Guilty.

Actually, mine is more of a 'mung all *.txt files into *.html files while adding common headers, footers and a menu thingie', but it's been heavily used ever since I wrote it ages ago. I keep meaning to move to a real CMS with a database underneath it and CGI pages to update the information, but I never seem to have time. I've used Template Toolkit at work (nice piece of code) but it's not really what I want to use for my web sites.

Maybe this summer ..
