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

2065 +# * link_rss: the URI of the Atom/RSS feed to syndicate
2066 +#
2067 +# * link_notes: user-configurable options, with keys and values

2069 +#
2070 +# key: value
2071 +# cats: computers\nweb
2072 +# feed/key: value

2074 +# Keys that start with "feed/" are gleaned from the data supplied
2075 +# by the feed itself, and will be overwritten with each update.
2076 +#
2077 +# Values have linebreak characters escaped with C-style
2078 +# backslashes (so, for example, a newline becomes "\n").
2079 +#
