692 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA |
|
693 Everyone is permitted to copy and distribute verbatim copies |
|
694 of this license document, but changing it is not allowed. |
|
695 |
|
696 |
|
697 0. PREAMBLE |
|
698 |
|
699 The purpose of this License is to make a manual, textbook, or other |
|
700 written document "free" in the sense of freedom: to assure everyone |
|
701 the effective freedom to copy and redistribute it, with or without |
|
702 modifying it, either commercially or noncommercially. Secondarily, |
|
703 this License preserves for the author and publisher a way to get |
|
704 credit for their work, while not being considered responsible for |
|
705 modifications made by others. |
|
706 |
|
707 This License is a kind of "copyleft", which means that derivative |
|
708 works of the document must themselves be free in the same sense. It |
|
709 complements the GNU General Public License, which is a copyleft |
|
710 license designed for free software. |
|
711 |
|
712 We have designed this License in order to use it for manuals for free |
|
713 software, because free software needs free documentation: a free |
|
714 program should come with manuals providing the same freedoms that the |
|
715 software does. But this License is not limited to software manuals; |
|
716 it can be used for any textual work, regardless of subject matter or |
|
717 whether it is published as a printed book. We recommend this License |
|
718 principally for works whose purpose is instruction or reference. |
|
719 |
|
720 |
|
721 1. APPLICABILITY AND DEFINITIONS |
|
722 |
|
723 This License applies to any manual or other work that contains a |
|
724 notice placed by the copyright holder saying it can be distributed |
|
725 under the terms of this License. The "Document", below, refers to any |
|
726 such manual or work. Any member of the public is a licensee, and is |
|
727 addressed as "you". |
|
728 |
|
729 A "Modified Version" of the Document means any work containing the |
|
730 Document or a portion of it, either copied verbatim, or with |
|
731 modifications and/or translated into another language. |
|
732 |
|
733 A "Secondary Section" is a named appendix or a front-matter section of |
|
734 the Document that deals exclusively with the relationship of the |
|
735 publishers or authors of the Document to the Document's overall subject |
|
736 (or to related matters) and contains nothing that could fall directly |
|
737 within that overall subject. (For example, if the Document is in part a |
|
738 textbook of mathematics, a Secondary Section may not explain any |
|
739 mathematics.) The relationship could be a matter of historical |
|
740 connection with the subject or with related matters, or of legal, |
|
741 commercial, philosophical, ethical or political position regarding |
|
742 them. |
|
743 |
|
744 The "Invariant Sections" are certain Secondary Sections whose titles |
|
745 are designated, as being those of Invariant Sections, in the notice |
|
746 that says that the Document is released under this License. |
|
747 |
|
748 The "Cover Texts" are certain short passages of text that are listed, |
|
749 as Front-Cover Texts or Back-Cover Texts, in the notice that says that |
|
750 the Document is released under this License. |
|
751 |
|
752 A "Transparent" copy of the Document means a machine-readable copy, |
|
753 represented in a format whose specification is available to the |
|
754 general public, whose contents can be viewed and edited directly and |
|
755 straightforwardly with generic text editors or (for images composed of |
|
756 pixels) generic paint programs or (for drawings) some widely available |
|
757 drawing editor, and that is suitable for input to text formatters or |
|
758 for automatic translation to a variety of formats suitable for input |
|
759 to text formatters. A copy made in an otherwise Transparent file |
|
760 format whose markup has been designed to thwart or discourage |
|
761 subsequent modification by readers is not Transparent. A copy that is |
|
762 not "Transparent" is called "Opaque". |
|
763 |
|
764 Examples of suitable formats for Transparent copies include plain |
|
765 ASCII without markup, Texinfo input format, LaTeX input format, SGML |
|
766 or XML using a publicly available DTD, and standard-conforming simple |
|
767 HTML designed for human modification. Opaque formats include |
|
768 PostScript, PDF, proprietary formats that can be read and edited only |
|
769 by proprietary word processors, SGML or XML for which the DTD and/or |
|
770 processing tools are not generally available, and the |
|
771 machine-generated HTML produced by some word processors for output |
|
772 purposes only. |
|
773 |
|
774 The "Title Page" means, for a printed book, the title page itself, |
|
775 plus such following pages as are needed to hold, legibly, the material |
|
776 this License requires to appear in the title page. For works in |
|
777 formats which do not have any title page as such, "Title Page" means |
|
778 the text near the most prominent appearance of the work's title, |
|
779 preceding the beginning of the body of the text. |
|
780 |
|
781 |
|
782 2. VERBATIM COPYING |
|
783 |
|
784 You may copy and distribute the Document in any medium, either |
|
785 commercially or noncommercially, provided that this License, the |
|
786 copyright notices, and the license notice saying this License applies |
|
