    <title>પરિચય</title>

    <para>આ પ્રકરણ GTK-Doc ને રજૂ કરે છે અને તે શું છે અને તેને કેવી રીતે વપરાયેલ છે તેની ઝાંખી આપે છે.</para>

    <sect1 id="whatisgtkdoc">
      <title>GTK-Doc શું છે?</title>

      <para>GTK-Doc એ દસ્તાવેજ C કોડ માટે વપરાયેલ છે. તે લાઇબ્રેરીઓનાં સાર્વજનિક API નાં દસ્તાવેજ માટે વપરાયેલ છે, જેવું કે GTK+ અને GNOME લાઇબ્રેરીઓ. પરંતુ તે પણ દસ્તાવેજ કાર્યક્રમ કોડ માટે વપરાયેલ છે.</para>
    </sect1>

    <sect1 id="howdoesgtkdocwork">
      <title>GTK-Doc કામ કેવી રીતે કરે છે?</title>

      <para>GTK-Doc એ વિશિષ્ટ રીતે માળખુ થયેલ ટિપ્પણી બ્લોકોમાં સ્ત્રોત ફાઇલોની અંદર સ્થિત થયેલ વિધેયોનાં દસ્તાવેજીકરણની મદદથી કામ કરે છે, અથવા દસ્તાવેજીકરણ ટેમ્પલેટ ફાઇલોમાં ઉમેરાયેલ છે કે જે GTK-Doc વાપરે છે (છતાંપણ નોંધો કે GTK-Doc એ પણ દસ્તાવેજ વિધેયો હશે કે જે શીર્ષક ફાઇલોમાં જાહેર થયેલ છે; તે સ્થિર વિધેયો માટે આઉટપુટ ઉત્પન્ન કરતુ નથી).</para>

      <para>
        GTK-Doc consists of a number of python scripts, each performing a different step
        in the process.
      </para>

      <para>ત્યાં પ્રક્રિયામાં મુખ્ય ૫ પગલાંઓ છે:</para>

      <orderedlist>

        <listitem>
          <para><guilabel>દસ્તાવેજીકરણને લખી રહ્યા છે.</guilabel> લેખક એ દરેક વિધેયને, મેક્રો, યુનિયન વગેરે માટે દસ્તાવેજીકરણ સાથે સ્ત્રોત ફાઇલોમાં ભરે છે. (ઉત્પન્ન થયેલ ટેમ્પલેટ ફાઇલમાં ભૂતકાળની જાણકારી દાખલ થયેલ હતી, કે જે કોઇપણ રીતે અગ્રહણીય થયેલ નથી)</para>
        </listitem>

        <listitem>
          <para>
            <guilabel>Gathering information about the code.</guilabel>

            <application>gtkdoc-scan</application> scans the header files of the
            code looking for declarations of functions, macros, enums, structs, and unions.
            It creates the file <filename>&lt;module&gt;-decl-list.txt</filename> containing a list of the
            declarations, placing them into sections according to which header file they
            are in. On the first run this file is copied to <filename>&lt;module&gt;-sections.txt</filename>.
            The author can rearrange the sections, and the order of the
            declarations within them, to produce the final desired order.
            The second file it generates is <filename>&lt;module&gt;-decl.txt</filename>.
            This file contains the full declarations found by the scanner. If for
            some reason one would like some symbols to show up in the docs, where
            the full declaration cannot be found by the scanner or the declaration
            should appear differently, one can place entities similar to the ones in
            <filename>&lt;module&gt;-decl.txt</filename> into <filename>&lt;module&gt;-overrides.txt</filename>.
         </para>
         <para>
            <application>gtkdoc-scangobj</application> can also be used to dynamically query a library about
            any GObject subclasses it exports. It saves information about each
            object's position in the class hierarchy and about any GObject properties
            and signals it provides.
          </para>
         <para>
            <application>gtkdoc-scanobj</application> should not be used anymore.
            It was needed in the past when GObject was still GtkObject inside gtk+.
         </para>
        </listitem>

        <listitem>
          <para>
            <guilabel>Generating the XML and HTML/PDF.</guilabel>

