+* For PlaceWiki I want to be able to do some custom plugins, including one
+ that links together subpages about the same place created by different
+ users. This seems to call for a plugin that applies to every page w/o any
+ specific marker being used, and pre-or-post-processes the full page
+ content. It also needs to update pages when related pages are added,
+ so it needs to register dependencies pre-emptively between pages,
+ or something. It's possible that this is a special case of backlinks and
+ is best implemented by making backlinks a plugin somehow. --[[Joey]]
