This plugin uses tidy to tidy up the html emitted by ikiwiki. Besides being nicely formatted, this helps ensure that even if users enter suboptimal html, your wiki generates valid html.

Note that since tidy is an external program, that is run each time a page is built, this plugin will slow ikiwiki down somewhat. htmlbalance might provide a faster alternative.
