2707 +# To keep things compact and editable from within WordPress, we use all the
2708 +# links under a particular category in the WordPress "Blogroll" for the list of
2709 +# feeds to syndicate. "Contributors" is the category used by default; you can
2710 +# configure that under Options --> Syndication.
2711 +#
2712 +# Fields used are:
2713 +#
2714 +# * link_rss: the URI of the Atom/RSS feed to syndicate
2715 +#
2716 +# * link_notes: user-configurable options, with keys and values
2717 +# like so:
2718 +#
2719 +# key: value
2720 +# cats: computers\nweb
2721 +# feed/key: value
2722 +#
2723 +# Keys that start with "feed/" are gleaned from the data supplied
2724 +# by the feed itself, and will be overwritten with each update.
2725 +#
2726 +# Values have linebreak characters escaped with C-style
2727 +# backslashes (so, for example, a newline becomes "\n").
2728 +#
2729 +# The value of `cats` is used as a newline-separated list of
2730 +# default categories for any post coming from a particular feed.
2731 +# (In the example above, any posts from this feed will be placed
2732 +# in the "computers" and "web" categories--*in addition to* any
2733 +# categories that may already be applied to the posts.)
