@hackage conftrack0.0.1

A library for handling multiple config files and keep track of where config values came from.

Config values can be read from json, yaml, or environment variables; it is also possible to implement custom configuration sources via a type class.

Provenance of config values is tracked while reading them; an application using this library can easily print a listing detailing which files were read and which file provided (or failed to provide) an individual value.
