    <title>Inline Tags</title>

  </header>

  <p>Inline tags are typically used within block tags, for example to
    highlight a word within a paragraph.</p>

  <section>
    <marker id="brTAG"></marker>
    <title>&lt;br&gt; - Line Break</title>

    <p>Forces a newline. The <c><![CDATA[<br>]]></c> tag is both a
      block- and an inline tag and is described in
      the <seealso marker="block_tags#brTAG">Block Tags</seealso>
      section.</p>
  </section>

  <section>
    <marker id="cTAG"></marker>
    <title>&lt;c&gt; - Code</title>

    <p>Highlights things like variables and file names in a text flow.
      Can contain plain text only. Newlines and tabs are ignored as
      opposed to the <seealso marker="block_tags#codeTAG">code</seealso>
      tag. All <seealso marker="character_entities">character
	entities</seealso> are expanded. Example:</p>
    <pre>
&lt;p>Returns &lt;c>true&lt;/c> if &lt;c>Term&lt;/c> is an integer.&lt;/p>
    </pre>
    <p>results in:</p>
    <p>Returns <c>true</c> if <c>Term</c> is an integer.</p>
  </section>

  <section>
    <marker id="emTAG"></marker>
    <title>&lt;em&gt; - Emphasis</title>

    <p>Highlights words which are important within a text flow. Example:
    </p>
    <pre>
&lt;p>The application &lt;em>must&lt;/em> be up and running.&lt;/p>
    </pre>
    <p>results in:</p>
    <p>The application <em>must</em> be up and running.</p>

    <p>Contains plain text or a
      <seealso marker="#cTAG">&lt;c&gt;</seealso> tag.</p>
  </section>

  <section>
    <marker id="markerTAG"/>
    <title>&lt;marker&gt; - Marker</title>

    <p>Used as an anchor for hypertext references. The <c>id</c>
      attribute defines the name of the marker. Example:</p>
    <marker id="marker_example"/>
    <pre>
&lt;marker id="marker_example"/&gt;
    </pre>
  
    <p>The <seealso marker="#seealsoTAG">&lt;seealso&gt;</seealso> tag
      is used to refer to the marker.</p>

    <p>The <c><![CDATA[<marker>]]></c> tag is both a block- and an
      inline tag.</p>
  </section>

  <section>
    <marker id="pathTAG"></marker>
    <title>&lt;path&gt; - Path</title>

    <p>Highlights file paths. The attributes <c>unix</c> and
      <c>windows</c> makes it possible to specify different paths for
      different file path notations. Default for both are "".
      Example:</p>
    <pre>
&lt;p>Look at the &lt;path unix=".profile" windows="win.ini"&gt;start-up file&lt;/path&gt;
  if you intend to alter the initial behavior.&lt;/p>
    </pre>
    <p>If no <c>ptype</c> option is specified when calling
      <seealso marker="docb_transform#file/1">docb_transform:file/1,2</seealso>,
      this simply results in:</p>
    <p>"Look at the <path>start-up file</path>
      if you intend to alter the initial behavior."</p>

    <p>If both the options <c>{ptype,unix}</c> and
      <c>{ptype,windows}</c> are specified, the example instead results
      in:</p>
    <p>"Look at the <path unix=".profile" windows="win.ini">start-up file</path>
      if you intend to alter the initial behavior."</p>
  </section>

  <section>
    <marker id="seealsoTAG"></marker>
    <title>&lt;seealso&gt; - Local Cross Reference</title>

    <p>A cross reference (hypertext link) to a marker in the same file,
      a marker in another file, or (the top of) another file, given by
      the <c>marker</c> attribute. Must contain plain text. Examples:
      </p>

    <pre><![CDATA[
      <seealso marker="#marker_example">marker example</seealso>
    ]]></pre>
    <p>results in:
      <seealso marker="#marker_example">marker example</seealso>
      (a hypertext link to the marker example above).</p>

    <pre><![CDATA[
      <seealso marker="block_tags#markerTAG">marker tag</seealso>
    ]]></pre>
    <p>results in:
      <seealso marker="block_tags#markerTAG">marker tag</seealso>
      (a hypertext link to the marker section in the Block Tags
      chapter).</p>
    
