    <para>Assign any shell variables that you need in this file. The file is
    always processed by <filename>/bin/sh</filename> or by the shell specified
    through SHOREWALL_SHELL in <ulink
    url="shorewall.conf.html">shorewall.conf</ulink> (5) so the full range of
    shell capabilities may be used.</para>

    <para>It is suggested that variable names begin with an upper case letter
    to distinguish them from variables used internally within the Shorewall
    programs</para>

    <para>The following variable names must be avoided. Those in <emphasis
    role="bold">bold font</emphasis> must be avoided in all Shorewall
    versions; those in regular font must be avoided in versions prior to
    4.4.8.</para>
