<h1>The <for> Tag</h1><p>
The <for> tag provides a quick way to iterate through a list of items.
</p>
<p>
It requires two attributes, <em>name</em> and <em>values</em>; the content item named
<em>name</em> is set to each space-separated value in the <em>values</em> string, and
the text inside the block is processed.
</p>
<a name="Supported_Attributes" id="Supported_Attributes"><h2>Supported Attributes</h2></a><dl>
<dt>
<em>name</em>
</dt>
<dd>
The name of the variable which will be set to each
value in the <em>values</em> list in turn (if you know your comp-sci
lingo, the iterator).
</dd>
<dt>
<em>values</em>
</dt>
<dd>
A space-separated list of values which is iterated
through.
</dd>
<dt>
<em>namesubst</em>
</dt>
<dd>
A Perl s/// substitution; each value in the <em>values</em>
list will be processed by this, if set.
</dd>
</dl>
<p>
Variable references to <strong>${<em>name</em>}</strong> are processed immediately, so
you can use this variable inside another variable reference, like this:
<code>${all_${name}_text}</code> .
</p>
<a name="Example" id="Example"><h2>Example</h2></a><p>
Here's an example, taken from my own <a href="http://jmason.org/">home site</a>:
</p>
<p>
<!--etsafe-->
<pre>
<!-- Create output for files in top dir -->
<for name="out" values="index contact work nonwork home">
<out file="${out}.html" name="${out}">
${jmason_template}
</out>
</for>
</pre><!--/etsafe-->