787 to the Document are reproduced in all copies, and that you add no other |
|
788 conditions whatsoever to those of this License. You may not use |
|
789 technical measures to obstruct or control the reading or further |
|
790 copying of the copies you make or distribute. However, you may accept |
|
791 compensation in exchange for copies. If you distribute a large enough |
|
792 number of copies you must also follow the conditions in section 3. |
|
793 |
|
794 You may also lend copies, under the same conditions stated above, and |
|
795 you may publicly display copies. |
|
796 |
|
797 |
|
798 3. COPYING IN QUANTITY |
|
799 |
|
800 If you publish printed copies of the Document numbering more than 100, |
|
801 and the Document's license notice requires Cover Texts, you must enclose |
|
802 the copies in covers that carry, clearly and legibly, all these Cover |
|
803 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on |
|
804 the back cover. Both covers must also clearly and legibly identify |
|
805 you as the publisher of these copies. The front cover must present |
|
806 the full title with all words of the title equally prominent and |
|
807 visible. You may add other material on the covers in addition. |
|
808 Copying with changes limited to the covers, as long as they preserve |
|
809 the title of the Document and satisfy these conditions, can be treated |
|
810 as verbatim copying in other respects. |
|
811 |
|
812 If the required texts for either cover are too voluminous to fit |
|
813 legibly, you should put the first ones listed (as many as fit |
|
814 reasonably) on the actual cover, and continue the rest onto adjacent |
|
815 pages. |
|
816 |
|
817 If you publish or distribute Opaque copies of the Document numbering |
|
818 more than 100, you must either include a machine-readable Transparent |
|
819 copy along with each Opaque copy, or state in or with each Opaque copy |
|
820 a publicly-accessible computer-network location containing a complete |
|
821 Transparent copy of the Document, free of added material, which the |
|
822 general network-using public has access to download anonymously at no |
|
823 charge using public-standard network protocols. If you use the latter |
|
824 option, you must take reasonably prudent steps, when you begin |
|
825 distribution of Opaque copies in quantity, to ensure that this |
|
826 Transparent copy will remain thus accessible at the stated location |
|
827 until at least one year after the last time you distribute an Opaque |
|
828 copy (directly or through your agents or retailers) of that edition to |
|
829 the public. |
|
830 |
|
831 It is requested, but not required, that you contact the authors of the |
|
832 Document well before redistributing any large number of copies, to give |
|
833 them a chance to provide you with an updated version of the Document. |
|
834 |
|
835 |
|
836 4. MODIFICATIONS |
|
837 |
|
838 You may copy and distribute a Modified Version of the Document under |
|
839 the conditions of sections 2 and 3 above, provided that you release |
|
840 the Modified Version under precisely this License, with the Modified |
|
841 Version filling the role of the Document, thus licensing distribution |
|
842 and modification of the Modified Version to whoever possesses a copy |
|
843 of it. In addition, you must do these things in the Modified Version: |
|
844 |
|
845 A. Use in the Title Page (and on the covers, if any) a title distinct |
|
846 from that of the Document, and from those of previous versions |
|
847 (which should, if there were any, be listed in the History section |
|
848 of the Document). You may use the same title as a previous version |
|
849 if the original publisher of that version gives permission. |
|
850 B. List on the Title Page, as authors, one or more persons or entities |
|
851 responsible for authorship of the modifications in the Modified |
|
852 Version, together with at least five of the principal authors of the |
|
853 Document (all of its principal authors, if it has less than five). |
|
854 C. State on the Title page the name of the publisher of the |
|
855 Modified Version, as the publisher. |
|
856 D. Preserve all the copyright notices of the Document. |
|
857 E. Add an appropriate copyright notice for your modifications |
|
858 adjacent to the other copyright notices. |
|
859 F. Include, immediately after the copyright notices, a license notice |
|
860 giving the public permission to use the Modified Version under the |
|
861 terms of this License, in the form shown in the Addendum below. |
|
862 G. Preserve in that license notice the full lists of Invariant Sections |
|
863 and required Cover Texts given in the Document's license notice. |
|
864 H. Include an unaltered copy of this License. |
|
865 I. Preserve the section entitled "History", and its title, and add to |
|
866 it an item stating at least the title, year, new authors, and |
|
867 publisher of the Modified Version as given on the Title Page. If |
|
868 there is no section entitled "History" in the Document, create one |
|
869 stating the title, year, authors, and publisher of the Document as |
|
870 given on its Title Page, then add an item describing the Modified |
|
871 Version as stated in the previous sentence. |
|
872 J. Preserve the network location, if any, given in the Document for |
|
873 public access to a Transparent copy of the Document, and likewise |
|
874 the network locations given in the Document for previous versions |
|
