- * MSG user, you will only rarely manipulate any of these objects
- * directly, since most of the public interface (such as
- * #MSG_task_send and friends) hide this object behind a string
- * alias. That mean that you don't provide the mailbox on which you
- * want to send your task, but only the name of this mailbox. */
