1709 - # randomly within a window of 30 minutes - 2 hours).

1712 - # --------

1722 - # --------

1738 - # module elements) or else from a randomly-generated time window

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

2957 -#
2958 -# * link_rss: the URI of the Atom/RSS feed to syndicate
2959 -#
2960 -# * link_notes: user-configurable options, with keys and values

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").
