| | 800 | 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA |
| | 801 | Everyone is permitted to copy and distribute verbatim copies |
| | 802 | of this license document, but changing it is not allowed. |
| | 803 | |
| | 804 | Preamble |
| | 805 | |
| | 806 | The licenses for most software are designed to take away your |
| | 807 | freedom to share and change it. By contrast, the GNU General Public |
| | 808 | License is intended to guarantee your freedom to share and change free |
| | 809 | software--to make sure the software is free for all its users. This |
| | 810 | General Public License applies to most of the Free Software |
| | 811 | Foundation's software and to any other program whose authors commit to |
| | 812 | using it. (Some other Free Software Foundation software is covered by |
| | 813 | the GNU Library General Public License instead.) You can apply it to |
| | 814 | your programs, too. |
| | 815 | |
| | 816 | When we speak of free software, we are referring to freedom, not |
| | 817 | price. Our General Public Licenses are designed to make sure that you |
| | 818 | have the freedom to distribute copies of free software (and charge for |
| | 819 | this service if you wish), that you receive source code or can get it |
| | 820 | if you want it, that you can change the software or use pieces of it |
| | 821 | in new free programs; and that you know you can do these things. |
| | 822 | |
| | 823 | To protect your rights, we need to make restrictions that forbid |
| | 824 | anyone to deny you these rights or to ask you to surrender the rights. |
| | 825 | These restrictions translate to certain responsibilities for you if you |
| | 826 | distribute copies of the software, or if you modify it. |
| | 827 | |
| | 828 | For example, if you distribute copies of such a program, whether |
| | 829 | gratis or for a fee, you must give the recipients all the rights that |
| | 830 | you have. You must make sure that they, too, receive or can get the |
| | 831 | source code. And you must show them these terms so they know their |
| | 832 | rights. |
| | 833 | |
| | 834 | We protect your rights with two steps: (1) copyright the software, and |
| | 835 | (2) offer you this license which gives you legal permission to copy, |
| | 836 | distribute and/or modify the software. |
| | 837 | |
| | 838 | Also, for each author's protection and ours, we want to make certain |
| | 839 | that everyone understands that there is no warranty for this free |
| | 840 | software. If the software is modified by someone else and passed on, we |
| | 841 | want its recipients to know that what they have is not the original, so |
| | 842 | that any problems introduced by others will not reflect on the original |
| | 843 | authors' reputations. |
| | 844 | |
| | 845 | Finally, any free program is threatened constantly by software |
| | 846 | patents. We wish to avoid the danger that redistributors of a free |
| | 847 | program will individually obtain patent licenses, in effect making the |
| | 848 | program proprietary. To prevent this, we have made it clear that any |
| | 849 | patent must be licensed for everyone's free use or not licensed at all. |
| | 850 | |
| | 851 | The precise terms and conditions for copying, distribution and |
| | 852 | modification follow. |
| | 853 | |
| | 854 | GNU GENERAL PUBLIC LICENSE |
| | 855 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
| | 856 | |
| | 857 | 0. This License applies to any program or other work which contains |
| | 858 | a notice placed by the copyright holder saying it may be distributed |
| | 859 | under the terms of this General Public License. The "Program", below, |
| | 860 | refers to any such program or work, and a "work based on the Program" |
| | 861 | means either the Program or any derivative work under copyright law: |
| | 862 | that is to say, a work containing the Program or a portion of it, |
| | 863 | either verbatim or with modifications and/or translated into another |
| | 864 | language. (Hereinafter, translation is included without limitation in |
| | 865 | the term "modification".) Each licensee is addressed as "you". |
| | 866 | |
| | 867 | Activities other than copying, distribution and modification are not |
| | 868 | covered by this License; they are outside its scope. The act of |
| | 869 | running the Program is not restricted, and the output from the Program |
| | 870 | is covered only if its contents constitute a work based on the |
| | 871 | Program (independent of having been made by running the Program). |
| | 872 | Whether that is true depends on what the Program does. |
| | 873 | |
| | 874 | 1. You may copy and distribute verbatim copies of the Program's |
| | 875 | source code as you receive it, in any medium, provided that you |
| | 876 | conspicuously and appropriately publish on each copy an appropriate |
| | 877 | copyright notice and disclaimer of warranty; keep intact all the |
| | 878 | notices that refer to this License and to the absence of any warranty; |
| | 879 | and give any other recipients of the Program a copy of this License |
| | 880 | along with the Program. |
| | 881 | |
| | 882 | You may charge a fee for the physical act of transferring a copy, and |
| | 883 | you may at your option offer warranty protection in exchange for a fee. |
