+* authorurl
+
+ Specifies an url for the author of a page.
+
+* permalink
+
+ Specifies a permanent link to the page, if different than the page
+ generated by ikiwiki.
+
+* date
+
+ Specifies the creation date of the page. The date can be entered in
+ nearly any format, since it's parsed by [[cpan TimeDate]].
+
+* stylesheet
+
+ Adds a stylesheet to a page. The stylesheet is treated as a wiki link to
+ a `.css` file in the wiki, so it cannot be used to add links to external
+ stylesheets. Example:
+
+ \[[meta stylesheet=somestyle rel="alternate stylesheet"
+ title="somestyle"]]
+
+* openid
+
+ Adds html <link> tags to perform OpenID delegation to an external
+ OpenID server. This lets you use an ikiwiki page as your OpenID. Example:
+
+ \\[[meta openid="http://joeyh.myopenid.com/"
+ server="http://www.myopenid.com/server"]]
+
+* redir
+
+ Causes the page to redirect to another page in the wiki.
+
+ \[[meta redir=otherpage]]
+
+ Optionally, a delay (in seconds) can be specified. The default is to
+ redirect without delay.
+
+ It can also be used to redirect to an external url. For example:
+
+ \[[meta redir="http://example.com/"]]
+
+ However, this latter syntax won't be allowed if the [[htmlscrubber]] is
+ enabled, since it can be used to insert unsafe content.