875 it was based on. These may be placed in the "History" section. |
|
876 You may omit a network location for a work that was published at |
|
877 least four years before the Document itself, or if the original |
|
878 publisher of the version it refers to gives permission. |
|
879 K. In any section entitled "Acknowledgements" or "Dedications", |
|
880 preserve the section's title, and preserve in the section all the |
|
881 substance and tone of each of the contributor acknowledgements |
|
882 and/or dedications given therein. |
|
883 L. Preserve all the Invariant Sections of the Document, |
|
884 unaltered in their text and in their titles. Section numbers |
|
885 or the equivalent are not considered part of the section titles. |
|
886 M. Delete any section entitled "Endorsements". Such a section |
|
887 may not be included in the Modified Version. |
|
888 N. Do not retitle any existing section as "Endorsements" |
|
889 or to conflict in title with any Invariant Section. |
|
890 |
|
891 If the Modified Version includes new front-matter sections or |
|
892 appendices that qualify as Secondary Sections and contain no material |
|
893 copied from the Document, you may at your option designate some or all |
|
894 of these sections as invariant. To do this, add their titles to the |
|
895 list of Invariant Sections in the Modified Version's license notice. |
|
896 These titles must be distinct from any other section titles. |
|
897 |
|
898 You may add a section entitled "Endorsements", provided it contains |
|
899 nothing but endorsements of your Modified Version by various |
|
900 parties--for example, statements of peer review or that the text has |
|
901 been approved by an organization as the authoritative definition of a |
|
902 standard. |
|
903 |
|
904 You may add a passage of up to five words as a Front-Cover Text, and a |
|
905 passage of up to 25 words as a Back-Cover Text, to the end of the list |
|
906 of Cover Texts in the Modified Version. Only one passage of |
|
907 Front-Cover Text and one of Back-Cover Text may be added by (or |
|
908 through arrangements made by) any one entity. If the Document already |
|
909 includes a cover text for the same cover, previously added by you or |
|
910 by arrangement made by the same entity you are acting on behalf of, |
|
911 you may not add another; but you may replace the old one, on explicit |
|
912 permission from the previous publisher that added the old one. |
|
913 |
|
914 The author(s) and publisher(s) of the Document do not by this License |
|
915 give permission to use their names for publicity for or to assert or |
|
916 imply endorsement of any Modified Version. |
|
917 |
|
918 |
|
919 5. COMBINING DOCUMENTS |
|
920 |
|
921 You may combine the Document with other documents released under this |
|
922 License, under the terms defined in section 4 above for modified |
|
923 versions, provided that you include in the combination all of the |
|
924 Invariant Sections of all of the original documents, unmodified, and |
|
925 list them all as Invariant Sections of your combined work in its |
|
926 license notice. |
|
927 |
|
928 The combined work need only contain one copy of this License, and |
|
929 multiple identical Invariant Sections may be replaced with a single |
|
930 copy. If there are multiple Invariant Sections with the same name but |
|
931 different contents, make the title of each such section unique by |
|
932 adding at the end of it, in parentheses, the name of the original |
|
933 author or publisher of that section if known, or else a unique number. |
|
934 Make the same adjustment to the section titles in the list of |
|
935 Invariant Sections in the license notice of the combined work. |
|
936 |
|
937 In the combination, you must combine any sections entitled "History" |
|
938 in the various original documents, forming one section entitled |
|
939 "History"; likewise combine any sections entitled "Acknowledgements", |
|
940 and any sections entitled "Dedications". You must delete all sections |
|
941 entitled "Endorsements." |
|
942 |
|
943 |
|
944 6. COLLECTIONS OF DOCUMENTS |
|
945 |
|
946 You may make a collection consisting of the Document and other documents |
|
947 released under this License, and replace the individual copies of this |
|
948 License in the various documents with a single copy that is included in |
|
949 the collection, provided that you follow the rules of this License for |
|
950 verbatim copying of each of the documents in all other respects. |
|
951 |
|
952 You may extract a single document from such a collection, and distribute |
|
953 it individually under this License, provided you insert a copy of this |
|
954 License into the extracted document, and follow this License in all |
|
955 other respects regarding verbatim copying of that document. |
|
956 |
|
957 |
|
958 7. AGGREGATION WITH INDEPENDENT WORKS |
|
959 |
|
960 A compilation of the Document or its derivatives with other separate |
|
961 and independent documents or works, in or on a volume of a storage or |
|
962 distribution medium, does not as a whole count as a Modified Version |
|
963 of the Document, provided no compilation copyright is claimed for the |
|
964 compilation. Such a compilation is called an "aggregate", and this |
|
965 License does not apply to the other self-contained works thus compiled |
|
966 with the Document, on account of their being thus compiled, if they |
|
967 are not themselves derivative works of the Document. |
