## Samples

Templating System : Demo

As the links reveal, the "Data" files have the extension `.tcl` and the "Template" files have `.adp`. If you want to see a little behind the scenes, you can look at the Tcl code into which we compile the template. The last column will deliver the resulting page to your browser.
