+/**
+ *
+ * This plugin adds Disqus commenting to your notices. Enabling this
+ * plugin will make each notice page display the Disqus widget, and
+ * notice lists will display the number of commments each notice has.
+ *
+ * To use this plugin, you need to first register your site with Disqus
+ * and get a Discus 'shortname' for it.
+ *
+ * http://disqus.com
+ *
+ * To enable the plugin, put the following in you config.php:
+ *
+ * addPlugin(
+ * 'Disqus', array(
+ * 'shortname' => 'YOURSHORTNAME',
+ * 'div_style' => 'width:675px; padding-top:10px; position:relative; float:left;'
+ * )
+ * );
+ *
+ * NOTE: the 'div_style' in an optional parameter that passes in some
+ * inline CSS when creating the Disqus widget. It's a shortcut to make
+ * the widget look OK with the default StatusNet theme. If you leave
+ * it out you'll have to edit your theme CSS files to make the widget
+ * look good. You can also control the way the widget looks by
+ * adding style rules to your theme.
+ *
+ * See: http://help.disqus.com/entries/100878-css-customization
