title: use Template Toolkit for plain .html files?
body: <p>Right now I have a site that uses Perl and Template Toolkit (using the <code>Template</code> module) for pages that require calculation and/or database access but regular HTML files for the the rest of the pages.  However, I have discovered that it would be nice if I had access to templating goodness for even the "plain HTML" pages, if only for the convenience of "including" standard headers and footers, etc.</p>
  
  <p>What is the easiest way to introduce this with the least amount of disruption to the current site?  (i.e. I would prefer not to have to change all the filenames and links).</p>
