+=item reverse_record

+Returns the corresponding reverse-ARPA record as another FS::domain_record
+object.  If the specific record does not exist in the database but the 
+reverse-ARPA zone itself does, an appropriate new record is created.  If no
+reverse-ARPA zone is available at all, returns false.
+
+(You can test whether or not record itself exists in the database or is a new
+object that might need to be inserted by checking the recnum field)
+
+Mostly used by the insert and delete methods - probably should see them for
+examples.