|
968 |
|
969 If the Cover Text requirement of section 3 is applicable to these |
|
970 copies of the Document, then if the Document is less than one quarter |
|
971 of the entire aggregate, the Document's Cover Texts may be placed on |
|
972 covers that surround only the Document within the aggregate. |
|
973 Otherwise they must appear on covers around the whole aggregate. |
|
974 |
|
975 |
|
976 8. TRANSLATION |
|
977 |
|
978 Translation is considered a kind of modification, so you may |
|
979 distribute translations of the Document under the terms of section 4. |
|
980 Replacing Invariant Sections with translations requires special |
|
981 permission from their copyright holders, but you may include |
|
982 translations of some or all Invariant Sections in addition to the |
|
983 original versions of these Invariant Sections. You may include a |
|
984 translation of this License provided that you also include the |
|
985 original English version of this License. In case of a disagreement |
|
986 between the translation and the original English version of this |
|
987 License, the original English version will prevail. |
|
988 |
|
989 |
|
990 9. TERMINATION |
|
991 |
|
992 You may not copy, modify, sublicense, or distribute the Document except |
|
993 as expressly provided for under this License. Any other attempt to |
|
994 copy, modify, sublicense or distribute the Document is void, and will |
|
995 automatically terminate your rights under this License. However, |
|
996 parties who have received copies, or rights, from you under this |
|
997 License will not have their licenses terminated so long as such |
|
998 parties remain in full compliance. |
|
999 |
|
1000 |
|
1001 10. FUTURE REVISIONS OF THIS LICENSE |
|
1002 |
|
1003 The Free Software Foundation may publish new, revised versions |
|
1004 of the GNU Free Documentation License from time to time. Such new |
|
1005 versions will be similar in spirit to the present version, but may |
|
1006 differ in detail to address new problems or concerns. See |
|
1007 http://www.gnu.org/copyleft/. |
|
1008 |
|
1009 Each version of the License is given a distinguishing version number. |
|
1010 If the Document specifies that a particular numbered version of this |
|
1011 License "or any later version" applies to it, you have the option of |
|
1012 following the terms and conditions either of that specified version or |
|
1013 of any later version that has been published (not as a draft) by the |
|
1014 Free Software Foundation. If the Document does not specify a version |
|
1015 number of this License, you may choose any version ever published (not |
|
1016 as a draft) by the Free Software Foundation. |
|
1017 |
|
1018 |
|
1019 ADDENDUM: How to use this License for your documents |
|
1020 |
|
1021 To use this License in a document you have written, include a copy of |
|
1022 the License in the document and put the following copyright and |
|
1023 license notices just after the title page: |
|
1024 |
|
1025 Copyright (c) YEAR YOUR NAME. |
|
1026 Permission is granted to copy, distribute and/or modify this document |
|
1027 under the terms of the GNU Free Documentation License, Version 1.1 |
|
1028 or any later version published by the Free Software Foundation; |
|
1029 with the Invariant Sections being LIST THEIR TITLES, with the |
|
1030 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. |
|
1031 A copy of the license is included in the section entitled "GNU |
|
1032 Free Documentation License". |
|
1033 |
|
1034 If you have no Invariant Sections, write "with no Invariant Sections" |
|
1035 instead of saying which ones are invariant. If you have no |
|
1036 Front-Cover Texts, write "no Front-Cover Texts" instead of |
|
1037 "Front-Cover Texts being LIST"; likewise for Back-Cover Texts. |
|
1038 |
|
1039 If your document contains nontrivial examples of program code, we |
|
1040 recommend releasing these examples in parallel under your choice of |
|
1041 free software license, such as the GNU General Public License, |
|
1042 to permit their use in free software. |

1052 Everyone is permitted to copy and distribute verbatim copies |

1055 |
|
1056 0. PREAMBLE |
|
1057 |
|
1058 The purpose of this License is to make a manual, textbook, or other |
|
1059 functional and useful document "free" in the sense of freedom: to |
|
1060 assure everyone the effective freedom to copy and redistribute it, |
|
1061 with or without modifying it, either commercially or noncommercially. |
|
1062 Secondarily, this License preserves for the author and publisher a way |
|
1063 to get credit for their work, while not being considered responsible |
|
1064 for modifications made by others. |
|
1065 |
|
1066 This License is a kind of "copyleft", which means that derivative |
|
1067 works of the document must themselves be free in the same sense. It |
|
1068 complements the GNU General Public License, which is a copyleft |
|
1069 license designed for free software. |
|
1070 |
|
1071 We have designed this License in order to use it for manuals for free |
|
1072 software, because free software needs free documentation: a free |
|
1073 program should come with manuals providing the same freedoms that the |
|
1074 software does. But this License is not limited to software manuals; |
|
1075 it can be used for any textual work, regardless of subject matter or |
|
1076 whether it is published as a printed book. We recommend this License |
|
