	21	+# USAGE: once FeedWordPress is installed, you manage just about everything from
	22	+# the WordPress Dashboard, under Options --> Syndication or Links --> Syndicated
	23	+# To ensure that fresh content is added as it becomes available, get your
	24	+# contributors 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 see `update-feeds.php`

	1887	+# feeds to syndicate. "Contributors" is the category used by default; you can
	1888	+# configure that under Options --> Syndication.
	1889	+#
	1890	+# Fields used are:
	1891	+#
	1892	+# * link_rss: the URI of the Atom/RSS feed to syndicate
	1893	+#
	1894	+# * link_notes: user-configurable options, with keys and values
	1895	+# like so:
	1896	+#
	1897	+# key: value
	1898	+# cats: computers\nweb
	1899	+# feed/key: value
	1900	+#
	1901	+# Keys that start with "feed/" are gleaned from the data supplied
	1902	+# by the feed itself, and will be overwritten with each update.
	1903	+#
	1904	+# Values have linebreak characters escaped with C-style
	1905	+# backslashes (so, for example, a newline becomes "\n").
	1906	+#
	1907	+# The value of `cats` is used as a newline-separated list of
	1908	+# default categories for any post coming from a particular feed.
	1909	+# (In the example above, any posts from this feed will be placed
	1910	+# in the "computers" and "web" categories--*in addition to* any
	1911	+# categories that may already be applied to the posts.)
	1912	+#
	1913	+# Values of keys in link_notes are accessible from templates using
	1914	+# the function `get_feed_meta($key)` if this plugin is activated.
