Is my pleasure to announce a new library for managing configuration values on Haskell projects.

Some features:

* Have a versioned spec of all values your application can accept

* Provides an API for gathering values from multiple sources (files, overwrite files, cli arguments, environment variables) and then composing them into a single configuration map

* Gives a sane precedence over sources of the configuration value sources

* Provides inspection utilities to understand why the configuration is the way it is

* Provides an API that abstracts away the source of configuration values and allows easy casting into record types your application or other libraries understand

* Supports both configuration files in JSON or YAML (when cabal flags are used)

* Dynamically generates CLI inputs from spec configuration file

Any feedback, or comments feel free to create a ticket or send me a tweet over at @romanandreg

Cheers.
