FLATE is a library used to handle HTML template files outside C code as well as basic CGI input/output such as retrieving variables from HTML forms or cookies. Template files can be manipulated from the C code with various functions to change variables and display or hide part of the HTML code. The best way to sum it up would be that printf("<html>hello</html>"); is now history.

Comment Script is a script that allows comments to be left on any existing PHP or HTML page. By default, the script shows name, e-mail, homepage, title, and comment fields, though any can be disabled. The "comment" field is mandatory and must be filled out before the form can be submitted. In order to prevent the script from being abused by automatic spam bots, you can enable the CAPTCHA feature. The script then asks your visitors to enter a text they see in the image below the comment form into an input box. It also features an admin area where comments can be edited and deleted and the front-end language set.
