Smarty is a template engine for PHP.
Smarty was relatively easy to install compared to PHP / MySQL without using WAMP. Luckily someone had already installed the package on Windows and there is a link to his instructions right at the top of the "Quick Install" page. My only issues were that the package came only in a tar file instead of a zip file (I found an open source product to open the tar files called 7-Zip) and the instructions for windows installation had a slight typo (the cache and compile directories were different in the demo than in the installation instructions).
I quickly read through the documentation. It seems pretty straight forward. I look forward to using Smarty for the presentation interface of my new site.
