PREAMBLE 13*4882a593Smuzhiyun 14*4882a593SmuzhiyunThe purpose of this License is to make a manual, textbook, or other 15*4882a593Smuzhiyunfunctional and useful document "free" in the sense of freedom: to 16*4882a593Smuzhiyunassure everyone the effective freedom to copy and redistribute it, 17*4882a593Smuzhiyunwith or without modifying it, either commercially or noncommercially. 18*4882a593SmuzhiyunSecondarily, this License preserves for the author and publisher a way 19*4882a593Smuzhiyunto get credit for their work, while not being considered responsible 20*4882a593Smuzhiyunfor modifications made by others. 21*4882a593Smuzhiyun 22*4882a593SmuzhiyunThis License is a kind of "copyleft", which means that derivative 23*4882a593Smuzhiyunworks of the document must themselves be free in the same sense. It 24*4882a593Smuzhiyuncomplements the GNU General Public License, which is a copyleft 25*4882a593Smuzhiyunlicense designed for free software. 26*4882a593Smuzhiyun 27*4882a593SmuzhiyunWe have designed this License in order to use it for manuals for free 28*4882a593Smuzhiyunsoftware, because free software needs free documentation: a free 29*4882a593Smuzhiyunprogram should come with manuals providing the same freedoms that the 30*4882a593Smuzhiyunsoftware does. But this License is not limited to software manuals; 31*4882a593Smuzhiyunit can be used for any textual work, regardless of subject matter or 32*4882a593Smuzhiyunwhether it is published as a printed book. We recommend this License 33*4882a593Smuzhiyunprincipally for works whose purpose is instruction or reference. 34*4882a593Smuzhiyun 35*4882a593Smuzhiyun 36*4882a593Smuzhiyun1. APPLICABILITY AND DEFINITIONS 37*4882a593Smuzhiyun 38*4882a593SmuzhiyunThis License applies to any manual or other work, in any medium, that 39*4882a593Smuzhiyuncontains a notice placed by the copyright holder saying it can be 40*4882a593Smuzhiyundistributed under the terms of this License. Such a notice grants a 41*4882a593Smuzhiyunworld-wide, royalty-free license, unlimited in duration, to use that 42*4882a593Smuzhiyunwork under the conditions stated herein. The "Document", below, 43*4882a593Smuzhiyunrefers to any such manual or work. Any member of the public is a 44*4882a593Smuzhiyunlicensee, and is addressed as "you". You accept the license if you 45*4882a593Smuzhiyuncopy, modify or distribute the work in a way requiring permission 46*4882a593Smuzhiyununder copyright law. 47*4882a593Smuzhiyun 48*4882a593SmuzhiyunA "Modified Version" of the Document means any work containing the 49*4882a593SmuzhiyunDocument or a portion of it, either copied verbatim, or with 50*4882a593Smuzhiyunmodifications and/or translated into another language. 51*4882a593Smuzhiyun 52*4882a593SmuzhiyunA "Secondary Section" is a named appendix or a front-matter section of 53*4882a593Smuzhiyunthe Document that deals exclusively with the relationship of the 54*4882a593Smuzhiyunpublishers or authors of the Document to the Document`s overall 55*4882a593Smuzhiyunsubject (or to related matters) and contains nothing that could fall 56*4882a593Smuzhiyundirectly within that overall subject. (Thus, if the Document is in 57*4882a593Smuzhiyunpart a textbook of mathematics, a Secondary Section may not explain 58*4882a593Smuzhiyunany mathematics.) The relationship could be a matter of historical 59*4882a593Smuzhiyunconnection with the subject or with related matters, or of legal, 60*4882a593Smuzhiyuncommercial, philosophical, ethical or political position regarding 61*4882a593Smuzhiyunthem. 62*4882a593Smuzhiyun 63*4882a593SmuzhiyunThe "Invariant Sections" are certain Secondary Sections whose titles 64*4882a593Smuzhiyunare designated, as being those of Invariant Sections, in the notice 65*4882a593Smuzhiyunthat says that the Document is released under this License. If a 66*4882a593Smuzhiyunsection does not fit the above definition of Secondary then it is not 67*4882a593Smuzhiyunallowed to be designated as Invariant. The Document may contain zero 68*4882a593SmuzhiyunInvariant Sections. If the Document does not identify any Invariant 69*4882a593SmuzhiyunSections then there are none. 70*4882a593Smuzhiyun 71*4882a593SmuzhiyunThe "Cover Texts" are certain short passages of text that are listed, 72*4882a593Smuzhiyunas Front-Cover Texts or Back-Cover Texts, in the notice that says that 73*4882a593Smuzhiyunthe Document is released under this License. A Front-Cover Text may 74*4882a593Smuzhiyunbe at most 5 words, and a Back-Cover Text may be at most 25 words. 