+/*!
+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.
