    <title>Contributing to this document</title>

    <para>This document is written in
    <ulink url="http://docbook.org/">Docbook XML</ulink>. The source files
    for this document are located in the subdirectory
    <filename>doc/cookbook</filename> inside the Clutter source directory.</para>

    <para>To maintain some degree of consistency, try to stick to the
    following broad guidelines about how to write Docbook for this
    cookbook:</para>

    <itemizedlist>
      <listitem>
        <para>If adding a new recipe, use the
        <filename>recipe-template.xml</filename> XML file as a basis.
        You can find it in the <filename>&lt;clutter source&gt;/doc/cookbook/</filename>
        directory.</para>
      </listitem>
      <listitem>
        <para>Try to indent your XML sensibly using 2 spaces per level
        (we're not too strict, but some indentation helps reading
        the source).</para>
      </listitem>
      <listitem>
        <para>Stick to a column width of around 80 characters.</para>
      </listitem>
      <listitem>
        <para>Use the &lt;filename&gt; element for file
        and directory names.</para>
      </listitem>
      <listitem>
        <para>Use the &lt;property&gt; element for property names
        (e.g. GObject properties).</para>
      </listitem>
      <listitem>
        <para>Use the &lt;type&gt; element for GObject class
        names.</para>
      </listitem>
      <listitem>
        <para>Use the &lt;constant&gt; element for C defines.</para>
      </listitem>
      <listitem>
        <para>Use the &lt;keycap&gt; element for keys, where
        you are referring to what's actually printed on the key, e.g.
        <keycap>Shift</keycap>. If you're referring to the key some
        other way (e.g. "the Control key"), don't use
        &lt;keycap&gt;.</para>
      </listitem>
      <listitem>
        <para>Use the &lt;function&gt; element for functions;
        the style adopted is to give the function name followed by
        empty brackets, e.g. <function>clutter_actor_set_size()</function>.
        </para>
      </listitem>
      <listitem>
        <para>Use the &lt;note&gt; element for asides which might
        otherwise interrupt the flow of the recipe.</para>
      </listitem>
      <listitem>
        <para>To include a video in a recipe, do the following:</para>
        <itemizedlist>
          <listitem>
            <para>Make the video as short as is practical, and only include
            the relevant Clutter window(s).</para>
          </listitem>

          <listitem>
            <para>Use Ogg Theora for the encoding.</para>
          </listitem>

          <listitem>
            <para>Put the file into the
            <filename>&lt;clutter source&gt;/doc/cookbook/videos</filename>
            directory. The name should be in the format
            <filename>&lt;section&gt;-&lt;recipe&gt;-&lt;identifier&gt;.ogv</filename>.
            For example: <filename>animations-fading-fade-out.ogv</filename>.</para>
          </listitem>

          <listitem>
            <para>Add the name of the file to the <varname></varname>
            in the cookbook's <filename>Makefile.am</filename>, e.g.</para>

            <informalexample>
              <programlisting>
<![CDATA[
VIDEO_FILES = \
	videos/animations-fading-fade-out.ogv \
	$(NULL)
]]>
              </programlisting>
            </informalexample>

            <para>This ensures it gets included in the distribution and
            installation.</para>
          </listitem>

          <listitem>
            <para>Use an &lt;inlinemediaobject&gt; to include it in the
            Docbook recipe file. It should look something like this:</para>

            <informalexample>
              <programlisting>
<![CDATA[
<inlinemediaobject>
  <videoobject>
    <videodata fileref="videos/cookbook-animations-fading-in-then-out.ogv"/>
  </videoobject>
  <alt>
    <para>Video showing an actor fading in then out using
    <type>ClutterState</type></para>
  </alt>
</inlinemediaobject>
]]>
              </programlisting>
            </informalexample>

            <para>The &lt;alt&gt; tag provides the text which
            is presented as a link to the file for users whose browser
            doesn't support HTML 5 embedded video.</para>
          </listitem>
        </itemizedlist>
      </listitem>
    </itemizedlist>