            <application>gtkdoc-mkdb</application> turns the template files into
            XML files in the <filename class="directory">xml/</filename> subdirectory.
            If the source code contains documentation on functions, using the
            special comment blocks, it gets merged in here. If there are no tmpl files used
            it only reads docs from sources and introspection data.
          </para>
          <para>
            <application>gtkdoc-mkhtml</application> turns the XML files into HTML
            files in the <filename class="directory">html/</filename> subdirectory.
            Likewise <application>gtkdoc-mkpdf</application> turns the XML files into a PDF
            document called <filename>&lt;package&gt;.pdf</filename>.
          </para>
          <para>
            Files in <filename class="directory">xml/</filename> and
            <filename class="directory">html/</filename> directories are always
            overwritten. One should never edit them directly.
          </para>
        </listitem>

        <listitem>
          <para>
            <guilabel>Fixing up cross-references between documents.</guilabel>

            After installing the HTML files, <application>gtkdoc-fixxref</application> can be run to fix up any
            cross-references between separate documents. For example, the GTK+
            documentation contains many cross-references to types documented in the GLib manual.

            When creating the source tarball for distribution, <application>gtkdoc-rebase</application>
            turns all external links into web-links. When installing distributed (pregenerated) docs
            the same application will try to turn links back to local links
            (where those docs are installed).

    <para>
      The next sections describe what steps to perform to integrate GTK-Doc into
      your project. Theses sections assume we work on a project called 'meep'.
      This project contains a library called 'libmeep' and
      an end-user app called 'meeper'. We also assume you will be using autoconf
      and automake. In addition section <link linkend="plain_makefiles">plain
      makefiles or other build systems</link> will describe the basics needed to
      work in a different build setup.

    <sect1 id="settingup_docfiles">
      <title>સ્કેલેટન દસ્તાવેજીકરણને સુયોજિત કરી રહ્યા છે</title>

      <para>
        Under your top-level project directory create folders called docs/reference
        (this way you can also have docs/help for end-user documentation).
        It is recommended to create another subdirectory with the name of the doc-package.
        For packages with just one library this step is not necessary.
      </para>

      <para>
        This can then look as shown below:
        <example><title>Example directory structure</title>
          <programlisting><![CDATA[

    <sect1 id="settingup_autoconf">
      <title>autoconf સાથે એકત્રિકરણ</title>

      <para>ઘણું સરળ છે! ફક્ત તમારી <filename>configure.ac</filename> સ્ક્રિપ્ટમાં એક વાક્ય ને ઉમેરો.</para>

]]></programlisting>
        </example>
      </para>

      <para>
        This will require all developers to have gtk-doc installed. If it is
        okay for your project to have optional api-doc build setup, you can
        solve this as below. Keep it as is, as gtkdocize is looking for
        <function>GTK_DOC_CHECK</function>  at the start of a line.
        <example><title>Keep gtk-doc optional</title>
          <programlisting><![CDATA[

      <para>પહેલી દલીલ રૂપરેખાંકિત સમયે gtkdocversion માટે ચકાસવા વપરાયેલ છે. બીજી, વૈકલ્પિક દલીલ એ <application>gtkdocize</application> દ્દારા વપરાયેલ છે. <symbol>GTK_DOC_CHECK</symbol> મેક્રો પણ ઘણીબધા રૂપરેખાંકિત ફેરબદલોને ઉમેરે છે:</para>
      <orderedlist>
        <listitem><para>--with-html-dir=PATH : સ્થાપિત થયેલ દસ્તાવેજોનો પાથ</para></listitem>
        <listitem><para>--enable-gtk-doc : દસ્તાવેજીકરણ ને બિલ્ડ કરવા માટે gtk-doc ને વાપરો [default=no]</para></listitem>

      </orderedlist>

      <important>
      	<para>GTK-Doc એ મૂળભૂત રીતે નિષ્ક્રિય થયેલ છે! આગળનાં <filename>configure</filename> ને ચલાવવા માટે <option>'--enable-gtk-doc'</option> ને પસાર કરવાનું યાદ રાખો. નહિં તો પહેલીથી ઉત્પન્ન થયેલ દસ્તાવેજીકરણ સ્થાપિત થયેલ છે (કે જે વપરાશકર્તાઓ માટેનો અર્થ બને છે પરંતુ ડેવલપરો માટે નહિં).</para>
      </important>

