libunivalue-dev 1.1.1+20191111-1 (ppc64el binary) in ubuntu hirsute

 A universal value object, with JSON encoding (output) and decoding
 (input).
 .
 Built as a single dynamic RAII C++ object class, and no templates.
 .
 UniValue is a reaction to json_spirit,
 seeking to minimize template and memory use,
 providing a straightforward RAII class
 compatible with link-time optimization and embedded uses.
 .
 This package provides header files for development.
