Description:
JSON library for Ruby
This library implements the JSON (JavaScript Object Notation) specification in Ruby, allowing the developer to easily convert data between Ruby and JSON. You can think of it as a low fat alternative to XML, if you want to store data to disk or transmit it over a network rather than use a verbose markup language.
