                     34: software, because free software needs free documentation: a free
                     35: program should come with manuals providing the same freedoms that the

                     38: whether it is published as a printed book.  We recommend this License

                     43: 
1.2     ! pazsan     44: This License applies to any manual or other work, in any medium, that
        !            45: contains a notice placed by the copyright holder saying it can be
        !            46: distributed under the terms of this License.  Such a notice grants a
        !            47: world-wide, royalty-free license, unlimited in duration, to use that
        !            48: work under the conditions stated herein.  The ``Document'', below,
        !            49: refers to any such manual or work.  Any member of the public is a
        !            50: licensee, and is addressed as ``you''.  You accept the license if you
        !            51: copy, modify or distribute the work in a way requiring permission
        !            52: under copyright law.
1.1       anton      53: 
                     54: A ``Modified Version'' of the Document means any work containing the
                     55: Document or a portion of it, either copied verbatim, or with
                     56: modifications and/or translated into another language.
                     57: 
1.2     ! pazsan     58: A ``Secondary Section'' is a named appendix or a front-matter section
        !            59: of the Document that deals exclusively with the relationship of the
        !            60: publishers or authors of the Document to the Document's overall
        !            61: subject (or to related matters) and contains nothing that could fall
        !            62: directly within that overall subject.  (Thus, if the Document is in
        !            63: part a textbook of mathematics, a Secondary Section may not explain
        !            64: any mathematics.)  The relationship could be a matter of historical
1.1       anton      65: connection with the subject or with related matters, or of legal,
                     66: commercial, philosophical, ethical or political position regarding
                     67: them.
                     68: 
                     69: The ``Invariant Sections'' are certain Secondary Sections whose titles
                     70: are designated, as being those of Invariant Sections, in the notice
1.2     ! pazsan     71: that says that the Document is released under this License.  If a
        !            72: section does not fit the above definition of Secondary then it is not
        !            73: allowed to be designated as Invariant.  The Document may contain zero
        !            74: Invariant Sections.  If the Document does not identify any Invariant
        !            75: Sections then there are none.
1.1       anton      76: 
                     77: The ``Cover Texts'' are certain short passages of text that are listed,
                     78: as Front-Cover Texts or Back-Cover Texts, in the notice that says that
1.2     ! pazsan     79: the Document is released under this License.  A Front-Cover Text may
        !            80: be at most 5 words, and a Back-Cover Text may be at most 25 words.
1.1       anton      81: 
                     82: A ``Transparent'' copy of the Document means a machine-readable copy,
                     83: represented in a format whose specification is available to the
1.2     ! pazsan     84: general public, that is suitable for revising the document
1.1       anton      85: straightforwardly with generic text editors or (for images composed of
                     86: pixels) generic paint programs or (for drawings) some widely available
                     87: drawing editor, and that is suitable for input to text formatters or
                     88: for automatic translation to a variety of formats suitable for input
                     89: to text formatters.  A copy made in an otherwise Transparent file
1.2     ! pazsan     90: format whose markup, or absence of markup, has been arranged to thwart
        !            91: or discourage subsequent modification by readers is not Transparent.
        !            92: An image format is not Transparent if used for any substantial amount
        !            93: of text.  A copy that is not ``Transparent'' is called ``Opaque''.
1.1       anton      94: 
                     95: Examples of suitable formats for Transparent copies include plain
1.2     ! pazsan     96: @sc{ascii} without markup, Texinfo input format, La@TeX{} input
        !            97: format, @acronym{SGML} or @acronym{XML} using a publicly available
        !            98: @acronym{DTD}, and standard-conforming simple @acronym{HTML},
        !            99: PostScript or @acronym{PDF} designed for human modification.  Examples
        !           100: of transparent image formats include @acronym{PNG}, @acronym{XCF} and
        !           101: @acronym{JPG}.  Opaque formats include proprietary formats that can be
        !           102: read and edited only by proprietary word processors, @acronym{SGML} or
        !           103: @acronym{XML} for which the @acronym{DTD} and/or processing tools are
        !           104: not generally available, and the machine-generated @acronym{HTML},
        !           105: PostScript or @acronym{PDF} produced by some word processors for
        !           106: output purposes only.
1.1       anton     107: 
                    108: The ``Title Page'' means, for a printed book, the title page itself,
                    109: plus such following pages as are needed to hold, legibly, the material
                    110: this License requires to appear in the title page.  For works in
                    111: formats which do not have any title page as such, ``Title Page'' means
                    112: the text near the most prominent appearance of the work's title,
                    113: preceding the beginning of the body of the text.
                    114: 
1.2     ! pazsan    115: A section ``Entitled XYZ'' means a named subunit of the Document whose
        !           116: title either is precisely XYZ or contains XYZ in parentheses following
        !           117: text that translates XYZ in another language.  (Here XYZ stands for a
        !           118: specific section name mentioned below, such as ``Acknowledgements'',
        !           119: ``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
        !           120: of such a section when you modify the Document means that it remains a

        !           122: 
        !           123: The Document may include Warranty Disclaimers next to the notice which
        !           124: states that this License applies to the Document.  These Warranty
        !           125: Disclaimers are considered to be included by reference in this
        !           126: License, but only as regards disclaiming warranties: any other
        !           127: implication that these Warranty Disclaimers may have is void and has
        !           128: no effect on the meaning of this License.

                    163: legibly, you should put the first ones listed (as many as fit
                    164: reasonably) on the actual cover, and continue the rest onto adjacent
