The YAML 1.2 format provides a much richer data-model and feature-set than the JavaScript Object Notation (JSON) format. However, sometimes it's desirable to ignore the extra capabilities and treat YAML as if it was merely a more convenient markup format for humans to write JSON data. To this end this module provides a compatibility layer atop HsYAML which allows decoding YAML documents in the more limited JSON data-model while also providing convenience by reusing aeson's FromJSON instances for decoding the YAML data into native Haskell data types.
