2953 -# feeds to syndicate. "Contributors" is the category used by default; you can
2954 -# configure that under Options --> Syndication.

2956 -# Fields used are:
2957 -#
2958 -# * link_rss: the URI of the Atom/RSS feed to syndicate
2959 -#
2960 -# * link_notes: user-configurable options, with keys and values
2961 -# like so:
2962 -#
2963 -# key: value
2964 -# cats: computers\nweb
2965 -# feed/key: value
2966 -#
2967 -# Keys that start with "feed/" are gleaned from the data supplied
2968 -# by the feed itself, and will be overwritten with each update.
2969 -#
2970 -# Values have linebreak characters escaped with C-style
2971 -# backslashes (so, for example, a newline becomes "\n").
2972 -#
2973 -# The value of `cats` is used as a newline-separated list of
2974 -# default categories for any post coming from a particular feed.
2975 -# (In the example above, any posts from this feed will be placed
2976 -# in the "computers" and "web" categories--*in addition to* any
2977 -# categories that may already be applied to the posts.)
