To kill the template system, in each file you would need to find and comment out / delete:
PHP Code:
echo $template;
Then you would just echo the $article_content and $article_title variables out. These contain all of the text that is generated by the script for the most part. :)
You can also echo the other variables for the script out such as the one that controls if a user is logged in or not, or you can integrate that all some other way.
