Feature idea: I'd like to be able to tag pages in an ikiwiki blog with a
publication date, and have the option of building a blog that excludes
publication dates in the future. (meta pubdate= ?)

I'm using ikiwiki on git for a "tip of the day" RSS feed, and I'd like to
be able to queue up a bunch of items instead of literally putting in one
tip per day. In the future I think this will come in handy for other
