+ * Metadata for configuration manager plugin
+ *
+ * Note:  This file should be included within a function to ensure it 
+ *        doesn't class with the settings it is describing.
+ *
+ * Format:
+ *   $meta[<setting name>] = array(<handler class id>,<param name> => <param value>);
+ *
+ *   <handler class id>  is the handler class name without the "setting_" prefix
+ *
+ * Defined classes:
+ *   Generic
+ *   -------------
+ *   ''             - default class ('setting'), text input, minimal input validation, setting output in quotes
+ *   'numeric'      - text input, accepts numbers and arithmetic operators, setting output without quotes
+ *   'onoff'        - checkbox input, setting output  0|1
+ *   'multichoice'  - select input (single choice), setting output with quotes, required _choices parameter
+ *   'email'        - text input, input must conform to email address format, setting output in quotes
+ *   'password'     - password input, minimal input validation, setting output plain text in quotes
+ *   'dirchoice'    - as multichoice, selection choices based on folders found at location specified in _dir
+ *                    parameter (required)
+ *
+ *  Single Setting
+ *  --------------
+ *   'savedir'     - as 'setting', input tested against initpath() (inc/init.php)
+ *   'sepchar'     - as multichoice, selection constructed from string of valid values
+ *   'authtype'    - as 'setting', input validated against a valid php file at expected location for auth files
+ *   'im_convert'  - as 'setting', input must exist and be an im_convert module
+ *
+ *  Any setting commented or missing will use 'setting' class - text input, minimal validation, quoted output
+ *
+ * Defined parameters:
+ *   '_pattern'    - string, a preg pattern. input is tested against this pattern before being accepted
+ *                   optional all classes, except onoff, multichoice & dirchoice which ignore it
+ *   '_choices'    - array of choices. used to populate a selection box. choice will be replaced by a localised
+ *                   language string, indexed by  <setting name>_o_<choice>, if one exists
+ *                   required by 'multichoice' class, ignored by other classes
+ *   '_dir'        - location of directory to be used to populate choice list
+ *                   required by 'dirchoice' class, ignored by other classes
+ *