      <para>
        Furthermore it is recommended that you have the following line inside
        your <filename>configure.ac</filename> script.
        This allows <application>gtkdocize</application> to automatically copy the
        macro definition for <function>GTK_DOC_CHECK</function> to your project.
      </para>

      <para>
        <example><title>gtkdocize માટે તૈયારી</title>

        </example>
      </para>
      <para>
        After all changes to <filename>configure.ac</filename> are made, update
        the <filename>configure</filename> file. This can be done by re-running
        <code>autoreconf -i</code> or <code>autogen.sh</code>.
      </para>
    </sect1>

    <sect1 id="settingup_automake">
      <title>automake સાથે એકત્રિકરણ</title>

      <para>
        First copy the <filename>Makefile.am</filename> from the
        <filename class="directory">examples</filename> sub directory of the
        <ulink url="https://git.gnome.org/browse/gtk-doc/tree/examples/Makefile.am">gtkdoc-sources</ulink>
        to your project's API documentation directory (
        <filename class="directory">./docs/reference/&lt;package&gt;</filename>).
        A local copy should be available under e.g.
        <filename>/usr/share/doc/gtk-doc-tools/examples/Makefile.am</filename>.
        If you have multiple doc-packages repeat this for each one.
      </para>

      <para>
        Historically GTK-Doc was generating template files where developers entered the docs.
        This turned out to be not so good (e.g. the need for having generated
        files under version control).
        Since GTK-Doc 1.9 the tools can get all the information from source comments
        and thus the templates can be avoided. We encourage people to keep
        documentation in the code. <application>gtkdocize</application> supports now
        a <option>--flavour no-tmpl</option> option that chooses a makefile that skips
        tmpl usage totally. Besides adding the option directly to the command
        invocation, they can be added also to an environment variable called <symbol>GTKDOCIZE_FLAGS</symbol>
        or set as a 2nd parameter in <symbol>GTK_DOC_CHECK</symbol> macro in the configure script.
        If you have never changed file in tmpl by hand and migrating from older gtkdoc versions,
        please remove the directory (e.g. from version control system).

      GTK-Doc uses source code comment with a special syntax for code documentation.
      Further it retrieves information about your project structure from other
      sources. During the next section you will find all information about the

        In the past most documentation had to be filled into files residing
        inside the <filename>tmpl</filename> directory. This has the
        disadvantages that the information is often not updated and also that
        the file tend to cause conflicts with version control systems.
      </para>
      <para>
        The avoid the aforementioned problems we suggest putting the

        way of documenting code.

      The scanner can handle the majority of C headers fine. In the case of
      receiving warnings from the scanner that look like a special case, one can
      hint GTK-Doc to skip over them.

      <para>
        A multiline comment that starts with an additional '*' marks a
        documentation block that will be processed by the GTK-Doc tools.
        <example><title>GTK-Doc comment block</title>
          <programlisting><![CDATA[

      <para>
        The 'identifier' is one line with the name of the item the comment is
        related to. The	syntax differs a little depending on the item.
        (TODO add table showing identifiers)
      </para>

      <para>
        The 'documentation' block is also different for each symbol type. Symbol
        types that get parameters such as functions or macros have the parameter
        description first followed by a blank line (just a '*').
        Afterwards follows the detailed description. All lines (outside program
        listings and CDATA sections) just containing a ' *' (blank-asterisk) are
        converted to paragraph breaks.
        If you don't want a paragraph break, change that into ' *  '
        (blank-asterisk-blank-blank). This is useful in preformatted text (code
        listings).

        DocBook can do more than just links. One can also have lists,
        examples, headings, and images. As of version 1.20, the
        preferred way is to use a subset of the basic text formatting
        syntax called
        <ulink url="http://daringfireball.net/projects/markdown/">Markdown</ulink>.
        On older GTK-Doc versions any documentation that includes
        Markdown will be rendered as is.  For example, list items will
        appear as lines starting with a dash.
      </para>

      <para>
        While markdown is now preferred one can mix both. One limitation here is
        that one can use docbook xml within markdown, but markdown within
        docbook xml is not supported.