| | 884 | |
| | 885 | 2. You may modify your copy or copies of the Program or any portion |
| | 886 | of it, thus forming a work based on the Program, and copy and |
| | 887 | distribute such modifications or work under the terms of Section 1 |
| | 888 | above, provided that you also meet all of these conditions: |
| | 889 | |
| | 890 | a) You must cause the modified files to carry prominent notices |
| | 891 | stating that you changed the files and the date of any change. |
| | 892 | |
| | 893 | b) You must cause any work that you distribute or publish, that in |
| | 894 | whole or in part contains or is derived from the Program or any |
| | 895 | part thereof, to be licensed as a whole at no charge to all third |
| | 896 | parties under the terms of this License. |
| | 897 | |
| | 898 | c) If the modified program normally reads commands interactively |
| | 899 | when run, you must cause it, when started running for such |
| | 900 | interactive use in the most ordinary way, to print or display an |
| | 901 | announcement including an appropriate copyright notice and a |
| | 902 | notice that there is no warranty (or else, saying that you provide |
| | 903 | a warranty) and that users may redistribute the program under |
| | 904 | these conditions, and telling the user how to view a copy of this |
| | 905 | License. (Exception: if the Program itself is interactive but |
| | 906 | does not normally print such an announcement, your work based on |
| | 907 | the Program is not required to print an announcement.) |
| | 908 | |
| | 909 | These requirements apply to the modified work as a whole. If |
| | 910 | identifiable sections of that work are not derived from the Program, |
| | 911 | and can be reasonably considered independent and separate works in |
| | 912 | themselves, then this License, and its terms, do not apply to those |
| | 913 | sections when you distribute them as separate works. But when you |
| | 914 | distribute the same sections as part of a whole which is a work based |
| | 915 | on the Program, the distribution of the whole must be on the terms of |
| | 916 | this License, whose permissions for other licensees extend to the |
| | 917 | entire whole, and thus to each and every part regardless of who wrote it. |
| | 918 | |
| | 919 | Thus, it is not the intent of this section to claim rights or contest |
| | 920 | your rights to work written entirely by you; rather, the intent is to |
| | 921 | exercise the right to control the distribution of derivative or |
| | 922 | collective works based on the Program. |
| | 923 | |
| | 924 | In addition, mere aggregation of another work not based on the Program |
| | 925 | with the Program (or with a work based on the Program) on a volume of |
| | 926 | a storage or distribution medium does not bring the other work under |
| | 927 | the scope of this License. |
| | 928 | |
| | 929 | 3. You may copy and distribute the Program (or a work based on it, |
| | 930 | under Section 2) in object code or executable form under the terms of |
| | 931 | Sections 1 and 2 above provided that you also do one of the following: |
| | 932 | |
| | 933 | a) Accompany it with the complete corresponding machine-readable |
| | 934 | source code, which must be distributed under the terms of Sections |
| | 935 | 1 and 2 above on a medium customarily used for software interchange; or, |
| | 936 | |
| | 937 | b) Accompany it with a written offer, valid for at least three |
| | 938 | years, to give any third party, for a charge no more than your |
| | 939 | cost of physically performing source distribution, a complete |
| | 940 | machine-readable copy of the corresponding source code, to be |
| | 941 | distributed under the terms of Sections 1 and 2 above on a medium |
| | 942 | customarily used for software interchange; or, |
| | 943 | |
| | 944 | c) Accompany it with the information you received as to the offer |
| | 945 | to distribute corresponding source code. (This alternative is |
| | 946 | allowed only for noncommercial distribution and only if you |
| | 947 | received the program in object code or executable form with such |
| | 948 | an offer, in accord with Subsection b above.) |
| | 949 | |
| | 950 | The source code for a work means the preferred form of the work for |
| | 951 | making modifications to it. For an executable work, complete source |
| | 952 | code means all the source code for all modules it contains, plus any |
| | 953 | associated interface definition files, plus the scripts used to |
| | 954 | control compilation and installation of the executable. However, as a |
| | 955 | special exception, the source code distributed need not include |
| | 956 | anything that is normally distributed (in either source or binary |
| | 957 | form) with the major components (compiler, kernel, and so on) of the |
| | 958 | operating system on which the executable runs, unless that component |
| | 959 | itself accompanies the executable. |
| | 960 | |
| | 961 | If distribution of executable or object code is made by offering |
| | 962 | access to copy from a designated place, then offering equivalent |
| | 963 | access to copy the source code from the same place counts as |
| | 964 | distribution of the source code, even though third parties are not |
