Templayer currently supports only HTML generation, but its simple design is easily extended to support other file formats.

Templayer was created to offer an alternative to the more common ways of generating dynamic HTML: embedding code within the HTML (PHP etc.), or embedding HTML within code (traditional CGI). Neither of these methods allow for a clean separation of the form, or layout, of a page and the function of page generation. Instead of mixing HTML and Python, two rich and extremely expressive languages, we can add a small amount of syntax to each and keep the two separate and coherent.
