	2032	+# feeds to syndicate. "Contributors" is the category used by default; you can
	2033	+# configure that under Options --> Syndication.
	2034	+#

	2036	+#
	2037	+# * link_rss: the URI of the Atom/RSS feed to syndicate
	2038	+#
	2039	+# * link_notes: user-configurable options, with keys and values

	2041	+#
	2042	+# key: value
	2043	+# cats: computers\nweb
	2044	+# feed/key: value
	2045	+#
	2046	+# Keys that start with "feed/" are gleaned from the data supplied
	2047	+# by the feed itself, and will be overwritten with each update.
	2048	+#
	2049	+# Values have linebreak characters escaped with C-style
	2050	+# backslashes (so, for example, a newline becomes "\n").
	2051	+#
	2052	+# The value of `cats` is used as a newline-separated list of
	2053	+# default categories for any post coming from a particular feed.

	2056	+# categories that may already be applied to the posts.)
