App::Music::ChordPro::Config - Configurator.
This module first establishes a well-defined (builtin) configuration.
Then it processes the config files specified by the envitronment and adds the information to the global $config hash.
The configurations files are 'relaxed' JSON files. This means that they may contain comments and trailing comma's.
This module can be run standalone and will print the default config.
The default configuration as built in. User and system configs go on top of this one.
See https://www.chordpro.org/chordpro/chordpro-configuration/ for extensive details and examples.
