| 15 |  |  |  |  |  |  |  | 
| 16 |  |  |  |  |  |  | Net::DNS::ZoneParse::Generator::Native - Net::DNS::ZoneParse's native generator. | 
| 17 |  |  |  |  |  |  |  | 
| 18 |  |  |  |  |  |  | =head1 DESCRIPTION | 
| 19 |  |  |  |  |  |  |  | 
| 20 |  |  |  |  |  |  | The native generator generates valid files, which can be read by most parsers. | 
| 21 |  |  |  |  |  |  | If the corresponding information is available, it will generate correct | 
| 22 |  |  |  |  |  |  | $TTL and $ORIGIN directives and - at least for the name of the resource records | 
| 23 |  |  |  |  |  |  | shorten the names, if applicable. |
