<para>Prior to Shorewall 4.5.11, comments were specified by a line having
COMMENT as the first token. The remainder of the line is treated as a
comment to be attached to rules.</para>
<para>In Shorewall 4.5.11, the ?COMMENT directive was created to
centralize processing of COMMENT directives. The old entries, while still
supported, are now deprecated.</para>
<para>The ?COMMENT directive is as follows:</para>
<variablelist>
<varlistentry>
<term>COMMENT [ <replaceable>comment</replaceable> ]</term>
<listitem>
<para>If <replaceable>comment</replaceable> is present, it will
appear enclosed in /*....*/ in the output of the <command>shorewall
show </command>and <command>shorewall dump</command> commands. If no
<replaceable>comment</replaceable> is present, the rules generated
by following entries will not have comments attached.</para>
