814 How to Apply These Terms to Your New Libraries |
|
815 |
|
816 If you develop a new library, and you want it to be of the greatest |
|
817 possible use to the public, we recommend making it free software that |
|
818 everyone can redistribute and change. You can do so by permitting |
|
819 redistribution under these terms (or, alternatively, under the terms of the |
|
820 ordinary General Public License). |
|
821 |
|
822 To apply these terms, attach the following notices to the library. It is |
|
823 safest to attach them to the start of each source file to most effectively |
|
824 convey the exclusion of warranty; and each file should have at least the |
|
825 "copyright" line and a pointer to where the full notice is found. |
|
826 |
|
827 <one line to give the library's name and a brief idea of what it does.> |

|
836 but WITHOUT ANY WARRANTY; without even the implied warranty of |

|
843 |
|
844 Also add information on how to contact you by electronic and paper mail. |
|
845 |
|
846 You should also get your employer (if you work as a programmer) or your |
|
847 school, if any, to sign a "copyright disclaimer" for the library, if |
|
848 necessary. Here is a sample; alter the names: |

873 with or without modifying it, either commercially or noncommercially. |
|
874 Secondarily, this License preserves for the author and publisher a way |
|
875 to get credit for their work, while not being considered responsible |
|
876 for modifications made by others. |
|
877 |
|
878 This License is a kind of "copyleft", which means that derivative |
|
879 works of the document must themselves be free in the same sense. It |
|
880 complements the GNU General Public License, which is a copyleft |
|
881 license designed for free software. |
|
882 |
|
883 We have designed this License in order to use it for manuals for free |
|
884 software, because free software needs free documentation: a free |
|
885 program should come with manuals providing the same freedoms that the |
|
886 software does. But this License is not limited to software manuals; |
|
887 it can be used for any textual work, regardless of subject matter or |
|
888 whether it is published as a printed book. We recommend this License |
|
889 principally for works whose purpose is instruction or reference. |
|
890 |
|
891 |
|
892 1. APPLICABILITY AND DEFINITIONS |
|
893 |
|
894 This License applies to any manual or other work, in any medium, that |
|
895 contains a notice placed by the copyright holder saying it can be |
|
896 distributed under the terms of this License. Such a notice grants a |
|
897 world-wide, royalty-free license, unlimited in duration, to use that |
|
898 work under the conditions stated herein. The "Document", below, |
|
899 refers to any such manual or work. Any member of the public is a |
|
900 licensee, and is addressed as "you". You accept the license if you |
|
901 copy, modify or distribute the work in a way requiring permission |
|
902 under copyright law. |
|
903 |
|
904 A "Modified Version" of the Document means any work containing the |
|
905 Document or a portion of it, either copied verbatim, or with |
|
906 modifications and/or translated into another language. |
|
907 |
|
908 A "Secondary Section" is a named appendix or a front-matter section of |
|
909 the Document that deals exclusively with the relationship of the |
|
910 publishers or authors of the Document to the Document's overall |
|
911 subject (or to related matters) and contains nothing that could fall |
|
912 directly within that overall subject. (Thus, if the Document is in |
|
913 part a textbook of mathematics, a Secondary Section may not explain |
|
914 any mathematics.) The relationship could be a matter of historical |
|
915 connection with the subject or with related matters, or of legal, |
|
916 commercial, philosophical, ethical or political position regarding |
|
917 them. |
|
918 |
|
919 The "Invariant Sections" are certain Secondary Sections whose titles |
|
920 are designated, as being those of Invariant Sections, in the notice |
|
921 that says that the Document is released under this License. If a |
|
922 section does not fit the above definition of Secondary then it is not |
|
923 allowed to be designated as Invariant. The Document may contain zero |
|
924 Invariant Sections. If the Document does not identify any Invariant |
|
925 Sections then there are none. |
|
926 |
|
927 The "Cover Texts" are certain short passages of text that are listed, |
|
928 as Front-Cover Texts or Back-Cover Texts, in the notice that says that |
|
929 the Document is released under this License. A Front-Cover Text may |
|
930 be at most 5 words, and a Back-Cover Text may be at most 25 words. |
|
931 |
|
932 A "Transparent" copy of the Document means a machine-readable copy, |
|
933 represented in a format whose specification is available to the |
|
934 general public, that is suitable for revising the document |
