20		-# USAGE: once FeedWordPress is installed, you manage just about everything from
21		-# the WordPress Dashboard, under the Syndication menu. To ensure that fresh
22		-# content is added as it becomes available, you can convince your contributors
23		-# to put your XML-RPC URI (if WordPress is installed at
24		-# <http://www.zyx.com/blog>, XML-RPC requests should be sent to
25		-# <http://www.zyx.com/blog/xmlrpc.php>), or update manually under the
26		-# Syndication menu, or set up automatic updates under Syndication --> Settings,
27		-# or use a cron job.
