yeah i think its a great idea to include his conversion document, i use it all the time. Its actually possible to break that down aswell into sections rather than stating what was changed in the template.
It would look so much nicer, in my opinion, if is was titled as displayed. For example:
<b>How to add a search:</b>
<?php if(SHOW_SEARCH) { ?>
<div id="searchdiv">
<ul><ul>
<form name="search" action="<?php echo WB_URL.'/search/index'.PAGE_EXTENSION; ?>" method="post">
<h2><?php echo $TEXT['SEARCH']; ?></h2>
<div>
<input type="text" name="string" size="15" /><br /><br />
<input type="submit" name="submit" value="<?php echo $TEXT['SEARCH']; ?>" />
</div>
</form>
</ul></ul>
</div>
<?php }
?>
and so on.. that way people can simply cut and paste what they want..

the features of the WebsiteBaker tagging would be helpful too like:
<?php page_title('','[WEBSITE_TITLE]'); ?>
this is defined in the admin section at .........
see my point?

great work PeterM though...
