The pages are formatted with CSS. All designs can be adjusted by hand, and custom ones can be used as well. wiki2xhtml generates the HTML pages from simple text files in the MediaWiki syntax. You can also use own (X)HTML code or other script languages inside; there are no restrictions. The GUI is composed of a Code Paste Window where you can insert wiki code that will be generated live. A click into the result, the XHTML code, copies it into the clipboard.

Blitz templates is a fast PHP template engine written in C and compiled as a PHP extension. It started as a php_templates replacement, but developed into much more. It is based on extensible template controllers (custom view classes in PHP) and weakly-active templates (simple logic in HTML). Benchmarks show that it is one of the fastest template engines for PHP, even though it's not trivial and makes Web application closer to a smart MVC-like architecture model with maximal separation of HTML from your code. It was designed for big high-load Internet projects with a lot of complex presentation logic.
