      release and the most current release is of the form

    <para><parameter>--localstatedir=/var</parameter>: This switch places
    the system font cache files in <filename
    class='directory'>/var/cache/fontconfig</filename>.</para>

    <para><parameter>--disable-docs</parameter>: This switch avoids building
    the documentation (the release tarball includes pre-generated
    documentation).</para>

    <para><parameter>--with-docdir=/usr/share/doc/fontconfig-&fontconfig-version;</parameter>:
    Though this parameter seems counter-intuitive following the preceding
    parameter to the <command>configure</command> command, it is used so that
    if the builder removes the <parameter>--disable-docs</parameter> parameter,
    the documentation will be installed in a versioned directory name instead
    of the default
    <filename class='directory'>/usr/share/doc/fontconfig</filename>.</para>

      <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>

      <itemizedlist spacing='compact'>
        <listitem>
          <para>/usr/share/fonts</para>

        <listitem>
          <para>~/.fonts</para>
        </listitem>
      </itemizedlist>

      <para><application>Fontconfig</application> also ships many example
      configuration files in the <filename
      class='directory'>/etc/fonts/conf.avail</filename> directory. Symlinking
      to specific files from <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.avail/README</filename> for a
      description of the configuration files.</para>
