CMS (flat-file database)

I need cms done in php which will access flat-file text database ( no sql ) I need admin interface where I can make - front page ( content, meta tags, title, meta info for tags ( you know, bigger, smaller font ) ) - articles ( content, meta tags, title, meta info for tags ) I need only one file php backend and [login to view URL] with template system ! To see what I mean check sNews from [login to view URL] and even more appropriate [login to view URL]! but I need cms to function like sNews... you know to include functions ! Templates should be edited like this - function title ( where meta tags and title goes ) - funtion content ( where content goes - article ) - function menu ( links to articles ) - function tags ( bigger, smaller, fonts ) - output articles with those tags ! I own all rights of the application Really simple cms...
