-How about adding a deprecated tag in order to clean up the plugin list?

-For instance [[googlecalendar]] is listed as plugin but should probably be removed from Ikiwiki in a future major version (v3?).

-*Note*: This plugin is deprecated. Please switch to the [[embed]] plugin.

-This plugin allows embedding a google calendar iframe in the wiki.
-Normally, if the [[htmlscrubber]] is enabled, such iframes are scrubbed out
-of the wiki content since they're not very safe if created by malicious
-users. But some iframes are legitimate, and safe, if you trust the embedded
-content. This plugin is an example of how to deal with this in ikiwiki.
-
-Example use:
-
-	\[[!googlecalendar html="""
-	<iframe src="http://www.google.com/calendar/embed?src=adkrdken8mupngh13jshlbenoc%40group.calendar.google.com&title=OSEL%20Calendar&chrome=NAVIGATION&bgcolor=%2371d873&height=588" style=" border-width:0 " width="480" frameborder="0"	height="588"></iframe>

-The iframe should be the one provided by google. Note that it's used in a
-way that avoids cross-site scripting attacks, assuming you trust google's
-content.
