Such a notice grants a 47136644Sacheworld-wide, royalty-free license, unlimited in duration, to use that 48136644Sachework under the conditions stated herein. The ``Document'', below, 49136644Sacherefers to any such manual or work. Any member of the public is a 50136644Sachelicensee, and is addressed as ``you''. You accept the license if you 51136644Sachecopy, modify or distribute the work in a way requiring permission 52136644Sacheunder copyright law. 53136644Sache 54136644SacheA ``Modified Version'' of the Document means any work containing the 55136644SacheDocument or a portion of it, either copied verbatim, or with 56136644Sachemodifications and/or translated into another language. 57136644Sache 58136644SacheA ``Secondary Section'' is a named appendix or a front-matter section 59136644Sacheof the Document that deals exclusively with the relationship of the 60136644Sachepublishers or authors of the Document to the Document's overall 61136644Sachesubject (or to related matters) and contains nothing that could fall 62136644Sachedirectly within that overall subject. (Thus, if the Document is in 63136644Sachepart a textbook of mathematics, a Secondary Section may not explain 64136644Sacheany mathematics.) The relationship could be a matter of historical 65136644Sacheconnection with the subject or with related matters, or of legal, 66136644Sachecommercial, philosophical, ethical or political position regarding 67136644Sachethem. 68136644Sache 69136644SacheThe ``Invariant Sections'' are certain Secondary Sections whose titles 70136644Sacheare designated, as being those of Invariant Sections, in the notice 71136644Sachethat says that the Document is released under this License. If a 72136644Sachesection does not fit the above definition of Secondary then it is not 73136644Sacheallowed to be designated as Invariant. The Document may contain zero 74136644SacheInvariant Sections. If the Document does not identify any Invariant 75136644SacheSections then there are none. 76136644Sache 77136644SacheThe ``Cover Texts'' are certain short passages of text that are listed, 78136644Sacheas Front-Cover Texts or Back-Cover Texts, in the notice that says that 79136644Sachethe Document is released under this License. A Front-Cover Text may 80136644Sachebe at most 5 words, and a Back-Cover Text may be at most 25 words. 81136644Sache 82136644SacheA ``Transparent'' copy of the Document means a machine-readable copy, 83136644Sacherepresented in a format whose specification is available to the 84136644Sachegeneral public, that is suitable for revising the document 85136644Sachestraightforwardly with generic text editors or (for images composed of 86136644Sachepixels) generic paint programs or (for drawings) some widely available 87136644Sachedrawing editor, and that is suitable for input to text formatters or 88136644Sachefor automatic translation to a variety of formats suitable for input 89136644Sacheto text formatters. A copy made in an otherwise Transparent file 90136644Sacheformat whose markup, or absence of markup, has been arranged to thwart 91136644Sacheor discourage subsequent modification by readers is not Transparent. 92136644SacheAn image format is not Transparent if used for any substantial amount 93136644Sacheof text. A copy that is not ``Transparent'' is called ``Opaque''. 94136644Sache 95136644SacheExamples of suitable formats for Transparent copies include plain 96136644Sache@sc{ascii} without markup, Texinfo input format, La@TeX{} input 97136644Sacheformat, @acronym{SGML} or @acronym{XML} using a publicly available 98136644Sache@acronym{DTD}, and standard-conforming simple @acronym{HTML}, 99136644SachePostScript or @acronym{PDF} designed for human modification. Examples 100136644Sacheof transparent image formats include @acronym{PNG}, @acronym{XCF} and 101136644Sache@acronym{JPG}. Opaque formats include proprietary formats that can be 102136644Sacheread and edited only by proprietary word processors, @acronym{SGML} or 103136644Sache@acronym{XML} for which the @acronym{DTD} and/or processing tools are 104136644Sachenot generally available, and the machine-generated @acronym{HTML}, 105136644SachePostScript or @acronym{PDF} produced by some word processors for 106136644Sacheoutput purposes only. 107136644Sache 108136644SacheThe ``Title Page'' means, for a printed book, the title page itself, 109136644Sacheplus such following pages as are needed to hold, legibly, the material 110136644Sachethis License requires to appear in the title page. For works in 111136644Sacheformats which do not have any title page as such, ``Title Page'' means 112136644Sachethe text near the most prominent appearance of the work's title, 113136644Sachepreceding the beginning of the body of the text. 114136644Sache 115136644SacheA section ``Entitled XYZ'' means a named subunit of the Document whose 116136644Sachetitle either is precisely XYZ or contains XYZ in parentheses following 117136644Sachetext that translates XYZ in another language. (Here XYZ stands for a 118136644Sachespecific section name mentioned below, such as ``Acknowledgements'', 119136644Sache``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' 120136644Sacheof such a section when you modify the Document means that it remains a 121136644Sachesection ``Entitled XYZ'' according to this definition. 122136644Sache 123136644SacheThe Document may include Warranty Disclaimers next to the notice which 124136644Sachestates that this License applies to the Document. These Warranty 125136644SacheDisclaimers are considered to be included by reference in this 126136644SacheLicense, but only as regards disclaiming warranties: any other 127136644Sacheimplication that these Warranty Disclaimers may have is void and has 128136644Sacheno effect on the meaning of this License. 129136644Sache 130136644Sache@item 131136644SacheVERBATIM COPYING 132136644Sache 133136644SacheYou may copy and distribute the Document in any medium, either 134136644Sachecommercially or noncommercially, provided that this License, the 135136644Sachecopyright notices, and the license notice saying this License applies 136136644Sacheto the Document are reproduced in all copies, and that you add no other 137136644Sacheconditions whatsoever to those of this License.