|
935 straightforwardly with generic text editors or (for images composed of |
|
936 pixels) generic paint programs or (for drawings) some widely available |
|
937 drawing editor, and that is suitable for input to text formatters or |
|
938 for automatic translation to a variety of formats suitable for input |
|
939 to text formatters. A copy made in an otherwise Transparent file |
|
940 format whose markup, or absence of markup, has been arranged to thwart |
|
941 or discourage subsequent modification by readers is not Transparent. |
|
942 An image format is not Transparent if used for any substantial amount |
|
943 of text. A copy that is not "Transparent" is called "Opaque". |
|
944 |
|
945 Examples of suitable formats for Transparent copies include plain |
|
946 ASCII without markup, Texinfo input format, LaTeX input format, SGML |
|
947 or XML using a publicly available DTD, and standard-conforming simple |
|
948 HTML, PostScript or PDF designed for human modification. Examples of |
|
949 transparent image formats include PNG, XCF and JPG. Opaque formats |
|
950 include proprietary formats that can be read and edited only by |
|
951 proprietary word processors, SGML or XML for which the DTD and/or |
|
952 processing tools are not generally available, and the |
|
953 machine-generated HTML, PostScript or PDF produced by some word |
|
954 processors for output purposes only. |
|
955 |
|
956 The "Title Page" means, for a printed book, the title page itself, |
|
957 plus such following pages as are needed to hold, legibly, the material |
|
958 this License requires to appear in the title page. For works in |
|
959 formats which do not have any title page as such, "Title Page" means |
|
960 the text near the most prominent appearance of the work's title, |
|
961 preceding the beginning of the body of the text. |
|
962 |
|
963 The "publisher" means any person or entity that distributes copies of |
|
964 the Document to the public. |
|
965 |
|
966 A section "Entitled XYZ" means a named subunit of the Document whose |
|
967 title either is precisely XYZ or contains XYZ in parentheses following |
|
968 text that translates XYZ in another language. (Here XYZ stands for a |
|
969 specific section name mentioned below, such as "Acknowledgements", |
|
970 "Dedications", "Endorsements", or "History".) To "Preserve the Title" |
|
971 of such a section when you modify the Document means that it remains a |
|
972 section "Entitled XYZ" according to this definition. |
|
973 |
|
974 The Document may include Warranty Disclaimers next to the notice which |
|
975 states that this License applies to the Document. These Warranty |
|
976 Disclaimers are considered to be included by reference in this |
|
977 License, but only as regards disclaiming warranties: any other |
|
978 implication that these Warranty Disclaimers may have is void and has |
|
979 no effect on the meaning of this License. |
|
980 |
|
981 2. VERBATIM COPYING |
|
982 |
|
983 You may copy and distribute the Document in any medium, either |
|
984 commercially or noncommercially, provided that this License, the |
|
985 copyright notices, and the license notice saying this License applies |
|
986 to the Document are reproduced in all copies, and that you add no |
|
987 other conditions whatsoever to those of this License. You may not use |
|
988 technical measures to obstruct or control the reading or further |
|
989 copying of the copies you make or distribute. However, you may accept |
|
990 compensation in exchange for copies. If you distribute a large enough |
|
991 number of copies you must also follow the conditions in section 3. |
|
992 |
|
993 You may also lend copies, under the same conditions stated above, and |
|
994 you may publicly display copies. |
|
995 |
|
996 |
|
997 3. COPYING IN QUANTITY |
|
998 |
|
999 If you publish printed copies (or copies in media that commonly have |
|
1000 printed covers) of the Document, numbering more than 100, and the |
|
1001 Document's license notice requires Cover Texts, you must enclose the |
|
1002 copies in covers that carry, clearly and legibly, all these Cover |
|
1003 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on |
|
1004 the back cover. Both covers must also clearly and legibly identify |
|
1005 you as the publisher of these copies. The front cover must present |
|
1006 the full title with all words of the title equally prominent and |
|
1007 visible. You may add other material on the covers in addition. |
|
1008 Copying with changes limited to the covers, as long as they preserve |
|
1009 the title of the Document and satisfy these conditions, can be treated |
|
1010 as verbatim copying in other respects. |
|
1011 |
|
1012 If the required texts for either cover are too voluminous to fit |
|
1013 legibly, you should put the first ones listed (as many as fit |
|
1014 reasonably) on the actual cover, and continue the rest onto adjacent |
