This plugin uses [tidy](http://tidy.sourceforge.net/) 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.
-This plugin is included in ikiwiki, but is not enabled by default.

+Note that since tidy is an external program, that is run each time a page
+is built, this plugin will slow ikiwiki down somewhat.
