© 2004 cor

this file allows you to "syndicate" your blogs, so anyone with a
half-decent news aggregator can grab your "headlines", live.
pretty cool.

if you don't have a news aggregator, get one, it could quite
literally change your life, at least your online life. You can
look at this page in a web browser, but that's no fun.

you can edit these elements directly, over-riding init.php,
except generator admin tags, of course.
