<para>Create some directories now that are needed for tests, but
will also be used as a part of installation:</para>

mkdir -pv /lib/firmware
mkdir -pv /lib/udev/rules.d
mkdir -pv /etc/udev/rules.d</userinput></screen>

<para>To test the results, run issue:</para>

<screen><userinput remap="test">make check</userinput></screen>

    <para>Install the package:</para>

<screen><userinput remap="install">make install</userinput></screen>

<para>Finally, install the man pages:</para>
