<para>Groff expects the environment variable PAGE to contain the default paper
size. For those in the United States, the command below is appropriate. If you
live elsewhere, you may want to change <emphasis>PAGE=letter</emphasis> to
<emphasis>PAGE=A4</emphasis>.</para>

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

<screen><userinput>PAGE=letter ./configure --prefix=/usr</userinput></screen>

<para>Compile the package:</para>

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

<para>Now install it:</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 -s soelim /usr/bin/zsoelim
ln -s eqn /usr/bin/geqn
