2029 -#
2030 -# To keep things compact and editable from within WordPress, we use all the
2031 -# links under a particular category in the WordPress "Blogroll" for the list of
2032 -# feeds to syndicate. "Contributors" is the category used by default; you can
2033 -# configure that under Options --> Syndication.
2034 -#
2035 -# Fields used are:
2036 -#
2037 -# * link_rss: the URI of the Atom/RSS feed to syndicate
2038 -#
2039 -# * link_notes: user-configurable options, with keys and values
2040 -# like so:
2041 -#
2042 -# key: value
2043 -# cats: computers\nweb
2044 -# feed/key: value
2045 -#
2046 -# Keys that start with "feed/" are gleaned from the data supplied
2047 -# by the feed itself, and will be overwritten with each update.
2048 -#
2049 -# Values have linebreak characters escaped with C-style
2050 -# backslashes (so, for example, a newline becomes "\n").
2051 -#
2052 -# The value of `cats` is used as a newline-separated list of
2053 -# default categories for any post coming from a particular feed.
2054 -# (In the example above, any posts from this feed will be placed
2055 -# in the "computers" and "web" categories--*in addition to* any
2056 -# categories that may already be applied to the posts.)
2057 -#

2059 -# the function `get_feed_meta($key)` if this plugin is activated.
