    <para>Apply the patch that adds the <quote>ascii8</quote> and
    <quote>nippon</quote> devices to Groff:</para>

<screen><userinput>patch -Np1 -i ../&groff-debian-patch;</userinput></screen>

    <note>
      <para>These devices are used by Man-DB when formatting non-English manual
      pages that are not in the ISO-8859-1 encoding. Currently, there is no
      working patch for Groff-1.19.x that adds this functionality.</para>
      <!-- Details: http://bugs.debian.org/196762 -->
    </note>

    <para>Many screen fonts don't have Unicode single quotes and dashes in them.
    Tell Groff to use the ASCII equivalents instead:</para>

<screen><userinput>sed -i -e 's/2010/002D/' -e 's/2212/002D/' \
    -e 's/2018/0060/' -e 's/2019/0027/' font/devutf8/R.proto</userinput></screen>

    <para>Groff expects the environment variable <envar>PAGE</envar> to
    contain the default paper size. For users in the United States,
    <parameter>PAGE=letter</parameter> is appropriate. Elsewhere,
    <parameter>PAGE=A4</parameter> may be more suitable. While the default
    paper size is configured during compilation, it can be overridden later
    by echoing either <quote>A4</quote> or <quote>letter</quote> to the
    <filename>/etc/papersize</filename> file.</para>

    <para>Prepare Groff for compilation:</para>

<screen><userinput>PAGE=<replaceable>&lt;paper_size&gt;</replaceable> ./configure --prefix=/usr --enable-multibyte</userinput></screen>

    <para>Compile the package:</para>

<screen><userinput>make</userinput></screen>

    <para>This package does not come with a test suite.</para>

    <para>Install the package:</para>

<screen><userinput>make install</userinput></screen>

    <para>Some documentation programs, such as <command>xman</command>,
    will not work properly without the following symlinks:</para>

<screen><userinput>ln -sv eqn /usr/bin/geqn
ln -sv tbl /usr/bin/gtbl</userinput></screen>