75*4882a593Smuzhiyun 76*4882a593SmuzhiyunA "Transparent" copy of the Document means a machine-readable copy, 77*4882a593Smuzhiyunrepresented in a format whose specification is available to the 78*4882a593Smuzhiyungeneral public, that is suitable for revising the document 79*4882a593Smuzhiyunstraightforwardly with generic text editors or (for images composed of 80*4882a593Smuzhiyunpixels) generic paint programs or (for drawings) some widely available 81*4882a593Smuzhiyundrawing editor, and that is suitable for input to text formatters or 82*4882a593Smuzhiyunfor automatic translation to a variety of formats suitable for input 83*4882a593Smuzhiyunto text formatters. A copy made in an otherwise Transparent file 84*4882a593Smuzhiyunformat whose markup, or absence of markup, has been arranged to thwart 85*4882a593Smuzhiyunor discourage subsequent modification by readers is not Transparent. 86*4882a593SmuzhiyunAn image format is not Transparent if used for any substantial amount 87*4882a593Smuzhiyunof text. A copy that is not "Transparent" is called "Opaque". 88*4882a593Smuzhiyun 89*4882a593SmuzhiyunExamples of suitable formats for Transparent copies include plain 90*4882a593SmuzhiyunASCII without markup, Texinfo input format, LaTeX input format, SGML 91*4882a593Smuzhiyunor XML using a publicly available DTD, and standard-conforming simple 92*4882a593SmuzhiyunHTML, PostScript or PDF designed for human modification. Examples of 93*4882a593Smuzhiyuntransparent image formats include PNG, XCF and JPG. Opaque formats 94*4882a593Smuzhiyuninclude proprietary formats that can be read and edited only by 95*4882a593Smuzhiyunproprietary word processors, SGML or XML for which the DTD and/or 96*4882a593Smuzhiyunprocessing tools are not generally available, and the 97*4882a593Smuzhiyunmachine-generated HTML, PostScript or PDF produced by some word 98*4882a593Smuzhiyunprocessors for output purposes only. 99*4882a593Smuzhiyun 100*4882a593SmuzhiyunThe "Title Page" means, for a printed book, the title page itself, 101*4882a593Smuzhiyunplus such following pages as are needed to hold, legibly, the material 102*4882a593Smuzhiyunthis License requires to appear in the title page. For works in 103*4882a593Smuzhiyunformats which do not have any title page as such, "Title Page" means 104*4882a593Smuzhiyunthe text near the most prominent appearance of the work`s title, 105*4882a593Smuzhiyunpreceding the beginning of the body of the text. 106*4882a593Smuzhiyun 107*4882a593SmuzhiyunThe "publisher" means any person or entity that distributes copies of 108*4882a593Smuzhiyunthe Document to the public. 109*4882a593Smuzhiyun 110*4882a593SmuzhiyunA section "Entitled XYZ" means a named subunit of the Document whose 111*4882a593Smuzhiyuntitle either is precisely XYZ or contains XYZ in parentheses following 112*4882a593Smuzhiyuntext that translates XYZ in another language. (Here XYZ stands for a 113*4882a593Smuzhiyunspecific section name mentioned below, such as "Acknowledgements", 114*4882a593Smuzhiyun"Dedications", "Endorsements", or "History".) To "Preserve the Title" 115*4882a593Smuzhiyunof such a section when you modify the Document means that it remains a 116*4882a593Smuzhiyunsection "Entitled XYZ" according to this definition. 117*4882a593Smuzhiyun 118*4882a593SmuzhiyunThe Document may include Warranty Disclaimers next to the notice which 119*4882a593Smuzhiyunstates that this License applies to the Document. These Warranty 120*4882a593SmuzhiyunDisclaimers are considered to be included by reference in this 121*4882a593SmuzhiyunLicense, but only as regards disclaiming warranties: any other 122*4882a593Smuzhiyunimplication that these Warranty Disclaimers may have is void and has 123*4882a593Smuzhiyunno effect on the meaning of this License. 