<para>
if statements in Smarty have much the same flexibility as php if
statements, with a few added features for the template engine.
Every <emphasis>if</emphasis> must be paired with an
<emphasis>/if</emphasis>. <emphasis>else</emphasis> and
<emphasis>elseif</emphasis> are also permitted. "eq", "ne","neq",
"gt", "lt", "lte", "le", "gte" "ge","is even","is odd", "is not
even","is not odd","not","mod","div by","even by","odd
by","==","!=","&gt;", "&lt;","&lt;=","&gt;=" are all valid conditional
qualifiers, and must be separated from surrounding elements by
spaces.
</para>
Every <emphasis>{if}</emphasis> must be paired with an
<emphasis>{/if}</emphasis>. <emphasis>{else}</emphasis> and
<emphasis>{elseif}</emphasis> are also permitted. The following lists
the recognized conditional qualifiers, which must be separated from
surrounding elements by spaces.</para>
