* When populating this file, consider the following flow
* of control:
*
* - Check if the $_REQUEST['plugin'] content actually is coupon/coupon.php
* - Check if the $_REQUEST['action'] content actually is delete-plugin
* - Run a check_ajax_referer check to make sure it goes through authentication
* - Run a current_user_can check to make sure current user can delete a plugin
*
* @todo Consider multisite. Once for a single site in the network, once sitewide.
