JSON (JavaScript Object Notation) is a lightweight data-interchange
format. It is easy for humans to read and write. It is easy for
machines to parse and generate. It is based on a subset of the
JavaScript Programming Language, Standard ECMA-262 3rd Edition -

This library provides a parser and pretty printer for converting
between Haskell values and JSON.