    <pre><![CDATA[
      <seealso marker="overview">Overview</seealso>
    ]]></pre>
    <p>results in:
      <seealso marker="overview">Overview</seealso>
      (a hypertext link to the Overview chapter).</p>

    <p>Note the use of "#" before the name of the marker. Note also
      that the filename extension <c>.html</c> is omitted. This is
      because the default behavior of DocBuilder is to translate
      <c><![CDATA[<seealso marker="File#Marker">text</seealso>]]></c>
      to <c><![CDATA[<A HREF="File.html#Marker">text</A>]]></c>.</p>

    <p>The default behaviour can be modified by using the callback
      module option to <c>docb_transform:file/1,2</c> and defining a
      callback function
      <seealso marker="docb_transform#Module:seealso-1">Module:seealso/1</seealso>.
      This possibility is for example used in OTP to resolve cross
      references between applications.</p>
  </section>
    
  <section>
    <marker id="urlTAG"></marker>
    <title>&lt;url&gt; - Non-Local Cross Reference</title>

    <p>A reference to a file outside the documentation, a web address or
      similar, given by the <c>href</c> attribute. Must contain plain
      text. Example:</p>
    <pre><![CDATA[
<url href="http://www.erlang.org">erlang.org</url>
    ]]></pre>
    <p>results in: <url href="http://www.erlang.org">erlang.org</url>
    </p>
  </section>

  <section>
    <marker id="termTAG"></marker>
    <marker id="termdefTAG"></marker>
    <title>&lt;term&gt;, &lt;termdef&gt; - Glossary</title>

    <p>Used to highlight a term with a local (for this document only) or
      global definition. The identity of the term is given by
      the <c>id</c> attribute.</p>

    <p>For a locally defined term, the tag contains a
      <c>&lt;termdef&gt;</c>, which in turn contains an explanation of
      the term as plain text. Example:</p>
    <pre><![CDATA[
<term id="HTML"><termdef>Hyper-Text Markup Language</termdef></term>
      ]]></pre>

    <p>For a globally defined term, the tag is empty. Example:</p>
    <pre><![CDATA[
<term id="HTML"/>
      ]]></pre>

    <p>Global definitions are given to DocBuilder in a file, using the
      <seealso marker="docb_transform#file/1">docb_transform:file/1,2</seealso>
      option <c>term_defs</c>. The file should contain a list of tuples,
      one for each term definition, on the format
      <c>{Id,Name,Definition,Owner}</c>. The <c>Owner</c> part is just
      for administration, if there are several people contributing to a
      term definition file. Example:</p>
    <pre>
[...,
 {"HTML", "HTML", "Hyper-Text Markup Language", "Gunilla"},
 ...].
    </pre>

    <p>DocBuilder will collect both local and global definitions in a
      glossary, which can be reached from a link in the left frame of
      the HTML documentation.</p>

    <p>In the generated HTML, it is the term name which will be visible.
      For locally defined terms, the id and the name are the same.
      The name has a hypertext link to the definition in the glossary.
      Example:</p>
    <pre><![CDATA[
<term id="HTML"><termdef>Hyper-Text Markup Language</termdef></term>
      ]]></pre>
    <p>results in: <term id="HTML"><termdef>Hyper-Text Markup Language</termdef></term>
    </p>

    <p>If a term is defined both locally and globally, the global
      definition takes precedence.</p>
  </section>

  <section>
    <marker id="citeTAG"></marker>
    <marker id="citedefTAG"></marker>
    <title>&lt;cite&gt;, &lt;citedef&gt; - Bibliography</title>

    <p>Works the same way as <c>&lt;term&gt;</c> and
      <c>&lt;termdef&gt;</c>, but for a bibliography list rather than
      a glossary.</p>

    <p>A global bibliography list is given to DocBuilder in a file,
      using the <seealso marker="docb_transform#file/1">docb_transform:file/1,2</seealso>
      option <c>cite_defs</c>. The file should contain a list of tuples,
      one for each cite, on the format
      <c>{Id,Title,Info,Owner}</c>. The <c>Owner</c> part is just
      for administration, if there are several people contributing to a
      bibliography file. Example:</p>
    <pre>
