<para>When -e is specified, the compilation is being performed on a
system other than where the compiled script will run. This option
disables certain configuration options that require the script to be
compiled where it is to be run and allows the script to be run on a
system that does not have Shorewall installed at all. The file
/etc/shorewall/capabilities must be present when -e is used; that
file specifies the iptables/kernel capabilities on the target
system.</para>
<para>When -d &lt;distribution&gt; is given, the script is built for
execution on the distribution specified by &lt;distro&gt;.
Currently, 'suse' is the only valid &lt;distro&gt;. Usually
specified together with -e.</para>
<para>Example:<blockquote>
<para><command>shorewall compile -ed suse foo</command></para>

<para>When the '-e' option is specified during compilation, the

on a system without Shorewall installed.</para>