      <para>
        In older GTK-Doc releases, if you need support for additional
        formatting, you would need to enable the usage of docbook
        XML tags inside doc-comments by putting <option>--xml-mode</option>
        (or <option>--sgml-mode</option>) in the variable
        <symbol>MKDB_OPTIONS</symbol> inside <filename>Makefile.am</filename>.

                    to be rare, and to have strong justifications.

                    Unstable
                    - Unstable interfaces are experimental or transitional.
                    They are typically used to give outside developers early
                    access to new or rapidly changing technology, or to provide
                    an interim solution to a problem where a more general
                    solution is anticipated.
                    No claims are made about either source or binary
                    compatibility from one minor release to the next.

      <para>
        Each symbol (function, macro, struct, enum, signal and property) is
        documented in a separate block. The block is best placed close to the
        definition of the symbols so that it is easy to keep them in sync.
        Thus functions are usually documented in the c-source and macros,
        structs and enums in the header file.

          Struct comment blocks can also be used for GObjects and GObjectClasses.
          It is usually a good idea to add a comment block for a class, if it has
          vmethods (as this is how they can be documented). For the GObject
          itself one can use the related section docs, having a separate block
          for the instance struct would be useful if the instance has public
          fields. One disadvantage here is that this creates two index entries
          of the same name (the structure and the section).

        GTK-Doc produces documentation in DocBook SGML/XML. When processing the
        inline source comments, the GTK-Doc tools generate one documentation
        page per class or module as a separate file. The master document
        includes them and place them in an order.
      </para>

      <para>
        While GTK-Doc creates a template master document for you, later runs will
        not touch it again. This means that one can freely structure the
        documentation. That includes grouping pages and adding extra pages.
        GTK-Doc has now a test suite, where also the master-document is recreated from scratch.
        Its a good idea to look at this from time to time to see if there are
        some new goodies introduced there.
      </para>

      <tip>
        <para>
          Do not create tutorials as extra documents. Just write extra chapters.
          The benefit of directly embedding the tutorial for your library into
          the API documentation is that it is easy to link for the tutorial to
          symbol documentation. Apart chances are higher that the tutorial gets
          updates along with the library.
        </para>
      </tip>

      <para>
        So what are the things to change inside the master document? For a start
        is only a little. There are some placeholders (text in square brackets)
        there which you should take care of.

      <para>
        The section file is used to organise the documentation output by
        GTK-Doc. Here one specifies which symbol belongs to which module or
        class and control the visibility (public or private).
      </para>

      <para>
        The section file is a plain text file with tags delimiting sections.
        Blank lines are ignored and lines starting with a '#' are treated as
        comment lines.
      </para>

      <note>
        <para>
          While the tags make the file look like xml, it is not. Please do not
          close tags like &lt;SUBSECTION&gt;.

]]></programlisting>
        </example>
      </para>

      <para>
        The &lt;FILE&gt; ... &lt;/FILE&gt; tag is used to specify the file name,
        without any suffix. For example, using '&lt;FILE&gt;gnome-config&lt;/FILE&gt;'
        will result in the section declarations being output in the template
        file <filename>tmpl/gnome-config.sgml</filename>, which will be
        converted into the DocBook XML file <filename>xml/gnome-config.sgml</filename>
        or the DocBook XML file <filename>xml/gnome-config.xml</filename>.
        (The name of the HTML file is based on the module name and the section
        title, or for GObjects it is based on the GObjects class name converted
        to lower case).
      </para>

      <para>
        The &lt;TITLE&gt; ... &lt;/TITLE&gt; tag is used to specify the title of
        the section. It is only useful before the templates (if used) are
        initially created, since the title set in the template file overrides
        this. Also if one uses SECTION comment in the sources, this is obsolete.
      </para>