1077 principally for works whose purpose is instruction or reference. |
|
1078 |
|
1079 |
|
1080 1. APPLICABILITY AND DEFINITIONS |
|
1081 |
|
1082 This License applies to any manual or other work, in any medium, that |
|
1083 contains a notice placed by the copyright holder saying it can be |
|
1084 distributed under the terms of this License. Such a notice grants a |
|
1085 world-wide, royalty-free license, unlimited in duration, to use that |
|
1086 work under the conditions stated herein. The "Document", below, |
|
1087 refers to any such manual or work. Any member of the public is a |
|
1088 licensee, and is addressed as "you". You accept the license if you |
|
1089 copy, modify or distribute the work in a way requiring permission |
|
1090 under copyright law. |
|
1091 |
|
1092 A "Modified Version" of the Document means any work containing the |
|
1093 Document or a portion of it, either copied verbatim, or with |
|
1094 modifications and/or translated into another language. |
|
1095 |
|
1096 A "Secondary Section" is a named appendix or a front-matter section of |
|
1097 the Document that deals exclusively with the relationship of the |
|
1098 publishers or authors of the Document to the Document's overall subject |
|
1099 (or to related matters) and contains nothing that could fall directly |
|
1100 within that overall subject. (Thus, if the Document is in part a |
|
1101 textbook of mathematics, a Secondary Section may not explain any |
|
1102 mathematics.) The relationship could be a matter of historical |
|
1103 connection with the subject or with related matters, or of legal, |
|
1104 commercial, philosophical, ethical or political position regarding |
|
1105 them. |
|
1106 |
|
1107 The "Invariant Sections" are certain Secondary Sections whose titles |
|
1108 are designated, as being those of Invariant Sections, in the notice |
|
1109 that says that the Document is released under this License. If a |
|
1110 section does not fit the above definition of Secondary then it is not |
|
1111 allowed to be designated as Invariant. The Document may contain zero |
|
1112 Invariant Sections. If the Document does not identify any Invariant |
|
1113 Sections then there are none. |
|
1114 |
|
1115 The "Cover Texts" are certain short passages of text that are listed, |
|
1116 as Front-Cover Texts or Back-Cover Texts, in the notice that says that |
|
1117 the Document is released under this License. A Front-Cover Text may |
|
1118 be at most 5 words, and a Back-Cover Text may be at most 25 words. |
|
1119 |
|
1120 A "Transparent" copy of the Document means a machine-readable copy, |
|
1121 represented in a format whose specification is available to the |
|
1122 general public, that is suitable for revising the document |
|
1123 straightforwardly with generic text editors or (for images composed of |
|
1124 pixels) generic paint programs or (for drawings) some widely available |
|
1125 drawing editor, and that is suitable for input to text formatters or |
|
1126 for automatic translation to a variety of formats suitable for input |
|
1127 to text formatters. A copy made in an otherwise Transparent file |
|
1128 format whose markup, or absence of markup, has been arranged to thwart |
|
1129 or discourage subsequent modification by readers is not Transparent. |
|
1130 An image format is not Transparent if used for any substantial amount |
|
1131 of text. A copy that is not "Transparent" is called "Opaque". |
|
1132 |
|
1133 Examples of suitable formats for Transparent copies include plain |
|
1134 ASCII without markup, Texinfo input format, LaTeX input format, SGML |
|
1135 or XML using a publicly available DTD, and standard-conforming simple |
|
1136 HTML, PostScript or PDF designed for human modification. Examples of |
|
1137 transparent image formats include PNG, XCF and JPG. Opaque formats |
|
1138 include proprietary formats that can be read and edited only by |
|
1139 proprietary word processors, SGML or XML for which the DTD and/or |
|
1140 processing tools are not generally available, and the |
|
1141 machine-generated HTML, PostScript or PDF produced by some word |
|
1142 processors for output purposes only. |
|
1143 |
|
1144 The "Title Page" means, for a printed book, the title page itself, |
|
1145 plus such following pages as are needed to hold, legibly, the material |
|
1146 this License requires to appear in the title page. For works in |
|
1147 formats which do not have any title page as such, "Title Page" means |
|
1148 the text near the most prominent appearance of the work's title, |
|
1149 preceding the beginning of the body of the text. |
|
1150 |
|
1151 A section "Entitled XYZ" means a named subunit of the Document whose |
|
1152 title either is precisely XYZ or contains XYZ in parentheses following |
|
1153 text that translates XYZ in another language. (Here XYZ stands for a |
|
1154 specific section name mentioned below, such as "Acknowledgements", |
|
1155 "Dedications", "Endorsements", or "History".) To "Preserve the Title" |
|
1156 of such a section when you modify the Document means that it remains a |
|
1157 section "Entitled XYZ" according to this definition. |
|
1158 |
|
1159 The Document may include Warranty Disclaimers next to the notice which |
|
1160 states that this License applies to the Document. These Warranty |
|
1161 Disclaimers are considered to be included by reference in this |
|
1162 License, but only as regards disclaiming warranties: any other |
|
