How Can I Rename The Product Details Heading?

We were asked to rename the standard "Details" heading on the product view page to something other than "Details". Since it is the Description attribute this should be easy to rename, right? Ha! You'd like that, wouldn't you! Unfortunately that doesn't work. I looked at the template catalog/product/view.phtml and found a rather confusing bit of code:

    <div class="product-collateral">
<?php foreach ($this->getChildGroup('detailed_info', 'getChildHtml') as $alias => $html):?>
        <div class="box-collateral <?php echo "box-{$alias}"?>">
            <?php if ($title = $this->getChildData($alias, 'title')):?>
            <h2><?php echo $this->escapeHtml($title); ?></h2>
            <?php endif;?>
            <?php echo $html; ?>
        </div>
<?php endforeach;?>
        <?php echo $this->getChildHtml('upsell_products') ?>
        <?php echo $this->getChildHtml('product_additional_data') ?>
    </div>

Notice the 5th line. This is where 'Details' is printed out. But where does it actually come from? Let's take a look at your theme's layout/catalog.xml file. Find the block "catalog/product_view_description". It explains a lot:

<block type="catalog/product_view_description" name="product.description" as="description" template="catalog/product/view/description.phtml">
    <action method="addToParentGroup"><group>detailed_info</group></action>
</block>

We find that it loads the template catalog/product/view/description.phtml. And that's where it comes from. Take a look at the file:

<?php $_description = $this->getProduct()->getDescription(); ?>
<?php if ($_description): ?>
    <h2><?php echo $this->__('Details') ?></h2>
    <div class="std">
        <?php echo $this->helper('catalog/output')->productAttribute($this->getProduct(), $_description, 'description') ?>
    </div>
<?php endif; ?>

There you have it. Now you can change it back to "Description" so it actually matches the attributes title. Or of course to whatever you like...
