1.2       pazsan     17: functional and useful document @dfn{free} in the sense of freedom: to
                     18: assure everyone the effective freedom to copy and redistribute it,
                     19: with or without modifying it, either commercially or noncommercially.

                     24: This License is a kind of ``copyleft'', which means that derivative
                     25: works of the document must themselves be free in the same sense.  It
                     26: complements the GNU General Public License, which is a copyleft
                     27: license designed for free software.
                     29: We have designed this License in order to use it for manuals for free
                     30: software, because free software needs free documentation: a free
                     31: program should come with manuals providing the same freedoms that the

                     33: it can be used for any textual work, regardless of subject matter or
                     34: whether it is published as a printed book.  We recommend this License
                     35: principally for works whose purpose is instruction or reference.

                     38: APPLICABILITY AND DEFINITIONS
1.2       pazsan     40: This License applies to any manual or other work, in any medium, that
                     41: contains a notice placed by the copyright holder saying it can be
                     42: distributed under the terms of this License.  Such a notice grants a
                     43: world-wide, royalty-free license, unlimited in duration, to use that
                     44: work under the conditions stated herein.  The ``Document'', below,
                     45: refers to any such manual or work.  Any member of the public is a
                     46: licensee, and is addressed as ``you''.  You accept the license if you
                     47: copy, modify or distribute the work in a way requiring permission
                     48: under copyright law.
1.1       anton      49: 
                     50: A ``Modified Version'' of the Document means any work containing the
                     51: Document or a portion of it, either copied verbatim, or with
                     52: modifications and/or translated into another language.
1.2       pazsan     54: A ``Secondary Section'' is a named appendix or a front-matter section
                     55: of the Document that deals exclusively with the relationship of the
                     56: publishers or authors of the Document to the Document's overall
                     57: subject (or to related matters) and contains nothing that could fall
                     58: directly within that overall subject.  (Thus, if the Document is in
                     59: part a textbook of mathematics, a Secondary Section may not explain
                     60: any mathematics.)  The relationship could be a matter of historical
1.1       anton      61: connection with the subject or with related matters, or of legal,
                     62: commercial, philosophical, ethical or political position regarding
                     63: them.
                     65: The ``Invariant Sections'' are certain Secondary Sections whose titles
                     66: are designated, as being those of Invariant Sections, in the notice
1.2       pazsan     67: that says that the Document is released under this License.  If a
                     68: section does not fit the above definition of Secondary then it is not
                     69: allowed to be designated as Invariant.  The Document may contain zero
                     70: Invariant Sections.  If the Document does not identify any Invariant
                     71: Sections then there are none.
1.1       anton      72: 
                     73: The ``Cover Texts'' are certain short passages of text that are listed,
                     74: as Front-Cover Texts or Back-Cover Texts, in the notice that says that
1.2       pazsan     75: the Document is released under this License.  A Front-Cover Text may
                     76: be at most 5 words, and a Back-Cover Text may be at most 25 words.
1.1       anton      77: 
                     78: A ``Transparent'' copy of the Document means a machine-readable copy,
                     79: represented in a format whose specification is available to the
1.2       pazsan     80: general public, that is suitable for revising the document
1.1       anton      81: straightforwardly with generic text editors or (for images composed of
                     82: pixels) generic paint programs or (for drawings) some widely available
                     83: drawing editor, and that is suitable for input to text formatters or
                     84: for automatic translation to a variety of formats suitable for input
                     85: to text formatters.  A copy made in an otherwise Transparent file
1.2       pazsan     86: format whose markup, or absence of markup, has been arranged to thwart
                     87: or discourage subsequent modification by readers is not Transparent.
                     88: An image format is not Transparent if used for any substantial amount
                     89: of text.  A copy that is not ``Transparent'' is called ``Opaque''.
1.1       anton      90: 
                     91: Examples of suitable formats for Transparent copies include plain
1.2       pazsan     92: @sc{ascii} without markup, Texinfo input format, La@TeX{} input
                     93: format, @acronym{SGML} or @acronym{XML} using a publicly available
                     94: @acronym{DTD}, and standard-conforming simple @acronym{HTML},
                     95: PostScript or @acronym{PDF} designed for human modification.  Examples
                     96: of transparent image formats include @acronym{PNG}, @acronym{XCF} and
                     97: @acronym{JPG}.  Opaque formats include proprietary formats that can be
                     98: read and edited only by proprietary word processors, @acronym{SGML} or
                     99: @acronym{XML} for which the @acronym{DTD} and/or processing tools are
                    100: not generally available, and the machine-generated @acronym{HTML},
                    101: PostScript or @acronym{PDF} produced by some word processors for
                    102: output purposes only.
1.1       anton     103: 
                    104: The ``Title Page'' means, for a printed book, the title page itself,
                    105: plus such following pages as are needed to hold, legibly, the material
                    106: this License requires to appear in the title page.  For works in
                    107: formats which do not have any title page as such, ``Title Page'' means
                    108: the text near the most prominent appearance of the work's title,
                    109: preceding the beginning of the body of the text.
1.2       pazsan    111: A section ``Entitled XYZ'' means a named subunit of the Document whose
                    112: title either is precisely XYZ or contains XYZ in parentheses following
                    113: text that translates XYZ in another language.  (Here XYZ stands for a
                    114: specific section name mentioned below, such as ``Acknowledgements'',
                    115: ``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
                    116: of such a section when you modify the Document means that it remains a
                    117: section ``Entitled XYZ'' according to this definition.
                    119: The Document may include Warranty Disclaimers next to the notice which
                    120: states that this License applies to the Document.  These Warranty
                    121: Disclaimers are considered to be included by reference in this
                    122: License, but only as regards disclaiming warranties: any other
                    123: implication that these Warranty Disclaimers may have is void and has
                    124: no effect on the meaning of this License.

                    143: COPYING IN QUANTITY
1.2       pazsan    145: If you publish printed copies (or copies in media that commonly have
                    146: printed covers) of the Document, numbering more than 100, and the
                    147: Document's license notice requires Cover Texts, you must enclose the

                    150: the back cover.  Both covers must also clearly and legibly identify
                    151: you as the publisher of these copies.  The front cover must present
                    152: the full title with all words of the title equally prominent and
                    153: visible.  You may add other material on the covers in addition.
                    154: Copying with changes limited to the covers, as long as they preserve
                    155: the title of the Document and satisfy these conditions, can be treated
                    156: as verbatim copying in other respects.
                    158: If the required texts for either cover are too voluminous to fit
                    159: legibly, you should put the first ones listed (as many as fit
                    160: reasonably) on the actual cover, and continue the rest onto adjacent
                    161: pages.

                    171: that this Transparent copy will remain thus accessible at the stated