1163 implication that these Warranty Disclaimers may have is void and has |
|
1164 no effect on the meaning of this License. |
|
1165 |
|
1166 |
|
1167 2. VERBATIM COPYING |
|
1168 |
|
1169 You may copy and distribute the Document in any medium, either |
|
1170 commercially or noncommercially, provided that this License, the |
|
1171 copyright notices, and the license notice saying this License applies |
|
1172 to the Document are reproduced in all copies, and that you add no other |
|
1173 conditions whatsoever to those of this License. You may not use |
|
1174 technical measures to obstruct or control the reading or further |
|
1175 copying of the copies you make or distribute. However, you may accept |
|
1176 compensation in exchange for copies. If you distribute a large enough |
|
1177 number of copies you must also follow the conditions in section 3. |
|
1178 |
|
1179 You may also lend copies, under the same conditions stated above, and |
|
1180 you may publicly display copies. |
|
1181 |
|
1182 |
|
1183 3. COPYING IN QUANTITY |
|
1184 |
|
1185 If you publish printed copies (or copies in media that commonly have |
|
1186 printed covers) of the Document, numbering more than 100, and the |
|
1187 Document's license notice requires Cover Texts, you must enclose the |
|
1188 copies in covers that carry, clearly and legibly, all these Cover |
|
1189 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on |
|
1190 the back cover. Both covers must also clearly and legibly identify |
|
1191 you as the publisher of these copies. The front cover must present |
|
1192 the full title with all words of the title equally prominent and |
|
1193 visible. You may add other material on the covers in addition. |
|
1194 Copying with changes limited to the covers, as long as they preserve |
|
1195 the title of the Document and satisfy these conditions, can be treated |
|
1196 as verbatim copying in other respects. |
|
1197 |
|
1198 If the required texts for either cover are too voluminous to fit |
|
1199 legibly, you should put the first ones listed (as many as fit |
|
1200 reasonably) on the actual cover, and continue the rest onto adjacent |
|
1201 pages. |
|
1202 |
|
1203 If you publish or distribute Opaque copies of the Document numbering |
|
1204 more than 100, you must either include a machine-readable Transparent |
|
1205 copy along with each Opaque copy, or state in or with each Opaque copy |
|
1206 a computer-network location from which the general network-using |
|
1207 public has access to download using public-standard network protocols |
|
1208 a complete Transparent copy of the Document, free of added material. |
|
1209 If you use the latter option, you must take reasonably prudent steps, |
|
1210 when you begin distribution of Opaque copies in quantity, to ensure |
|
1211 that this Transparent copy will remain thus accessible at the stated |
|
1212 location until at least one year after the last time you distribute an |
|
1213 Opaque copy (directly or through your agents or retailers) of that |
|
1214 edition to the public. |
|
1215 |
|
1216 It is requested, but not required, that you contact the authors of the |
|
1217 Document well before redistributing any large number of copies, to give |
|
1218 them a chance to provide you with an updated version of the Document. |
|
1219 |
|
1220 |
|
1221 4. MODIFICATIONS |
|
1222 |
|
1223 You may copy and distribute a Modified Version of the Document under |
|
1224 the conditions of sections 2 and 3 above, provided that you release |
|
1225 the Modified Version under precisely this License, with the Modified |
|
1226 Version filling the role of the Document, thus licensing distribution |
|
1227 and modification of the Modified Version to whoever possesses a copy |
|
1228 of it. In addition, you must do these things in the Modified Version: |
|
1229 |
|
1230 A. Use in the Title Page (and on the covers, if any) a title distinct |
|
1231 from that of the Document, and from those of previous versions |
|
1232 (which should, if there were any, be listed in the History section |
|
1233 of the Document). You may use the same title as a previous version |
|
1234 if the original publisher of that version gives permission. |
|
1235 B. List on the Title Page, as authors, one or more persons or entities |
|
1236 responsible for authorship of the modifications in the Modified |
|
1237 Version, together with at least five of the principal authors of the |
|
1238 Document (all of its principal authors, if it has fewer than five), |
|
1239 unless they release you from this requirement. |
|
1240 C. State on the Title page the name of the publisher of the |
|
1241 Modified Version, as the publisher. |
|
1242 D. Preserve all the copyright notices of the Document. |
|
1243 E. Add an appropriate copyright notice for your modifications |
|
1244 adjacent to the other copyright notices. |
|
1245 F. Include, immediately after the copyright notices, a license notice |
|
1246 giving the public permission to use the Modified Version under the |
|
1247 terms of this License, in the form shown in the Addendum below. |
|
1248 G. Preserve in that license notice the full lists of Invariant Sections |
|
1249 and required Cover Texts given in the Document's license notice. |
|
1250 H. Include an unaltered copy of this License. |
|
1251 I. Preserve the section Entitled "History", Preserve its Title, and add |
|
1252 to it an item stating at least the title, year, new authors, and |
|