124*4882a593Smuzhiyun 125*4882a593Smuzhiyun2. VERBATIM COPYING 126*4882a593Smuzhiyun 127*4882a593SmuzhiyunYou may copy and distribute the Document in any medium, either 128*4882a593Smuzhiyuncommercially or noncommercially, provided that this License, the 129*4882a593Smuzhiyuncopyright notices, and the license notice saying this License applies 130*4882a593Smuzhiyunto the Document are reproduced in all copies, and that you add no 131*4882a593Smuzhiyunother conditions whatsoever to those of this License. You may not use 132*4882a593Smuzhiyuntechnical measures to obstruct or control the reading or further 133*4882a593Smuzhiyuncopying of the copies you make or distribute. However, you may accept 134*4882a593Smuzhiyuncompensation in exchange for copies. If you distribute a large enough 135*4882a593Smuzhiyunnumber of copies you must also follow the conditions in section 3. 136*4882a593Smuzhiyun 137*4882a593SmuzhiyunYou may also lend copies, under the same conditions stated above, and 138*4882a593Smuzhiyunyou may publicly display copies. 139*4882a593Smuzhiyun 140*4882a593Smuzhiyun 141*4882a593Smuzhiyun3. COPYING IN QUANTITY 142*4882a593Smuzhiyun 143*4882a593SmuzhiyunIf you publish printed copies (or copies in media that commonly have 144*4882a593Smuzhiyunprinted covers) of the Document, numbering more than 100, and the 145*4882a593SmuzhiyunDocument`s license notice requires Cover Texts, you must enclose the 146*4882a593Smuzhiyuncopies in covers that carry, clearly and legibly, all these Cover 147*4882a593SmuzhiyunTexts: Front-Cover Texts on the front cover, and Back-Cover Texts on 148*4882a593Smuzhiyunthe back cover. Both covers must also clearly and legibly identify 149*4882a593Smuzhiyunyou as the publisher of these copies. The front cover must present 150*4882a593Smuzhiyunthe full title with all words of the title equally prominent and 151*4882a593Smuzhiyunvisible. You may add other material on the covers in addition. 152*4882a593SmuzhiyunCopying with changes limited to the covers, as long as they preserve 153*4882a593Smuzhiyunthe title of the Document and satisfy these conditions, can be treated 154*4882a593Smuzhiyunas verbatim copying in other respects. 155*4882a593Smuzhiyun 156*4882a593SmuzhiyunIf the required texts for either cover are too voluminous to fit 157*4882a593Smuzhiyunlegibly, you should put the first ones listed (as many as fit 158*4882a593Smuzhiyunreasonably) on the actual cover, and continue the rest onto adjacent 159*4882a593Smuzhiyunpages. 160*4882a593Smuzhiyun 161*4882a593SmuzhiyunIf you publish or distribute Opaque copies of the Document numbering 162*4882a593Smuzhiyunmore than 100, you must either include a machine-readable Transparent 163*4882a593Smuzhiyuncopy along with each Opaque copy, or state in or with each Opaque copy 164*4882a593Smuzhiyuna computer-network location from which the general network-using 165*4882a593Smuzhiyunpublic has access to download using public-standard network protocols 166*4882a593Smuzhiyuna complete Transparent copy of the Document, free of added material. 167*4882a593SmuzhiyunIf you use the latter option, you must take reasonably prudent steps, 168*4882a593Smuzhiyunwhen you begin distribution of Opaque copies in quantity, to ensure 169*4882a593Smuzhiyunthat this Transparent copy will remain thus accessible at the stated 170*4882a593Smuzhiyunlocation until at least one year after the last time you distribute an 171*4882a593SmuzhiyunOpaque copy (directly or through your agents or retailers) of that 172*4882a593Smuzhiyunedition to the public. 173*4882a593Smuzhiyun 174*4882a593SmuzhiyunIt is requested, but not required, that you contact the authors of the 175*4882a593SmuzhiyunDocument well before redistributing any large number of copies, to 176*4882a593Smuzhiyungive them a chance to provide you with an updated version of the 177*4882a593SmuzhiyunDocument. 178*4882a593Smuzhiyun 179*4882a593Smuzhiyun 180*4882a593Smuzhiyun4.
