  * Description: Use Geonames service to resolve nearest populated location for given latitude, longitude
  * Version: 1.0
  * Author: Mike Macgirvin <http://macgirvin.com/profile/mike>
- *
- *
- * Pre-requisite: Register a username at geonames.org
- * and set in config/addon.config.php
- *
- * [geonames]
- * username = your_username
- *
- * Also visit http://geonames.org/manageaccount and enable access to the free web services
- *
- * When addon is installed, the system calls the addon
- * name_install() function, located in 'addon/name/name.php',
- * where 'name' is the name of the addon.
- * If the addon is removed from the configuration list, the
- * system will call the name_uninstall() function.