1253 publisher of the Modified Version as given on the Title Page. If |
|
1254 there is no section Entitled "History" in the Document, create one |
|
1255 stating the title, year, authors, and publisher of the Document as |
|
1256 given on its Title Page, then add an item describing the Modified |
|
1257 Version as stated in the previous sentence. |
|
1258 J. Preserve the network location, if any, given in the Document for |
|
1259 public access to a Transparent copy of the Document, and likewise |
|
1260 the network locations given in the Document for previous versions |
|
1261 it was based on. These may be placed in the "History" section. |
|
1262 You may omit a network location for a work that was published at |
|
1263 least four years before the Document itself, or if the original |
|
1264 publisher of the version it refers to gives permission. |
|
1265 K. For any section Entitled "Acknowledgements" or "Dedications", |
|
1266 Preserve the Title of the section, and preserve in the section all |
|
1267 the substance and tone of each of the contributor acknowledgements |
|
1268 and/or dedications given therein. |
|
1269 L. Preserve all the Invariant Sections of the Document, |
|
1270 unaltered in their text and in their titles. Section numbers |
|
1271 or the equivalent are not considered part of the section titles. |
|
1272 M. Delete any section Entitled "Endorsements". Such a section |
|
1273 may not be included in the Modified Version. |
|
1274 N. Do not retitle any existing section to be Entitled "Endorsements" |
|
1275 or to conflict in title with any Invariant Section. |
|
1276 O. Preserve any Warranty Disclaimers. |
|
1277 |
|
1278 If the Modified Version includes new front-matter sections or |
|
1279 appendices that qualify as Secondary Sections and contain no material |
|
1280 copied from the Document, you may at your option designate some or all |
|
1281 of these sections as invariant. To do this, add their titles to the |
|
1282 list of Invariant Sections in the Modified Version's license notice. |
|
1283 These titles must be distinct from any other section titles. |
|
1284 |
|
1285 You may add a section Entitled "Endorsements", provided it contains |
|
1286 nothing but endorsements of your Modified Version by various |
|
1287 parties--for example, statements of peer review or that the text has |
|
1288 been approved by an organization as the authoritative definition of a |
|
1289 standard. |
|
1290 |
|
1291 You may add a passage of up to five words as a Front-Cover Text, and a |
|
1292 passage of up to 25 words as a Back-Cover Text, to the end of the list |
|
1293 of Cover Texts in the Modified Version. Only one passage of |
|
1294 Front-Cover Text and one of Back-Cover Text may be added by (or |
|
1295 through arrangements made by) any one entity. If the Document already |
|
1296 includes a cover text for the same cover, previously added by you or |
|
1297 by arrangement made by the same entity you are acting on behalf of, |
|
1298 you may not add another; but you may replace the old one, on explicit |
|
1299 permission from the previous publisher that added the old one. |
|
1300 |
|
1301 The author(s) and publisher(s) of the Document do not by this License |
|
1302 give permission to use their names for publicity for or to assert or |
|
1303 imply endorsement of any Modified Version. |
|
1304 |
|
1305 |
|
1306 5. COMBINING DOCUMENTS |
|
1307 |
|
1308 You may combine the Document with other documents released under this |
|
1309 License, under the terms defined in section 4 above for modified |
|
1310 versions, provided that you include in the combination all of the |
|
1311 Invariant Sections of all of the original documents, unmodified, and |
|
1312 list them all as Invariant Sections of your combined work in its |
|
1313 license notice, and that you preserve all their Warranty Disclaimers. |
|
1314 |
|
1315 The combined work need only contain one copy of this License, and |
|
1316 multiple identical Invariant Sections may be replaced with a single |
|
1317 copy. If there are multiple Invariant Sections with the same name but |
|
1318 different contents, make the title of each such section unique by |
|
1319 adding at the end of it, in parentheses, the name of the original |
|
1320 author or publisher of that section if known, or else a unique number. |
|
1321 Make the same adjustment to the section titles in the list of |
|
1322 Invariant Sections in the license notice of the combined work. |
|
1323 |
|
1324 In the combination, you must combine any sections Entitled "History" |
|
1325 in the various original documents, forming one section Entitled |
|
1326 "History"; likewise combine any sections Entitled "Acknowledgements", |
|
1327 and any sections Entitled "Dedications". You must delete all sections |
|
1328 Entitled "Endorsements". |
|
1329 |
|
1330 |
|
1331 6. COLLECTIONS OF DOCUMENTS |
|
1332 |
|
1333 You may make a collection consisting of the Document and other documents |
|
1334 released under this License, and replace the individual copies of this |
|
1335 License in the various documents with a single copy that is included in |
|
1336 the collection, provided that you follow the rules of this License for |
|
1337 verbatim copying of each of the documents in all other respects. |
|
1338 |
|
1339 You may extract a single document from such a collection, and distribute |
|
1340 it individually under this License, provided you insert a copy of this |
|
