Know of a good TPL tutorial?

I seriously dont even know what TPL stands for but… I’ve edited a few .tpl files and I was looking to see if anyone could point me in the direction of a good TPL tutorial website. I’ve searched google but cant find anything.

.tpl is a template file for systems like Smarty and Dreamweaver. You can’t find many tutorials because they aren’t necessary!
Read the documentation for the system you are using, that should give you an idea.
