Thanks to the suggestion about Template Toolkit, I had some more terms to search...

I've yet to fully investigate "TT" but I've already found an interesting article:

• http://perl.apache.org/docs/tutorials/tmpl/comparison/comparison.html

It compares the various templating options available, which is handy as I'm not sure how fancy I need to be with my web sites and their structures.

Many thanks for the helpful pointer.