      <para>
        You can group items in the section by using the &lt;SUBSECTION&gt; tag.
        Currently it outputs a blank line between subsections in the synopsis
        section.
        You can also use &lt;SUBSECTION Standard&gt; for standard GObject
        declarations (e.g. the functions like g_object_get_type and macros like
        G_OBJECT(), G_IS_OBJECT() etc.).
        Currently these are left out of the documentation.
        You can also use &lt;SUBSECTION Private&gt; for private declarations
        which will not be output (it is a handy way to avoid warning messages
        about unused declarations).
        If your library contains private types which you don't want to appear in
        the object hierarchy and the list of implemented or required interfaces,
        add them to a Private subsection.
        Whether you would place GObject and GObjectClass like structs in public
        or Standard section depends if they have public entries (variables,
        vmethods).
      </para>

      <para>
        You can also use &lt;INCLUDE&gt; ... &lt;/INCLUDE&gt; to specify the
        #include files which are shown in the synopsis sections.
        It contains a comma-separate list of #include files, without the angle
        brackets. If you set it outside of any sections, it acts for all
        sections until the end of the file. If you set it within a section, it
        only applies to that section.

      A GTK-Doc run generates report files inside the documentation directory.

      The <filename>&lt;package&gt;-undocumented.txt</filename> file starts with
      the documentation coverage summary. Below are two sections divided by
      blank lines. The first section lists undocumented or incomplete symbols.
      The second section does the same for section docs. Incomplete entries are
      those, which have documentation, but where e.g. a new parameter has been

      compared with the section file if that is manually maintained. The second
      lists all declarations from the headers. If a symbol is missing one could
      check if this file contains it.
    </para>

    <para>
      If the project is GObject based, one can also look into the files produced

      <filename>&lt;package&gt;.signals.txt</filename>. If there are missing
      symbols in any of those, one can ask GTK-Doc to keep the intermediate
      scanner file for further analysis, by running it as
      <command>GTK_DOC_KEEP_INTERMEDIATE=1 make</command>.

        extra tmpl build step at all, by using <option>--flavour no-tmpl</option>
        in <filename>configure.ac</filename>. If you don't have a <filename class="directory">tmpl</filename>

    <title>0. PREAMBLE</title>
    <para>
      The purpose of this License is to make a manual, textbook, or
      other written document <quote>free</quote> in the sense of
      freedom: to assure everyone the effective freedom to copy and
      redistribute it, with or without modifying it, either
      commercially or noncommercially. Secondarily, this License
      preserves for the author and publisher a way to get credit for
      their work, while not being considered responsible for
      modifications made by others.
    </para>
    
    <para>
      This License is a kind of <quote>copyleft</quote>, which means
      that derivative works of the document must themselves be free in
      the same sense. It complements the GNU General Public License,
      which is a copyleft license designed for free software.
    </para>
    
    <para>
      We have designed this License in order to use it for manuals for
      free software, because free software needs free documentation: a
      free program should come with manuals providing the same
      freedoms that the software does. But this License is not limited
      to software manuals; it can be used for any textual work,
      regardless of subject matter or whether it is published as a
      printed book. We recommend this License principally for works
      whose purpose is instruction or reference.
    </para>
  </sect1>
  <sect1 id="fdl-section1">
    <title>1. APPLICABILITY AND DEFINITIONS</title>
    <para id="fdl-document">
      This License applies to any manual or other work that contains a
      notice placed by the copyright holder saying it can be
      distributed under the terms of this License. The
      <quote>Document</quote>, below, refers to any such manual or
      work. Any member of the public is a licensee, and is addressed
      as <quote>you</quote>.
    </para>
    
    <para id="fdl-modified">
      A <quote>Modified Version</quote> of the Document means any work
      containing the Document or a portion of it, either copied
      verbatim, or with modifications and/or translated into another
      language.
    </para>
	
    <para id="fdl-secondary">
      A <quote>Secondary Section</quote> is a named appendix or a
      front-matter section of the <link linkend="fdl-document">Document</link> that deals exclusively
      with the relationship of the publishers or authors of the
      Document to the Document's overall subject (or to related
      matters) and contains nothing that could fall directly within
      that overall subject. (For example, if the Document is in part a
      textbook of mathematics, a Secondary Section may not explain any
      mathematics.)  The relationship could be a matter of historical
      connection with the subject or with related matters, or of
      legal, commercial, philosophical, ethical or political position
      regarding them.
    </para>

