	2060	+# feeds to syndicate. "Contributors" is the category used by default; you can
	2061	+# configure that under Options --> Syndication.
	2062	+#
	2063	+# Fields used are:
	2064	+#
	2065	+# * link_rss: the URI of the Atom/RSS feed to syndicate
	2066	+#
	2067	+# * link_notes: user-configurable options, with keys and values
	2068	+# like so:
	2069	+#
	2070	+# key: value
	2071	+# cats: computers\nweb
	2072	+# feed/key: value
	2073	+#
	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	+#
	2080	+# The value of `cats` is used as a newline-separated list of
	2081	+# default categories for any post coming from a particular feed.
	2082	+# (In the example above, any posts from this feed will be placed
	2083	+# in the "computers" and "web" categories--*in addition to* any
	2084	+# categories that may already be applied to the posts.)
	2085	+#

	2087	+# the function `get_feed_meta($key)` if this plugin is activated.
