|

* to filename and new log file is created. Can be integer bytes value or

|
| 81 |
* - `rotate` Log files are rotated specified times before being removed.
|
| 82 |
* If value is 0, old versions are removed rather then rotated.
|
| 83 |
* - `mask` A mask is applied when log files are created. Left empty no chmod
|
| 84 |
* is made.
