	3143	+# feeds to syndicate. "Contributors" is the category used by default; you can
	3144	+# configure that under Options --> Syndication.
	3145	+#
	3146	+# Fields used are:
	3147	+#
	3148	+# * link_rss: the URI of the Atom/RSS feed to syndicate
	3149	+#
	3150	+# * link_notes: user-configurable options, with keys and values
	3151	+# like so:
	3152	+#
	3153	+# key: value
	3154	+# cats: computers\nweb
	3155	+# feed/key: value
	3156	+#
	3157	+# Keys that start with "feed/" are gleaned from the data supplied
	3158	+# by the feed itself, and will be overwritten with each update.
	3159	+#
	3160	+# Values have linebreak characters escaped with C-style
	3161	+# backslashes (so, for example, a newline becomes "\n").
	3162	+#
	3163	+# The value of `cats` is used as a newline-separated list of
	3164	+# default categories for any post coming from a particular feed.
	3165	+# (In the example above, any posts from this feed will be placed
	3166	+# in the "computers" and "web" categories--in addition to any
	3167	+# categories that may already be applied to the posts.)
	3168	+#
	3169	+# Values of keys in link_notes are accessible from templates using
	3170	+# the function `get_feed_meta($key)` if this plugin is activated.
