- * This function performs actions required due to the occurrence of the given

+ * This function updates the score table according to the event that has

+ * add/remove/update the row of the score table which corresponds to the audio
+ * file that has been modified or whose afs info has been changed. It depends

+ * The callbacks of command handlers such as com_add() or com_touch() which

+ * stream (the one with the highest score). If the file stays admissible, its
+ * score is recomputed so that a different file is picked next time.
