520246 Simple CMS

I need a very simple CMS backend script, where I can include this script in sections of a website. Example: If I created a "About Us" page, I dont need the whole page to have CMS, just a small section. So if I built the page, and I put a table or div area at the bottom that says "List of products", I want the ability to login on a backend area, and add/delete/modify this list.
