\\[[meta openid="http://joeyh.myopenid.com/"
server="http://www.myopenid.com/server"]]
+* link
+
+ Specifies a link to another page. This can be used as a way to make the
+ wiki treat one page as linking to another without displaying a user-visible
+ [[ikiwiki/WikiLink]]:
+
+ \[[meta link=otherpage]]
+
+ It can also be used to insert a html <link> tag. For example:
+
+ \[[meta link="http://joeyh.myopenid.com/" rel="openid.delegate"]]
+
+ However, this latter syntax won't be allowed if the [[htmlscrubber]] is
+ enabled, since it can be used to insert unsafe content.
+
* redir
Causes the page to redirect to another page in the wiki.
For both cases, an anchor to jump to inside the destination page may also be
specified using the common `PAGE#ANCHOR` syntax.
+* robots
+
+ Causes the robots meta tag to be written:
+
+ \[[meta robots="index, nofollow"]]
+
+ Valid values for the attribute are: "index", "noindex", "follow", and
+ "nofollow". Multiple comma-separated values are allowed, but obviously only
+ some combinations make sense. If there is no robots meta tag, "index,
+ follow" is used as the default.
+
+ The plugin escapes the value, but otherwise does not care about its
+ contents. In particular, it does not check the values against the set of
+ valid values but serves whatever you pass it.
+
If the field is not one of the above predefined fields, the metadata will be
written to the generated html page as a <meta> header. However, this
won't be allowed if the [[htmlscrubber]] is enabled, since it can be used to
