Internal Program Version: jsoncpp  1.9.6

JSON is a lightweight data-interchange format. It can represent
numbers, strings, ordered sequences of values, and collections of
name/value pairs.

JsonCpp is a C++ library that allows manipulating JSON values,
including serialization and deserialization to and from strings. It
can also preserve existing comment in unserialization/serialization
steps, making it a convenient format to store user input files.