|
1015 pages. |
|
1016 |
|
1017 If you publish or distribute Opaque copies of the Document numbering |
|
1018 more than 100, you must either include a machine-readable Transparent |
|
1019 copy along with each Opaque copy, or state in or with each Opaque copy |
|
1020 a computer-network location from which the general network-using |
|
1021 public has access to download using public-standard network protocols |
|
1022 a complete Transparent copy of the Document, free of added material. |
|
1023 If you use the latter option, you must take reasonably prudent steps, |
|
1024 when you begin distribution of Opaque copies in quantity, to ensure |
|
1025 that this Transparent copy will remain thus accessible at the stated |
|
1026 location until at least one year after the last time you distribute an |
|
1027 Opaque copy (directly or through your agents or retailers) of that |
|
1028 edition to the public. |
|
1029 |
|
1030 It is requested, but not required, that you contact the authors of the |
|
1031 Document well before redistributing any large number of copies, to |
|
1032 give them a chance to provide you with an updated version of the |
|
1033 Document. |
|
1034 |
|
1035 |
|
1036 4. MODIFICATIONS |
|
1037 |
|
1038 You may copy and distribute a Modified Version of the Document under |
|
1039 the conditions of sections 2 and 3 above, provided that you release |
|
1040 the Modified Version under precisely this License, with the Modified |
|
1041 Version filling the role of the Document, thus licensing distribution |
|
1042 and modification of the Modified Version to whoever possesses a copy |
|
1043 of it. In addition, you must do these things in the Modified Version: |
|
1044 |
|
1045 A. Use in the Title Page (and on the covers, if any) a title distinct |
|
1046 from that of the Document, and from those of previous versions |
|
1047 (which should, if there were any, be listed in the History section |
|
1048 of the Document). You may use the same title as a previous version |
|
1049 if the original publisher of that version gives permission. |
|
1050 B. List on the Title Page, as authors, one or more persons or entities |
|
1051 responsible for authorship of the modifications in the Modified |
|
1052 Version, together with at least five of the principal authors of the |
|
1053 Document (all of its principal authors, if it has fewer than five), |
|
1054 unless they release you from this requirement. |
|
1055 C. State on the Title page the name of the publisher of the |
|
1056 Modified Version, as the publisher. |
|
1057 D. Preserve all the copyright notices of the Document. |
|
1058 E. Add an appropriate copyright notice for your modifications |
|
1059 adjacent to the other copyright notices. |
|
1060 F. Include, immediately after the copyright notices, a license notice |
|
1061 giving the public permission to use the Modified Version under the |
|
1062 terms of this License, in the form shown in the Addendum below. |
|
1063 G. Preserve in that license notice the full lists of Invariant Sections |
|
1064 and required Cover Texts given in the Document's license notice. |
|
1065 H. Include an unaltered copy of this License. |
|
1066 I. Preserve the section Entitled "History", Preserve its Title, and add |
|
1067 to it an item stating at least the title, year, new authors, and |
|
1068 publisher of the Modified Version as given on the Title Page. If |
|
1069 there is no section Entitled "History" in the Document, create one |
|
1070 stating the title, year, authors, and publisher of the Document as |
|
1071 given on its Title Page, then add an item describing the Modified |
|
1072 Version as stated in the previous sentence. |
|
1073 J. Preserve the network location, if any, given in the Document for |
|
1074 public access to a Transparent copy of the Document, and likewise |
|
1075 the network locations given in the Document for previous versions |
|
1076 it was based on. These may be placed in the "History" section. |
|
1077 You may omit a network location for a work that was published at |
|
1078 least four years before the Document itself, or if the original |
|
1079 publisher of the version it refers to gives permission. |
|
1080 K. For any section Entitled "Acknowledgements" or "Dedications", |
|
1081 Preserve the Title of the section, and preserve in the section all |
|
1082 the substance and tone of each of the contributor acknowledgements |
|
1083 and/or dedications given therein. |
|
1084 L. Preserve all the Invariant Sections of the Document, |
|
1085 unaltered in their text and in their titles. Section numbers |
|
1086 or the equivalent are not considered part of the section titles. |
|
1087 M. Delete any section Entitled "Endorsements". Such a section |
|
1088 may not be included in the Modified Version. |
|
1089 N. Do not retitle any existing section to be Entitled "Endorsements" |
|
1090 or to conflict in title with any Invariant Section. |
