         Traditionally, programming templates into your applications goes as
         follows: First, you accumulate your variables within your PHP
         application, (maybe with database queries.) Then, you instantiate your

-        You can embed PHP into your templates with the {php}{/php} tags.
-        With this, you can setup self contained templates with their own
-        data structures for assigning their own variables. With the logic
-        embedded like this, you can keep the template &amp; logic together. This
-        way no matter where the template source is coming from, it is always
-        together as one component.
+        You can do this by writing a custom plugin for fetching the content and
+        assigning it to a template variable.

-		As of Smarty 1.5.0, there is even a cleaner way. You can include php in
-		your templates with the {include_php ...} tag. This way you can keep
-		your PHP logic separated from the template logic. See the <link
-		linkend="language.function.include.php">include_php</link> function for
