  <section>
    <title>Git Taxonomy</title>

    <para>The Shorewall Git tree at Sourceforge serves as the master
    repository for Shorewall 4.4 and later versions. It is not possible to
    simply export a directory from Git and run the
    <command>install.sh</command> script in that directory. A build step is
    required to produce a directory that is suitable for the
    <command>install.sh</command> script to run in.</para>

    <section>
      <title>trunk</title>

      <para>The development branch of each product is kept here.</para>

      <itemizedlist>
        <listitem>
          <para>Shorewall</para>

        </listitem>
      </itemizedlist>

      <para>There are also several other directories which are described in
      the following sub-sections.</para>

      <section>
        <title>trunk/docs</title>

        <para>The development release XML documents. Depending on the point in
        the release cycle, these documents may also apply to the current
        stable version. In that case, there is no docs directory in that
        release's directory in <emphasis
        role="bold">branches</emphasis>.</para>
      </section>

      <section>
        <title>trunk/manpages, trunk/manpages6, trunk/manpages-lite and
        trunk/manpages6-lite</title>

        <para>The development release XML manpages. Depending on the point in
        the release cycle, these documents may also apply to the current
        stable version.</para>
      </section>
    </section>

    <section>
      <title>tools</title>

      <para>This is where the release and build tools are kept. There are two
      subordinate directories:</para>

      <variablelist>
        <varlistentry>
          <term>trunk/tools/build</term>

          <listitem>
            <para>Tools for building and uploading new releases.</para>
          </listitem>
        </varlistentry>

        <varlistentry>
          <term>trunk/tools/web</term>

          <listitem>
            <para>Tools for publishing web content</para>
          </listitem>
        </varlistentry>
      </variablelist>
    </section>

    <section>
      <title>web</title>

      <para>The files from the web site that are maintained in HTML format.
      are kept in this directory.</para>
    </section>
  </section>

  <section>
    <title>Build Tools</title>

    <para>As described above, the build tools are kept in <filename
    class="directory">trunk/tools/build.</filename> They are described in the
    following sections.</para>

    <section>
      <title>setversion</title>

      <para>The <command>setversion</command> script updates the version
      number in a directory. The script is run with the current working
      directory being <filename class="directory">trunk</filename>.</para>

      <blockquote>
        <para><command>setversion</command>
        <replaceable>version</replaceable></para>
      </blockquote>

      <para>The <replaceable>version</replaceable> may either be a minor
      version or a patch version.</para>
    </section>

    <section>
      <title>build44</title>

      <para>This is the script that builds Shorewall packages from Git.</para>

      <para>The script copies content from Git using the <command>git
      archive</command> command. It then uses that content to build the
      packages. In addition to the usual Gnu utilities, the following software
      is required:</para>

      <variablelist>
        <varlistentry>
          <term>rpmbuild</term>

          <listitem>

          </listitem>
        </varlistentry>

        <varlistentry>
          <term>xmlto</term>

          <listitem>
            <para>Required to convert the XML manpages to manpages. Be sure
            that you have a recent version; I use 0.0.23.</para>
          </listitem>
        </varlistentry>
      </variablelist>

      <para>You should ensure that you have the latest script. The scripts
      change periodically as we move through the release cycles.</para>

      <para>The scripts may need to be modified to fit your particular
      environment. There are a number of variables that are set near the front
      of the script:</para>

      <variablelist>
        <varlistentry>
          <term>STYLESHEET</term>

          <listitem>

            Docbook XSL Stylesheets installation.</para>

          </listitem>
        </varlistentry>
      </variablelist>

      <para>The scripts assume that there will be a separate <firstterm>build
      directory</firstterm> per major release. To build a release, you cd to
      the appropriate directory and run the build script.</para>

      <para>The general form of the build command is:</para>

      <blockquote>
        <para><command>build44</command> [ -<replaceable>options</replaceable>
        ] <replaceable>release</replaceable> [ <replaceable>prior
