- *
- * $item - item array or item id. If passed an array the iconfig meta information is
- *    added to the item structure (which will need to be saved with item_store eventually).
- *    If passed an id, the DB is updated, but may not be federated and/or cloned.
- * $family - namespace of meta variable
- * $key - key of meta variable
- * $value - value of meta variable
- * $sharing - boolean (default false); if true the meta information is propagated with the item
- *   to other sites/channels, mostly useful when $item is an array and has not yet been stored/delivered.
- *   If the meta information is added after delivery and you wish it to be shared, it may be necessary to 
- *   alter the item edited timestamp and invoke the delivery process on the updated item. The edited 
- *   timestamp needs to be altered in order to trigger an item_store_update() at the receiving end.
