If you cannot\ |
|---|
| 778 | | distribute so as to satisfy simultaneously your obligations under this\ |
|---|
| 779 | | License and any other pertinent obligations, then as a consequence you\ |
|---|
| 780 | | may not distribute the Program at all. For example, if a patent\ |
|---|
| 781 | | license would not permit royalty-free redistribution of the Program by\ |
|---|
| 782 | | all those who receive copies directly or indirectly through you, then\ |
|---|
| 783 | | the only way you could satisfy both it and this License would be to\ |
|---|
| 784 | | refrain entirely from distribution of the Program.\ |
|---|
| 785 | | \ |
|---|
| 786 | | If any portion of this section is held invalid or unenforceable under\ |
|---|
| 787 | | any particular circumstance, the balance of the section is intended to\ |
|---|
| 788 | | apply and the section as a whole is intended to apply in other\ |
|---|
| 789 | | circumstances.\ |
|---|
| 790 | | \ |
|---|
| 791 | | It is not the purpose of this section to induce you to infringe any\ |
|---|
| 792 | | patents or other property right claims or to contest validity of any\ |
|---|
| 793 | | such claims; this section has the sole purpose of protecting the\ |
|---|
| 794 | | integrity of the free software distribution system, which is\ |
|---|
| 795 | | implemented by public license practices. Many people have made\ |
|---|
| 796 | | generous contributions to the wide range of software distributed\ |
|---|
| 797 | | through that system in reliance on consistent application of that\ |
|---|
| 798 | | system; it is up to the author/donor to decide if he or she is willing\ |
|---|
| 799 | | to distribute software through any other system and a licensee cannot\ |
|---|
| 800 | | impose that choice.\ |
|---|
| 801 | | \ |
|---|
| 802 | | This section is intended to make thoroughly clear what is believed to\ |
|---|
| 803 | | be a consequence of the rest of this License.\ |
|---|
| 804 | | \page \ |
|---|
| 805 | | 8. If the distribution and/or use of the Program is restricted in\ |
|---|
| 806 | | certain countries either by patents or by copyrighted interfaces, the\ |
|---|
| 807 | | original copyright holder who places the Program under this License\ |
|---|
| 808 | | may add an explicit geographical distribution limitation excluding\ |
|---|
| 809 | | those countries, so that distribution is permitted only in or among\ |
|---|
| 810 | | countries not thus excluded. In such case, this License incorporates\ |
|---|
| 811 | | the limitation as if written in the body of this License.\ |
|---|
| 812 | | \ |
|---|
| 813 | | 9. The Free Software Foundation may publish revised and/or new versions\ |
|---|
| 814 | | of the General Public License from time to time. Such new versions will\ |
|---|
| 815 | | be similar in spirit to the present version, but may differ in detail to\ |
|---|
| 816 | | address new problems or concerns.\ |
|---|
| 817 | | \ |
|---|
| 818 | | Each version is given a distinguishing version number. If the Program\ |
|---|
| 819 | | specifies a version number of this License which applies to it and "any\ |
|---|
| 820 | | later version", you have the option of following the terms and conditions\ |
|---|
| 821 | | either of that version or of any later version published by the Free\ |
|---|
| 822 | | Software Foundation. If the Program does not specify a version number of\ |
|---|
| 823 | | this License, you may choose any version ever published by the Free Software\ |
|---|
| 824 | | Foundation.\ |
|---|
| 825 | | \ |
|---|
| 826 | | 10. If you wish to incorporate parts of the Program into other free\ |
|---|
| 827 | | programs whose distribution conditions are different, write to the author\ |
|---|
| 828 | | to ask for permission. For software which is copyrighted by the Free\ |
|---|
| 829 | | Software Foundation, write to the Free Software Foundation; we sometimes\ |
|---|
| 830 | | make exceptions for this. Our decision will be guided by the two goals\ |
|---|
| 831 | | of preserving the free status of all derivatives of our free software and\ |
|---|
| 832 | | of promoting the sharing and reuse of software generally.\ |
|---|
| 833 | | \ |
|---|
| 834 | | NO WARRANTY\ |
|---|
| 835 | | \ |
|---|
| 836 | | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\ |
|---|
| 837 | | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\ |
|---|
| 838 | | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\ |
|---|
| 839 | | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\ |
|---|
| 840 | | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\ |
|---|
| 841 | | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\ |
|---|
| 842 | | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\ |
|---|
| 843 | | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\ |
|---|
| 844 | | REPAIR OR CORRECTION.\ |
|---|
| 845 | | \ |
|---|
| 846 | | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\ |
|---|
| 847 | | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\ |
|---|
| 848 | | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\ |
|---|
| 849 | | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\ |
|---|
| 850 | | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\ |
|---|
| 851 | | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\ |
|---|
| 852 | | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\ |
|---|
| 853 | | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\ |
|---|
| 854 | | POSSIBILITY OF SUCH DAMAGES.\ |
|---|
| 855 | | \ |
|---|
| 856 | | END OF TERMS AND CONDITIONS\ |
|---|
| 857 | | \page \ |
|---|
| 858 | | How to Apply These Terms to Your New Programs\ |
|---|
| 859 | | \ |
|---|
| 860 | | If you develop a new program, and you want it to be of the greatest\ |
|---|
| 861 | | possible use to the public, the best way to achieve this is to make it\ |
|---|
| 862 | | free software which everyone can redistribute and change under these terms.\ |
|---|
| 863 | | \ |
|---|
| 864 | | To do so, attach the following notices to the program. It is safest\ |
|---|
| 865 | | to attach them to the start of each source file to most effectively\ |
|---|
| 866 | | convey the exclusion of warranty; and each file should have at least\ |
|---|
| 867 | | the "copyright" line and a pointer to where the full notice is found.\ |
|---|
| 868 | | \ |
|---|
| 869 | | <one line to give the program's name and a brief idea of what it does.>\ |
|---|
| 870 | | Copyright (C) <year> <name of author>\ |
|---|

|---|
| 872 | | This program is free software; you can redistribute it and/or modify\ |
|---|
| 873 | | it under the terms of the GNU General Public License as published by\ |
|---|
| 874 | | the Free Software Foundation; either version 2 of the License, or\ |

| 875 | | (at your option) any later version.\ |
|---|
| 876 | | \ |
|---|
| 877 | | This program is distributed in the hope that it will be useful,\ |
|---|
| 878 | | but WITHOUT ANY WARRANTY; without even the implied warranty of\ |
|---|
| 879 | | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the\ |
|---|
| 880 | | GNU General Public License for more details.\ |
|---|
| 881 | | \ |
|---|
| 882 | | You should have received a copy of the GNU General Public License\ |

| 887 | | Also add information on how to contact you by electronic and paper mail.\ |
|---|

|---|
| 890 | | when it starts in an interactive mode:\ |
