-This would allow ikiwiki to work as a kind of a planet, or at least a
-poor-man's news aggregator.
-
-* XML::Feed has a very nice interface, may require valid feeds though.
-* How to store GUIDs? Maybe as meta tags on pages, although that would need
- caching of such metadata somewhere.
-* How to configure which feeds to pull, how often, and where to put the
- pulled entries? One way would be command line/config file, but I think
- better would be to use preprocessor directives in a wiki page, probably
- the same page that inlines all the pages together.
-* Where to store when a feed was last pulled?
-
-So I need:
-
-* A way to store info from the preprocessor directives about what pages
- to pull and expiry.
-* A way to store info on last pull time, guids, etc.
-* Switch for a mode that a) pulls b) expires old c) rebuilds wiki (for cron)
