+/**
+ * Plugin to add Google Adsense to StatusNet sites
+ *
+ * This plugin lets you add Adsense ad units to your StatusNet site.
+ *
+ * We support the 4 ad sizes for the Universal Ad Platform (UAP):
+ *
+ *     Medium Rectangle
+ *     (Small) Rectangle
+ *     Leaderboard
+ *     Wide Skyscraper
+ *
+ * They fit in different places on the default theme. Some themes
+ * might interact quite poorly with this plugin.
+ *
+ * To enable advertising, you must sign up with Google Adsense and
+ * get a client ID.
+ *
+ *     https://www.google.com/adsense/
+ *
+ * You'll also need to create an Adsense for Content unit in one
+ * of the four sizes described above. At the end of the process,
+ * note the "google_ad_client" and "google_ad_slot" values in the
+ * resultant Javascript.
+ *
+ * Add the plugin to config.php like so:
+ *
+ *     addPlugin('Adsense', array('client' => 'Your client ID',
+ *                                'rectangle' => 'slot'));
+ *
+ * Here, your client ID is the value of google_ad_client and the
+ * slot is the value of google_ad_slot. Note that if you create
+ * a different size, you'll need to provide different arguments:
+ * 'mediumRectangle', 'leaderboard', or 'wideSkyscraper'.
+ *
+ * If for some reason your ad server is different from the default,
+ * use the 'adScript' parameter to set the full path to the ad script.