|
1091 O. Preserve any Warranty Disclaimers. |
|
1092 |
|
1093 If the Modified Version includes new front-matter sections or |
|
1094 appendices that qualify as Secondary Sections and contain no material |
|
1095 copied from the Document, you may at your option designate some or all |
|
1096 of these sections as invariant. To do this, add their titles to the |
|
1097 list of Invariant Sections in the Modified Version's license notice. |
|
1098 These titles must be distinct from any other section titles. |
|
1099 |
|
1100 You may add a section Entitled "Endorsements", provided it contains |
|
1101 nothing but endorsements of your Modified Version by various |
|
1102 parties--for example, statements of peer review or that the text has |
|
1103 been approved by an organization as the authoritative definition of a |
|
1104 standard. |
|
1105 |
|
1106 You may add a passage of up to five words as a Front-Cover Text, and a |
|
1107 passage of up to 25 words as a Back-Cover Text, to the end of the list |
|
1108 of Cover Texts in the Modified Version. Only one passage of |
|
1109 Front-Cover Text and one of Back-Cover Text may be added by (or |
|
1110 through arrangements made by) any one entity. If the Document already |
|
1111 includes a cover text for the same cover, previously added by you or |
|
1112 by arrangement made by the same entity you are acting on behalf of, |
|
1113 you may not add another; but you may replace the old one, on explicit |
|
1114 permission from the previous publisher that added the old one. |
|
1115 |
|
1116 The author(s) and publisher(s) of the Document do not by this License |
|
1117 give permission to use their names for publicity for or to assert or |
|
1118 imply endorsement of any Modified Version. |
|
1119 |
|
1120 |
|
1121 5. COMBINING DOCUMENTS |
|
1122 |
|
1123 You may combine the Document with other documents released under this |
|
1124 License, under the terms defined in section 4 above for modified |
|
1125 versions, provided that you include in the combination all of the |
|
1126 Invariant Sections of all of the original documents, unmodified, and |
|
1127 list them all as Invariant Sections of your combined work in its |
|
1128 license notice, and that you preserve all their Warranty Disclaimers. |
|
1129 |
|
1130 The combined work need only contain one copy of this License, and |
|
1131 multiple identical Invariant Sections may be replaced with a single |
|
1132 copy. If there are multiple Invariant Sections with the same name but |
|
1133 different contents, make the title of each such section unique by |
|
1134 adding at the end of it, in parentheses, the name of the original |
|
1135 author or publisher of that section if known, or else a unique number. |
|
1136 Make the same adjustment to the section titles in the list of |
|
1137 Invariant Sections in the license notice of the combined work. |
|
1138 |
|
1139 In the combination, you must combine any sections Entitled "History" |
|
1140 in the various original documents, forming one section Entitled |
|
1141 "History"; likewise combine any sections Entitled "Acknowledgements", |
|
1142 and any sections Entitled "Dedications". You must delete all sections |
|
1143 Entitled "Endorsements". |
|
1144 |
|
1145 |
|
1146 6. COLLECTIONS OF DOCUMENTS |
|
1147 |
|
1148 You may make a collection consisting of the Document and other |
|
1149 documents released under this License, and replace the individual |
|
1150 copies of this License in the various documents with a single copy |
|
1151 that is included in the collection, provided that you follow the rules |
|
1152 of this License for verbatim copying of each of the documents in all |
|
1153 other respects. |
|
1154 |
|
1155 You may extract a single document from such a collection, and |
|
1156 distribute it individually under this License, provided you insert a |
|
1157 copy of this License into the extracted document, and follow this |
|
1158 License in all other respects regarding verbatim copying of that |
|
1159 document. |
|
1160 |
|
1161 |
|
1162 7. AGGREGATION WITH INDEPENDENT WORKS |
|
1163 |
|
1164 A compilation of the Document or its derivatives with other separate |
|
1165 and independent documents or works, in or on a volume of a storage or |
|
1166 distribution medium, is called an "aggregate" if the copyright |
|
1167 resulting from the compilation is not used to limit the legal rights |
|
1168 of the compilation's users beyond what the individual works permit. |
|
1169 When the Document is included in an aggregate, this License does not |
|
1170 apply to the other works in the aggregate which are not themselves |
|
1171 derivative works of the Document. |
|
1172 |
|
1173 If the Cover Text requirement of section 3 is applicable to these |
|
1174 copies of the Document, then if the Document is less than one half of |
|
1175 the entire aggregate, the Document's Cover Texts may be placed on |