| | 965 | compelled to copy the source along with the object code. |
| | 966 | |
| | 967 | 4. You may not copy, modify, sublicense, or distribute the Program |
| | 968 | except as expressly provided under this License. Any attempt |
| | 969 | otherwise to copy, modify, sublicense or distribute the Program is |
| | 970 | void, and will automatically terminate your rights under this License. |
| | 971 | However, parties who have received copies, or rights, from you under |
| | 972 | this License will not have their licenses terminated so long as such |
| | 973 | parties remain in full compliance. |
| | 974 | |
| | 975 | 5. You are not required to accept this License, since you have not |
| | 976 | signed it. However, nothing else grants you permission to modify or |
| | 977 | distribute the Program or its derivative works. These actions are |
| | 978 | prohibited by law if you do not accept this License. Therefore, by |
| | 979 | modifying or distributing the Program (or any work based on the |
| | 980 | Program), you indicate your acceptance of this License to do so, and |
| | 981 | all its terms and conditions for copying, distributing or modifying |
| | 982 | the Program or works based on it. |
| | 983 | |
| | 984 | 6. Each time you redistribute the Program (or any work based on the |
| | 985 | Program), the recipient automatically receives a license from the |
| | 986 | original licensor to copy, distribute or modify the Program subject to |
| | 987 | these terms and conditions. You may not impose any further |
| | 988 | restrictions on the recipients' exercise of the rights granted herein. |
| | 989 | You are not responsible for enforcing compliance by third parties to |
| | 990 | this License. |
| | 991 | |
| | 992 | 7. If, as a consequence of a court judgment or allegation of patent |
| | 993 | infringement or for any other reason (not limited to patent issues), |
| | 994 | conditions are imposed on you (whether by court order, agreement or |
| | 995 | otherwise) that contradict the conditions of this License, they do not |
| | 996 | excuse you from the conditions of this License. If you cannot |
| | 997 | distribute so as to satisfy simultaneously your obligations under this |
| | 998 | License and any other pertinent obligations, then as a consequence you |
| | 999 | may not distribute the Program at all. For example, if a patent |
| | 1000 | license would not permit royalty-free redistribution of the Program by |
| | 1001 | all those who receive copies directly or indirectly through you, then |
| | 1002 | the only way you could satisfy both it and this License would be to |
| | 1003 | refrain entirely from distribution of the Program. |
| | 1004 | |
| | 1005 | If any portion of this section is held invalid or unenforceable under |
| | 1006 | any particular circumstance, the balance of the section is intended to |
| | 1007 | apply and the section as a whole is intended to apply in other |
| | 1008 | circumstances. |
| | 1009 | |
| | 1010 | It is not the purpose of this section to induce you to infringe any |
| | 1011 | patents or other property right claims or to contest validity of any |
| | 1012 | such claims; this section has the sole purpose of protecting the |
| | 1013 | integrity of the free software distribution system, which is |
| | 1014 | implemented by public license practices. Many people have made |
| | 1015 | generous contributions to the wide range of software distributed |
| | 1016 | through that system in reliance on consistent application of that |
| | 1017 | system; it is up to the author/donor to decide if he or she is willing |
| | 1018 | to distribute software through any other system and a licensee cannot |
| | 1019 | impose that choice. |
| | 1020 | |
| | 1021 | This section is intended to make thoroughly clear what is believed to |
| | 1022 | be a consequence of the rest of this License. |
| | 1023 | |
| | 1024 | 8. If the distribution and/or use of the Program is restricted in |
| | 1025 | certain countries either by patents or by copyrighted interfaces, the |
| | 1026 | original copyright holder who places the Program under this License |
| | 1027 | may add an explicit geographical distribution limitation excluding |
| | 1028 | those countries, so that distribution is permitted only in or among |
| | 1029 | countries not thus excluded. In such case, this License incorporates |
| | 1030 | the limitation as if written in the body of this License. |
| | 1031 | |
| | 1032 | 9. The Free Software Foundation may publish revised and/or new versions |
| | 1033 | of the General Public License from time to time. Such new versions will |
| | 1034 | be similar in spirit to the present version, but may differ in detail to |
| | 1035 | address new problems or concerns. |
| | 1036 | |
| | 1037 | Each version is given a distinguishing version number. If the Program |
| | 1038 | specifies a version number of this License which applies to it and "any |
| | 1039 | later version", you have the option of following the terms and conditions |
| | 1040 | either of that version or of any later version published by the Free |
| | 1041 | Software Foundation. If the Program does not specify a version number of |
| | 1042 | this License, you may choose any version ever published by the Free Software |
