/*!
Disabling parts of the default format.
Before running this example, try setting the `MY_LOG_LEVEL` environment variable to `info`:
```no_run,shell
$ export MY_LOG_LEVEL='info'
```
Also try setting the `MY_LOG_STYLE` environment variable to `never` to disable colors
or `auto` to enable them:
```no_run,shell
$ export MY_LOG_STYLE=never
```
If you want to control the logging output completely, see the `custom_logger` example.