|
1176 covers that bracket the Document within the aggregate, or the |
|
1177 electronic equivalent of covers if the Document is in electronic form. |
|
1178 Otherwise they must appear on printed covers that bracket the whole |
|
1179 aggregate. |
|
1180 |
|
1181 |
|
1182 8. TRANSLATION |
|
1183 |
|
1184 Translation is considered a kind of modification, so you may |
|
1185 distribute translations of the Document under the terms of section 4. |
|
1186 Replacing Invariant Sections with translations requires special |
|
1187 permission from their copyright holders, but you may include |
|
1188 translations of some or all Invariant Sections in addition to the |
|
1189 original versions of these Invariant Sections. You may include a |
|
1190 translation of this License, and all the license notices in the |
|
1191 Document, and any Warranty Disclaimers, provided that you also include |
|
1192 the original English version of this License and the original versions |
|
1193 of those notices and disclaimers. In case of a disagreement between |
|
1194 the translation and the original version of this License or a notice |
|
1195 or disclaimer, the original version will prevail. |
|
1196 |
|
1197 If a section in the Document is Entitled "Acknowledgements", |
|
1198 "Dedications", or "History", the requirement (section 4) to Preserve |
|
1199 its Title (section 1) will typically require changing the actual |
|
1200 title. |
|
1201 |
|
1202 |
|
1203 9. TERMINATION |
|
1204 |
|
1205 You may not copy, modify, sublicense, or distribute the Document |
|
1206 except as expressly provided under this License. Any attempt |
|
1207 otherwise to copy, modify, sublicense, or distribute it is void, and |
|
1208 will automatically terminate your rights under this License. |
|
1209 |
|
1210 However, if you cease all violation of this License, then your license |
|
1211 from a particular copyright holder is reinstated (a) provisionally, |
|
1212 unless and until the copyright holder explicitly and finally |
|
1213 terminates your license, and (b) permanently, if the copyright holder |
|
1214 fails to notify you of the violation by some reasonable means prior to |
|
1215 60 days after the cessation. |
|
1216 |
|
1217 Moreover, your license from a particular copyright holder is |
|
1218 reinstated permanently if the copyright holder notifies you of the |
|
1219 violation by some reasonable means, this is the first time you have |
|
1220 received notice of violation of this License (for any work) from that |
|
1221 copyright holder, and you cure the violation prior to 30 days after |
|
1222 your receipt of the notice. |
|
1223 |
|
1224 Termination of your rights under this section does not terminate the |
|
1225 licenses of parties who have received copies or rights from you under |
|
1226 this License. If your rights have been terminated and not permanently |
|
1227 reinstated, receipt of a copy of some or all of the same material does |
|
1228 not give you any rights to use it. |
|
1229 |
|
1230 |
|
1231 10. FUTURE REVISIONS OF THIS LICENSE |
|
1232 |
|
1233 The Free Software Foundation may publish new, revised versions of the |
|
1234 GNU Free Documentation License from time to time. Such new versions |
|
1235 will be similar in spirit to the present version, but may differ in |
|
1236 detail to address new problems or concerns. See |
|
1237 http://www.gnu.org/copyleft/. |
|
1238 |
|
1239 Each version of the License is given a distinguishing version number. |
|
1240 If the Document specifies that a particular numbered version of this |
|
1241 License "or any later version" applies to it, you have the option of |
|
1242 following the terms and conditions either of that specified version or |
|
1243 of any later version that has been published (not as a draft) by the |
|
1244 Free Software Foundation. If the Document does not specify a version |
|
1245 number of this License, you may choose any version ever published (not |
|
1246 as a draft) by the Free Software Foundation. If the Document |
|
1247 specifies that a proxy can decide which future versions of this |
|
1248 License can be used, that proxy's public statement of acceptance of a |
|
1249 version permanently authorizes you to choose that version for the |
|
1250 Document. |
|
1251 |
|
1252 11. RELICENSING |
|
1253 |
|
1254 "Massive Multiauthor Collaboration Site" (or "MMC Site") means any |
|
1255 World Wide Web server that publishes copyrightable works and also |
|
1256 provides prominent facilities for anybody to edit those works. A |
|
1257 public wiki that anybody can edit is an example of such a server. A |
|
1258 "Massive Multiauthor Collaboration" (or "MMC") contained in the site |
|
1259 means any set of copyrightable works thus published on the MMC site. |
755 |
1260 |
756 "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 |
1261 "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 |
