This is an example of a catpress page.
No database, no javascript. Just a little php and a directory tree of plain text and html files. Fast! Because it does almost nothing. But, you get consistent formatting across pages, consistent headers, footers. Style is in-lined with the page load so there's never missing css and the page can't get caught in a partially-loaded state. Browser nav buttons still just work.
There are two things to change in index.php:
To create a page, just make a folder in the directory of index.php. Within that folder, place the file title and body. Title should just contain text, and the body should be html tags.
Instead of 'body' the files 'body0' 'body1', etc can be created, and multi-page articles will be created.
