2041 +#
2042 +# key: value
2043 +# cats: computers\nweb
2044 +# feed/key: value

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").