1341 License into the extracted document, and follow this License in all |
|
1342 other respects regarding verbatim copying of that document. |
|
1343 |
|
1344 |
|
1345 7. AGGREGATION WITH INDEPENDENT WORKS |
|
1346 |
|
1347 A compilation of the Document or its derivatives with other separate |
|
1348 and independent documents or works, in or on a volume of a storage or |
|
1349 distribution medium, is called an "aggregate" if the copyright |
|
1350 resulting from the compilation is not used to limit the legal rights |
|
1351 of the compilation's users beyond what the individual works permit. |
|
1352 When the Document is included in an aggregate, this License does not |
|
1353 apply to the other works in the aggregate which are not themselves |
|
1354 derivative works of the Document. |
|
1355 |
|
1356 If the Cover Text requirement of section 3 is applicable to these |
|
1357 copies of the Document, then if the Document is less than one half of |
|
1358 the entire aggregate, the Document's Cover Texts may be placed on |
|
1359 covers that bracket the Document within the aggregate, or the |
|
1360 electronic equivalent of covers if the Document is in electronic form. |
|
1361 Otherwise they must appear on printed covers that bracket the whole |
|
1362 aggregate. |
|
1363 |
|
1364 |
|
1365 8. TRANSLATION |
|
1366 |
|
1367 Translation is considered a kind of modification, so you may |
|
1368 distribute translations of the Document under the terms of section 4. |
|
1369 Replacing Invariant Sections with translations requires special |
|
1370 permission from their copyright holders, but you may include |
|
1371 translations of some or all Invariant Sections in addition to the |
|
1372 original versions of these Invariant Sections. You may include a |
|
1373 translation of this License, and all the license notices in the |
|
1374 Document, and any Warranty Disclaimers, provided that you also include |
|
1375 the original English version of this License and the original versions |
|
1376 of those notices and disclaimers. In case of a disagreement between |
|
1377 the translation and the original version of this License or a notice |
|
1378 or disclaimer, the original version will prevail. |
|
1379 |
|
1380 If a section in the Document is Entitled "Acknowledgements", |
|
1381 "Dedications", or "History", the requirement (section 4) to Preserve |
|
1382 its Title (section 1) will typically require changing the actual |
|
1383 title. |
|
1384 |
|
1385 |
|
1386 9. TERMINATION |
|
1387 |
|
1388 You may not copy, modify, sublicense, or distribute the Document except |
|
1389 as expressly provided for under this License. Any other attempt to |
|
1390 copy, modify, sublicense or distribute the Document is void, and will |
|
1391 automatically terminate your rights under this License. However, |
|
1392 parties who have received copies, or rights, from you under this |
|
1393 License will not have their licenses terminated so long as such |
|
1394 parties remain in full compliance. |
|
1395 |
|
1396 |
|
1397 10. FUTURE REVISIONS OF THIS LICENSE |
|
1398 |
|
1399 The Free Software Foundation may publish new, revised versions |
|
1400 of the GNU Free Documentation License from time to time. Such new |
|
1401 versions will be similar in spirit to the present version, but may |
|
1402 differ in detail to address new problems or concerns. See |
|
1403 http://www.gnu.org/copyleft/. |
|
1404 |
|
1405 Each version of the License is given a distinguishing version number. |
|
1406 If the Document specifies that a particular numbered version of this |
|
1407 License "or any later version" applies to it, you have the option of |
|
1408 following the terms and conditions either of that specified version or |
|
1409 of any later version that has been published (not as a draft) by the |
|
1410 Free Software Foundation. If the Document does not specify a version |
|
1411 number of this License, you may choose any version ever published (not |
|
1412 as a draft) by the Free Software Foundation. |
|
1413 |
|
1414 |
|
1415 ADDENDUM: How to use this License for your documents |
|
1416 |
|
1417 To use this License in a document you have written, include a copy of |
|
1418 the License in the document and put the following copyright and |
|
1419 license notices just after the title page: |
|
1420 |
|
1421 Copyright (c) YEAR YOUR NAME. |
|
1422 Permission is granted to copy, distribute and/or modify this document |
|
1423 under the terms of the GNU Free Documentation License, Version 1.2 |
|
1424 or any later version published by the Free Software Foundation; |
|
1425 with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. |
|
1426 A copy of the license is included in the section entitled "GNU |
|
1427 Free Documentation License". |
|
1428 |
|
1429 If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, |
|
1430 replace the "with...Texts." line with this: |
|
1431 |
|
1432 with the Invariant Sections being LIST THEIR TITLES, with the |
|
1433 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. |
|
1434 |
|
1435 If you have Invariant Sections without Cover Texts, or some other |
|
1436 combination of the three, merge those two alternatives to suit the |
|
1437 situation. |
|
1438 |
|
1439 If your document contains nontrivial examples of program code, we |
|
1440 recommend releasing these examples in parallel under your choice of |
|
1441 free software license, such as the GNU General Public License, |
|
1442 to permit their use in free software. |