    <para id="fdl-invariant">
      The <quote>Invariant Sections</quote> are certain <link linkend="fdl-secondary"> Secondary Sections</link> whose titles
      are designated, as being those of Invariant Sections, in the
      notice that says that the <link linkend="fdl-document">Document</link> is released under this
      License.
    </para>
    
    <para id="fdl-cover-texts">
      The <quote>Cover Texts</quote> are certain short passages of
      text that are listed, as Front-Cover Texts or Back-Cover Texts,
      in the notice that says that the <link linkend="fdl-document">Document</link> is released under this
      License.
    </para>
	
    <para id="fdl-transparent">
      A <quote>Transparent</quote> copy of the <link linkend="fdl-document"> Document</link> means a machine-readable
      copy, represented in a format whose specification is available
      to the general public, whose contents can be viewed and edited
      directly and straightforwardly with generic text editors or (for
      images composed of pixels) generic paint programs or (for
      drawings) some widely available drawing editor, and that is
      suitable for input to text formatters or for automatic
      translation to a variety of formats suitable for input to text
      formatters. A copy made in an otherwise Transparent file format
      whose markup has been designed to thwart or discourage
      subsequent modification by readers is not Transparent.  A copy
      that is not <quote>Transparent</quote> is called
      <quote>Opaque</quote>.
    </para>
    
    <para>
      Examples of suitable formats for Transparent copies include
      plain ASCII without markup, Texinfo input format, LaTeX input
      format, SGML or XML using a publicly available DTD, and
      standard-conforming simple HTML designed for human
      modification. Opaque formats include PostScript, PDF,
      proprietary formats that can be read and edited only by
      proprietary word processors, SGML or XML for which the DTD
      and/or processing tools are not generally available, and the
      machine-generated HTML produced by some word processors for
      output purposes only.
    </para>
    
    <para id="fdl-title-page">
      The <quote>Title Page</quote> means, for a printed book, the
      title page itself, plus such following pages as are needed to
      hold, legibly, the material this License requires to appear in
      the title page. For works in formats which do not have any title
      page as such, <quote>Title Page</quote> means the text near the
      most prominent appearance of the work's title, preceding the
      beginning of the body of the text.

    <title>2. VERBATIM COPYING</title>
    <para>
      You may copy and distribute the <link linkend="fdl-document">Document</link> in any medium, either
      commercially or noncommercially, provided that this License, the
      copyright notices, and the license notice saying this License
      applies to the Document are reproduced in all copies, and that
      you add no other conditions whatsoever to those of this
      License. You may not use technical measures to obstruct or
      control the reading or further copying of the copies you make or
      distribute. However, you may accept compensation in exchange for
      copies. If you distribute a large enough number of copies you
      must also follow the conditions in <link linkend="fdl-section3">section 3</link>.
    </para>
    
    <para>
      You may also lend copies, under the same conditions stated
      above, and you may publicly display copies.
    </para>
    </sect1>
    
  <sect1 id="fdl-section3">
    <title>3. COPYING IN QUANTITY</title>
    <para>
      If you publish printed copies of the <link linkend="fdl-document">Document</link> numbering more than 100,
      and the Document's license notice requires <link linkend="fdl-cover-texts">Cover Texts</link>, you must enclose
      the copies in covers that carry, clearly and legibly, all these
      Cover Texts: Front-Cover Texts on the front cover, and
      Back-Cover Texts on the back cover. Both covers must also
      clearly and legibly identify you as the publisher of these
      copies. The front cover must present the full title with all
      words of the title equally prominent and visible. You may add
      other material on the covers in addition. Copying with changes
      limited to the covers, as long as they preserve the title of the
      <link linkend="fdl-document">Document</link> and satisfy these
      conditions, can be treated as verbatim copying in other
      respects.
    </para>
    
    <para>
      If the required texts for either cover are too voluminous to fit
      legibly, you should put the first ones listed (as many as fit
      reasonably) on the actual cover, and continue the rest onto
      adjacent pages.
    </para>
    
