### libWrapper
|
||||
|
||||
This module uses the [libWrapper] library for wrapping core methods. It is only
|
||||
a soft dependency (a shim is provided) but it is highly recommended to install
|
||||
libWrapper as a module for the best experience and compatibility with other
|
||||
modules.
|
||||
|
||||
## Usage
|
||||
|
||||
In order to configure the darkness range in which a token has dim and bright
