3143		-# feeds to syndicate. "Contributors" is the category used by default; you can
3144		-# configure that under Options --> Syndication.

3147		-#
3148		-# * link_rss: the URI of the Atom/RSS feed to syndicate
3149		-#
3150		-# * link_notes: user-configurable options, with keys and values

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.
