module Lug::Standard

Standard module extends Lug classes so that it behaves similarly to traditional Logger classes.

It basically adds methods for writing messages in different severity levels: `#debug`, `info`, `#warn`, `#error`, `#fatal`, `#unknown`. These methods also accept a block instead of a string, and will call it only if it needs to (in particular, if message level is greater than logger's severity level).

By default, severity level is `DEBUG`, but you can set this threshold with the `LOG_LEVEL` environment variable.

You can mix these methods with `#log` or `#<<`, but messages logged with `#log` will behave like messages with `DEBUG` level. This means you will see them only if severity level is set to `DEBUG`.
