        !            21: written document @dfn{free} in the sense of freedom: to assure everyone
        !            22: the effective freedom to copy and redistribute it, with or without

        !            25: credit for their work, while not being considered responsible for

        !            27: 
        !            28: This License is a kind of ``copyleft'', which means that derivative
        !            29: works of the document must themselves be free in the same sense.  It
        !            30: complements the GNU General Public License, which is a copyleft
        !            31: license designed for free software.
        !            32: 
        !            33: We have designed this License in order to use it for manuals for free
        !            34: software, because free software needs free documentation: a free
        !            35: program should come with manuals providing the same freedoms that the
        !            36: software does.  But this License is not limited to software manuals;
        !            37: it can be used for any textual work, regardless of subject matter or
        !            38: whether it is published as a printed book.  We recommend this License
        !            39: principally for works whose purpose is instruction or reference.

        !            43: 
        !            44: This License applies to any manual or other work that contains a
        !            45: notice placed by the copyright holder saying it can be distributed
        !            46: under the terms of this License.  The ``Document'', below, refers to any
        !            47: such manual or work.  Any member of the public is a licensee, and is
        !            48: addressed as ``you''.
        !            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.
        !            53: 
        !            54: A ``Secondary Section'' is a named appendix or a front-matter section of
        !            55: the Document that deals exclusively with the relationship of the
        !            56: publishers or authors of the Document to the Document's overall subject
        !            57: (or to related matters) and contains nothing that could fall directly
        !            58: within that overall subject.  (For example, if the Document is in part a
        !            59: textbook of mathematics, a Secondary Section may not explain any
        !            60: mathematics.)  The relationship could be a matter of historical
        !            61: connection with the subject or with related matters, or of legal,
        !            62: commercial, philosophical, ethical or political position regarding
        !            63: them.
        !            64: 
        !            65: The ``Invariant Sections'' are certain Secondary Sections whose titles
        !            66: are designated, as being those of Invariant Sections, in the notice
        !            67: that says that the Document is released under this License.
        !            68: 
        !            69: The ``Cover Texts'' are certain short passages of text that are listed,
        !            70: as Front-Cover Texts or Back-Cover Texts, in the notice that says that
        !            71: the Document is released under this License.
        !            72: 
        !            73: A ``Transparent'' copy of the Document means a machine-readable copy,
        !            74: represented in a format whose specification is available to the
        !            75: general public, whose contents can be viewed and edited directly and
        !            76: straightforwardly with generic text editors or (for images composed of
        !            77: pixels) generic paint programs or (for drawings) some widely available
        !            78: drawing editor, and that is suitable for input to text formatters or
        !            79: for automatic translation to a variety of formats suitable for input
        !            80: to text formatters.  A copy made in an otherwise Transparent file
        !            81: format whose markup has been designed to thwart or discourage
        !            82: subsequent modification by readers is not Transparent.  A copy that is
        !            83: not ``Transparent'' is called ``Opaque''.
        !            84: 
        !            85: Examples of suitable formats for Transparent copies include plain
        !            86: @sc{ascii} without markup, Texinfo input format, La@TeX{} input format,
        !            87: @acronym{SGML} or @acronym{XML} using a publicly available
        !            88: @acronym{DTD}, and standard-conforming simple @acronym{HTML} designed
        !            89: for human modification.  Opaque formats include PostScript,
        !            90: @acronym{PDF}, proprietary formats that can be read and edited only by
        !            91: proprietary word processors, @acronym{SGML} or @acronym{XML} for which
        !            92: the @acronym{DTD} and/or processing tools are not generally available,
        !            93: and the machine-generated @acronym{HTML} produced by some word
        !            94: processors for output purposes only.
        !            95: 
        !            96: The ``Title Page'' means, for a printed book, the title page itself,
        !            97: plus such following pages as are needed to hold, legibly, the material
        !            98: this License requires to appear in the title page.  For works in
        !            99: formats which do not have any title page as such, ``Title Page'' means
        !           100: the text near the most prominent appearance of the work's title,
        !           101: preceding the beginning of the body of the text.

        !           107: commercially or noncommercially, provided that this License, the
        !           108: copyright notices, and the license notice saying this License applies

        !           110: conditions whatsoever to those of this License.  You may not use
        !           111: technical measures to obstruct or control the reading or further
        !           112: copying of the copies you make or distribute.  However, you may accept
        !           113: compensation in exchange for copies.  If you distribute a large enough
        !           114: number of copies you must also follow the conditions in section 3.
        !           115: 
        !           116: You may also lend copies, under the same conditions stated above, and

        !           121: 
        !           122: If you publish printed copies of the Document numbering more than 100,
        !           123: and the Document's license notice requires Cover Texts, you must enclose
        !           124: the copies in covers that carry, clearly and legibly, all these Cover
        !           125: Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
        !           126: the back cover.  Both covers must also clearly and legibly identify
        !           127: you as the publisher of these copies.  The front cover must present
        !           128: the full title with all words of the title equally prominent and
        !           129: visible.  You may add other material on the covers in addition.
        !           130: Copying with changes limited to the covers, as long as they preserve
        !           131: the title of the Document and satisfy these conditions, can be treated
        !           132: as verbatim copying in other respects.
        !           133: 
        !           134: If the required texts for either cover are too voluminous to fit
        !           135: legibly, you should put the first ones listed (as many as fit
        !           136: reasonably) on the actual cover, and continue the rest onto adjacent
        !           137: pages.
        !           138: 
        !           139: If you publish or distribute Opaque copies of the Document numbering
        !           140: more than 100, you must either include a machine-readable Transparent
        !           141: copy along with each Opaque copy, or state in or with each Opaque copy
        !           142: a publicly-accessible computer-network location containing a complete

        !           148: Transparent copy will remain thus accessible at the stated location
        !           149: until at least one year after the last time you distribute an Opaque