    <para>
      If you publish or distribute <link linkend="fdl-transparent">Opaque</link> copies of the <link linkend="fdl-document">Document</link> numbering more than 100,
      you must either include a machine-readable <link linkend="fdl-transparent">Transparent</link> copy along with
      each Opaque copy, or state in or with each Opaque copy a
      publicly-accessible computer-network location containing a
      complete Transparent copy of the Document, free of added
      material, which the general network-using public has access to
      download anonymously at no charge using public-standard network
      protocols. If you use the latter option, you must take
      reasonably prudent steps, when you begin distribution of Opaque
      copies in quantity, to ensure that this Transparent copy will
      remain thus accessible at the stated location until at least one
      year after the last time you distribute an Opaque copy (directly
      or through your agents or retailers) of that edition to the
      public.
    </para>
    
    <para>
      It is requested, but not required, that you contact the authors
      of the <link linkend="fdl-document">Document</link> well before
      redistributing any large number of copies, to give them a chance
      to provide you with an updated version of the Document.

      sections <link linkend="fdl-section2">2</link> and <link linkend="fdl-section3">3</link> above, provided that you release
      the Modified Version under precisely this License, with the
      Modified Version filling the role of the Document, thus
      licensing distribution and modification of the Modified Version
      to whoever possesses a copy of it. In addition, you must do
      these things in the Modified Version:

      do this, add their titles to the list of <link linkend="fdl-invariant">Invariant Sections</link> in the
      Modified Version's license notice.  These titles must be
      distinct from any other section titles.

      You may add a section entitled <quote>Endorsements</quote>,
      provided it contains nothing but endorsements of your <link linkend="fdl-modified">Modified Version</link> by various

      has been approved by an organization as the authoritative
      definition of a standard.

    <para>
      You may add a passage of up to five words as a <link linkend="fdl-cover-texts">Front-Cover Text</link>, and a passage
      of up to 25 words as a <link linkend="fdl-cover-texts">Back-Cover Text</link>, to the end of
      the list of <link linkend="fdl-cover-texts">Cover Texts</link>
      in the <link linkend="fdl-modified">Modified Version</link>.
      Only one passage of Front-Cover Text and one of Back-Cover Text
      may be added by (or through arrangements made by) any one
      entity. If the <link linkend="fdl-document">Document</link>
      already includes a cover text for the same cover, previously
      added by you or by arrangement made by the same entity you are
      acting on behalf of, you may not add another; but you may
      replace the old one, on explicit permission from the previous
      publisher that added the old one.

      with other documents released under this License, under the
      terms defined in <link linkend="fdl-section4">section 4</link>

      and list them all as Invariant Sections of your combined work in
      its license notice.

      The combined work need only contain one copy of this License,

      multiple Invariant Sections with the same name but different
      contents, make the title of each such section unique by adding
      at the end of it, in parentheses, the name of the original
      author or publisher of that section if known, or else a unique
      number. Make the same adjustment to the section titles in the
      list of Invariant Sections in the license notice of the combined
      work.

      In the combination, you must combine any sections entitled

      of this License in the various documents with a single copy that

      A compilation of the <link linkend="fdl-document">Document</link> or its derivatives with

      volume of a storage or distribution medium, does not as a whole

      for the compilation.  Such a compilation is called an
      <quote>aggregate</quote>, and this License does not apply to the
      other self-contained works thus compiled with the Document , on
      account of their being thus compiled, if they are not themselves
      derivative works of the Document.  If the <link linkend="fdl-cover-texts">Cover Text</link> requirement of <link linkend="fdl-section3">section 3</link> is applicable to these
      copies of the Document, then if the Document is less than one
      quarter of the entire aggregate, the Document's Cover Texts may
      be placed on covers that surround only the Document within the
      aggregate. Otherwise they must appear on covers around the whole

      Translation is considered a kind of modification, so you may

      holders, but you may include translations of some or all
      Invariant Sections in addition to the original versions of these
      Invariant Sections. You may include a translation of this
      License provided that you also include the original English
