index.php5 is the front controller (waitress) of your homepage and is implemented very simple… All content orders have to be done through this script.

The only thing index.php5 is doing is:

• Taking your link order, which is represented through URL GET parameter of index.php5 (->www.yoursite.org/index.php5?content=anylink)
• Calling the template (making the plates ready and layouting them, so cook only needs to put the eaty parts on them)
• Passing the link information to the cms processor (cook, which prepares wished sushi dish)
