Plugin to tag external urls as rel=external.
All external urls are marked with a rel="external" attribute. It also optionally adds a class to external links.
You can write your code with usual <a href="http://google.com"> etc, and the plugin will apply this atribute to correct links. (For example for styling external links differently.)
$("body").externalify()
will apply rel="external" to all links on the page.
or
$("#article").externalify({"class": "external"})
will apply rel="external", class="external" on all links in #article selector.
