2065 -# * link_rss: the URI of the Atom/RSS feed to syndicate
2066 -#
2067 -# * link_notes: user-configurable options, with keys and values

2069 -#
2070 -# key: value
2071 -# cats: computers\nweb
2072 -# feed/key: value

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 -#
