			<para>
			 Comandos {if} no Smarty tem muito da mesma flexibilidade do php,
			 com algumas caracter<65>sticas <20> mais para o sistema de template. 
			 Todo <emphasis>if</emphasis> deve ter o seu 
			<emphasis>/if</emphasis>. <emphasis>else</emphasis> e
			<emphasis>elseif</emphasis> tamb<6D>m s<>o permitidos. Todos os 
			condicionais do PHP s<>o reconhecidos, tais como ||, or, &amp;&amp;, and, etc.
			</para>

			<para>
			 A seguir est<73> uma lsita dos qualificadores, que devem estar separados dos elementos 
			 por espa<70>o. Note que itens listado entre [conchetes] s<>o opcionais. Os equivalentes 
			 em PHP s<>o mostrados quando aplic<69>veis.
