      <title>Configuration Information</title>

      <para>
        The main configuration file for <application>Fontconfig</application> is
        <filename>/etc/fonts/fonts.conf</filename>. Generally you do not want
        to edit this file. It will also read <filename>/etc/fonts/local.conf</filename>
        and any files in <filename class="directory">/etc/fonts/conf.d</filename>.
        To put a new font directory in the configuration, create
        (or update) the <filename>/etc/fonts/local.conf</filename> file with your
        local information or add a new file in
        <filename class="directory">/etc/fonts/conf.d</filename>. The default
        location of fonts in <application>Fontconfig</application> is:
      </para>

        </listitem>
      </itemizedlist>

      <para>
        <application>Fontconfig</application> also ships many example
        configuration files in the
        <filename class="directory">/usr/share/fontconfig/conf.avail</filename>
        directory. Symlinking specific files to
        <filename class="directory">/etc/fonts/conf.d</filename>
        will enable them. The default setup is generally good enough for
        most users. See <filename>/etc/fonts/conf.d/README</filename>
        for a description of the configuration files.