| | 1043 | Foundation. |
| | 1044 | |
| | 1045 | 10. If you wish to incorporate parts of the Program into other free |
| | 1046 | programs whose distribution conditions are different, write to the author |
| | 1047 | to ask for permission. For software which is copyrighted by the Free |
| | 1048 | Software Foundation, write to the Free Software Foundation; we sometimes |
| | 1049 | make exceptions for this. Our decision will be guided by the two goals |
| | 1050 | of preserving the free status of all derivatives of our free software and |
| | 1051 | of promoting the sharing and reuse of software generally. |
| | 1052 | |
| | 1053 | NO WARRANTY |
| | 1054 | |
| | 1055 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY |
| | 1056 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN |
| | 1057 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES |
| | 1058 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED |
| | 1059 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
| | 1060 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS |
| | 1061 | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE |
| | 1062 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, |
| | 1063 | REPAIR OR CORRECTION. |
| | 1064 | |
| | 1065 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
| | 1066 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR |
| | 1067 | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, |
| | 1068 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING |
| | 1069 | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED |
| | 1070 | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY |
| | 1071 | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER |
| | 1072 | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE |
| | 1073 | POSSIBILITY OF SUCH DAMAGES. |
| | 1074 | |
| | 1075 | END OF TERMS AND CONDITIONS |
| | 1076 | |
| | 1077 | How to Apply These Terms to Your New Programs |
| | 1078 | |
| | 1079 | If you develop a new program, and you want it to be of the greatest |
| | 1080 | possible use to the public, the best way to achieve this is to make it |
| | 1081 | free software which everyone can redistribute and change under these terms. |
| | 1082 | |
| | 1083 | To do so, attach the following notices to the program. It is safest |
| | 1084 | to attach them to the start of each source file to most effectively |
| | 1085 | convey the exclusion of warranty; and each file should have at least |
| | 1086 | the "copyright" line and a pointer to where the full notice is found. |
| | 1087 | |
| | 1088 | <one line to give the program's name and a brief idea of what it does.> |
| | 1089 | Copyright (C) <year> <name of author> |
| | 1090 | |
| | 1091 | This program is free software; you can redistribute it and/or modify |
| | 1092 | it under the terms of the GNU General Public License as published by |
| | 1093 | the Free Software Foundation; either version 2 of the License, or |
| | 1094 | (at your option) any later version. |
| | 1095 | |
| | 1096 | This program is distributed in the hope that it will be useful, |
| | 1097 | but WITHOUT ANY WARRANTY; without even the implied warranty of |
| | 1098 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
| | 1099 | GNU General Public License for more details. |
| | 1100 | |
| | 1101 | You should have received a copy of the GNU General Public License |
| | 1102 | along with this program; if not, write to the Free Software |
| | 1103 | Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA |
| | 1104 | |
| | 1105 | |
| | 1106 | Also add information on how to contact you by electronic and paper mail. |
| | 1107 | |
| | 1108 | If the program is interactive, make it output a short notice like this |
| | 1109 | when it starts in an interactive mode: |
| | 1110 | |
| | 1111 | Gnomovision version 69, Copyright (C) year name of author |
| | 1112 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. |
| | 1113 | This is free software, and you are welcome to redistribute it |
| | 1114 | under certain conditions; type `show c' for details. |
| | 1115 | |
| | 1116 | The hypothetical commands `show w' and `show c' should show the appropriate |
| | 1117 | parts of the General Public License. Of course, the commands you use may |
| | 1118 | be called something other than `show w' and `show c'; they could even be |
| | 1119 | mouse-clicks or menu items--whatever suits your program. |
| | 1120 | |
| | 1121 | You should also get your employer (if you work as a programmer) or your |
| | 1122 | school, if any, to sign a "copyright disclaimer" for the program, if |
| | 1123 | necessary. Here is a sample; alter the names: |
| | 1124 | |
| | 1125 | Yoyodyne, Inc., hereby disclaims all copyright interest in the program |
| | 1126 | `Gnomovision' (which makes passes at compilers) written by James Hacker. |
| | 1127 | |

| | 1130 | |
| | 1131 | This General Public License does not permit incorporating your program into |
| | 1132 | proprietary programs. If your program is a subroutine library, you may |
| | 1133 | consider it more useful to permit linking proprietary applications with the |
| | 1134 | library. If this is what you want to do, use the GNU Library General |
| | 1135 | Public License instead of this License. |
