    <para><command>make prefix=/usr LOCAL_UNZIP=-DUSE_UNSHRINK linux</command>:
    This command overrides the <varname>prefix</varname> variable that is
    set to <filename class="directory">/usr/local</filename> in the
    <filename>Makefile</filename>, sets the <envar>LOCAL_UNZIP</envar>
    environment variable to instruct <application>UnZip</application> to use
    the shrinking algorithm based on the LZW compression
    algorithm, and builds the executables for a Linux system.
    The alternatives to 'linux' can be seen with a
    <command>make list</command> command.</para>

    <para><command>make ... linux_shlibz</command>: Build shared
    <filename>libunzip</filename> and link <application>UnZip</application> against
    it and <application>zlib</application>.</para>
